If your agency manages short lets, dabbles in holiday homes or simply advises landlords who are tempted by nightly rates, 2026 is the year the rules change. England is introducing a national short-term let registration scheme, and for the first time every qualifying property will need to carry a unique registration number before it can appear on Airbnb, Booking.com or Vrbo. This is a significant shift for a corner of the market that has, until now, operated with far lighter compliance obligations than the assured tenancy world you already know well.
This guide walks through what the scheme is, who it affects, what registration will require and how you can position your agency to help owners get it right. Some operational detail is still being finalised through 2026, so we have flagged the areas where the picture is not yet fully settled, and we have kept the focus on the practical steps you can take now.
What is the short-term let registration scheme?
From April 2026, England is introducing a national register for short-term lets. The policy grew out of years of concern about the growth of holiday lets in tourist hotspots, the loss of long-term rental stock, and the patchy visibility that local authorities had over who was letting what. A national register is intended to give councils a clear line of sight over the sector and to bring basic safety standards into a market that has often sat outside the usual private rented sector rules.
The headline mechanism is simple. Each qualifying property must be registered, and each registration produces a unique number. That number then has to be displayed on every platform where the property is advertised. Platforms will be required to check for a valid number, and listings that cannot produce one face being removed. In other words, registration is not a box-ticking formality that can be quietly ignored; without it, the listing itself becomes untenable.
It is worth being clear that this is a registration scheme, not a full national licensing regime in the way some had expected. It sits alongside existing local controls rather than replacing them, and precisely how the register interacts with local planning rules is one of the areas still being worked through. Treat the April 2026 start as the direction of travel, and expect the finer operational detail to be phased in and refined over the course of the year.
What counts as a short-term let?
The definition matters enormously, because it draws the line between a property that needs a registration number and one that does not. For the purposes of the scheme, a short-term let is accommodation provided for fewer than 90 consecutive nights where the guest does not use the property as their only or main residence.
Two elements do the work in that definition:
- Duration: the let must be for fewer than 90 consecutive nights. A single continuous booking that runs to 90 nights or more falls outside the short-term let definition.
- Not a main residence: the guest must not be treating the property as their only or main home. This is what separates a genuine holiday or business stay from a residential tenancy.
For agents, the useful mental model is a spectrum. At one end sits a nightly holiday booking on Airbnb, squarely within the scheme. At the other sits a standard assured shorthold or assured tenancy, governed instead by the framework you can read about in our guide to the Renters' Rights Act 2026. The tricky cases live in the middle: serviced apartments, corporate lets, mid-term stays and rolling monthly arrangements. When an owner asks you to advise, your first job is to work out honestly which regime the arrangement actually falls under, because getting that wrong exposes both you and the owner to the wrong set of obligations.
How registration and the unique number work
Registration happens per property, not per owner or per portfolio. If a landlord has three holiday cottages, that is three separate registrations and three separate numbers. Each property is assessed on its own facts, and each carries its own record on the national register.
Once registered, the property receives a unique registration number. That number must then be displayed on every listing platform the property appears on, whether that is Airbnb, Booking.com, Vrbo or any other channel. The platforms themselves are being brought into the enforcement chain: they will be required to check for a valid number, and a listing that cannot produce one faces being delisted. For an owner who depends on booking volume, a delisted property is not an inconvenience, it is a loss of income, so the incentive to register properly and on time is real.
For a multi-property agency, this creates an obvious administrative burden. You now have a set of registration numbers to hold, match to the correct listings, and renew before they lapse. Letting a number expire unnoticed could, in principle, put a live and earning listing at risk of removal. This is exactly the kind of expiry-and-renewal tracking that a portfolio platform like LettingGuru is built to handle, so that a lapsing registration surfaces as a task before it becomes a problem rather than after.
What registration will require
The register is not just a name-and-address exercise. Alongside the basics, owners will need to demonstrate that the property meets fundamental safety standards. Based on the scheme as it stands, registration is expected to require:
- The property address: the specific address of the accommodation being let.
- The accommodation type: what kind of property it is, so the register captures the nature of the let.
- The owner's identity: who is responsible for the property and the registration.
- A valid gas safety certificate: evidence that any gas appliances have been checked and are safe.
- An electrical installation condition report (EICR): confirmation that the electrical installation has been inspected and is satisfactory.
- Compliant smoke and carbon monoxide alarms: alarms that meet the Smoke and Carbon Monoxide Alarm (England) Regulations 2022.
None of these safety requirements will look unfamiliar if you already manage a residential portfolio, and that is the point. The scheme effectively imports a recognisable baseline of safety compliance into the short-let world. The practical challenge is documentation and currency: every certificate needs to be valid at the point of registration and kept up to date thereafter. An owner who cannot lay hands on a current gas certificate or a satisfactory EICR is an owner who cannot complete registration, which is where a well-organised agency earns its fee.
