Why Choose Our Loft Insulation Services in South Wales?

Why is proper loft insulation essential for your Swansea property?

Heat naturally rises, and without adequate thermal barriers in your loft space, your heating system works much harder than it needs to. Many older properties in Abertawe, including traditional Victorian terraces and non-traditional builds like Airey or Cornish units, suffer from poor thermal retention. Our PAS 2035 compliant approach ensures we identify the root cause of your heat loss, providing a tailored insulation solution that stops cold draughts and creates a more comfortable living environment year-round.

Our expert installation process and PAS 2035 compliance

We take a systematic approach to every project, starting with a comprehensive survey to assess your existing loft conditions. If your loft contains old or damp insulation, our team of licensed waste carriers will professionally remove it, ensuring the space is clean and prepped for the new material. We install premium Earthwool, cross-laying the rolls to reach the recommended 270mm depth. This method eliminates thermal bridging and provides consistent coverage across your entire ceiling joists. As part of the service, we also insulate your loft hatch and provide pipework lagging to prevent freezing and further heat loss.

Benefits for landlords and homeowners in Abertawe

Investing in professional loft insulation does more than just lower your monthly energy costs. By upgrading your insulation, you significantly boost your property's EPC rating, which is critical for landlords looking to meet current MEES requirements. Whether you own a detached family home, a bungalow, or an office space, our insulation solutions provide a long-term return on investment. Our work is fully backed by our PAS 2030 accreditation, meaning you can trust in the quality and safety of every install.

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!"

Loft Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited loft insulation services. Discover how we eliminate draughts, reduce heat loss, and improve EPC ratings across South Wales and South West England, South Wales, and South West England.

How thick should my loft insulation be to save money?

+

To meet current UK building regulations and get the best results for your energy bills, we recommend a total thickness of 270mm. If you already have some insulation but it's thin or old, we can "top it up" to reach this standard, which makes a massive difference to heat loss reduction.

Can I still use my loft for storage after it is insulated?

+

Yes, but you shouldn't squash the insulation down with boxes, as this stops it from working. We can install loft legs or a raised boarding system. This allows the insulation to sit at the full 270mm depth while giving you a sturdy, flat platform for your belongings.

How long does it take to install?

+

For most standard homes, like a three-bedroom semi-detached in Ferndale, we can usually finish the job in just a few hours. It is one of the least invasive home improvements you can do, and we make sure all mess is cleared away before we leave.

Will loft insulation cause damp or condensation?

+

Only if it is installed poorly. We make sure that your roof eaves are kept clear so that air can still flow through the loft space. This is why professional installation is so important—we balance thermal comfort with proper ventilation to protect your roof timbers from rot.

Is there help available for the cost of insulation?

+

There are often various grants and schemes available, such as ECO4, particularly for low-income households or properties with low EPC ratings. As PAS 2030 accredited installers, we stay up to date with these schemes and can advise you on whether your project might qualify for funding.
