Meeting EPC Standards and Conservation Requirements

For landlords and homeowners in Crickhowell, meeting modern MEES standards and improving EPC ratings in a Grade II listed property can feel overwhelming. We remove the complexity by managing the compliance process for you. As PAS 2035 accredited experts, we are highly experienced in navigating the requirements for conservation areas. Whether you are dealing with a classic Victorian terrace, an Edwardian villa, or a traditional stone cottage, our retrofit solutions are designed to satisfy local authority regulations while significantly reducing your heat loss and energy bills.

How Our Breathable Insulation Retrofit Works

Our approach to retrofitting historic buildings prioritises building health. We avoid materials that might lead to dampness, instead opting for breathable insulation systems that allow the structure to regulate moisture naturally. Our process begins with a thorough survey to assess the thermal performance of your solid walls. Once the insulation is expertly installed, we coordinate with our sister company, Global Plastering, to apply authentic lime plaster finishes. This end-to-end service ensures that your walls not only perform thermally but also retain their authentic, period aesthetic.

Is Internal Wall Insulation Suitable for Your Heritage Home?

Many homeowners ask if it is possible to insulate a historic home without changing the exterior appearance. Internal wall insulation is often the ideal answer for listed buildings in Crickhowell where external cladding is not permitted. By applying specialised insulation layers to the internal face of your walls, we can transform a cold, draughty space into a comfortable, energy-efficient home. This method preserves your property's exterior stone or brickwork while providing a substantial increase in thermal retention and a notable reduction in your heating expenditure.

Heritage Property FAQs

Frequently Asked Questions

Answers to common questions about breathable historic building insulation, thermal bridging solutions, and PAS 2035 compliance across South Wales and South West England and South Wales.

Do I need planning permission to insulate my listed building in Ferndale?

+

Yes, in most cases, you will need Listed Building Consent for internal or external wall insulation. Because these works change the thickness of the walls or the materials used, local planning officers want to see that the heritage of the building is being protected. We can help provide the technical details needed for your application.

Why shouldn't I use cheap foam insulation on an old stone wall?

+

Old buildings were designed to be "breathable." Moisture travels through the stones and mortar and evaporates. If you put non-breathable foam against the wall, you trap that moisture. This leads to "interstitial condensation," which rots floor joists and causes damp patches. We use breathable wood fibre or mineral wool to keep your walls healthy.

Will I lose the original features like my coving or skirting boards?

+

We do everything we can to preserve the character of your home. Sometimes this involves carefully removing and reinstating skirting boards or using thinner, high-performance insulation in areas with intricate decorative features. Our partnership with Global Plastering allows us to replicate traditional finishes so your home looks exactly as it should—only warmer.

How long does it take to insulate a period property?

+

Every building is unique, but a typical internal wall insulation project for a terraced house usually takes between one and two weeks. This includes the preparation, the insulation fixings, and the specialist lime plastering finish.
