Viridian Avis 

Excellent service and price, very happy with how we were treated as a customer.

The work was done quickly and at a reasonable price.

Very pleased with removal and refit of loft insulation. The guys did a very tidy job of clearing away decades of cobwebs and worn out insulation. The house feels much more snug already.

The company turned up on the day they said done the job and left the site being cleaned up and very tidy. Well done i believe in praising a company when they do well.
Keep up the good work for 2026 and beyond.
10 star review

your workers were brilliant very helpful I was expecting a lot of dust but every thing was so clean I can not thank yoyu enough for the way the work was carried out and would have no problem recommending you thank you

They work really hard especially as it took longer than expected.

I found viridian excellent throughout. The friendly surveyor visited promptly and gave me the quote at the end of the visit rather than waiting days. The price was competitive and reasonable. The insulation installer was friendly and professional and coped with the ridiculously small loft hatches I have in my old house. He meticulously tidied and hoovered afterwards. I would highly recommend Viridian.

Our cavity wall insulation filling on Friday 14 November 2025 was a very smooth process from beginning (initial quotation, site visit, scope of work) to end (installation, issue of Completion Certificate and Guarantee Certificate). The workmen on the day - Ben B and James - arrived punctually, were polite and friendly, ensured minimum disruption, and tidied up afterwards. Now our house already feels warmer and we're looking forward to a reduction in our gas bills. Overall, we are very satisfied with Viridian and would not hesitate to recommend them.

Arranged Cavity Wall insulation on my clients property.
Very smooth process from start to finish.

I would like to say a big thanks to the team at Viridian!! They have been very professional from when I made my enquiry, they came out same day and quoted there and then. Once the loft boarding and insulation was laid they showed me the work and even hoovered up afterwards. Thanks again

Surveyor Mark visited our property to assess insulation options. We ended up not needing any work done, but what was so impressive was that he was entirely focused on giving us the right advice, even though that ended up in no project work. This is clearly a "customer comes first" company, highly recommended.

Honest and knowledgeable. Installation was done very quickly and professionally. Would absolutely recommend

Ben and Barney arrived on time, were cheerfull, explained in a professional manner. Carried out the job and were professional in all aspects. Great service pleasure to see things done in this manner. 5 Stars 🌟

We were able to book in a survey for cavity wall insulation very easily using the online forms. We had a visit from Matt who was polite and professional, answering all our questions. The two installers (Ben B and Barnie) were also polite, efficient and friendly. They colour matched the holes in the brickwork and dealt with the areas that were difficult to access with ease. They cleared up after themselves and even washed the house down. Happy with the service all round.

Ben/Ted and the team did a great job installing our loft insulation. Worked hard and cleaned up after them, thoroughly recommend Viridian.

Viridian were a very good company to deal with from the initial quotation stage right through to having the loft insulation installed. Our roof of the house was particularly shallow and restricted headroom access but this presented no problems to the 2 workmen who came to install the loft insulation. They were very tidy and cleared up all the rubbish afterwards. This company can be recommended.

Since moving home we have looked around for an insulation company and had various advice and prices ranging to many thousands.. I am in the property business and wanted a top up in a small cavity for 1930 home. I can see voids with thermal camera anyway.
These guys were the only ones to talk sense and had a re-blow of same style fibre after they check it out thoroughly. Price brilliant, service the same! Highly recommend from start to finish super professional, tidy and lovely job. Happy customer!!

Having phoned a couple of companies who were not very helpful I fortunately found Viridian. They definitely reflected their outstanding reviews. They were very prompt in sending someone to look at my loft and couldn’t have been more helpful. I was advised what needed to be done to get the best outcome from loft insulation and at a very reasonable price. I didn’t feel under any pressure from sales talk. Will definitely be using Viridian when I’m ready for the insulation to go ahead.

The job was completed professionally as discussed

Viridian quoted a reasonable price to remove foam insulation from the roof and to replace it with conventional insulation.

The guys that carried out the rather dirty work were polite, informative and cleaned up after their work each day.
