Why Choose Global Energy Insulation

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

Understanding the Path to MEES Compliance

For landlords in South Wales, meeting Minimum Energy Efficiency Standards (MEES) is no longer optional. An EPC rating of E or higher is a legal requirement for rented properties, and these standards are becoming increasingly stringent. We act as your primary partner in achieving compliance, utilising our deep knowledge of PAS 2035 standards to guide you through the process. Whether your rental portfolio requires enhanced loft insulation, cavity wall treatments, or comprehensive external wall insulation, our team manages the technical requirements to protect your investment and ensure you remain fully compliant with UK regulations.

How Our PAS 2035 Retrofit Process Works

Our process begins with a professional assessment to understand exactly how your property is losing heat. As PAS 2030 compliant contractors, we take a whole-house approach to retrofitting rather than simply applying quick fixes. We look at the building fabric, ventilation, and thermal bridging to create a bespoke plan that delivers measurable results. Our team coordinates every stage, ensuring that the installation of high-performance insulation and advanced rendering systems meets strict quality benchmarks. By choosing our services, you gain access to a reliable, accredited team that understands the complexities of retrofitting older homes in the Rhondda Valley.

End-to-End Solutions with Global Plastering

We pride ourselves on offering a complete service that goes beyond basic insulation. While Global Energy Insulation focuses on the thermal envelope and structural performance, our sister company, Global Plastering, ensures that every internal and external finish meets the highest aesthetic standards. This partnership allows us to offer a seamless transition from the initial insulation phase to the final interior plastering or external rendering. Whether you need a robust silicone render to protect your exterior walls or expert internal finishing after wall insulation, our unified team provides a single point of contact for your entire project.

Quality Assurance and Local Accreditation

Trust is at the core of everything we do. We are a CHAS-accredited business with full public liability insurance and a valid waste carriers licence, ensuring complete peace of mind for every client. Our solid wall insulation installations are backed by the Solid Wall Insulation Guarantee Agency (SWIGA), providing you with long-term, insurance-backed protection. Because we are based locally in South Wales, we understand the specific challenges posed by our regional climate, from high rainfall to exposed hill-side locations. You can rely on us to deliver durable, compliant, and high-quality energy efficiency upgrades.

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.
