About 101b
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
101b is a detached house in Cosham, Portsmouth, Portsmouth (PO6 3AZ). It has a recorded floor area of 81 m² (around 872 sq ft) and construction records dating it to 1930-1949.

Today's modelled estimate of £187,000 is 16.9% below the 2021 sale of £225,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£258/sq ft) was about 44.6% above the typical sold price in the postcode. At 81 m² the property is well over the postcode median (55 m² across 13 EPCs), placing it in the larger end of the local stock. Sold September 2021 for £225,000.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 101b is modelled from its 81 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in PO6 3AZ. 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 101b. 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 101b was lodged in December 2024 at band D and is valid until December 2034. 4 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 101b. 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 16 months, which places each incident at an approximate point. The 25 schools and 30 stops listed are measured in a straight line from PO6 3AZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
