Why Choose Global Energy Insulation

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

Why Is Your EPC Rating Important for Your Home?

An Energy Performance Certificate is more than just a document; it is a clear indicator of how well your home retains heat. For landlords, reaching an EPC rating of C or above is increasingly vital for MEES compliance, ensuring rental properties remain legally viable. For homeowners, a higher rating often leads to significantly lower monthly utility costs and an increase in overall property value. By addressing thermal bridging and poor insulation, we help you transition from inefficient ratings to a comfortable, high-performing home that stands up to the Welsh winter.

Our Expert Approach to Whole-House Retrofitting

As a PAS 2035 accredited specialist, we take a holistic view of your home. We do not just apply insulation; we assess how your entire building breathes and functions. Our process begins with a professional retrofit assessment to identify the most effective upgrades, such as External Wall Insulation for solid walls or loft insulation to stop heat escaping through your roof. By integrating these services, we ensure that your property meets current UK building regulations while preventing common issues like damp and black mould.

Seamless End-to-End Service from Our Local Team

What sets us apart in the South Wales region is our ability to manage the entire project from start to finish. Our sister company, Global Plastering, works in tandem with our insulation specialists, providing high-quality internal finishing that ensures your home looks as good as it performs.

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.
