For custard creams during revision breaks, compare listed total sugars per 100 g first, then sugars per biscuit for the amount you plan to eat. Among the checked packs, Sainsbury's lists 26.5 g per 100 g but marks its 200 g pack out of stock; Tesco lists 28.3 g per 100 g for its 400 g pack. A lower figure in this comparison is not a verified ‘reduced sugars’ claim, and a different snack may better fit a plan to have sugary foods less often.
If you want custard creams for a break, the per-100 g figure helps you compare packs on the same basis. The per-biscuit figure helps you consider the amount you intend to eat; neither figure alone establishes a ‘reduced sugars’ claim.
If you expect to snack repeatedly, consider whether biscuits fit that plan or whether you would rather choose a different type of snack for some breaks. The NHS advises keeping both the frequency and amount of sugary foods and drinks as low as possible.
Food bought for a school to provide to pupils raises a different question from a personal revision snack. Check the school-food framework for the relevant UK nation and the circumstances in which the food will be provided.
Use the per-100 g figure to compare packs, then consider the biscuit, the portion and how often it will be part of a revision break.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars on the label | Compare total sugars in g per 100 g, not figures for different serving sizes. For an intended portion, check sugars per biscuit as well; the current pack label is the final reference. | I want to compare custard creams without mistaking a relatively lower listed figure for a verified ‘reduced sugars’ claim. |
| Snack frequency | Consider how often biscuits would feature in revision breaks. The NHS advises keeping the frequency and amount of sugary foods and drinks as low as possible; the British Nutrition Foundation also identifies fresh fruit and wholegrain crackers as alternative snacks. | For several breaks in a day, I may want something other than custard creams for some of them. |
| Ingredients | Read the delivered pack’s ingredient, allergen and precautionary statements, especially if the biscuits will be shared. Online product information can change. | Before sharing a pack, I need to know whether its current label is suitable for the person who will eat it. |
| Pack and variant | Check the pack size, exact biscuit variant and availability when ordering. Compare each variant using its own nutrition panel. | I want the pack I can order to match the one whose sugar figures I compared. |
The lowest total-sugars value among a few checked packs does not establish that a product carries a substantiated comparative nutrition claim.
Describe the difference as a comparison of listed g per 100 g values, and check the product’s own labelling before relying on a ‘reduced sugars’ claim.
Tesco lists 28.3 g sugars per 100 g and Asda lists 29 g per 100 g for the checked packs, while both list 3.4 g per biscuit. Different measures answer different questions.
Use g per 100 g for a like-for-like pack comparison, then per-biscuit information for the number you expect to eat.
A useful nutrition comparison does not confirm that the same pack is available to order or that its current ingredients are unchanged.
Confirm the exact variant and availability when ordering, and read the delivered pack before eating or sharing it.
These figures describe particular listed packs, not every custard cream sold under each brand.
Tesco Custard Cream Biscuits are listed in a 400 g pack.
Sainsbury's Custard Creams are listed in a 200 g pack.
Asda Custard Creams are listed in a 400 g pack.
McVitie's Tasties Custard Creams are a named 300 g biscuit pack.
Crawford's Custard Creams are listed in a 300 g pack at Tesco.
M&S Extra Cream Custard Creams are a distinct 165 g variant.
These options include a custard cream and two different sandwich biscuits for revision breaks. If the custard-cream flavour matters to you, compare that option separately from the alternatives.

If you want custard creams rather than a different sandwich biscuit, this is a 125 g gluten-free option. Compare the current pack’s sugars per 100 g and per biscuit before choosing a portion.
No image available
If you are open to a sandwich biscuit instead of custard creams, this is a 97 g Oreo Zero Sugar variant. Check its nutrition panel and ingredients rather than using the product name as a per-biscuit sugar figure.
No image available
This 210 g cookies-and-cream biscuit is an alternative when you do not need the custard-cream variant. Read its nutrition panel for total sugars per 100 g and check the ingredients before comparing it with another biscuit.
No. It identifies the lowest listed total sugars per 100 g among the packs being compared, not a substantiated nutrition claim for that product. Compare current labels on the same basis and treat a ‘reduced sugars’ claim as a separate question.
Read the delivered pack’s ingredients, allergen declaration and precautionary statements before sharing it. The checked Tesco and Asda packs identify wheat and milk ingredients, but online information may change and cannot replace the current pack label.
Check the exact pack and its availability when you order. The checked Sainsbury's and Crawford's listings mark their packs out of stock, while the checked Joybuy listing says McVitie's Tasties Custard Creams are no longer available.
No: promotion rules do not by themselves determine whether a school may provide a particular biscuit. For England, the Department for Education says current school food standards are a legal requirement for state-funded schools. For a school purchase, check the applicable nation’s school-food framework and how the food will be provided rather than assuming one UK-wide answer for every pack.
Follow the instructions on the particular pack. The checked Tesco, Sainsbury's and Crawford's listings advise a cool, dry place and an airtight container after opening.
