Different types of boilers and their costs<\/em><\/figcaption><\/figure>\n\n\n\n
<\/div>\n\n\n\n

Is your boiler old, broken, out of warranty, or simply not working as well as it used to? This might be a sign that it\u2019s time for a new boiler. Whatever the reason, a new boiler comes with lots of benefits.<\/p>\n\n\n\n

For starters, old boilers have a much lower efficiency percentage than more modern models. This means that, over time, a new boiler will save you money by reducing your energy bills. Since heating and hot water make up over half of your yearly energy bill, a very efficient boiler is a worthy investment.<\/p>\n\n\n\n

A new boiler will also cut your carbon footprint. Upgrading appliances to more eco-friendly and energy-efficient models<\/a> is an incredibly worthwhile home improvement, because it can also increase the value of your property.<\/p>\n\n\n

\n
\"Picture<\/figure>\n<\/div>\n\n\n

On average, a new boiler installation will cost you between \u00a32,500 <\/strong>and \u00a33,500<\/strong>.<\/p>\n\n\n\n

The prices in this guide will always clarify where a sum includes cost of labour and<\/strong> materials, and where the price is referring to them separately. Lastly, the prices in this guide do not<\/strong> <\/em>include VAT. <\/p>\n\n\n\n

How do you know when your boiler needs replacing?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n
\"Broken<\/figure>\n\n\n

It\u2019s time to change your boiler when it becomes more cost-efficient to replace it than to keep repairing it in the short-term, as repairs can get expensive. <\/p>\n\n\n

A warning sign that you might need a new boiler is rising energy bills, despite you using your boiler the same amount as before.<\/p>\n\n\n

Boilers tend to have a lifespan of around 10 years. If yours is around that age, and is starting to show signs of wear, then it might be time to replace your boiler. Since older models are less efficient, costing you more in energy bills, replacing yours is definitely worth it.<\/p>\n\n\n\n\n\n\n\n\n

What boiler should I get?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n
\"Picture<\/figure>\n\n\n

By law, all modern boilers are now condensing boilers, which have a 90% efficiency rate. But there are still a wide range of options for you to choose from. <\/p>\n\n\n

Which boiler you go for will depend on a few factors, including how much space you have, since some types, like combi boilers, are better suited for smaller houses with no space for large water tanks.<\/p>\n\n\n

It\u2019s also cheaper to install the same type of boiler that you already have, and it usually makes sense to stick to the same type (since it\u2019s normally the right kind for your house). However, in some cases it makes sense to change boiler types. This guide includes the pros and cons of a range of different boilers, as well as how much it would cost you to buy and install each in your home.<\/p>\n\n\n

Picking the right boiler<\/a> is important, as it needs to be efficient enough to supply hot water to your entire home, whilst not wasting energy or leading to huge fuel bills either.

Which fuel is used in boilers?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n

The main types of boiler fuel are oil, gas, LPG, and electricity.<\/p>\n\n\n

Oil fuelled boilers<\/strong><\/td>Gas fuelled boilers <\/strong><\/td>Electric fuelled boilers <\/strong><\/td>LPG fuelled boilers<\/strong><\/td><\/tr>
If your home is not connected to a gas mains, then an oil boiler is a popular alternative to gas. Oil is stored in a tank inside or near your property, where it\u2019s then pumped into a combustion chamber.
<\/td>		Gas boilers are fuelled by natural gas which passes through the gas mains, and is usually used for closed systems. You can get combi, conventional and system boilers that are fuelled by gas.
<\/td>		Electric boilers use electricity to heat your water. Electric boilers pass water through an electric element to heat it, and are a popular alternative for homes not connected to a gas mains.
<\/td>		LPG stands for liquid petroleum gas, and is another good alternative to natural gas. They\u2019re available to purchase in a pre-built format, and require a storage tank, which come in a variety of sizes.
<\/td><\/tr>
Pros:

The main fuel type for people that live off the grid

Modern oil boilers are energy-efficient and easy to replace 




















<\/td>		Pros:

The most popular heating source in the UK

Gas is efficient, affordable and reliable 

One of the cheapest options for fuel

Can be offset by solar panels if you have these installed 

Minimal carbon footprint
<\/td>		Pros:

You can get an LPG conversion kit to easily convert a regular boiler into an LPG one

A large quantity of fuel can be stored in a small space, since LPG is denser as a liquid than as a gas

