About 21 Clare Avenue
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Clare Avenue is a three-bedroom detached house in Darlington (DL3 8SJ). It has a recorded floor area of 97 m² (around 1044 sq ft), construction records dating it to 1967-1975 and council tax band D. Other recorded features include attached land beyond the plot. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (September 2013) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from September 2013, so improvements made since then won't be reflected.
4 planning records sit against the property, 4 approved, 0 refused. Past consents include an extension, a garage conversion and a porch, meaningful when judging how the property has evolved. Across 2016–2023, sale prices on this property compounded at 1.9% per year. On a £-per-square-foot basis, the last sale (£254/sq ft) was about 53.1% above the typical sold price in the postcode. At 97 m² it's 24.2% smaller than the typical home in the postcode (128 m² median across 12 EPCs). Most recent transfer: May 2023 at £265,000.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 21 Clare Avenue is modelled from its 97 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in DL3 8SJ. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 21 Clare Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 21 Clare Avenue was lodged in September 2013 at band D and expired in September 2023, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 4 applications are matched to 21 Clare Avenue. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. The 20 schools and 30 stops listed are measured in a straight line from DL3 8SJ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21 Clare Avenue is in council tax band D. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
