Do You Need a New Boiler? 

Here at Greener Homes, we know how important it is that your home has a quality boiler that is capable of heating your whole property in an energy-efficient way. Below we’ve highlighted many of the factors that are tried and tested forms of knowing when you need a new boiler. 

When Should You Get a New Boiler? 

Having a new boiler installed can cost a fair bit of cash, so it’s understandable that you want to know you’re doing the right thing before you pull the trigger on a new boiler installation. 

Below we’ve highlighted the main factors to consider if you’re wondering if it’s time to get a new boiler. 

Main Factors to Consider

  • Regular repairs – If you find yourself having multiple visits from your boiler engineer in one year then it may be time to start thinking about that new boiler. Not to mention that new parts can be costly especially on older models of boiler that may not be in production anymore. 
  • Strange Noises – If you hear strange noises in the night or in the day for that matter, then it’s probably best you don’t call the ghostbusters those guys have got their hands full catching actual spooks. In fact, those noises could well be caused by a boiler that isn’t working correctly. Knocking, popping and hissing sounds are common on boilers that are likely to conk out. This is a definite sign you need an engineer and may well need a new boiler. 
  • Inconsistent Temperature – if you find the temperature of your water fluctuates or runs immediately cold then this could be a sign that your boiler isn’t working correctly. 
  • Boiler Leak – Any leak in your home should be investigated. Especially one you suspect is coming from your boiler. A leaky boiler can lead to a carbon monoxide leak which can be extremely dangerous.
  • Smart Technology-Enabled – it’s 2021 we live in the future! Unfortunately, we haven’t quite gotten to the flying cars just yet. But you can control your boiler with your smart device. And that means more convenience for you when it comes to heating your house. 
  • Increase in your Bills – If you find your bills unexpectedly rising it may mean that your boiler is no longer energy efficient. A modern A-rated boiler may well run at 90% efficiency. Whilst older G-rated models could run at 70% or less efficiency. 

5 Things to Do Before You Get a New Boiler 

Now we’ve been through the main factors that will contribute to you making a decision on whether or not you need a new boiler. We’re going to cover the 5 things to do before you get a new boiler. 

Before you get your new boiler installation booked, it’s probably a good idea to do these things. To ensure you get the right boiler for your property at a price that suits your wallet. 

1. Choose a Trusted Brand

When you’re looking at the boiler market the amount of choice on offer may well seem overwhelming. Whilst it might seem like an attractive offer to pick the cheapest boiler, it won’t offer you the sort of quality guarantee that one of those more well known trusted brands can. 

Here at Greener Homes, we offer a variety of different brands when it comes to boilers. Including boilers from market leaders like Worchester Bosch, Valiant, Ideal, Baxi, and more. 

2. Ask the Engineer

We don’t expect everybody to be an expert on boilers, so, asking your engineer what the best option is for you is an excellent idea. Most engineers will have experience installing a multitude of different boilers. And can probably help guide you to what would be the correct boiler system for your property. 


3. Check the Warranty

Many boilers come with warranties, but it may pay to shop around as not all warranties are created equal. Some boilers can come with up to a whopping 12-year guarantee. So his is another factor to take into consideration before you get a new boiler. 

4. Find the Right Boiler

Whilst there is a multitude of different brands to choose from there are only three main types of boiler that will be suitable for your property. 

The three boiler types are as following : 

  • Combination 
  • Regular
  • System

5. Get Quotes

Getting a new boiler installed definitely isn’t the cheapest thing in the world to do. It is best to get more than one quote and ensures that you get yourself the best possible deal you can. Although, beware the cheapest deal may not always be the correct one for your property. 

A New Boiler VS Repairing Again 

If you’re trying to weigh up the cost difference between having your boiler replaced or fixing your old one there are a few things you should consider that we haven’t really previously touched on in this article. 

  • Over 10 Years Old – Most manufacturers will stop making replacement parts for their boilers around the 10-year mark this will impact the cost and availability of parts. 
  • Repair Costs – You’ll have to work hard to find a plumber who’s call rate doesn’t range in the £60- £100 region. And repairs can often cost around £150- £300. Your bill for one repair could potentially cost you £500. If your boiler needs more than one repair like this you can see how it may well be worth spending a little extra to have a new boiler installed.

