Warm, or your money back.
We put it in writing.
We've been designing and installing heat pumps since 1999. Now part of EDF, Britain's biggest generator of zero-carbon electricity, we back every install with a promise few others make.
If it doesn't keep you warm,
we fix it or refund you.
If your heat pump doesn't keep your home at the design temperatures we agreed with you in its first year, we'll fix it. If we can't, we'll refund you.
Year 1
warmth guaranteed to your agreed design temperatures, or your money back

Real homes. Real words.
Every review counted.
“It's the best investment we've ever made. It's cosy and warm all year round. It's surpassed all of our expectations.”
“So nice to have a warm house during the winter at last, after 30 years here of needing to add an extra jumper or two.”
“They completed all the grant application so no stress for me at all! The installation team Chris & Cieran were extremely professional.”
“The quote was prompt, simple to understand and clear… including the BUS grant (no effort from me).”
“We had a very smooth experience getting our heat pump… The Ideal heat pump works well and is nearly silent most of the time.”
“Enquire what you want without any hard selling.”
“Our oil boiler became old and inefficient… it provides a consistent warmth rather than instant heat.”

Clean heat needs clean power.
That's what EDF makes.
A heat pump only delivers its full carbon saving when the electricity behind it is clean too. EDF is Britain's biggest generator of zero-carbon electricity, and we're a wholly owned part of it.
- Power from five nuclear power stations, more than 35 onshore and 3 offshore wind farms, and solar
- Building Hinkley Point C, which will power around 6 million homes, with Sizewell C planned
- Sister companies Pod Point for EV charging and Contact Solar for solar panels and batteries
- The Heat Pump Tracker tariff, backed by zero-carbon electricity EDF generates itself
