For a restaurant, food safety is a hygiene rating: an environmental health officer visits, and you get a score out of five. For a business supplying a supermarket, a wholesaler or a contract caterer, that isn't nearly enough. Your buyer will require a recognised third-party certification, and they'll require it before they'll place an order, not after.
Here's the thing operators discover late: that certification isn't only about your paperwork and your process. It's about the whole environment you produce in. And "the whole environment" is more than the bit where the food is, which is exactly where most people underestimate it.
The standard covers everything, not just the kitchen
This is the single most important thing to understand before you take a unit, because it's the assumption that catches people out.
When you're certified, the audit doesn't stop at the production area. It covers your entire operation. Your changing areas have to be compliant. Your handwashing has to be compliant, in the right places, the right number, the right type. Your staff uniforms and how they're managed have to be compliant. Your welfare facilities, toilets, lockers, the route people take from the door to the production floor, all of it is in scope.
So "is this space audit-ready?" is the wrong question. The right one is "can my whole operation pass, from the changing room to the dispatch door?" A beautiful production area with non-compliant welfare facilities next to it doesn't pass. The standard treats the operation as a single system, and it's only as certifiable as its weakest part.
This is the part that's genuinely hard to solve alone, and easy to inherit from a site that's built for it. More on that below.
The two standards that actually matter
Most UK producers dealing with professional buyers encounter one of two schemes.
SALSA (Safe and Local Supplier Approval) is the one most relevant to the majority of operators. It's a UK scheme built specifically for small and medium producers, run as a non-profit by the Food and Drink Federation, the NFU and UK Hospitality. It's designed to be proportionate and achievable for a growing business, and it's what many supermarkets, wholesalers and contract caterers accept from their suppliers. For most food businesses moving into professional supply, SALSA is the standard that matters.
BRC (the Global Standard for Food Safety) is worth knowing about, but it's probably not your standard. It's a global, GFSI-benchmarked scheme aimed at large-scale manufacturers supplying major retailers at national or international volume. It's more demanding and more expensive, and unless you're operating at that scale, it's likely more than your buyers require. We mention it because people ask, but for the operators we work with, SALSA is almost always the relevant one.
The two aren't rungs on a ladder you climb from one to the other. They're different standards for different situations. The question isn't "which do I progress to?", it's "which does my buyer actually require?", and for most, that's SALSA.
What certification asks of the building
Whichever standard applies, a good deal of what's required is physical, built into the premises rather than written in a manual. HACCP, the documented system that identifies where hazards can enter and controls them, is the backbone of both, but the building has to make those controls possible to operate in the first place.
The recurring physical themes:
Layout and product flow. A clean, one-directional flow from raw materials through to finished product, without raw and ready-to-eat crossing paths. For clients that require it, we build exactly that: a completely circular flow through the unit, with two doors so nothing doubles back on itself. Goods are taken out of their delivery packaging on arrival, washed, and repacked into the operator's own containers, so nothing from the outside world travels into the clean production area. Refuse leaves by its own protected route, so waste never crosses the path of finished product.
Zoning and segregation. High-risk and low-risk activities separated physically, with walls, doors and dedicated areas, not a line on the floor. And, as above, this extends beyond production: a dedicated internal kitchen porter area, and in some cases a second kitchen porter station outside the unit so an operator doesn't share wash-up facilities with anyone. For one contract caterer client we built an entirely separate changing space, with their own lockers and toilet facilities, because their certification required it.
Allergen management. One of the hardest things to control and one auditors scrutinise most closely. Preventing cross-contamination between allergen and non-allergen production is partly procedure, but it's also physical: the segregation, dedicated areas and controlled flow above are what make it provable to an auditor.
Welfare, handwashing and staff flow. This is the "whole operation" point made concrete. Compliant changing areas, correctly specified handwashing, managed uniforms, and a clean route for staff from entrance to production. It's the part operators most often forget to cost, and the part a purpose-built site already has.
Ventilation, surfaces and the fabric of the building. Some clients require their own separate ventilation system, which we've fitted. Alongside that: hygienic wall cladding, the right flooring, drainage that runs the correct way for cleaning and wash-down, and sealed, cleanable surfaces throughout. Exactly the stuff that's expensive and disruptive to retrofit into a unit that wasn't built for it, and straightforward to have from the start.
Why the building decides how hard the audit is
Here's the point a manufacturer weighing where to produce should take away.
You can have an excellent HACCP plan, rigorous procedures and a well-trained team, and still struggle with certification if the premises fight you. If raw and finished product share a corridor, if there's nowhere to properly separate allergen work, if the changing rooms or handwashing aren't compliant, if the surfaces can't be cleaned to standard, then you're either failing findings or spending heavily to physically change the building, welfare facilities and all.
Producing in a space built and maintained to commercial production standard, where the flow, zoning, surfaces and welfare facilities are already right, means the building is helping you pass rather than holding you back. Your certification work becomes about your process and your documentation, which is where it should be.
Here's where we can help, and where we can't. We don't run your certification for you, that's your audit, your HACCP plan, your documentation. What we do is build and adapt the unit to whatever your certification requires, and we've done it repeatedly for clients including McDonald's, Compass Group and Vegan Pattie Lady. If your standard calls for a specific flow, a separate ventilation system, dedicated welfare and changing facilities, or an external goods-in cold store, we make the physical changes needed to achieve it. You bring the standard; we make sure the building can meet it, all of it, not just the kitchen.
What this means if you're scaling towards professional supply
For a producer, where you make your food and which buyers you can win are the same decision, because your buyers won't engage without the certification, and your certification depends in part on your premises, the whole of them.
Starting in a production facility that's already built to standard, welfare and all, lets you reach certification without first having to build or rebuild a fully compliant operation yourself. You prove your product and win the buyer from a space that already clears the bar, then decide whether a dedicated facility is worth it once you know the demand is real. A far less risky order than committing to a build, discovering at audit what it's missing, and paying to put it right.
