Pensioners across the UK have gained from an income boost after the State Pension was uprated by 4.1% in line with the triple lock.

The uprating, which took effect at the start of the new financial year in April, has increased the full basic State Pension up to £176.45 per week, while the full new State Pension is now worth £230.25 per week. The Department for Work and Pensions (DWP) has said the increase will provide an extra £360 per year to those who get the full basic State Pension, while the new full State Pension will add an to pensioner pockets.

As the new tax year begins on April 6, some pensioners won't have got a full month on until May, meaning many will only have had one full month to fully benefit from the uplifts.

Payments in May were disrupted due to two bank holidays, forcing the DWP to send money into bank accounts earlier than normal. But State Pension payments will be going out as normal in June as there are no bank holidays this month.

The State Pension is typically paid every four weeks and when you first claim it, you choose the date when you want to receive your payment.

Pensioners can determine their usual State Pension payment day by looking for the two digit code at the end of their National Insurance number, as this specifies the date on which payments are issued. This is how National Insurance numbers correspond to payment days:

• 00 to 19 - paid on Monday
• 20 to 39 - paid on Tuesday
• 40 to 59 - paid on Wednesday
• 60 to 79 - paid on Thursday
• 80 to 99 - paid on Friday

So if your National Insurance number ends in 00 to 19 then you will be paid on a Monday in June, while those with numbers between 20 and 39 will get their payment on a Tuesday, and so on. Whether this is at the start of the month or towards the end depends on the date you selected to get your first State Pension payment.

The DWP explains: "You'll be asked when you want to start getting your State Pension when you claim. Your first payment will be no later than 5 weeks after the date you choose. You'll get a full payment every 4 weeks after that.

"You might get part of a payment before your first full payment. The letter confirming your State Pension payment will tell you what to expect.

"The day your pension is paid depends on your National Insurance number. You might be paid earlier if your normal payment day is a bank holiday."
