Overview

About Chelsea House

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

Chelsea House is a one-bedroom mid-terrace house in Milton Keynes (MK9 2BU). It has a recorded floor area of 50 m² (around 538 sq ft), construction records dating it to 2007-2011 and council tax band B. The latest certificate (September 2023) returns a B (score 82), comfortably above the UK average. When first surveyed in May 2013 the rating was C, the property has climbed 1 band since. Between certificates, lighting went from Average to Very Good. At 50 m² this is the 20th smallest of 48 units on EPC record in Chelsea House, where floor areas span 42–85 m². The building's EPC ratings span C to B, with this unit at the top.

It hasn't traded since October 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £144,000 is 26.3% above the 2007 sale price.

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 Chelsea House is modelled from its 50 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in MK9 2BU. 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 Chelsea House. 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 Chelsea House was lodged in September 2023 at band B and is valid until September 2033. 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 Chelsea 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
Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. The 30 schools and 30 stops listed are measured in a straight line from MK9 2BU, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
Chelsea House 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.
