What Happens When You Call
1
You tell us what it's doing
Not resetting for you over the phone. We ask what the display shows, whether it's heat, hot water or both, and how long it's been happening, so we arrive with the right parts already in hand.
2
Full diagnostic on arrival
We check the actual fault before assuming anything, reading fault codes properly rather than clearing them and hoping. Most of our repeat customers come from someone else's guesswork that didn't hold.
3
Clear price before anything's touched
Once we know what's wrong, you get a fixed price. Work only starts once you've said yes.
4
Fixed, tested, and guaranteed
Most repairs finish there and then. We test the boiler properly under load before we leave, not just a quick fire-up, and the work's guaranteed for 12 months.

Why Glasgow's Boilers Fail Differently, Street to Street
Glasgow's tenement flats, still a huge share of the city's housing, often have boilers fitted into original cupboard spaces built for a hot water tank, not a modern combi. Cramped access and limited ventilation aren't just an inconvenience for us, they can genuinely be part of the fault, a boiler working harder than it should because it's not getting the airflow it was designed around.
Post-war semis and estates across areas like Knightswood, Drumchapel and further out towards Cumbernauld and East Kilbride tend to have boilers that are now on their second or even third generation since the house was built, plus original pipework that's decades older than the appliance bolted onto it. Faults here often trace back to the system around the boiler rather than the boiler itself, sludge, old valves, a pump working harder than it should.
Newer flats and conversions, common across the city centre and regeneration areas like Finnieston and Tradeston, mostly run modern combis fitted in the last decade. These fail less often, but when they do it's usually an electronic fault, a PCB or sensor issue, rather than the mechanical wear you'd expect on an older system. Diagnosis here is more about reading the electronics properly than physically stripping the unit down.
Landlord-owned flats across the city add a different pattern again, boilers sometimes installed to the minimum spec that met building control rather than sized properly for the property, which shows up as short-cycling or slow heat-up on the coldest days, exactly when you're most likely to notice and call us. We'll flag honestly when a boiler's simply undersized rather than treating every callout as a straightforward parts failure.
High-rise and multi-storey blocks, common across parts of the East End and the Southside, add a wrinkle most other Glasgow housing doesn't have, communal heating or hot water systems in some blocks mean a fault isn't always inside your own four walls. Part of an early visit on these jobs is working out whether the problem genuinely sits with your boiler or belongs to the building's shared plant, since that changes who's actually responsible for sorting it and who's paying.
Who You'll Get
Mo and David handle most of the boiler repair work across Glasgow, David as a dedicated heating engineer and Gas Safe registered in his own right. Between them they've worked on boilers from every era Glasgow's housing has thrown up, tenement flats with combis wedged into cupboards half the size the manufacturer intended, 1970s semis still running original pipework, new-build flats with boilers barely five years old that have already had three owners' worth of settings fiddled with. The habit that actually saves you money is diagnosing properly before reaching for parts, a habit Mo's held to since his apprentice years and one that means fewer return visits, not more of them. It also means an honest answer when a repair genuinely isn't the right call, David's specifically the one who'll walk you through replacement options if that's where the numbers actually point, rather than fitting a part just because it's the job in front of him.
What Else Often Comes Up
A boiler repair rarely stands alone. Low pressure that keeps recurring is often the first sign of a slow leak somewhere in the system, not the boiler itself, so we'll check for that while we're already in. Cold radiators, especially cold at the bottom, usually point to sludge building up in the system rather than a boiler fault, and it's worth mentioning if you've noticed it, since it changes what we look for. And if a repair turns up a fault on the gas train, the flue or the pressure relief valve, that gets treated as a full Gas Safe check on the wider system, not just a patch on the one symptom you called about. A boiler that's needed two or more repairs inside twelve months is also worth mentioning on the call, that pattern usually means we're looking at the system holistically rather than treating each visit as unrelated, and it's exactly the kind of history that feeds into an honest repair-or-replace conversation.
Pricing, In Plain Terms
We give you a clear price before any work starts. That price is what goes on the invoice. What actually changes the cost on a boiler repair is which part has failed and whether it's one we carry on the van as standard. A common PCB or pump fault on a Worcester Bosch or Vaillant is usually sorted same visit at a predictable price. Something on an older or less common boiler, where a part needs ordering in, costs more mainly because of the wait, not because the job itself is harder. We'll always tell you before starting if a fault looks likely to need an ordered part, so there's no surprise halfway through. That applies just as much to a diagnostic-only visit, where you just want an honest answer on what's wrong before deciding what to do next, you'll always know the price before we start, whatever kind of visit it is.
Repair or Replace?
The honest maths on an ageing boiler comes down to two numbers, how old it is and how many times you've already called someone out. Under ten years old with a single fault, repair is almost always the right call, most parts are still readily available and a modern boiler has plenty of working life left. Past fifteen years, especially with two or more repairs in recent memory, the maths flips, a repair bill on a boiler that's already unreliable is often better spent as a deposit against a new one with a fresh warranty. Between ten and fifteen it depends on the specific fault and the brand, some boilers genuinely run well past fifteen years with basic care, others are troublesome from year eight. Efficiency is worth factoring in too, a boiler from the early 2000s is typically running ten to fifteen percent less efficiently than a current A-rated condensing model, so on an older unit the gas bill saving from replacing it can genuinely offset part of the cost over a few winters, not just the avoided repair bills. We'll give you a straight answer on your specific boiler rather than a generic age cutoff, because that's honestly what the decision comes down to.

“Our radiator pipe was bent and leaking. They answered straight away… Guy was here an hour later and he was wearing ID, very professional, patient and kind. We just got a new carpet in this room and he done an amazing job on getting little to no water on it. Couldn't recommend enough, price was reasonable.”

“We lost heating just in time for the coldest day of the year with a baby in the house… When I contacted them they were ready to dispatch that night. Fixed by the afternoon. Quoted that morning and no extra charges were added. Honestly cannot thank them enough.”
