Most heat pump problems aren't caused by the heat pump. They're caused by how it was set up.
Independent heat pump servicing, fault finding and optimisation across Hampshire, Surrey and Sussex.
I find the real cause — and help put it right properly.
Most heat pump owners were handed a system they don’t fully understand, high bills, confusing controls, rooms that wont heat properly. These problems are almost always fixable, and they’re rarely caused by the heat pump unit itself.
Ashby Energy specialises in aftercare for existing heat pump systems. I’ll tell you what’s actually happening, whats causing it, and what it will take to put it right.
Already have a heat pump — but something isn't right?
“A very big thank you to James who went above and beyond sorting my heat pump system out, he diagnosed the fault and ordered the required parts. He attended the following week and soon had the system working again. He then spent an extra hour confirming everything was working as it should be.”
— Alan, BasingstokeWhy independent matters
Many heat pump companies are focused on selling and installing new systems. Ongoing aftercare is harder to access.
My main focus is existing systems — servicing, diagnostics, controls and optimisation.
I'm not tied to any manufacturer or installer, which means my advice is based on what's right for your system, not what's easiest to sell.

He attended the following week and soon had the system working again. He then spent an extra hour confirming everything was working as it should be.”
— Alan, Basingstoke“James carried out servicing and optimisation works on our heat pump and heating system and we couldn’t be happier with the service provided.
