The Castle Hotel Windsor

What The Castle Hotel Windsor does

The Castle Hotel Windsor is a 108-room boutique heritage hotel located at 18 High Street, Windsor, directly opposite Windsor Castle, and operated as part of the Sutton Hotel Collection (Sir Richard Sutton Limited). Founded in 1528 as the Mermaid Inn, it is among the oldest inns in Windsor, with eight historical innkeepers having held Royal Warrants. The property comprises a Main House and Mews Building (the former royal stables) offering room categories from Snug rooms to Royal Warrant Suites, supported by 10 flexible meeting rooms including the largest ballroom in central Windsor (up to 400 delegates). Revenue streams include room bookings (via HotelRez and direct website with a 12% direct discount), food and beverage (Penningtons British Brasserie & Bar launching August 2026 in partnership with Auden Hospitality), meetings and events (corporate conferences, weddings up to 260 guests), and gift voucher and festive packages priced £1,540-£2,100.

The business is currently mid-transformation: a £9.5 million refurbishment covering all 108 bedrooms, public areas, and the new brasserie is being executed by interior designer 3DReid, with relaunch scheduled for summer 2026 as part of a wider £38M+ three-year investment across the Sutton Hotel Collection portfolio. Technology infrastructure comprises HotelRez booking, SevenRooms restaurant reservations, Barco ClickShare wireless presentation in flagship meeting rooms, Theatro360 virtual tours across nine event spaces, Chromecast-enabled smart TVs, and Greenview sustainability measurement. The hotel holds Gold Green Tourism and Gold Green Meetings Awards, and has been twice named in Caterer's Top 30 Best Places to Work in Hospitality.

Commercial channels emphasise direct-to-consumer booking with a 12% discount code (DIRECT), corporate and wedding enquiry funnels, email newsletter, PR via Sauce Communications, and seasonal package campaigns (Summer Edit up to 25% off, Festive Breaks, Dog-Friendly Breaks). Distribution also extends to OTA platforms via HotelRez chain code 29258. Primary customer segments are leisure tourists, corporate meetings and events (including M4 corridor technology and healthcare companies), and wedding parties, with secondary demand from pet-friendly travellers and corporate Christmas celebrations. The parent Sir Richard Sutton Limited is a diversified private group covering hospitality, property, and farming.
