How to Save for a Wedding Without Wrecking Your Finances

UK wedding costs have levelled off slightly after years of steady increases, but they remain a genuinely significant financial commitment for most couples. Here’s the current picture, and a practical way to fund a wedding without taking on expensive debt.

What weddings actually cost in 2026

Two of the UK’s most-cited wedding surveys put the average cost of a UK wedding in 2026 at £20,604 (Bridebook) and £21,990 (Hitched) respectively - figures that have broadly flattened rather than continued the sharp rises seen in recent years. Costs vary considerably by region: London weddings average around £24,600, while weddings in Wales average closer to £15,500. The average cost per guest is around £272, meaning guest list size is one of the biggest levers on total cost.

Most couples are trying to avoid debt for this

A NatWest survey found that 81% of couples said they’d rather delay their wedding than take on debt or borrow to fund it, and UK couples are now engaged for an average of two years and four months - giving considerably more time to save and plan than a shorter engagement would allow.

Where to actually keep wedding savings

• A dedicated Cash ISA or high-rate easy-access account - see our dedicated comparison article - keeps the money separate from everyday spending and earns interest while you save, rather than sitting in a current account earning little or nothing.
• A regular saver account can work well if your wedding is roughly a year away and you can commit to a consistent monthly amount (see our dedicated article on how these work).
• Avoid locking wedding savings into anything you can’t access on your wedding date - a long fixed-rate bond that matures after the big day defeats the purpose.

Practical ways to reduce the total without feeling like you’ve compromised

• Choose an off-peak date. A Saturday wedding averages around £22,290 versus roughly £16,273 for a Tuesday - a meaningful difference purely from day-of-week choice, and Saturdays now account for less than half of all UK weddings, down from around 55% a decade ago, as more couples embrace weekday dates.
• Be deliberate about guest count, since cost scales closely with headcount - weddings with 101+ guests average around £35,591, roughly 40% more than smaller celebrations.
• Consider what’s genuinely important to you as a couple, since venue and catering together typically account for 40–50% of the total budget - trimming elsewhere while investing in what matters most is a common, sensible approach.

If you do need extra funding beyond savings

Around six in ten couples receive some financial contribution from family, according to Hitched’s survey data. If you’re considering a personal loan for any shortfall, representative rates on unsecured personal loans have varied considerably by lender and amount - compare the total cost carefully (not just the monthly repayment) before committing, and be cautious of high-APR options like buy-now-pay-later schemes for larger wedding purchases, since these can carry considerably higher effective costs than they first appear.

A simple savings plan

• Set a total budget first, based on a realistic guest count and priorities, before falling in love with a venue that stretches beyond it.
• Divide the shortfall by the number of months until the wedding to get a monthly savings target.
• Automate the transfer on payday, into a dedicated account separate from everyday spending.
• Revisit the budget periodically, since costs (particularly catering and venue) can shift as you finalise supplier bookings.

The bottom line

A wedding is a significant but plannable cost, and most UK couples are actively avoiding debt to fund theirs. A dedicated, interest-earning savings account, a realistic budget set before venue-shopping, and a deliberate choice about date and guest count are the most effective levers available. Once the wedding’s paid for, many couples simply redirect that same monthly saving habit toward their next goal - worth revisiting whether that money is better used overpaying a mortgage or kept in savings if you’re already a homeowner.
