Why Choose Our HMO Landlord EPC Upgrades?

Why PAS 2035 Compliance Matters for Your HMO

Meeting the new regulatory landscape requires more than just basic insulation. By following PAS 2035 standards, we ensure that your property retrofit is handled with professional rigour, focusing on ventilation and moisture control alongside thermal performance. Our PAS 2030 accredited team understands the unique challenges of HMO layouts, including Victorian terraces and non-traditional builds common across South Wales. We provide technical proficiency that ensures your investment is future-proofed against legislative changes.

Bespoke Insulation Solutions for Challenging Property Types

HMOs often feature complex structural elements that lead to significant heat loss and thermal bridging. We offer tailored external wall insulation, internal wall insulation, and loft upgrades designed to solve these issues. Whether your building is a classic terraced house or a modernised unit, our solutions help eliminate draughts and prevent the damp problems that often plague older properties. By addressing these weak points, we significantly improve tenant comfort and reduce energy bills.

Achieving EPC Band C and Protecting Your Investment

Upgrading to an EPC Band C is not just about compliance; it is about tenant retention and attracting higher-quality occupants who value warmth and low energy costs. Our services include everything from damp-aware plastering and silicone rendering to large-scale wall insulation projects. Every installation is supported by SWIGA insurance-backed guarantees, providing landlords in Treharris with the peace of mind that their property refurbishment is built to last.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

FAQ

Frequently Asked Questions

Answers to common questions about HMO EPC upgrades, MEES compliance, and our PAS 2035 retrofit services in South Wales and South West England.

What is the minimum EPC rating for HMOs in 2024?

+

Currently, the minimum standard is an E. However, the government has proposed that all new tenancies must reach a C by 2025/2026, with all existing tenancies hitting that mark by 2028-2030. Even if the deadlines shift slightly, the trend is clear: D and E rated properties will soon be unrentable legally.

How does External Wall Insulation help my EPC score?

+

In many older Ferndale properties, the walls are "solid," meaning they have no cavity to fill. These walls lose heat incredibly fast. EWI acts like a thermal tea cosy for your house. Because it is so effective at stopping heat loss, it is often the single biggest "point-scorer" on an EPC assessment for a Victorian or Edwardian building.

Do I need planning permission for EWI on my HMO?

+

In many cases, EWI falls under permitted development. However, if your property is in a conservation area or is a listed building, rules change. We can help you navigate this, and if you are in a terrace where EWI might change the look of the street, we can discuss finishes like brick-slips that mimic the original look while providing modern warmth.

Is Internal Wall Insulation a better option for HMOs?

+

IWI is great if you want to keep the external look of the building exactly as it is, or if planning rules prevent EWI. The downside is that it reduces the room's internal dimensions slightly. In an HMO, where room sizes are strictly regulated by the council, you have to be careful not to make a room too small to be legally let. We can advise on the thinnest, most efficient materials to prevent this.

How long does an energy retrofit take?

+

It depends on the size of the house, but a typical terraced HMO can usually be insulated and rendered externally in 2 to 3 weeks, depending on the weather. We work efficiently to make sure there is minimal disruption to your tenants.
