The FHL regime is gone and Use Class C5 arrives this summer. A national registration scheme is rolling out across England. STL operators in the Lake District, Cornwall and the Cotswolds now face a potential planning application on top of a higher tax bill. The compliance picture looks nothing like 2023.
What Has Happened?
England's national short-term let registration scheme was legislated through the Levelling Up and Regeneration Act 2023, which gave the government powers to create a mandatory register. The scheme is rolling out during 2026, initially on a voluntary basis and moving to mandatory once the online portal and platform integration is live. Every property used for short-term commercial letting must register and receive a unique registration number. That number must appear on all listing platforms, including Airbnb, Booking.com and Vrbo. Once the mandatory phase is in force, platforms are prohibited from accepting or publishing listings without a valid registration number. Failure to register is an offence. Local authorities receive the registration data and can identify properties operating commercially without appropriate planning consents in their area.
Running alongside the registration scheme is Use Class C5 for short-term lets. The Use Class Order amendment, which creates a distinct planning category for properties let commercially as short-term accommodation, is expected to come into force during summer 2026 by statutory instrument. No SI had been laid as of early June 2026, but the government has confirmed the intent and industry sources are pointing to July to October as the likely window. When C5 arrives, existing properties already dedicated to STL use are automatically reclassified into the new class without any planning application. The significant change comes for new STL operations and for local authority designation of Control Zones.
Under the C5 framework, changing a property from C3 residential to C5 short-term let use will normally be permitted development, no planning application required. The power that matters is what local authorities can do after C5 is in force: they can designate specific areas as Control Zones, removing that permitted development right. In a Control Zone, a new STL operation requires a full planning application. Lake District National Park Authority, several Cornish councils and Edinburgh City Council have all publicly indicated an intent to use equivalent powers to restrict STL growth in housing-pressured tourist areas. This is not a distant prospect. It is an active direction of travel in markets where Airbnb has demonstrably reduced residential housing stock.
Scotland's experience is instructive. The mandatory STL licensing regime there came into force in October 2022. Edinburgh designated the entire city as a control area, meaning every existing STL had to apply for a licence rather than simply registering under a lighter scheme. Processing times in Edinburgh ran to twelve months or more in many cases. A meaningful share of applications were refused, withdrawn, or abandoned. England's C5 regime is less restrictive by default than Scotland's licensing approach, but it hands local authorities the same underlying lever. Wales introduced its own registration requirement for all holiday accommodation earlier in 2026, adding an administrative layer for Welsh operators on top of the FHL tax changes that hit from April 2025.
Why This Matters to UK Property Investors
The FHL abolition removed the income tax advantages. The registration scheme and C5 add compliance obligations and, in designated Control Zones, a genuine planning barrier. For investors who kept running properties as STLs after April 2025, the net income calculation looks materially worse than it did in 2023: higher income tax, a registration overhead, and in tourist-heavy areas, a prospective planning uncertainty that was simply not in the model before.
The planning risk is not about existing operations. Existing STLs get auto-reclassified into C5 when the SI arrives and are not immediately subject to a planning application. The risk is prospective: an investor buying a residential property today in a tourist-heavy location with the intention of running it as an STL needs to assess whether a Control Zone designation is coming. Lake District, Cornwall, the Cotswolds, coastal Suffolk, Pembrokeshire. These are the markets where local authority appetite to restrict STL growth is most clearly signalled. Completing on a £280,000 property in a Cornish fishing town, receiving a Control Zone notice six months later, and discovering that continuing to operate as an STL requires full planning permission that may or may not be granted is a specific and avoidable risk.
Urban STL operators in Manchester, Leeds and Birmingham are in a different position. English urban councils have not shown a strong appetite for Control Zone designations in city centres, because the housing pressure there comes from supply shortage rather than STL conversions draining residential stock. A Manchester city centre flat running 150 Airbnb nights per year is not the same planning problem as a stone cottage in Ambleside that could house a family of four. The political and planning context differs and the Control Zone risk for city centre STL investors is lower, at least in the near term.
London is a specific case. The 90-day annual limit on residential STL use has been law under the Greater London Council (General Powers) Act since 2015. Registration data will let councils cross-reference platform booking records against property registrations far more systematically than has been possible until now. If you have been running 130 or 150 nights per year in a London flat on the assumption that councils are not checking, that assumption is weakening. Southwark, Westminster and Kensington and Chelsea have been actively enforcing the limit since 2022. Registration makes their job substantially easier.
