Overview

About 12 Brunswick Street

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

12 Brunswick Street is a three-bedroom mid-terrace house in Swansea (SA1 4JR). It has a recorded floor area of 97 m² (around 1042 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (January 2009) shows an F (score 32), near the bottom of the EPC scale. The recommended improvements would push it to E (score 49). The latest certificate is from January 2009, so improvements made since then won't be reflected.

It hasn't traded since August 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 97 m² it's 21.9% smaller than the typical home in the postcode (124 m² median across 21 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £170,000 is 30.8% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£125/sq ft) was about 92.2% above the typical sold price in the postcode.

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 12 Brunswick Street is modelled from its 97 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 4JR. 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 12 Brunswick Street. 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 Brunswick Street was lodged in January 2009 at band F and expired in January 2019, 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 Brunswick Street. 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 4JR.
Council tax band
12 Brunswick Street is in council tax band C. 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.
