Martin Lewis says Nationwide, Lloyds, Co-Op and First Direct giving out £661

Money expert Martin Lewis says savers can get a total of £661 of interest with four regular savings bank accounts from First Direct, the Co-Op bank, and .

And in this case, every saver can get all £661 because there's nothing stopping you from opening all four accounts at the same time and claiming at least one switching bonus, meaning you max out your interest and get paid a switch bonus on top.

Returning to the Money Show Live on and ITVX, Martin took his audience through his top savings tips.

And he revealed that four big banks - First Direct, the Co-op, and - are offering the best high interest regular savings accounts on the market right now.

Right now, First Direct has a 1 year fixed 7 percent account which allows you to save a maximum of £300 per month for £137 interest after one year.

The Co-Op also offers 7 percent on up to £250 a month for £114 interest, Nationwide offers 6.5 percent for one year up to £175 a month for £85 interest and Lloyds offers 6.25 percent fixed for a year on up to £400 a month for £150 interest.

These are regular savers, which means you put money away each month, up to a maximum deposit, and are then paid interest throughout the fixed or variable period.

Coincidentally, all four banks also offer bank switching bonuses of between £75 and £200, so you may be able to get more money on top if you switch your current account to one of these four banks and tap into the linked savings on offer.

But even if you don't do that, there is nothing to stop you from opening all four accounts separately and maxing out each one's interest to collect £486 if you have enough spare regular monthly income to do it.

Martin explained: "This is where you get the highest interest possible, these regular savings accounts up to 7 percent. But it is on smaller amounts, but you could use two or three of them to combine and then you could be putting £6/700 quid away each month.

"They're designed to put spare income each month in if you have it. If you're lucky enough to have two or three hundred quid each month spare, you put them in here.

"The top four interestingly are all with banks paying to switch your current account and you need a current account to link to, and these are paying up to £175 to switch so you might want to have a look at that as well.

"The one that pays more has the lowest rate of the four. Why does it pay more? Because you can put up to £400 in it so that gives you £150 worth of interest."

Therefore, if you opened all of the accounts, maxed the interest for a year and got at least one switching bonus at £175, you'd be paid £661 by the banks in total.
