Cold radiators in Matching Green? 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 Matching Green repair callouts we diagnose and fix on the first visit — common parts (PRVs, diverters, pumps, PCBs) live on the van.

About Matching Green
One of the largest village greens in Essex, ringed with period cottages and listed buildings. Heating work here often touches conservation considerations and chimney capping for back-boiler removals.
Period cottages, several Grade II listed. Chimney work needs careful conservation handling.
- Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
- Older Old Harlow properties frequently have low mains water pressure that affects combi choice
- Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces

Common questions about boiler repairs in Matching Green
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.
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.
How fast can you come out?▾
We aim for same-day on no-heat and no-hot-water situations. Tell us when you call if anyone elderly or with young children is in the property — we prioritise.
