SGPH — Specialist Gas Plumbing & Heating — is a professional plumbing and heating company serving London and the surrounding counties. We combine genuine trade expertise with the standards and systems of a professional services company.
SGPH was founded with one goal: to bring a higher standard of professionalism to plumbing and heating services in London. We believe tradespeople should operate with the same rigour and accountability as any other professional service.
Our engineers are City & Guilds qualified — the highest nationally recognised standard in the trade. We hold ISO 9001 certification for quality management and ISO 45001 for health and safety. These aren't just badges. They mean our processes are documented, independently audited, and consistently applied on every job we do.
We operate across all London boroughs and the surrounding counties — Hertfordshire, Essex, Bedfordshire and Buckinghamshire — for both domestic and commercial customers.
Your time matters. We give a realistic arrival window and keep you updated if anything changes. No waiting all day for an engineer who doesn't call.
You'll always know the price before any work begins. We stick to what we quote. If the scope changes, we discuss it with you first.
Our engineers clean up after themselves. We use dust sheets, wear boot covers where appropriate, and leave the work area as we found it.
Every job carries a 12-month guarantee on parts and labour. If something we've done isn't right, we come back and fix it. No quibbles.
Qualified, insured engineers. Honest pricing. 12-month guarantee on all work.
