Shared Ownership Remortgage (2026): Your Options & Staircasing
Yes, you can remortgage a shared ownership home — whether to grab a better rate or to buy a bigger share (“staircasing”). But the lender pool is smaller and the valuation timing catches people out. Here’s how it works, and the one trap that derails more staircasing remortgages than any other.

Quick answer
Yes, you can remortgage a shared ownership property, and there are two main reasons to do it: to switch to a better mortgage deal when your current one ends (avoiding your lender’s standard variable rate), or to “staircase” — borrow more to buy a bigger share of your home. Both are common and entirely doable, but shared ownership remortgages have specific features. Fewer lenders offer shared ownership mortgages than standard ones, so your choice is more limited (though the list is healthy and includes major names), and the process involves your housing association and lease, not just the lender. If you’re staircasing, the extra share is priced at the property’s current market value — set by an independent RICS “Red Book” valuation — not what you originally paid, so in a rising market the extra share costs more. Crucially, that valuation is usually only valid for three months, and a remortgage that takes longer than that to complete can force a fresh (and possibly higher) valuation — the single most common way staircasing goes wrong. The big prize is reaching 100% ownership: at that point you own the property outright, pay no rent, escape most shared ownership restrictions, and can access the full standard mortgage market rather than the smaller shared ownership pool. Because the lender criteria, lease terms and valuation timing all interact, a broker who knows shared ownership is especially valuable here. This is general information, not advice.

Can you remortgage shared ownership?
Yes — remortgaging a shared ownership home is entirely possible and very common, but it works a little differently from a standard remortgage. The key difference is that not every lender offers shared ownership mortgages. Because shared ownership involves a lease with a housing association and a part-owned property, it’s a more specialist product, so the pool of lenders is smaller than for standard mortgages. The good news is that the list is healthy and includes major high-street names and building societies — but it does mean your options are more limited, and it’s easy to miss the best deal if you only look at your current lender or the mainstream market. A second point: since you first bought, lender criteria may have changed, and so may your own circumstances (income, credit, the property’s value). All of this gets reassessed at remortgage. The practical upshot is that shared ownership remortgaging is genuinely achievable, but matching to a lender that both offers shared ownership and suits your situation is where the value lies — which is exactly what a specialist broker does. If you originally bought through the scheme, our guides to the shared ownership mortgage and first-time buyer schemes cover how the purchase side works.
The two reasons to remortgage
Rate switch vs staircasing — often done together
Shared ownership owners remortgage for two main reasons, and sometimes both at once:
1. To get a better rate. Just like any homeowner, when your initial fixed or tracker deal ends, you’d otherwise roll onto your lender’s standard variable rate (SVR), which is usually more expensive. Remortgaging to a new deal — with your current lender (a product transfer) or a new one — avoids that. This is the simplest reason and works much like a standard remortgage, just within the shared ownership lender pool. Our guide on when to remortgage applies here too.
2. To staircase (buy a bigger share). This is the reason unique to shared ownership. “Staircasing” means buying additional shares in your home to increase your ownership percentage — say from 40% to 60%, or all the way to 100%. Unless you have savings to cover it, buying more shares usually means borrowing more, which you do either by taking additional lending from your current lender or by remortgaging to a new one for a larger amount. As your owned share grows, the rent you pay on the unowned portion falls — so staircasing both builds your equity and cuts your monthly rent.
Many owners remortgage to staircase and secure a better rate in the same transaction, which can be efficient — but adds moving parts, so good advice helps.
Staircasing: buying a bigger share
Staircasing is the heart of shared ownership remortgaging, so it’s worth understanding the mechanics. The crucial rule: each additional share is priced at the property’s current market value, not what you originally paid. That means if your home has risen in value, the extra share costs more than it would have at the outset. Here’s a worked example:
- You bought 40% of a property when it was worth £300,000 — so your share cost £120,000.
- You now want to staircase to 60%, and the property is worth £360,000.
- The extra 20% is priced at the current value: £72,000 (20% of £360,000) — not £60,000 (20% of the original £300,000).
- The £12,000 difference reflects the property’s appreciation. In a rising market, staircasing sooner is generally cheaper than later.
