About 99a
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
99a is a one-bedroom end-of-terrace house in Cosham, Portsmouth, Portsmouth (PO6 3AZ). It has a recorded floor area of 57 m² (around 614 sq ft), construction records dating it to 1900-1929 and council tax band A. At 57 m² this is the 10th smallest of 14 units on EPC record in the building, where floor areas span 49–84 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (March 2021) shows a C (score 69), just inside the C band. When first surveyed in December 2008 the rating was D, the property has climbed 1 band since. Between certificates, lighting went from Very Poor to Very Good; while roof efficiency dropped from Good to Average.
It hasn't traded since March 1996, a hold of 30 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 £149,000 sits 189.3% above the 1996 sale of £51,500. On a £-per-square-foot basis, the last sale (£84/sq ft) was about 54.4% below the postcode norm.

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 99a is modelled from its 57 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 99a. 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 99a was lodged in March 2021 at band C and is valid until March 2031. 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 99a. 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.
- Council tax band
- 99a is in council tax band A. 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.
