Overview

About 18 Allens Avenue

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

18 Allens Avenue is a three-bedroom semi-detached house in Norwich (NR7 8EP). It has a recorded floor area of 98 m² (around 1055 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (July 2014) shows an E (score 42), 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 July 2014, so improvements made since then won't be reflected. Period features are noted in the property record. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility.

It hasn't traded since January 2001, a hold of 26 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £285,000 sits 239.3% above the 2001 sale of £84,000. On a £-per-square-foot basis, the last sale (£80/sq ft) was about 55.1% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 81% of similar EPCs).

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 18 Allens Avenue is modelled from its 98 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in NR7 8EP. 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 18 Allens Avenue. 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 18 Allens Avenue was lodged in July 2014 at band E and expired in July 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. None is matched to 18 Allens Avenue. 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 13 months, which places each incident at an approximate point. The 26 schools and 1 stop listed are measured in a straight line from NR7 8EP, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 Allens Avenue 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.
