Why Choose Global Energy Insulation for Cavity Wall Insulation in Ferndale & Rhondda Cynon Taf?

How Cavity Wall Insulation Improves Your EPC Rating

One of the most effective ways to improve your home's EPC rating is by addressing the empty space between your external walls. By filling these cavities with high-quality insulation, we create a thermal barrier that traps warmth inside during the winter and keeps your home cool in the summer. For landlords in Tredegar, this is a crucial step toward meeting MEES compliance regulations. Our team understands how to boost the thermal performance of your property, ensuring it meets current energy standards while protecting the structure from damp and condensation.

Professional PAS 2030 Standards and Local Expertise

Quality assurance is at the heart of everything we do. As a PAS 2030 accredited company, we strictly adhere to PAS 2035 retrofit standards to ensure your home is treated with the care and technical precision it requires. We are fully insured, hold a valid waste carriers licence, and are proud to be SWIGA-backed, offering our clients long-term peace of mind through insurance-backed guarantees. By choosing our local team, you are opting for a reliable service that values building regulations and professional integrity above all else.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited cavity wall insulation, reducing heat loss, and lowering winter energy bills in South Wales and South West England, Rhondda Cynon Taf, and across South Wales.

How do I know if my home in Ferndale has cavity walls?

+

Generally, houses built after the 1920s have a cavity—a gap between two layers of brick. You can usually tell by the brick pattern; if all the bricks look the same length, it’s likely a cavity wall. If some bricks look shorter (the ends of the bricks), it is probably a solid wall. We can confirm this for you with a quick survey.

Will cavity wall insulation cause damp?

+

When installed correctly by a PAS 2030 accredited professional, it actually helps prevent damp by reducing condensation on cold walls. We always check for existing issues and ensure your home has the right ventilation before we start.

How much money can I save on my bills?

+

According to the Energy Saving Trust, the average semi-detached house can save significantly on heating costs every single year. Given the current energy prices in the UK, the insulation often pays for itself in just a few years.
