Frequently Asked Questions About Buying Frozen Fish

Where is the best place to buy frozen fish online in the UK?

The best place to buy frozen fish online is from a trusted fishmonger based close to the coast. At Rockfish, we buy directly from the Brixham market each morning and prepare your fish within hours of landing. We don't freeze old stock we can't sell fresh! Our frozen fish is blast frozen as quick as possible from us buying it to ensure the quality is exceptional.

How can I tell if fish bought online is really fresh?

Fresh fish should look bright, firm and glossy with a clean scent of the sea. When you buy from Rockfish, your order is vacuum-packed the same day it’s landed, locking in freshness and ensuring it arrives in perfect condition.

How is frozen fish kept cold during delivery?

We pack all our fish in temperature-controlled boxes made from recycled materials, with ice packs that keep your order fridge-cold for up to 48 hours. Your fish stays perfectly fresh, odour-free and ready to cook or keep in the freezer.

Can I get next-day delivery when I buy fresh fish online?

Yes. Order from Rockfish before 2pm Monday to Thursday, and we’ll deliver your fish nationwide the next day. Orders placed before 12pm on Friday are delivered on Saturday.

Is the fish sustainably sourced?

Absolutely. We source responsibly from Brixham and other South West fisheries that prioritise sustainability and traceability. Many of our species are MSC-certified, and our zero-waste supply chain ensures every fish is used — nothing is thrown away.

Can I put my seafood back in the freezer?

Because our packaging keeps your seafood cold in transit it is perfectly safe to re-freeze when you get it home even if slightly thawed already.

What are the benefits of buying fish direct from the coast?

Buying fish direct from the coast means shorter supply chains, better freshness, and fairer prices for fishermen. At Rockfish, we’re based right on the Brixham quayside, so our fish travels just metres from the boats to our fishmongers before heading to your home.

What types of frozen fish can I buy online?

Our frozen selection doesn't change like our fresh fish as we aim to keep a healthy stock in place for the days the boats can't land. You’ll often find species like hake, monkfish, Dover sole, plaice, brill, and gurnard, along with seasonal shellfish. Every order reflects the rhythm of the sea and what’s at its best that week.

Why choose Rockfish when buying frozen fish online?

We’re more than a fishmonger - we’re part of the South West fishing community. Our team buys directly from the market, prepares each portion by hand, and delivers across the UK the very next day. With Rockfish, you’re not just buying fish; you’re connecting directly to the coast.

Why is Rockfish fish so fresh?
