Generally speaking, electric boilers cost roughly the same as gas boilers in terms of upfront and maintenance costs. You can find electric combi boilers in the UK for as low as £900, and regular electric boilers can even go down to £500. Usually, prices go up to around £2,500, however, some premium models can cost more. Below we’ve put together a table of what you can expect the electric combi boiler cost to be:

Of course, when it comes to the total cost of an electric boiler you’ll also need to consider the running costs and installation costs.

Before finding out which electric boiler in the UK is the best, you may be curious as to what exactly an electric boiler is and how it works.

The difference between electric vs gas boilers is minimal – an electric boiler works in exactly the same way as a gas boiler, but uses electricity as its fuel rather than gas. This means it does not directly produce any carbon emissions, and that there is no health risk with having one installed.

As you may already be aware, gas boilers are generally available in 3 different types: combi, system and regular/conventional. This is no different for electric boilers. This means that, whether your home is best suited to a regular, system or combination boiler, there will still be plenty of electric boilers in the UK for you to choose from.

Designed to provide heating and hot running water to a property, directly from the mains water supply, combi boilers are the most popular boiler type in Britain. It’s no surprise then, that there are many different electric combi boilers already available on the market.

However, electric combi boilers are not all the same. That’s why we have provided some electric combi boiler reviews below to give you an overview of some of the best boilers on the market:

The latest addition to the Electric Heating Company’s boiler portfolio, the Mercury combi boiler is available in a wide range of outputs to suit different property sizes, and sports some state of the art features too.

The only drawback of this electric combi boiler is that the models with lower outputs are not capable of producing a high enough flow rate of hot water to efficiently fill a hot bath, and are only recommended for use with showers.

A boiler type that’s becoming less and less common, regular boilers require a separate hot water cylinder to provide hot running water, and a feed tank in the loft to provide a water supply. This boiler type requires a lot more pipework compared to other types of boilers, such as an electric hot water boiler. However, if you already have the existing pipework, an electric regular boiler could be fitted with little hassle.

We’ve provided some information on what we consider to be the best electric regular boiler below.

A lightweight and compact regular boiler that’s made in the UK, the Amptec regular boiler is available in 5 output sizes and can be used with pressurised or open-vented systems. We’ve listed some of its key features below.

As this electric boiler is only available in lower output sizes, it is unfortunately not suitable for larger properties with high hot water demands.

A cross between combi and regular boilers, system boilers are best suited to homes with higher demand for hot running water. They require a hot water storage cylinder to provide hot running water, but draw their water supply directly from the water mains.

As electric boilers are generally only available in lower output sizes, system models are actually quite common. This is because a separate hot water cylinder can store hot water that can then be drawn by the hot taps or a shower.

We have provided some details about what we consider to be the best electric system boiler below.

The Mattira range of boilers from Elnur is the only range of boilers capable of regulating energy consumption according to the heating needs of the property. They do this by measuring the internal and external temperatures of the property every 20 seconds. We have listed some further key features below.

While this system boiler is capable of meeting high hot water demands of a home, it is limited to how many radiators it can support, and would not be suitable for a large home.

If you are unsure of which type of boiler to get, but still want to make the move to an electric boiler, we recommend getting advice from a qualified heating engineer. They can help you with deciding on what’s best for your home and take the hassle out of doing the research on your own.

To ensure you are getting the best advice, and not overpaying on boiler installation, we also recommend comparing quotes from several heating engineers near you. That way you can compare the different quotes, and have the peace of mind that you’ve got the best deal. This is something we can help with.

Depending on the size of your property and how many radiators you have, you will need an electric boiler of a specific output size. A good way to work out what output size would be suitable for your home is to allow for 1.5 - 2kW for each radiator in the property.

As electric boilers are only available in a limited range of output sizes, they are more suited to small to medium sized properties.

As a typical flat will have very few radiators throughout the property, any kind of electric boiler would be able to meet its heating and hot water requirements easily. The main consideration for what would be suitable, will most likely be more about space.

As the Heatrae Sadia Amptec has very compact dimensions, it could be a good choice. However, you need to take into account that it would require a separate hot water cylinder to provide hot running water. Which would take up a lot of space itself.

If your flat is already fitted with a combi boiler, replacing it with the Mercury electric combi boiler could be a good option. It will easily fulfil your heating and hot water needs, and can help to lower your carbon footprint too. Especially if your energy supplier provides electricity from renewable sources.

If your flat requires an electric boiler for hot water only, then it might be worth considering an electric immersion heater or water heater for your home instead.

To be completely honest, it’s difficult to recommend the best electric boiler for a large house. This is because their output sizes are limited by the electrics within a property. To successfully power an electric boiler with an output size higher than 12 - 15kW you will need to have a 3-phase electric system.

Add to this the fact that an electric boiler will struggle to provide sufficient amounts of domestic hot water to a large property, and it becomes clear that your best option will not be an electric boiler.

There are other low carbon heating alternatives that could heat a large home effectively though. One of which is an air source heat pump in the UK.

While electric boilers are not the only renewable alternatives to gas or oil boilers, they do have many benefits that are not provided by other renewable options.

Unfortunately, where there are advantages, electric boilers do have a few disadvantages too.

As there are considerably fewer disadvantages than advantages when using an electric boiler, it’s no surprise that many British homeowners are choosing them.

If you are considering getting an electric boiler and want to ensure you find one at the best possible price, we highly recommend getting quotes from multiple heating engineers near you. This allows you to compare the quotes against each other, understand which engineer is offering you the best deal, and avoid being overcharged for the installation. This is something we can help with.
