Planning Your Wedding Budget
The average UK wedding costs around £21,000 — but that figure hides enormous variation. Couples in London regularly spend £30,000 or more; those in Northern Ireland or Wales can achieve a full wedding day for under £15,000. What matters is not the national average but your number: the figure that works for your circumstances, your priorities, and your guests.
Getting that number right early changes everything. Once you have a realistic budget, you can allocate it sensibly across venue, catering, photography, and the rest — and avoid the common trap of spending heavily on the first few decisions before realising there is not enough left for everything else.
Our Wedding Budget Calculator gives you an instant breakdown across every cost category, benchmarked against UK national averages from Bridebook and Hitched. You can adjust the percentage allocated to each category to match your own priorities — more on photography, less on flowers, for example — and export the result as a CSV.
The Guest Cost Calculator approaches the budget from a different angle: what does each additional guest actually cost you? For a catered wedding, each extra person typically adds £200–£350 to your total. Understanding the marginal cost per guest helps you make difficult decisions about your guest list with clear eyes.
Both tools use UK-specific data — prices in pounds, national averages from UK wedding surveys, and cost splits typical of UK weddings rather than US or European conventions.
