Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Letchworth Garden City properties, so you can choose who fixes them.

Every elevation is judged on its own exposure. Much of Hertfordshire 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, if cavity wall insulation follows in Letchworth Garden City, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
