Yes, remortgaging a shared ownership home may be possible without buying another share. However, it can work differently from remortgaging a property you own outright. Your lease, housing association or other landlord, the lender’s shared ownership criteria and the mortgage balance all need to be considered.
If your fixed-rate deal is ending, the important question is not simply whether a cheaper rate exists. It is whether switching your product or lender offers a worthwhile result once the approval process, fees and your ongoing rent and service charges are taken into account.
Can I remortgage a shared ownership property?
Potentially, yes. If you own, for example, a 40% share in a home and pay rent on the remaining 60%, you may be able to replace the mortgage secured against your share without buying any additional equity.
Not every lender offers shared ownership remortgages, and some have particular requirements for the minimum share owned, the lease, affordability or the property itself. The exact options depend on your circumstances.
Do I have to staircase when I remortgage?
No, not necessarily. Remortgaging and staircasing are two different actions. A remortgage replaces your mortgage with another mortgage, usually from a new lender. Staircasing means purchasing an additional share of the property from the landlord.
You might choose to do both together, but you do not have to assume that purchasing more equity is required just because your existing deal is ending.
Where you do staircase, the additional share is normally priced using the property’s value at the time, subject to the terms of the lease. The government’s shared ownership staircasing guidance explains why the permitted share increments can differ between older and newer schemes.
Is switching to a new rate with my current lender simpler?
It may be. A product transfer means changing the mortgage product with your existing lender, rather than moving the debt to a new lender. Depending on the lender and whether you want to borrow more, the process may be more straightforward than a full remortgage.
But the cheapest-looking rate is not always the best overall outcome. Compare the product fee, early repayment charge, total cost over the relevant period and whether a different lender may provide a more suitable option.
Will I need permission from my housing association?
Often, yes when changing lender or increasing borrowing. Shared ownership leases can require the landlord’s written consent to mortgage terms. Requirements for an existing-lender product transfer with no extra borrowing may be different.
Homes England’s guidance for lenders, landlords and conveyancers, published 31 July 2026, explains the role of consent and the mortgage protection clause in shared ownership arrangements.
Ask your housing association or landlord what their process is before committing to a new mortgage. Your conveyancer may also need to obtain written approval and check the lease requirements.
How does a lender assess the property and my share?
The lender needs to assess the value and mortgageability of the share you own. For example, owning 40% of a home valued at £300,000 gives a share value of £120,000 before taking account of any outstanding mortgage. That is not the same as having £300,000 of equity available to secure a loan.
Your current loan balance, the lender’s valuation, property type, lease terms and remaining lease length may affect the options.
Will the lender include my rent and service charge?
These ongoing costs matter. Shared ownership buyers normally pay a mortgage on the share they own and rent on the share retained by the landlord. Service charges, management costs and other leasehold payments may also apply.
A new lender will assess affordability using your income, financial commitments and relevant ongoing housing costs. An attractive mortgage payment on its own is not enough if the combined monthly cost is not sustainable.
Can I borrow extra money when I remortgage?
Possibly, but extra borrowing can be significantly more restricted than a simple remortgage.
Homes England’s guidance explains that borrowing secured against the shared owner’s interest is subject to the lease and mortgage protection arrangements; landlord approval can be relevant, especially for further advances. The lender will also assess the purpose of the borrowing and affordability.
For that reason, disclose at the beginning whether you only want a new rate, hope to buy additional shares, or want to release additional funds. These are different cases and should not be treated as interchangeable.
What fees and restrictions should I check?
- Early repayment charges on your existing mortgage and the date your current deal ends.
- The new lender’s arrangement, valuation and legal fees.
- Any housing association administration or consent charges.
- Whether you are also staircasing, which can involve valuation and legal work.
- Remaining lease length, lease terms and property issues that can limit lenders.
- The combined future cost of mortgage payments, rent and service charges.
Do not assume that a lower headline interest rate will produce a lower overall cost.
What if I want to staircase at the same time?
This can be worth exploring if you want to own more of the home, but it changes the amount you need to finance and can trigger additional valuation, legal and landlord steps. In return, your rent on the unowned share may reduce.
Check the permitted staircasing amounts in your lease. Newer schemes may allow smaller increments than older ones. If you are considering this route, compare what you would pay today with the likely ongoing mortgage, rent and service-charge position after the extra share is purchased.
What information should I have ready?
A useful first review usually starts with your current mortgage balance, lender and fixed-rate end date; the percentage share you own; the full property’s approximate value; the latest rent and service-charge statements; lease details; and your current income and commitments. If you have the housing association’s remortgaging guidance or consent form, include that too.
