Is it right for you?

Is it time for a service?

A good fit if

  • Your air source heat pump hasn't been serviced in the last 12 months
  • Your heat pump is under warranty and the manufacturer asks for a yearly service

Probably not the right fit if

  • Your warranty says only certain engineers can service it. Check the terms before you book, and tell us the make and model
  • Your heat pump isn't a Vaillant or Panasonic air source heat pump. At the moment, those are the two we service

Tell us the make and model when you get in touch.

NuRenewables Heating Ltd have been outstanding from the very start. Every single time I've called them out, they've gone above and beyond what I'd expect — always punctual, polite, and incredibly helpful. The quality of their workmanship is excellent — everything is done thoroughly and to a very high standard.

What really sets them apart is their knowledge and expertise. They've always taken the time to explain things clearly, give honest, sensible advice, and never try to push unnecessary work on me. I really trust their recommendations.

On top of that, the pricing is exceptional value for money — fair, transparent, and worth every penny. And what truly impresses me most is the ongoing support and service after the job is finished. They don't just disappear — they're there whenever I need them, ready to help with any questions or follow-up.

If you're looking for a reliable, knowledgeable, and trustworthy heating company, look no further. I'm so glad I found them — highly recommended! Thank you for such wonderful service every time.

Questions

Heat pump servicing questions, answered

Which heat pumps do you service?

Vaillant and Panasonic air source heat pumps, at the moment. They're the brands we're trained, qualified and experienced with. That isn't knocking any other brands: fewer brands mean more focus, and a better understanding of the units.

How often should a heat pump be serviced?

Most manufacturers recommend once a year, and many make it a condition of the warranty. Check the terms that came with yours.

Will a service keep my heat pump warranty valid?

It depends on the manufacturer's terms. Some say who can carry out the service and what qualifications they need, so check your warranty paperwork before you book, and tell us the make and model when you get in touch.

What can I do between services?

Keep the outdoor unit clear of leaves, plants and anything that blocks the air flow, keep an eye on the system pressure, and let the weather compensation do its job rather than switching the system on and off like a boiler. More in our 10 commandments of heat pump usage.

My heat pump costs more to run than I expected. Can you help?

We offer heating system design and optimisation. See heating design and optimisation.
