C5 Use Class & Holiday Let Planning Permission UK — Architect's Guide
We design carefully considered eco homes and luxury holiday homes that perform well, age gracefully, and make long-term financial sense. RIBA Chartered Architects.
Do you need planning permission for an Airbnb or holiday let?
Yes — in many cases, you do need planning permission for a holiday let or Airbnb in England, and the rules are tightening. The government is introducing a new Use Class C5, which formally separates short-term holiday lets from ordinary homes. Depending on where your property is, this may require you to apply for planning permission before you can legally operate.
I'm Peter Markos, a RIBA Chartered Architect specialising in eco and luxury holiday homes. I've helped landowners and investors navigate exactly these questions, and the most expensive mistakes I see happen when people act before checking their local planning position.
In this article, I'll explain what C5 means for your project, when you need permission, and how to approach it in a way that protects your investment.

An Architect’s Insight: What the C5 Use Class Means in Practice
From our perspective, the introduction of a dedicated use class for short-term holiday lets is a welcome and overdue change. For years, the sector has operated in a planning grey area, with many properties functioning as de facto holiday accommodation without clear consent or consideration of their wider impact on local communities. In practice, we’ve seen holiday lets variously treated as Class C2, Class C3, or even sui generis, depending on location and interpretation. This inconsistency has left landowners and investors understandably confused about what is, and isn’t, allowed.
One of the most common misconceptions we encounter is the assumption that planning permission is not required for a holiday home. In reality, it very often is, and yes, this can still apply even if the accommodation is on wheels.
Local authorities have, to date, taken markedly different approaches. Some councils view holiday lets as a positive driver of tourism and the local economy, and have adopted a relatively permissive stance. Others, particularly in areas facing housing shortages, have begun to push back, even ahead of formal C5 implementation. In popular destinations where short-term rentals risk displacing long-term residents, councils are increasingly seeking stronger controls to protect housing stock. A dedicated use class brings transparency to this landscape. Property owners gain clearer guidance on what is permissible, communities gain reassurance that holiday lets will be properly managed, and responsible investors can proceed with greater certainty.
As architects specialising in holiday home design, we also see a clear upside in terms of quality and accountability. When holiday lets are formalised through the planning system, they are more likely to be treated as long-term assets rather than temporary loopholes. This typically leads to better design decisions, more robust facilities, and greater investment in sustainable, well-considered buildings that sit comfortably within their setting. While some may view tighter regulation as a hurdle, we see it as part of running a professional, future-proof holiday rental business; ultimately, a positive step for guests, communities, and landowners alike.

With planning rules shifting, it’s worth getting a clear picture of how the new C5 use class could affect your holiday let or Airbnb plans. A short call is often enough to understand what’s changing and how it applies to your specific property. On the call, we can cover:
• Whether your home or site is likely to fall under C5
• How Article 4 Directions might affect you
• What councils are doing in your area
• The best route forward for new or existing holiday lets
Does Article 4 Stop You Using a Property as a Holiday Let?
Even before the C5 use class is officially rolled out, some local councils have already taken action using Article 4 Directions. An Article 4 Direction is a planning tool that lets a council remove “permitted development” rights in specific areas. In plain English, this means the council can require you to seek planning permission for changes that would normally be allowed without one. And yes, that can include turning a dwelling (Class C3) into a short-term holiday let.
For example, in a town with an Article 4 Direction targeting holiday lets, you must apply for planning permission to use your property as an Airbnb, even under the current planning framework. Councils typically invoke Article 4 in areas facing acute housing pressure or where there’s a danger of communities being “hollowed out” by too many vacation rentals. It’s a way local authorities control holiday homes, if they believe local families are being priced out. Notably, London has long had a 90-night limit on short-term rentals before permission is needed; that’s a separate rule, but it stems from the same concern about balancing housing needs.
If your holiday let is in an area with an Article 4 Direction, consider it a red flag: you’ll likely need full planning approval to continue or start short-term letting. Many popular UK destinations (certain parts of Devon, Cornwall, Cumbria, etc.) are watching these developments closely. The takeaway is that national policy might say one thing, but your local council can have the final say. Always check local planning maps or consult with a planning professional if you’re unsure. Skipping permission where it’s required can lead to enforcement action; it’s not worth the risk, so please check.

