Although this pub is not a listed building, it is on the Campaign for Real Ale’s (CAMRA) Local Inventory as having an interior of Local Historic Interest, and the description is as follows: "1930s (probably 1934 according to locals) ex-Charrington pub still with three rooms. There are three Toby Jug/House of Toby panels on exterior walls.

The panelled bar counters in all three rooms look original, are canted and dark painted. The front room has parquet floor and the fielded panelling on the walls has longer vertical panels than the other rooms, but does looks original. The canted panelled bar counter looks original and is dark painted with a red and white ‘piano’ tiled apron with black trim around the base. –The bar back has some old parts but is mostly new work. There is a tiled and wood surround art deco style fireplace looks 1930s.

A doorway leads to a room on the left. Fielded panelling to two-thirds height here is painted grey, is of a different design to that in the rear room, and looks like a modern addition as a fireplace on the left has either been removed or concealed behind it The canted panelled bar counter looks original and is dark painted.

An enlarged opening created about 10 years ago (again according to locals) leads to the room at the rear, which has original panelling with indentations on the horizontal bars, sadly most is painted gastro-grey-blue Good 1930s brick fireplace, with slim red tiles/brickwork in an attractive fan effect design. The canted panelled bar counter looks original and is dark painted. Bar back is a mixture of old and new.

Behind the servery and to the right is a semi-circular screened area, now containing a kitchen. On the right hand side of building is a door that used to lead to an off sales, but now leads to the kitchen. A function room in the basement contains what appears to be an original brick built fireplace, but everything else in here (bar counter, wood covering on the pillars) are modern fake reproductions."
