EDF Heat Pumps Reviews 677

one star as the hot water temperature and pressure is great and CB heating finished sort off finished in time frame.
However if you want a warm house do not bother. We are now spending £35.00 a day powering the pump yet it is unable to get the house higher than 20.6 deg.
Have even tried running on boost all day, no difference.
Even after turning it off via the app and setting holiday
on the Hive for 6 days(Which showed was set to 7 degrees) still managed to use £70 electricity.
EDF give a heat guarantee however to date, this is a waste of time as our system is fully 'optimised' yet still not good.
We had an efficient oil boiler before, really wish we hadn't changed, was always turning that system down.
This is substantially disappointing especially as the EDF Solar panels and battery storage was so good in July.
Stay clear

We have had the heatpump installed for a year or so now and sincerely, I think it is a better system than having a boiler but unfortunately ours has not been working efficiently as it should, particularly in the winter..our house is installed with triple glazed windows and that should have helped. CB heating, now EDF Heatpump have replaced the units to try and get it right and tried to fine tune the system few times but it is still not working efficiently as it should because , I am not sure if the design was the problem. Since the start of October winter month, we have been hovering around 17⁰ to 18⁰ room temperature which is bad. Initially it was the hot water that was the problem because we have a big family and the hot water tank runs out quickly and we had to adjust using less hot water or wait for a while for the tank to refill. So overall, the system can be better if they can get it right. I really still don't know what to do if we have to go back to gas central heating and install a boiler.

Very satisfied with installation,Dan and Connor from DJS heating did an excellent job fitting my heat pump and boiler,very tidy efficient and courteous,top marks to Dan Connor and EDF

The system seems to be meeting target after talking with edf.so the back up was v good.we will however just keep monitoring

I am absolutely delighted with my new heating system from EDF Heat Pumps and would highly recommend their services. From start to finish, the design and installation process was handled fantastically well by all concerned - Ramya; Craig; Charles and Nathan (EDF Heat Pumps, Clacton-on-Sea); Cieran and Chris (CJL Plumbing & Heating, Llanelli); and Ethan (EJS Electrical, Llanelli). All were the very model of helpful; courteous; professional and hard-working and made the whole process from start to finish a complete pleasure. Thank you.

The heat pump was installed professionally although there could have been more time spent on explaining how it all works as you were left with the manual and very little explanation

Excellent installation once we got the brilliant installation team appropriate to our property. The system works very well indeed.
But, unfortunately, we are not well off enough to afford it being on as we would like.

Love my new heat pump & getting more use of it with the weather being colder. I have an old stone cottage, built into the side of a hill & was led to believe that it would be difficult for a heat pump to cope. Not true - it’s doing a great job. Downside- it’s quite big & takes up quite a bit of space in my small garden. I’m hoping the environmental advantages make up for it.

I cannot warn people strongly enough about CB Heating (EDF Heat Pumps). This has been the worst customer experience I have ever had with any contractor.

From the outset, the installation was riddled with serious faults — including live electric cables left exposed, which resulted in my builder being electrocuted. This was not just careless; it was dangerous. No one from CB Heating took accountability for this health and safety breach.

Despite repeated visits by different engineers, the system still does not function properly. The hot water pressure is inadequate, the heating fails to reach the upper floors, and we suspect the system was running on emergency immersion settings for two months, causing extreme energy bills — all this despite having solar panels and battery storage. Multiple engineers have acknowledged issues, but I have yet to receive a single formal report.

The outdoor unit was delivered damaged, with dented grilles, and although CB Heating promised to repair this, nothing was done. Improper pipework, incorrect pressure pump installation, and unprofessional behaviour from senior management only added to the nightmare. One them mistakenly sent an internal email to me talking very ill of my person.

To top it off, after raising all of these concerns, I was met with threatening legal letters demanding full payment — despite the fact that the installation is incomplete and defective. They even claiming for unpaid gas and electric bill when I’m with Octupus. I was even falsely accused of cancelling the finance agreement, which I did not do. CB Heating’s managing director has sent aggressive emails with unfounded legal threats, completely ignoring the long list of unresolved faults. They claiming for the full amount for the installation including the BUS funding £7500, which I’ve received confirmation from Ofgem that EDF have successfully claimed/received.

This entire ordeal has taken a major toll on my family’s wellbeing. The stress has been so severe that I had to withdraw from a postgraduate scholarship worth £20,000. I have spent over £100,000 on my home with other reputable contractors with no issues — CB Heating stands alone in its lack of professionalism, accountability, and technical competence.

I sent two formal complaints to EDF which was ignored. I have now referred the matter to HIES, Ofgem, and NAPIT, and I will not hesitate to pursue legal action. If you value your home, your safety, and your sanity, stay away from CB Heating.

Since my review I can see EDF has claimed that I have fabricated the claim. If anyone wishes to connect with me please find my on Google review: I will send copies of emails, pictures, videos, emails from Ofgem confirming EDF received the BUS payment of £7500. My heating still doesn't work on the top floor and the pressure pump never worked. They are so proud of their partnership and their influence that they have forgotten their values.

I've been left with a system that makes very loud bangs every time it reaches desired temperature. Have to turn off at night to stop the banging. I've been calling every other day for a month with no call backs till today to say can't fix till new year.
I sent an email a couple of weeks ago saying I would report to MCS to which the MD replied telling me not to threaten them and that things would be fixed.
Cold weather due next week and a system I cant use at night, great Christmas.
On top of this neighbours have complained to council about the noise.
Only had the system a couple of months and I've lost any faith that this and any future problems will be fixed in anything like a timely manner.
20/1/26 It has now been fixed. A lot of the delay was down to a 3rd party contractor so I will improve my rating. Pity they don't keep things in house so would have more control on outcomes.

Great guys fitting my system always left place clean & tidy

Good communication, brilliant installers , tidy and nothing was to much trouble.

Poor at best, the quality of the installation was terrible and they refused to address the issue, my advice don’t do it..

Really excellent experience right from the initial discussions to the final installation. The customer support we received throughout from Lana B was exceptional - quick to respond and provided regular updates. Could not have wished for a better experience. Made a change in heating technology very easy going

We had a very positive experience with EDF Heat Pumps. They were very helpful and were always on hand along the way. Our EDF representative was Ramya and she was very helpful, professional and polite, an asset to your company.

Very good experience. Very informative, professional and competent service. Would highly recommend there services.
Safe to say happy customers.

Writing in praise of EDF and their sub contractor Amalfii Heating, our air source heat pump installation and radiator replacement went very well and was completed to a very good standard. Communication from EDF was excellent at every stage of the process. Special thanks go to Samantha Barlow and Stephanie Byrne.

EDF were very quick to process our heart pump as we had no central heating. It was only a few weeks between first enquiring and installation. The work was done professionally and the installers were courteous and knowledgeable. Great service and highly recommended. The heat pump is working beautifully and we have a lovely cosy house again.

The whole installation process was carried out very professionally, the care taken was exceptional and the work was very tidy and neat. The performance of our system has not disappointed, it is lovely to come home to a warm environment.
