Why Choose Global Energy Insulation

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

Why Your Home Energy Performance Matters

Many older properties in Rhisga and Risca suffer from significant heat loss due to inadequate insulation. When your energy rating is low, you are effectively paying to heat the outdoors, which leads to exorbitant winter bills and potential issues like condensation or black mould. By upgrading your insulation, you can boost your EPC rating from a D or E to a C or higher. This not only makes your living space more comfortable and healthy but also adds tangible market value to your home while reducing your carbon footprint.

Comprehensive Retrofit Services and Compliance

We take the complexity out of energy upgrades by managing the entire process under PAS 2035 standards. As a PAS 2030 compliant contractor, our team conducts thorough assessments to determine the most effective solutions for your specific building type, whether it is a solid wall construction or a Wimpey no-fines build. We offer a full range of upgrades including External Wall Insulation, Internal Wall Insulation, and loft and roof treatments. Every project we undertake is SWIGA-backed, providing you with an Insurance Backed Guarantee for total peace of mind.

How Our End-to-End Installation Process Works

Our service begins with a professional retrofit assessment to identify exactly where your home is losing heat. Once we have established the most suitable upgrades, our skilled installers get to work using industry-leading materials that meet all current UK building regulations. Because we operate alongside our sister company, Global Plastering, we provide a seamless finish that avoids the need for multiple contractors. From start to finish, we ensure that your property is left in pristine condition while meeting the highest technical standards.

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.
