Overview

About 15a

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

15a is a detached house in West Mersea, Colchester, Colchester (CO5 8BG). It has a recorded floor area of 198 m² (around 2130 sq ft), construction records dating it to 2003-2006 and council tax band G. The latest certificate (June 2011) shows a C (score 71). The latest certificate is from June 2011, so improvements made since then won't be reflected.

It hasn't traded since December 1996, a hold of 30 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 198 m² the property is well over the postcode median (150 m² across 20 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 70% of similar EPCs). Today's modelled estimate of £711,000 sits 330.9% above the 1996 sale of £165,000.

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 15a is modelled from its 198 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CO5 8BG. 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 15a. 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 15a was lodged in June 2011 at band C and expired in June 2021, 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 15a. 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 15 months, which places each incident at an approximate point. The 1 school and 18 stops listed are measured in a straight line from CO5 8BG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
15a is in council tax band G. 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.