The Risks Investors Need to Understand
C5 is not yet law. No statutory instrument has been laid as of early June 2026. The government has confirmed the intent and the consultation is closed, but "summer 2026" in planning legislation terms means anything from July to October. An investor making a purchase decision on the basis that C5 arrives in a specific month is working from an assumption, not a fact. The policy direction is unambiguous. The exact commencement date is not.
Control Zones require affirmative local authority action after C5 comes into force and will not exist everywhere on day one. The risk for a Cornwall or Cumbria STL investor is medium-term rather than immediate: holding into a five-year period during which a Control Zone may or may not be designated, during which planning permission may or may not be required, and during which a planning application may or may not succeed. That particular uncertainty was simply not in any STL investor's hold-period model two or three years ago.
Running an STL on a standard residential mortgage without lender consent is a specific exposure the registration scheme makes worse. Many residential mortgage terms prohibit commercial STL use. When the FHL regime existed a small number of lenders offered FHL-specific products. Those products disappeared with the FHL regime. A government-held registration database, visible in principle to lenders, makes undisclosed STL use harder to sustain indefinitely. I would not rely on it going unnoticed through the medium term.
The income tax position from April 2027 tightens further for personal STL operators. Property income including STL rental will be taxed at 22%, 42% or 47% from 6 April 2027 under the Finance Act 2026. Section 24 mortgage interest restrictions apply at the 22% basic rate credit from the same date. For a higher-rate STL operator, rental profits above the basic rate band move to 42% from April 2027. An operator who absorbed the FHL abolition in April 2025 and kept running faces a second income tax hit in April 2027. That second hit lands fourteen months from now, and the January 2027 self-assessment return, covering the first full post-FHL year, arrives before it.
Where the Opportunity Could Be
The compliance squeeze on STL operators in tourist-heavy markets is producing a category of seller who is exiting for administrative reasons rather than because the income has collapsed. The registration requirement, the planning uncertainty, the income tax changes, the lender exposure risk, the accountancy complexity of operating what used to be a simple Airbnb: cumulatively these overheads are prompting hobby and small-scale operators to sell. That seller is often sitting on a debt-free asset in a location with sustained tourist demand and, in many cases, year-round residential demand underneath the tourist trade. That is motivated selling from a position of genuine equity, which is a reasonable acquisition context.
Coastal towns with year-round residential demand alongside tourism are the clearest targets. Newquay TR7, Scarborough YO11 and YO12, Falmouth TR11, Filey YO14, Lyme Regis DT7. These have NHS workers, council staff, hospitality employees and local businesses generating tenant demand in October as well as August. A two-bed former STL property in Newquay at £185,000 letting at £800 to £900 per month as a standard long-term rental is a gross yield of 5.2% to 5.8%. Not exceptional by North East standards but ahead of the national average, with lower management intensity than short-term operation and no Airbnb commission at 15% to 18% cutting the gross income.
Urban STL exits are coming too, and on a different timeline. Manchester M1 to M3, Leeds LS1 to LS2, Nottingham NG1. The Finance Act 2026 income tax hit from April 2027 applies equally to urban STL operators. An investor with three Manchester city centre flats running as Airbnb who survived the FHL abolition will face 42% on those profits from April 2027. Some will sell. Manchester city centre flats from STL operators reconsidering the model can be acquired at BTL gross yields of 5.5% to 6.5%, with strong underlying rental demand from the city's student, young professional and corporate relocation tenant pools.
Edinburgh is worth specific attention. City-wide STL licensing, in force since October 2022 with mandatory applications for every existing STL, produced demonstrable operator exit: an assessment of the regime found roughly 22% of Edinburgh's pre-licensing STL stock left the market within eighteen months of the mandatory date, not because licences were refused but because operators decided the overhead was not worth it. Licence renewal deadlines in Edinburgh fall in late 2026 and into 2027. Some Edinburgh operators who obtained their licence in 2023 and have since absorbed the FHL tax changes will not renew. Edinburgh city centre flats from exiting STL operators at BTL gross yields of 4.5% to 5.5% are a capital growth play in a city that Savills projects well within its top-tier five-year growth forecast.
