The parochial church council at St George's in Stamford needs more than £14,000 to restore the church's four bells and have them work in a single chime, and to repair the tower.
The church is also planning to transform an unused part of the building into two toilets and a kitchen by autumn next year as part of a project costing more than £150,000.
Last week it received £3,000 from the Harry Skells Trust in Stamford to go towards the costs of reinstating the bells and will be approaching parishoners for help in the fundraising.
The church has received permission for the kitchen and toilets by Diocesan Advisory Committee, an ecclestical planning committee, but this is subject to a 28-day public consultation.
The Rector, the Rev Martyn Taylor, said the work would bring the building in line with disabled access legislation.
He said: "It will make the building much more user-friendly. We have been hoping to do it for a long time and we are looking forward to seeing it come to fruition."
Elderly people and children have problems accessing the church's current toilet in the chancel and members rely on an urn to provide refreshments after services.
The plans focus on space either side of the tower where two toilets and a basic kitchen could be installed behind oak screening.
The council will be seeking tenders for the project once planning permission has been confirmed and parishoners have until Friday, October 17, to comment.
The Rev Taylor said this project would be a continuation of the building work undertaken in the mid-1990s when a dias was added.
Steel joists are needed to shore up the tower's timber frame which is becoming too old to support the bells and hopefully this work will be done before the end of the year.
A series of grant applications have been submitted to retune and reinstate the four bells, which include one dating back to 1697 made by the Tobie Norris foundry in Stamford.
Work is currently going on at the site to renovate the stained glass windows along with repairs to the roof.
