Where to put 20k?

[LooseyInTheSky]

I've saved £20k.

It's sitting in a Santander instant saver account that is the part 2 to my current account. It's essentially a second pocket - I transfer in and take out instantly as required.

I don't actually need to take out. I've never taken out. The Instant saver gives me basically no interest, no more than a couple of quid every 6 months or so - I'd like that to change.

Any ideas on what to do with this money?

If you're still saving, Santander do a regular savings account that pays 5% if you have a qualifying current account.

the bank will just recommend their own products.

i'd also go for premium bonds. zero risk on capital, better interest rate than banks by winning, and winnings are tax free. i invested a similar amount to you and win every second month i reckon. i've had them for 4 years now and about 1.5k winnings. far far better than interest rate on banks and zero risk to capital unlike any ISA share portfolio. plus people keep going on about a 'correction' of the markets and i do think that will happen at some point.

Get a gonancial advisor as returns in managed investments can be amazing ie between 8-12% a year pm if you need to

Move the maximum each year to a help to buy ISA (if that is the right name?). The government give you 25% top up when you buy your first property. Even if you only do it for a year before buying it's well worth it.