After staircasing to 60%, you’d pay rent only on the remaining 40% (down from 60%), reducing your monthly cost. How much you can staircase in one go depends on your lease: newer leases (broadly from April 2021) often allow buying as little as 1% a year for the first 15 years with no admin fee, while older leases typically require larger steps (often a minimum of 10%). Some leases — for example in certain rural “protected” areas — cap the maximum share you can own at 80%, and Older Persons Shared Ownership can cap at 75%, so always check your specific lease before planning. To fund the extra share, you’ll typically remortgage for a larger amount based on your new, bigger share, so the lender reassesses your affordability (how much you can borrow) and loan-to-value accordingly.

The 3-month valuation trap
This is the single most important practical warning for anyone staircasing, and it catches people out repeatedly. To set the price of your additional share, your housing association requires an independent RICS “Red Book” valuation of the property — carried out by a qualified surveyor. That valuation is usually only valid for three months. Here’s the trap: staircasing remortgages take time — instructing the valuation, agreeing it with the housing association, sorting the mortgage, and completing the legal work typically takes four to eight weeks, but can run longer if anything is delayed. If your remortgage doesn’t complete within the valuation’s three-month window, the valuation expires and you may have to pay for a fresh one — which, in a rising market, could come back higher, increasing the cost of your share. Delays are the enemy of staircasing. To avoid this, get your finance lined up early (ideally have a mortgage agreed in principle before the valuation), instruct an efficient solicitor experienced in shared ownership, and keep the whole process moving. A broker who understands the shared ownership timeline helps keep everything synchronised so the valuation doesn’t lapse. For the wider timeline, see how long a remortgage takes.
Reaching 100% ownership
The ultimate goal for many shared owners is staircasing to 100% — owning the whole property outright — and it’s worth understanding the significant benefits this unlocks. Once you own 100%:
- You pay no rent at all on the unowned share, because there’s no unowned share — often a substantial monthly saving.
- You access the full standard mortgage market. Instead of being limited to the smaller pool of shared ownership lenders, you can remortgage onto any standard residential mortgage, typically with more choice and potentially better rates.
- Most shared ownership restrictions fall away. The lease rules that limit how you use, alter or sublet the property generally no longer apply once you’re the full owner (though it usually remains leasehold if it’s a flat).
- You keep all the future gains. Any increase in the property’s value is entirely yours, rather than shared with the housing association.
Reaching 100% is a milestone worth planning toward. For example, if your home is worth £360,000 and you already own 60% (£216,000), buying the final 40% means funding £144,000 — usually through a remortgage that covers your existing share plus the new one. Because hitting 100% opens up the whole mortgage market, it’s often the point where owners get the biggest improvement in their deal, so it’s well worth reviewing your options with a broker at that stage.
Costs & the process
Beyond the price of any additional share, budget for the transaction costs of a shared ownership remortgage or staircasing:
- RICS Red Book valuation: typically £300–£600 (and remember the three-month validity).
- Solicitor / conveyancing: usually £1,000–£1,500, as a solicitor must review your lease, liaise with the housing association, and handle the transfer.
- Mortgage fees: any product, booking or valuation fees the lender charges.
- Housing association admin fees: some may apply (though newer leases often waive the fee for 1% staircasing).
All told, staircasing typically costs around £2,000 or more on top of the share price. The process usually runs: notify your housing association of your intention to staircase, instruct the RICS valuation, agree it with the association, arrange your finance (further advance or remortgage), and instruct a solicitor for the legal transfer — completing in around four to eight weeks. There can also be stamp duty implications depending on how you elected to pay it originally (in stages, or upfront on full market value), which is complex and worth taking legal advice on. If you’re purely remortgaging for a better rate without staircasing, it’s simpler and cheaper — closer to a standard remortgage, though still within the shared ownership lender pool. Either way, getting matched to the right lender and a shared-ownership-savvy solicitor keeps it smooth.
The bottom line
You can remortgage a shared ownership home, either to secure a better rate or to staircase into a bigger share — often both together. The lender pool is smaller than for standard mortgages but healthy, so matching to one that offers shared ownership and suits you is key. If staircasing, remember the extra share is priced at current market value (more in a rising market), and watch the three-month validity of the RICS valuation — delays that let it expire are the most common way staircasing goes wrong, so line up your finance early and keep things moving. Reaching 100% is the big prize: no more rent, full access to the standard mortgage market, and freedom from most restrictions. Budget around £2,000 in costs for staircasing, take advice on any stamp duty, and use a broker who knows shared ownership to keep it all synchronised.

Shared ownership remortgage: FAQs
Can you remortgage a shared ownership property?
