Why Choose Global Energy Insulation

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

Why Improve Your Property EPC Rating?

Upgrading your Energy Performance Certificate is about more than just a score; it is about taking control of your monthly outgoings. Many homes in Y Coed Duon and Blackwood struggle with thermal bridging, leading to heat loss through walls and roofs. By implementing targeted insulation upgrades, you can significantly reduce your reliance on expensive heating systems, effectively slashing your energy bills. For landlords, achieving a C rating or higher is essential for MEES compliance, ensuring your rental property remains legal and attractive to prospective tenants in the competitive South Wales market.

Our Approach to Whole House Retrofit

As a PAS 2030 compliant contractor, we handle the entire process from initial assessment to final sign-off. Our team identifies the specific measures your property requires, which may include External Wall Insulation, Internal Wall Insulation, or loft and roof upgrades. We are experienced in working with diverse property types, from classic period homes to non-traditional builds like Wimpey no-fines housing. By working in tandem with our sister company, Global Plastering, we ensure that every internal finish is completed to a high standard, providing a seamless, end-to-end service for every project.

Local Expertise and Regulatory Compliance

Navigating UK building regulations can be complex, but our team manages every detail for you. We are fully accredited, PAS 2035 ready, and hold a valid waste carriers licence, ensuring your project is compliant and professionally managed. Every installation we undertake is backed by the Solid Wall Insulation Guarantee Agency, giving you complete peace of mind that your investment is protected. We are proud to serve the residents of Y Coed Duon, Blackwood, and the surrounding Caerphilly area, helping local properties meet modern efficiency 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.
