The Lifetime ISA (LISA) is the primary government Help to Buy scheme in 2026, offering a 25% bonus (up to £1,000/year) on savings used for a first home up to £450,000. The original Help to Buy Equity Loan scheme closed to new applications in 2023, but existing borrowers must understand repayment rules. Shared Ownership allows you to buy 25–75% of a home and pay rent on the remainder.

LISA Bonus = Annual Contribution (max £4,000) × 25% = Up to £1,000/year government bonus

Buying your first home in the UK is a major financial milestone, and the government offers several schemes to help make it achievable. While the original Help to Buy Equity Loan scheme closed to new applicants in March 2023, the Lifetime ISA continues to provide valuable first-time buyer benefits, and Shared Ownership offers an affordable route to property ownership.

What This Means

Your calculation shows the total savings plus government bonus you can accumulate over your chosen time period using the Lifetime ISA. Remember that LISA funds can only be used for a first home purchase costing £450,000 or less, and the property must be purchased with a mortgage. Withdrawing LISA funds for any other purpose (before age 60) incurs a 25% penalty, which means you lose the government bonus and 6.25% of your own contributions.

Lifetime ISA (LISA): The Primary Help to Buy Scheme in 2026

How the LISA Works

  • Open to anyone aged 18–39
  • Save up to £4,000 per tax year
  • Government adds a 25% bonus: up to £1,000/year
  • Use for a first home (up to £450,000) or retirement (age 60+)
  • Must be open for at least 12 months before you can buy
  • Property must be purchased with a mortgage

2 years£8,000£2,000£510£10,510

4 years£16,000£4,000£2,280£22,280
5 years£20,000£5,000£3,680£28,680

A couple each with a LISA can accumulate £57,360 over 5 years — enough for a 10%+ deposit on properties up to £450,000.

LISA Withdrawal Penalty Warning

If you withdraw LISA funds for anything other than a qualifying first home or retirement, you will lose 25% of the withdrawal amount. On £5,000 (£4,000 savings + £1,000 bonus), the penalty is £1,250 — meaning you get back only £3,750, which is £250 less than you contributed. The penalty effectively confiscates the bonus AND 6.25% of your own money.

Shared Ownership: Buy What You Can Afford

How Shared Ownership Works

You buy a 25–75% share of a property and pay rent on the remaining share to a housing association. Over time, you can "staircase" (buy more shares) until you own 100%.

Shared Ownership Example: £300,000 Property

Share PurchasedMortgage Needed (10% deposit)Monthly MortgageMonthly Rent (2.75%)Total Monthly
25% (£75,000)£67,500£398£516£914
40% (£120,000)£108,000£637£413£1,050
50% (£150,000)£135,000£797£344£1,141
75% (£225,000)£202,500£1,195£172£1,367
100% (£300,000)£270,000£1,593£0£1,593

Mortgage calculated at 5.5% over 25 years. Rent at 2.75% of the unsold share annually.

Shared Ownership Eligibility (2026)

  • Household income must be £80,000 or less (£90,000 in London)
  • Must be a first-time buyer OR a previous homeowner who can't afford to buy now
  • Must not be able to afford a suitable home on the open market
  • Priority given to local residents, key workers, and military

Help to Buy Equity Loan: Repayment Guide for Existing Borrowers

Although the Help to Buy Equity Loan scheme closed to new applicants in 2023, approximately 380,000 households have existing equity loans that must be managed and eventually repaid. Here is what you need to know:

Key Dates and Fees

YearFee on Equity LoanNotes
Years 1–5Interest-freeOnly a £1/month management fee
Year 61.75%Interest charges begin
Year 7+1.75% + RPI + 1%Increases annually with inflation

Critical: The equity loan is a percentage of your home's current value, NOT the original amount. If you took a 20% equity loan on a £300,000 home (£60,000), and the home is now worth £400,000, you owe 20% of £400,000 = £80,000.

Repayment Options

  1. Remortgage to pay off: Take a larger mortgage to repay the equity loan. Best done before year 6 when interest charges start.
  2. Sell the property: The equity loan percentage is deducted from sale proceeds.
  3. Part repayment: You can pay off 10%+ of the current property value at any time (minimum £1,000 per repayment).
  4. Continue paying: Keep the loan and pay the annual interest charges, which increase each year.

First Homes Scheme: 30–50% Discount on New Builds

The First Homes scheme offers 30–50% discounts on selected new-build properties. The discount is passed on to future first-time buyers when you sell.

Eligibility

  • First-time buyer (never owned a home)
  • Household income under £80,000 (£90,000 in London)
  • Property price must be £250,000 or less after discount (£420,000 in London)
  • Must use a mortgage for at least 50% of the discounted price
  • Must be your primary residence

First Homes Example

Market ValueDiscount (30%)Your PriceDeposit (10%)Mortgage Needed
£300,000-£90,000£210,000£21,000£189,000
£350,000-£105,000£245,000£24,500£220,500

Key restriction: When you sell a First Home, you must sell at the same percentage discount below market value. This means the discount benefits future buyers too, but limits your capital gain compared to buying on the open market.

Frequently Asked Questions

Is Help to Buy still available in 2026?

The original Help to Buy Equity Loan scheme closed to new applications in March 2023. However, the Lifetime ISA (LISA) remains active and provides a 25% government bonus on savings for first-time buyers. Shared Ownership and the First Homes scheme are also active alternatives. Existing Help to Buy Equity Loan borrowers continue under the original terms and should plan for repayment or remortgage before year 6 interest charges begin.

What is the maximum Lifetime ISA bonus?

You can save up to £4,000 per tax year into a LISA and receive a 25% government bonus of up to £1,000 per year. Over 5 years, that is £5,000 in free government money on £20,000 of savings. A couple both using LISAs doubles this to £10,000 bonus on £40,000 saved. The LISA can be used to buy a first home costing up to £450,000, or held until age 60 for retirement.

Can I use a Lifetime ISA and Shared Ownership together?

Yes. You can use your LISA savings as the deposit for a Shared Ownership purchase, as long as the total property value is £450,000 or less (not just your share). This combination is powerful: save £28,680 over 5 years in a LISA (including bonus), use it as a deposit on a 25–40% share of a property, and keep monthly costs lower than buying outright.

What happens if I withdraw LISA money for something other than a first home?

You will incur a 25% withdrawal penalty. This sounds like you just lose the bonus, but it is actually worse: on £5,000 (£4,000 you saved + £1,000 bonus), the penalty is 25% of £5,000 = £1,250. You receive only £3,750 — which is £250 less than you put in. The government temporarily reduced this to 20% during the pandemic but it has returned to 25%. The penalty does not apply after age 60 or for terminal illness.

How does Shared Ownership staircasing work?

Staircasing means buying additional shares of your Shared Ownership property. You can staircase in increments (typically 10%+ at a time) by getting a new valuation and remortgaging. The cost is based on the property's current value, so if values have risen, you pay more per additional share. Once you reach 100%, you own the property outright and no longer pay rent on the remaining share. Most housing associations charge £150–£300 for a staircasing valuation, plus legal fees of £500–£1,000.

Should I repay my Help to Buy Equity Loan before year 6?

Generally yes, if you can afford to. The loan is interest-free for the first 5 years, but from year 6 you pay 1.75% (rising annually at RPI + 1%). On a £60,000 loan, that is £1,050 in year 6, increasing each year. By year 10, with 4% inflation, you could be paying £1,500+/year. Remortgage to pay off the equity loan before year 6 if possible. If your home has appreciated, the loan amount (as a percentage of current value) will be larger than the original amount borrowed.
