Keystone London Group Ltd

Keystone London is a plumbing and heating company serving homeowners, landlords and property managers across West, South West and Central London. With over 15 years of industry experience, our team provides reliable plumbing, heating, boiler and air conditioning services, from everyday repairs and maintenance to larger installations and urgent call-outs. We believe good service goes beyond fixing the immediate problem.

It means arriving prepared, explaining what needs to be done, giving straightforward advice and treating every property with care. Our engineers focus on practical, lasting solutions rather than unnecessary work. With experienced engineers, fully stocked vans and a team that genuinely cares about the quality of its work, we aim to make looking after your property as straightforward as possible.

We combine experienced engineers, straightforward advice and quality workmanship with the personal service you'd expect from a local company. Our principles include putting the customer first, working with only the best people, offering transparent and fair pricing, and ensuring quality as a standard. Every member of our team is fully vetted, insured and DBS checked, and we stand by every job we complete with warranties that go beyond the industry standard.