In the next part of this article we’re going to take you through the different types of fuels and boilers you’ll need to know about before getting a new boiler.

The 3 Main Types of Boilers 

At Greener Homes, we have a long history of installing all types of boilers. We have broked down the 3 main types of boilers to help you understand which one you will need for your property. If you are still unsure, it is best to speak to a heating engineer.

There are three main types of boiler that are commonly used to heat properties across the country. Which type of boiler you will require will largely depend on the current hot water demands of the property. Although other factors such as age and water pressure will be taken into account. 

The three main types of boilers are the combi, conventional, and system boiler. Now we’re going to look at each type of boiler and explore its advantages and disadvantages. 

Combi Boiler 

The Combi boiler is easily the most popular choice for most homes across the country thanks to their space-saving all-in-one solution to heating your property. 

A combi boiler doesn’t use hot water storage or a cold water tank. Instead, combi boilers heat the water directly from the mains. Combi boilers are also considered to be more energy-efficient and cost-effective than other types of boilers. Although great for small homes this option may not be the best for larger homes or homes with greater water demands (more than one bathroom). One major drawback is if your combi boiler does conk out it may well leave you without heating and hot water. As there’s no hot water storage contained within the unit. 


  • Compact System
  • Energy Efficient
  • Cost-Effective 
  • Hot Water on Demand 
  • Easy to Install and Maintain 


  • Requires Good Mains Pressure 
  • Can’t Use More than One Bath or Shower at Once 
  • Not Compatible will All Showers 
  • No Back-Up Water Heater 

System Boiler 

A perfect choice for homes with greater water demands (more than one bathroom). Unlike combi boilers, system boilers require a hot water storage cylinder. However, they don’t use water tanks because most of the components are housed inside the unit. Disposing of the need for a water tank allows homeowners to maintain their units easier. And eliminates some of the worries of frost induced damage and leaks. 

If you have a larger home but, you don’t have the space for a water tank this option could be the best choice for your property. 


  • Compact Design 
  • Constant Hot Water 
  • Use Multiple Taps 
  • No Cold Water Tank 
  • Stronger Water Pressure 
  • Compatible with Solar Thermal 


  • Hot Water Can Run Out 
  • Need Space For Cylinder 
  • Insulation Needed 

Conventional Boiler 

A conventional or regular boiler uses both a hot water cylinder and a cold water tank. So this might not be the best option for those with space concerns. However, a conventional boiler is capable of supplying your home with large volumes of hot water.

A conventional boiler will typically be installed into homes where there was already a conventional boiler in place. Although still a great option for those with larger homes with multiple bathrooms. 


  • Use multiple Taps at Once 
  • Good for Low-Pressure Areas 
  • Compatible with Solar Thermal 
  • Back up Immersion Heater 


  • Not Space Efficient 
  • Needs Insulation 
  • Wait for Hot Water 
  • Complicated install 

We’ve covered the three main types of boiler you’ll come across when you’re looking at new boilers. Now, we’re going to take a look at the three main types of fuels that are used to run boilers. 

The 3 Main Types of Fuel for Boilers 


When looking at the different types of fuels used by boilers, gas boilers are by far the most common type of boiler used. Gas boilers come in all varieties of boiler previously mentioned (conventional, combi, and system). Gas boilers are fueled either by natural gas that is delivered to the boiler from the gas mains or by an LPG (Liquefied Petroleum Gas).

LPG is more expensive but, for those who don’t have access to the mains gas line and still want to use gas, this is the only option. 

However, if you have access to the mains gas line then gas is by far the cheapest and most reliable option for firing your boiler. 


  • Convenient 
  • Easy to Use 
  • Never run out (Mains) 
  • Can be used with all boiler types 
  • Cost-efficient 
  • Energy efficient 


  • Installing from scratch can be costly and disruptive 
  • Produces Carbon Dioxide (not green friendly) 


Oil is often used by those properties that are in rural parts of the country as they don’t have access to the mains gas lines. This is becoming an increasingly more popular option these days as it’s considered to be more energy efficient than other fuels. 

