Why Choose Our HMO Insulation & Retrofit Services?

Based in Ferndale, Global Energy Insulation provides fully compliant PAS 2035 HMO insulation solutions across South Wales and the South West. We help landlords meet strict MEES deadlines, improve EPC ratings, and resolve severe heat loss and thermal bridging issues. Working seamlessly alongside our sister company, Global Plastering, we deliver a comprehensive, end-to-end service—from accredited solid wall insulation to pristine traditional plastering finishes.

Meeting Compliance and EPC Requirements

Navigating the complexities of rental property regulations can be challenging, but our PAS 2035 compliant retrofit services are designed to simplify the process. Whether your property requires a formal retrofit assessment or specific wall treatments to address thermal bridging and condensation issues, we ensure that every installation meets current building regulations. We provide end-to-end support for landlords, helping you move from lower energy ratings to a compliant standard that meets legal requirements. Our expertise in non-traditional construction and historic building styles ensures that your insulation project respects the character of your property while delivering modern energy performance.

Why Partner with Global Energy Insulation

As a PAS 2030 accredited company, we prioritise safety, quality, and professionalism on every project in Treharris. We are fully CHAS accredited, hold a valid waste carriers licence, and provide SWIGA-backed insurance guarantees to protect your investment. Beyond our technical insulation work, we offer a unique advantage through our sister company, Global Plastering. This allows us to handle both the structural energy upgrades and the final internal finishes seamlessly, saving you the hassle of coordinating multiple contractors. Our team acts as your single point of contact for a complete, high-quality transformation of your HMO property.

Solving Common HMO Damp and Condensation Issues

HMOs with high occupancy levels often struggle with moisture control, leading to black mould and persistent damp that can deter tenants and damage property structures. Our insulation methods, particularly external wall insulation, significantly reduce thermal bridging and cold spots on internal surfaces. By wrapping your building in a high-performance thermal barrier, we raise the internal surface temperature of walls, effectively preventing condensation from forming. This not only creates a healthier home for your tenants but also significantly reduces the risk of long-term structural repair costs associated with damp-related decay.

HMO Insulation FAQ

Frequently Asked Questions

Answers to common questions from landlords about our HMO insulation, EPC rating improvements, and MEES compliance services in South Wales and South West England, South Wales, and the South West.

How long does it take to insulate an HMO?

+

The timeframe depends on the size of the property and the system used. External Wall Insulation for a standard terraced HMO usually takes 2 to 3 weeks, including the rendering finish. Internal work can be done room-by-room to minimise the impact on tenants.

Will EWI make the rooms smaller?

+

No. One of the biggest benefits of External Wall Insulation is that it is applied to the outside of the building. This is ideal for HMOs because you keep your exact room measurements, which is crucial for meeting local authority room size requirements.

How much can I improve my EPC rating?

+

It is common to see a property jump two full bands (e.g., from an E to a C) after professional wall insulation and loft upgrades. This not only makes the property legal to let but significantly increases its market value.

What is thermal bridging and why does it matter?

+

Thermal bridging happens when a "bridge" is created that allows heat to bypass insulation—often around windows, doors, or where walls meet floors. In HMOs, these cold spots are where mould usually starts. Our PAS 2035 approach ensures these bridges are closed, protecting the health of your tenants and your walls.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under permitted development. However, if your HMO is in a conservation area or is a listed building, you will need to check with your local council. We can help guide you through this process to ensure everything is done correctly.
