Sainsbury's Bank's savings, credit cards and loans will be taken over by NatWest from Thursday 1 May. For most, this means little will change for now as the Sainsbury's Bank brand will remain, though it's expected to be phased out towards the end of this year. However, if you've over £85,000 saved across both banks, it's worth considering moving any excess elsewhere to ensure your cash remains protected.

If you have a Nectar card, you may be able to earn a few quid's worth of extra points over the next few weeks, as Sainsbury's has brought back its 'shop for points' promotion for some members.

So it's a no-brainer if you were planning to do that anyway.

If you collect Avios – the reward currency of the British Airways 'Executive Club' loyalty scheme – and you're planning to convert them into Nectar points, you should make the swap before Monday 11 March. From this date, the value of Avios being converted to Nectar will be slashed. But only do this if you're sure you won't use your Avios for reward flights, as that can be much more lucrative.
