Cold radiators in Cheshunt? Boiler repairs sorted properly
One radiator cold? Bottom cold and top hot, or top cold and bottom hot? Each tells you something different about what's wrong. We diagnose by touch and by pressure, not by guesswork — and we fix it without changing your boiler if we don't need to. Most Cheshunt repair callouts we diagnose and fix on the first visit — common parts (PRVs, diverters, pumps, PCBs) live on the van.

The same engineer quotes the job, does the work, and answers the phone afterwards if anything's not right.

Common questions about boiler repairs in Cheshunt
Top cold, bottom hot — what's that?▾
Air in the radiator. Usually a 30-second bleed sorts it. If the same radiator keeps re-airing, you may have a slow leak or a corrosion gas problem.
Bottom cold, top hot — what's that?▾
Sludge build-up at the bottom of the radiator. Often fixable with a powerflush or a dose of system cleaner. Whole-system sludge usually means a powerflush is the right call.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
