How to Remortgage to Repay Your Help to Buy Equity Loan

Why Remortgaging is the Most Common Choice

When the five-year interest-free window on your Help to Buy (HTB) equity loan comes to a close, you are confronted with one of the most significant financial decisions you will make as a homeowner. Should you continue paying the government's escalating interest fees and watch 20% of your property's future appreciation drain away? Or should you bite the bullet, remortgage, and buy the government out entirely?

For the vast majority of homeowners who do not have a large sum of cash sitting unused in savings, remortgaging to repay is the go-to solution. The mechanics are straightforward: you take out a new, larger mortgage—big enough to cover your existing mortgage balance plus the current value of the Help to Buy loan—and you pay the government off in one clean transaction on completion day.

The result? You own 100% of your home's equity. The government's beneficial interest in your property is gone. From that point, every pound of capital growth that your home generates goes straight into your pocket, not theirs.

Before You Start: Know Your Numbers

The first rule of any remortgage is to know exactly what you are dealing with. Grab a pen and a copy of your most recent mortgage statement and work through these figures.

1. Estimate Your Current Property Value

Unlike a standard loan, the amount you owe on a Help to Buy equity loan is not fixed in cash terms. You borrowed a percentage of your home's value, and you owe that same percentage of its current value. If you took 20% on a £250,000 home, and your home is now worth £310,000, you do not owe £50,000. You owe £62,000.

This is why property growth is such a powerful argument for acting quickly. Every year your home appreciates, your HTB debt grows with it.

To get a working estimate, look at sold prices (not asking prices) on the Land Registry or on property portals for comparable homes on your street or estate. Sold prices reflect reality; asking prices do not.

2. Check Your Affordability

To remortgage and absorb the equity loan, your new mortgage will be larger than your current one. Lenders will assess whether your household income supports the increased borrowing. As a rough guide, most lenders apply a mortgage multiplier of 4x to 4.5x your gross annual household income.

For example, if your existing mortgage balance is £160,000 and you need to borrow an extra £62,000 to pay off the HTB loan, you need a new mortgage of £222,000. To qualify at a 4.5x multiplier, you would need a combined household income of roughly £49,333 per year.

Our BuyBack HTB Calculator models this affordability threshold for every future year, so you can plan the optimal window to remortgage before your income or property value shifts.

3. Calculate Your New LTV

Loan-to-Value (LTV) is the ratio of your mortgage to your property's value, expressed as a percentage. LTV brackets directly determine what interest rate you will be offered. Typically, the lower the LTV, the better the rate.

To calculate your new LTV: divide your new total mortgage amount (existing balance + HTB buyout) by your property value, and multiply by 100.

For example: (£222,000 ÷ £310,000) × 100 = 71.6% LTV. This would fall comfortably into the 75% LTV band, where many lenders offer their most competitive rates.

Step 1: Speak to a Whole-of-Market Mortgage Broker

Before instructing anyone else or paying for anything, your first call should be to an independent, whole-of-market mortgage broker. This is non-negotiable.

A broker who has access to the entire market—rather than a tied adviser who can only recommend products from one lender—will search hundreds of mortgage products on your behalf. They understand the nuances of lenders' policies on Help to Buy redemptions, LTV thresholds, and affordability calculations. Most importantly, they can give you a realistic assessment of whether you qualify before you spend any money.

The broker conversation will typically shape the timing of your RICS valuation. Do not commission a valuation before you know you have a viable mortgage option, as valuations have a strict three-month validity window.

Step 2: Commission Your RICS Valuation

This is the most bureaucratically sensitive step in the entire process and the one that catches most people out. To formally redeem your Help to Buy equity loan, the government must be paid a precise pound amount. That amount is determined by an independent assessment of your home's current market value, carried out by a surveyor registered with the Royal Institution of Chartered Surveyors (RICS).

An estate agent's valuation, an automated online estimate, or even a bank's mortgage survey is completely inadmissible. It must be a full RICS inspection, completed in person, with the surveyor's RICS credentials on the report.

Because mortgage applications, legal work, and Lenvi's own processing times can easily consume two to three months in total, the timing of your RICS valuation is critical. Commission it only once your mortgage application has been submitted and you have a realistic completion timeline from your solicitor.

