How much should you keep aside?
A sensible rule is to keep around 10% to 15% of your total wedding budget aside for hidden or unexpected costs. For a £20,000 wedding, that means keeping around £2,000 to £3,000 as a buffer.
This does not mean every couple will need the full amount, but it helps avoid panic when smaller costs start appearing in the final weeks before the wedding.
