Your result
What reaches your deposit?
Your counted price of £465,000.00 is over the £450,000 cap, so a 20% charge applies: £2,840.00 of your £14,200.00 goes back, and £11,360.00 reaches your deposit. That covers what you paid in; investment losses and pending bonuses can change this. Getting the counted price down £15,000.00 to £450,000 would keep £2,840.00 by avoiding the withdrawal charge (which can include bonus and growth).

Why this charge applies
Agreed price £465,000.00 less separately purchased fixtures and fittings £0.00.
Jess: The counted price is over the £450,000 cap. Getting the counted price down £15,000.00 to £450,000 would keep £2,840.00 by avoiding the withdrawal charge (which can include bonus and growth).
Only genuine fixtures and fittings bought separately under the contract can be excluded — your conveyancer decides; never inflate them.
The cap is £450,000 for the full home, including a shared-ownership purchase. Exactly £450,000 is within the cap.
A 20% charge removes the bonus and its share of growth when the whole balance has received the full bonus. Investment losses or payments without a bonus can mean losing some of your own money. A 25% charge on £5,000 (£4,000 paid in plus £1,000 bonus) leaves £3,750.

What to do and when
Confirm the counted price with your conveyancer
Agreed price £465,000.00 less separately purchased fixtures and fittings £0.00. Only genuine fixtures and fittings bought separately under the contract can be excluded — your conveyancer decides; never inflate them.
Tell your conveyancer you'll use a Lifetime ISA
Complete an investor declaration for each holder and ask for the conveyancer declaration. Money goes to the conveyancer, never to you. Ask your provider how long it needs once it has both declarations.
Request the withdrawal within the 90-day window
Plan for the money to leave the LISA no earlier than 17 Oct 2026 for expected completion on 15 Jan 2027. Arrange this in advance: the date you ask your provider or conveyancer is not the withdrawal date. Providers can take a few days to a few weeks after you ask. The withdrawal date is when money leaves the LISA; it must meet the 12-month rule and determines the 20%/25% date rule. Completion is when the purchase finishes. Aim to request by 16 Dec 2026.
Jess: if completion slips, ask for an extension
Based on money leaving the LISA (withdrawal date) 30 Oct 2026: initial 90-day deadline 28 Jan 2027. Your conveyancer can ask for 60 more days to 29 Mar 2027, then a further 30 to 28 Apr 2027 (180 days maximum). Use the actual receipt date to confirm deadlines. If the purchase fails or the final deadline passes, return all funds, including any charge taken, to the LISA. If £4,000 is not returned, HMRC's retrospective charge is £1,333.33, not £1,000.
After buying, your Lifetime ISA can stay open
You can save up to £4,000 a year and receive a 25% bonus until 50. Withdrawals are charge-free at 60. Check annual ISA allowances and your provider terms.
First Time Buyer ISA planned from 6 Apr 2029
For new savers: it can be used alongside a Lifetime ISA for the same purchase. Transfers from a Lifetime ISA are not permitted. Announced plans still need legislation and provider implementation.

Value at 60: £44,284.85. Extra interest: £7,582.77. Monthly repayment: £63.14.
Illustration, not a recommendation: 29 whole years of 4% annual growth; no new payments. Extra borrowing £11,360.00 at 4.5% over 25 years. Rates and returns can change. For a partial withdrawal this compares keeping the entire balance with borrowing the planned net withdrawal.

Rules as at 29 Oct 2026, based on the supplied HMRC and GOV.UK guidance and Budget sources.
The withdrawal date is the day money leaves the Lifetime ISA, not the day you ask your provider or conveyancer, and not completion. The 12-month rule and the 20%/25% date rule use the withdrawal date. Providers can take a few days to a few weeks after you ask. Confirm provider-specific deadlines and completion separately.
Growth and mortgage figures are illustrations, not forecasts or recommendations. Growth can be negative; future borrowing rates may change.
Educational tool, not financial advice.
The same Lifetime ISA rules apply UK-wide, including Scotland, Wales and Northern Ireland.
Own money lost compares total paid in with this withdrawal’s net amount. For a partial withdrawal it does not account for money remaining in the account. Bonus lost reports the entered bonus received when a charge applies; it is not a precise split of growth or partial withdrawals.
A failed purchase with all funds returned restores the full withdrawal and any charge taken to the Lifetime ISA; no deposit is funded.
