The boiler system uses a “dry cycle” that wastes energy, heating your home until it reaches the desired temperature.
The continuous pilot light on your boiler is a common feature in older boilers or waste gas.
Your boiler is currently rated G for energy efficiency.
This guide will provide you with an estimate of how much is a new boiler and any other costs that may be associated with your job.
As there are many factors to consider, it’s hard to determine the average cost of replacing a boiler. The boiler must be manufactured to a high standard. This is an important home investment that you shouldn’t make. It will end up costing you more long-term.
A new boiler can cost anywhere from £500 to £3,000, including labour. You can expect to pay between £2,000-£4,500 for a new boiler supply, and labour to install it.
These prices are only a guide. New boiler prices can vary. The right boiler will be required for your specific household. Before you decide to purchase a boiler, make sure you consult a Checkatrade boiler installation expert.
How much does it cost to replace a boiler?
The cost to install a boiler depends on whether the boiler is being replaced, converted, or moved. Converting a back boiler to a combination boiler can cost you between £3,000 to £5,000.
It would cost around £1,400 to £2,000 to swap a combi with another one. You could spend more if you moved it.
A choice of fitters is another reason you might see a significant difference in the cost of installing a new boiler. This could be because they can either work for large companies, small businesses, or sole traders. For your new boiler, sole traders might be available to help you fit it.
We have already discussed a few types of boilers. They are important to know so you can make the right decision for your home. Let’s now learn about the various types of boilers.
There are three types of boilers in the UK: regular, system, and combi. You are not sure what type of boiler your home has? If in doubt, use our quick guide below:
Checklist of quick boiler type
Combi boilers do not need storage tanks.
An airing cupboard can house a hot-water storage tank for a system boiler.
An airing cupboard will house a hot-water storage tank and an upper loft cold water storage tank for a regular boiler.
Notice: The cold water storage tank located in the loft should be checked. It may not be connected.
We have provided rough estimates for the cost of all boilers.
Combi boilers are able to draw water directly from the mains, and produce instant hot water.
Combi boilers allow you to have both stored hot and direct-fired heat water.
An immersion heater can provide hot water backup in the event that a boiler breaks down.
A traditional, tank-heated airing closet.
Unlimited hot water from one or more outlets
How much does it cost to install a combi boiler?
Installation and supply of a combi boiler typically costs £3,000. The cost of your new boiler installation depends on many factors, especially the age of the boiler.
Combi boiler installation costs will typically be higher if the boiler is being replaced by a different type.
There are many types of combi boilers
You have already decided on a combi-boiler, now you must choose the type. Although gas combi boilers are most common in the UK, you can also choose from LPG, oil and electric boilers.
Gas combi boilers, which use natural gas, are an option for all homes connected to the gas network. Gas boiler installation costs can be quite affordable compared with other options.
For homes without a gas connection, oil combi boilers can be used. The extra tanker and connections that are required to install an oil boiler can make installation more expensive.
LPG combi boilers, which use liquefied petroleum Gas (or LPG), are an efficient way to heat water.
Electric combi boilers heat water differently, heating it by passing it through a hot element and not burning fuel. Although electric combi boilers have the lowest operating costs, they are more expensive to run.
There are pros and cons to installing a combi boiler
Before you rush out to purchase and install a combi-boiler, weigh up the benefits and drawbacks.
Pros
High energy efficiency
Lower energy bills
Compact size
Installation is simple
Hot water upon demand
Cons
Not recommended for large homes
It can be incompatible to old pipework
It is not suitable for homes with low main pressure water.
Gas combi boiler installation costs
Gas combi boilers can be energy-efficient and small in size which will result in lower energy bills. Hot water is available on demand, which can be a great benefit in colder months.
Unfortunately, gas combi boilers work best in smaller homes and are not compatible with older pipes.
A combi boiler will cost you approximately £2,400 + VAT to install.
Electric combi boiler costs
Electric combi boilers heat water by using electricity. As there’s no gas pipe or flue to connect them, they’re typically smaller, quieter, and easier to install than a traditional gas boiler.
They are better for the earth. A combi boiler with an electric heating element can be a better choice than gas. Many units have a minimum of 99% efficiency. You’ll receive a nearly identical transfer of electricity to heat.
These are just a few of the many benefits electric combi boilers can provide. You should be aware that power outages can cause reduced hot water and heating availability. Electric boilers can have higher running costs, which we’ll discuss below.