A good alternative when natural gas can\u2019t be provided

Requires a smaller storage tank than oil

More eco-friendly than oil (12% fewer emissions on average than oil)

Cheaper to install and maintain than oil 


<\/td><\/tr>
Cons:

Oil for the tank has to be ordered in advance so you need to be aware when you\u2019re running low so you don\u2019t run out

Requires a large oil tank that takes up space

Not limited by energy price caps, with rising prices <\/td>		Cons:

Relies on you having a gas mains nearby to connect to and is therefore not available for all homes

Produces a lot of carbon
Risk of carbon monoxide leak 



<\/td>		Cons:

Electric boilers are recommended for small homes as they can only heat a limited amount of water at a time

More expensive, at around 18p per KWh, that can rise to 25-28p per kWh depending on location
<\/td>		Cons:

More expensive than oil in the long term

Being phased out of new builds by 2025

There are less qualified engineers to install LPG

How much does a heating engineer charge to install a boiler?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n
\"Picture<\/figure>\n\n\n

On average, a heating engineer will charge a rate of between \u00a360 <\/strong>and \u00a3180 <\/strong>an hour, though this will vary depending on who you hire, and where you live in the UK. <\/p>\n\n\n

It usually takes between half a day and a full day to install a boiler, averaging out to anywhere between \u00a3500 <\/strong>and \u00a31,000 <\/strong>for an installation (not including the cost of your boiler). If you also need a Powerflush, then this will take an additional day. In some instances, an installation might cost upwards of \u00a31,500,<\/strong> depending on the specific requirements of your installation.<\/p>\n\n\n

How much does a new system boiler cost?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n

On average, a new system boiler will cost you between <\/em>\u00a32,500 <\/em><\/strong>and <\/em>\u00a34,000.<\/em><\/strong><\/p>\n\n\n

System boilers are made up of two parts, the boiler itself, that heats your water, and a cylinder that stores it.<\/p>\n\n\n

They\u2019re great for households with multiple bathrooms where hot water is needed by several people at the same time. This is because they can run fast, high-pressure hot water from multiple taps.<\/p>\n\n\n

Usually, your system boiler fits in a small cupboard, whilst the cylinder sits in an airing cupboard. Normally, all the parts of a system boiler are fitted into a single unit, making them really easy and quick to install.<\/p>\n\n\n

Though they offer on-demand hot water, this depends on how big your cylinder is. You may also need to buy storage for your cylinder. <\/p>\n\n\n

This price can be affected by the brand you choose for your boiler, how long the warranty is for it, and whether the installation will require additional costs such as condense pumps or valves.<\/p>\n\n\n

Pros of a system boiler<\/strong><\/td>Cons of a system boiler<\/strong><\/td><\/tr>
Can supply hot water to multiple taps faster and without affecting pressure

Don\u2019t require a cold water tank like conventional boilers do, saving space

Easier to install than conventional boilers (all components built into one unit)
<\/td>		Hot water is heated in advance, so you need to know in advance when you will need it

Amount of hot water depends on cylinder size 

You need to make sure your boiler is well insulated, or it will lose heat

You will need to buy storage for the cylinder <\/td><\/tr><\/tbody><\/table>

How much does a traditional boiler cost?<\/strong><\/h3>\n\n\n
 <\/a><\/div>\n\n\n

The average cost of a new, conventional boiler is around <\/em>\u00a32,800, <\/em><\/strong>or anywhere between <\/em>\u00a32,100 <\/em><\/strong>and <\/em>\u00a33,600. <\/em><\/strong>How much you end up spending will be determined by the type of boiler you buy and the intricacies of the installation, as well as your location in the UK.<\/em><\/p>\n\n\n

Traditional, or conventional boilers, get their name from being the oldest type of boiler still regularly sold in the UK.<\/p>\n\n\n

They need both a cold water tank, normally stored in a basement or loft, as well as a hot water cylinder in an airing cupboard. This means they take up lots of space. However, their water pressure is great, and they\u2019re good at supplying hot water to your whole house at the same time.<\/p>\n\n\n

They\u2019re also compatible with energy-efficient options like solar thermal systems. However, they\u2019re less efficient than other types of boilers if you don\u2019t insulate the cylinder well.<\/p>\n\n\n

Pros of a traditional boiler <\/td>Cons of a traditional boiler<\/td><\/tr>
If you already have a traditional boiler, replacing one is easy, requiring only a little pipework