However, the cost of operating an oil fired boiler can fluctuate depending on oil prices. Although, most homeowners who operate on an oil boiler usually purchase oil in the summer when oil prices are at their cheapest. 


  • Great for Rural Areas 
  • The option when to buy fuel 


  • Fluctuating Fuel Prices 
  • Not Green Friendly 


And the final most common fuel type used to fire boilers is electric. Electric is another option for those who don’t have access to the main gas line. Electric is quite an energy-efficient way to fuel your boiler. But it might not be the best option for your wallet as it can be quite expensive to run when compared to other fuels.

Electric boilers also use less pipework and the installation is generally easier and quicker than gas and oil. 


  • Energy Efficient 
  • Clean 
  • Easy to Install 
  • Compact 
  • Available Everywhere 


  • Not Very Cost Efficient 
  • Not Great for Larger Homes 

Now we’ve taken a look at the three main fuels that are used in homes up and down the country. Hopefully, this will help you as you move toward a decision about what boiler is right for your property.

What Will a New Boiler Cost?

Now we’ve discovered the different types of boilers and fuels that can run them you’re probably asking yourselves ‘how much does a boiler cost?’. Your boiler is probably the single most important item in your home. Especially when it comes to those icy cold winter months. So it’s probably best that you’ve ensured you’ve made the right decision before you have any boiler installed. 

New boilers, as you can probably imagine, aren’t the cheapest item you’ll buy for your home. Typically if you’re looking at having a new boiler installation you can expect to be spending around £500 to the region of £2500 in price. However, you’ll be compensated by the smaller bills which will equal larger savings down the line. We’ll go slightly deeper into this later on.

In fact, by installing a new boiler in your property you could be saving yourself anywhere from £50-£305. It all depends on your current water demands and the size of your property. For instance, if you have a G-rated boiler and you live in a mid-floor flat you stand to save £95 a year.

However, if you were to have a G-rated boiler in a semi detached home you could stand to save up to £300 a year. So with savings as large as that you can see how having a new boiler installed will almost pay for itself in 3-5 years. 

How Much is a New Boiler Fitted?

The price of your boiler installation will depend on a few different factors these will include:

  • Type of Boiler 
  • Replacement or New Boiler 
  • Moving the Boiler 
  • Optional Extras (smart controls/filters) 

It doesn’t matter what your budget there should be an option that is right for you. If you’re still unsure and would like to quote on having a boiler installation then please visit us here.

Later in the article, we’ll go into further detail and offer up some potential scenarios to help you wrap your head around the subject a bit more

How Much is a Boiler on Its Own? 

A lot of people like to know how much each component of the installation will cost to help them decide which boiler option is right for them. After all your budget will be one of the deciding factors that influences your decision. So we are now going to delve further into this and take a look at how much a boiler costs on its own.

New combi and system boilers can range between £500 -£1000 on most budget models. Mid-range models will cost from £1000-£1200. And premium models often will cost in excess of £1500. 

Conventional boilers can cost between £500 and £2000 depending on the size, brand, and quality of the unit. 

Now we’ve taken a look at the average prices of the boiler units themselves, we’re going to take a look at some scenarios and breakdown the potential cost for each one. 

Boiler Installation Cost Scenarios: 

The amount the boiler installation will cost will depend on the amount of labour that is required to complete the job. Prices can vary based on your location (large cities such as London tend to be more expensive). And eve the company you use. Other things that can impact the price of the installation is if you need extra pipework to alter the location of the boiler. 

Now we’re going to go through each boiler type and cover how much you should be expecting to spend on your new boiler installation. 

Combi Boiler

Having a new combi boiler installed could cost you £1500 -£4000. The price here will reflect the full installation, boiler, any included warranties, and how complex the installation is to complete. Again labour costs will vary depending on your area.

Replacing a combi boiler will take one day. Whilst you could expect to see job times of 2-3 days to move the boiler to a new location in your home. 

System Boiler

Replacing a system boiler with a new system boiler will probably only take one day to complete. And a mid-range boiler will cost up to £2000 including the boiler, installation, and warranties.

