What the law requires a mobile food unit to contain
21 requirements across the six chapters of Annex II that reach a trailer, each mapped to the physical thing it asks for.
The chapter written for movable premises is nine short paragraphs, and the brevity gets read as permission. What happened is that two chapters were lifted off and the rest were not, so equipment, waste, water, personal hygiene and training bind a trailer exactly as they bind a restaurant. That is where the specific obligations are.
Paraphrased from Annex II as it has effect in Great Britain, read 2026-09-07, with every chapter and paragraph named so it can be checked rather than believed.

What makes it binding
An article, a registration and an offence
The annex on its own is a list. These three turn it into a duty, a record and a penalty.
| Article 4(2) | The obligation A food business operator carrying out any stage after primary production must comply with the general hygiene requirements laid down in Annex II. This is the article that makes the annex binding rather than advisory. |
|---|---|
| Article 6(2) | Registration Every food business operator must notify the competent authority of each establishment under its control, with a view to registration. The Food Standards Agency asks for that at least 28 days before trading in England, Wales and Northern Ireland, and registration cannot be refused. |
| Regulation 19(1), SI 2013/2996 | The offence In England, contravening a specified provision is a criminal offence. On summary conviction the penalty is a fine not exceeding the statutory maximum; on conviction on indictment, imprisonment for up to two years, a fine, or both. Scotland, Wales and Northern Ireland have their own instruments to the same effect. |
Read the headings first
Chapter III is short because two chapters were lifted off, not because less is required
Chapter I sets the general requirements for food premises and its heading excludes premises specified in Chapter III. Chapter II sets the requirements for rooms where food is prepared and excludes them too. So a mobile unit does not have to satisfy those two, and Chapter III replaces them with nine paragraphs written in terms of what is necessary rather than what must be installed.
Nothing lifts the rest. Chapter IV on transport, Chapter V on equipment, Chapter VI on food waste, Chapter VII on water supply, Chapter VIII on personal hygiene and Chapter XII on training carry no exclusion for movable premises, so they apply to a trailer exactly as they apply to a restaurant. Those chapters are where the specific obligations live, and they are the ones a unit is built to satisfy or fails to.
This is checkable in one click rather than taken on trust, which is the only reason it is worth writing down: read the two headings and the absence of an exclusion on the others.
The six chapters that reach a trailer
21 requirements, and what each asks a unit to have
Movable and temporary premises
Chapter IIIThe chapter written for a trailer. Nine paragraphs, each qualified by what is reasonably practicable or necessary, which puts the burden on the operator to justify the choice rather than on the regulation to specify it.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1: sited, designed, constructed, kept clean and in good repair so as to avoid contamination, in particular by animals and pests, so far as is reasonably practicable | Sealed penetrations, no open cavity a rodent can occupy, and a floor to wall junction that can be cleaned rather than one that hides. Most of this is decided at build and cannot be added later |
| Paragraph 2(a): appropriate facilities for personal hygiene, including hygienic hand washing and drying, sanitary arrangements and changing facilities, where necessary | A dedicated hand wash basin that is not the food preparation sink, with hot water at it, plus a way to dry hands that does not reuse a cloth. Whether sanitary and changing facilities are needed in the unit depends on what else the pitch provides |
| Paragraph 2(b): food contact surfaces in sound condition, easy to clean and where necessary to disinfect, which requires smooth, washable, corrosion resistant and non toxic materials unless the operator can satisfy the authority otherwise | Stainless steel of a stated grade, welded or sealed at every joint. The alternative route exists but it puts the operator in front of an environmental health officer arguing about a material, which is a poor position to design into a unit |
| Paragraph 2(c): adequate provision for cleaning and where necessary disinfecting working utensils and equipment | A wash up facility sized for the largest thing that has to go in it, which is a specification question about the pans rather than about the sink |
| Paragraph 2(d): where food is cleaned as part of the operation, adequate provision to do it hygienically | A separate food wash sink where the menu involves washing produce, because the same bowl cannot be the hand wash, the wash up and the food wash |
| Paragraph 2(e): an adequate supply of hot and cold potable water | Tank capacity that matches the service length, a water heater sized to keep up rather than to pass a test, and a tank that can be drained and disinfected |
| Paragraph 2(f): adequate arrangements or facilities for the hygienic storage and disposal of hazardous or inedible substances and waste, liquid or solid | A sealed waste water tank of at least the capacity of the fresh water tank, and a covered waste container that has somewhere to live that is not the floor of the serving area |
| Paragraph 2(g): adequate facilities or arrangements for maintaining and monitoring suitable food temperature conditions | Refrigeration rated for the ambient the unit works in rather than for a showroom, and a thermometer that is read and recorded. The monitoring half is as binding as the maintaining half |
| Paragraph 2(h): foodstuffs placed so as to avoid contamination so far as is reasonably practicable | Storage that separates raw and ready to eat by position rather than by intention, which is a layout decision at build |
Equipment
Chapter VNot disapplied for movable premises. It binds every article, fitting and piece of equipment that food touches.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1(a) to (c): equipment food touches is to be effectively cleaned and where necessary disinfected, and constructed of such materials and kept in such condition as to minimise contamination risk | Equipment specified with a food contact material declaration rather than assumed, because the declaration is the evidence and it is asked for at inspection |