Enforcement and penalties
The scheme has teeth. Local authorities will be able to take action against unregistered lets, and the tools available to them are designed to make non-compliance costly and disruptive rather than merely embarrassing.
- Fixed penalty notices: financial penalties in the region of £2,500 to £7,500 for operating an unregistered let.
- Requests to platforms: councils can ask listing platforms to remove non-compliant listings, cutting off the property's route to market.
- Operational restrictions: further restrictions on how, or whether, a property can continue to operate as a short let.
For an agency, the reputational dimension matters as much as the financial one. If you are advising on or managing short lets, an owner who receives a penalty notice because a registration was missed will hold you at least partly responsible. Conversely, being the agency that keeps every managed short let cleanly registered and delisting-proof is a genuine selling point in a market where many owners are anxious and under-informed. Clean compliance records are not just a defensive measure; they are a commercial advantage.
The tax change that changes the maths
Registration is not the only 2026-era shift affecting short lets. The tax landscape has already moved. The Furnished Holiday Let (FHL) tax regime was abolished from 6 April 2025, and that has real consequences for the numbers behind a holiday let.
Under the old FHL rules, qualifying holiday lets enjoyed advantages that ordinary rental property did not, including certain capital allowances and more generous treatment of mortgage interest. With the regime gone, short-let income is now taxed as standard property income, in line with a normal buy-to-let. The practical effect is that the previous capital allowances and mortgage-interest advantages no longer apply, which narrows the tax gap that once made holiday letting look especially attractive.
This is general information rather than tax advice, and the specifics will depend on each owner's circumstances, so the right move is always to point owners towards a qualified accountant for a proper assessment. But it is useful context for any agent fielding the perennial question of whether a landlord should switch a property from long-let to short-let. The registration burden is going up at the same time as one of the historic tax incentives has gone away, and owners weighing the two models should be doing so with clear eyes.
London and local rules sit on top
The national register does not operate in a vacuum. It sits alongside existing local rules, and in some areas those rules are tightening independently of the national scheme.
London is the clearest example. The capital already has a 90-night annual limit on short lets of an entire home without planning permission. That limit predates the registration scheme and continues to apply, so a London owner has to think about both the annual night cap and national registration, not one or the other. Beyond London, some local authorities are introducing their own planning controls for short lets, including changes to use classes that treat a short-let property differently from a standard dwelling. The interaction between these local planning controls and the national register is one of the areas still being finalised, so it pays to check the position in each specific local authority rather than assuming a single national rule covers everything.
For agents operating across multiple areas, this patchwork is a reason to keep good local intelligence and clean per-property records. A registration number satisfies the national scheme; it does not automatically satisfy a local planning restriction or a borough night cap. Both have to be tracked, and the safest posture is to treat every property on its own local facts.
What letting agents should do now
The scheme is coming, the definition is known, and the safety requirements mirror ground you already cover for residential lets. That means there is plenty you can do before the operational detail is fully bedded in. A sensible checklist for any agency managing or advising on short lets looks like this:
- Identify your short lets: work through your book and flag every property that meets the short-term let definition, so you know exactly which ones will need a number.
- Help owners register each property: registration is per property, so build a plan that handles each holiday home separately rather than treating a portfolio as a single job.
- Get the safety certificates in order: make sure every short let has a current gas safety certificate, a satisfactory EICR and compliant smoke and carbon monoxide alarms, and keep the paperwork on file.
- Track numbers, renewals and expiry: record each registration number, match it to the right listings, and diarise renewals so nothing lapses unnoticed.
- Know the tenancy line: stay clear on where a genuine short let ends and an assured tenancy under the Renters' Rights Act begins, so each property sits under the right regime.
- Keep clean compliance records: maintain an audit trail that lets you prove, at any moment, that a managed property is properly registered and safety-compliant.
Much of this is document and deadline management at scale, which is precisely where the right software pays for itself. A platform like LettingGuru helps you track safety certificates and compliance documents across an entire portfolio, so registration numbers, gas certificates, EICRs and alarm records live in one place with renewal reminders attached. If you are already tightening up on the residential side, it is worth reading our guide to the EPC C deadline for 2030 alongside this one, since the same disciplined, records-first approach serves you well across every strand of compliance your agency has to manage.
The short-term let registration scheme is a meaningful new obligation, but it is not an unmanageable one for an agency that gets organised early. If you want a single system to keep your short lets, safety certificates and compliance deadlines under control, you can start a free trial of LettingGuru and put the groundwork in place before the scheme goes live.