The average cost of starting an electric combi boiler is £1,100.
Costs of running an electric combi boiler
Although these boilers are simple to fix, running an electric combi boiler can be very expensive. A 12kw electric boiler costing £235 per month at 70 hours would be the equivalent of a UK average of £0.28 kWh. A gas boiler would be only £90 per monthly.
It is because electricity is more expensive than gas. Electric boilers have a higher efficiency, which means that you can generate more heat at the same cost. This could mean that heating your home in this manner may actually be more affordable. There are many ways to lower your running costs, including renewable energy sources.
Consider switching to electric because electric combi boilers have lower operating costs than others and are more affordable than traditional fuels.
Oil combi boiler installation cost
A oil combi boiler may be an option to heat your home and water, even if it isn’t connected directly to the main gas/electric network. While they can be more affordable than other heating systems, such as electric boilers or oil boilers for heat, the installation cost of an oil combi boiler can be much higher.
Oil combi boilers offer hot water and central heating upon demand. One system is sufficient without additional storage tanks and cylinders.
A combi boiler might be right for you. Average oil boiler costs are £3,675.
What is the cost of a system boiler installation?
New system boilers cost around £1,300 + tax. This type of boiler is opposite to a combi boiler. System boilers are similar to combi boilers in that they can be fueled by oil, natural gas, or electricity.
System boilers heat your home and supply hot water. These boilers require a mains water supply.
Perhaps you don’t know if you have one. Most homes built before 1960 have a boiler system. A system boiler will need a cylinder to store hot liquid, which is typically located in an airing cabinet.
Here are the average prices for each fuel type if you decide to install a system boiler.
The average price of a new boiler for a gas system is £2,700.
The average price of an oil system boiler replacement is £3,163.

You can also replace/upgrade your boiler system. The price you pay for the boiler will not include the tank.
Many people replace their system boilers with a combi boiler. However, if this is not your intention and you wish to exchange for a more modern model, you will need to pay £1,600+ to get a basic five-year warranty boiler. A new system boiler of high quality will cost you £2,500. Both prices include supply as well as installation.
The pros and cons of installing an automatic boiler
Before you make a decision about whether to purchase a new boiler, consider the benefits and drawbacks of owning one.
Pros
It is smaller than other boilers, and requires no cold water tank.
Are able to provide warm water to multiple taps simultaneously.
Good mains water pressure.
Can be used with solar power.
Cons
Hot water needs to be heated before it can be used so you need to plan ahead about when you will use it.
Combi boilers are more expensive.
The size of your tank will affect how much hot water you get.
Costs of an electric boiler (system boiler).
We have highlighted some great advantages for electric combi boilers in the cost section. These same benefits apply to system boilers.
Installing other fuels is faster and easier than installing gasoline.
Lower maintenance costs
There is no danger of a gas leak.
Reduction of environmental impact
The average cost of an electric system boiler, supply only, costs £1,202. Electric boilers are a significant cost-saving option when compared with the oil and gas system boilers.
Costs of running an electric boiler
As we have shown in the section about electric combi boiler operating costs, although the fuel cost to run an electric boiler can be higher than with other fuel sources, the heat output can offset that cost.
Consider that how your house is designed will impact the amount of heat you pay. Everything from insulation to windows and other factors play a major role. You will also notice a difference in your electric boiler’s running costs if you choose the wrong electricity tariff. Make sure to shop around for a better rate.
A biomass boiler is a boiler that uses wood pellets, not oil or gas. The fuel is sustainable and you can get a substantial discount on your running costs through government funding. The cost to install a biomass boiler may be higher than for other boilers but the fuel costs are significantly lower.
A combi boiler that is oil-fired might cost about £3,675 for supply and installation, at a cost of 6.5p/kWh. Installation and cost for a biomass boiler is around £16,000. However, the fuel cost per kWh for a biomass boiler is 4.11p.
The fuel cost for a biomass boiler per tonne is about £100 for woodchips, £99 for logs, and £200 to pellets.
The average price for a boiler is around £10,000 + VAT. Installing a biomass boiler includes delivery and installation. It costs between £5,000 and £20,000 to install a smaller boiler at home.
The name condensing boilers is derived from the way they maximise energy efficiency. These boilers trap heat in the flue and do not let it go to waste. These boilers can be up to 90% more energy efficient. The condensing boiler price is also not too high.