As with all of the boiler types mentioned, there are three main tiers of price that they fit into your budget. Mid and premium prices will vary depending on what your specific water demands and budget are. 

Conventional Boiler

Conventional boilers usually lay at the more expensive end of the spectrum as far as price is concerned. As with all of the above boilers, there are a number of factors that will be taken into consideration when you receive your quote for having a conventional boiler installed. Prices can run the entire gambit between £1500- £3000.

Conventional boilers require a hot water cylinder to function. These prices typically do not include the price of the hot water cylinder and this may be something that you wish to purchase separately. 

Thermostatic Valves

One item we have briefly mentioned is the valve. More accurately known as thermostatic radiator valves or those little do hickeys with numbers on that some radiators have, yeah those. These valves are an effective way of ensuring that each room of your house has the optimal amount of heating. Typically each of these radiator valves will cost you in the region of £15 each.

As you can tell there are a number of factors that will have to be taken into consideration when figuring out how much your boiler will cost. Having extra pipework, changing the location of your boiler, the size of the boiler and if you require any additional controls or valves will all impact the final price of your boiler installation.

Next, we are going to talk about the cost of having a boiler installation with Greener Homes. As well as take you through what to expect if you want to have a boiler installation with us.

Once the day of your appointment arrives, one of our engineers will promptly arrive to investigate your home. And they will give you your free quote for your new boiler installation. 

The quote will be based on the brand, type of boiler, price point, and where your boiler will be situated once it’s installed. We’ll take into consideration the hot water demands of your home, how many radiators you have, and what your current boiler system is.

Once we’ve taken into account all of these factors we will be able to advise you on what boiler we think could be a good option for your home. 

Decide on Your New Boiler

Once the engineer has assessed your home for its hot water demand they’ll be able to advise you on what boiler might be a good fit for your property. In most cases, people opt to have a like for like replacement. As this is often the cheapest and quickest solution. 

Like for like refers to replacing the old boiler with a similar more modern model. This will allow the engineer to complete the task in a timely fashion. And is a lot quicker than having a different boiler type installed.

Brand of Boiler

The brand of boiler is another thing to consider. While some brands might seem like they offer a great deal, however, they might not have the market recognisability of more established brands. Making parts harder to come by in the event of something going wrong. This may well impact the length of the warranty you can receive on purchasing your boiler too. 

Here at Greener Homes, we specialise in installing Worcester Bosch Boilers. Worcester Bosch has been the market leader in the home boiler space for many years. And has won several awards for their innovation and quality across the board with all their products. 

Average Costs for a Boiler From Greener Homes 

As we’ve just covered here at Greener Homers we are accredited Worcester Bosch installers. They’re our favourite brand for several reasons but, by far is their attention to quality even with their more budget options. 

At the cheaper end of the spectrum, you would expect to spend as little as £1500. While the upper end of the market could see you spend in the region of £4000. With these amounts, it would be good to take into account some of the amazing warranties that Worcester Bosch offers to those who purchase their boilers through an accredited installer like us!

Some of their warranties can last up to 12 years and when you consider that most people will think of a 10-year-old boiler as an old boiler that might be ‘replaceable’ I’m sure you’ll agree this shows some amazing value for money. 

At Greener Homes, we also offer a finance program. Which allows you a flexible way to pay for your boiler and installation over a period of time. By spreading out the costs into monthly payments you may be able to have a high specification heating system. We work with Novuna who are experts at providing finance and flexible payment schemes to millions of homeowners across the country.

The Break Down of The Installation Cost 

For most people, they might consider that the price of a boiler installation can be summed by two factors. The cost of the boiler and the cost of the labour. 

Whilst this is true to a certain extent and you may well be able to get along just fine without having any more prior knowledge than this. Our team at Greener Homes firmly believes in allowing all of our customers to have all of the information about their installation if they require it. 

So, for the final part of this article, we’re going to break down the price of your installation. 

Below we’ve compiled a list of the 10 most common factors that contribute to the price of your boiler installation. 

