Border Heating Services Ltd provide specialist Gas Central Heating Repair for homeowners across Harlow, Sawbridgeworth and Bishops Stortford. With 18 years' experience, Gas Safe registration and Vaillant accreditation, our engineers carry out methodical fault-finding and targeted repairs — pump replacement, motorised/zone valve work, sludge clearance and thermostat or cylinder repairs. We work by appointment only to deliver thorough diagnostics, compliant parts and full system testing.
Decades of domestic gas heating work mean fast, accurate diagnosis and repairs tailored to UK radiators, boilers and cylinder systems.
Contact the office to describe the fault; we confirm the earliest scheduled slot and the engineer's ETA for a focused visit.
Engineers perform systematic fault-finding with pressure checks, pump tests and valve inspection, then present a clear, written repair plan.
We complete repairs using compliant parts, run full system tests, purge and balance where needed, then leave a safety check and explanation of work.
We repair a wide range of faults including failed pumps, stuck diverter valves, faulty motorised/zone valves, thermostat and programmer failures, sludge-blocked radiators, persistent pressure loss and airlocks. If a part is failing we’ll offer a like-for-like replacement or an upgraded component where appropriate.
