My husband and I got married 2 years ago and we kept the cost down by not getting married in the UK, but in Sweden (where I am from). I think that as soon as you mention the word wedding here, the cost doubles. Specially in London! We spent less than 10K (which for us is a lot!!) and had a beautiful wedding with approx 80 guests. We got married in a church from 12th century, then had the reception at a hotel which we had to ourselves by the third biggest lake in Sweden. The staff at the hotel set the table and decorated so we did not have to worry about that. We had transport from the church for ourselves and the guests, a three course meal including bubbly and canapes, staff that served all the meals, wedding cake, coffee and whiskey, free bar all night and a live band.... I'm pretty sure the same wedding in England would have been over 20K!
