Old boiler was well past its best, spoke to Craig, our local heating engineer whovrecommendedva Geant boiler as a replacement. Left it to him to supply and fit one, heating is greatly improved.

New property with Grant underfloor heating and water system. Experiencing problems with hot water and having to reset the fan multiple times. Engaged plumbers and electrician who installed the system and after both inspected they advised that it was a potential fault. With no other option than to call Grant out as an in warranty issue (over 1 month to attend), the engineer found no fault and advised that there would be no charge. 5 days later received a bill for £150 for the 20min visit. Unacceptable

I recently had a Boiler installed by Swale / Sureserve.
The Boiler is short cycling every 3 minutes, for the last 6 weeks I have been trying to get the installers Sureserve to fix the problem without success, appointments noone turning up, 3 call outs and still
have the problem.

They told me to contact Grant UK, the heating engineer there said its a installation / commissioning problem.
Also said their call out is £150 and £70 every half hour if they find its not a boiler at fault! Boiler is under Warranty.

Back to Swale,Sureserve again.
Paid for a installation job / commissioning of boiler that came to just over 7k. Really not sure why they cant resolve this, wont give up! it goes on!

The true test of the quality of a company is what happens when something goes wrong. Giorgia in the customer service department was fabulous. From the outset and throughout she was responsive, highly informative, brilliantly organised, and above all she showed that she (and Grant Engineering) cared for their customers. An easy 5 stars to give 🌟

Replacement for an older, but similar, version of the oil fired boiler. It appears to do the job better and more efficiently than the old and fits in the same space.

Splendid professional customer -caring confident service Well done and many thanks 👍

I have a problem with heat pump communication issues and everyday I need to top up the pressure for the tank not yet solved yet, contacted installer and the Grant UK but still the same issues. ..waiting the Grant engineer...sorryat the moment for star reviews. ..

Great company, great support, will be moving my buisness here going forward.

Waiting 4 months for a service. Too few engineers - fire fighting.

After years of an unreliable Boiler I just can’t believe my luck. No worries about anything any more.

IMS were extremely professional throughout both the supply and fitting side of the project. We would highly recommend them both for initial advice and for the fitting of the pump.

Excellent service. Bang on time. Friendly staff.!!! Breath of fresh air.

I recieved excellent and prompt service, and the engineer solved my boiler malfunction immediately. Very good communication from the office staff to arrange my call out and after sales care was perfect. Thank you.

Excellent product

We have a Grant Air Source Heat Pump system that was installed about 11 months ago. A few days ago we suddenly had no heating so we contacted Grant, fully expecting them to tell us that there would be a delay as we are after all in the middle of one of the coldest spells for ages. However, Grant managed to get one of their engineers (Neil) out to us this morning and everything is sorted! The engineer has found the fault and the underfloor heating is back up and working. Thank you Neil (the engineer) for a quick, fast and professional service.

I contacted Grant due to an issue with my parents boiler. Paul the Technical Support manager dealt with my request in a polite and quick timescale. Paul's knowledge allowed him to quickly identity the issue and arrange the repair to be performed asap.

Dealing with Paul at grant has been a breath of fresh air as years of dealing with various other support staff in other companies i was expecting the usual slow, unhelpful staff but Paul was brilliant.

Have had our boiler less than 2 years and breaks down on average 3 times a year and their customer service is shockingly bad, I am still awaiting it to be looked at by them from breakdown in November and that's it broken down again. It will have a complete set of new parts at this rate with the amount the engineer is having to swap out. DO NOT BUY GRANTS

Boiler installed and running with no issues at this early stage

I have rung Grant twice in the past and had brilliant service from their tech department but this morning was a different story the guy was very abrupt everything was a “no” he just couldn’t be bothered.

Trouble free installation, compact unit, excellent heat supply and easy to operate.
