How the estimate is made

The estimate for 21 Martin Street is modelled from its 80 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA6 5DD. 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.

Overview

About 21 Martin Street

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

21 Martin Street is a two-bedroom end-of-terrace house in Clydach, Swansea, Swansea (SA6 5DD). It has a recorded floor area of 80 m² (around 861 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (June 2015) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 86), a 3-band jump. The latest certificate is from June 2015, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.

5 planning records sit against the property, 2 approved, 2 refused. Past consents include an extension and a garage conversion, meaningful when judging how the property has evolved. At 80 m² it's 19.2% smaller than the typical home in the postcode (99 m² median across 7 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Across 2009–2015, sale prices on this property compounded at 2.9% per year. Today's modelled estimate of £158,000 is 39.8% above the 2015 sale price. On a £-per-square-foot basis, the last sale (£131/sq ft) was about 35.6% above the typical sold price in the postcode. On the market in March 2015 and unlisted since — roughly 11 years.

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 21 Martin Street is modelled from its 80 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA6 5DD. 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 21 Martin 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 21 Martin Street was lodged in June 2015 at band E and expired in June 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. 5 applications are matched to 21 Martin 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 14 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA6 5DD.
Council tax band
21 Martin Street is in council tax band B. 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.
