If you’ve already bought a house you’ll only benefit from a LISA if you’re happy to leave it until you’re 60. It replicates a pension. Withdraw it before then, you lose the bonus & a little bit on top of that. Assuming you’re still at the same employer I think you are, make sure you’re putting your 6% into your pension & they’ll do the 17% & 3% extra (again, I’m assuming you’re on the older scheme?) Even then, because they do salary sacrifice, you’d be better off putting additional money into your pension rather than a LISA as you’ll pay less national insurance. I’m not sure, but your employer might even pay back their NI savings too meaning a bigger contribution to your pension. Also, you can get your pension at 57 (under current rules) but LISA is 60 (could look at that as a good or bad thing).
