About us
Built for a decision you only make once a decade
London Boiler Replacement exists for the moment you realise your boiler needs replacing. We built the company around an honest process — a free survey before anything is recommended, a fixed price in writing, and a fully Gas Safe registered installation.
What we do in London
We install new boilers across London — free in-home survey first, a fixed written quote, then a fully Gas Safe registered installation, commissioned to the manufacturer's Benchmark checklist.
Around that core sit the jobs that follow naturally: old boiler removal and disposal, and central heating upgrades — smart controls, TRVs and power flushing — where the survey shows they'll actually help.
We cover all 33 London boroughs. Not as a slogan — the borough pages describe how each area's housing stock actually affects boiler choice, because knowing that before we arrive is part of the job.
What we promise
- Free in-home survey, no obligation
- Fixed, written quote agreed before we start
- Fully Gas Safe registered engineers on every job
- Combi, system or regular — recommended honestly
- Old boiler removed and disposed of responsibly
- Straight answers if the survey finds extra work is needed
How we work
A free survey, not a phone guess
We state an honest recommendation only after an engineer has actually seen the property — not a boiler type or price guessed over the phone.
Sized properly, not sold by default
Combi, system or regular — recommended on merit for your radiators, bathrooms and hot water demand, not whichever is easiest to fit.
A fixed quote, agreed before we start
The written price you accept after the survey is what ends up on the invoice — no surprise multiplier once work is under way.
Paperwork that protects your warranty
Every installation is commissioned to the manufacturer's Benchmark checklist and notified through the Gas Safe scheme.

About LBR — FAQs
Is the survey really free?
Yes — the in-home survey is free and comes with no obligation to proceed. You only pay if you accept the fixed quote that follows.
Do you cover all of London?
Yes — all 33 Greater London boroughs. See our areas hub for local pages, or contact us with your postcode to arrange a survey.
How do you decide which boiler type to recommend?
Based on what the survey finds — bathroom count, hot water demand, available space and mains pressure — not by defaulting to whichever is easiest to fit. See our combi vs. system vs. regular guide.
Is your quote really fixed?
Yes. The price agreed in writing after the survey is the price you pay, with no hidden extras added once work has started.
Are your engineers definitely Gas Safe registered?
Yes — every installation is carried out by a fully Gas Safe registered engineer, a legal requirement for gas work in the UK. You can verify any engineer's registration on the Gas Safe Register.
