My advice for a budget wedding:
1) Think about your guest list..... you'll be able to have more people in a more relaxed pub / buffet style reception, but if you want something more formal, you will have to invite less people. A small guest list will keep the price down drastically.
2) DIY - there are some things that can be so much cheaper if you have the patience to make things yourself. Invitations - you could be looking at £400!! Pop down to your local craft store and get some cards and other bits and bobs and you can make some gorgeous invites yourself. Favours - why spend £200 on things that people may not appreciate. Bake some cookies or cakes and wrap them in some clear plastic. Tie on personal name tags and you have homemade favours!
3) Call in favours from everyone else - do you know someone who is good at make up?! Hair? Baking? Photography? If you can get someone to do all the things that add up, you notice a massive difference.
4) Bridesmaids - have one or two. The more bridesmaids, the more expense on dress / shoes / make up / presents etc. Or, if you want more, ask them if they mind buying their own outfits. However, then you can't really dictate what dresses they will wear.
5) With the food, have 2 courses. Replace your dessert with your cake! Ask the venue if they will do one reception drink instead of two, or limit the amount of wine on the tables. Every little helps.
6) Weekday wedding - most places will be significantly cheaper on Monday - Thursday. This includes suppliers who might offer midweek discounts.
7) In season flowers - if you love a flower, but they are out of season, you may have to have them imported. And this can triple the price! Talk to your florist about it!
7) This is the best one..... HAGGLE!!!!! A lot of places will help you out with prices to get your business. Research and find out where you can get things cheaper - if you like a supplier more than another, tell them that you can get it cheaper elsewhere and they might budge!
Good luck!!!!!
