Why Choose Global Energy Insulation

South Wales’ Leading Experts in EPC Rating Improvement & PAS 2035 Retrofits

Why Your Home Needs An EPC Upgrade Now

For landlords, achieving a minimum EPC rating of C is becoming a crucial requirement for MEES compliance, ensuring your rental properties remain viable and legally compliant. For homeowners, a better EPC score is about more than just numbers; it is about reducing heat loss and eliminating the cold drafts that make winter in the South Wales valleys uncomfortable. By addressing thermal bridging and upgrading insulation in your loft, roof, or walls, you can prevent damp and black mould issues while significantly lowering your monthly energy bills.

How Our PAS 2035 Accredited Team Can Help

We take the complexity out of energy efficiency by acting as your dedicated PAS 2035 retrofit specialists. Our process begins with a professional assessment to identify exactly where your property is losing heat. As a PAS 2030 compliant contractor, we manage the entire retrofit journey from initial survey to installation. This includes everything from External Wall Insulation to comprehensive internal thermal upgrades, ensuring every project meets the latest UK building regulations and safety standards.

Seamless Renovation With Our Integrated Services

One of the key benefits of working with Global Energy Insulation is our ability to provide a complete end-to-end service. While we focus on the high-performance insulation and energy-saving technology required to improve your property, our sister company, Global Plastering, manages all the internal finishing work. This means you do not need to coordinate multiple trades; we ensure that once the insulation work is complete, your home is left with a professional, high-quality finish that is ready to decorate.

EPC Improvement FAQs

Frequently Asked Questions

Answers to common questions about boosting your EPC rating, achieving MEES compliance, and our PAS 2035 accredited retrofit insulation services across South Wales and South West England and South Wales.

How much will my EPC rating improve with wall insulation?

+

It depends on the current state of your home, but adding External Wall Insulation to a solid-wall property can often jump your rating by one or even two full bands. This is because walls can account for up to 35% of a home's heat loss.

Do I need planning permission for External Wall Insulation in Ferndale?

+

In many cases, EWI falls under permitted development. However, if you live in a conservation area or a listed building, rules are stricter. We can help you check with the local authority to make sure everything is done by the book.

How long does a PAS 2035 retrofit take?

+

The assessment usually takes a few hours. The actual work, such as installing insulation or new rendering, can take anywhere from one to three weeks depending on the size of your house and the weather.

Is there a way to fix damp and improve my EPC at the same time?

+

Yes. Often, damp is caused by "cold bridges" where moisture condenses on cold walls. By installing professional insulation and breathable silicone rendering, we keep the walls warm and dry, solving the damp problem while boosting your energy score.
