About Capel House

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

Capel House is a detached house in Capel Llanilltern, Cardiff, Cardiff (CF5 6HF). It has a recorded floor area of 242 m² (around 2605 sq ft) and construction records dating it to before 1900. The latest certificate (July 2015) shows a G (score 5), near the bottom of the EPC scale. Earlier certificates rated it F (May 2014); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would lift it to D (score 61), a 3-band jump. Main heating runs on lpg. The latest certificate is from July 2015, so improvements made since then won't be reflected.

How to read this page

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 Capel House is modelled from its 242 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in CF5 6HF. 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. No sale is recorded for Capel House, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 Capel House was lodged in July 2015 at band G and expired in July 2025, 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. 3 applications are matched to Capel House. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
