Common Boiler Problems We Fix
Swanley homeowners call us for a wide range of boiler faults.
Heating Not Reaching Temperature
If your radiators aren't warming up to the level you've set, this can indicate a circulation issue, a failing pump or a problem with the controls. Our engineers will identify the cause and advise on the most appropriate fix.
Hot Water Running Cold
Intermittent or no hot water is a common fault. This often points to a diverter valve issue or a failed sensor. We carry common parts and aim to resolve the issue in a single visit.
Boiler Pressure Dropping
If your system pressure regularly falls, there may be a small leak somewhere in the pipework or a fault with the expansion vessel. We'll investigate, re-pressurise and advise on any parts that need replacing.
Water Leaking from the Boiler
Water dripping from the appliance should always be investigated promptly. We'll locate the source — whether it's a valve, seal or heat exchanger — and carry out a safe, lasting repair.
Boiler Locking Out or Resetting
If your boiler keeps switching itself off, it may be responding to a fault it has detected. Our engineers are trained across all major brands and will diagnose the underlying cause.
Strange Noises
Banging, humming or whistling from your heating system often indicates scale build-up, trapped air or a failing pump. We'll diagnose the cause and recommend the most effective solution.
Fault Codes on the Display
Modern boilers show error codes when something is wrong. Our engineers can interpret these across all major makes and get to the root of the problem without guesswork.
Radiators Cold Despite Boiler Running
If your boiler appears to be firing but your radiators remain cold, this can point to a circulation fault, a stuck valve or air in the system. We'll carry out a full investigation to identify and resolve the issue.

Example Boiler Repair in Swanley
October 2026
A homeowner in Hextable reached out to Heat Cover Ltd after their Vaillant boiler began locking out repeatedly throughout the night. This recurring issue left the household without consistent warmth, causing significant frustration during the recent cold snap in Kent.
Our Gas Safe engineer attended the property and discovered that a degraded expansion vessel membrane was preventing the system from maintaining proper pressure. Following a swift component replacement and full system repressurisation, the boiler was returned to normal operation with both heating and hot water fully restored.
Why Regular Boiler Servicing Matters
Many unexpected breakdowns can be avoided through annual servicing.
Routine servicing allows worn components to be identified before they fail, helps your boiler operate efficiently and may also be required to maintain your manufacturer's warranty.
If your boiler hasn't been serviced recently, we'd be happy to arrange this once your repair has been completed.
