Overview

About 20 Cork House

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

20 Cork House is a two-bedroom mid-terrace house in Maritime Quarter, Swansea, Swansea (SA1 1RT). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1996-2002 and council tax band E. At 63 m² this is the 21st smallest of 41 units on EPC record in the building, where floor areas span 39–120 m². The building's EPC ratings span E to B across 41 units on file. Other recorded features include notable views. The latest certificate (May 2016) shows a C (score 78), near the top of the C band. The recommended improvements would push it to B (score 87). Main heating runs on electricity. The latest certificate is from May 2016, so improvements made since then won't be reflected.

Untraded for 26 years, with the last transfer in February 2000. 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 £165,000 sits 100.6% above the 2000 sale of £82,250. On a £-per-square-foot basis, the last sale (£121/sq ft) was about 32.3% below the postcode norm.

Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 20 Cork House is modelled from its 63 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 1RT. 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 20 Cork 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 20 Cork House was lodged in May 2016 at band C and expired in May 2026, 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 20 Cork 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 16 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA1 1RT.
Council tax band
20 Cork House is in council tax band E. 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.
