I can not thank Warma UK enough for the excellent install of a new boiler & central heating system at my elderly mums property. Every person was a pleasure to deal with. Tom the engineer was professional, worked late & made sure the unstall was done quickly & efficiently. I have just received a follow up call from them to check that I am happy and that there are no problems nor complaints. Thank you to Liam in Sales, Louise & Danielle in Surveyors & Installation too. Highly recommend

Thank you Warma UK for your help with the boiler installation and accessing the government grant. We didn't have hot water since just before Christmas so the new boiler is wonderful. The fitter was really kind and explained the new controls clearly. I felt a bit concerned about not using a local installer known to me but Warma were great and I would recommend.

The staff were always helpful and friendly. It took about 2 months to get the grant claim to be finalised. I did have a few hoops to jump through getting it all sorted as there was so much red tape. Once sorted it was full steam ahead. Calling the contact centre who were working from home the staff were very knowledgeable and helpful. Rob and Danielle pushed my application through. As my claim was over 2 years the criteria changed and I needed to provided more information and photos. The equipment arrived before installation and the workmen arrived on time. It took 3 days for the complete installation. The workmen were conscientious and kept me informed, we did a walk through to discuss location of boiler and the radiators. This was a difficult job with my flooring being lifted upstairs for the pipe work. The workmen Dave, Steph and Steph worked well with each other came in and just got on with it. They put dust sheets down and ensured they kept my home clean and tidy. Well done the experience was a great one.

How refreshing to deal with such an efficient and friendly company. Completed my grant application last night, expected to wait days but had a call today from James Luff to go through the initial steps of applying for the grant. He was a pleasure, informative, polite, efficient and appeared genuinely invested in my application so it’s a very good start - fingers crossed the rest of the process is as easy. Thank you James, you’re an asset to your employer. Cheers Ali

Stop the Presses........... Warma UK have been brilliant from start to finish..... I initially spoke to Rob who was very knowledgeable and guided us through the process with ease, we were given a grant towards the cost of the boiler as on Attendance Allowance which Warma were very well versed in and made it easy to understand, after a brief time for the grant to pass and payment to process.... I was past over to the installation team and a very friendly and helpful professional named Liam, he made things even easier, kept me updated on the process and even though they were dealing with lockdown, corona virus causing problems and people working from home made it feel like there was nothing different going on. Our installation went ahead as planned and the installer was very helpful adherent to social distancing and wearing masks all the time. Liam on the day was also in contact with me making sure everything was going well and after completion made sure we were happy with the job done! Furthermore has offered a refund for unused pipes which was a kind and generous thing to do. All in all a brilliant process from start to finish! Amazing customer service! Would 100% recommend Warma UK if you are looking for home improvements. Many thanks to Liam, Rob and team.

I’m grateful to Gareth, Danielle and Max for helping me get my new boiler installed. My house was so cold but now back to warm and cosy. I’m highly impressed with how efficient Max is and of course he delivered a service with a smile which always helps despite everything going on in the world. Yes one more happy customer. Merry Christmas 😁
