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

Why choose our local retrofit experts

We pride ourselves on our deep understanding of the local building stock in Ystradgynlais and the wider South Wales region. As a PAS 2035 accredited company, we look at your home as a whole system rather than just filling gaps. This ensures that every installation is safe, compliant with UK building regulations, and effectively reduces moisture risks. By partnering with our sister company, Global Plastering, we provide a complete, end-to-end service, meaning any internal finishing required after insulation is handled by our own trusted, expert team.

How our insulation process works

Our process begins with a comprehensive technical survey to confirm your property is suitable for cavity wall insulation. We check for existing wall ties, signs of structural moisture, and potential thermal bridging points. Once confirmed, our installers use premium-grade materials to fill the wall cavity, creating a consistent thermal envelope around your home. Every installation is strictly monitored to ensure it meets the highest standards for performance and longevity, leaving your home warmer and more comfortable throughout the year.

Can cavity wall insulation improve your EPC rating

Improving your EPC rating is essential for landlords in Ystradgynlais who must meet current MEES compliance, but it is equally vital for homeowners looking to increase property value. Adding insulation to your walls is one of the most cost-effective ways to boost thermal performance and reduce your energy bills. We provide detailed advice on how these improvements impact your EPC, ensuring your home complies with modern energy standards. We are also well-versed in insulation grants and ECO4 requirements, providing you with the necessary guidance to make your retrofit project as affordable as possible.

Quality assurance and local standards

Trust is at the heart of everything we do. Global Energy Insulation is fully insured and holds a Waste Carriers Licence, ensuring that your property remains clean and professional throughout the installation. All our work is backed by SWIGA insurance-guaranteed protection, giving you peace of mind that your investment is secure for years to come. We don't just insulate; we provide a high-quality, long-term solution to damp, condensation, and heat loss.

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.
