About us
The Castle Hotel, centrally located in the heart of Windsor is a prestigious setting for meetings, conferences and networking events. The self-contained conference centre offers 10 versatile meeting rooms suitable for 4 to 400 delegates with a dedicated breakout area and multiple breakout room available. The grand Windsor Suite, the largest ballroom in Windsor can accommodate up to 400 guests in theatre style and 300 in banquet style. The suite is equipped with ClickShare Present wireless technology for seamless presenting. Holders of the Green Meetings Gold Award and the Gold Green Tourism Award, the hotel has a strong commitment to sustainability across all areas of the business and offers a dedicated green meetings package. From November 2025, The Castle Hotel Windsor will undergo a £9.5 million refurbishment, to be completed in 2026. The multi-phase transformation led by interior designers including 3DReid will start in November 2025 and see a full refresh of all bedrooms and suites across the hotel. Starting with the Mews and bedrooms in the original hotel, and concluding with the Park Wing, the refresh will also involve a redesign of the ground floor and the launch of a new British brasserie concept in the restaurant. A significant aspect of the investment includes the team which will be increased and developed to deliver an enhanced guest service. Completion of this significant refurbishment is scheduled for end 2026. The conference centre will be unaffected during this time. The hotel has excellent transport links, close to junction 6 of the M4, less than 10 miles from Heathrow Airport and 800m from Windsor & Eton Central train station. Central London Paddington or London Waterloo is less than an hour. The hotel also benefits from 100 onsite car parking spaces including EV charging points. The parking spaces will be limited during our refurbishment. Please let us know your requirements in advance.
