The banking giant announced that from today, all personal current account customers are eligible to open its Regular eSaver account paying 2.5% AER/gross for 12 months – up to £32.26 in interest.

It allows savers to pay in up to £200 per month, with a maximum annual balance of £2,400.

Previously, it was only available to 1|2|3, Select and Private Current Account holders, but now, those with the Everyday and Basic current accounts will be able to open the regular saver. It excludes the 1|2|3 Mini In trust customer accounts.

Santander said the move will benefit 5.4 million UK customers. It comes after it last month increased the in-credit interest rate on its 1|2|3, Select and Private current accounts from 0.5% AER/gross (variable) to 0.75% AER/gross (variable) on balances up to £20,000.

And as of today, it has also increased interest rates across the board:

• 1 Year Fixed Rate Bond will increase from 0.7% to 1.5% AER/Gross
• 2 Year Fixed Rate Bond will increase from 0.9% to 2% AER/Gross
