020 7458 4949Book a SurveyWhy London flats are going electric
Electric boilers are increasingly popular across prime London — particularly in leasehold flats where flue routes are restricted or impossible, and in properties looking to decarbonise their heating without installing a heat pump.
With no combustion, no flue and no gas safety certification required, electric boilers are simpler to install, quieter in operation and require less ongoing maintenance. Running costs are higher per kWh than gas, but for well-insulated flats with modest heat demand, the total cost of ownership can be comparable — and they future-proof your property against evolving gas regulations.
