About Flat 11

Between certificates, wall efficiency went from Very Poor to Poor and lighting went from Very Poor to Very Good. The recommended improvements would push it to C (score 76).

Most recent transfer: September 2022 at £105,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include subdivision and change of use to residential, meaningful when judging how the property has evolved. Today's modelled estimate of £118,000 is 12.4% above the 2022 sale price.
