This is a consequence of the way in which the CofE is financially liable for the maintenance of its historic buildings, which are nothing but money pits. A few years ago they realised that they could use old charges in order to fund repairs that hey couldn’t otherwise meet. That they couldn’t foresee the consequences to individuals, communities and the damage to their reputation just indicates how wedded to these buildings above people some of the parochial church councils are.
It’s possible to get round it by taking out an inexpensive chancel repair liability insurance policy, provided it’s done before any charge is asked for. I believe that church policy has changed a lot on this anyway because they realised that it was hurting people.
The alternative to expecting the CofE to repair and maintain buildings for which it doesn’t have the money (each parish is responsible for its own buildings, there isn’t a central pot) is for all listed churches to be brought into state ownership. The bulk of the repair and maintenance costs will be met by taxpayers anyway.
