How to read this page

Valuation method in detail
How the estimate is made
The estimate for 12 Seaview Avenue is modelled from its 111 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in PO16 8JB. 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 Seaview Avenue. 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 Seaview Avenue was lodged in August 2015 at band B 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 Seaview Avenue. 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 13 months, which places each incident at an approximate point. The 11 schools and 30 stops listed are measured in a straight line from PO16 8JB, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