Step 3: Apply for Your New Mortgage

Your broker will submit your full mortgage application to the lender with the best product for your circumstances. The application purpose will be noted as a remortgage for the purpose of Help to Buy redemption. The lender will carry out their standard checks: a credit search, an affordability assessment, and their own property valuation (which may be a desktop valuation or a physical survey).

If your application is approved, the lender will issue a formal Mortgage Offer. This is the green light. Keep your solicitor informed, as conveyancing can now proceed in earnest.

Step 4: Instruct an Experienced Solicitor

You must appoint a solicitor or licensed conveyancer to handle the legal transfer of funds and to remove the government's legal charge from your property title. This charge, held by Homes England via the Land Registry, cannot be removed without a solicitor's involvement.

This is not a task to hand to a generalist solicitor. Help to Buy redemptions require specific administrative knowledge. The paperwork requirements imposed by Lenvi are exacting, and a solicitor unfamiliar with the process can introduce delays that cause your RICS valuation to expire. Ask your solicitor directly: "How many Help to Buy redemptions have you completed in the last year?"

Step 5: Submit Your Redemption Application to Lenvi

Lenvi is the scheme administrator that manages Help to Buy loans on behalf of Homes England. Either you or your solicitor must formally notify Lenvi of your intention to redeem.

To submit, you will need:

• A completed Redemption Application Form (available from the Lenvi portal).
• A physical copy of your RICS valuation report.
• A non-refundable administration fee of £200.

Lenvi will review the submission. If the valuation is accepted, they will process your application and issue the most important document in this entire process.

Step 6: Receive Your Authority to Proceed

The Authority to Proceed (ATP) is Lenvi's formal confirmation of the exact cash amount you must pay to clear your equity loan. This figure is calculated as the equity loan percentage (e.g., 20%) applied to the RICS surveyor's stated value—or the sale price, if you are selling, whichever is higher.

Your solicitor will use this figure to arrange the completion finances. They will request their own equivalent document, called a Redemption Statement, which will state the total sum required, including the daily interest amount accruing while the process wraps up.

Step 7: Completion Day

On the agreed completion date, your solicitor acts as the financial co-ordinator. The sequence of transfers happens simultaneously and in strict order:

1. Your new lender releases the mortgage funds (e.g., £222,000) to your solicitor's client account.
2. Your solicitor redeems and closes your old mortgage, repaying the existing lender (e.g., £160,000 + any early repayment charges or redemption fees).
3. Your solicitor wires the precise ATP amount (e.g., £62,000) directly to Homes England via Lenvi.
4. Any remaining cash balance (your legal and broker fees, Land Registry fees, and any surplus) is settled.

Within approximately six to eight weeks of completion, Lenvi notifies the Land Registry, and the government's beneficial interest charge is formally removed from your property title. Your home is now 100% yours.

What are the Costs?

Here are the typical costs to budget for when remortgaging to repay a Help to Buy loan:

• RICS Valuation: £300–£600 (depending on property size and surveyor).
• Lenvi Redemption Administration Fee: £200 (non-refundable).
• Mortgage Broker Fee: £0–£500 (many whole-of-market brokers earn a commission from lenders; always clarify upfront).
• Solicitor / Conveyancer Fees: £800–£1,500 (plus VAT and disbursements).
• Mortgage Early Repayment Charge (ERC): Varies widely. If you are currently within a fixed-rate deal, your existing lender will typically charge a percentage (e.g., 1%–5%) of the amount you are repaying early. Check your current mortgage Terms & Conditions before starting the process.
• Land Registry Fee: £20–£125.

Modelling the Financial Case

Whether remortgaging makes sense for you depends entirely on your specific numbers: your property's current value, your outstanding mortgage balance, the HTB loan percentage, the mortgage rates available to you, and your income. Generic advice is not enough when tens of thousands of pounds are at stake.

Our BuyBack HTB Calculator models your exact situation over up to 40 years, projecting the total cost of keeping the equity loan versus the cost of buying it out at any given point. It calculates your property's shadow cost, the escalating interest trajectory, the crossover point, and the minimum household income you need to qualify for the larger mortgage at each future date.

Run your numbers before you call anyone. Know the math before the broker tells you what you can afford.
