About 3 Castlebay Court
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
3 Castlebay Court is a two-bedroom end-of-terrace house in Darlington (DL1 3RF). It has a recorded floor area of 76 m² (around 818 sq ft), construction records dating it to 1996-2002 and council tax band B. The latest certificate (February 2013) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since January 2012. Between certificates, roof efficiency went from Good to Very Good; while lighting dropped from Good to Poor. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from February 2013, so improvements made since then won't be reflected.
Untraded for 30 years, with the last transfer in June 1996. 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 £139,000 sits 215.9% above the 1996 sale of £44,000. On a £-per-square-foot basis, the last sale (£54/sq ft) was about 64.5% below the postcode norm. One planning record on file: an extension approved in 2016. Past consents include an extension and a garage conversion, meaningful when judging how the property has evolved. At 76 m² it's 16% larger than the typical home in the postcode (66 m² median across 12 EPCs).

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 3 Castlebay Court is modelled from its 76 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in DL1 3RF. 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. 1 sale is recorded for 3 Castlebay Court. 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 3 Castlebay Court was lodged in February 2013 at band D and expired in February 2023, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 3 Castlebay Court. 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 17 months, which places each incident at an approximate point. The 13 schools and 30 stops listed are measured in a straight line from DL1 3RF, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 3 Castlebay Court is in council tax band B. 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.
