What Cliveden Conservation does

Cliveden Conservation Workshop Ltd. is a privately-held, family-owned UK heritage conservation practice founded in 1988 by Trevor Proudfoot and headquartered at the Cliveden Estate in Taplow, Berkshire. The firm specialises in the conservation of statuary, masonry, terracotta, mosaics, decorative plasterwork, and wall paintings, delivered through three regional workshops covering Berkshire, Somerset (Bath), and the East of England (Stowmarket, Suffolk). Its core services span stonework cleaning and repair, plaster stabilisation, decorative-arts conservation led by ICON-accredited practitioners, and advisory services backed by in-house laboratory material analysis. A complementary Winter Covers product line protects outdoor sculpture from weather damage, and a Heritage Skills & Training offering delivers apprenticeships in partnership with the King's Foundation.

Cliveden Conservation operates a project-based professional-services model, secured through competitive tendering and direct appointments with heritage asset owners. Its customer base is concentrated in UK heritage institutions — principally the National Trust, Church of England and Roman Catholic cathedrals (Wells, Bristol, Nottingham, St Albans), English Heritage, Historic England, museums (Dorset, Burrell Collection, Salisbury), universities (Christ Church Oxford), and local authorities (Reading Borough Council). Many engagements are large, multi-year and funded by the National Lottery Heritage Fund, Historic England grants, or institutional capital budgets. Notable projects include the Cybele and Juno statue recreation at Stowe, the Pugin decorative scheme restoration at Nottingham Cathedral, the Seafarers' Chapel floor at Bristol Cathedral, and a 2000-year-old mosaic move at Dorset Museum.

The business is differentiated by a talent moat of accredited and award-winning conservators (SPAB Master Craftsman, Stone Federation Natural Stone Awards, Duke of Gloucester Award, ICON accreditation), 35+ years of portfolio depth, and earned-media visibility through BBC Two's 'Hidden Treasures of the National Trust'. Go-to-market is enterprise field sales into a small number of heritage-sector procurers, with PR, industry exhibitions (Museums + Heritage Show), and training partnerships (Stone Federation, WREN300, King's Foundation) supporting brand awareness and pipeline. The company employs between 11 and 50 staff across its three sites, remains independently owned by the Proudfoot family, and does not use external capital or operate outside the United Kingdom.

Direct peers

• The Morton Partnership: Consulting structural and conservation engineers specialising in historic buildings, cathedrals and monuments. Comparable in heritage-sector focus and advisory/material analysis scope, often engaged alongside or in competition with Cliveden on complex projects.
• Stonewest: UK specialist stone masonry and conservation contractor working on cathedrals, monuments and historic estates. Closest direct comparable to Cliveden's stonework practice in scale, craft focus and client base (churches, heritage trusts, local authorities).
• Cathedral Works Organisation (CWO): Charity-affiliated conservation contractor dedicated to cathedral and church fabric, including stone, plaster and decorative arts. Direct peer for Cliveden's cathedral portfolio (Wells, Bristol, St Albans, Nottingham) and a competitor in tender processes.
• Skillington Workshops: Specialist heritage stonemasonry and conservation workshop delivering repair and replication work for churches, cathedrals and historic buildings. Directly comparable in craft specialism, traditional 'like-for-like' approach and ecclesiastical client base.
• Wessex Conservation Services: Heritage conservation contractor covering stone, plaster and decorative works across the south of England. Direct competitor for cathedral, National Trust and council tenders where Cliveden also bids.

Broad incumbents

• Donald Insall Associates: Long-established heritage architecture and conservation consultancy with a much larger practice. Competes for advisory, planning and project-lead roles on the same cathedrals, National Trust and listed-building briefs that Cliveden services on the conservation execution side.
• Purcell: Major UK architecture practice with a dedicated heritage and conservation team. Acts as lead designer on many of the cathedral and historic estate projects where Cliveden is contractor, making it both a partner and competitor in the heritage ecosystem.
• Historic England (in-house conservation team): Public body that both funds/regulates and directly delivers heritage-at-risk conservation works. Competes for and commissions projects in Cliveden's niche, and shapes the funding environment for the firm's cathedral and National Trust work.
