Nearly two-thirds of UK homeowners don’t realise how much their property’s ownership structure affects their long-term finances. That figure comes up again and again in the conversations I have with readers, and it’s the kind of blind spot that can cost tens of thousands of pounds. Whether you’re buying your first flat or downsizing in retirement, the legal form your ownership takes — freehold, leasehold, commonhold, or joint ownership — determines everything from your monthly costs to your ability to sell later on.
I’ve been writing about UK property for long enough to see the same confusion surface every time. People assume “buying a house” means owning the building and the land it sits on outright. Often it doesn’t. The rules are shifting fast too — resale market trends are being reshaped by leasehold reform, ground rent caps, and a push toward commonhold. Here’s what you actually need to know.
Freehold, Leasehold, and Commonhold Explained Simply
The most important thing to understand isn’t the textbook definition — it’s the consequence. Choose the wrong ownership structure and you could be paying ground rent that rises every decade, struggling to sell because the lease has dropped below 80 years, or discovering you have no control over repairs to the roof above your flat. Let me break down each one.
Freehold is straightforward: you own everything. No ground rent, no service charge, no permission needed to alter the structure. Most houses are freehold, and if you’re buying one, that’s the ideal. Leasehold is the norm for flats because multiple owners can’t each own the land a building sits on. The problem is that leasehold has been abused — ground rents that double every decade, opaque service charges, and leases so short they’re unmortgageable. The 2022 and 2024 Acts banned ground rent on new residential leases and made it cheaper to extend leases or buy the freehold. The draft 2026 Bill goes further, proposing commonhold as the default for new flats. Commonhold means you own your flat outright and share ownership of the building’s common parts with other residents — no lease, no ground rent, no freeholder. It’s already used in Australia and the US, and it’s finally coming to the UK at scale.
How Ownership Type Affects Your Finances and Selling Options
This is where the rubber meets the road. The DWP’s home ownership rule changes now mean that high-equity properties face enhanced review for Pension Credit and Housing Benefit assessments. If you’re a leaseholder in London or the South East with a property valued well above the national median, your benefit eligibility could be affected — even if your income hasn’t changed. That’s a shift from the old system where your main residence was largely excluded from means-tested calculations.
Consider a pensioner in Surrey with a leasehold flat worth £450,000 and 85 years left on the lease. Under the previous rules, that property wouldn’t have triggered a benefit review. Now, the DWP’s enhanced data sharing between departments and local authorities means the equity is visible and assessed. The practical consequence? Some homeowners are looking at equity release or downsizing earlier than planned to preserve their entitlement. If you’re in a high-value region, it’s worth checking how your ownership structure interacts with these new assessment methods before you make any big decisions.
My own view is that leaseholders with terms under 90 years should start the extension process now, even if they’re not planning to sell. The 2026 reforms will make it cheaper and simpler, but the process still takes months. Waiting until you’ve found a buyer is a recipe for a collapsed sale. If you’re unsure about your legal position, speaking to a property lawyer who specialises in leasehold reform can clarify your options before you commit to anything.
Where Buyers and Owners Get Tripped Up
The mistakes I see most often aren’t about choosing the wrong ownership type — they’re about not checking the details until it’s too late. Here are the three that cause the most trouble.
Ignoring the Lease Term Until You Try to Sell
This is the biggest one. A lease with 85 years remaining might feel fine when you move in, but lenders get nervous below 80 years. Below 70 years, most high-street lenders won’t touch it. The Leasehold Reform 2026 data shows that properties with leases under 80 years sell for 10–20% less than equivalent properties with longer leases. The fix is straightforward: extend the lease before you list. Under the 2024 Act, you can extend by 990 years with zero ground rent. But you need to start the process early — it typically takes 3–6 months.
Assuming Freehold Means No Ongoing Costs
Freehold owners don’t pay ground rent or service charges, but they’re still responsible for all maintenance, buildings insurance, and any major repairs. I’ve spoken to first-time buyers who budgeted for a mortgage and nothing else, then faced a £5,000 roof repair two years in. A Wi-Fi water leak detector is a small investment that can catch problems early, but the real lesson is to set aside 1–2% of the property’s value each year for maintenance. That’s not a rule of thumb I invented — it’s what surveyors recommend based on decades of repair cost data.
Overlooking the New EPC Requirements for Landlords
If you’re buying a property to rent out, the EPC C by 2030 target is non-negotiable. The government has confirmed the enforcement timeline, and the cost cap means you can’t be forced to spend more than £10,000 per property on upgrades — but you still have to reach a C rating. Properties with solid walls, no loft insulation, or old heating systems will be expensive to bring up to standard. Check the current EPC rating before you exchange contracts, and factor the upgrade cost into your offer. A property at EPC D or E might look cheap now, but the retrofit bill could wipe out your first few years of profit.

