Overview

About 12 Alexandra Avenue

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

12 Alexandra Avenue is a three-bedroom detached house in West Mersea, Colchester, Colchester (CO5 8BG). It has a recorded floor area of 171 m² (around 1841 sq ft), construction records dating it to 1930-1949 and council tax band F. There is a swimming pool on the plot, uncommon for the area.

When first surveyed in July 2014 the rating was G, the property has climbed 5 bands since. Between certificates, wall efficiency went from Very Poor to Very Good, roof efficiency went from Very Poor to Very Good and window efficiency went from Average to Good; while hot-water efficiency dropped from Good to Average. Main heating runs on oil. The latest certificate is from December 2015, so improvements made since then won't be reflected.

Today's modelled estimate of £689,000 sits 72.2% above the 2014 sale of £400,000. Last sold in December 2014, so it's been off the market for around 12 years.

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 12 Alexandra Avenue is modelled from its 171 m² EPC floor area, its 2 recorded sales 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. 2 sales are recorded for 12 Alexandra Avenue. 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 12 Alexandra Avenue was lodged in December 2015 at band B and expired in December 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. None is matched to 12 Alexandra Avenue. 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
12 Alexandra Avenue is in council tax band F. 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.