Hot water can run from multiple taps, quickly and with high water pressure

Compatible with energy-efficient options 

Good for houses that have low water pressure

Easy to maintain <\/td>		You will need to install an immersion heater if you want to make sure you\u2019ll still have hot water if the boiler breaks down

Take up lots of space

More expensive to install 

Hot water limited to the size of your cylinder

The average cost of a new combi boiler installation is between <\/em>\u00a32,850 <\/em><\/strong>and <\/em>\u00a33,500.<\/em><\/strong><\/p>\n\n\n

Combi boilers, short for combination boilers, are the most popular type of boilers sold in the UK. <\/p>\n\n\n

They control both the central heating, and the hot water in your home, by heating water directly from your mains rather than storing hot water inside a tank. This means that they\u2019re fairly compact to install, and have no limit when it comes to how much hot water they can provide.<\/p>\n\n\n

The other great thing about combi boilers is that they can help you reduce your carbon footprint. They have a high energy efficiency and are cost-effective because they only heat the water you need at any given point during the day.<\/p>\n\n\n

However, the water pressure can weaken if you run more than one water source at the same time. If your combi boiler broke down, it would leave you without hot water, as it doesn\u2019t have a backup source unless you also have an immersion heater installed.<\/p>\n\n\n

Expect to pay more if you live in London or the South East.<\/p>\n\n\n

Pros of a combi boiler<\/strong><\/td>Cons of a combi boiler<\/strong><\/td><\/tr>

Biomass boilers are also called wood boilers because they run by burning sustainably sourced wood pellets. They\u2019re the most affordable way to generate heat, so they can save you money in the long run. They\u2019re also carbon neutral, making them a great, eco-friendly heating solution.<\/p>\n\n\n

They’re more expensive to fit, and also have additional costs, like wood delivery service fees. However, because biomass boilers are eco-friendly, the government offers money back through the Renewable Heat Incentive Scheme<\/a>, to encourage homeowners to buy one, making fuel costs much lower.<\/p>\n\n\n

This means that, although it costs more to install them, they do save money in the long run.<\/p>\n\n\n

On average, a biomass boiler will cost you \u00a315,500 <\/strong>to buy and install. That\u2019s around \u00a310,500 <\/strong>for the boiler itself (between \u00a37,200 <\/strong>and \u00a312,500<\/strong>), and around \u00a33,000 <\/strong>to \u00a35,000 <\/strong>for the installation.<\/p>\n\n\n

Prices are also affected by whether you want a manually fed biomass boiler, or an automatically fed boiler. A small (15kW), manual fed log boiler could cost as little as \u00a34,000 <\/strong>(materials only), whereas large (up to 1000kW) automatically fed pellet boilers can cost upwards of \u00a325,000. <\/strong>Tell us what you need, and get a free quote today. <\/p>\n\n\n

     <\/a><\/div>\n\n\n
    \"Picture<\/figure>\n\n\n

    The below are some tips to help you save money on your new boiler installation:<\/p>\n\n\n

      \n\n
    1. Always ask for multiple quotes before you make a choice on what boiler you want to buy, and who you want installing it. It\u2019s a good idea to have a sense of how much a new boiler could cost you (upper and lower ranges) so that you can feel confident that you\u2019re getting your money\u2019s worth.<\/li>\n\n\n
    2. Make sure you have a clear idea of what is included in your package – hidden extras can bring up prices, so make sure the quote you get includes the cost of the boiler, installation, and any add-ons you might want, such as a smart thermostat, old boiler removal, and a system filter and cleanse.<\/li>\n\n\n
    3. Know what size boiler you need for the size and number of inhabitants of your household. This will avoid you paying for energy that you\u2019ll only end up wasting. The below guide should help give you a sense of what size boiler you should get.<\/li>\n\n\n
    4. Buy a trusted brand – a good quality, reliable boiler may cost you a bit more up front, but it will definitely save you money in the long term. You\u2019re better off spending money on a good boiler rather than on boiler repairs every time yours breaks down. Look out for boilers that come with a long warranty – this is usually a good sign that a product is likely to last without problems. <\/li>\n\n\n
    5. You don\u2019t have to buy a boiler from your energy provider. They\u2019re often more expensive, and you will be pressured into buying on the same day to avoid you shopping around for cheaper alternatives.<\/li>\n\n<\/ol>\n\n\n\n\n\n\n\n\n
