Not sure how much you can really save but here they are. I would advise others to not over do some of the ideas because you just look really tacky and cheap:

Buy the plain white iced cakes from Marks &Spencer or similar and decorate with fresh flowers

Buy bridesmaids dresses from ebay or Monsoon/Coast in the sales

Rope your friends and family with any skills in to help - decorating rooms, floristry, neat handwriting for invitations and name places, musicians, people with nice cars to drive you, people with big gardens, photographers, needle workers to make dresses or cravats etc etc

Move flowers from the ceremony venue to the reception

Make your own favours

Have a hot fork buffet or similar instead of a sit-down meal

Maybe ask for holiday vouchers as wedding presents - This will then pay for your honeymoon.

Buy a white dress, not a wedding dress. This will be significantly cheaper than buying a wedding dress where the mark up is incredible.

Buy a secong hand dress - Or get a shop bought one from possibly Marks and Spencer or Monsoon. Or you could try Oxfam Bridal shops - They sell new as well as used dresses.

If you don’t want to go as far as buying a second-hand wedding dress, you can still save £££s by buying the extras (tiara, veil etc) from eBay.

Don’t include RSVP cards with the invites.

Ask for things like guest books and wedding albums to be your wedding presents.

Have candles instead of flowers as centrepeices.

Don’t have BM’s or Ushers.

Do your own make-up.

Set up your wedding list at Debenhams and you get a free £50 giftcard - regardless of whether anybody uses it or not.

Look for a free wedding website

Having a wedding somewhere more out-of-the ordinary but cheaper, like Gretna Green, isn’t actually a bad idea!
