What customers say

Based on genuine customer reviews

Households modernising properties under the ECO4 scheme are the focus of much of the work described. Installations range from loft, cavity wall and room-in-roof insulation to air source heat pumps, new radiators, solar panels, extractor fans and improved ventilation, with plastering and electrical work completed alongside. Something that features in review after review is how smoothly the whole process runs, with surveys booked quickly and every stage explained in plain terms.

Named staff such as John, Tommy, Mick, James, Sam, Chris, Alex, Theo, Arran, Graham, Carl, Matt, Michael, Carrie, Lee, Leon and Graeme appear in feedback, with customers calling them polite, friendly and hard working. Tidiness recurs too: furniture and floors were protected, mess cleared each evening and everything put back afterwards, even in homes with young children or elderly relatives. Workmanship is described as efficient and professional, with jobs finished in a few days and little disruption. Several reviewers mention the advice given on controlling new heating systems, plus the willingness to answer questions once the work was complete, leaving them satisfied with the results.

Team worked hard & long but left me with open wires hanging, no ceiling, no heating that I am still without for 5 months. My full freezer unplugged, broken Henry vac, broken mirror, fittings & blinds for both lounge windows gone. I think you get my experience of Green Improve!! Complained many times, was in bed to keep warm, Christmas & months before & after freezing, nothing in compensation or response from them, extremely dissatisfied will be getting legal advice. Taking Chemo to top this!!

Theo did a great job at my property, installing extractor fans in my kitchen and bathroom. He was friendly, informative and considerate. I would highly recommend this company.

We recently moved into our house and we decided to opt into the government scheme for cavity wall insulation and improved ventilation. We would highly recommend Green Improve and the whole team were a delight to work with. The survey was arranged quickly and at a time and date that suited us. The surveyor was polite, thorough and he explained everything that was involved in the installation. Alex did the cavity wall insulation and Theo did the vents and window ventilation. We knew this was a messy job having installed an extractor fan at our previous house but both Alex and Theo were amazing. They cleaned up after the work, they were so friendly and polite it was a pleasure having them at our house. I have a 15 year old dog who is terrified of strangers and Theo was fantastic with her. My husband is an electrician so Theo was under the spot light and he did an amazing job! 100% trustworthy and professional company. I will be contacting my local Labour MP to sing the praises of Green Improve!

Absolutely superb service from start to finish. The work was executed extremely quickly, and was tailor made to the household needs. I could not recommend the service Green Improve (and their affiliates) offer, highly enough. I will also be using their aftercare services to keep on top of servicing etc., going forward.... Excellent. xxxx

The team did fantastic work for our old house. Everything was done with high level of professionally and very quickly. Insulation, gas boiler and radiators installed and we are living in warm comfort now. We wish everyone the same warm Christmas as us now in our renewed house.

Really excellent and speedy survey and installation of cavity wall insulation through the GBIS scheme. I got referred to them by Octopus after the initial installer failed to provide an installation date after 4 months. In contrast, Green Improve completed both their survey and install within 5 weeks of the referral. Only downside is that they don’t allow private funding – they only do work through the government schemes. Otherwise, great people and great quality of work and service.
