As PP have said it is perfectly possible to have a lovely wedding for £2000 or less but not if you want the full bridal magazine experience!
Our wedding was £2000 although we did have a lot of help from family and friends. For example DH's grandma made the invitations as she makes cards anyway. My step mum made the cake (Christmas wedding arranged at short notice so she just used the Christmas cake she had made in September
). Family paid for wedding night in hotel where we had reception (hotel upgraded us for free) and best friend paid for us to have spa treatments. Friend couldn't make it so very generously paid for my dress which was knee length from Coast. Other friend who is a keen photographer took some lovely shots of us signing the register but otherwise we just relied on everyone bringing their own cameras.
The ceremony was in the city hall which is as fortunately a stunning building so definitely worth looking around at your local ones (you don't have to use your most local!). Hotel was five mins walk from city hall so no need for transport. Didn't do flowers.
We booked wedding at short notice and at Christmas. The hotel knew that they weren't going to get anymore bookings at this point so waived the venue hire fees! They also offered a 15% discount on food if we chose the Christmas menu as they already had all the ingredients in. No need to decorate venue as all done up for Christmas anyway.
Meant we were able to provide a free bar (house wine, beers and soft drinks) which was awesome. We got married at 11 and just had a lunchtime reception, no evening do so only one meal required.
Our wedding wouldn't be to everyone's taste but we loved it (and our guests seemed to) and I think we got a bargain. Beautiful ceremony venue. Reception in a lovely 4* hotel. Plenty of food and drink and all really laid back. We didn't do seating arrangements or wedding favours either.
My tips would be to get married out of season. Have the wedding at a time of day that means you only have to provide one meal. Keep things casual. Accept as much help from friends and family as is offered. And if you have the balls boom at short notice to get some great deals!
