New Kitchen installation

We chose Andy from Retrofit Group to fit our Howden’s budget kitchen. Andy has such a good eye for detail and assured us in advance that any issues that arose, he would sort them. He fixed all teething issues and snags and nothing we asked was too much of a problem. After we chose our kitchen, Andy dealt directly with Howdens so that we didn’t need to which meant no stress for us. The team were very pleasant and respectful to have in the house and good to work with. Communication was excellent and they took on board all our comments as the work progressed. They even used the back door to access the house and put boards on the grass to prevent it getting ruined. Very thoughtful team. Our finished kitchen is really gorgeous and bright and we are delighted! Thank you all!

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.

Unprofessional and pushy

I’m extremely disappointed with my experience.
They came to my property to carry out an EPC survey to assess eligibility for insulation. The survey itself went well - the gentleman who visited was friendly and polite, and shortly afterwards I was informed that we were eligible.

However, due to having young children and a very busy schedule, I wasn’t able to respond immediately. In what felt like a very short space of time, I was then told that materials had already been ordered and that I had been booked in for the work - without me signing anything or giving any formal agreement to proceed. I was completely shocked. Why would a company order materials and schedule a job without clear confirmation from the homeowner?

After doing further research and reading other reviews, I decided the insulation wouldn’t be suitable for us. I became concerned about how much smaller it would make the room and the issue of a doorframe being too close to the wall. I explained this once I had the chance.

Instead of understanding, I was told that they had already spent hours on this and that the least I could do was take a call the next day. I clearly explained that it wasn’t a good week for me and that I wouldn’t be available for a phone call. That should have been respected.

Unfortunately, they continued to press the issue. This week happens to be the anniversary of my son’s death - something deeply personal that I did not initially feel I should have to explain. When I reiterated that I would not be taking a call and that I had never agreed to the work, the response I received was extremely rude. I was told it was unfair of me to “put that on him” and that my message was disgraceful.

At no point did I sign or agree to any contract. I feel the company acted prematurely and then handled the situation very unprofessionally when I chose not to proceed.

Based on my experience, I believe I have dodged a bullet. I would strongly advise others to be cautious and ensure nothing is progressed without explicit written agreement.

Thank you for taking the time to share your feedback. Firstly, we would like to say how sorry we are to read about the personal circumstances you mentioned and sincerely apologise if any communication you received at that time caused additional distress.

We are pleased to hear that your experience with the assessor who carried out the survey for your EPC was positive. He is a member of our team and we are proud of the professionalism and courtesy our assessors aim to demonstrate when visiting customers’ homes.

However, we would like to clarify that the other individual you have referred to is not an employee of our company. This person is a member of a separate third-party lead generation company, which works with a number of installers across the industry. They handle some of the early-stage contact with customers following an eligibility check.

We want to be clear that our company does not authorise installation work, order materials, or proceed with any project without a homeowner’s explicit agreement. If any communication from a third party suggested otherwise, that is not reflective of our processes.

We also do not condone anyone speaking to a customer in a manner that could be perceived as rude, dismissive or pressuring. Your feedback has therefore been shared with the third-party company involved so that this can be addressed appropriately.

We appreciate you bringing this to our attention and are sorry that the overall experience left you feeling uncomfortable. Should you wish to discuss this further, please feel free to contact us directly and we will happily review the matter in more detail.

Many thanks,
Retrofit Group

Not regarding to anyone.

Not regarding to anyone.Just be aware people of this company. They come over to do insulation in my property and they destroy our paving and leave our garden in total mess. Run like rats away from my property and don't even let us know that they finished the job because they know what they done. Contacted the company and they refused to fix it and of course they said they not done anything.People be aware

Hi Artur,
I have requested some further information from you via Trustpilot as we don’t recognise your name nor have we had any complaints of this nature so fear you may have stumbled on our domain by accident. We are a Glasgow based company. If you can reply via Trustpilot so we can investigate this it would be much appreciated.
Thanks and hopefully speak soon

Amazing company, amazing service.

Cannot thank these guys enough for my new boiler! I am super chuffed. From the first phone enquiry to the day of installation, I couldn't believe how quick and easy the whole process was! What a fantastic, friendly and very professional service! I highly recommend these guys.

Cost Saving

A big thank you to Retrofit Group who fitted our loft insulation, a new boiler, extractor fans in both bathroom and kitchen, and also trickle vents in all windows inside and outside plus a heating element beneath a cupboard in the kitchen, which was provided through the Eco 4 system, all the workmen were very thorough and tidied up after they were finished. The heating engineer started at 8am and as it was a big job didn't finish till 7.45pm ensuring everything was working even the office staff were 1st class in their communications .

Great company, Gets the work done.

The company and the work team were amazing.
I was dreading having my boiler replaced, however this was made really easy by the organised manner in which the work was carried out. I would have no worries in sending anyone to them to have work carried out. Thank you so much, so pleased with the result. Shirley
