Overview

About 12 Granville Avenue

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

12 Granville Avenue is a semi-detached house in Cardiff (CF5 1BW). It has a recorded floor area of 109 m² (around 1173 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (February 2014) shows an E (score 41), well below the UK norm with real room to improve. The rating has held steady at E across 4 certificates since April 2009. Between certificates, lighting went from Average to Good and main heating went from Average to Good; while roof efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 81), a 3-band jump. The latest certificate is from February 2014, so improvements made since then won't be reflected.

Held since September 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £466,000 sits 86.4% above the 2009 sale of £250,000. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).

Valuation method in detail
How the estimate is made
The estimate for 12 Granville Avenue is modelled from its 109 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF5 1BW. 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 12 Granville 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 12 Granville Avenue was lodged in February 2014 at band E and expired in February 2024, so a new one is needed to sell or let. 4 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 12 Granville 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 CF5 1BW.
