Online Fish Shop London
Fresh fish, hand-picked at Billingsgate Market and delivered to your door across London. House O Fish is a family-run online fishmonger built on one idea: genuine market freshness, chosen by hand and prepared just for you — not bulk-bought, shrink-wrapped and left to sit.
Browse the shop, or order the personal way — message us on WhatsApp, tell us what you’d like and how to prepare it, and we’ll bring it to you fresh. This is what an online fish shop in London should feel like.
Why buy fish online
Why Buy Fish Online
Buying fish online from a specialist isn’t a compromise — done right, it’s fresher and more convenient than the supermarket. Here’s why our customers make the switch.
Fresh fish without leaving home
A great fishmonger used to mean a trip across town. Our online fish shop brings that same hand-picked, market-fresh quality straight to your door across London — no queues, no compromise.
Hand-selected, not warehouse-picked
We don’t pull stock from a cold store. Every order is chosen by hand at Billingsgate Market on the day, so you get fish at its genuine peak rather than whatever was packed days ago.
Order the way that suits you
Browse the shop online, or simply message us on WhatsApp and tell us what you’d like. It’s a personal service — real people who know fish, ready to help you choose and prepare it.
Prepared exactly how you want
Gutted, scaled, filleted or whole — we prepare your fish to order before it’s packed, so it arrives ready for the pan, the oven or the grill.
Cold-packed, delivered fresh
Your order is cold-packed to hold it in peak condition and delivered fresh across London the same week. Market quality, at your door.
Freshness over mass production
We’re a family-run fishmonger that buys what’s genuinely good, not whatever fills a shelf. That focus on freshness is the whole point of buying from us.
Fresh vs Supermarket Fish
Supermarket fish is bought in large volumes through long supply chains, and can be several days old by the time it reaches the shelf — pre-packed, often previously frozen, and chosen by no one in particular.
Our fish is hand-selected at Billingsgate the same week it’s delivered, checked individually for quality, prepared to order and cold-packed fresh. The difference in flavour, texture and freshness is immediate — and once you’ve tasted it, it’s hard to go back.
The House O Fish difference
Everything we do is built around freshness and a genuine, personal service.
How WhatsApp ordering works
Ordering, Made Personal
No clunky checkout, no waiting on hold. Ordering from House O Fish is a quick, friendly conversation — here’s how it works.
Join the WhatsApp group
Tap to join our WhatsApp community — it’s where we post the weekly catch list and where ordering happens. No app to learn, no account to create.
See the weekly catch
Each week we share what we’re bringing back from Billingsgate. You see exactly what’s fresh and available before you order.
Send your order
Message us with what you’d like and how you’d like it prepared — whole, filleted, scaled, gutted. Ask us anything; we’re happy to advise.
We hand-pick & deliver
We select your fish at the market on Saturday morning, prepare it, cold-pack it and deliver it fresh across London. Order by Wednesday midnight for Saturday delivery.
Quality & preparation
Premium Fish, Prepared Your Way
We specialise in premium whole fish and traditional seafood, prepared exactly how you need it.
Premium & whole fish
Sea bass, sea bream, bonito, bluefish, turbot, red mullet, sardines, anchovies and more — traditional and Mediterranean favourites at their freshest.
Prepared to order
Tell us how you’d like it: whole, gutted, scaled, filleted, butterflied. We prepare everything before packing so it’s ready to cook.
Checked by hand
Every fish is inspected for freshness at the market. If it isn’t right that morning, we don’t buy it — simple as that.
Delivered cold & fresh
Cold-packed and delivered across London the same week, so it arrives in the condition it left the market in.

What our customers say
Real Customers, Real Seafood
We let the fish — and the people who cook it — do the talking.
“The freshest I’ve found in London”
Our customers tell us our fish tastes noticeably fresher than anything they’ve had from the supermarket — and they love being able to ask for exactly the cut and preparation they want.
A loyal community
Many of our customers order week after week through our WhatsApp group, and share photos of what they’ve cooked. See real customer dishes in our Behind The Catch gallery.
We’re proud of our reviews — and we’d rather show you real fish, real kitchens and real customers than make claims we can’t back up.
A quick buying guide
How To Choose Your Fish
Not sure what to order? A few simple pointers — and remember, you can always just ask us on WhatsApp.
For the grill or BBQ
Oily fish shine over fire: sardines, bluefish (lüfer), bonito (palamut) and mackerel. Whole sea bass and bream are superb on the BBQ too.
For a centrepiece
Roast a whole turbot (kalkan) or a large sea bass whole on the bone for a showstopping, low-effort centrepiece that feeds the table.
For everyday cooking
Sea bass, sea bream and mackerel are quick, versatile and forgiving — perfect for midweek meals the whole family will enjoy.
For entertaining
Mix whole fish with shellfish like prawns and mussels for a generous, sociable spread. Tell us your plans and we’ll help you choose.

Supermarket fish is bought in bulk and can be several days old by the time it’s on the shelf. We buy the same week we deliver, hand-pick each fish at the market, and prepare it to order — so it reaches you genuinely fresh, not pre-packed days earlier.
