Coalpit Heath HQ 26+ years experience

Who we are

Independent. Locally trusted. Over 26 years of experience.

GT Bathrooms & Boilers was founded by Gary Tweedie in Coalpit Heath, with over 26 years of experience behind him. Today we're a small, independent team of Gas Safe registered engineers, Worcester Bosch accredited installers and in-house tradespeople, all working out of two showrooms in Bristol and central Bath.

We don't use subcontractors. Plumbing, gas, electrics, tiling and making good are all handled by the same team, so the engineer who arrives on day one is the one who hands you the keys on day three.

Common questions

Got a question? Start here.

If your question isn't covered, just call or message us.

How much does a new boiler installation cost?

New boiler installations start from £1,950 plus VAT, fully fitted. Final cost depends on the boiler model, the complexity of the install, and any system upgrades you need. We provide a free home visit and a written quotation by email, with no obligation.

How long does a boiler installation take?

A straight swap usually takes a single day. If we're relocating the boiler or making major changes to the system, it can take two to three days. We'll give you a clear timescale in your quotation.

Are your engineers Gas Safe registered?

Yes, every one of our heating engineers is fully qualified and Gas Safe registered. We're also Worcester Bosch accredited installers and Which? Trusted Traders.

What guarantee comes with a new boiler?

As Worcester Bosch accredited installers we can offer up to a 12 year manufacturer guarantee on new Worcester boilers, subject to terms and annual servicing. All our installation work is also covered by our own guarantee.

Do you cover my area?

We cover Bristol, Bath and the surrounding areas including Coalpit Heath, Yate, Thornbury, Portishead, Clevedon, Weston-Super-Mare, Bradford-on-Avon, Corsham, Radstock and Saltford. If you're nearby, give us a call to confirm.

What happens to my old boiler?

We take it away and dispose of it responsibly. The cost of removal is always included in your installation quote, no extra fee.

Do you offer finance options?

We don't currently offer in-house finance, but we can talk you through payment plans for the larger installations during your free home visit.
