Boiler Types and Costs
The primary factor that affects the cost of a new boiler installation is the type of boiler and kw you choose. There are three primary types commonly found in London households:
a) Combi Boilers: Combination boilers or combi boilers provide both hot water and heating without the need for a separate water storage tank. Combi boilers tend to be the most popular choice in London due to their compact size and efficiency. The cost of a new combi boiler installation typically ranges from £1,700 to £4000.
b) System Boilers: System boilers require a separate hot water cylinder but offer a higher water flow rate. This makes them suitable for homes with multiple bathrooms. The cost of installing a system boiler in London generally falls between £2000 and £3,500.
c) Regular Boilers: Regular boilers also known as conventional or heat-only boilers are typically found in older properties with traditional heating systems. These boilers require a separate hot water cylinder and cold-water storage tank. The cost of a regular boiler installation in London can range from £2,000 to £4,500.

Boiler Size and Output
The size and output of a boiler play a significant role in determining its cost. The size of your property, its heating requirements, and the number of bathrooms will influence the boiler’s size. A larger property with higher hot water demands will require a more powerful and costly boiler. It is crucial to consult with a qualified heating engineer to determine the appropriate boiler size for your specific needs.
Efficiency Ratings
Boilers are assigned energy efficiency ratings known as SEER (Seasonal Energy Efficiency Ratio) or ErP (Energy-related Products). Higher-rated boilers are typically more expensive up front, but they can save you money over time by using less energy and costing less to operate. Investing in a highly efficient boiler can help offset the initial installation cost through long-term energy savings.

Additional Installation Costs
In addition to the boiler itself there are several other costs associated with a new boiler installation:
a) Pipework and Radiators: Depending on the condition of your existing heating system you may need to update or replace pipework and radiators. These costs can vary depending on the installation requirements and the amount of radiators required.
b) Controls and Thermostats: Upgrading your heating controls and thermostats can enhance the efficiency of your new boiler. These additional components may come at an extra cost but can provide greater control over your heating system.
c) Flue and Ventilation: The installation of a new boiler requires a new flue system for safe ventilation. The complexity of the flue installation, such as routing through walls or roofs, can impact the overall cost.
d) Power Flushing: If your existing heating system suffers from sludge and debris build up, a power flush may be necessary before installing a new boiler. Power flushing helps improve efficiency and ensures the longevity of your new heating system.

Installation and Labour Costs
The cost of a new boiler installation with labour will vary depending on the complexity of the job. The location and specific requirements for the new boiler installation will have an impact on the cost. Materials required ie copper will also impact the overall price. It is best practice to use a reputable heating company with experience in boiler installations to ensure the installation is quoted for correctly.