Arsh's Investor View
The FHL post I wrote on 3 June covered the income tax hit: CGT at 24%, Section 24 applying, capital allowances gone. What I wanted to add then but ran out of space for is the planning framework being built alongside it. The two are separate policies from separate parts of government, but they point in the same direction. The registration scheme puts every STL into a government database. C5 gives local authorities the legal mechanism to require planning permission in tourist-heavy areas. Together they move STL operation from something you could do quietly with an Airbnb account and an FHL tax return into something that requires active compliance management, visible to local authorities and platforms.
My read on what Scotland tells us is specific. Edinburgh enacted a whole-city control area. The result was not mass forced closure. It was administrative overhead that filtered out operators running one or two properties as a side income stream, because the overhead cost and uncertainty ratio did not work for them at that scale. The serious commercial STL operators, the ones with five or more units and professional management, largely obtained licences and continued. England's C5 regime is less blunt than Edinburgh's control area approach but it produces the same filtering dynamic in any area that enacts a Control Zone. It prices out small-scale operators. That is an acquisition opportunity if you are positioned to pick up what they sell.
The lender point is one I do not see discussed enough. A lot of STL properties are running on residential mortgages where the lender's terms either prohibit STL use entirely or require notification and consent. The FHL regime created a sort of informal tolerance because the tax treatment implied a degree of commercial legitimacy. That has gone. Registration creates a government-held record that, over time, lenders can query. I would not be comfortable holding a property on a residential mortgage while running it as a registered STL, and I think some operators who have been comfortable with that arrangement until now need to rethink it before the mandatory registration phase kicks in properly.
On whether STL still makes sense after all of this: honestly, it depends on the scale and the location. Three to five well-located urban units with a professional management company, operated in the company structure for tax efficiency, with the correct mortgage products in place, still works as a business. One or two coastal properties bought on a residential mortgage, managed personally, relying on FHL reliefs that no longer exist, in a market heading toward a Control Zone, while preparing for the January 2027 self-assessment that will show the first real post-FHL bill: that is a much harder case to make. The operators who fall into that second description are the ones creating the acquisition opportunity I described above. They are not stupid. The maths just changed on them.
How Property Investor App Can Help
Property Investor App lists buy-to-let opportunities across coastal towns, regional cities and northern markets from direct sellers and sourcing agents, with asking price, rental income and yield data in every listing. For BTL investors watching the STL exit wave in coastal towns or city centre markets, PIA gives you visibility of former STL properties coming to market directly from sellers before they reach open market listing. For STL operators who have worked through the updated numbers under registration, C5, and the April 2027 income tax changes and decided the operation no longer stacks up, PIA connects you with portfolio buyers who understand the STL-to-BTL conversion case and can complete chain-free on the right properties.
Key Takeaways
- England's national short-term let registration scheme is rolling out in 2026 under powers in the Levelling Up and Regeneration Act 2023. Every property used commercially as a short-term let must register and display a unique registration number. Once mandatory, platforms including Airbnb and Booking.com will be prohibited from listing unregistered properties. Local authorities receive registration data and can use it to identify properties operating without appropriate planning consents and to enforce the 90-day annual limit in London.
- Use Class C5 for short-term lets is expected to be enacted in England by statutory instrument during summer 2026. Existing dedicated STLs are automatically reclassified into C5 and need no planning application. Changing a C3 residential property to C5 STL use will normally be permitted development. The significant power is that local authorities can designate Control Zones, removing that permitted development right in specified areas and requiring full planning permission for new STL operations.
- Control Zone designations are expected first in tourist-heavy markets with active housing stock concerns: Lake District National Park, several Cornish councils, coastal Suffolk, and equivalent Scottish and Welsh markets with separate national licensing and registration frameworks. In those areas, an investor buying a residential property today with STL intent is buying into a medium-term planning uncertainty that was not present in 2023.
- Scotland's mandatory STL licensing regime, in force from October 2022 with Edinburgh designated a whole-city control area, saw approximately 22% of the city's pre-licensing STL stock exit the market within eighteen months. Not due to licence refusals, but because small-scale operators decided administrative overhead was not worth running at their scale. England's C5 framework, combined with registration requirements and the loss of FHL tax reliefs, produces the same filtering dynamic in any area that enacts a Control Zone.
