Get started25 Haig Drive is a three-bedroom semi-detached house in Slough (SL1 9HA). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (February 2026) shows a C (score 71). When first surveyed in September 2015 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Poor to Average and hot-water efficiency went from Poor to Good. This certificate was lodged in the last six months, so the rating reflects current condition. Other recorded features include a conservatory. Our model identifies extension potential, subject to local planning policy.
It hasn't traded since July 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £415,000 sits 315% above the 1999 sale of £100,000. On a £-per-square-foot basis, the last sale (£129/sq ft) was about 54.1% below the postcode norm. At 72 m² it's 18% larger than the typical home in the postcode (61 m² median across 21 EPCs).
The EPC has just been inspected, so the rating reflects current condition.
25 Haig Drive's modelled value sits at over four times its earliest registered sale price (1999).
