About 1 Carlbury Close
1 Carlbury Close is a two-bedroom end-of-terrace house in St Albans (AL1 5DR). It has a recorded floor area of 55 m² (around 592 sq ft), construction records dating it to 1996-2002 and council tax band D. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Our model identifies extension potential, subject to local planning policy. The home occupies a cul-de-sac position. The latest certificate (April 2026) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (July 2011); the latest reading is one band lower. Between certificates, lighting went from Average to Good; while main heating dropped from Average to Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs). Across 1997–2022, sale prices on this property compounded at 7.6% per year. On a £-per-square-foot basis, the last sale (£807/sq ft) was about 144.5% above the typical sold price in the postcode. Last sale on file: £477,500 in May 2022. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2014.
