How does the Help to Buy scheme work?
26th March 2026
By Simon Carr
TL;DR: The Help to Buy Equity Loan scheme provided first-time buyers and existing homeowners with a government loan, typically 20% (or 40% in London), to purchase a new-build home with a smaller mortgage and a 5% deposit. While the main scheme in England is now closed to new applications, understanding how the Help to Buy Equity Loan works is crucial for those managing an existing loan or looking for similar schemes.
The Help to Buy scheme was one of the UK Government’s key initiatives aimed at making new-build homes more affordable for buyers struggling to save large deposits. The most popular element of this programme was the Help to Buy Equity Loan, which ran successfully for many years before closing to new applications in England in March 2023 (and earlier regional variants). If you own a property purchased through this scheme, understanding its mechanics—especially the repayment requirements—is essential for your long-term financial planning.
Understanding How Does the Help to Buy Scheme Work?
The core concept of the Help to Buy Equity Loan was simple: the government would loan you a significant portion of the property’s purchase price interest-free for the first five years. This arrangement meant that buyers required a lower loan-to-value (LTV) mortgage from a traditional lender, making the monthly mortgage payments potentially more accessible.
It is important to note upfront that while this article explains the mechanics of the now-closed Equity Loan scheme, you cannot apply for a new loan under this specific programme. If you are looking for current government assistance, you should explore options like the Lifetime ISA (LISA) or shared ownership schemes.
Key Features of the Help to Buy Equity Loan
The Equity Loan scheme operated on a specific funding structure, applicable only to new-build properties sold by registered builders.
The Financial Structure
- Your Deposit: You needed a minimum of 5% of the property purchase price.
- The Government Loan (Equity Loan): The government loaned you up to 20% of the purchase price, or up to 40% if the property was located in London.
- Your Mortgage: You secured a conventional mortgage for the remaining 75% (or 55% in London).
Crucially, the government’s stake was an equity loan, meaning the amount owed was not fixed but was tied to the value of the property. If the property increased in value, the monetary amount you owed the government increased too. Conversely, if the property value dropped, the amount owed decreased.
Eligibility and Limitations (When the Scheme was Open)
While the scheme operated, it was subject to strict rules:
- It was only available for purchasing new-build homes.
- The property had to be your sole residence, meaning you could not use the scheme to buy a second home or a buy-to-let investment.
- There were regional price caps on the maximum value of the property you could purchase.
Managing and Repaying the Equity Loan
For existing loan holders, understanding the repayment schedule and process is critical. The loan needs to be repaid in full either when you sell the property, pay off your mortgage, or reach the end of the loan term (usually 25 years), whichever comes first.
The Interest-Free Period
The first five years of the Equity Loan were interest-free. However, after the fifth anniversary of the purchase, interest fees begin to apply. This interest is commonly referred to as the “management fee” or “loan administration fee.”
- Year 6 Onwards: Interest starts at 1.75% of the loan amount.
- Annual Rises: This interest rate increases each year by the Consumer Price Index (CPI) plus 2%.
Note that these interest payments only cover the interest; they do not reduce the principal amount of the loan. To reduce the principal, you must make scheduled payments through a process called staircasing.
The Staircasing Process (Partial Repayments)
Staircasing involves making voluntary partial repayments of the Equity Loan. These payments must be at least 10% of the property’s current market value at the time of repayment.
Because the loan is based on a percentage of the property’s value, you must obtain an independent valuation from a Royal Institution of Chartered Surveyors (RICS) surveyor before staircasing.
Example of Staircasing:
- You bought a property for £200,000 with a 20% (£40,000) equity loan.
- Five years later, the property is valued at £250,000.
- Your 20% Equity Loan is now worth £50,000 (20% of £250,000).
- If you wish to repay 10% (the minimum), you must repay £25,000 (10% of £250,000), reducing the government’s stake to 10% of the property’s value.
This illustrates why the market valuation is so crucial—the amount you repay is determined by the property’s current value, not its original purchase price.
What Happens When You Sell a Help to Buy Property?
If you decide to sell your property before fully repaying the Equity Loan, the government is entitled to receive its percentage share of the final sale price. The process is managed by an independent solicitor and the relevant Help to Buy agent (e.g., Homes England in England).
As with staircasing, a valuation is usually required to determine the government’s share shortly before the sale completes. After paying off your mortgage and all associated fees (including any outstanding interest on the equity loan), the percentage owed to the government is deducted from the sale proceeds.
For comprehensive guidance on managing an existing loan or the formal sales process, you should consult the official government resources provided by the relevant authority, such as Homes England. You can find detailed scheme guidance and administration details on the Homes England website.
Alternatives to the Closed Help to Buy Scheme
Since the Equity Loan scheme is closed, many buyers now seek alternative avenues to help them afford a property:
- Shared Ownership: This allows you to buy a share of a property (usually 25% to 75%) and pay rent on the remaining share. You can increase your ownership share over time (staircasing).
- Lifetime ISA (LISA): This is a savings product where the government adds a 25% bonus to your savings (up to £1,000 per year) towards your first home or retirement.
- Guarantor Mortgages: These allow family members to use their property or savings as security for your mortgage, potentially allowing you to borrow more or access better rates with a smaller deposit.
- Deposit Boost Schemes: Some lenders offer schemes designed to help first-time buyers with smaller deposits, though these come with specific criteria and may involve slightly higher interest rates.
When considering any complex mortgage or loan product, especially those involving external support or equity shares, always seek independent financial advice tailored to your personal circumstances.
People also asked
How long do I have to repay the Help to Buy loan?
The Equity Loan must be repaid in full either when you sell the property, when you pay off your main mortgage, or at the end of the loan term, which is typically 25 years from the purchase date, whichever event happens earliest.
Do I have to pay interest on the Help to Buy loan?
Yes, you must start paying interest (an administrative fee) from the sixth year of ownership. This fee starts at 1.75% and increases annually based on inflation (CPI) plus 2%, but these payments do not reduce the principal amount owed.
Can I make partial repayments (staircasing)?
Yes, you can make voluntary partial repayments, known as staircasing. However, these payments must be at least 10% of the property’s current market value, which requires an official RICS valuation before the payment can be processed.
What happens if my property value goes down?
If the value of your property decreases, the amount you owe on the Equity Loan also decreases, as the loan is tied to a percentage of the current market value. Conversely, if the value increases, the amount you owe increases too.
Is the Help to Buy ISA still available?
No, the Help to Buy ISA scheme is also closed to new accounts. It was replaced primarily by the Lifetime ISA (LISA), which offers a similar government bonus but allows for higher annual contributions and maximum property values.
The Help to Buy Equity Loan scheme was a significant factor in helping thousands of UK residents step onto the property ladder. If you currently hold a loan, proactive management, particularly planning for the interest payments that commence after five years and understanding the staircasing process, will ensure you manage your equity effectively.
