If you need to get old payslips in the UK, there are several ways you can go about it:
Contact your employer: The first step is to contact your former employer and request copies of your old payslips. They may be able to provide them to you directly or direct you to the relevant department or third-party payroll provider.
Check your email or online accounts: Some employers may provide employees with electronic copies of their payslips through email or online accounts. Check your email and any online accounts you may have had with your former employer to see if you can access your old payslips this way.
Use a third-party service: There are also third-party services that can help you obtain copies of your old payslips, often for a fee. These services may be useful if you are unable to obtain your payslips through other means, but be sure to choose a reputable provider. Order Replacement Payslips Online
Check your bank statements: Your old payslips may also be included in your bank statements if you were paid by cheque or direct deposit. Check your bank statements for the relevant periods to see if your payslips are included.
Request a copy from HMRC: If you cannot obtain your old payslips from your former employer or through other means, you can request a copy from HM Revenue and Customs (HMRC). To do this, you will need to contact HMRC's Employer Helpline and provide your personal details and employment information, including your National Insurance number and the relevant tax years.
It's important to note that employers are legally required to provide employees with payslips for each pay period, so it's worth checking with your former employer first before exploring other options. Additionally, you may be able to obtain your payslips more easily if you have kept copies of them yourself, so it's a good idea to keep track of your payslips as you receive them.
