The 40% Flat Discount: A Landlord's Framework for the Leasehold Gap

Zoopla's latest analysis of the flat and house price gap makes uncomfortable reading for anyone hoping the leasehold flat market is quietly recovering. It isn't. Across the UK, flats now cost 40% less than houses on average. The gap is the widest it has been for 30 years, and outside London a house typically costs 2.3 times the price of a flat, up from 1.8 times a decade ago.

Buyers are hesitating. Flats take an average of 42 days to sell in England and Wales against 33 days for houses. In Scotland, where there is no long leasehold system for flats, that difference disappears. Flats and houses both sell in 15 days.

The Zoopla piece is written for estate agents wanting to shift stock. Read from a landlord's chair, the numbers say something else. There is a category of asset that most buyers will not touch. That means the landlords who can accurately price the risk are competing against a much smaller field, in a market where the underlying rental demand for well-run flats has not fallen away. That is not a bargain hunt. It is informed access.

The distinction matters. Bargain hunting assumes the market is wrong. Informed access assumes the market is broadly right about the category and wrong about individual assets within it. What separates one leasehold flat from another is not luck. It is diagnosis.

Why the discount exists

The discount is not irrational. It reflects a real set of complexities that make a leasehold flat genuinely harder to own, harder to sell and harder to remortgage than a freehold house. Service charges have risen sharply since 2020, driven by building insurance premiums, post-Grenfell remediation costs and rising management fees. Ground rents on some pre-2022 leases still escalate on 10 or 25 year cycles. Short leases become expensive to extend once they drop below 80 years. Buildings taller than 11 metres now sit inside a building safety regime that continues to evolve.

None of this is invented. What is invented is the assumption that these problems apply uniformly across every leasehold flat. They do not. A well-managed building with a long lease, a stable service charge history and a competent freeholder is a fundamentally different asset from a poorly managed block with a decaying lease and unresolved remediation exposure. The market largely treats them as the same. That is the gap an informed landlord can price.

What reform will and will not fix

Landlords hearing "leasehold reform is coming" need to be precise about what that actually means in July 2026.

The Leasehold and Freehold Reform Act 2024 received Royal Assent in May 2024. Most of its provisions, including the ones that would make lease extensions cheaper and easier, are not yet in force. The Government has confirmed that a valuation rates consultation is still expected in 2026, and technical flaws in the 2024 Act need to be fixed before enfranchisement provisions can be switched on.

The Commonhold and Leasehold Reform Bill, published in draft in January 2026 and confirmed in the May 2026 King's Speech, is targeted for Royal Assent by mid-2027 if the parliamentary timetable holds. The Bill's headline measures include a £250 cap on existing ground rents (reducing to a peppercorn after 40 years), a mechanism to make commonhold conversion easier, and an eventual ban on most new leasehold flats.

Two things matter for landlords buying now. First, the ground rent cap is currently expected to take effect around 2028, with the Select Committee pushing for late 2027. Second, existing leases will remain leasehold. Reform makes conversion easier but does not force it. A leasehold flat you buy today is very likely still a leasehold flat in five years.

That means reform is directionally supportive but does not rescue a poorly chosen asset. Buying a flat with a 78 year lease and hoping reform will make the extension cheap enough to fix your yield is a bet on parliamentary timing, not a compliance decision. The safer position is to buy the lease you want to own and treat any reform benefit as upside rather than as the plan.

Five diagnostic questions, from a landlord's chair

Zoopla's five checks for buyers are a reasonable starting spine but they are agent-facing. From a landlord's perspective, each question changes shape.

1. Lease length: what will this lease be worth at your exit?

The question is not just how long is left on the lease today. It is how long will be left when you plan to sell or refinance. A 95 year lease sounds comfortable until you realise a 15 year hold takes it to 80 years, the threshold at which marriage value applies under the current regime and where lender appetite starts to tighten.

If reform lands on the timeline currently expected, marriage value abolition should reduce extension costs for many leases. But that reform is not yet in force, and the valuation rates that will determine the new cost basis are still to be consulted on. For a purchase you are making in 2026, model the extension cost under current rules and treat any post-reform saving as a bonus.

The practical position: know the lease length, know the current cost of extension, and know what both figures will be at your realistic exit horizon.

2. Service charges: what is the trajectory, not just the history?

Zoopla recommends three years of historical service charges. For a landlord that is table stakes. What you actually need is a view on where charges are going next.

