Wonersh Boiler Engineer
Gas Safe registered (reg. 554328) — local team covering GU5 and surrounding areas.
Boiler servicing in Wonersh is the single best way to push your boiler past 15 years. Worcester Bosch's own warranty data shows boilers that miss a service in any year fail twice as often within 24 months. We catch the early signs — low gas pressure, drifting flue gas readings, sludge in the filter — that are cheap fixes early and expensive ones late.
Why this matters in Wonersh
Most Wonersh customers stick with the same engineer year after year because they want consistency — the same person who knows your boiler, your system quirks, your filling-loop position. That continuity is genuinely rare in plumbing and it pays back in fewer diagnostic visits.
Usually back to you the same working day across GU5.
Boiler Servicing & Repairs for Wonersh homeowners
Wonersh is mostly owner-occupied family housing — Tudor and Georgian tile-hung cottages, 1930s detached — and our boiler servicing work here reflects that. We're in your home, not a building site, and the install plan we agree at quote stage is the install you get on the day.
Our boiler servicing coverage of Wonersh extends right across GU5 and the surrounding parishes — Bramley (1mi south), Shalford (2mi north), Chilworth (2mi north-east). Waverley Borough Council is the planning authority for any external work like flue routing or condenser placement, and we deal with that paperwork end-to-end.

Boiler Servicing & Repairs in Wonersh — common questions
What's the most common boiler fault you see in Wonersh?+
Pressure drop — three causes, in order: tired filling-loop washer (£40 fix), corroded radiator valve (£90-£150 fix), pinhole in the heat exchanger (£600+ or replace). We diagnose with a pressure-drop test before quoting, so you know which it is. Common across older Tudor and Georgian tile-hung cottages.
Do you do power flushes in Wonersh too?+
Yes — but only when the system actually needs one. We diagnose with thermal imaging and a magnetic filter inspection first. If your filter is empty and rads heat evenly, you don't need a £400 flush and we'll tell you so.
Do you do landlord CP12 gas safety certificates in Wonersh?+
Yes — CP12 certificates emailed to landlord and managing agent the same day the inspection runs. Typically booked inside 48 hours across Wonersh. £79 standalone, or £130 bundled with the annual service.
My Wonersh boiler keeps losing pressure — what does it mean?+
Usually one of three things: a tired filling-loop washer, a corroded radiator valve, or (least often but most expensive) a pinhole in the heat exchanger. We diagnose with a pressure-drop test and tell you which it is before quoting — no "we found this, that's £400 extra" surprises mid-job. Common across older Tudor and Georgian tile-hung cottages.
