What does it cost in Yorkshire and the Humber?
Our guide range for cavity wall insulation in Yorkshire and the Humber is £850–£2,500 per home. That is the UK range of £950–£2,700 (published figure) adjusted by a regional cost factor of 0.92 (VOA Rating Cost Guide 2026: 0.90–0.96); figures are before VAT where the source states it. Every job is priced after survey; specification, access and the condition of the homes will move the figure.
How do we deliver it?
Loft work includes checking that the eaves are still ventilating once the new insulation is down, because blocked eaves cause condensation in the roof space.
