Case studies: real jobs, written from the job sheets
Every job on this page happened. The details come from our job records and the engineer who did the work — no stock stories, no invented customers, and photos only where the customer has agreed to them. Many of these jobs also appear on the local page for their area, and the repairs here sit behind one measured number: 88% of our boiler repairs are finished on the first visit.
Boiler installations and replacements
Willenhall — an Ideal Logic replaced with a Worcester
March 2026. The boiler was losing pressure regularly, and the diagnosis was the expensive kind: the main heat exchanger was leaking internally. We priced the repair honestly alongside a replacement, and the customer chose a new Worcester with a 10-year warranty rather than a major repair on the old boiler. More Wolverhampton work on the Wolverhampton page.
Shirley, Solihull — a combi swap in a bathroom airing cupboard
2022. A Ferroli F24 replaced with a Baxi 600, fitted back into the same airing cupboard — a tight space where neat pipework matters more than speed. We are Baxi Works accredited installers.
Solihull — an open-flued Glow-worm converted to a combi
An older property still running an open-flued Glow-worm with a separate hot water cylinder. The old boiler and cylinder came out and a Worcester 4000 combi went in — the classic conversion to combi, priced from £2,699 fitted.
Tettenhall, Wolverhampton — open-vent system to a combi
A semi on an open-vent system with a tank in the loft went across to a combi. Same fixed price as we would quote in Birmingham, and the loft and airing cupboard both came back into use.
Emergency replacement with a Worcester LPG combi
An end-of-life boiler failed outright and needed replacing as an emergency rather than a planned job. A new energy-efficient Worcester LPG combi went in, backed by a 10-year manufacturer guarantee. Full write-up on our specialist site: birminghamboilerrepair.co.uk case studies.
Boiler repairs
Willow Road, Solihull — the boiler that kept losing pressure
The customer was topping their pressure up every few days, which almost always means water is escaping somewhere. We traced it to a faulty manifold inside their Bosch boiler, collected the replacement part the same day, fitted it and re-tested the whole system before leaving — a December job, so getting the heating back the same day mattered.
Edgbaston — the L2 fault that was hiding something worse
An Ideal Logic showing L2 turned out to be more than a lockout: combustion readings showed dangerous carbon monoxide levels. We made the boiler safe immediately, traced the fault to the gas valve and injector, fitted replacements and fully recommissioned it — exactly why a proper flue gas analyser matters on every repair.
More repairs, straight from the diary
Perry Barr — pressure loss with no visible leak. An Ideal Logic kept losing pressure with nothing showing anywhere. The leak was internal, on the main heat exchanger — we ordered the correct replacement, fitted it and left the boiler holding pressure.
Tipton — Ideal Logic F3 fan fault. We sourced the replacement fan the same day, fitted it and had heating and hot water back that evening.
Handsworth — Glow-worm F75. The pressure sensor had failed. The replacement was already on the van, fitted and tested in one visit.
Quinton, B32 — Glow-worm Betacom F28. The circuit board had failed. Correct PCB ordered, fitted and tested — heating and hot water restored.
Bloxwich, Walsall — dropping pressure. The expansion vessel needed recharging and the pressure relief valve had failed. The PRV is a part we stock on the van, so it was one visit.
Walsall Wood — heating but no hot water. A Glow-worm Easicom with the classic diverter valve failure. Correct part ordered, fitted on the return visit, hot water restored.
Solihull — a Vaillant dripping from inside the case. The leak came from a corroded support bracket inside the casing. We stripped the boiler down, fitted a genuine Vaillant replacement bracket, reassembled and confirmed it leak-free before leaving.
Ariston Evo — no hot water, boiler overheating. The plate heat exchanger was blocked. We collected the part mid-visit rather than booking a return, and hot water was back the same day.
Sutton Coldfield — Gledhill Pulsacoil, no hot water. A less common electric system many repair firms will not touch. The immersion heater had corroded; we replaced it and tested the full system before leaving.
A gas leak under the floorboards. A suspected leak with no visible source. We traced it to a damaged section of copper pipe beneath the floor, repaired it and confirmed the system safe.
Three of those repairs are written up in more detail, with fault-and-fix job tickets, on our specialist repair site.
Heating systems and commercial work
Ortado Mediterranean Turkish Grill, Dorridge
Summer 2025. While this brand-new Dorridge restaurant was being fitted out ahead of opening, we installed its designer radiators and completed the plumbing works — commercial heating in a new-build venue, with the finish chosen to match the interior.
Shirley — the twelve-year-old boiler that was sludging up
A Shirley semi with a boiler only twelve years old was already losing pressure every few weeks and sludging up — no filter, no inhibitor. A power flush and a magnetic filter sorted it and protects the boiler for years.
Your job could be next
If any of these sounds like your boiler, the starting point is the same one every job above began with: a phone call and a proper diagnosis. Repairs are £99 including diagnosis and the first hour; installation quotes are fixed before we start.
