    SMOOTH AND STRAIGHTFORWARD CAVITY WALL INSULATION BY VIRIDIAN

    Posted 21 November

    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.

    Very professional

    Posted 16 October

    From the initial survey, through to the works being carried out, the team at Viridian were great. Communication was good, and all the contractors were courteous and worked hard. When an issue arose (no fault of the installers), they were quick to help find a solution. They worked quickly but thoroughly and left absolutely no mess. Very professional from start to finish, I would have no hesitation in recommending Viridian.

Viridian is a home insulation specialist based in Ashford, Kent that focuses solely on insulation products and services. Our supervisors and senior installers are employed by us, which means we don't use external subcontractors, and are skilled to a high standard and approved by our system designers.

Our loft insulation products are soft, non-itch, non-combustible, with low levels of dust release, and are made of 80% recycled material, which means they do not contain any volatile chemicals. For cavity wall insulation, we use material that has excellent thermal performance. It is also water-repellent, rot-proof, non-combustible and non-toxic in the event of a fire, which makes it durable and reliable in all weather conditions.

Viridian has access to UK government grant schemes providing free or part-funded insulation for private homes, housing associations and local authorities.

Memberships and approvals

PAS 2030

Why use a PAS 2030:19 approved company? The PAS 2030:19 standard became mandated for all funded energy efficiency measures effective on 1st July 2021.

PAS (publicly available specification) is a British Standards Institute (BSI) standard which sets out the requirements for installing commissioning and handover of Energy Efficiency Measures (EEM’s) in domestic retrofit projects. Its main objective is to assist installers in complying with its requirements for EEMs, providing installation specification for a measure specific Annex. Compliance with the PAS standard requires each installation to meet all of the requirements of PAS 2030.

All retrofit installers who want to install one or more specified EEMs under public funded schemes such as ECO need to be PAS 2030 certified to access these schemes. PAS is required for all funded works such as ECO, Local Authority Delivery Funding and the future Home Upgrades Grant. It is a fundamental requirement under the TrustMark Scheme Rules.
