About 21 Dyfed Avenue

21 Dyfed Avenue is a four-bedroom semi-detached house in Townhill, Swansea, Swansea (SA1 6NP). It has a recorded floor area of 111 m² (around 1195 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (March 2014) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in February 2012 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Poor to Good; while roof efficiency dropped from Very Good to Very Poor and lighting dropped from Very Good to Good. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from March 2014, so improvements made since then won't be reflected.

How to read this page

Valuation method in detail
How the estimate is made
The estimate for 21 Dyfed Avenue is modelled from its 111 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 6NP. 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 Dyfed 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 21 Dyfed Avenue was lodged in March 2014 at band D and expired in March 2024, 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. 3 applications are matched to 21 Dyfed 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 6NP.
Council tax band
21 Dyfed Avenue 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.
