What affects the cost of a new boiler?
Every home is different, which is why new boiler costs can vary. Different things can impact the cost of a new boiler:
1. Type of boiler
In general, there are four main types of boilers to consider:
- Combi boilers: from £2,200
- The most popular option, a combi boiler, provides heating and hot water on demand without needing a separate cold water tank or hot water cylinder.
- Ideal for: small to medium homes or flats with limited space.
- System boilers: from £2,200
- A system boiler works with a hot water cylinder to store hot water, meaning you can run multiple taps or showers at once without losing pressure.
- Ideal for: larger homes with families or more demanding hot water needs.
- Conventional boilers: from £2,200
- Conventional boilers are a traditional option, often found in older homes, and require both a cold water tank and a hot water cylinder.
- Ideal for: large homes with high hot water demand or areas with low water pressure.
- Electric / biomass / oil boilers: from £4,000
- In general, electric boilers cost less to install than other types, however have higher running costs since electricity is more expensive than gas in parts of the UK.
- Ideal for: homes without access to gas or those looking for a greener option.
2. Property size
The size of your home, be it a house, a flat or anything in between, will determine which boiler size you need:
- Small homes, flats: require a smaller system with a lower kilowatt output.
- Larger homes, detached houses: require a higher output to meet high demands and hot water requirements.
3. Complexity of boiler installation
The intricacy of your new boiler installation can have an impact on your boiler replacement costs:
- Sticking with the same kind of boiler you currently have should be a reasonably simple job, e.g. trading out an old combi boiler for a new combi model.
- Converting from one type of boiler to another can be a more complex job, e.g. switching from a system boiler to a combi boiler. This can require pipework or cold water tank removals that can incur an extra cost.
- Relocating your new boiler can also result in increased costs due to additional time and resources required.
4. Boiler brand
Our team of Gas Safe registered engineers work with a number of leading boiler brands including Worcester Bosch, Vaillant and Ideal, each offering a range of unique benefits. Unsure which brand is for you? We’ll recommend the best brand for your requirements, whether that’s a Worcester Bosch boiler or a new combi boiler by Ideal.

- ECO4 Scheme: aiming to tackle fuel poverty and reduce carbon emissions.
Who it’s for: homeowners and private tenants in properties with EPC ratings of D, E, F or G who claim income-related benefits. Local Authority Flexibility is also an option via ECO4 Flex for those in low-income or vulnerable households. - Home Energy Scotland Grant and Loan Scheme: up to £7,500 (£9,000 in rural areas), an interest-free loan, or a combination of both towards energy-efficient home improvements and clean heating systems that can help reduce your energy bills.
Who it’s for: homeowners with an existing property located in Scotland that is their only or primary private residence.

Frequently asked boiler cost questions
How much does a new boiler cost?
New boiler costs can begin at £2,200.
The cost of a new boiler can vary depending on:
- boiler type, e.g. gas boiler, system boiler or combi boiler
- boiler installation complexity
- boiler brand
- property size
How long is the warranty on a new boiler?
A new boiler installed by James Frew has a warranty of up to 10 years for total peace of mind.
What are the running costs of a new boiler?
The running costs of your new boiler will vary depending on brand, boiler model and usage.
Gas boilers generally have lower running costs than biomass boilers or electric boilers, since gas prices are currently lower than oil or electricity.
This will fluctuate depending on the current price of each energy source.
What is the most energy-efficient boiler type?
Any new boiler should provide a more efficient energy output than an old boiler; however, modern ‘condensing’ A-rated boilers are generally classed as the most energy-efficient type of boiler.
Additional smart energy solutions, including heating controls, solar panels and air source heat pumps, can help to cut energy bills with efficient ways to upgrade your home heating system.
Do I need a replacement boiler or just a repair?
Some issues with your heating system can be corrected with a simple repair; however, if your boiler is over 10 years old or is often breaking down, boiler replacement costs may end up being less than the cost of ongoing repairs and fixes.
Old boilers are often less efficient than newer boiler models, meaning a replacement boiler may save you more in the long run, especially with ongoing running costs.
