Buying fish online in the UK: counter, warehouse or supermarket

There are five realistic ways to buy fish in the UK: a counter in person, a local fishmonger who also delivers, a national online seafood supplier shipping from a packing facility, a supermarket counter and a supermarket chilled or frozen aisle. Each is genuinely better at something and worse at something else. This page sets out the trade-offs plainly so you can pick the right one for the meal you are cooking, rather than looking for a single winner that does not exist.

The five options at a glance

Route	Works well for	Less good at	Typical form
Fishmonger counter, in person	Whole fish you can inspect, cutting to order, advice, unusual species, free preparation	You have to be there, within opening hours	Chilled, cut when you ask
Local fishmonger with delivery	Counter selection and hand cutting, delivered chilled the same day or next day	Limited delivery radius, cut-off times, smaller range than a national warehouse	Chilled, cut to order
National online seafood supplier	Range, availability all year, portion consistency, delivery anywhere in the UK	You cannot see the fish before it is cut, and much of the range arrives frozen	Often frozen or frozen at sea, some chilled
Supermarket counter	Convenience alongside the rest of the shop, some preparation on request	Fewer species, staff availability varies by store and hour	Chilled, some prepared
Supermarket chilled or frozen aisle	Price, predictability, opening hours, no interaction required	Fixed pack sizes and cuts, no advice, no whole fish	Pre-packed chilled or frozen

What do you give up by buying fish online?

Three things, and they are the same three whoever you order from.

• You cannot judge the fish yourself. Eyes, gills, flesh and smell are the checks a buyer uses, and none of them survive a photograph. You are buying the supplier's judgement rather than your own.
• You choose before you know what is good. On a slab you switch to the fish that came in well this morning. Online you order what the site listed when you clicked.
• The cut is decided in advance. A pack is one thickness and one weight. If your recipe wants a thick shoulder piece or four equal portions off one fish, that is a conversation rather than a checkbox.

What do you gain by buying fish online?

• It arrives. No trip, no opening hours and no carrying a cool bag across town.
• Range and availability. A national supplier holds species that no single counter can stock every day, and holds them all year, because freezing removes the season.
• Consistency. Fixed portion weights mean fixed cooking times, which matters for weeknight cooking and for batch cooking.
• Stock control. A freezer means you cook fish when you want to rather than when it is about to turn, which is the main reason households eat more fish than they otherwise would.
• Reach. If you do not live near a fish counter, online is the option that exists. Hundreds of high streets have lost theirs.

Is fish delivered from a warehouse worse than counter fish?

No. It is different. Fish frozen quickly at sea and shipped frozen can be in better condition on arrival than a chilled fillet that has spent days in transit, because freezing stops the clock. What you are trading is choice rather than quality: the form of the fish, the cut and the ability to assess it yourself. Our page on fresh or frozen fish goes through the physics of that in detail.

The fair way to compare is by question rather than by category. Ask any seller, online or in person: when did this come in, has it been frozen and when, is it whole or already cut and where was it caught or farmed. Any route can answer those well. Any route can answer them badly.

How much does each option cost?

Direct price comparison is harder than it looks, for three reasons, and understanding them saves more money than chasing a headline price.

• Whole weight against edible weight. A whole fish is priced on its full weight and a round fish typically yields roughly 40 to 50 per cent of that as skin-on fillet. A packed fillet is already all edible. A whole fish that looks dearer per kilo can work out level once you account for this, and you also leave with bones for stock.
• Delivery and minimum orders. National delivery of chilled or frozen goods carries a real cost, usually recovered through a carriage charge or a minimum spend. Factor that into the per-kilo figure on a small order.
• Preparation. Filleting, skinning, pin-boning, shucking and crab picking are typically free at an independent counter and are a priced processing step in a packed product.

Cheaper species close the gap faster than any route does. Gurnard, coley, whiting, dabs, megrim, mackerel and mussels are inexpensive everywhere and cook beautifully.

Which should I choose?

• Cooking tonight or tomorrow, and you live near a counter. Buy chilled in person. You get to choose by eye and have it cut for the dish.
• A whole fish, a whole crab, oysters or anything you want prepared a specific way. A counter, in person or by phone. This is the thing a warehouse cannot do.
• Stocking up for the month, or you want the same portion every time. A national online supplier, frozen.
• No fish counter within reach. Online, and choose frozen at sea for white fish rather than chilled shipped long distances.
• A dinner for eight next Saturday. Order ahead from a counter that buys to order. Volume and specific species are planned at market days in advance.
• Weeknight, low effort, tight budget. The supermarket aisle is a reasonable answer and there is no shame in it. Frozen white fish fillets from a big retailer are a decent product.
• You want to learn about fish. A counter. The conversation is the part you cannot buy online.

What should I check before ordering fish online?

• Chilled or frozen on arrival. Say which you are getting, since it changes how you plan the week.
• Delivery days and cut-off times. Chilled seafood usually ships on specific days and will not sit over a weekend.
• Who is in for the delivery. A chilled box left on a doorstep in July is a wasted order. Look for a timed slot or a safe place option.
• Packaging and coolant. Wool or recycled liners and gel packs are standard. Check what you have to dispose of.
• Whether it is cut to order or pre-packed. Ask if the site does not say.
• Catch or farm origin and method. Good sellers publish it.
• What happens if it arrives warm or late. Read the policy before you need it.
• The food hygiene rating of the premises it ships from. Ratings for UK food businesses are public on the Food Standards Agency register.

Where From The Sea fits

We are the first option and the second. We have run a counter on Barnes High Street since 1972, we buy at Billingsgate through the week and direct from Cornwall, and everything is cut by hand in the shop. We deliver locally around Barnes, Mortlake, East Sheen, Kew, Richmond, Putney and Chiswick, and we ship nationally. We hold a Food Hygiene Rating of 5 and a 4.8 average from 82 Google reviews. If you want a whole fish filleted a particular way, or six crabs dressed for Saturday, ring the shop or use special orders. If you want a freezer full of consistent portions, a national frozen supplier will serve you better than we will, and we would rather say so.
