About 10 Cwm Gwynlais

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

10 Cwm Gwynlais is a detached house in Tongwynlais, Cardiff, Cardiff (CF15 7HU). It has a recorded floor area of 123 m² (around 1324 sq ft), construction records dating it to 1991-1995 and council tax band F. The latest certificate (August 2014) shows an E (score 44), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since September 2013. Between certificates, roof efficiency went from Average to Good and window efficiency went from Average to Good; while wall efficiency dropped from Good to Poor.

Valuation method in detail
How the estimate is made
The estimate for 10 Cwm Gwynlais is modelled from its 123 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF15 7HU. 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 10 Cwm Gwynlais. 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 10 Cwm Gwynlais was lodged in August 2014 at band E and expired in August 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. None is matched to 10 Cwm Gwynlais. 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 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 7HU.
Council tax band
10 Cwm Gwynlais is in council tax band F. 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.
