Why Choose Global Energy Insulation

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

Why Your EPC Rating Matters for Your Property

An Energy Performance Certificate (EPC) does more than just display a grade; it serves as a roadmap for your home's thermal efficiency. For landlords in Llantrisant, meeting Minimum Energy Efficiency Standards (MEES) is a legal necessity for renting out properties. For homeowners, a higher rating often leads to significantly lower monthly heating costs and can even boost the long-term market value of your house. By tackling issues like thermal bridging and inefficient insulation, you safeguard your asset against rising energy prices and future-proof your living space.

How We Deliver Professional Retrofit Solutions

As PAS 2035 retrofit specialists, we follow a rigorous, whole-house approach to energy efficiency. Our process begins with an assessment to identify where your home is losing heat, followed by the installation of high-quality solutions. This may include external wall insulation to wrap your building in a thermal blanket, loft insulation to stop heat rising through the roof, or targeted cavity wall treatments. Our work is fully PAS 2030 compliant and supported by SWIGA-backed guarantees, ensuring that every upgrade is installed to the highest industry standard.

Seamless Integration with Global Plastering

We understand that insulation work often requires a perfect finish. That is why Global Energy Insulation works in tandem with our sister company, Global Plastering. While we handle the technical side of thermal efficiency, rendering, and structural retrofitting, our partners provide high-quality traditional plastering services. This creates a convenient, end-to-end service for you, where structural integrity and internal aesthetics are handled by one trusted team of local professionals.

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.
