10-11 Carlton House Terrace, home of The British Academy for the humanities and social sciences, has launched an open tender for new accredited meetings and event services suppliers as it looks to strengthen its network of specialist partners.
Located in Westminster, London, the Grade I listed Georgian venue hosts more than 500 events each year, welcoming between 10 and 400 guests. With ten versatile event spaces, the venue accommodates a wide range of occasions, including conferences, seminars, product launches, weddings, fashion shows and film shoots.
10-11 Carlton House Terrace Opens Supplier Tender
The new 10-11 Carlton House Terrace supplier tender is designed to create a fresh network of event professionals capable of supporting the venue’s diverse and international client base.
The venue is inviting applications from suppliers across multiple event service categories. The initiative aims to identify partners who can deliver high-quality services while understanding the operational requirements of working within a historic Grade I listed building.
The tender represents the venue’s first major supplier search since 2023 and reflects changes in expectations around sustainability, creativity, technology and equity, diversity and inclusion.
Accredited and Recommended Supplier Categories
The supplier programme has been divided into two main categories: accredited suppliers and recommended suppliers.
Accredited suppliers will include florists and production companies. Applicants in these categories will complete a two-stage assessment process consisting of a written submission followed by an interview.
The recommended supplier categories cover a broader range of event services. These include entertainment, photography, videography, cakes, event planners, stylists, furniture, décor and accessibility services.
Accessibility services being considered include subtitling, sign language, translation, crèche provision and live audio description. Suppliers in these categories will be assessed through written submissions.
Three-Year Supplier Contracts
10-11 Carlton House Terrace aims to appoint between four and eight suppliers in each category. Successful applicants will receive a three-year contract, creating an opportunity for selected businesses to become long-term partners of the prestigious Westminster venue.
Experience working within listed buildings will be an important consideration during the selection process. The venue is also looking for suppliers with a strong marketing presence and the ability to demonstrate professional expertise relevant to its varied events programme.
Sustainability and EDI at the Centre of Tender
Sustainability and equity, diversity and inclusion (EDI) will be key requirements throughout the tender process.
The venue is seeking suppliers that can demonstrate an exemplary commitment to responsible business practices and inclusive event delivery. These requirements reflect the strategic priorities of both 10-11 Carlton House Terrace and The British Academy.
For event suppliers, the tender provides an opportunity to demonstrate not only their creative and operational capabilities but also their approach to sustainability, accessibility and inclusive experiences.
Open House Sessions for Interested Suppliers
Ahead of the application deadline, 10-11 Carlton House Terrace will host a series of Open House sessions for prospective suppliers.
The sessions will allow interested businesses to tour the venue, understand its spaces and ask questions about the tender and application process.
The scheduled Open House sessions are:
Wednesday 5 August 2026: 9:30am–12pm
Wednesday 12 August 2026: 1pm–5pm
Wednesday 19 August 2026: 9:30am–12pm

Venue Expands Event and Hybrid Capabilities
The latest tender follows significant developments at 10-11 Carlton House Terrace. Since the previous supplier tender in 2023, the venue has opened three technically advanced lower-ground-floor spaces.
The additional spaces have expanded the venue’s capabilities for hybrid, livestreamed and virtual events, increasing the range of event formats that can be delivered at the Westminster location.
The venue says this expansion has also increased the need for specialist suppliers capable of supporting technically sophisticated events while maintaining the operational standards required within a Grade I listed property.
Catherine Owen Highlights New Supplier Requirements
Catherine Owen, Head of Venue Sales & Marketing at 10-11 Carlton House Terrace, said expectations around sustainability, EDI and creativity have changed significantly since the venue’s previous tender in 2023.
She highlighted the importance of specialist expertise when working within a Grade I listed building and said the venue is looking for a broad range of service partners with strong sustainability and EDI credentials.
According to Owen, the new supplier cohort will play an important role in maintaining the delivery standards associated with events at 10-11 Carlton House Terrace.