| Ownership Type | Key Cost | Resale Risk | Reform Impact |
|---|---|---|---|
| Freehold | Maintenance only | Low | Minimal |
| Leasehold (long) | Ground rent + service charge | Low if >90 years | Ground rent banned on new leases |
| Leasehold (short) | High extension cost | High below 80 years | 990-year extensions now possible |
| Commonhold | Shared maintenance | Low | Becoming default for new flats |
What to Do Before You Buy or Sell

The steps below are based on what I’d do if I were buying or selling a property today. They’re not exhaustive, but they cover the decisions that cause the most regret when skipped.
Check the Lease Term and Ground Rent Before You Offer
If you’re buying a leasehold property, ask for the lease document and the latest service charge statement before you make an offer. Look for the remaining term, the ground rent amount and escalation clause, and any restrictions on pets, subletting, or alterations. Under the 2024 Act, ground rent on new leases must be a peppercorn (effectively zero), but older leases may still have escalating ground rents. If the term is under 90 years, get a lease extension quote from a solicitor before you commit. The cost can run into thousands, and it’s better to negotiate that into your offer than to discover it later.
Understand How Joint Ownership Affects Inheritance
If you’re buying with a partner, decide whether you want to be joint tenants or tenants in common. Joint tenants means the survivor automatically inherits the whole property — useful for married couples but problematic if you want to leave your share to someone else. Tenants in common lets each of you own a defined share (often 50/50, but it can be any split) and leave that share in your will. This matters more than most people realise. If you’re not married and you own as joint tenants, your partner inherits everything automatically — which might be what you want, but if it isn’t, tenants in common gives you control. A estate lawyer can help you draft the right declaration of trust.
Plan for the 2026 Reforms If You’re Buying a New-Build Flat
The draft 2026 Bill proposes that all new flats must be sold as commonhold rather than leasehold. If you’re buying off-plan, check whether the developer is already offering commonhold. Some are transitioning early. Commonhold eliminates ground rent and gives you a direct say in building management through a commonhold association. The trade-off is that you’re jointly responsible for maintenance decisions with other owners — which works well in well-run buildings but can be frustrating if neighbours disagree on spending. If you’re considering a new-build, buying off-plan has its own set of risks and rewards, and the ownership structure is one of the most important to verify before you sign.
Review Your Property’s EPC and Plan Upgrades Early
For landlords, the 2030 EPC C deadline is closer than it sounds. The government’s cost cap of £10,000 per property means you can’t be forced into unaffordable upgrades, but you still need a plan. Start with the cheapest improvements: loft insulation, LED lighting, and a smart thermostat. Then move to heating system upgrades and solid wall insulation if needed. The EPC Energy Data tool lets you check any property’s current rating and fuel type. If you’re buying a rental property, factor the upgrade cost into your purchase price. A property at EPC E might need £8,000 of work to reach C — that’s a negotiating point, not a dealbreaker.
- 1Check the current EPC ratingUse the EPC register or HomeData tool. If it’s below C, estimate upgrade costs before you make an offer.
- 2Prioritise low-cost upgrades firstLoft insulation, draught-proofing, and a smart thermostat cost under £500 combined and can improve a rating by one or two bands.
- 3Plan major work for 2027–2028Heating system replacements and solid wall insulation are expensive and disruptive. Book contractors early — demand will spike as 2030 approaches.
- 4Keep records of all upgradesYou’ll need invoices and EPC certificates to prove compliance when you sell or remortgage.

Ownership law in the UK is changing faster than most people realise. The ground rent ban, the push toward commonhold, and the DWP’s new property assessments all point in one direction: the old assumptions about what it means to own a home no longer hold. My advice is to check the lease term, the EPC rating, and the ownership structure before you make any offer — and if you’re already a homeowner, review your position now rather than waiting until you need to sell.
