Overview

About 15 Castlebay Court

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

15 Castlebay Court is a three-bedroom semi-detached house in Darlington (DL1 3RF). It has a recorded floor area of 71 m² (around 764 sq ft), construction records dating it to 1967-1975 and council tax band B. Tenure is freehold. The latest certificate (December 2014) shows a D (score 59), a step below the typical UK home. When first surveyed in April 2012 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Poor to Good; while roof efficiency dropped from Poor to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from December 2014, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.

Today's modelled estimate of £154,000 is 26.2% above the 2019 sale price. Last sale on file: £122,000 in March 2019.

Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 15 Castlebay Court is modelled from its 71 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 15 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 15 Castlebay Court was lodged in December 2014 at band D and expired in December 2024, 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. None is matched to 15 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
15 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.
