To ask what to buy as a wedding present for a couple who have been together 15 years and have two kids?

[Thepeopleversuswork]

Very settled, don't want for a great deal in material terms, own their home and loads of nice stuff in it so no obvious need for typical wedding presents and I don't think they would want that.

Want something which is significant for both of them and something which is appropriate for a wedding but they aren't making a fuss of the wedding; it's a small civil service. I don't think they'd like anything obviously commemorative or "weddingy" if that makes sense ie crockery or jewellery. They are big readers, outdoorsy. Neither particularly materialistic. Two kids approaching teen years.

For a friend in a similar situation I got them a gift voucher for their favourite restaurant. (The Ivy).

If they have a garden I’d get them a rose or a small tree.

Do they have a favourite artist or designer? Could people club together to get something like that?

First edition books maybe or a photo frame of them on their wedding day / very nice bottle of champagne or a day trip / event / tickets

We said we didn’t want anything for our wedding and we really meant it! If you want to get something I would go for champagne.

The best wedding presents we got were vouchers for: John Lewis, dunelm (although you can’t use them online so would steer clear in future), next, Dobbies and a voucher for a spa day or meal out is amazing too. Things like that you don’t think as much of when you first open but it’s such a treat when you can go for a meal for free

It's not about the gifter, it's about the giftee and what they would want. Are they going to want multiple silver frames, towels, bedding, random gardening stuff? It's very likely if they wanted any of that in their home they would already have it. And vouchers (which are essentially money but much more restrictive) is ok if you know they regularly go somewhere or are saving for something from somewhere but really it's just more agro for the giftee than cash isn't it? Most couples have a honeymoon, surely cash they can spend on it is far better than a random gift or 20

They still kinda are, 20 quid or 100 for a shop you don't need anything from is still a waste, you just have more to waste there

In similar circumstances I bought an expensive photo frame, by that I mean not from The Range as most of mine are, they were delighted as they had new wedding photos to display.

OP I'm going to assume that if you knew these people well enough to know that they LOVE a particular restaurant, or artist, or membership etc you wouldn't be asking on here.

So stick with something generic that doesn't box them into having to do or use something that just isn't wanted. If not money, then either vouchers for something very flexible (John Lewis or Viator was a good shout if they are honeymooning) or a consumable e.g. top notch food or drink if you know what they like.

If you do get vouchers for something specific, make sure it will cover the cost, e.g. not a 50 pound restaurant voucher if a meal there is going to cost 120 minimum!

Consumables, from what you've said, would surely be easier for them?

Nice wine, champagne, nice gin, nice rum - whatever they drink.

Voucher for a meal out - even Pizza Express or something if they want to take kids with them.

An afternoon cookery course? Followed by a meal in the hopefully nice restaurant.

In their position, the very last thing I would want is more ‘stuff’. In particular, if someone bought me stuff which had to be put on display, eg a painting I had not chosen myself, I would be furious.
I would be very happy with wine, cash or vouchers for hotels, restaurants, concert tickets etc etc.

If I know a couple wants vouchers/money/experience/not physical gift I would give that happily

If not, an actual gift

Vouchers for the local cinema. They could use them as a couple or as a family.
