Flat 1, 18 Trinity Street, London, SE1 1DB

Flat 1 is a three-bedroom end-of-terrace house in London (SE1 1DB). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1950-1966 and council tax band C. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. At 66 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 61–66 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (August 2015) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.

At 66 m² the property is well over the postcode median (33 m² across 19 EPCs), placing it in the larger end of the local stock. Last sold in March 2016, so it's been off the market for around 10 years. Across the public record there are 4 sales, relatively high churn for a single property. Across 1998–2016, sale prices on this property compounded at 10.2% per year. On a £-per-square-foot basis, the last sale (£985/sq ft) was about 49.1% above the typical sold price in the postcode.
