GRS Insulation Ltd Avis 

No messing from start to finish. Graeme responded quickly to my enquiry. He identified my problem and gave a great quote. Within a couple of days Tyler and Jason installed the insulation i needed. They were hard working efficient and explained exactly what they were doing. Despite the weather having been reasonable since, we can immediately tell a difference. Very happy to leave this feedback and would recommend this company.

Business like approach during the survey and pricing. When the installation day came, the installer was friendly and efficient.
Very pleased with the result and now looking forward to a toastie warm house next winter.

Everything went very well. The crew arrived on time to the minute. They worked non stop until the job was completed. I was very happy with the result, and would recommend them to anyone.

We had an insulated flat roof installed at our property under a government grant scheme by GRS Insulation. Unfortunately our experience has been very disappointing.

After the work was completed we experienced multiple problems including water coming through a bathroom light fitting, which actually filled with water and caused damage to the ceiling. We also had water entering the boiler cupboard affecting the electrics, which resulted in a power cut and the boiler shutting down leaving the house without heating.

Although engineers attended and carried out some repairs to the roof and restored the electrics and boiler, further problems have continued. Water is now running down the front of the house due to the threshold drainage being too close to the property and is coming in through the front door. There are also still outstanding remedial works inside the property including repainting the damaged bathroom ceiling and replacing the light fitting.

The property is tenanted and there is a vulnerable child living in the home, so these issues have been extremely concerning.

We are currently waiting for the company to provide a proper plan and timescale to fully resolve the problems caused by the installation.

Great experiance from start to finish,professional service from start to finish.

Highly recommend.

Prompt service, good quality work, tidied up nicely afterwards

Straight forward processes, staff always willing to help and.advise.

did a great job on time and explained what was being done cleared up afterwards and provided photos of the work
friendly staff both on phone and on site

Very friendly staff, an excellent quote and very quick to install. The fitter was very friendly and clean, with no mess left. I cant fault them.

Work carried out diligently and helpfully.

From the initial contact about a survey, to the survey itself (and several, subsequent and very reassuring chats with Graeme) to the day of the install (can’t remember the two installers’ names but they were both friendly and skilful), GRS were fantastic.

Our EPC said cavity wall insulation (assumed). Turns out it had none! Bonded bead installed today with a 25 year guarantee and we couldn’t be happier. Has made an instant difference to how our home holds onto heat.

Highly recommended!!

They were very professional, and offered a speedy service with minimum disruption and mess.

The team ho came to the house where polite and professional

The professionalism of the installers

Good workers helpful for giving me information good job good

Communication within the company should be improved among employees. The left hand frequently did not know what the right hand was doing. Information gathering systems were not optimal. We received numerous emails and telephone calls about the same paperwork. There was a lot of unnecessary duplication. Most of all, we were given the wrong information which led to disappointment when the promised improvement could not be carried out.

In January 2025 we were seriously let down by an insulation company based in Wolverhampton. After nearly nine months of constant heartache we finally managed to get our money back. We looked around for a local company and were recommended to use GRS Insulation Limited and we have never looked back. They inspected the loft area and advised us on the work to be carried out. They also advised us to approach the local council for a possible grant which was approved. Since day one the company have always been upfront and most importantly honest. The guys who came out and did the actual insulation, installation of the two air vents and loft entrance and boarded area were excellent. Finally to the team in the administration office who were always at the end of the phone if we had any questions and even paid us a visit on a counter of occasions. Thank you one and all for being such a star team.

Friendly and helpful staff, arrived on time and seemed to work efficiently but left a lot of brick dust all over wall lights. House feels warmer already!

After a year of disappointment with the cavity insulation industry, I finally found a company that were interested in the customers needs, not thier own.
Installers were friendly, knowledgable & very helpful to have a good job completed.
Would certainly recommend against other companies I looked at & used.
