LORD Hunt of Wirral has sent out thousands of letters asking residents to help him secure the future of Hoylake Cottage Hospital.
David Hunt has written to 18,000 households and businesses for donations towards the multi-million pound redevelopment scheme vital for the hospital's survival.
The project to update its facilities is expected to cost up to £4m and a major fundraising drive is under way.
Lord Hunt said: "We need the community's support for this.
"The hospital belongs to local people and it is very important they support what we are doing.
"New government regulations meant we needed to expand and improve the hospital if it was to survive and we have to fight to keep it.
"We think local people will want to help what is a fantastic institution that has made us the envy of many parts of the UK.
"They have been extremely generous in the past and I wanted to write to them directly to ask for their support."
Following an outcry from residents, the initial design for a new hospital building was withdrawn.
They had been angry that the old 105-year-old hospital was to be torn down.
Now the present building is to be retained and a new 60-bed nursing unit added.
Lord Hunt said: "There were always concerns from people about what we were going to do, but I think they have now been reassured that this really is the only way forward."
The Charitable Trust that runs it put forward £1m towards the revamp.
Trustees plan to borrow up to £2m, and it is hoped a £1m shortfall can be made up from local contributions. For an appeal pack, contact Christine Redmond on 632 7306.
