How the estimate is made

About 23 Clos Derwen
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
23 Clos Derwen is a four-bedroom detached house in Cardiff (CF23 5HJ). It has a recorded floor area of 125 m² (around 1345 sq ft), construction records dating it to 1996-2002 and council tax band G. The latest certificate (May 2014) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected.
Untraded for 26 years, with the last transfer in April 2000. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £578,000 sits 207.5% above the 2000 sale of £187,950. On a £-per-square-foot basis, the last sale (£140/sq ft) was about 35.1% below the postcode norm. One planning record on file: an extension approved in 2015. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.

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 23 Clos Derwen is modelled from its 125 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 5HJ. 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 23 Clos Derwen. 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 23 Clos Derwen was lodged in May 2014 at band D and expired in May 2024, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 23 Clos Derwen. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
