Why Choose Global Energy Insulation

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

How our PAS 2035 retrofit process works

We take the complexity out of energy efficiency by following the rigorous PAS 2035 framework. Our process begins with a detailed retrofit assessment of your property to identify exactly where heat loss is occurring. We then develop a tailored plan that may include a combination of External Wall Insulation, Internal Wall Insulation, and loft upgrades. By integrating these services, we ensure that your property meets current UK building regulations while addressing specific issues like thermal bridging and condensation. Our sister company, Global Plastering, complements our insulation work by providing high-quality traditional plastering for a flawless finish.

Why prioritise your home energy efficiency today?

Improving your EPC rating is not just about environmental responsibility; it is a practical solution to rising energy costs. Better insulation significantly reduces heat loss, preventing drafts and dampness, which creates a healthier living space. For landlords, reaching required EPC ratings is essential for MEES compliance and ensuring your rental properties remain legal and attractive to tenants. Our team provides robust solutions for diverse property types, including solid wall homes and non-traditional structures such as Wimpey no-fines houses, significantly enhancing both thermal efficiency and long-term property value.

Our credentials and commitment to quality

Trust is at the heart of everything we do. Global Energy Insulation is fully PAS 2030 compliant, CHAS accredited, and holds a valid Waste Carriers Licence. We work under the umbrella of SWIGA, meaning our work on solid wall insulation comes with the reassurance of an Insurance Backed Guarantee. We are fully insured with comprehensive public liability coverage, providing peace of mind to our clients throughout South Wales and the South West, including areas like Cardiff, Swansea, Newport, Bridgend, and Bristol. As a locally based firm, we pride ourselves on delivering reliable, professional service for every project.

Common questions about EPC upgrades

Many homeowners ask if improving an EPC rating is disruptive. While installation takes time, our team works efficiently to minimise the impact on your daily life. A common question is whether a single measure is enough; usually, moving from a D to a C rating requires a combination of wall and loft insulation to be truly effective. We handle everything from the initial assessment through to final coordination, ensuring your home meets the necessary standards without the stress of managing multiple contractors.

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.
