What to know about heat pump repairs in Purley

Aftercare matters as much as installation. For a heat pump in Purley the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.

Across Purley and Greater London, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Purley whoever installed them, including older monobloc and split systems.

When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.

  • Heat pumps installed by another company that need a second opinion
  • Heat pumps showing an error code or fault light
  • Systems losing pressure or needing frequent topping up

What's included

  • Refrigerant repairs by an F-gas certified engineer where needed
  • Supply and fitting of replacement parts
  • Testing of sensors, pumps, valves, pressures and electrics
  • Reading of error history and operating data
  • A clear explanation of the fault and a price for the repair before work goes ahead

Heat pump owners in Purley can arrange a fault-finding visit at a rate agreed before an engineer attends.

Heat pump repairs in Purley: questions

How often should a heat pump in Purley be serviced?

Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.

Will the engineer need access indoors as well as outside?

Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.

How much does a visit cost in Purley?

The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.

Can you repair a heat pump installed by another company?

Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.

How much does a heat pump repair cost?

Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
