Flat 89, 26 High Street, Slough, SL1 1ER
About Flat 89
Flat 89 is a one-bedroom end-of-terrace house in Slough (SL1 1ER). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to 2007-2011 and council tax band C. At 56 m² this is the 37th smallest of 77 units on EPC record in the building, where floor areas span 43–119 m². The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (October 2025) shows a D (score 67), on the cusp of jumping into the C band. Earlier certificates rated it C (November 2011); the latest reading is one band lower. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would push it to C (score 69). Main heating runs on electricity.
It hasn't traded since November 2007, a hold of 19 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. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £196,000 is 21.4% above the 2007 sale price.
