Regular home-lunch planners
If tuna features in several weekly sandwiches, salads, jacket potatoes or pasta lunches, the drained amount per tin and the number of tins matter more than the headline pack weight.
Who these packs suit
Short-break convenience buyers
A no-drain format removes the draining step when lunch has to fit between meetings. John West describes its named No Drain Tuna Chunks in Spring Water range as ready to open and eat.
Shoppers checking seafood sourcing
If certification or a stated catch method influences your choice, look for the claim on the particular pack. Tesco Groceries and Sainsbury's publish product-specific sourcing statements for some tuna multipacks.
What matters when choosing
For working-from-home lunches, start with the need that most affects your purchase, then check the exact tin and pack details.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable quantity | Compare tin count and drained grams per tin; net weight includes packing liquid. | If I make tuna lunches repeatedly, I need enough drained tuna in each tin without opening more than the meal calls for. About 33% of consumers would put usable quantity first. |
| Preparation time | Check for an explicit no-drain designation, then compare the pack count with conventional tins. | On a short break between meetings, I want to add tuna to lunch without draining it. That would be the primary need for about 27% of consumers. |
| Packing liquid and label | Read the exact variant's ingredients and salt value per 100g drained. | When choosing tuna for my usual sandwiches or salads, I want the packing liquid and nutrition label to suit that meal. About 20% of consumers would make this their main consideration. |
| Seafood sourcing | Look for an MSC label or a specific sourcing statement on the pack you intend to buy. | If a sourcing claim guides my purchase, I need it to apply to this tin rather than to the brand generally. Checking that claim would come first for about 20% of consumers. |
Buying pitfalls
-
Comparing only the weight printed on the front
Net weight includes packing liquid. Tesco Groceries lists its 4 × 145g spring-water pack as 4 × 102g drained, and its Princes listing gives the same drained quantity for that named 4 × 145g pack.
Compare drained grams per tin and across the whole multipack when assessing how many lunches it will cover.
-
Assuming a brand's variants have identical labels
Packing liquid, salt values and sourcing statements belong to specific products. For example, Tesco Groceries lists 0.90g salt per 100g drained for its named spring-water four-pack, while Sainsbury's lists 0.42g per 100g drained for its named brine four-pack.
Read the ingredients, nutrition panel and any certification statement on the exact variant and pack size you choose.
-
Opening more tuna than one lunch needs
Once a tin is open, its storage instructions affect when leftovers can be used. The named Tesco, Princes and M&S products specify use within two days after refrigeration; the named Sainsbury's brine pack specifies one day.
Choose a tin size that fits your meal, or plan the next use around the instructions on your pack.
-
Letting a bulk purchase set the weekly menu
The Food Standards Agency restates NHS tuna-consumption guidance for people who are pregnant or trying for a baby. Having more tins in the cupboard does not change that guidance.
If it applies to you, plan around no more than four medium cans of tuna a week or two tuna steaks a week, as stated by the Food Standards Agency.

John West describes its No Drain Tuna Chunks in Spring Water MSC three-pack as a format that can be opened without draining.

Princes Food and Drinks lists spring-water tuna chunks in single tins and three-, four-, six- and eight-tin formats.
- The listed formats offer several tin counts for different lunch routines.

Common questions
How can I compare the amount of tuna in two multipacks?
Compare their drained weights and tin counts, not just the net weights on the front. Tesco Groceries, for example, lists its spring-water 4 × 145g pack as 4 × 102g drained; a differently sized or no-drain pack needs its own quantity check.
What should I do with tuna left after opening a tin?
Transfer leftovers to a non-metallic container, refrigerate them and follow the instruction on your pack. The named Tesco, Princes and M&S products specify use within two days; the named Sainsbury's brine pack specifies one day.
Can I stock up on tuna while pregnant or trying for a baby?
You can buy a multipack, but plan how often you eat it. The Food Standards Agency restates NHS guidance for people who are pregnant or trying for a baby: no more than four medium cans of tuna a week or two tuna steaks a week. Its medium-can reference is approximately 140g drained.
Does an MSC claim apply to every tuna tin from a brand?
No; check the claim on the exact pack. Tesco Groceries and Sainsbury's give sourcing statements for named multipacks, but those statements should not be extended to other packing liquids, tin sizes or unlabelled variants.
