Savvy savers have just four days left to pocket up to £310 from TSB - one of the most generous current account switching incentives on the market.

The high street lender will pull the plug at 11:59pm on Monday, June 30, meaning anyone hoping to cash in must start the switch by then.

The deal, which is open to both new and existing customers, offers up to £190 in cold hard cash, plus rewards worth up to £120 in early 2026.

To qualify, switchers must move to either the TSB Spend & Save or Spend & Save Plus account using the official Current Account Switch Service. Crucially, the process must be fully completed by 19 July.

Applications can be made via the TSB app, online, or in branch - and existing TSB customers with other products, such as a mortgage or credit card, are also eligible if they open a new current account and switch into it.

The Spend & Save account is free to open, while Spend & Save Plus charges a £3 monthly fee.

As with many bank switching deals, there are a few hoops to jump through to unlock the full reward - and TSB is clearly targeting customers who plan to use it as their main account.

To unlock the initial £100 bonus, switchers must:

• Use the TSB Mobile Banking app
• Make at least five debit card payments before 19 July 2025

The £100 payout will then land between 2 and 16 August.

The benefits of the deal do not stop there. New customers can earn £15 cashback each month for six months - a further £90 - by making 20 debit card payments per month.

In a final sweetener, customers who meet the above criteria and hit 20 debit card payments in December will unlock a choice of two January rewards: either a £120 hotel voucher (UK or abroad) through Travel Credits, or a 12-month pass to UK activities such as escape rooms, kayaking, theme parks, and museums

While the rewards don't arrive instantly, the headline figure of £310 makes TSB's offer the most lucrative on the market right now.

Rival First Direct is offering £175, with payment within 45 days of switching.

NatWest offers up to £175 - made up of £125 for switching, plus another £50 for opening a linked regular saver.

Experts warn that chasing switching bonuses should never be the only factor.

Would-be switchers are urged to check for hidden fees, branch access, and customer service reviews, to ensure the account actually fits their needs.
