Why Choose Global Energy Insulation

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

Why prioritise your home energy efficiency in Powys

Many properties in the Y Gelli Gandryll area suffer from poor thermal retention, leading to high bills and uncomfortable living spaces. Improving your EPC rating is not just about meeting regulations; it is about tackling fuel poverty and protecting your property from condensation and damp. Our team identifies the specific areas where your building is leaking heat, whether through uninsulated solid walls, draughty loft spaces, or thermal bridging. By addressing these core issues, we help you lower your heating bills while significantly increasing your property value.

Navigating PAS 2035 and MEES compliance

For landlords in Hay-on-Wye, meeting Minimum Energy Efficiency Standards (MEES) is a legal requirement for renting out properties. We take the stress out of compliance by managing the entire process under the PAS 2035 framework. As accredited retrofit specialists, we ensure that every insulation upgrade—from External Wall Insulation to loft improvements—is carried out to the highest industry standards. We handle the technical assessments required to move your property up the EPC bands, keeping your investment compliant and future-proofed.

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.
