Overview

About 18 Kilvey Terrace

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

18 Kilvey Terrace is a mid-terrace house in St. Thomas, Swansea, Swansea (SA1 8BA). It has a recorded floor area of 128 m² (around 1378 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (February 2013) shows an E (score 43), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since March 2010. Between certificates, window efficiency went from Average to Good; while lighting dropped from Poor to Very Poor. The recommended improvements would lift it to C (score 74), a 2-band jump. The latest certificate is from February 2013, so improvements made since then won't be reflected.

It hasn't traded since December 2006, a hold of 20 years that's notably long for the area. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs). Today's modelled estimate of £140,000 is 18.6% above the 2006 sale price.

Valuation method in detail
How the estimate is made
The estimate for 18 Kilvey Terrace is modelled from its 128 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 8BA. 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 18 Kilvey Terrace. 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 Kilvey Terrace was lodged in February 2013 at band E 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. None is matched to 18 Kilvey Terrace. 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. Schools and stops are measured in a straight line from SA1 8BA.
Council tax band
18 Kilvey Terrace 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.
