Get started21 Brunswick Close is a three-bedroom end-of-terrace house in Biggleswade (SG18 0DA). It has a recorded floor area of 104 m² (around 1119 sq ft), construction records dating it to 1983-1990 and council tax band C. The latest certificate (December 2025) shows a D (score 63), on the cusp of jumping into the C band. When first surveyed in August 2015 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, hot-water efficiency went from Average to Good and lighting went from Very Poor to Good. This certificate was lodged in the last six months, so the rating reflects current condition. Other recorded features include a conservatory. Records show the property has been extended at some point in its history. The home occupies a corner plot.
At 104 m² the property is well over the postcode median (78 m² across 9 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £384,000 sits 50.6% above the 2015 sale of £255,000. On a £-per-square-foot basis, the last sale (£228/sq ft) was about 15.7% above the typical sold price in the postcode. Last sold in December 2015, so it's been off the market for around 10 years.