- For the income tax picture: all STL rental income has been taxed as standard property income since 6 April 2025. No capital allowances, no Business Asset Disposal Relief, Section 24 mortgage interest restrictions applying. From 6 April 2027, rental income (including STL) is taxed at 22% basic rate, 42% higher rate, 47% additional rate under the Finance Act 2026. Operators who absorbed the FHL abolition and continued running STLs face a second income tax increase fourteen months from now.
- Acquisition opportunity: STL operators exiting due to compliance overhead are producing motivated sellers in coastal towns with genuine residential demand (Newquay TR7, Scarborough YO11-YO12, Falmouth TR11) at prices supporting BTL gross yields of 5.2% to 5.8%, and in city centre markets (Manchester M1-M3, Edinburgh centre) at 5% to 6.5% gross yield. Edinburgh licence renewal deadlines in late 2026 and 2027 are the most specific near-term trigger for STL property coming to market in a high-capital-growth city.
Frequently Asked Questions
What is Use Class C5 for short-term lets in England?
Use Class C5 is a new planning category for properties let commercially as short-term accommodation, separate from the existing C3 residential use class. It is expected to be enacted by statutory instrument amending the Town and Country Planning (Use Classes) Order 1987 during summer 2026. When in force, existing dedicated STLs are automatically reclassified into C5 without a planning application. Changing a C3 residential property to C5 short-term let use will normally be permitted development. The significant new power is that local authorities can designate Control Zones, removing the permitted development right in defined areas and requiring full planning permission for new STL operations. Properties in Control Zone areas that are already operating as STLs are auto-reclassified into C5 and are not immediately required to submit a planning application for their existing use.
When does the England short-term let registration scheme become mandatory?
The short-term let registration scheme in England is legislated through the Levelling Up and Regeneration Act 2023. It is rolling out in 2026 via an online portal, with voluntary registration before moving to mandatory. Once mandatory, every property used commercially for short-term letting must be registered and display a unique registration number on all listings. Platforms including Airbnb, Booking.com and Vrbo will be required to display registration numbers and will be prohibited from listing unregistered properties. The exact mandatory commencement date is subject to statutory commencement orders and portal readiness. Operating without a registration number after the mandatory requirement is in place is a criminal offence, with local authorities empowered to issue fines and request platform listing removals.
How does the short-term let registration scheme affect London landlords?
In London, short-term letting of a residential property for more than 90 nights per calendar year already requires a change-of-use planning permission under the Greater London Council (General Powers) Act 1963 as amended. The national registration scheme adds a separate requirement: all London properties used commercially as STLs must register regardless of the number of nights let. Once mandatory, registration data will allow London councils to cross-reference platform booking activity against property records and enforce the 90-day limit more systematically than has been possible until now. Southwark, Westminster and Kensington and Chelsea have been actively enforcing the limit since around 2022. Registration does not change the underlying rule but it substantially strengthens enforcement infrastructure.
What happened to Furnished Holiday Let properties after the FHL regime was abolished?
The Furnished Holiday Lettings tax regime ended on 6 April 2025. From that date all STL income is taxed as standard property income: income tax at personal rates (22%, 42%, 47% from April 2027 under Finance Act 2026), Section 24 mortgage interest restrictions providing a basic rate credit only (20%, rising to 22% from April 2027), and CGT at 18% or 24% on disposal. Capital allowances on furniture and equipment, Business Asset Disposal Relief at 10% CGT, and the ability to count rental income as relevant UK earnings for pension purposes are all gone. Around 127,000 qualifying FHL operators were affected. Those who continued running properties as STLs after April 2025 now also face the registration scheme and the C5 planning framework, adding compliance obligations on top of the income tax changes.
Are short-term lets still worth running after the FHL abolition and C5 planning rules?
The arithmetic depends on location, property count, management structure, and tax position. For professional operators with multiple well-located urban units, correct mortgage products and a limited company structure, the income can still justify the operational complexity. For small-scale operators with one or two coastal properties on residential mortgages, running STLs personally and relying on FHL reliefs that no longer exist, in markets heading toward Control Zone designation, the post-2025 position is harder to justify. The compliance overhead has risen substantially: registration, potential planning applications in Control Zones, higher income tax, mortgage terms risk, and accountancy complexity. Scotland's experience suggests this overhead filters out small-scale operators at roughly a 20% exit rate within eighteen months of a mandatory compliance event. For BTL investors, that exit rate creates acquisition opportunities in coastal markets at 5% to 6% gross yields and in city centre markets at comparable or better levels.
