We diagnose first, then talk cost — charged by the hour, one-hour minimum, nothing padded on top. You decide before work goes ahead.
One fee, not two
No call-out charge, no separate diagnostic fee. The £85 covers investigation, diagnosis where possible, and the first hour of labour.
Tested before we leave
If a part needs ordering we'll say so; where we can finish on the day, the system is tested working before we leave.

Why Croydon homes break down
Croydon's housing runs the full span from Victorian terrace to town-centre tower — each era fails in its own way.
Victorian terraces, combi in a cupboard
The inner-north terraces were subdivided into flats decades ago, with combi boilers squeezed into kitchen cupboards. Three things take them down: ventilation that gets sealed over as cupboards are boarded in, condensate pipes that freeze on the first hard frost, and limescale from Croydon's hard water clogging the heat exchanger. The frozen-condensate no-heat call is our most common job in January.
Suburban semis & detached
Original small-bore pipework and decades of incremental patching. The faults we're called to here are pressure loss, sludge blocking the radiators, and a seized pump or diverter valve — wear that stays quiet until a cold snap forces the issue. Most are a same-visit fix once we've found the cause.
Back-boiler replacement combis
A distinct Croydon pattern: combis fitted to replace back-boiler units twenty to twenty-five years ago, now at the end of their design life. This is the borough's most common repair-or-replace conversation — and we diagnose it honestly, telling you when a repair has stopped being worth the money rather than chasing one more fix.
Town-centre flats, modern condensing combis
Modern sealed systems throw a fault code rather than simply stopping. What we see most is a frozen external condensate pipe, a low-reading pressure sensor, or a PCB or fan fault — the code narrows it down fast, and the common parts ride on the van for a first-visit fix.

Repairs we've done for customers in Croydon
"Boiler had been banging away for weeks then died completely. Someone out the next day, turned out to be the pump. He didn't have one with him but ordered it and was back the following morning to fit it. Heating's been spot on since. Can't fault them."
"Honest review. The engineer was about 40 minutes late for the powerflush, but he rang ahead to say there'd been a bad smash on the A23 and I could see it backed right up on Waze, so no complaints from me. Once he was here the work was spotless and the radiators are hot top to bottom for the first time in years. Worth every penny."
"We manage around forty properties across Croydon and Bromley and have used Flame On for CP12 renewals across the portfolio for the past eighteen months. Turnaround is reliable, the engineers communicate clearly with tenants, and documentation is always accurate. They understand what a letting agent actually needs."
Boiler repair questions in Croydon
How quickly can you reach Croydon for an emergency callout?
Our base is in Central Croydon, so we can typically reach most of the borough within 15–20 minutes off-peak — often quicker in the inner districts (CR0, CR7). Same-day attendance is realistic for most urgent callouts, and we'll give you an honest attendance window when you call, not an optimistic one.
My boiler is in a kitchen cupboard and keeps cutting out — what's wrong?
In the CR0/CR7 terrace conversions that's usually one of three things: a condensate pipe that's frozen after a cold night, inadequate ventilation where the cupboard has been sealed over time, or limescale on the heat exchanger from Croydon's hard water. We diagnose which it is on the visit and fix it there where we can — frozen condensate is often cleared within the hour.
