What to know about heat pump repairs in Romford
Aftercare matters as much as installation. For a heat pump in Romford 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.
We repair heat pumps in Romford whoever installed them, including older monobloc and split systems. Across Romford and Greater London, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- Refrigerant repairs by an F-gas certified engineer where needed
Outdoor units in exposed spots around Romford can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Romford quote.

Heat pump repairs in Romford: questions
How often should a heat pump in Romford 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.
Can you work on a heat pump in Romford that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Romford, whoever fitted them. Tell us the make and model when you get in touch.
How much does a visit cost in Romford?
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.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
