About The Annexe

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

The Annexe is a property in Redbourn, St. Albans, St Albans (AL3 7AS). It has a recorded floor area of 49 m² (around 527 sq ft) and council tax band A. The latest certificate (November 2015) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. Main heating runs on electricity: electricity, unspecified tariff. The latest certificate is from November 2015, so improvements made since then won't be reflected.

Today's modelled estimate of £726,000 is 33.5% below the 2025 sale of £1,092,500, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. Most recent transfer was December 2025 at £1,092,500 — fresh data.
