Overview

About 23 Dulwich Gardens

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

23 Dulwich Gardens is a two-bedroom semi-detached house in Cardiff (CF5 1SE). It has a recorded floor area of 36 m² (around 388 sq ft), construction records dating it to 1967-1975 and council tax band C. At 36 m² this is the smallest unit on EPC record across the building (36–183 m²). The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (July 2017) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 74).

Today's modelled estimate of £156,000 sits 56% above the 2017 sale of £100,000. On a £-per-square-foot basis, the last sale (£258/sq ft) was about 17.7% above the typical sold price in the postcode. At 36 m² it sits well below the postcode median (69 m² across 16 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs). Last sold in December 2017, so it's been off the market for around 9 years.

Valuation method in detail
How the estimate is made
The estimate for 23 Dulwich Gardens is modelled from its 36 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF5 1SE. 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 23 Dulwich Gardens. 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 Dulwich Gardens was lodged in July 2017 at band D and is valid until July 2027. 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 Dulwich Gardens. 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 CF5 1SE.
Council tax band
23 Dulwich Gardens 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.
