What to know about heat pump repairs in Basildon
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
We repair heat pumps in Basildon whoever installed them, including older monobloc and split systems. Heat pump owners in Basildon can arrange a fault-finding visit at a rate agreed before an engineer attends.
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
- Heat pumps showing an error code or fault light
- Heat pumps installed by another company that need a second opinion
What's included
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
Repairs in Basildon that need a part ordered are explained and priced before the engineer leaves.
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 Basildon quote.

Designing for Basildon's winters
On the shortest day Basildon 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.

- We confirm the fault-finding rate and arrange a visit in Basildon.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Basildon: questions
Can you work on a heat pump in Basildon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Basildon, whoever fitted them. Tell us the make and model when you get in touch.
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 often should a heat pump in Basildon 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.
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.
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.
