Cadw lists buildings of special architectural or historic interest in three grades: Grade I for buildings of exceptional interest, Grade II* for particularly important buildings of more than special interest, and Grade II for buildings of special interest. Listing protects the whole building, inside and out.

Every entry on Cadw’s register of listed buildings whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings.

Two measures, each ranked against every UK town of 1,000 or more, with protected heritage counting twice as much as the age of homes. Protected heritage counts each listed building by its grade (Grade I three points, II* two, II one), each scheduled monument and battlefield two, and each registered park or garden by its grade; it is ranked both per 10,000 residents and as a total, so a village with one fine church doesn’t outrank a historic city. The second measure is the share of homes built before 1919, from the Valuation Office Agency’s council tax records. History is a character grade: it describes the town and isn’t part of the overall grade.

83% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was 1900–18, which added 4.4% of today’s homes.

Valuation Office Agency, council tax stock of properties by build period, 31 March 2025, for the neighbourhoods (LSOAs) that make up the town, split by where their residents live. Homes with no recorded build period (0 here) are left out; 1939–44 is not a period in the data.

Old houses are part of New Tredegar’s character: 87% of its homes were built before 1919, against 15% in the typical UK town. All told, the list holds 4 listed buildings, including Elliot Colliery Winding Engine House and Engine. For its size the list is short: per resident, it has more listed heritage than only 24% of UK towns. Otherwise the figures are ordinary: like most towns its size, it has no Grade I building; and all its entries went on the list in 2001.
