Overview

About 16 Arethusa House

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

16 Arethusa House is a two-bedroom mid-terrace house in Portsmouth (PO1 3TQ). It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to 1996-2002 and council tax band E. The latest certificate (January 2020) shows a D (score 68), on the cusp of jumping into the C band. Earlier certificates rated it C (November 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Very Good; while hot-water efficiency dropped from Good to Poor and main heating dropped from Good to Very Poor. Main heating runs on electricity. At 81 m² this is the 15th smallest of 52 units on EPC record in the building, where floor areas span 59–171 m². The building's EPC ratings span E to B across 52 units on file. Other recorded features include a conservatory and outbuildings.

It hasn't traded since January 2007, a hold of 20 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs). Across 2002–2007, sale prices on this property compounded at 8.6% per year. Today's modelled estimate of £350,000 is 42.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£281/sq ft) was about 17.1% 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 16 Arethusa House is modelled from its 81 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in PO1 3TQ. 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. 2 sales are recorded for 16 Arethusa 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 16 Arethusa House was lodged in January 2020 at band D and is valid until January 2030. 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 16 Arethusa 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 14 months, which places each incident at an approximate point. The 28 schools and 30 stops listed are measured in a straight line from PO1 3TQ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
16 Arethusa House is in council tax band E. 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.
