About 11 Janson Road
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
11 Janson Road is a three-bedroom semi-detached house in Southampton (SO15 5FU). It has a recorded floor area of 136 m² (around 1459 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (July 2010) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump. The latest certificate is from July 2010, so improvements made since then won't be reflected.
Held since October 2010 — that's 16 years off the open market, well above the local norm. Across 1996–2010, sale prices on this property compounded at 11.5% per year. Today's modelled estimate of £380,000 sits 53.2% above the 2010 sale of £248,000. One planning record on file: an extension approved in 2011. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).

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 11 Janson Road is modelled from its 136 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in SO15 5FU. 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. 3 sales are recorded for 11 Janson Road. 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 11 Janson Road was lodged in July 2010 at band E and expired in July 2020, 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. 1 application is matched to 11 Janson Road. 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 18 months, which places each incident at an approximate point. The 31 schools and 30 stops listed are measured in a straight line from SO15 5FU, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 11 Janson Road is in council tax band D. 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.
