The 25-year lock-in nobody costs into the SIPP comparison
Pension money is locked. The current minimum access age is 55, rising to 57 from 6 April 2028 and indexed thereafter to State Pension Age minus ten years. A 35-year-old contributing today is buying a wrapper they cannot legally access for 22 years.
A SIPP comparison that ignores this is dishonest. The 40% relief looks great in a spreadsheet because the spreadsheet doesn't show the column titled 'years until you can spend this money.' For a 30-year-old, that column reads 27 years. For a 35-year-old, 22 years. For a 45-year-old, 12 years.
VCTs require a five-year hold to retain the income tax relief. After five years, you can sell the shares — usually back to the VCT manager via a share buy-back, often at a 5-10% discount to NAV — and recycle the capital. That liquidity is worth real money to anyone whose retirement plan involves spending money before age 57.
If your retirement plan involves not retiring at 57 — early retirement, sabbatical, business start-up, house move, mortgage paydown, paying for school fees, supporting elderly parents — that 25-year lock is not a feature. It is a bug. And the 40% relief is the price you've paid HMRC to take liquidity away from you.
