Harmers Wood is currently both a Charity under the auspices of the Charity Commission and a Company registered at Companies House. This limits liability of the Trustees to the assets of the Company only.
The current document is about 14 pages long and probably needs to be simplified for everyday use, but changes have to be approved by the Charity Commission.
The limited Company aspect of the governance of Harmers Wood refers to Directors and a Company Secretary while the Charity Commission refers to Trustees.
The first page of the constitution states that:
The Friends of Harmers Wood Trust is a Charitable Company Limited by Guarantee run by a board of Directors and Trustees. It goes on to say that one person may be appointed both to the board and elected as an officer to the Trust.
