10 Clos Ty Mawr is a detached house in Penllergaer, Swansea, Swansea (SA4 9DA). It has a recorded floor area of 152 m² (around 1636 sq ft), construction records dating it to 1967-1975 and council tax band F.

Between certificates, lighting went from Good to Very Good; while wall efficiency dropped from Good to Poor. The recommended improvements would lift it to B (score 81), a 3-band jump.

Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 10 Clos Ty Mawr is modelled from its 152 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SA4 9DA. 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. No sale is recorded for 10 Clos Ty Mawr, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 10 Clos Ty Mawr was lodged in October 2013 at band E and expired in October 2023, so a new one is needed to sell or let. 3 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 10 Clos Ty Mawr. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.

- 10 Clos Ty Mawr is in council tax band F. 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.
