NS and I

National Savings & Investments (NS&I) will dramatically cut the interest it pays on many of its savings accounts in November, slashing its top easy-access rate to just 0.01%. And Premium Bond holders will also have a much lower chance of winning a prize from December, with the prize rate to be cut to 1%.

More Premium Bond prizes will be paid directly to holders' accounts as NS&I is set to phase out its paper prize cheques by March next year – so make sure it has your details.

Premium Bond holders will now be able to sign up to get text notifications letting them know when they've won a prize. 

Premium Bond holders will have a lower chance of winning a prize from May, while those with NS&I savings products will see their interest rates cut.