On a rough average, a condensing boiler would cost around £2,500 + VAT.
The cost of installation will vary depending on the boiler type and your personal circumstances. There are two types to choose from when it comes to condensing heating boilers: combi and regular.
A regular boiler comes with a hot water tank, and can provide heat for large-sized houses. The combi condensing stove, however, doesn’t have a water tank. This makes the boiler smaller, but also means that it can be used in smaller houses or flats.
The average cost of condensing boiler installation for replacing a regular boiler would be £800. There might be plumbing modifications required if you switch from regular boiler to combi. In this case, expect to spend approximately £1,550 on combi condensing boiler installations.
You have the choice of either conventional or heat-only boilers if system and combi boilers do not suit your requirements. These boilers are typically less expensive than other types, but will require installation of hot or cold water tanks.
Conventional boilers heat stored water until it’s ready to use. This is a great option for large homes. The starting price for a new boiler with a conventional boiler is as low as £480. However, your home size and budget will determine the size boiler you need.
There are some boilers that only heat your home. It is essential to choose the right boiler for you.
There are pros and cons to installing a traditional boiler
It is important to understand the benefits and drawbacks of conventional boilers before you decide whether it is the right option for your needs.
Pros
It is an excellent way to heat water for multiple taps or showers.
Easy maintenance
If mains pressure drops, hot water will still be available
An immersion heater is a device that ensures hot water supplies continue even if the boiler fails.
Cons
Boilers that require hot or cold feed tanks take up more space.
It doesn’t always provide the best pressure for showers.
They are less efficient than the other options. Heat loss can occur when water is left unused for too long.
Hot water may be out of stock during peak demand.
If your boiler has been in use for a while, you may be wondering when it is time to replace it.
These are the signs that you should have a new boiler.
It is possible for repairs to cost more than installing a new boiler. You should consider replacing your boiler entirely if the cost of your boiler repair estimate is very high.
It’s not enough: A new boiler may be needed if your current boiler takes too long to heat water or doesn’t heat fast enough for your family. This is a sign that your older boiler can’t keep pace with the demands.
Low energy efficiency: Your boiler may be consuming too much power to heat a small area. It’s time for you to replace it. This can be a major factor in selling your house. A higher efficiency rating will help you get a better price. A new boiler can bring value to your house.
Old age: Most boilers last around 10-15 years. If your boiler is over 10 years, you can bet you will spend more to replace it than to repair. It will also make it less efficient in heating. At this point it is time to replace the boiler. Modern boilers are a vast improvement over the past 10 to15 years. New boilers will amaze you with their efficiency, performance, and smart tech.
It is also important to be able to access your boiler’s location. It may be necessary to relocate your boiler if it is not possible due to its location. You should replace your boiler with a modern model if you have any of the following points in mind while you are moving. Why? Because the newer models are smaller than older ones and will take up less space. If you have your boiler in the kitchen and your water tank on your landing, you may find that a new boiler will allow you to free up space for storage.
Are you convinced that you need a boiler replacement? You might be wondering what the benefits would be. Let’s take a look at some of the benefits.
Energy efficiency: New boilers will have higher energy efficiency. Heating your boiler will be easier with less energy. That means you’ll have a more environmentally-friendly home. Modern boilers heat water only when it is hot. The result is an environment-friendly home. Bliss.
Lower heating bills: Higher efficiency equals lower heating bills. You’ll be able to save on your heating bills because your boiler won’t heat as much.
You will have a quieter home. Boilers get noisier as they age. A new boiler will make your home more peaceful.
There is more space than older boilers. New boilers on the other side are smaller and more efficient. With a new boiler, you will have more room in your boiler cabinet. You may be able to move your boiler completely, and then free up the cupboard.
Perfect temperature control: New boilers have a higher degree of reliability than older boilers in regulating the right temperature. They are also more accurate and heat up faster.
You get a better property value: The energy rating can affect the property’s value. You’ll have a better energy rating if you buy a new boiler. This will result in a higher property value.
An old boiler may not be suitable for your home if it isn’t efficient. It might be worth considering a replacement for your boiler, which might not be possible with some models. The cost and installation of a conversion to another boiler is the same as installing a new boiler.
Converting your boiler will likely return your money in reduced energy costs and improved heating over the long term.
