Boiler Installation — London & South East
Advance Plumbing provides Gas Safe certified boiler installation across Greater London and the South East, covering all property types from compact London flats to large commercial buildings and country houses in the Home Counties.
London's diverse housing stock — Victorian terraces, Edwardian semis, post-war blocks, and modern new-builds — presents a wide variety of boiler installation scenarios. Our engineers are experienced across all of these, including properties with limited flue routes, unconventional heating system configurations, and landlord-managed rental properties requiring minimal disruption.
We are manufacturer-accredited with Worcester Bosch and Viessmann, allowing us to offer extended warranties of up to 10 years on new boiler installations. All installations include Building Regulations notification and a Benchmark commissioning certificate.
For South East homeowners and landlords, we offer finance options on new boiler installations — allowing the cost to be spread over monthly payments without delaying a necessary replacement.
