Maintenance grants
The National Churches Trust’s Foundation Grant Programme for urgent maintenance works and small repairs offers small grants between £500 and £5,000. The final deadline for applications in 2022 will be the end of October. Please encourage churches in your networks to apply as soon as possible to improve their chances of accessing the funds. Project costs should not exceed £10,000 excl. VAT, and awards will not exceed 50% of the costs. Items should be identified as high priority within a recent Quinquennial Inspection or Survey Report. Small roof and masonry repairs are often funded through the programme. Further information and a link to the online application form can be found here. https://www.nationalchurchestrust.org/get-support/grants/foundation-maintenance
