No, you cannot withdraw 25% of your pension tax-free every year. The 25% tax-free lump sum is a one-time allowance that applies to the total value of your pension when you start taking it, not on a yearly basis. You can take the 25% tax-free lump sum as a single payment, or spread it out over withdrawals, but the 25% allowance only applies to the initial withdrawals from your pension pot. The remaining 75% of your pension, and any subsequent withdrawals, will be taxed as income.