| Paragraph 1(d): installed so as to allow adequate cleaning of the equipment and the surrounding area | Clearance behind and beneath appliances, or sealed to the surface. The gap that cannot be reached is the one an officer looks for |
| Paragraph 2: fitted with appropriate control devices where necessary | Thermostats, cut outs and interlocks specified as part of the appliance rather than added as a fix |
Food waste
Chapter VINot disapplied. Three of its four paragraphs are about the container and the storage rather than about the collection.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1: waste is removed from rooms where food is present as quickly as possible so it does not accumulate | Somewhere for it to go that is not the food room, which in a trailer means a designed external or sealed position rather than a bin by the door |
| Paragraph 2: waste is deposited in closable containers of appropriate construction, in sound condition, easy to clean and where necessary to disinfect | A lidded container that survives being washed out, secured so it does not move in transit |
| Paragraph 3: adequate provision for the storage and disposal of waste, with stores kept clean and free of animals and pests | Capacity matched to the service length, because a container that fills halfway through the day produces the accumulation paragraph 1 prohibits |
Water supply
Chapter VIINot disapplied, and the paragraph most often misread. Potable is a legal standard, not a description of a tank.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1(a): an adequate supply of potable water, used whenever necessary to ensure food is not contaminated | A tank, hose and fittings all rated for potable water, and a filling procedure that does not undo it. A food grade tank fed through a garden hose is not a potable supply |
| Paragraph 2: non potable water, where used, circulates in a separate identified system that cannot connect with or reflux into the potable system | Physical separation and an air gap rather than a valve, because a valve is a procedure and the regulation asks for a system |
| Paragraph 4: ice that touches food or may contaminate it is made from potable water and stored so it is protected from contamination | An ice machine plumbed to the potable side, which decides where it can be positioned |
Personal hygiene
Chapter VIIINot disapplied. It is written about people, and two of its consequences are physical.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1: every person working in a food handling area maintains a high degree of personal cleanliness and wears suitable, clean and where necessary protective clothing | Somewhere to change and somewhere to put outdoor clothing that is not the food area, which is a space allocation made at build or not at all |
| Paragraph 2: a person suffering from or carrying a disease likely to be transmitted through food is not permitted to handle food, and must report it | A management obligation rather than a build one, and the reason a unit with one operator needs a plan for the day that operator is ill |
Training
Chapter XIINot disapplied, and one line long.
| What the instrument requires | What that means in a towable unit |
|---|---|
| Paragraph 1: food handlers are supervised and instructed or trained in food hygiene matters commensurate with their work | No level of qualification is named in the regulation. The level asked for in practice comes from the local authority and from the food safety management system, not from this paragraph |
Almost no numbers
There are almost no numbers in it, and that is the difficulty
Annex II gives one measurable requirement for a mobile unit and it is not a dimension: water must be potable. Everything else is adequate, appropriate, suitable, sufficient or so far as is reasonably practicable. There is no litre figure for a water tank, no square metre for a serving area, no count of sinks.
That is deliberate, because the annex covers a marquee, a market stall, a vending machine and a trailer with the same words. It also means a buyer comparing two units cannot read compliance off a specification sheet, and a supplier can call almost anything compliant without saying anything false.
So the useful question is not whether a unit is compliant, which is a claim about a business rather than about a trailer. It is whether each requirement above has a specific physical answer in the drawing, and whether the evidence for it exists on paper before the unit is built. That is what the second column is for.

Set this as an exercise
Environmental health, hospitality business- Chapter I and Chapter II both exclude premises specified in Chapter III. Chapters IV to XII carry no such exclusion. Set a student to find that in the headings and say what it means for a trailer, and why the brevity of Chapter III is not permission.
- Annex II gives one measurable requirement for a mobile unit and it is not a dimension. Identify it, then explain why a buyer comparing two units on a specification sheet cannot read compliance off it.
- Take one paragraph of Chapter III, 2(f) on hazardous and inedible waste for instance, and specify the physical answer for a unit serving 200 covers over a six hour service. State what you had to assume and why the regulation does not tell you.

Three things outside this reference
This is Great Britain. Northern Ireland applies the EU version of 852/2004 under the Windsor Framework, and while Annex II reads the same today, it is a different instrument and can diverge.
Gas, electrical safety and street trading consent are separate regimes with separate enforcement and none of them appears in this regulation. Passing an inspection under this annex says nothing about them.
This is not legal advice and it is not a substitute for reading Annex II. Where a paraphrase and the instrument disagree, the instrument is right. Tell us and it is corrected.
What a unit has to satisfy to be registered as a vehicle is a separate question, answered on registration by country. What the law asks of a welfare unit on a construction site is on welfare facilities under CDM 2015.
