Blown mineral wool insulation for Didcot properties

Didcot sits in Oxfordshire, around 10 miles south of Oxford. We work across the OX11 district, including nearby Abingdon, Oxford and Witney.

A suitable wall in Didcot is usually filled in a single day from outside, with drill holes made good to match the pointing. Where a Didcot property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.

Every elevation is judged on its own exposure. Much of Oxfordshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

In terms of approvals, in Didcot filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

Why choose mineral wool?

Mineral wool fibres are treated to shed water, so moisture that gets into the outer leaf runs down the cavity rather than tracking across. It is classed as non-combustible, which matters for some flats and taller buildings, and it is usually the lower-cost certified option.

What is included in Didcot
