In 1987 contributions of £30k from Stroud Council and £24k from English Heritage were made for emergency repairs to prevent the Mansion from falling into dereliction. The conservation programme has been in progress since the early 1990’s. Major projects and grant aid for conservation include:
- 1995-2005 Heritage Lottery Fund – rainwater system, grand stair and NW wing (£821k)
- 1999 Paul Getty Trust – drawing room internal refurbishment (£10k)
- 2009 Country Houses Foundation – N range roof (£50k)
- 2010 Heritage Lottery Fund – Interpretation (£50k)
- 2017-18 David Thomas Foundation – Improvements to chapel (£10k)
- 2019-20 Historic England – Conservation Management Plan, Emergency repairs to Brewery Gable and Feasibility Study on repairs to Ironing room roof.
- 2020-21 Historic England and the Historic Houses Foundation – repairs to ironing room roof, part of the north range roof, chimneys 7 and 8, and two windows on the east front (£470k)
- 2021 Historic England £76k for repair of chimney 6
- 2022 Historic England and the Historic Houses Foundation – repairs to the north slope of the south range roof, towards the east end of the building (220k)
In 2015 the repair costs were completely revised. These have been updated to current values and are shown above.
At least £5m is needed to return the Mansion to the 1873 condition.
The Mansion chapel is on Historic England’s Buildings at Risk register.
