Cavity insulation top-up for Hull properties
Hull sits in the East Riding of Yorkshire. We work across the HU1 district, including nearby Beverley, Goole and Bridlington.
For semi-detached and terraced homes in Hull, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. A suitable wall in Hull is usually filled in a single day from outside, with drill holes made good to match the pointing.
Every elevation is judged on its own exposure. Much of the East Riding of Yorkshire 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.
On compliance, in Hull 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 a top-up is not enough
If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
