Overview

About 6 Mill Road

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

6 Mill Road is a two-bedroom semi-detached house in Tongwynlais, Cardiff, Cardiff (CF15 7JP). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (July 2016) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from July 2016, so improvements made since then won't be reflected. Period features are noted in the property record.

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 6 Mill Road is modelled from its 74 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF15 7JP. 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. 3 sales are recorded for 6 Mill 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 6 Mill Road was lodged in July 2016 at band E and expired in July 2026, 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. None is matched to 6 Mill 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
Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 7JP.
Council tax band
6 Mill Road is in council tax band E. 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.
