Why choose our accredited insulation experts?

We are a PAS 2030 accredited and SWIGA-backed contractor, meaning we meet the highest industry standards for quality and safety. We understand the unique challenges of different property types in Cardiff, from modern steel-framed industrial units to historic Victorian commercial conversions. Our CHAS accreditation and adherence to rigorous UK building regulations ensure that every project we undertake is fully compliant and professionally managed. We provide a complete end-to-end service, and through our sister company, Global Plastering, we also manage all internal finishing works to ensure a seamless project delivery.

How do we improve your property energy rating?

Improving your EPC rating is essential for meeting current Minimum Energy Efficiency Standards (MEES) and reducing your overheads. Our team uses advanced diagnostic techniques to identify areas of thermal bridging and heat loss within your building envelope. Whether your property requires External Wall Insulation (EWI) to improve the exterior facade or Internal Wall Insulation (IWI) to retain the original aesthetics of a period building, we have the expertise to deliver. By installing high-performance insulation, you can significantly lower heating demand and create a more sustainable working environment for your staff and tenants.

Can we help with your commercial retrofit project?

Every commercial insulation project is different, which is why we offer a tailored approach based on the specific needs of your building. Our services cover everything from complex cavity wall insulation and roof thermal upgrades to full-scale retrofit assessments under PAS 2035 standards. We are experienced in working with a variety of structures and are fully insured, holding a valid waste carriers licence to ensure all works are carried out cleanly and responsibly within a 35-mile radius of our base.

Commercial Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited commercial insulation solutions, EPC rating improvements, and MEES compliance services in South Wales and South West England, South Wales, and the South West.

How will insulation improve my office energy efficiency?

+

Most heat in commercial buildings escapes through uninsulated walls and roofs. By installing high-quality thermal barriers, your heating system doesn't have to work as hard to maintain a steady temperature. This leads to lower bills and a smaller carbon footprint for your business.

Do I need planning permission for External Wall Insulation on a commercial unit?

+

In many cases, EWI is considered a permitted development, but it depends on the building's location and whether its appearance changes significantly. If your business is in a conservation area or is a listed building, different rules apply. We can help you navigate these requirements as part of our retrofit coordination service.

How long does an industrial insulation project take?

+

The timeframe depends on the size of the building and the type of insulation being used. A small office might take a week, while a large industrial warehouse could take several. We provide a clear schedule before we start to help you manage your business operations.

Can you help us meet the new EPC rating requirements for landlords?

+

Yes. We specialise in EPC rating improvement. By carrying out a PAS 2035 compliant retrofit, we can help move your property from a failing grade to a compliant one, making sure you can continue to lease your building legally.
