13 listed buildings, 1 of them Grade II*

Historic England lists buildings in three grades: Grade I for buildings of exceptional interest (about 2.5% of all listed buildings), Grade II* for particularly important buildings of more than special interest (about 5.8%), and Grade II for buildings of special interest (about 91.7%). Listing protects the whole building, inside and out.

Every entry on the National Heritage List for England whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings.

Historic England’s conservation areas layer, supplied by councils (incomplete in places, so a page fact, never graded). Hectares are the part of each area inside the built-up area.

The first 13 entries were listed in 1984. Only 0 have been added in the last 15 years.

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.

Challock has 13 listed buildings. A conservation area protects part of it. More than half went on the list in a single year, 1984: 13 of 13. Otherwise the figures are ordinary: like most towns its size, it has no Grade I building; per resident it sits near the middle of UK towns; and 15% of its homes were built before 1919, close to the 15% in the typical UK town.
