No Heating or Hot Water in Cardiff? Emergency Help
Every no-heat call in Cardiff gets the same first minute: is there any smell of gas? If yes, that changes everything — off the property, call 0800 111 999. If no, we move to the boiler checks and get a Gas Safe engineer moving.
Safe checks while help is on the way
Work the outside-the-case list: thermostat turned above room temperature and programmer calling for heat; credit on a prepayment meter; other gas appliances working (a dead hob suggests a supply issue, not a boiler fault); pressure gauge at 1–1.5 bar, topped up via the filling loop if low; and in freezing weather, the condensate pipe — a frozen section thawed with warm water, then reset pressed, revives more winter boilers than any other single action. If the boiler still won't run, stop: everything further requires a Gas Safe engineer.
Why boilers fail in cold snaps
Cold weather is a stress test. Marginal pumps, tired expansion vessels and hesitant igniters all pass it in September and fail it in December. Add the condensate-freeze lockouts that arrive with the first hard frost — particularly on pipes run externally without lagging, common across Roath and Cathays — and the seasonal spike explains itself. A pre-winter service catches most of it early; the emergency line catches the rest.
Emergency pricing, straight
Emergency attendance in Cardiff runs from £99 covering call-out and the first hour, quoted on the phone before dispatch. Parts are priced before fitting. If your situation can safely wait for a next-day standard slot at a lower rate — heating down but hot water working in mild weather, say — we'll tell you that instead of dispatching an emergency you don't need.
Pricing for no heating or hot water in Cardiff tracks the national bands closely, with the usual local caveats: access difficulty in older Roath properties, parts availability for the boiler families common here, and the seasonal demand curve that makes autumn bookings cheaper and calmer than January ones. You will always see the price structure before an engineer travels.

Frequently asked questions
I can smell gas — what do I do?
Don't use the form and don't wait for us: open windows, don't operate electrical switches, get everyone out, and call the National Gas Emergency line free on 0800 111 999 immediately. Once the property is made safe, we can arrange the follow-up repair.
Is a frozen condensate pipe really that common?
In the first hard frost, it's the single most common cause of boiler lockout in the UK. The white plastic pipe running outside freezes, the boiler senses the blockage and shuts down. Warm — not boiling — water over the frozen section, then reset, restores most of them. Lagging the pipe stops the repeat.
Will you charge me a call-out just to press reset?
We try hard to prevent exactly that: the phone triage walks you through pressure, condensate, thermostat and reset checks first, free. If an engineer attends and finds a genuine fault, normal rates apply; the checks exist so you don't pay for a visit a jug of warm water would have solved.
What information should I have ready when I call?
The boiler make and model if visible, any error code on the display, whether you have gas at other appliances, the pressure-gauge reading, and your postcode. Thirty seconds of facts routes the right engineer with the right parts far better than five minutes of description.
