No, you cannot use Help to Buy twice. Every Help to Buy scheme in the UK — the Help to Buy: ISA, the Lifetime ISA, and the now-closed Help to Buy: Equity Loan — is restricted to first-time buyers, and that status disappears permanently the moment you complete a residential property purchase. If you have already bought a home using any of these schemes, or bought one without them, you cannot claim a government bonus or equity loan on a second purchase.
The rule is not about which scheme you used or whether you claimed the bonus at all. It is about whether you have ever owned residential property. Sell the home you bought with a Help to Buy: ISA five years ago, and you still cannot use a Lifetime ISA bonus on your next place. The door closes once and stays closed.
Why First-Time Buyer Status Is the Gatekeeper
The statutory definition sits in Schedule 6ZA of the Finance Act 2003, introduced by the Finance Act 2017. To qualify, you must never have been a purchaser of a major interest in a dwelling, and you must never have acquired an equivalent interest in a dwelling located anywhere outside England, Wales, and Northern Ireland.1Legislation.gov.uk. Finance Act 2003 Schedule 6ZA HMRC guidance confirms that this includes property acquired through inheritance, as a gift, or through an alternative finance arrangement.2HM Revenue & Customs. SDLTM29845 – Definition of a First-Time Buyer FA03/SCH6ZA/PARA6
Even a partial share in a dwelling counts. If you held a 10% stake in a flat with family, or you inherited a cottage abroad you never lived in, you are no longer a first-time buyer. The one narrow exception involves leases: acquiring the grant or assignment of a lease with fewer than 21 years remaining does not count against you.2HM Revenue & Customs. SDLTM29845 – Definition of a First-Time Buyer FA03/SCH6ZA/PARA6
Commercial and mixed-use property does not automatically disqualify you, provided that property did not include a dwelling. Someone who owns a warehouse or a shop without any residential element can still qualify. But the moment any residential interest enters the picture, the designation is gone for good.2HM Revenue & Customs. SDLTM29845 – Definition of a First-Time Buyer FA03/SCH6ZA/PARA6
What Happens to Your Help to Buy: ISA After You’ve Bought
The Help to Buy: ISA closed to new accounts several years ago. Existing account holders can keep saving and claim the 25% government bonus, worth up to £3,000, until November 2030.3GOV.UK. Help to Buy ISA But the bonus is a one-shot benefit tied to your first property purchase. Once you have used it, or bought a home without using it, the account cannot deliver a second bonus for a later purchase.
If you still hold a Help to Buy: ISA and have not yet bought, that November 2030 date is the hard cutoff. After it, the bonus becomes unclaimed and lost.
Can You Use a Lifetime ISA for a Second Home?
This is where the “use it twice” question comes up most often. People who opened a Lifetime ISA years ago sometimes wonder if they can use it for a second property later. The answer is no. The Lifetime ISA property bonus is a one-time benefit tied to your first-time buyer status.
The account itself does not have to close. You can keep contributing up to £4,000 a year and keep receiving the 25% bonus of up to £1,000 annually.4GOV.UK. Lifetime ISA Overview What changes is what you can do with the money. After you have bought your first home, you can only withdraw penalty-free from age 60 onwards, for retirement. Take the money out for any other reason — including a second home purchase — and you face a 25% withdrawal charge that claws back the bonus and takes a slice of your own savings on top.5GOV.UK. Withdrawing Money From Your Lifetime ISA
The Help to Buy: Equity Loan is not a route either. It closed to new applications on 31 October 2022, with all legal completions required by 31 March 2023, and there is no replacement programme with the same structure.6GOV.UK. Help to Buy Applications Closure Marketing Guidance
Buying Jointly With a Previous Homeowner
If you are the first-time buyer and your partner has owned before, the picture splits depending on which benefit you are looking at.
For the Lifetime ISA, eligibility is assessed individually. You can still claim your own Lifetime ISA bonus even if the person buying with you has owned property before.7HM Revenue & Customs. Conveyancers Lifetime ISA Technical Guidance – Section: Joint Ownership They cannot claim a bonus of their own, but yours goes through.
Stamp Duty Land Tax relief is stricter. Every purchaser named on the transaction must qualify as a first-time buyer. If one person on the deed has owned before, neither buyer gets the relief.8GOV.UK. Stamp Duty Land Tax Relief for Land or Property Transactions Couples in this situation often find the Lifetime ISA bonus is preserved while thousands in potential stamp duty savings are not.
One workaround is for only the first-time buyer to purchase in their sole name. That preserves both the bonus and the SDLT relief, but it has real consequences for the other partner’s legal rights in the property, mortgage affordability, and future tax exposure. Do not do it without legal advice.
If Your Purchase Falls Through
A collapsed sale does not cost you your first-time buyer status. The legal definition only changes once the transfer of title actually completes and is registered. If a sale falls apart before exchange of contracts, or even after exchange but before legal completion, you remain a first-time buyer and can use your Help to Buy: ISA or Lifetime ISA bonus on a different property.
If your conveyancer already requested the Lifetime ISA bonus from your provider but the purchase did not complete within 90 days, the funds must be returned. Your conveyancer submits a declaration confirming the purchase was not completed, and the bonus goes back into your Lifetime ISA account.9GOV.UK. Conveyancers First Time Residential Purchase With a Lifetime ISA Once the return is processed, you can try again on a different property. Keep records of the failed transaction. Your next conveyancer and mortgage lender will want to see them.
Routes Still Open if You’ve Already Owned
Losing first-time buyer status does not shut every door. Two government-backed routes are worth knowing about.
Shared Ownership does not require you to be a first-time buyer. You must not currently own another home, but if you previously owned and have since sold, you can qualify. Your household income must be no more than £80,000 a year, or £90,000 in London. Shared Ownership lets you buy a share of a property, typically between 25% and 75%, and pay rent on the remainder, with the option to increase your share over time. It has its own complexities around staircasing, service charges, and resale restrictions, but it is open to people the ISA schemes have already served.
First Homes is the other government scheme, but it will not help a repeat buyer. Properties are sold at a discount of 30% to 50% below market value, subject to the same £80,000 (£90,000 in London) income caps, and every buyer on a joint application must be a first-time purchaser.10GOV.UK. First Homes Scheme First-Time Buyers Guide Overview If you have owned a home before, this route is closed to you as well.
