Current guidance is 270 mm of mineral wool for lofts to achieve recommended U-values.

Yes—our trained team uses specialist equipment and provides a completion certificate.

Most homes are completed within 2–4 hours depending on loft size and access.

Yes, we estimate EPC gains and annual energy savings during the survey.

Absolutely. We use high-performance Knauf boards for solid-wall properties.

If contamination is present, full removal and chemical decontamination are recommended.

Yes—we maintain fire-safe clearances and use protective covers where required.

Yes—a 10% labour discount for military, blue-light workers and OAPs.

Surveys are usually available within 3–5 working days across Yorkshire.

Bank transfer, card, cash and Clearpay up to £1000 (10% fee applies).

Yes—high-performance boards stabilise temperatures year-round.

Most lenders require joists to be visible, so removal is usually mandatory.

Typically 100–200 mm depending on existing depth to reach 270 mm total.

Yes, all old insulation is bagged and disposed of responsibly.

We use Knauf products which are 97% recyclable and use bio-based binders.

Every removal, relay or top-up comes with a signed completion certificate.

Yes—it improves both thermal and acoustic performance.

No, all work is completed to manufacturer guidelines and building regs.

Yes—every survey includes a no-obligation free quote.

Yes—we carry full public liability insurance and our staff are fully trained.

Upgrading insulation reduces heat loss and lowers annual energy demand. An EPC survey measures U-values and heating costs, so better insulation directly raises the letter grade, often unlocking better mortgage rates.

Yes—our team uses compact equipment and safety platforms to remove or install insulation even in tight spaces, ensuring every corner meets the 270 mm requirement.

Every survey includes a moisture reading and visual inspection to detect condensation, leaks or timber rot before installation begins.

When correctly detailed with vapour control layers, IWI reduces rather than causes condensation. We always install a moisture barrier and maintain ventilation pathways.

A full measurement of loft or wall areas, moisture check, thickness readings, photographic documentation and a fixed-price written quote with recommendations for savings.

Noise and dust are minimal thanks to sealed containment, HEPA filtration and daily clean-downs. Most removals are completed within 1–2 days depending on loft size.

Yes—as long as the existing material is dry and structurally sound. We vacuum loose dust and add mineral wool layers to reach the target depth.

Knauf mineral wool typically performs for 40+ years with no loss of thermal value, provided ventilation is maintained and the loft remains dry.

All removed insulation is bagged, transported and recycled or disposed of in licensed facilities, and we provide proof of safe disposal on request.

Absolutely—many customers book a spray foam removal, loft hoover, and full relay in a single project to save time and reduce overall labour costs.
