Business Information

Insulating your home has been a long standing way of keeping your fuel bills down.

Great quality insulation will improve the way your home keeps the heat in, while keeping the cold out.

Upgrading your boiler is another great way to keep fuel bills down. In a typical semi-detached property that uses mains gas for heating you can reduce your heating bills by around £300 per year by upgrading your boiler.

Absolutely fantastic service from start to finish. The whole team was professional, friendly, and really helpful throughout the process of getting my new boiler installed. Everything was explained clearly, the work was completed to a very high standard, and they made the whole experience stress-free. The installation was tidy, efficient, and completed on time. I’m extremely happy with the new boiler and would highly recommend this company to anyone looking for reliable and quality service.

I had Retrofit in to install a new boiler. From the first phone call to Billie in the office, through to the boiler installation being signed off the communication and workmanship was exemplary. Id highly recommend this company and already have put a couple of friends in touch with them to get similar work carried out.

I arranged for a boiler replacement & loft insulation to be done on behalf of my elderly auntie as she was unsure of who trust in the trade.
The service was 10/10 from start to finish. Every member of staff involved on the project, from office to tradesmen were professional, informative & genuinely cared about their job. They put an old lady at ease with their professional attitude.
Have recommended this company to other people who have also been delighted with the service & results
5 star company ⭐️⭐️⭐️⭐️⭐️

Had a Vaillant air source heat pump and solar panels installed last year and everything went so smoothly. My biggest concern was replacing oil boiler with ASHP but its honestly made such a difference. Guys explained everything beforehand and took me through how to operate and keep tabs on my bills afterwards via the solar app. So glad I went ahead and would recommend Retrofit Group to anyone.

The company was great from start to finish, from the all staff on the phones to the guys who done the work…new boiler, loft insulation, fan and heater in the kitchen nothing was too much bother for them.
