Why Choose Global Energy Insulation

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

How PAS 2035 Retrofit Standards Benefit Your Property

As PAS 2035 accredited specialists, we do not just apply insulation; we take a whole-house approach to energy efficiency. This standard ensures that every upgrade we recommend, from loft insulation to advanced wall treatments, is perfectly suited to your building's specific construction type. By assessing how your home breathes, we prevent issues like condensation and damp while maximising thermal performance. Our process ensures that your home meets current building regulations and safety standards, providing you with a reliable path to a better EPC band.

Why Choose Professional Insulation for Your Home?

Many properties in the Vale of Glamorgan suffer from significant thermal bridging and poor heat retention. By opting for high-quality external or internal wall insulation, you can stop the cold from seeping through your walls, creating a much more comfortable living environment. Our sister company, Global Plastering, works closely with us to ensure that any internal insulation work is finished to the highest standard, leaving your home looking pristine. This combined expertise means we offer a seamless, end-to-end service for all your insulation and finishing needs.

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.
