Get started10 Mildmay Street is a four-bedroom semi-detached house in Winchester (SO22 4BX). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to 1950-1966 and council tax band C.

Between certificates, roof efficiency went from Poor to Very Good; while lighting dropped from Good to Average. The recommended improvements would push it to C (score 76). This certificate was lodged in the last six months, so the rating reflects current condition.
