Overview

About 50 Derwen Road

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

50 Derwen Road is a four-bedroom detached house in Pontardawe, Swansea, Swansea (SA8 3AU). It has a recorded floor area of 224 m² (around 2411 sq ft), construction records dating it to 2007 onwards and council tax band G. The latest certificate (June 2016) returns a B (score 82), comfortably above the UK average. When first surveyed in September 2011 the rating was C, the property has climbed 1 band since. Between certificates, lighting went from Good to Very Good; while hot-water efficiency dropped from Good to Poor and main heating dropped from Good to Average. Main heating runs on electricity. The latest certificate is from June 2016, so improvements made since then won't be reflected. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal.

At 224 m² the property is well over the postcode median (106 m² across 33 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the top 10% of properties in this postcode. Today's modelled estimate of £515,000 is 14.4% above the 2023 sale price.

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 50 Derwen Road is modelled from its 224 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA8 3AU. 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 50 Derwen 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 50 Derwen Road was lodged in June 2016 at band B and expired in June 2026, so a new one is needed to sell or let. 5 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 50 Derwen 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 12 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA8 3AU.
Council tax band
50 Derwen Road is in council tax band G. 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.
