We spent £4900 including the cost of the honeymoon. We had 120 guests. We didn't have an evening do - left on honeymoon at about 5pm, after the reception. Our honeymoon was UK based and just a few days long, then we came back and spent the rest of the week quietly together at home, which was lovely.
Other places we saved money:
Rings - my engagement ring was vintage (1930s). We bought the wedding rings online from Bay Rings, which had the best prices for gold at the time.
Invitations and orders of service - I designed these and got them printed locally.
Monsoon wedding dress.
Secondhand wedding shoes from eBay.
Sparkly little secondhand tiara from the market.
We were lucky with the venue - local country park that has a big posh house where they do a full wedding package. They also have a much more ordinary cafe with tons of space, so we hired that instead and got the gorgeous country park setting without the massive price tag.
My cousin is a florist so she made the bouquets and buttonholes as my wedding present, and also advised me which flowers to buy as centrepieces for the tables. I bought the flowers from the local wholesale place and the people at the venue kindly plonked them in vases for me.
We had a buffet rather than a served meal. There was plenty of food, hot and cold, and it seemed to be a success! They charged £10 a head per adult, half price for kids.
We paid for one drink per person - prosecco/juice on arrival - and then people bought their own drinks.
Music - I had a singer, a guitarist and a violinist. The singer did it as a wedding present as she's a friend. The violinist did a skills swap with me and her friend played the guitar for £50.
I went to a local youth enterprise which is trying to help young people set up their own businesses, and I got a hairdresser to do my hair and two bridesmaids for £85.
I found a fairly new photographer who is still developing her profile and experience. She photographed the wedding and did about an hour of posed shots of us and the guests for £100.
We bought small presents for everyone who took part, e.g. parents, ushers, bridesmaids, but no wedding favours for guests.
My uncle drove me to the venue and my husband drove us off on honeymoon in his van, so we only paid for ribbons.
My MIL made the cake.
Spent a lot of time looking on eBay for bargains, and kept focused on the fact that we wanted a large number of people there and so that was where the bulk of the money would go (food, drink, large venue) rather than tiny details that are soon forgotten.
I think it made a big difference that we didn't want an evening do. That would have really bumped up the cost because of a DJ, more food, etc. We really enjoyed being waved off by all our friends and family and then whizzing off on our secret honeymoon!
