There is no specific limit on the number of pensions you can have – and you can pay into pensions of different types, such as workplace pensions, private pensions and state pensions, as long as you meet the eligibility criteria for each type. However, the total amount of pension contributions and benefits you receive from all your pensions may be subject to annual and lifetime allowances set by the government, which may affect the amount of tax relief you can claim and the amount of tax you may need to pay. It's advisable to seek professional financial advice from experts like KGJ to ensure you understand the rules and regulations regarding pensions and can make informed decisions based on your individual circumstances.
