21 Britannia Avenue, Luton, LU3 1XD

21 Britannia Avenue is a three-bedroom mid-terrace house in Luton (LU3 1XD). It has a recorded floor area of 100 m² (around 1081 sq ft), construction records dating it to 1930-1949 and council tax band B. The latest certificate (July 2011) shows a C (score 69), just inside the C band. When first surveyed in August 2010 the rating was F, the property has climbed 3 bands since. Between certificates, hot-water efficiency went from Poor to Good and main heating went from Poor to Good. The latest certificate is from July 2011, so improvements made since then won't be reflected.

Held since December 2010 — that's 16 years off the open market, well above the local norm. At 100 m² the property is well over the postcode median (75 m² across 22 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 82% of similar EPCs). Today's modelled estimate of £253,000 sits 98.4% above the 2010 sale of £127,500. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 38.1% below the postcode norm. One planning record on file: an extension approved in 2017. Past consents include an extension, meaningful when judging how the property has evolved.