That means asking for Section 20 consultation notices for any major works currently under consideration, the buildings insurance renewal history and current premium, any First-tier Tribunal history involving service charge disputes on the block, and the reserve fund balance against known future liabilities. If the block has an EWS1 certificate but works are pending, you are buying a share of that future cost.

The yield question is not what did service charges cost last year. It is what proportion of your gross rent will service charges consume in year one, year three and year five. Any lender will apply a stress test to your total outgoings. Some will not lend where annual charges exceed 1% of property value. That is a real constraint on refinancing, not a theoretical one.

3. Ground rent: what does it do to your lender pool?

The £250 cap in the draft Bill applies to existing leases, but not yet. The Court of Appeal has given freeholder groups permission to appeal earlier High Court rulings on related reform, so the final position is not yet settled.

In the meantime, the practical constraint for a landlord is lender appetite. A significant number of BTL lenders decline where ground rent exceeds 0.1% of property value, or where the lease contains doubling or RPI-linked escalation clauses. If you can only remortgage with a shrinking pool of lenders, your future refinancing rates will be worse regardless of what the Bank of England does.

The question to answer at purchase is not whether the current ground rent looks affordable. It is whether the ground rent clause, in its current form, keeps your future lender pool intact.

4. Building safety: whose costs are these, and are they finished?

The EWS1 certificate is one input. It tells you what the external wall assessment currently says. It does not tell you whether remediation is complete, whether the block sits inside the Building Safety Act 2022 higher-risk category (18 metres or seven storeys and above), or how the costs of any outstanding works will be apportioned.

The Government confirmed a Remediation Bill in the May 2026 King's Speech, aimed at speeding up cladding remediation and shifting more cost onto manufacturers. That is a genuine step forward for buildings still stuck in remediation limbo. It does not change the fact that some works still fall on leaseholders, and that a landlord buying a flat in a mid-rise block (11 metres or above) needs to know exactly which regime applies to that building and what liabilities remain.

The diagnostic question is not "is there an EWS1". It is what has been assessed, what works are outstanding, who pays for them, and what is the timeline to completion.

5. Reform readiness: how does reform actually land on your specific asset?

Zoopla recommends promoting the benefits of leasehold reform to buyers. For a landlord, the more useful question is how the reform pipeline changes the specific asset you are considering.

Some reforms will help immediately once switched on: cheaper lease extensions under the amended LAFRA 2024 provisions, and the eventual ground rent cap. Some will help only if you choose to act: commonhold conversion is being made easier but is not automatic. Some will not help at all with your existing lease: the ban on new leasehold flats affects new build stock, not the second-hand market you are likely buying in.

The realistic position for a landlord buying in 2026 is that reform improves the exit conditions of a well-chosen asset and does not repair a badly chosen one. Model the asset under current rules. If it works under current rules, reform is upside. If it only works assuming reform arrives on schedule and delivers the strongest version of every proposal, it does not work.

What happens after exchange

The five questions above are how a landlord decides whether to buy a specific leasehold flat. They are not the end of the compliance work. They are the setup for it.

Once you exchange, you have a defined window before completion to line up everything a property needs to let from day one. Gas safety, electrical installation condition report, EPC at the required standard, smoke and CO alarms, deposit protection registration, and, depending on the borough and property type, a licence application. You may also need other documents depending on the property type and which council it is in. Any one of these can extend a first void by weeks if it is missed or discovered late.

Compliance Shield is built for that window and everything that follows it. From the day a landlord knows completion is coming, we identify the compliance gaps that would delay a first tenancy, sequence the work that needs doing, and log every certificate, communication and contractor chase in one place. Two things change as a result. First, initial voids get shorter, because a landlord is not discovering a missing certificate or a licence requirement the week the property should be advertising. Second, from day one of ownership there is a dated evidence trail of what was known, what was actioned and when. That trail is what matters when a lender questions a remortgage, a tenant raises a disrepair complaint, or a council opens an enquiry.

That is the four-pillar frame Compliance Shield is built on. The landlord provides the will to act. Compliance Shield provides the expertise to diagnose the gaps. The process captures every communication and decision. The evidence trail proves what was known and when.

For a landlord willing to buy the right leasehold flat, this is the most affordable the category has been for 30 years. The demand for well-run flats has not gone anywhere. What separates the landlords who benefit from that discount from the landlords who get caught by it is not luck. It is diagnosis, and then a fast start.
