Overview

About 23 Garth Olwg

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

23 Garth Olwg is a three-bedroom end-of-terrace house in Gwaelod-Y-Garth, Cardiff, Cardiff (CF15 9HW). It has a recorded floor area of 157 m² (around 1690 sq ft), construction records dating it to 1950-1966 and council tax band E. The latest certificate (March 2013) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from March 2013, so improvements made since then won't be reflected.

At 157 m² the property is well over the postcode median (81 m² across 18 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Across 1997–2013, sale prices on this property compounded at 8.7% per year. Today's modelled estimate of £362,000 sits 57.4% above the 2013 sale of £230,000. On a £-per-square-foot basis, the last sale (£136/sq ft) was about 33.2% below the postcode norm. Last sold in November 2013, so it's been off the market for around 13 years.

Valuation method in detail
How the estimate is made
The estimate for 23 Garth Olwg is modelled from its 157 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF15 9HW. 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 23 Garth Olwg. 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 23 Garth Olwg was lodged in March 2013 at band E and expired in March 2023, 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 23 Garth Olwg. 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. Schools and stops are measured in a straight line from CF15 9HW.
Council tax band
23 Garth Olwg 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.
