Why Choose Global Energy Insulation

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

Why Your EPC Rating Matters for Treherbert Properties

For landlords and homeowners, an energy performance certificate is more than just a piece of paper. With stringent MEES compliance regulations, rental properties must meet specific energy standards to be legally compliant. Beyond regulation, a higher rating directly translates to reduced heat loss, lower monthly fuel bills, and a significant boost to your property value. We identify the root causes of thermal inefficiency, such as thermal bridging or poor wall insulation, and implement targeted solutions to ensure your home performs at its best.

Our PAS 2035 Approach to Energy Upgrades

As PAS 2035 retrofit specialists, we do not believe in one-size-fits-all fixes. Our process begins with a professional assessment to understand how your specific building type interacts with the local South Wales climate. We offer a full suite of services, including external wall insulation, loft insulation, and advanced rendering systems. By following strict PAS 2030 standards, we ensure that every upgrade is safely installed, durable, and fully compliant with current building regulations.

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.
