Overview

About 21 Cork House

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

21 Cork House is a two-bedroom mid-terrace house in Maritime Quarter, Swansea, Swansea (SA1 1RT). It has a recorded floor area of 68 m² (around 732 sq ft), construction records dating it to 1983-1990 and council tax band E. The latest certificate (February 2023) shows a D (score 68), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since March 2013. Between certificates, hot-water efficiency went from Very Poor to Average, lighting went from Very Poor to Very Good and main heating went from Poor to Average. The recommended improvements would push it to C (score 72). Main heating runs on electricity. At 68 m² this is the 28th 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 a balcony and notable views.

Across 2000–2004, sale prices on this property compounded at 24.5% per year. Today's modelled estimate of £192,000 is 18.3% below the 2004 sale of £235,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£321/sq ft) was about 80.3% above the typical sold price in the postcode. It hasn't traded since November 2004, a hold of 22 years that's notably long for the area. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs).

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 21 Cork House. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
