Why it matters who touches your gas

Qualified, accountable, and on the register you can check.

Gas Safe registration is the law for a reason. Behind that number is real training, real insurance, and a person who is accountable for the work in your home.

Trained the right way

British Gas apprenticeship, then 11 years as a British Gas gas technician before going independent.

Fully insured & DBS checked

Public liability cover and an enhanced DBS check, so you can let me in with complete confidence.

12-month workmanship guarantee

Every job is backed for a full year. If something I touched isn’t right, I come back and put it right.

Companies House registered

Gas Champion Ltd, company #11731061. A proper business that stands behind its name.

What I do

Natural gas heating, done thoroughly.

From a quick breakdown fix to a full new boiler. Natural gas only, no oil or LPG, and never a job rushed.

    Boiler not working?

    Before you call anyone, run through a few simple checks. Sometimes it’s a reset, a pressure top-up or a tripped switch.

    Power flushing & system care

    This is what hides inside a sludged-up system: cold radiators, noisy boilers and shortened life. A proper flush and a good filter, and your heating runs clean and quiet again. Ask about power flushing, filters, thermostats and controls.

How I work

No mystery, no mess, no surprises on the bill.

The bits that make the difference between a tradesman you tolerate and one you keep the number for.

  1. 01

    2-hour arrival windows

    Your day is yours. I give a tight window rather than a vague morning or afternoon, so you’re not waiting in all day.

  2. 02

    Live “on my way” tracking

    GPS tracking so you can see me coming and time things around your day, not mine.

  3. 03

    Diagnose before any major work

    I find out what’s actually wrong and quote it before committing you to anything big. No guessing with your money.

  4. 04

    Same-day digital certificates

    Your gas safety record emailed the same day, properly filled in, ready to forward to a tenant or letting agent.

  5. 05

    Upfront, transparent pricing

    You hear the price before the work, not after. Card, Apple Pay, Google Pay or bank transfer, whatever suits you.

  6. 06

    Left cleaner than I found it

    Dust sheets down, mess cleared, old parts taken away. You shouldn’t know I’ve been, apart from the heating working.
