Overview

About Penn Cottage

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

Penn Cottage is a three-bedroom detached house in Cock Clarks, Chelmsford, Chelmsford (CM3 6RE). It has a recorded floor area of 79 m² (around 850 sq ft) and construction records dating it to 1976-1982. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. Records show the property has been extended at some point in its history. The latest certificate (June 2014) shows a G (score 12), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 70), a 4-band jump. Main heating runs on electricity. The latest certificate is from June 2014, so improvements made since then won't be reflected.

Across 2000–2023, sale prices on this property compounded at 13% per year. Today's modelled estimate of £538,000 is 15.9% below the 2023 sale of £640,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£753/sq ft) was about 157.7% above the typical sold price in the postcode. At 79 m² it sits well below the postcode median (146 m² across 22 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Most recent transfer: March 2023 at £640,000. Across the public record there are 5 sales, relatively high churn for a single property. 10 planning records sit against the property, 7 approved, 2 refused. Past consents include an extension, a garage conversion and tree works, meaningful when judging how the property has evolved.

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 Penn Cottage is modelled from its 79 m² EPC floor area, its 5 recorded sales and recent sales of comparable homes in CM3 6RE. 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. 5 sales are recorded for Penn Cottage. 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 Penn Cottage was lodged in June 2014 at band G and expired in June 2024, 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. 10 applications are matched to Penn Cottage. 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 12 months, which places each incident at an approximate point. The 2 schools and 20 stops listed are measured in a straight line from CM3 6RE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
