Blown mineral wool insulation for Witney properties
If your property is in Witney or the OX28 district or nearby Oxford, Abingdon and Didcot, it is within our Oxfordshire coverage. It is about 10 miles west of Oxford.
For semi-detached and terraced homes in Witney, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. If a wall in Witney is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Local weather affects which walls can be filled. 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.
For regulations, in Witney 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.

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
