Overview

About 23 Sir Williams Close

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

23 Sir Williams Close is a three-bedroom detached house in Aylsham, Norwich, Norwich (NR11 6AP). It has a recorded floor area of 114 m² (around 1227 sq ft), construction records dating it to 1976-1982 and council tax band C. The latest certificate (April 2016) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from April 2016, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history. The home occupies a corner plot.

At 114 m² it's 23.9% larger than the typical home in the postcode (92 m² median across 30 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). Last sold in December 2016, so it's been off the market for around 10 years. Today's modelled estimate of £348,000 is 45% above the 2016 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 23 Sir Williams Close is modelled from its 114 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in NR11 6AP. 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 23 Sir Williams Close. 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 23 Sir Williams Close was lodged in April 2016 at band E and expired in April 2026, 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. None is matched to 23 Sir Williams Close. 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 4 schools and 1 stop listed are measured in a straight line from NR11 6AP, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
23 Sir Williams Close 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.
