02Powerflushing

Clear the sludge. Feel the difference.

A power flush gives your central heating a thorough internal clean, usually improving its performance — which can lead to lower gas bills and extend the lifespan of your boiler.

  • Lukewarm radiators
  • Poor hot water
  • Increased noise
  • Sludge build-up

We flush your system in different directions, using special chemicals to break down sludge, iron filings and debris, then remove it via inline magnetic filtration.

03Boiler servicing

Safe, efficient, warranty-ready.

Manufacturers recommend an annual service — and if your boiler is under warranty, you need one to keep it valid. Every Heat GB service includes:

  • Visual check against current standards
  • Boiler fired to identify working faults
  • Burner, heat exchanger, injector & probe checked
  • Gas safety devices checked
  • Flue terminals & seals inspected
  • Combustion tested with a flue gas analyser
  • Casing & parts cleaned
  • Gas tightness test

04Boiler & heating repairs

Temperamental heating? Sorted.

It doesn’t necessarily mean a whole new system is required. Our engineers have previously worked directly for boiler manufacturers and have in-depth knowledge of faults across a range of boilers.

We’ll quickly diagnose and repair your boiler where viable, using quality components and parts — and advise on the best way to get your heating back to its maximum potential.

05Landlord gas safety (CP12)

Legally safe, every 12 months.

A Landlords Gas Safety Inspection Certificate (CP12) is required by law every 12 months, issued by a Gas Safe registered engineer. It confirms all gas appliances and installations work lawfully and within normal parameters at the time of inspection.

We carry out inspections on behalf of landlords and letting agents, and keep your appliances regularly maintained and in good working order.
