Looking for the best plumber in Guildford? This guide ranks every plumber we found on Google Maps with a Guildford-area postcode, using Google's own star ratings and review counts rather than anyone's opinion.
We found 40 plumbers and heating engineers with a Guildford postcode (GU1 to GU4), across Guildford town centre, Burpham, Merrow, Stoughton, Onslow Village, Shalford, Worplesdon and Park Barn. For each one we pulled the live Google rating and review count, and the things customers mention most in their reviews. Every number is correct at the time of writing (10 October 2026).
How we ranked them: highest Google star rating first, with ties broken by number of reviews. Places with fewer than 20 reviews go after the rest, because a handful of five-star reviews isn’t a fair comparison with hundreds.
