Who owns the Millstream Hotel & Sea School Restaurant

History of the Millstream Hotel

The Millstream Hotel is a redbrick country house set in the historic village of Bosham. Its official site describes the Sea School Restaurant as a venue where “Head Chef Neil and his team create the dinner menu,” but public records do not name the current ownership structure. The hotel appears to be privately operated; no parent company or individual owner is listed on the website or in the business directory listings we reviewed.

Current ownership details

Ownership specifics are not disclosed on the hotel’s own channels. A search of Companies House (the UK business register) did not return a distinct registered company for the property under the “Millstream Hotel” name, suggesting it may be held under a separate entity or by a private individual who does not trade under the hotel’s name. Readers seeking ownership details should contact the hotel directly.

The bottom line: The identity of the owners is not publicly advertised. The hotel’s management team, led by an unnamed general manager and Head Chef Neil, is the public face of the operation.

The Millstream Hotel & Sea School Restaurant menu

Sample menu items

The official official restaurant description states that “the following are sample menus and are subject to change due to seasonality.” Head Chef Neil and his team produce a dinner menu that “reflects seasonal produce with a selection of new dishes on the menu as well as some guest favourites”. Cuisine is described on Tripadvisor as European and British, with meat, poultry, game, fish, and vegetarian options alongside traditional desserts.

Price range indication

Starter prices visible on Tripadvisor’s menu excerpts range from £10.50 for smoked haddock chowder to £17.50 for Scottish scallops. A twice‑baked blue cheese soufflé also appears at the higher end. Main‑course pricing is not consistently listed across the sources we examined. The Sunday lunch is priced at £35 for three courses and £30 for two courses, based on the October 2024 PDF menu.

Sunday lunch menu

The official PDF confirms a three‑course Sunday lunch at £35 and a two‑course option at £30. The hotel’s site notes that this is a sample menu and may change seasonally. Diners should check the latest offering when booking.

Why this matters: The Sea School Restaurant positions itself as a premium seasonal dining destination. The limited dinner window (6‑8:30 PM) and the variable menu mean that advance menu confirmation is advisable before making a special trip.

The pattern: The restaurant’s reputation is built on menu variety and seasonal freshness, but its early closing time (8:30 PM) may be a drawback for those who prefer later dining.
