The trouble is that “do I need a licence” has no general answer. It depends on what you do, where you do it, and occasionally on who you employ. This is a guide to working out which category you fall into, what the process actually involves, and the one situation nobody warns you about: sectors where the licence exists, you meet every requirement, and you still cannot have one.
Start with the licence finder, not with Google
The government maintains a licence finder on GOV.UK. You enter your activity and your postcode, and it returns the permissions that apply and the authority that issues them.
Use it first, because the answer is frequently counterintuitive. Licensing in the UK is fragmented across local authorities, the Environment Agency, the Food Standards Agency, the Security Industry Authority and several sector regulators, and the same business can sit under three of them at once. A cafe that sells wine, plays recorded music and puts tables on the pavement is dealing with three separate permissions from two different bodies.
Most small business licences are issued by your local council, which means the fee, the processing time and occasionally the conditions vary by postcode. Two identical businesses in neighbouring boroughs can face different costs.
The permissions small businesses hit most often
Food. If you handle, prepare, store or serve food, you must register the premises with your local authority at least 28 days before you start trading. Registration is free and it cannot be refused. That last point matters: this is a notification regime rather than a gatekeeping one. What follows is inspection, and your hygiene rating is the thing that carries commercial consequences.
Alcohol. Selling alcohol needs two things, and people routinely confuse them. The venue needs a premises licence. Separately, a named individual needs a personal licence, and that person must be designated as the premises supervisor. One without the other does not work. Fees are set by band rather than flat rate, so check with the licensing team before budgeting.
Waste. If you carry, transport or dispose of waste as part of your business, including a builder taking rubble off site, you need to register as a waste carrier with the Environment Agency. This one catches a lot of trades who assume it applies only to waste companies.
Security staff. Door supervisors, guards and several related roles need individual Security Industry Authority licences. The obligation sits with the individual, but the liability for using unlicensed staff sits with you.
Street trading, taxis and private hire, scrap metal, animal boarding, houses in multiple occupation. Each has its own regime, each is administered locally, and each has its own renewal cycle.
What a licence actually costs
The application fee is rarely the real cost. Three other things matter more when you are planning.
Time. Some permissions are effectively instant. Others involve a consultation period during which neighbours, police or the local authority can object, and that period cannot be compressed by paying more.
Conditions. A licence frequently arrives with obligations attached: opening hours, staffing levels, record keeping, signage, CCTV. Those are operating costs, and they persist for as long as the licence does.
Renewal and variation. A licence is a standing relationship with a regulator, not a one-off purchase. Changing what you do, where you do it or who supervises it usually means varying the licence, which is its own process.
The sectors where the answer is simply no
Everything above assumes that if you satisfy the criteria, you get the licence. For most regulated activities in the UK that holds.
It does not hold everywhere, and the clearest illustration in Europe is Belgian gambling, where the number of licences is fixed in law rather than set by demand.
Belgium allows nine casino licences nationally, 180 gaming arcade licences and 30 betting operator licences. As of October 2025, almost all of them were already held. There is no queue and no process for issuing the tenth casino licence, because the tenth does not exist.
The structure goes further. Online permissions in Belgium are not standalone. An A plus licence is the online extension of a casino licence, a B plus extends a gaming arcade licence, and an F plus one extends a betting licence. Without the underlying land-based licence, the online extension cannot be obtained at all. An operator such as madisoncasino.be runs online under licence B plus 3320 precisely because a class B land-based licence sits underneath it.
The practical consequence for anyone looking at that market is that entry happens through acquiring a company that already holds a licence, not through applying for one. The licence has become an asset with a market value of its own, entirely detached from the application fee.
What the running costs look like when the regulator bills you
Belgium is also a useful example of a model that appears in several regulated sectors: the regulator is funded entirely by the businesses it supervises.
Annual contributions there run from 865 euros for a class C licence to 25,398 euros for a class A casino, plus 821 euros for each gaming machine. Holders of A plus, B and B plus licences pay 12,698 euros a year. Those figures rose 15 percent for 2026, having been unchanged since 2018, to close a funding gap against a regulator spending ceiling of 9.18 million euros.
That is worth noticing if you operate in any sector with a self-funded regulator. Your compliance costs are not driven by your own activity alone. They move with the regulator’s budget, and you have very little influence over it.
Three questions before you commit
Check the licence finder for every activity you intend to carry out, not just the main one. Businesses get caught by the secondary activity, the music, the pavement tables, the waste.
Ask the issuing authority about processing time in writing, and build it into your opening date rather than hoping.
And in any heavily regulated sector, establish early whether licences are issued on merit or capped in number. The difference determines whether your entry plan is an application or an acquisition, and those are not the same business case.
