Is Your Heat Pump Not Working Properly?
This service is for homeowners whose heat pump isn't working as it should. If you've searched for help because your system has no heating or hot water, keeps returning the same fault codes, or just doesn't feel right even though your installer says everything's fine, this is exactly the kind of problem we diagnose every week.

Here are the most common ways a heat pump not working shows up, and what it usually points to:
No heating or hot water. This can be as simple as a mode accidentally left on "hot water only," a holiday setting still switched on, or a tripped breaker. It can also point to a bigger issue with the compressor, refrigerant charge, or system controls. It's worth ruling out the simple causes before assuming the worst.

Fault codes that keep returning. A fault code clearing itself and coming back is rarely random. It usually means the underlying trigger, whether that's pressure, flow, or a sensor reading, hasn't actually been fixed, just reset. We help you understand what your specific fault code means and what's really causing it.

Heat pump running constantly. If your system never seems to switch off, it's often struggling to meet the heat demand of your home. This can come down to sizing, flow temperature, or heat loss through the building rather than the heat pump itself being faulty.

Electricity bills much higher than expected. A heat pump that's technically "working" can still be running far less efficiently than it should, often because of flow temperature settings, poor system balancing, or hydraulic issues that quietly push running costs up.

House never reaching temperature. This usually traces back to flow temperature, radiator or underfloor sizing, or how the system has been configured, not necessarily the heat pump unit itself.

Pressure dropping repeatedly. Recurring pressure loss almost always means there's a leak somewhere in the system, and it's worth identifying where before it causes bigger problems.

Heat pump cycling on and off (short cycling). Frequent starting and stopping puts unnecessary wear on the system and is usually a sign the system isn't sized or controlled correctly for your home.

Installer says everything is working correctly, but it doesn't feel right. This is one of the most common reasons homeowners contact us. If your gut says something's off, an independent second opinion can confirm whether it's a genuine issue or just a heat pump behaving differently from your old boiler.

Here's what we look at:
Troubleshooting real issues. If your system isn't working as it should, we'll go through it step by step with you. In many cases, with a willing homeowner, we can identify the issue there and then. Where needed, we can also work alongside your installer, plumber, or electrician to make sure the correct fixes are carried out.

Heat loss and system sizing. Is your heat pump actually the right size for your home? If it's too big or too small, it can cause ongoing issues that no amount of setting changes will fix. We identify whether the system matches your home's real heat demand.

Hydraulic layout and flow. How your pipework is set up has a huge impact on performance. We look at flow rates, balancing, buffers, volumisers, and overall system layout to see whether heat can move properly around the house.

Flow temperature and controls. Flow temperature is one of the biggest factors in both comfort and running costs. We review your settings and identify whether they match the heat loss, radiators, and way the system is being used.

How We Help You Fix It
Once you book, we'll send you simple instructions on what we need to get started, usually a few photos and a brief explanation of the problem. We'll review everything and, if needed, ask a few follow-up questions to properly understand what's happening. From there, we'll arrange a time that works for you to go through everything together on a call. In most cases, we can identify what's going wrong there and then, and give you clear steps on how to fix it.

If the issue comes down to an installation or component fault, you can use your own plumber or electrician. We know many are understandably cautious when it comes to heat pumps, so we can guide them step by step on what to check, test, or adjust to get the system working properly. That guidance is all included. There are no extra charges for helping you or your installer get it resolved properly.

Common Questions About Our Reviews
Why has my heat pump suddenly stopped working?
It's usually one of a handful of causes: a tripped breaker, a mode accidentally changed on the controller, a refrigerant issue, or a fault the system has locked itself out over as a safety measure. A quick review of your settings and fault history usually narrows it down fast.
Why does my heat pump keep cycling on and off?
What do heat pump fault codes actually mean?
Is it normal for a heat pump to run constantly?
