Overview

About Old Wallace Farm

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

Old Wallace Farm is a detached house in Dyffryn, Cardiff, Cardiff (CF5 6SU). It has a recorded floor area of 279 m² (around 3003 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (May 2013) shows a D (score 68), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since March 2013. The recommended improvements would lift it to A (score 95), a 3-band jump. Main heating runs on oil. The latest certificate is from May 2013, so improvements made since then won't be reflected.

Valuation method in detail
How the estimate is made
The estimate for Old Wallace Farm is modelled from its 279 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF5 6SU. 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 Old Wallace Farm. 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 Old Wallace Farm was lodged in May 2013 at band D and expired in May 2023, 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 Old Wallace Farm. 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 CF5 6SU.
Council tax band
Old Wallace Farm is in council tax band H. 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.
