Can you remortgage a Help to Buy property?

If you bought your home using the Help to Buy: Equity Loan, you may be approaching the point where your initial mortgage deal ends or you’re considering switching to a new mortgage term. In many cases, remortgaging is possible, but it’s not exactly the same as remortgaging a standard property.

This guide explains what typically matters when remortgaging a Help to Buy property—how lenders may view the remaining equity loan, what you may need to do with the Help to Buy loan itself, and the permissions and costs that can affect your timeline.

Why people remortgage a Help to Buy home

Common reasons include:

Your current mortgage deal is ending and you want to move onto a new fixed or more suitable product.
You want more flexibility (for example, a different term length or repayment structure).
You want to repay the Help to Buy equity loan as part of your long-term plan.
Your property value has increased, and you want to use built-up equity to reduce the remaining loan or improve affordability.

Can you remortgage if you still have a Help to Buy equity loan?

In many cases, yes—you can remortgage even if you still have an outstanding Help to Buy equity loan.

However, lenders will usually assess the remortgage as a whole affordability and risk decision. That means they may consider:

Your income and outgoings and whether you can afford the new mortgage repayments.
The total debt picture, including the fact that the Help to Buy equity loan remains in place.
How the remortgage amount and loan-to-value (LTV) affects the product you can access.

Because Help to Buy properties can involve additional steps and constraints, it’s often helpful to take a structured approach to comparing options rather than assuming the same routes you used for your original mortgage will apply.

Do you have to repay the Help to Buy loan when you remortgage?

Not necessarily.

In practice, there are two broad scenarios:

You remortgage without repaying the Help to Buy equity loan immediately. In this case, the Help to Buy loan remains outstanding after the remortgage.
You remortgage to repay some or all of the Help to Buy equity loan. This may involve using part of the new mortgage and/or other funds to reduce the equity loan balance.

Even when you don’t repay the equity loan straight away, it’s important to understand that the Help to Buy loan has to be dealt with when you sell the property. Planning ahead can help you avoid being forced into a rushed solution later.

Affordability: what lenders typically look at

When you remortgage, a lender will generally focus on whether you can afford the proposed mortgage payments. With a Help to Buy property, the assessment may also take account of the additional financial obligation created by the remaining equity loan.

If your circumstances have changed since you took out your original mortgage—such as reduced income, increased debts, or a different employment situation—your options may narrow. That doesn’t always mean remortgaging is off the table, but it can affect which lenders and product types are realistic.

Remortgaging to repay the Help to Buy equity loan

If you’re aiming to reduce or clear the equity loan, you’ll want to model the numbers carefully.

Key points to consider:

Repayment is typically based on the property’s current value, not what you paid for it.
You may need to factor in higher mortgage repayments if you borrow more to repay the equity loan.
Extending the mortgage term can reduce monthly payments, but it may increase the total interest paid over the life of the loan.

A clear repayment plan can also help you decide whether it’s better to repay the equity loan in one go or to use a staged approach.

Staircasing: using value to reduce the equity loan

Help to Buy also allows staircasing, which means buying more of the property from the equity loan provider so you reduce the amount you owe.

Common considerations include:

Staircasing is typically done in increments, rather than all at once.
If your home has increased in value, staircasing can help you reduce the equity loan balance using the equity you’ve built up.
Staircasing can affect your overall LTV position, which in turn may influence the mortgage products available to you.

Before choosing a staircasing approach, it’s useful to compare how the remaining equity loan balance changes your remortgage options and affordability.

Do you need permission to remortgage?

If you still have a portion of your Help to Buy equity loan outstanding, you’ll usually need to request a Deed of Postponement.

This is typically handled through your solicitor, who will submit the request to the relevant Help to Buy administrator. It’s worth planning for this because it can affect your timeline—and it’s another reason why remortgaging a Help to Buy property often needs more coordination than a standard remortgage.

Costs to plan for

Remortgaging costs can vary depending on your lender, your solicitor, and the structure of your remortgage. For Help to Buy properties, there are a few items that commonly come up:

Valuation

A valuation is usually required. In some cases, the valuation may also support the calculation of the equity loan repayment amount.

Admin fees related to Help to Buy

The equity loan provider may charge an administration fee when you’re dealing with repayment or staircasing.

Solicitor’s fees

Your solicitor will handle legal work connected to the remortgage and the Deed of Postponement process. Fees can vary based on the complexity of your case.

Early repayment charges (ERCs)

If you’re leaving your current mortgage deal before the end of the fixed period, there may be early repayment charges. These charges depend on your existing mortgage contract and the timing of your switch.

Mortgage broker fees (where applicable)

Some borrowers pay a broker fee, while others may find it’s incorporated into the mortgage arrangement. The key is to understand how any broker fee is structured so you can compare the overall cost of the remortgage.

How to approach lender selection for a Help to Buy remortgage

Because Help to Buy remortgages can involve additional constraints, a practical approach is to:

Start with a clear view of your target outcome (switch deal only, repay part, or repay more via staircasing).
Consider how the remaining equity loan affects LTV and affordability.
Discuss your situation with a broker who can help you identify lenders that are more likely to be able to accommodate the Help to Buy position.

This can help reduce wasted time and avoid pursuing options that may not align with how lenders treat the equity loan.
