Why Choose Global Energy Insulation

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

Why Improve Your Property EPC Rating

An improved EPC rating is about more than just numbers on a certificate; it is about creating a comfortable, affordable living environment. For homeowners, better insulation leads to significant reductions in monthly heating costs. For landlords in Merthyr Tydfil, achieving compliance with the latest Minimum Energy Efficiency Standards (MEES) is essential for renting out properties legally. By investing in our professional retrofit solutions, you can protect your assets against rising fuel costs while simultaneously increasing the market value and desirability of your property.

Our Whole-House Approach to Energy Efficiency

We follow the rigorous PAS 2035 framework to ensure a whole-house approach to energy efficiency. This process involves a professional assessment to identify specific areas where your property is losing heat, such as through poorly insulated walls or roofs. Our qualified team then implements tailored solutions including External Wall Insulation, Internal Wall Insulation, and high-performance loft upgrades. By addressing thermal bridging and damp issues at the source, we ensure that your property retains heat longer and remains condensation-free throughout the winter months.

Seamless Integration with Global Plastering

We take pride in delivering a clean, high-quality finish on every project. While Global Energy Insulation handles the technical aspects of your retrofit and insulation, our sister company, Global Plastering, ensures the aesthetic side is managed to the highest standard. This allows us to provide a comprehensive, end-to-end service. Whether you require internal plastering to finish off an insulation install or professional external rendering to protect your brickwork, our combined expertise delivers a complete property transformation.

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.
