Why Grant's Plumbing and Heating?
Most boiler companies send a salesperson. We send a genuine Gas Safe engineer.
Most give vague estimates. We give fixed prices.
Most upsell. We install properly and leave.
Grant's Plumbing and Heating was built to take the sales pressure out of boiler installs. Fixed price. Transparent. Done properly. A small, family-run team of local Gas Safe engineers.
