Why Landlords and Homeowners Need Better EPC Ratings

With tightening Minimum Energy Efficiency Standards (MEES) affecting rental properties, achieving a higher EPC rating is no longer optional for many landlords. Beyond regulatory compliance, improving your home energy efficiency is the most effective way to eliminate cold walls, reduce condensation, and stop black mould from developing. Our team assesses your property to identify the most impactful upgrades, ensuring your home meets modern living standards while increasing its overall market value. By addressing thermal bridging and upgrading insulation, we help you lower your carbon footprint and monthly utility costs.

Our Comprehensive PAS 2035 Retrofit Process

We take the complexity out of home upgrades by providing a fully integrated service. As a PAS 2030 accredited firm, we manage the entire project from initial Retrofit Assessment through to final coordination. Our process begins with a detailed analysis of your building fabric, followed by the installation of high-quality solutions such as external or internal wall insulation and loft upgrades. Because we are experts in solid wall insulation, we know how to handle the specific needs of non-traditional builds, including many of the local properties found throughout Blaenau Gwent.

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.
