Wedding Gift. How much?

[HibbidyHobbidyHoo]

My DH and I have been invited to one if my friends weddings. They seem more financially comfortable than we are. I've been on maternity leave so our income has been massively reduced, along with our much wanted extra mouth to feed and the cost of living becoming ridiculous I'm not sure what to do re a gift.
Their wedding isn't going to be held at any expensive venue, it's actually in the barn of her parents and it's a buffet so not a big 3 course meal event. But I understand this doesn't necessarily mean they've done it on the cheap either.
Their card says no gift required but happy for money sort of thing.
I will be going back to work soon but only part time and money is tight.
Would £30 and a £5 keepsake be OK or offensive? We're not old old friends.

Yes, I think so. I did similar for a neighbour when she got married.

If money is tight, that is perfectly fine.

If money is tight then definitely just give what you can afford. I tend to give £50 for friends and £100 if it's family.

It says no gifts but people still do gifts - can you re-gift a bottle of bubbly?!

I'd give a bottle of champagne.

£5 keepsake sounds like a waste of money.

£30 is very generous in the circumstances. But if you don't feel comfortable giving an amount of money when it doesn't sound like they need it, then how about a bottle of fizz if you know they like it. You could spend £10-15 on a bottle of Cremant and it's more special than standard cava etc and just as good as champagne at 2/3 times the price.

Or you could actually take them at their word and not take a gift. They could genuinely not want anything and will despair if people ignore this and turn up with armfuls of photo frames, Mr & Mrs tat etc.

I recently got married and about a third of the gifts were cash or vouchers of approx £30. I was very happy with these!
