How Our Insulation Services Improve Your Home

Heat rises, and in many properties, a significant portion of your warmth escapes directly through the roof. By installing high-quality loft and roof insulation, we create a thermal barrier that traps heat within your living space during the winter while keeping your home cooler throughout the summer. This process is essential for reducing thermal bridging, which can lead to cold spots and long-term damp issues. We pride ourselves on delivering a seamless installation process that respects your home and provides immediate, noticeable results in your energy usage.

Why Choose Our Professional Retrofit Services

We do not just install insulation; we provide a comprehensive retrofit service that ensures your property remains compliant with UK building regulations and the latest MEES requirements for rental properties. Our team is fully CHAS accredited and holds a valid waste carriers licence, ensuring all work is carried out to the highest safety and environmental standards. Furthermore, we offer a complete end-to-end service by working closely with our sister company, Global Plastering. This allows us to handle all internal finishing and plastering requirements, saving you the hassle of coordinating multiple contractors.

Quality Assurance and Insurance Backed Guarantees

We believe in complete peace of mind for our customers in South Wales. Every insulation project we complete is SWIGA-backed, meaning you receive comprehensive, insurance-backed guarantees for the work performed. Being PAS 2035 accredited also means we approach every job with a whole-house mindset, ensuring that insulation upgrades do not inadvertently create condensation or ventilation issues. Our status as a registered company, number 05875199, reflects our long-standing commitment to professional, transparent service in the region.

Roof & Loft Insulation FAQs

Frequently Asked Questions

Answers to common questions about eliminating thermal bridging, reducing heat loss, improving your EPC rating, and our PAS 2030 accredited roof insulation services in South Wales and South West England and across South Wales.

How much money can I save with new loft insulation?

+

Most homeowners in South Wales see a significant drop in their heating bills, often between £200 and £400 a year depending on the size of the house. Because the material lasts for decades, the upgrade usually pays for itself very quickly.

Will I lose my loft storage space if I add more insulation?

+

Not necessarily. While we need to reach a certain depth to meet building regulations, we can use loft legs or raised flooring systems. This allows the insulation to breathe while still giving you a solid platform for storage.

Does roof insulation help with damp and mould?

+

Yes, it does. By keeping the ceiling warmer, you reduce the chance of water vapour condensing on the surface. This is one of the best ways to stop black mould from growing in the corners of your bedrooms.

How long does the installation take?

+

For most standard homes in the Rhondda or Cardiff area, we can complete a loft insulation upgrade in just a few hours. It is a very non-disruptive way to improve your home’s energy efficiency.
