Who is buying for?

Organisers expecting a busy table

A larger pack may make sense when many visitors or helpers are likely to take biscuits. Tesco lists its 750g pack as five 150g packs, so portions can remain sealed until they are needed; check that the product is available before planning around it.

Buyers with uncertain attendance

A 400g pack or several smaller packs let you open biscuits as demand becomes clearer. Consider how much variety you want alongside custard creams, rather than choosing by total pack weight alone.

People supplying refreshments to others

Keep the original packs accessible for ingredient and allergen checks. If refreshments are being sold or supplied as a food-business activity, ask the relevant local authority which registration requirements apply.

What should you check?

Start with likely demand and the number of packs you would need to open; then check availability, labels and how the biscuits will be supplied.

PriorityWhat to checkYour needs
Pack size Compare pack weights and any stated biscuit counts. Tesco’s 750g pack contains five 150g packs; Crawford’s 300g listing states approximately 26 biscuits. I expect a busy table, but I would rather keep some packs sealed than open everything at the start.
Availability Confirm the listing and stock before relying on a particular format. Tesco marked its 750g pack out of stock in the listing reviewed. Visitor numbers are uncertain, so I need a pack size I can obtain in time for the sale.
Ingredients and allergens Read each pack’s current ingredients and allergen statements. The reviewed standard custard creams list wheat and milk; other declarations differ by product. Other people will take the biscuits, and I want them to be able to check the exact pack rather than rely on a handwritten description.
Storage after opening Check the pack instructions. Sainsbury’s 200g listing specifies a cool, dry place and an airtight container after opening. I may be outdoors for several hours, so I want to open only what I can keep protected and store as directed.
Food-business duties Establish whether selling or supplying refreshments makes the activity a food business. GOV.UK says food businesses operating from temporary premises must register with their local authority; ask that authority how the rule applies to your activity. I plan to sell biscuits, so I need to settle the registration and allergen-information requirements before the event.

What could catch you out?

  • Planning around the largest pack without checking stock

    Tesco’s 750g format provides five separately packed portions, but its reviewed listing marked it out of stock. That matters if you are counting on it for a busy table.

    Confirm availability before the sale and match the quantity you buy to likely demand. Leave the 150g portions sealed until needed.

  • Assuming all custard creams have the same allergen information

    The reviewed standard products list wheat and milk, while other ingredient and cross-contact statements vary. Someone choosing a biscuit needs information for the particular product on the table.

    Keep each original pack accessible and avoid mixing different biscuits in an unlabelled container. Check the physical label, as ingredients can change.

  • Assuming a casual sale is outside food-business rules

    GOV.UK’s Food Standards Agency guidance says food-business registration applies to food sold from temporary premises. Whether a particular car boot sale activity is a food business depends on its circumstances.

    Before selling refreshments, ask the relevant local authority about registration and the food and allergen information required for the way you intend to supply them.

Common questions

How many custard creams should I buy for a car boot sale?

Choose the quantity around expected attendance and whether custard creams are the only biscuits on offer. Tesco’s 750g pack contains five 150g packs that can remain sealed until needed; the other reviewed packs range from 165g to 400g. Check availability before settling on a format.

How should I keep opened biscuits during the sale?

Follow the instructions on the pack you buy and open portions as needed. Sainsbury’s 200g listing says to store the biscuits in a cool, dry place and use an airtight container after opening.

Can I assume standard custard creams suit guests avoiding particular allergens?

No. The reviewed standard Tesco, Crawford’s, Sainsbury’s and M&S products list wheat and milk, and other allergen statements differ between packs. Keep the original packaging available and check its current label rather than assuming products share the same ingredients.

Do I need to register to sell packaged biscuits at a car boot sale?

If your activity is a food business, registration with the relevant local authority is required under GOV.UK Food Standards Agency guidance, including for businesses operating from temporary premises. Ask the authority whether your particular activity meets that definition before trading. Food Standards Scotland says Scottish food businesses must register with their local authority’s environmental health service at least 28 days before opening.

Can I repackage custard creams to sell them individually?

Check the labelling and allergen-information rules for the way you prepare and sell them before repackaging. GOV.UK guidance says prepacked and prepacked-for-direct-sale foods require a food name and full ingredients list with mandated allergens emphasised. Keep the original retail packaging so you can refer to product-specific information.
