About 12 Clarendon Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
12 Clarendon Street is a semi-detached house in Portsmouth (PO1 4JA). It has a recorded floor area of 89 m² (around 958 sq ft), construction records dating it to 1950-1966 and council tax band A. The latest certificate (August 2015) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.

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 12 Clarendon Street is modelled from its 89 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in PO1 4JA. 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 12 Clarendon Street. 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 12 Clarendon Street was lodged in August 2015 at band E and expired in August 2025, 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 12 Clarendon Street. 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 43 schools and 30 stops listed are measured in a straight line from PO1 4JA, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 12 Clarendon Street 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.
