This is a tough thing to answer.
I realise this is a bit of a cop out but it really does depend. It all depends on one thing. Your budget.
If your budget is £35,000 you'll have a very different amount of money to spend compared to someone who has a £100,000 budget. That's why budget is everything. Once you know your budget, you can start thinking about how much you have to spend on the suppliers.
Most people will then show you a similar breakdown to the one below.
Everything else: 8%
This is great, in theory.
The problem arises when you want to have a wedding that is different to everyone else's. If you are sticking to the same budget breakdown as everyone else, then your wedding will end up looking very similar to everyone else's. That's not what you want.
It's your wedding day and you want to make sure that your guests remember your day forever, instead of getting it mixed up with the wedding they attended the month before.
That's why I created this super simple Spreadsheet.
When you download it (no strings attached) you'll see you get to choose how much you want to spend on each part of the wedding day. You decide what is important to you.
I could tell you what I think is important but, A) I am biased and B) It's not my wedding.
I would tell you than entertainment is the most important thing but a cake maker would argue that the cake is the most important thing. It's ultimately down to you.
With this Spreadsheet you decide what you want to spend your money on.
Of course you can chop and change the Spreadsheet to suit you and your wedding. That's why I created it the way I did, to allow you to get exactly what you want out of it.
All the best,
