Draught-proofing for Winchester properties
Our Hampshire coverage takes in Winchester (SO23) and nearby Eastleigh, Southampton and Totton. It is around 12 miles north of Southampton.
In Winchester homes this is often done on the same visit as a cavity fill, which saves a second trip. Small measures like this are often among the cheapest per pound saved, and they suit Winchester homes of every age.
As for paperwork, if cavity wall insulation follows in Winchester, 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.

Ventilation still matters
Trickle vents, air bricks and extractor fans are there for a reason. We seal accidental gaps, not the ventilation your home needs to keep condensation down.
