LISA vs ISA, the honest comparison
A Lifetime ISA (LISA) is an HMRC-authorised account for UK residents aged 18 to 39. You can pay in up to £4,000 per tax year, and the government adds a 25% bonus, up to £1,000 a year free. The catch: you can only withdraw without penalty for a first home worth £450,000 or less, or from age 60. Any other withdrawal triggers a 25% penalty on the amount taken out, which actually claws back more than the bonus you got. A standard Stocks and Shares ISA has no bonus, no penalty, and a £20,000 allowance. The £4,000 LISA contribution counts inside the £20,000 ISA total.
A 25-year-old pays £4,000 a year into a LISA for 10 years. They have put in £40,000, the government adds £10,000, and at ~8% returns the pot is around £75,000 ready for a first home deposit. The same £4,000 a year into a standard S&S ISA would be around £60,000 at the end, no bonus, no lock-in. If the buyer is sure they want a UK home under £450,000, LISA wins. If they might buy abroad, or above the cap, the standard ISA avoids the penalty trap.
Opening a LISA in your late 30s ‘just in case’. You can only contribute until 50, and if you do not buy a qualifying home you cannot touch it without penalty until 60. For most people in that bracket, a SIPP or standard ISA is more useful.
