One of the easiest ways to earn a little cash is to get a cashback current account for your bills.

There are lots of good reasons to switch your bank, including cash bonuses, high interest, fee-free travel money and low-cost overdrafts.

One feature that’s also available is getting cashback on the bills you pay. So you could get 1% back on your Council Tax, or 3% back on your mobile phone bills. It’s stuff we all pretty much pay, so I think it makes sense for us to all have one of these current accounts.

There used to be four separate banks accounts from three banks – Natwest, RBS and Santander – all offering varying rates of money back on your regular bills.

But after Natwest and RBS dropped this reward in February 2020, it’s now down to just two – both from Santander.

There’s the full 123 account, and the more limited Santander 123 Lite. And changes introduced on 5th May 2020 mean both could pay out less than before. So which is better?

Santander 123 cashback current accounts

First a look at what they both offer.

What’s changing to the Santander 123 accounts?

A new £5 cap has been introduced to each part of the cashback. So there’s a maximum of £5 every month on the bills earning 1%, another £5 on those earning 2% and a final £5 on the bills making 3%.

For most people this won’t make much difference as you’d need quite high bills to exceed the section caps.

However, if you have a Santander mortgage then you will likely find you’ll lose out in the new system.

The other big change is that interest on the main 123 account drops from 1.5% to 1%.

How much can you make in cashback?

it all depends on the size of bills. If you’re a high bill payer, you’ll get more. But if you’ve been savvy and shopped around to get the best deal, you’ll earn less. 

My Council Tax is quite high, but elsewhere I’ve got great deals on broadband and mobile phones, switched frequently for energy and ditched pay TV years ago.

I was with Natwest before it closed the cashback offering on bills, but with Santander I’m likely to get £5 ish back before fees every month.

The biggest earners though are those with a Santander mortgage as there’s 1% back (up to a limit of £5 a month).

There’s a calculator you can use to work out how much you’re likely to earn with each account on the Santander website. Scroll down the respective pages and expand the section called “Interest and Cashback” or “Cashback”. The calculator will then appear.

What are the main differences between the 123 and 123 Lite accounts?

The big difference between the accounts is that you don’t get any interest on the balance in your account with the 123 Lite account. However, that’s reflected in a much lower monthly fee – down from £5 to £1.

There are also a few extra hoops you have to jump through for the 123 Lite. You’ll need to log into internet banking at least once every three months, and you need to choose paperless statements.

Which is the best Santander 123 account for you?

Previously the choice between the Natwest or RBS Reward account and the Santander options was down to your own circumstances.

Depending on what bills you had and how much they were the amount of cashback you’d get back would be different at each bank. For that reason I chose Natwest rather than Santander.

However now the choice on cashback is now much easier. The cashback you’ll earn on both the 123 and 123 Lite will be exactly the same. So it’s the other features which really matter.

Obviously the main difference is that 1% interest on savings. However you can do better than this interest rate elsewhere with other current accounts or in savings accounts. And none of those come with a £5 monthly fee,

In fact, the £5 fee will wipe out the interest on the first £6,000. Put that amount and anything above it in a different account earning the same 1% (though you can do better) instead and you’ll make an extra £4.98 a year.

I think it’s a no brainer to go for the 123 Lite out of these two accounts. Yes you’ll need to check the online account every three months but most people should be fine with that.

What to watch out for

Though the categories of cashback are quite broad and cover lots of bills, not every supplier will be included. For example Giffgaff doesn’t appear in the eligible supplier search form.

Also, if you split bills with a partner or housemate then you won’t get the full benefit of this type of account. You could open up a joint account for these key bills, though there are risks you need to be aware of.

How new customers can open a 123 Lite account

You can make applications for the Santander 123 Lite account online, on the phone or in branch. Online is easiest.

Some banks require you to switch to get incentives, but to take advantage of cashback on your bills you don’t even need to close your existing account.

You can simply open up a new account (there’s no limit to the number of current accounts you can have – I’ve got 14!)

You  will need to transfer over your Direct Debits, but you can opt for a “partial switch” when you apply. Here you choose which direct debits you want to move, and this leaves your old account open.

Of course, if you don’t fancy having an extra account you can go through the full switch which does this automatically.

If you don’t go via the switching service at all then you do have to manually move over all your direct debits. To do this you’ll need to contact each bill provider with the new details and make sure the old Direct Debits are cancelled.

How existing Santander 123 customers can downgrade to a 123 Lite account

You absolutely should downgrade your account as there’s really no benefit to the main 123 account. 

If you currently have a 123 account then it’s fine to downgrade your account to a 123 Lite. You can do this online in your account, or you can phone up the bank or go in branch to do this.

If you are struggling to do this due to the lockdown then one solution (suggested by reader Mike) is to open up a new 123 Lite account (or any other account) and then switch the existing 123 account into this. That’ll take around 10 days and will mean you don’t have to wait for things to get back to normal.
