Summary of the contracting process

The City of London, formally the Mayor and Commonalty and Citizens of the City of London, procured consultancy services for Mansion House covering air source heat pumps and photovoltaic panels. The work is construction consultancy, classified under CPV 71530000, and is delivered in London. The requirement is a specialist advisory commission supporting the assessment, development or delivery of renewable heating and solar photovoltaic measures at Mansion House. It is a services contract and was identified as suitable for small and medium-sized enterprises. The buyer is a public authority based at Guildhall, London, and the appointed supplier is Baily Garner LLP.

The procurement is complete and was awarded to Baily Garner LLP on 10 July 2026. The awarded contract value is £66,841.25. The contract period runs from 10 July 2026 to 30 November 2026. The contract was awarded by direct award through the Multi-Disciplinary Consultancy Lot of the South East Consortium Asset & Development Consultancy Framework, using a selective procurement route and a framework call-off. The tender submission deadline was 26 June 2026 at 12:00. The procurement was not divided into lots. The published outcome records Baily Garner LLP as the active award recipient for the full requirement.

This award is relevant to multidisciplinary construction and building-services consultancies able to advise public-sector clients on air source heat pump and photovoltaic panel projects. A credible competitor for a future requirement would need practical expertise in renewable heating, solar generation and the integration of these technologies into an existing heritage or civic building. Relevant capability may include feasibility and options appraisal, technical design advice, building assessment, cost and programme input, procurement support and coordination with other property professionals. The route also shows the value of being an approved supplier on the South East Consortium Asset & Development Consultancy Framework, while the stated SME suitability indicates that smaller specialist consultancies may be able to compete when similar work returns.
