You might be able to benefit from additional or matched contributions through other employer pension schemes. Make sure you know what’s on offer to help you save.
There are limits to how much you can tax-efficiently contribute (the Annual Allowance) and save in pension savings (the Lifetime Allowance).
To give you an idea of the impact of compound interest:
For every £1 a 20 year old pays into their pension, someone starting their pension aged 30 would have to pay £2, a 40 year old would need to pay £4 and if you’re 50 you’d have to pay £8 to get the same amount of savings in retirement.
