Overview

About 15 Caspian Close

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

15 Caspian Close is a two-bedroom semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0BQ). It has a recorded floor area of 54 m² (around 581 sq ft), construction records dating it to 1983-1990 and council tax band B. The latest certificate (May 2014) shows a D (score 56), a step below the typical UK home. The recommended improvements would push it to C (score 80). The latest certificate is from May 2014, so improvements made since then won't be reflected. Other recorded features include attached land beyond the plot. Our model identifies extension potential, subject to local planning policy.

One planning record on file: an extension approved in 2022. Past consents include an extension, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Today's modelled estimate of £211,000 is 13.4% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£320/sq ft) was about 90.5% above the typical sold price in the postcode. Sold May 2022 for £186,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.

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 15 Caspian Close is modelled from its 54 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 0BQ. 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 15 Caspian Close. 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 15 Caspian Close 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 15 Caspian Close. 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 CF3 0BQ.
Council tax band
15 Caspian Close is in council tax band B. 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.
