Sir Tony Baldry, the Second Church Estates Commissioner, recently gave this written answer in the House of Commons to a question on the cost to visitors of accessing religious buildings.
Religious Buildings: Fees and Charges
Dr Offord: To ask the hon. Member for Banbury, representing the Church Commissioners, what recent assessment the Church Commissioners have made of the cost to visitors of accessing religious buildings. 
Sir Tony Baldry: Of the 42 Dioceses in England (excluding Sodor and Man and Europe) only nine cathedrals charge an entry fee. Chester Cathedral has just abolished all entry charges. Unlike the national museums none of the Church of England’s cathedral or church buildings receive grant in aid from the Government.
All cathedrals which charge for entry give free access to those attending services (of which there are a number every day of the week), to those who arrive on pilgrimage or wish to pray, some give free entry on Sundays and at other times, generally early in the morning or late in the afternoon, and others give free entry to local residents or church attenders in their Dioceses.
Only two of the great parish churches charge entry fees or a modest charge to enter part of the church. They are St Bartholomew’s the Great in London Diocese and Holy Trinity Church, Stratford upon Avon in Coventry diocese the resting place of William Shakespeare.
Both the churches and cathedrals resort to charging primarily to recover the cost of repairing the fabric of the building due to the large volume of tourist visitors they receive.
The English Cathedrals and Royal Peculiars that currently charge for entry as of June 2013:
Christ Church, Oxford (to enter college)
St George’s Chapel, Windsor (to enter castle)(1)
(1) Royal Peculiar
