Types of Boilers
When you search for a new boiler by visiting the marketplace or online, you will be overwhelmed with numerous options. But to simplify things for you, I will mention common types of boilers popular among UK residents.
1. Heat-only Boiler
Suitable for larger homes, a heat-only boiler provides hot water and central heating with the help of hot water and a cold-water storage tank. It is a great option for homes with more than three bedrooms, and it requires hot water in multiple bathrooms simultaneously.
The estimated cost of a heat-only or conventional boiler will range between £600 and £3500, and the average cost, including installation, will be £2900.

2. System Boiler
Like heat-only boilers, a system boiler is a popular boiler that is more space-saving as it provides hot water and heating without needing an additional cold water storage tank. The system boiler uses a pressurised heating circuit directly connected to the mains, eliminating the need for a cold-water tank and making it a more popular choice.
The estimated cost of a system boiler ranges between £550 and £3500, and the average cost, including installation, will be £2800.

3. Combi Boilers
A combi-boiler, originally known as a combination boiler, is suitable for smaller homes. It provides heating and hot water without requiring an additional water storage tank, making it a more space-efficient and easy-to-install option. Also, they are ideal for homes with 2–3 bedrooms. Plus, they have a preheat function, which stores a small amount of heated water to supply you instantly.
To know how much a combi boiler costs then to give you an estimate the cost will range between £500 and £3,000, and the average cost, including installation, will be £2800.

Above, I mentioned common types of boilers popular in the UK; however, these boilers work on common fuel types, including gas, oil, and coal. But if you are looking for sustainable practises to limit the emission of harmful gases into the environment, you can also find alternative fuel options for your boiler mentioned below:
4. Electric Boiler
As the name suggests, an electric boiler heats water and provides central heating by using electricity. It is a great option if you are looking to adapt to sustainable practises and reduce your dependence on fossil fuels. Also, electric boilers are very easy to install as they don’t require flue installation or condensate pipe. And talking about energy efficiency, compared to a gas boiler that achieves 70%–90% efficiency, the electric boiler can achieve 99% efficiency.
If your home is off the gas grid, an electric boiler is ideal. Also, electric boilers offer compatibility with solar panels, granting you access to renewable energy sources and saving money on your energy bills.
The estimated cost of an electric boiler ranges between £590 and £2500, and the average cost, including installation, will be £2800.
5. Biomass Boiler
A biomass boiler is another type that utilises renewable energy sources to provide heat and hot water to your home. Working similarly to conventional boilers, they combust fuel to provide you with warmth and hot water. But the catch is that they burn wood pellets instead of using gas or oil to create energy. Although it emits carbon dioxide into the environment, it does so to a very low extent, making it a very environment-friendly option.
Bear in mind that you will need a lot of space to install a biomass boiler, and you will also need an additional room to store wood logs or pellet supplies.
The estimated cost of a biomass boiler ranges between £4000 and £12000, and the average cost, including installation, will be £16000.
Below, I have broken down the cost of a new boiler before and after installation so you can compare and make a more precise decision.

Additional factors that affect the cost of a new boiler
1. Boiler Size
The size of your boiler will affect its cost, as the bigger the size, the higher the price. To determine the ideal size of boiler for your home, you need to determine the following:
- Number of bedrooms
- Number of radiators
- Number of bathrooms
- How well-insulated your home is
2. Boiler Type
After determining the size, you opted to change the type of your boiler due to an increase or decrease in hot water and heating demand. Then, the cost will increase depending on the type of boiler, complex installation, including flue and pipework, and additional labour work.
3. Model and Brand
Now that you have determined the type of boiler, the next step is to choose the model and the manufacturing brand. This will affect the cost of a new boiler due to the brand’s reliability and warranty. Below are some of the top brands, along with the cost of their types of boilers:
|Heat-Only Boiler Price Range
|System Boiler Price Range
|Combi-Boiler Price Range
Note: Installation and labour costs are not included in the above prices because they differ between manufacturers.
4. Fuel Type
Another important factor that you must consider that influences the cost of a boiler is the fuel type. Primarily, you will be choosing among three options:
Choosing a boiler that uses electricity to generate heat and domestic hot water is a great choice if you are not connected to the gas grid and want to lower your carbon footprint. Nowadays, many people are transitioning towards electricity to minimise their dependency on gas.
But most people don’t know that most of the electricity in the UK is generated by burning fossil fuels. Although you will find different variations of electric boilers on the market and you will be saving money and impacting the environment in the long run, the running cost of an electric boiler is more expensive than oil and gas fuel types.
The cost of an electric boiler ranges between £590 and £2500, and the installation cost will range between £1,600 and £3,500.
The most common fuel type that is used for heating and hot water is gas. Gas, being inexpensive, is the most popular fuel type that most UK residents opt for. And if your boiler has higher efficiency ratings, the carbon emissions will also be low.
The cost of a new gas boiler ranges between £2000 and £4000, and the installation lies between £500 and £4000.
Another common but less popular fuel is oil-fueled boilers. It is an ideal choice if you are not connected to your local gas grid and want to avoid the expensive running costs of electric boilers.
The price of a new oil boiler ranges between £999 and £2,800, and the installation and replacement cost will range between £2500 and £4000.
5. Relocating your boiler
If you are looking for a new boiler and a new location for your boiler due to renovation or some other reason, then get ready to bear the additional cost of labour, pipework, fixtures, and fittings.
6. Radiator cost
When buying a new boiler, inspect your home’s heating system in detail, including the radiator. Suppose your radiators are old and worn with time. In that case, you should consider replacing your radiators, as inefficient radiators will affect the performance of your new boiler.
The estimated radiator replacement cost will range between £200 and £400, depending on numerous factors.
7. Magnetic Filter
Whenever a Gas Safe Registered Engineer installs and fits a new boiler, he recommends installing filters. Filters like magnetic filters are installed inline on the pipework to prevent sludge, iron oxides, corrosion, and other dirt particles from entering the boiler. The average cost of boiler magnetic filers ranges between £100-£200.
8. Chemical Flush
A chemical flush is a way to remove dirt particles from your central heating system so that the performance of your new boiler isn’t affected. A hot chemical flush costs around £100-£150, but if your central heating system is old and the build-up of dirt is heavy, making your radiators cold from the bottom and leading to an interrupted flow of heating, then you could opt for a power flush.
9. Upgrading Warranty
Investing in extended warranties is a great way to gain peace of mind regarding uncertain malfunctions or damage to your boiler. Only reputable manufacturer partners offer these warranties, and they are priceless.
How can I avoid the hefty cost of installing a new boiler?
One effective way to avoid the significant expense of purchasing a new boiler is to obtain quotes directly from providers, either by contacting them directly or through online platforms. This approach allows you to gather multiple price options and compare them to select the most suitable one for your specific needs.
Additionally, many providers offer the option of monthly payment plans, enabling you to spread the cost over several years. Moreover, boiler finance options are available, providing you with greater flexibility in managing your expenses.
