Old House!

We bought an old property and was looking at how we could run it more efficiently. We contacted Radiant and they sent their guy out who went through everything with us. We had our Air Source Heat Pump and new heating system installed with Radiant. What a great experience from start to finish, talked through everything from the outset and all through the installation. The final handover was very thorough and our system runs and performs amazing! Highly recommend these guys. ⭐️⭐️⭐️⭐️⭐️

Excellent Experience.

I had an excellent experience with this company. From the moment Jason arrived at my home, to the interactions with the office and the installation process, everything was handled with professionalism.
The engineers were clean, organised and took time to explain everything when handing over my Heat Pump. I would highly recommend them. Thank You!

Would highly recommend Radiant Renewables

The whole process of changing our gas boiler to an ASHP could not have been easier. From initial estimate to obtaining the government grant, Radiant Renewables made it simple and affordable. Polite, helpful and friendly staff made it a pleasure. Would recommend to anybody.

Lack of Communication

I’ve had a lot of problems with my heating system which was installed 2020. We became new owners in 2022. Engineers have replaced many parts at great expense since.
In June 2024 I queried the invoice because it included work that had been brought forward from the original quote (as it broke down quicker than hoped). That work was done and paid for in full but appeared on the invoice when the rest of the work was done. I raised this straight away and apology was accepted and a new invoice was to be sent. This never transpired. Due to my experience I raised a number of questions and suggested resolution for consideration. I was informed it had been passed to the managing Director. I chased up by phone and email, he was on holiday, away etc.etc. but nothing transpired. I decided to make a 50% payment of £650 in the interim. Still no updated invoice and no response. Mon 2nd September I received a demand for overdue account for the full unadjusted amount. I emailed accounts with the previous communication no response, I emailed Accounts, a member of staff & the Managing Director, no response, I followed up email today requesting only an acknowledgment of receipt. No response.
So what other mediums can I use as phone calls and emails are not resolving or getting to where they need to be. This is probably a good choice I think to engage the much needed conversation and resolution for all parties

Hello Janice,

Thank you for taking the time to share your feedback. We sincerely apologise for the ongoing frustration you've experienced, and please be assured that we take your concerns very seriously.

Like yourself we inherited the system in 2022, when we took over Radiant, and unfortunately discovered a lack of documentation and records for the project. This has caused difficulties understanding what works have been completed and what’s been invoiced, subsequently delaying communications as we’ve been trying to resolve this matter for you.

Our apologies for this oversight, but the request sent on 02/09 was done so in error and you have now received an updated statement and a credit note. One of our team members has reached out, so please allow us the opportunity to rectify this situation by providing them with the requested information.

Once again, we appreciate your patience and thank you for giving us the chance to make things right. We value your business and are committed to resolving this situation to your satisfaction- Dylan

Installed and maintains our Air Source Heating.

Radiant fitted and maintains our air source heat pump. They have always been very professional and have come when I have had difficulties or concerns. They have excellent technical knowledge and advice. I would really recommend them.

Waste of time

After contacting them by phone, they asked for photos and several details. And then nothing, no reply, no follow up, nothing.

We only used Radient for the design and supply.

We only used Radient for the design and supply of the system. Currently it is running on a remote biomass boiler as part of a district heating system. When the RHI on the pellet boiler expires,we intend to replace it with individual air source pumps, which may get more efficient as time goes on, or if feasible, a bore hole and large ground source pump to replace the biomass boiler. The system works faultlessly . Thanks.

Quick ,efficient and excellent to deal with

We were recommended to this firm by someone living in the village. This company did everything they said they would. Nice to deal with and a good bunch of fitters. I didnt hear one swear word which in these days is unusual with a group of lads.
Office staff professional and pleasant to deal with.

Great technical knowledge and support…

Great technical knowledge and support but equally, very pragmatic in their approach to finding an efficient blended solution across a number of decarbonisation options for our business that were practical and affordable for our specific needs.
