Overview

About 25 Clos Helyg

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

25 Clos Helyg is a semi-detached house in Gowerton, Swansea, Swansea (SA4 3GH). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 1996-2002 and council tax band D. The latest certificate (May 2013) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from May 2013, so improvements made since then won't be reflected.

Across 1999–2014, sale prices on this property compounded at 4.8% per year. Today's modelled estimate of £254,000 sits 81.4% above the 2014 sale of £140,000. On a £-per-square-foot basis, the last sale (£169/sq ft) was about 57.9% above the typical sold price in the postcode. Last sold in February 2014, so it's been off the market for around 13 years.

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 25 Clos Helyg is modelled from its 77 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA4 3GH. 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 25 Clos Helyg. 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 25 Clos Helyg was lodged in May 2013 at band D and expired in May 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 25 Clos Helyg. 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 SA4 3GH.
Council tax band
25 Clos Helyg is in council tax band D. 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.
