Good savings or family help £15,000 - £25,000

Account Type Why
Regular saver (5%+) Best rates for monthly deposits
Easy access (4%+) Flexibility for deposits
Joint account Both contribute, both access
Cash ISA Tax-free interest

Tip: Open a dedicated wedding savings account so you don’t accidentally spend it.

When NOT to Spend More

Temptation Why to Resist
“It’s a once-in-a-lifetime day” Debt lasts longer than one day
“Our parents expect it” Have an honest conversation
“Everyone else spends this much” Your finances are unique
“We’ll pay it off after” Life gets more expensive (house, babies)
Wedding loans Starting marriage with debt

Family Contributions

Having the Conversation

Approach Example Script
Be direct but gracious “We’re planning the wedding and would love to know if you’d like to contribute, and if so, how much we might expect”
Set expectations “Whatever you give is a bonus, not an expectation”
Clarify strings attached “Would a contribution come with specific expectations about the wedding?”

Managing Contributions

Situation Handling
Contribution with demands Decide if demands are acceptable before accepting
Different contributions from each family Keep it private between you
Promise not delivered Have a backup plan; don’t over-commit
Offered more than needed Consider declining excess politely
