Overview

About 21 Sanderling Drive

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

21 Sanderling Drive is a four-bedroom detached house in St. Mellons, Cardiff, Cardiff (CF3 0DA). It has a recorded floor area of 124 m² (around 1335 sq ft), construction records dating it to 1983-1990 and council tax band E. The latest certificate (June 2016) returns a B (score 83), comfortably above the UK average. When first surveyed in October 2015 the rating was D, the property has climbed 2 bands since. Between certificates, roof efficiency went from Average to Good and lighting went from Good to Very Good. The latest certificate is from June 2016, so improvements made since then won't be reflected. Other recorded features include a conservatory and a loft.

At 124 m² it's 28.9% larger than the typical home in the postcode (96 m² median across 13 EPCs). On energy efficiency it sits in the top 10% of properties in this postcode.

Valuation method in detail
How the estimate is made
The estimate for 21 Sanderling Drive is modelled from its 124 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF3 0DA. 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 Sanderling Drive. 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 Sanderling Drive was lodged in June 2016 at band B and expired in June 2026, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 Sanderling Drive. 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 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 0DA.
Council tax band
21 Sanderling Drive 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.
