Why Synergy
Why customers choose us
88% fixed on the first visit
We find the actual fault first, then fix it, rather than swapping parts and hoping. The van carries the common spares for Worcester Bosch, Vaillant, Baxi, Ideal and Glow-worm, so once the fault is diagnosed we can usually repair it there and then. We measured it: across 505 boiler repairs since October 2023, 88% were finished on the first visit. How we counted.
More than boilers
Heat interface units, air source heat pumps, LPG systems and unvented cylinders. Most local firms cover one or two of these. We cover all of them, with the qualifications to match.
Straight about money
Every price is published before you call. Parts are quoted and agreed before we fit them, and anything we fit carries a 12-month parts warranty. If a boiler is not worth repairing we say so.
What we do
Heating and plumbing, done properly
Every price is fixed and the same whether you are in Handsworth or Halesowen.

Gas safety inspection · Chelmsley Wood · November 2025
Chelmsley Wood landlord inspection: CO reading found, Glow-worm made safe, flue collector replaced
Rust at the back of the heat exchanger and a carbon monoxide reading on the analyser, in a house with a young family. We capped the boiler off, told the tenant and landlord, and replaced the cracked flue collector and gaskets with the landlord's permission.

Radiators · Rowley Regis · March 2026
Rowley Regis: bathroom towel radiator replaced, white curved rail out, chrome ladder rail in
The old white rail had seen better days. We drained it off, hung a new chrome ladder rail on the same pipework, refilled the system with fresh inhibitor and bled it. One visit, no mess.

Boiler repair · Stourbridge · March 2026
Stourbridge landlord follow-up: CDi leak traced to the condensate collector, combustion box stripped and rebuilt
A previous engineer had reported a leak on the safety check. We found it at the condensate collector, whose seals had perished. Everything came out of the combustion box to replace it, and the boiler went back together burning cleanly.

We hold same-day slots for no heating and no hot water, and run a 24/7 line for genuine emergencies. Call early in the day for the best chance of a same-day visit.
Which areas do you cover?
Birmingham and a 10-mile radius of B20 2JS as standard, which takes in Sandwell, Walsall, Dudley, Solihull and Sutton Coldfield. For boiler installations we travel up to 50 miles, including Wolverhampton.