Yes, you can remortgage a shared ownership property. There are two main reasons to do it: to switch to a better mortgage deal when your current one ends (avoiding your lender’s more expensive standard variable rate), or to staircase — borrow more to buy a bigger share of your home. Both are common and achievable. The key difference from a standard remortgage is that fewer lenders offer shared ownership mortgages, so your choice is more limited, though the list is healthy and includes major names. The process also involves your housing association and lease, not just the lender, and your circumstances and the lender’s criteria are reassessed since your original purchase. Because the lender pool is smaller and the lease and valuation add complexity, using a broker who specialises in shared ownership is particularly valuable to find the right deal and navigate the process smoothly.
What is staircasing on a shared ownership home?
Staircasing is buying additional shares in your shared ownership home to increase your ownership percentage — for example from 40% to 60%, or all the way to 100%. Each additional share is priced at the property’s current market value (set by an independent RICS valuation), not what you originally paid, so in a rising market the extra share costs more than it would have at the outset. Unless you have savings, staircasing usually means borrowing more, either through additional lending from your current lender or by remortgaging to a new one. As your owned share grows, the rent you pay on the unowned portion falls, so staircasing both builds equity and cuts your monthly rent. How much you can buy in one go depends on your lease — newer leases often allow 1% a year for 15 years with no admin fee, while older leases typically require larger steps of around 10% minimum. Reaching 100% means you own the property outright.
How much does it cost to remortgage or staircase shared ownership?
Beyond the price of any additional share you’re buying, staircasing typically costs around £2,000 or more in transaction costs. This includes a RICS “Red Book” valuation (usually £300 to £600), solicitor and conveyancing fees (typically £1,000 to £1,500, as a solicitor must review your lease and liaise with your housing association), any mortgage product or booking fees, and possibly a housing association admin fee (though newer leases often waive this for 1% staircasing). There may also be stamp duty implications depending on how you originally elected to pay it — in stages or upfront on the full market value — which is complex and warrants legal advice. If you’re simply remortgaging for a better rate without staircasing, it’s cheaper and closer to a standard remortgage, though still within the shared ownership lender pool. A broker can help you understand the full cost for your situation.
Why does the valuation only last 3 months?
When you staircase, your housing association requires an independent RICS “Red Book” valuation to set the price of the additional share, and this valuation is usually only valid for three months. This is because property values change over time, so the association needs a current figure. The three-month limit is the single most common way staircasing goes wrong: staircasing remortgages typically take four to eight weeks to complete, but if anything delays the process and it runs past the three-month window, the valuation expires and you may have to pay for a fresh one — which, in a rising market, could come back higher and increase the cost of your share. To avoid this, get your mortgage agreed in principle before the valuation, instruct an efficient solicitor experienced in shared ownership, and keep the process moving quickly. A broker who understands the shared ownership timeline can help keep everything synchronised so the valuation doesn’t lapse.
What happens when you staircase to 100%?
Reaching 100% ownership through staircasing brings significant benefits. First, you pay no rent at all, because there’s no longer an unowned share for the housing association to charge rent on — often a substantial monthly saving. Second, you can access the full standard mortgage market rather than being limited to the smaller pool of shared ownership lenders, which usually means more choice and potentially better rates, so it’s often the point where owners get the biggest improvement in their mortgage deal. Third, most shared ownership lease restrictions on how you use, alter or sublet the property fall away once you’re the full owner (though a flat generally remains leasehold). And fourth, any future increase in the property’s value is entirely yours rather than shared. Because reaching 100% opens up the whole mortgage market, it’s well worth reviewing your options with a broker at that stage to secure the best possible deal.
Which lenders offer shared ownership remortgages?
A healthy number of lenders offer shared ownership mortgages and remortgages, including major high-street banks and building societies — searches show owners looking specifically at names like Nationwide, Halifax, Barclays, HSBC and Leeds Building Society, among others. However, which lenders offer shared ownership products, their criteria, and their rates change regularly, and not every lender participates in this more specialist market, so the pool is smaller than for standard mortgages. Rather than approaching lenders one by one — and risking declines that leave credit footprints — the efficient approach is to use a whole-of-market broker who knows which lenders currently offer shared ownership remortgages and staircasing, and their criteria, and can match you to one likely to accept your application and offer a competitive rate. This is especially valuable because shared ownership criteria and the interaction with your lease and housing association add complexity that a specialist navigates routinely. nextmove can introduce you to such a broker, free.
