Before you book: heat pump repairs in Wood Green
Whoever installed your heat pump, aftercare can be arranged in Wood Green. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
For repeated faults in Wood Green, the engineer looks at the system design as well as the failed part. Across Wood Green 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.
- Heat pumps installed by another company that need a second opinion
- Systems losing pressure or needing frequent topping up
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
We repair heat pumps in Wood Green whoever installed them, including older monobloc and split systems.
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 Wood Green quote.

Designing for Wood Green's winters
On the shortest day Wood Green gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Wood Green.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Wood Green: questions
How much does a visit cost in Wood Green?
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.
How often should a heat pump in Wood Green 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 Wood Green that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wood Green, whoever fitted them. Tell us the make and model when you get in touch.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
