Seafood for restaurants demands more structure than almost any other ingredient category. Fish and shellfish have tight freshness windows, variable seasonal availability, and species that simply cannot be sourced at short notice. A clear weekly routine — built around honest communication with your supplier — is what keeps your menu consistent and your kitchen out of trouble.
Key Takeaways
- Structure your weekly seafood order around your confirmed supplier cut-off times and delivery schedule.
- Split your order across fresh, frozen, and smoked lines to maintain menu flexibility.
- Confirm portioning, minimum order quantities, and lead times directly with your supplier before placing standing orders.
- Check receiving arrangements — temperature, documentation, and labelling — every delivery.
- A clear, detailed enquiry speeds up onboarding with any wholesale seafood supplier.
What Is Seafood for Restaurants?
In procurement terms, seafood for restaurants means wholesale-grade fish, shellfish, cephalopods, roe, and prepared seafood sourced from a trade supplier rather than a retail fishmonger. The key differences are volume, specification, and consistency.
A retail customer buys what is on the counter that day. A restaurant buyer agrees on species, cut, weight range, and delivery schedule in advance. That means your fresh fish range can arrive portioned and labelled to your kitchen's specification, reducing prep time and waste.
Wholesale suppliers also carry lines that retail counters rarely stock — such as whole turbot, monkfish fillet, caviar, and raw octopus. For a serious kitchen, wholesale access opens up the full menu.
How Restaurant Seafood Ordering Works
Most wholesale suppliers work on a standing-order model with scope to adjust each week. You agree a baseline — for example, a set volume of Scottish salmon fillet and sea bass fillet per delivery — then confirm any changes before your supplier's cut-off time.
Cut-off times and delivery windows vary by supplier and location. Always confirm these details when you onboard, and check whether your postcode or access arrangements affect what is possible. Individual wholesale markets also publish their own trading arrangements; if you are considering a market-based supplier, Billingsgate Market publishes its own information for buyers — check directly rather than assuming universal rules apply.
Communication is the most underrated part of the process. A supplier who can flag a shortfall on a particular species — or alert you to an unexpected catch of line-caught Dover sole — gives your kitchen a genuine edge over menus built on guesswork.
Your Practical Weekly Ordering Checklist
Use this checklist at the start of each ordering cycle. Volumes will depend on your covers, service days, and storage capacity. Treat all quantities and availability as things to confirm with your supplier each week.
Fresh Fish
- White fish fillets: Scottish cod, hake, plaice fillet, lemon sole
- Oily fish: mackerel, sardines, bonito
- Premium whole fish: sea bass whole, sea bream whole, turbot, halibut
- Speciality: red mullet, skate wings, black cod
Shellfish
- Bivalves: fresh mussels, fresh clams, scallops in shell, oysters
- Crustaceans: fresh prawns, live crab, live lobster
Frozen Lines to Top Up
- Raw peeled IQF prawns — check stock before every order; these move fast
- Frozen monkfish fillet — useful buffer when fresh supply is tight
- Squid tubes and baby squid
- Frozen raw octopus for slow-cook prep
- Prepared items: salt and pepper calamari, breaded butterfly prawns, garlic marinated prawns
Smoked and Prepared
- Smoked salmon — check par levels; this moves quickly at brunches and on starter menus
- Smoked haddock fillet
- Smoked mackerel fillet
Roe and Garnishes
Planning Deliveries and Receiving Arrangements
Delivery frequency — whether one, two, or three drops per week — depends on your storage capacity, your menu's fresh fish turnover, and what your supplier can support. Confirm this before you set a standing schedule. Frozen lines generally need topping up less often, but check par levels weekly to avoid running short at busy periods.
When deliveries arrive, check every box. Look for correct core temperature, clear species and weight labelling, and any accompanying documentation your supplier provides. Good receiving practice is the last line of defence before product reaches your kitchen, and it is worth agreeing the process — including returns and substitutions — with your supplier upfront.
How to Submit a Wholesale Seafood Enquiry
A clear, specific enquiry saves time on both sides. Before contacting a seafood supplier London kitchens rely on, have the following ready:
- Species list — the fish and shellfish you need regularly, with preferred cut (fillet, whole, portion)
- Weekly volumes — approximate kg per species rather than just cover counts
- Delivery frequency — how many drops per week and your preferred days
- Postcode and access notes — loading bay details, time restrictions, refrigerated storage capacity
- Frozen and prepared requirements — list any frozen or value-added lines you currently source elsewhere
Browse the full product range before getting in touch so your enquiry is as specific as possible.

Frequently asked questions
What species and cuts should a restaurant order for a flexible menu?
The most versatile fresh lines tend to be white fish fillets such as cod, hake, and plaice, alongside whole fish like sea bass and sea bream for table-side presentation. Shellfish including mussels, scallops, and prawns cover a wide range of dishes. The right mix depends on your menu style — discuss specific cuts and weight ranges with your supplier when setting up your account.
How do I work out the right weekly volumes for my kitchen?
Start from your expected covers and the number of dishes each line appears on, then add a modest buffer for unplanned demand. Suppliers can help you calibrate this once they know your service pattern. It is generally better to begin conservatively and increase gradually than to over-order and manage waste.
What lead times should I expect from a wholesale seafood supplier?
Lead times vary by supplier, species, and your location. Some suppliers offer next-day delivery for orders placed by a confirmed cut-off time; others require more notice for certain species or minimum volumes. Always confirm the exact cut-off time and lead time with your supplier before finalising your ordering schedule.
How should I set up receiving arrangements for seafood deliveries?
Agree a receiving process with your supplier before the first delivery. This should cover expected core temperatures, labelling requirements, acceptable species substitutions, and a clear returns or shortfall procedure. Checking every delivery on arrival protects your kitchen and makes it easier to resolve any issues quickly.
What information should I include in a wholesale seafood enquiry?
Include a species list with preferred cuts, estimated weekly volumes in kg, delivery frequency and preferred days, your delivery postcode and any access restrictions, and a note on whether you need frozen or prepared lines. The more specific your enquiry, the faster a supplier can respond with accurate pricing and availability.
What is the difference between fresh and frozen seafood for restaurant use?
Fresh lines offer the texture and flexibility that premium dishes often require, but they need careful stock management and more frequent deliveries. Frozen lines — particularly IQF prawns, squid, and octopus — provide a reliable buffer stock that reduces waste and simplifies ordering. Many kitchens use both: fresh for centrepiece dishes, frozen for sauces, garnishes, and high-volume items.
