I needed help concerning an existing Icynene roof installation. Although not an existing customer I was amazed at the length they went to find and give me the information that I needed. On this alone I would highly recommend them as a reputable company.

Very good
They're quick to respond to requests. Installation was quick and quiet. I've already noticed the difference the foam makes.
They're helpful and can help with unexpected problems - I discovered some condensation on my roof prior to the installation and they offered to get a heater delivered to me to dry the loft out as the foam needs to be sprayed on a dry surface.

Pitch roof Insulation- Green Homes
I would highly recommend Thermoprotect as a home insulation provider.
Having recently used them to install pitch roof insulation, I was thoroughly satisfied with the end to end service. At the outset they provided a very competitive quote, which was not over priced, and around 40% less than another Green Homes Grant accredited supplier, on a like for like basis.
On approval of my Green Homes voucher, the Thermoprotect team were immediately able to schedule me in for a pre-installation survey and shortly afterwards, the pitch roof foam was installed. Lead time from voucher confirmation to installation was less than 2 weeks.
Both the office staff, as well as the on site team, were very punctual, polite and professional.
We have immediately noticed a much warmer house, and look forward to a saving on our energy bill.
In summary, please use Thermoprotect if you require home insulation. Our experience has been very positive throughout the entire process.

I had foam loft installation installed in my house by Thermoprotect. I can't express how pleased I am with this company. Their office staff were helpful pointing me in the direction of getting a government grant which I wouldn't have done if left to my own devices. Their installers again were pleasant and did a clean tidy job. I know it's early days but I have felt the benefits of this insulation already. A great company and a good product!

Life savers!!
Adam and Richard at ThermoFoam have supported us with our Guarantee for the loft insulation. Unfortunately due to COVID our mortgage was put at risk or collapse. Richard and Adam have supported with this extreme time sensitive issue. Im sure at some stage they got fed up from hearing from me lol. Great communication and understanding from Adam and Richard.
Thank you.
