How the estimate is made

The estimate for 21 Admiralty Tower is modelled from its 63 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in PO1 3GA. 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.

Overview

About 21 Admiralty Tower

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

21 Admiralty Tower is a one-bedroom semi-detached house in Portsmouth (PO1 3GA). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 2003-2006 and council tax band C. The latest certificate (February 2019) shows a C (score 80), near the top of the C band. Earlier certificates rated it B (February 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Good; while hot-water efficiency dropped from Average to Poor. The recommended improvements would push it to B (score 84). Main heating runs on electricity. At 63 m² this is the 31st smallest of 62 units on EPC record in the building, where floor areas span 27–93 m². The building's EPC ratings span D to B across 62 units on file. Other recorded features include a balcony and notable views.

It hasn't traded since January 2009, a hold of 18 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £172,000 is 22.9% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£206/sq ft) was about 42.2% below the postcode norm.

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 21 Admiralty Tower is modelled from its 63 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in PO1 3GA. 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 21 Admiralty Tower. 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 21 Admiralty Tower was lodged in February 2019 at band C and is valid until February 2029. 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 21 Admiralty Tower. 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 14 months, which places each incident at an approximate point. The 31 schools and 30 stops listed are measured in a straight line from PO1 3GA, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Admiralty Tower 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.