Can Councils Refuse C5 Planning Permission for Holiday Lets?
Yes — and some already are, even before C5 is formally in place. Here's what the proposed changes mean in practice:
Class C5 (Short-Term Let Homes) — A new dedicated use class for properties used as short-term holiday accommodation, such as Airbnbs and vacation cottages. This formally separates holiday lets from ordinary dwellings (Class C3). The significance of this is that what was previously a grey area becomes a defined planning category — one that councils can actively control.
Planning Permission Requirements — Changing a property from residential (C3) to a holiday let (C5) may require planning permission, depending on your local authority. The government intends to allow this change under permitted development nationally, but councils can opt out. In practice, this means the answer to "do I need permission?" varies significantly by location. Some councils will be permissive. Others, particularly those under housing pressure, will not. Assuming you don't need permission is the mistake I see most often — and it's an expensive one.
Article 4 Directions — This is where it gets serious. Local authorities can use Article 4 powers to remove permitted development rights in specific areas. If your site falls within an Article 4 Direction targeting holiday lets, you will need full planning permission — even to continue operating an existing let. This is already in effect in parts of the country and is expanding. It is not a technicality. Enforcement action is real.
Impact on Quality and Standards — There is a genuine upside here. When holiday lets enter the formal planning system, owners become accountable for design, parking, waste, noise, and safety. For anyone investing seriously in a high-quality holiday property, this is a levelling-up moment. The operators who cut corners will find it harder. The ones who design responsibly and plan properly will stand out.
One important note if you already operate a holiday let, current proposals suggest existing, legally operating holiday lets will be automatically reclassified to C5 without needing a fresh application. You are not expected to lose your existing use overnight. The focus of the new rules is on regulating new and expanded short-term lets going forward, but I'd strongly recommend confirming your position with a professional rather than assuming you're automatically protected.
How to Future-Proof Your Holiday Let or Airbnb Project
If you’re planning a luxury holiday let, eco cabin, or Airbnb, the new C5 planning rules make forward-thinking design essential. Here’s how to future-proof your project and avoid costly missteps:
Understand Local Planning Policy Early: We often hear from people who have already bought land, only to find that planning permission is uncertain. Before purchasing land or changing a property’s use, understand your council’s stance on holiday lets. Check for Article 4 Directions, local caps, or emerging restrictions. A pre-application enquiry and a clear grasp of the rules can prevent costly mistakes.
Engage Professionals: A good professional ultimately saves you time and money. When assessing land or seeking C5 use class approval, it’s important to take advice from a RIBA Chartered Architect or a chartered planning consultant (RTPI-accredited). Early professional input can clarify what is realistically achievable and help you avoid costly missteps before you commit.
Design with Sensitivity: Show that your project will benefit the area. Thoughtful design, for example, using natural local materials, eco-friendly features, and providing adequate parking, can demonstrate that your holiday let will be a well-considered addition to the community and local area. Eco-Home features, such as off-grid energy systems, not only appeal to guests but also signal to locals and the broader community a care for the locality.
Plan for the Long Term: Use Class C5 looks set to be implemented, and the direction of travel is clear. By getting your planning position right now — rather than waiting — you protect your investment, reduce your risk, and create an asset with a clean planning history behind it. A properly consented holiday home is easier to operate, easier to finance, and more valuable if you ever decide to sell.
Once your planning position is established, the next step is understanding how a project actually runs from start to finish. The RIBA Plan of Work is the standard framework we use to structure every project — from initial feasibility through to completion. If you'd like to understand what that process looks like in practice, you can read our guide here.
Why Embracing C5 Planning Gives You a Competitive Advantage
The operators who will struggle under C5 are the ones who have been treating holiday letting as a grey area, hoping the rules don't catch up with them. The ones who will thrive are those who get ahead of it: proper consent in place, a well-designed property, a clear planning history. That's a stronger asset, a more defensible business, and a better resale position.
We're a RIBA Chartered Architect practice based in Birmingham, specialising in luxury holiday homes and eco homes. We've helped landowners and investors secure planning approval for projects ranging from off-grid rural cabins to luxury holiday lodges, and we operate our own holiday let, so we understand this from both sides of the process.
If you're at the early stages, considering land, assessing a site, or trying to understand what C5 means for a property you already own, the most useful thing you can do right now is get a clear picture of your planning position before you commit to anything else.
-
In many cases, yes, and the rules are tightening. The common assumption that holiday lets sit outside the planning system is increasingly out of date. Whether you need permission depends on your local authority, your property's current use class, and whether an Article 4 Direction is in place in your area. Getting this wrong isn't just an administrative headache councils can and do issue enforcement notices. Check your position before you commit to anything.
-
It means holiday lets are becoming a formally recognised planning category, separate from ordinary homes. In practical terms, some councils will require you to apply for permission to change a property's use to a short-term let. Others will allow it under permitted development — unless they've opted out. The critical point is that you can no longer assume the rules don't apply to you. Local policy varies significantly, and the direction of travel is toward tighter controls, not looser ones.
-
Current proposals suggest existing legally-operating holiday lets will be automatically reclassified to C5 without a fresh application. But that protection only applies if your let already has the correct consent in place. If it has been operating in a planning grey area, now is the time to address that, before C5 implementation makes it harder to regularise retrospectively.
-
Speak to a specialist before spending money on land, design, or construction. A short feasibility conversation with a RIBA Chartered Architect who knows rural and holiday let planning can tell you what your local authority's position is, whether Article 4 applies to your site, and what planning route is realistic.
