Wokingham's Local Plumber & Gas Engineer
The Plumbing & Heating Experts
Your Neighbours Trust.
We're based just outside Wokingham in Arborfield, and we've been sorting out broken boilers, leaking pipes and tired heating systems since 2015 — though Stuart's actually been doing this over 20 years. We turn up when we say we will, tell you the price before we start, and more often than not, get it fixed in one visit.

Stuart doesn't guess. He diagnoses the actual fault, gives you a price, then fixes it — usually there and then. He carries parts for Vaillant, Viessmann, Worcester Bosch and Glow-worm on the van, so most jobs don't need a second visit.
From £96 fixed price
Labour only — excluding parts and materials
Get it repaired →Annual Boiler Servicing
Miss a service and you risk voiding the warranty — and with Wokingham's hard water, heat exchangers scale up faster than most places. An hour with Stuart now beats a dead boiler in January.
£96 fixed price
Includes full safety check & Benchmark certificate
Book a service →Landlord Gas Safety Certificate (CP12)
It's a legal requirement and the fine for missing it isn't small. Fixed price, digital certificate emailed same day. Stuart liaises with your tenant directly if needed — just give him the number.

Book your CP12 →Home Buyers & Sellers Heating Checks
Moving in Wokingham? A pre-purchase boiler check has saved buyers thousands when it flags a failing heat exchanger before they sign. Sellers get a clean report that reassures buyers and speeds up sales.
From £150
Buyer inspection: £192 · Seller service & CP12: £150
Book an inspection →Powerflush & System Cleanse
Cold at the bottom of your radiators? Banging when the heating fires up? That's magnetite sludge, and it's slowly wrecking your pump. A powerflush clears it out for good, and it usually knocks a bit off your heating bill too.
From £550
Price depends on system size & number of radiators

Hive, Nest, tado° — fitted by the only Hive-trained engineer in Wokingham. Customers typically see a 16% drop in heating bills. Takes about an hour and you'll never come home to a cold house again.
From £300
Hive, Nest & tado° — supplied & fitted
See options →Water Softeners & Treatment
Wokingham water is 330–380 mg/L hardness — some of the worst in England. It furs up boilers, clogs showers and wrecks appliances. A water softener pays for itself in years, not decades.

Gas Safe 599015 · Verified“Twenty years in boiler rooms around Wokingham teaches you to spot a bodge job a mile off. I just don't do them.”
I set up Thermotec because I got sick of how this trade treats people — turning up in some vague four-hour window, quoting one price and billing another, then having to come back out three months later for the same job. Wherever I'm working, whether that's Wokingham, Woodley, Earley or out round RG40, I do it the same way: find out what's actually wrong, tell you what it'll cost before I touch anything, and fix it properly so I don't have to come back.

Why Thermotec
Why Wokingham homeowners choose Thermotec for boiler repairs & plumbing
An actual arrival time
Stuart tells you when he's coming, and that's when he turns up — not a four-hour slot that wrecks your whole morning waiting in.
The quote you get is the bill you pay.
What Stuart quotes is what you pay. No call-out fee tacked on afterwards, no surprise extras once he's already in your kitchen.
Most jobs sorted in one visit
The van's properly stocked and the diagnosis is thorough, so nine times out of ten there's no waiting around for a part to arrive.
You speak to Stuart. Not a call centre.
Whoever answers the phone is the person who turns up and does the work. No subcontractors, no call centre passing you around.
Based right on your doorstep — 10 minutes from Wokingham town centre
Stuart works out of Arborfield and covers the whole RG40 and RG41 patch. If your boiler's gone and you're in one of the areas listed, he can usually get to you the same day.
Book a same-day visit →Areas I Cover
Wokingham & RG40: Stuart covers the whole town — Norreys, Emmbrook, Cantley Park, right through to Woosehill and Barkham Road. A lot of the 1960s and 70s houses around here still have old system boilers, and more often than not, swapping to a modern combi alongside a powerflush is the better long-term move.
Earley, Woodley & Winnersh: Newer builds round this way mostly already have combis fitted — a lot of Vaillant ecoTEC and Worcester Greenstar. Stuart is a Vaillant Advance Partner, so when he services or installs one he does it exactly the way the manufacturer requires, which keeps your warranty intact.
Arborfield & Shinfield: This is where Stuart is based, so it's a real mix — older places with a tank in the loft, newer estates with unvented cylinders. Stuart is G3 qualified, which is the legal requirement to work on those pressurised systems, so he can sort either type without passing you on to someone else.
