Investment advice - £30K

[Robw73]

I am due to receive a lump figure of £30K in the next few weeks.

I will need this money towards my next mortgage, but until that day arrives, any advice to the best, safe investments would be greatly appreciated.

With very minimal research I am thinking:

£20K Premium Bonds
£10K Santander 123 account.

Any thoughts / recommendations welcomed.

Thank you.

When do you need it for your mortgage?

Tricky question to nail down exactly.
2 - 4 years at a guess.

To resurrect this thread, the funds are due to me in about 3-4 weeks.
I've discovered some high(ish) accounts for smaller amounts, TSB & Nationwide, any other options that I should be reviewing?
