About 18 Blackoak Road
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
18 Blackoak Road is a three-bedroom semi-detached house in Cardiff (CF23 6QT). It has a recorded floor area of 106 m² (around 1141 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (December 2014) shows a D (score 62), on the cusp of jumping into the C band. When first surveyed in November 2014 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Very Poor to Poor; while lighting dropped from Average to Poor. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from December 2014, so improvements made since then won't be reflected. Other recorded features include a conservatory. Period features are noted in the property record.
Today's modelled estimate of £442,000 sits 52.4% above the 2015 sale of £289,950. On a £-per-square-foot basis, the last sale (£254/sq ft) was about 19.4% below the postcode norm. One planning record on file: an extension approved in 2016. Past consents include an extension, meaningful when judging how the property has evolved. On the market in February 2015 and unlisted since — roughly 12 years.

Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 18 Blackoak Road is modelled from its 106 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 6QT. 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 18 Blackoak Road. 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 18 Blackoak Road was lodged in December 2014 at band D and expired in December 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. 1 application is matched to 18 Blackoak Road. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
