What to do with £10k?

[JillyBoel22]

I am due to get a lump sum of circa. 15k and would ideally like to put £10k aside indefinitely for things I plan to happen across the next 4/5 years. I am just not sure where to put it for that time? I would like to be able to access it incase of emergencies/if things happen sooner than I expect (wedding for example!!)
For context I am very early 20s, live with my partner (he bought the house before we met so I am not on the mortgage but we would look to buy the next house together in approx 5 years. I have a good income (circa 2k per month) which will go up (spinal points) across the next few years so plan to add to the 10k as well across time.
What is the best way of putting a lump sum of 10k away without it devaluing over the next 5 years?

If you’d be a first time buyer, the most money you can make on it will be one of those lifetime ISAs for first time buyers

But if you don’t definitely want to spend it on buying a house don’t go for that.

Thank you I think this looks sensible, I had a help to buy isa when I was much younger than has nothing in it (just opened it so I didn't miss the deadline) but this looks better? It seems I am ok to have both aslong as I am only using one.

How easy is it to use the money from the LISA towards a new home purchase if the other part of the deposit is coming from a house sale?

You need to read the key features to work out if it’s right for you. But the website linked above says:

If you're planning to buy a home together, it's important to understand that there's no such thing as a joint LISA: you and your partner/spouse need to open separate ones. Here's how it works:

If you're a first-time buyer making a purchase with someone who's owned before, you can still open one and use it towards a home purchase together, but the partner who's previously owned a property can't open one.

If you're both first-time buyers buying a property together costing £450,000 or less – you can both open one and save in it, essentially doubling the bonus. Note: even if you're both using the LISA, the £450,000 limit is strict. It doesn't double because you're both using the LISA cash.

atom bank have some good savings rates of interest on their accounts - you do need to lock the money away but only for 6 months or 12 months if you feel 2 or 3 years is to long

the interests rates are 3-4% on some accounts and that would pay £435 over a 12 month period and £175 over 6 months

you can always pop it in again for 6 months or a year or at that stage look and see if there are better rates elsewhere

lloyds are offering a regular savings account, you can put in £400 each month and its one year only, Barclays and Natwest are doing similar.
