Underfloor insulation for Cramlington properties
Cramlington is among the towns we cover in Northumberland, alongside Blyth, Ashington and Morpeth. It is about 4 miles south-west of Blyth.
In Cramlington homes this is often done on the same visit as a cavity fill, which saves a second trip. We check ventilation as carefully as insulation in Cramlington homes, because both matter for keeping a house dry.
For regulations, if cavity wall insulation follows in Cramlington, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
What is included in Cramlington
- Draught sealing at skirtings
