What to buy with £100k?

Not this again. There are no tax implications to gifts of any size in the UK, unless the person dies within 7 years of the gift in which case there might be an IHT liability (calculated on a sliding scale)

I'm jealous.

If it were me I would put it into a house deposit for each child and rent them out to pay the mortgage 🤷‍♀️

My dream when my children were young was to buy a piece of land. Slightly laughable in my situation but that's not the point.
You can use it to grow an orchard or woodland, build a bird hide, go metal detecting, camp out, learn bushcraft, put up hammocks, escape from the world. Eventually you could either sell it and give the kids the money or put the land in trust for the next generation. It won't be the best investment but it sounds like your children are already financially sorted.

Premium bonds up to £50K each, A bit of fun each month getting wins, at the minute maybe a couple of hundred a month average (pocket money, or into other savings), and the possibility of that big one.

Edit: I got £250 on £25k this month, my DD got £1,750 on £50k last month although that was pretty exceptional!

Junior savings or investment for a mortgage. ( But some which you can dip into if the university situation at the time requires it or they develop an expensive hobby or they want to do a ski trip with school)

Could use some also for family holidays to give them experience on the other hand that would likely involve flying which is bad for the environment. You could benefit them most if you gave the £100000 to an environmental charity to plant trees or save the pear bog and you could visit every year to see developments

Start their pension fund and give them a head start.

Take them to see Taylor Swift? Taking into account the ridiculous ticket prices and inflated accommodation costs, it should just about cover it... 😉

I think you only pay tax on a gift if the person who gave the money dies within 7 years and then the gift falls within inheritance tax. But the amount of tax tapers depending how close to the 7 years they survive.

You can also gift £3,000 a year tax free (outside the inheritance tax rules) and carry over the allowance from a previous year, so if you don't do it regularly you can gift £6,000 in any one year.

I’d invest it in some way. I do like the charity idea though, especially as you seem to be a very fortunate family financially. Could you put a portion aside of any interest/ income received on the investments and each DC could choose a charity to donate that to?

If DC don’t need it now, just fill up the ISA allowances and invest it in a couple of low/ medium risks until they do need the money. And a bit in a pension, which they’ll thank you for in a few decades. I know they’ve got investments already, but it’s not like they’ll get to 30 and think ‘damn, I’ve just got too much money invested.’

I really wouldn’t buy a house in France. As a half French, British resident owner of a house in France, I can assure you, they are a bit of a ball ache even when you know the system and speak the language. Do you really want to spend precious time off in M Bricolage looking at mousetraps?

If you want to invest in property, there’s no need to buy an actual property, just put it into a property fund.

I wouldn’t do property right now.
Travel. Not a 1/2 week holiday for a half term break. Take unpaid leave from work with DH and travel through the 7 week holidays.

House deposit as a child’s isa won’t cover both university and house deposit.

I could use a few quid, help my son.

Or many charities need help.

Who was this declared to? I honestly can’t think how this would arise. No tax implications on a gift as far as I am aware unless you’re posting from the grave.

50k in Premium Bonds - probably for a regular monthly win.
50k on holidays

I would buy a holiday home abroad. Probably in France, Spain or Italy, all of where you could definitely get something for 100k. Gives them the joy of holidays there now / in their youth and an asset for later. My parents did this (although it was an inheritance rather than a gift) and we’ve had happy holidays there since.

Can parents open a pension fund or do the children have to do it?

Then save it in your names in the stock market but earmark it for each child. Transfer it to a LISA when they’re 18.

Pensions? I wouldn’t gift my children something they may never live to see.

How old are the children?

But also, the very last thing I'd do is put it in an investment/BTL property at the moment. It will be so much hassle and is likely to become even more hassle.

Honestly, property isn’t a great investment now. It comes with significant running costs and regulations if you rent it, there’s capital gains tax when you sell it, and it’s not easily divisible if your children are at different life stages when they want to buy their own homes.

Put it in ISAs!

I’d bought into ISAs and have an amazing holiday but perhaps you already spend 20k on holidays
