Church donation

I think the church will be grateful for whatever you can give, but as a minimum, try to cover costs (in November, I'm assuming the church will be heated plus of course there will be cleaning to be done) and a bit more if you can. I don't know if the church is providing the minister and if he/she is speaking, but if so, bear in mind not just the time they take at the service, but the time spent in preparation too. By the time they have prepared a message, met with you to plan, perhaps done a wedding rehearsal plus officiated on the day, it's probably at least a full day of their time.

We are getting married in a catholic church and our costs come to £400 (not as a donation), this covers the ceremony, the priest and all legalities and then the organist who is playing the music x
