About 18 Castle Mews
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
18 Castle Mews is a one-bedroom mid-terrace house in Wellingborough (NN8 1NX). It has a recorded floor area of 36 m² (around 388 sq ft), construction records dating it to 1983-1990 and council tax band A. The latest certificate (September 2024) shows a D (score 66), on the cusp of jumping into the C band. Earlier certificates rated it C (December 2008); the latest reading is one band lower. Between certificates, window efficiency dropped from Good to Average and main heating dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 84), a 2-band jump. Main heating runs on electricity. At 36 m² this is the 3rd smallest of 20 units on EPC record in the building, where floor areas span 35–55 m². The building's EPC ratings span E to C across 20 units on file.
It hasn't traded since January 2009, a hold of 18 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 1997–2009, sale prices on this property compounded at 8.1% per year. Today's modelled estimate of £100,000 sits 61.3% above the 2009 sale of £62,000. On a £-per-square-foot basis, the last sale (£160/sq ft) was about 23% above the typical sold price in the postcode. At 36 m² it's 23.4% smaller than the typical home in the postcode (47 m² median across 19 EPCs). 1 bedrooms is on the smaller side for this postcode, where 3 is the typical count.

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 18 Castle Mews is modelled from its 36 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN8 1NX. 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 18 Castle Mews. 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 18 Castle Mews was lodged in September 2024 at band D and is valid until September 2034. 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 18 Castle Mews. 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 15 months, which places each incident at an approximate point. The 19 schools and 30 stops listed are measured in a straight line from NN8 1NX, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 18 Castle Mews is in council tax band A. 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.
