The work is heritage building conservation and refurbishment (CPV 45453100), focused on preserving and renewing this internationally significant structure. Royal Botanic Gardens, Kew is the buying organisation. The location is Kew, Richmond, in the London area. This is a single planned package rather than a set of separately described workstreams, and its stated purpose is to conserve and renew the Palm House as a whole. The project concerns a landmark historic glasshouse, so its scope is specialist conservation and renewal rather than routine building maintenance. The process is at planning: Kew has stated its intention to procure but has not issued an invitation to tender. The buyer plans to use market engagement, with a Market Engagement Questionnaire and the possibility of follow-up site visits, clarification discussions and confidential, non-binding meetings at its discretion. Responses to the questionnaire are expected by 26 October 2026; this is an engagement date, not a tender deadline. The estimated value is £25 million excluding VAT (£30 million including VAT). The planned contract period runs from 14 April 2027 to 18 April 2029. It is one lot. No award criteria or evaluation basis has yet been set out. This project is likely to suit contractors with the specialist capability to conserve and renew major heritage buildings, particularly listed structures and historic glasshouses. Suppliers should consider whether they can manage work on an internationally significant asset within a UNESCO World Heritage Site and deliver a comprehensive conservation package, rather than a narrow refurbishment task. The scale and setting are likely to favour businesses with relevant heritage conservation experience, suitable technical teams and the capacity to coordinate a substantial, multi-year works project. The planned market engagement gives interested suppliers a chance to provide input through a questionnaire and potentially take part in further discussions or a site visit. No specific accreditation, minimum experience threshold or other qualification requirement has been stated at this planning stage. ## Notice The Palm House is a Grade I listed structure situated within the UNESCO World Heritage Site at Royal Botanic Gardens, Kew and is widely recognised as one of the most significant surviving Victorian glasshouses in the world. The project will involve the comprehensive conservation and renewal of this internationally important heritage asset.
