Southwark Council have a commemorative donations policy which can be viewed here
The image above shows the Victorian style of bench now being used. Unfortunately the Council is not installing any new Memorial Benches at present, unless it is to replace an old bench that is beyond repair, or a new location is identified that requires a bench. This is a Borough-wide policy. In the meantime, your details can be added to a database so you can be contacted if a position becomes available. Please contact Will Walpole, Dulwich Park Manager, Francis Peek Centre, for further information.
Southwark Council will accept donations for trees, plants or shrubs but no memorial plaque can be installed and the species and location need to be agreed by Council Officers. Your donation will be displayed in a ‘Memorial book’ at the Francis Peek Centre. Again, please contact Will Walpole for more information.
