Overview

About 20 Catharine Street

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

20 Catharine Street is a three-bedroom semi-detached house in Cambridge (CB1 3AW). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (May 2021) shows a D (score 64), on the cusp of jumping into the C band. When first surveyed in May 2011 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Good to Very Good, window efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good. The recommended improvements would lift it to B (score 85), a 2-band jump. Other recorded features include a loft.

Held since September 2008 — that's 18 years off the open market, well above the local norm. Across the public record there are 4 sales, relatively high churn for a single property. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1996–2008, sale prices on this property compounded at 11.1% per year. Today's modelled estimate of £477,000 sits 94.7% above the 2008 sale of £245,000. One historical planning record sits against the property in 2019.

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 20 Catharine Street is modelled from its 74 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CB1 3AW. 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. 4 sales are recorded for 20 Catharine Street. 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 20 Catharine Street was lodged in May 2021 at band D and is valid until May 2031. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 20 Catharine Street. 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 17 months, which places each incident at an approximate point. The 30 schools and 2 stops listed are measured in a straight line from CB1 3AW, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
20 Catharine Street is in council tax band C. 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.
