Overview

About 9 Byron House

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

9 Byron House is a one-bedroom property in Cambridge (CB1 1AN). It has a recorded floor area of 39 m² (around 420 sq ft), construction records dating it to 2012 onwards and council tax band B. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a balcony. At 39 m² this is the 12th smallest of 14 units on EPC record in the building, where floor areas span 32–50 m². The building's EPC ratings span D to B across 14 units on file. The latest certificate (May 2026) shows a C (score 78), near the top of the C band. The rating has held steady at C across 2 certificates since October 2011. Between certificates, hot-water efficiency went from Poor to Good and main heating went from Very Poor to Poor; while wall efficiency dropped from Very Good to Good and window efficiency dropped from Good to Average. The recommended improvements would push it to B (score 85). Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.

Last sold in February 2012, so it's been off the market for around 14 years. Today's modelled estimate of £241,000 is 30.3% above the 2012 sale price.

How to read this page

Valuation method in detail
How the estimate is made
The estimate for 9 Byron House is modelled from its 39 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CB1 1AN. 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 9 Byron 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 9 Byron House was lodged in May 2026 at band C and is valid until May 2036. 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 9 Byron 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 17 months, which places each incident at an approximate point. The 26 schools and 3 stops listed are measured in a straight line from CB1 1AN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
9 Byron 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.
