Overview

About 17a

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

17a is a four-bedroom detached house in Penylan, Cardiff, Cardiff (CF23 9DT). It has a recorded floor area of 173 m² (around 1862 sq ft), construction records dating it to 1900-1929 and council tax band H. The latest certificate (May 2013) shows a D (score 56), a step below the typical UK home. When first surveyed in May 2013 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor, hot-water efficiency went from Very Poor to Good and lighting went from Very Poor to Average. The recommended improvements would push it to C (score 74). The latest certificate is from May 2013, so improvements made since then won't be reflected.

Today's modelled estimate of £789,000 sits 66.1% above the 2015 sale of £475,000. On a £-per-square-foot basis, the last sale (£255/sq ft) was about 16.2% below the postcode norm. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). Last sold in March 2015, so it's been off the market for around 11 years.

Method

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 17a is modelled from its 173 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 9DT. 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 17a. 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 17a 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 17a. 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 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF23 9DT.
Council tax band
17a 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.
