11a, Brook Street, Luton, LU3 1DS

11a is a three-bedroom end-of-terrace house in Luton (LU3 1DS). It has a recorded floor area of 65 m² (around 700 sq ft), construction records dating it to 1967-1975 and council tax band A. At 65 m² this is the 45th smallest of 57 units on EPC record in the building, where floor areas span 26–170 m². The building's EPC ratings span E to B, with this unit at the bottom. The latest certificate (February 2014) shows an E (score 44), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 63). Main heating runs on electricity. The latest certificate is from February 2014, so improvements made since then won't be reflected.

It hasn't traded since April 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 65 m² it's 20.4% larger than the typical home in the postcode (54 m² median across 56 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £138,000 is 45.3% above the 2008 sale price.
