Overview

About 14 Glenroy Avenue

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

14 Glenroy Avenue is a semi-detached house in St. Thomas, Swansea, Swansea (SA1 8DU). It has a recorded floor area of 80 m² (around 861 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (July 2013) shows a D (score 60), on the cusp of jumping into the C band. Earlier certificates rated it C (June 2013); the latest reading is one band lower. Between certificates, wall efficiency dropped from Good to Poor and roof efficiency dropped from Very Good to Good. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from July 2013, so improvements made since then won't be reflected.

Untraded for 28 years, with the last transfer in July 1998. 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 £161,000 sits 305% above the 1998 sale of £39,750. On a £-per-square-foot basis, the last sale (£46/sq ft) was about 64% below the postcode norm.

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 14 Glenroy Avenue is modelled from its 80 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 8DU. 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 14 Glenroy 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 14 Glenroy Avenue was lodged in July 2013 at band D and expired in July 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 14 Glenroy 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. Schools and stops are measured in a straight line from SA1 8DU.
Council tax band
14 Glenroy Avenue is in council tax band C. 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.
