Overview

About 21 Gwernfadog Road

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

21 Gwernfadog Road is a three-bedroom mid-terrace house in Ynysforgan, Swansea, Swansea (SA6 6RY). It has a recorded floor area of 76 m² (around 818 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (December 2013) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 88), a 2-band jump. The latest certificate is from December 2013, so improvements made since then won't be reflected.

Untraded for 17 years, with the last transfer in October 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £140,000 sits 62.8% above the 2009 sale of £86,000. On a £-per-square-foot basis, the last sale (£105/sq ft) was about 29.2% 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 21 Gwernfadog Road is modelled from its 76 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA6 6RY. 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 21 Gwernfadog Road. 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 21 Gwernfadog Road was lodged in December 2013 at band D and expired in December 2023, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 Gwernfadog Road. 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 14 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA6 6RY.
Council tax band
21 Gwernfadog Road 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.