1. The Boiler 

The heart of your home’s central heating system and probably the main thing you think about when looking at the price of your installation. The boiler. Many factors can impact the price of the boiler including the following – 

  • Brand 
  • Quality 
  • Model 
  • kW output 

Typically you can spend anywhere from £400-£1200 for a budget to mid-range model of boiler. 

2. Labour 

The other most obvious cost when it comes to the price of your installation is labour. The cost of the labour on an installation will depend on a few different factors including:

  • Size of Job 
  • Number of Engineers Required 
  • Complexity of Job 
  • Area 

Whilst prices do vary from area to area on average you can expect the labour fees for a boiler installation to be anywhere from £500-£1000. 

3. Flue 

The vertical flue is basically the exhaust for condensation and various not used gases to be expelled. They usually are a large pipe that comes out of the top of the boiler and exhausts to the outside of your premises. Typically the flue is installed through the wall, but, on occasion, this may not be possible. Instead, the flue would have to exit through the roof. This can be more costly than the previous method. 

Typical flue prices range from £300-£600. 

4. Plume Kit 

The plume kit can be summed up as an extension kit for the flue. The plume kit is used to extend the flue so it doesn’t cause any hazards such as being too close to a neighbouring property, window, or door. Having your boiler’s flue in the correct position is required to comply with the Gas Safety Regulations. 

In most cases, a plume kit can cost you on average £90-£140. 

5. Gas Upgrade 

If you’re upgrading from an older model you may well find that your heating system uses 15mm piping. Which doesn’t meet the current regulations. In most cases, the piping will need to be replaced with 22mm. Older piping can sometimes be made out of lead and other materials that won’t work with our current systems. So they have to be replaced with copper pipes. 

On average, depending on the complexity of the job, you’ll be looking to spend £250-£400 on having a gas upgrade in your property. 

6. Relocating Boiler 

One of the more costly aspects of a boiler installation is the relocation of the boiler. If that’s a route you’re planning on going then there are a few aspects to take into consideration as you breakdown the potential price of an installation. Moving the current pipework and adding new pipework will be highly likely. This will likely increase labour costs too. 

As we’ve previously covered earlier in this article. Most people opt to have a like for like replacement. But if your boiler’s current position is causing your life havoc then this is an option to consider. 

Prices to relocate your boiler will likely include:

  • Labour 
  • Pipework 
  • Potential Gas Upgrade 
  • Plume kit 

7. Heating Controls 

As we covered earlier in this article most modern boilers come with some sort of smart integration. Whether that’s a small LCD display or full smart technology, there’s plenty of ways to bring your boiler into the future.

As with most other things on this list, prices can vary depending on the brand and what type of controller you had in mind. 

Typical prices vary from £100-£350.

8. Warranties 

Getting a boiler with a good warranty seems like an obvious choice to make. A boiler usually is a reasonable amount of money and it only makes sense you’d want to protect that purchase for as long as possible. 

When you’re hunting for your boiler it’s a good idea to check what warranties come with it. Quite often accredited installers can offer greater warranties than you may receive elsewhere. 

For instance, on certain lines of Worcester Bosch boilers, we currently offer up to a 12-year guarantee. For more information please visit our website.

9. Magnetic Filters 

Magnetic Filters are essentially traps for small particles of dirt and metal. The filters catch all the debris to protect the surrounding pipework. This helps prevent boiler leaks and potential damage. In most cases, the cost of your filter will be factored into the price of your installation. 

The average price of Magnetic Filters £80-£200 

10. Chemical Flush 

Depending on the age of your home having to clean your radiators out or flush could be a necessary part of an installation. Flushing out any unwanted sludge from the pipework and radiators will allow the water to pass through them all with ease and heat your home efficiently. There are several different chemical flushes available on the market ranging in price from £80- £150. 

In severe cases, a power flush may be suggested this work by forcing large amounts of pressure through the pipework. This can be quite a costly excursion and can cost upwards of £500. 

As you can see although the purchase of a boiler installation can be broken down into the rather oversimplified Boiler/Labour model. There are many factors that will have to be taken into consideration before you can come to a decision of what boiler fits your needs the best.
