I’ve been having a look to see what the situation is with nail cutting UK wide, but I can only find NHS podiatry services offering a nail cutting service to people who have an underlying pathology, eg diabetes, which affects the circulation to your feet - this appears to be nationwide.
Most areas seem to have arrangements for agencies such as Age UK to do toenail cutting, but it’s not available during the pandemic due to the risk to volunteers of contracting COVID. Not much help I’m afraid Anniebach, the only thing I can think of is to ring your GP practice to see if the district nurses would come in to do it for you as it’s affecting your mobility?
There must be thousands of people across the UK with this problem - I know my my mum who’s in the East Midlands is paying a private chiropodist to come to do hers, the chiropodist travels but does a number of people in the village on the same day, I think she got the lady’s number from her local volunteer bureau.
