About 1 Blenheim House
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
1 Blenheim House is an end-of-terrace house in Portsmouth (PO1 3GR). It has a recorded floor area of 37 m² (around 398 sq ft), construction records dating it to 2003-2006 and council tax band A. At 37 m² this is the 2nd smallest of 3 units on EPC record in the building, where floor areas span 34–63 m². The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (59 versus a best of 76). The latest certificate (October 2020) shows a D (score 59), a step below the typical UK home. Earlier certificates rated it C (January 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 78). Main heating runs on electricity.
Untraded for 17 years, with the last transfer in April 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £114,000 is 42.5% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£201/sq ft) was about 19.9% below the postcode norm.

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 1 Blenheim House is modelled from its 37 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in PO1 3GR. 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 1 Blenheim 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 1 Blenheim House was lodged in October 2020 at band D and is valid until October 2030. 3 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 1 Blenheim 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 33 schools and 30 stops listed are measured in a straight line from PO1 3GR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 1 Blenheim House 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.
