Best Sugar-Free Sweets UK: Top 15 Picks for 2026

Two of ours to start with:

Sugar Free Gummy Drops 75 g

0.1 g sugars per 100 g, sweetened with maltitol and set with gelatine

Sugar Free Fruit Flavoured Toffees 75 g

0.2 g sugars per 100 g, sweetened with maltitol and isomalt

The picks run from gummies and cream sweets to chocolate, cookies, wafers, a muesli bar and a spread. Each card gives the sugars per 100 g from our product records for that exact pack.

What Are Sugar-Free Sweets?

Sugar-free sweets are confectionery with no more than 0.5g of sugars per 100g, the condition UK law sets for the claim. In place of sucrose (table sugar), manufacturers use authorised sweeteners such as polyols (sugar alcohols: isomalt, maltitol, sorbitol and erythritol among them) and steviol glycosides to replicate the sweetness and body of traditional sweets.

Three label claims are worth separating:

SF and NAS are two distinct claims with two distinct legal definitions. The nutrition panel carries the actual figures for the product in your hand.

How Do Other UK Sugar Free Sweets Compare?

Diablo is not the only sugar free line on UK shelves, and the makers of two other lines publish which sweeteners they use. Storck's UK website states that Werther's Original Sugar Free is made with isomalt and acesulfame K. A.L. Simpkin's technical information states that its sugar free boilings are made with isomalt and sucralose.

Each maker's own published statement, checked October 2026. Formulations change, so the pack in your hand is the final word.

Why Choose Sugar-Free Sweets in 2026?

Shoppers start at different lines of the label:

For People Managing Their Sugar Intake

Traditional sweets are built on sucrose. Ours use polyols instead, which are absorbed slowly. On maltitol specifically, the GB nutrition and health claims register permits this claim: "Consumption of foods/drinks containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods/drinks". It applies where the sugars are reduced by at least 30 percent against comparable foods.

If you're managing a medical condition including diabetes and considering changes to your diet, always consult your GP or registered dietitian for personalised advice. They can help you understand how different sweeteners and food choices fit into your individual dietary plan.

For Calorie and Carbohydrate Counting

Sugar carries 4 kcal per gram. Most polyols are labelled at 2.4 kcal per gram under GB and EU rules, so the energy figure on a polyol sweetened product is usually lower than a conventional equivalent. Anyone counting carbohydrates on a ketogenic or low carb plan works from the panel: total carbohydrate, of which sugars, of which polyols, all three where the pack declares them.

For Families & Children

Diablo's Gummy Bears take their colour from apple, carrot, pumpkin and blackcurrant concentrates, and the Cola Bottles from carrot, apple and hibiscus. What belongs in a particular child's diet is a parent's call, and the pack carries the ingredient list and the nutrition panel to make it on.

For Fitness Enthusiasts

Anyone tracking macros needs the panel figures. Sweets made without added sugar still carry calories and carbohydrate, and both are printed on the panel, which is what makes them straightforward to log. Diablo's Hazelnut Muesli Bar is oat based and comes in a single 30g portion, which makes the arithmetic simple.

How We Selected the Top 15

Our selection criteria for the best sugar-free sweets available to UK buyers in 2026 are built around what actually matters to real consumers:

• Taste and texture: does it genuinely replicate the sugar-filled original in flavour and mouthfeel?
• Sweetener: which sweetener does it use, and is it declared clearly on the pack?
• Nutritional profile: calories, carbohydrate and sugars per 100g, verified against COA data
• Pack facts: halal, kosher and vegetarian status taken from our certificate records, never guessed from the ingredient list
• UK availability: can UK shoppers easily buy it online or in store?
• Range diversity: gummies, boiled sweets, chocolate, biscuits, bars and spreads are all represented

Every product in this list is available directly from Diablo Sugar Free at diablosugarfree.com, where you'll also find multi-pack options and a wholesale page for trade buyers.

Understanding Sweeteners: What Makes These Sweets Sugar-Free?

One of the most common questions about sugar-free sweets concerns the sweeteners used. Here are the main sweeteners in sugar free confectionery and what each label has to declare. Diablo uses isomalt, maltitol, sorbitol, steviol glycosides and acesulfame K; xylitol and erythritol are in the table for comparison.

Polyols (Sugar Alcohols): The Foundation of Sugar Free Confectionery

All Diablo SF and NAS products are sweetened with polyols (sugar alcohols). Polyols occur naturally in some fruits and vegetables, and they are absorbed slowly. GB and EU labelling rules assign them 2.4 kcal per gram against 4 kcal for sugar. The specific polyol varies by product, so check the "of which polyols" figure on the panel. Every polyol used is authorised under UK and EU food law.

Isomalt: The Boiled Sweet Specialist

Isomalt is a polyol made from beet sugar, authorised as E953 and labelled at 2.4 kcal per gram against 4 kcal for sugar. It is extremely stable at high temperatures, which is what makes it the standard choice for hard boiled sweets. Clean, consistent sweetness with minimal aftertaste and a published glycaemic index of around 2.

Stevia: The Plant Derived Option

Stevia sweeteners are steviol glycosides extracted from the leaves of the Stevia rebaudiana plant, authorised as E960 and carrying a glycaemic index of zero. They are intensely sweet, so inclusion rates are tiny: 0.02% in the Diablo bars that use them, usually blended with a polyol to carry the bulk and the flavour balance.

Sources: GB and EU authorised sweetener lists, GB nutrition and health claims register, Mayo Clinic. GI values are published reference figures and vary by individual. Always check individual product labels for the specific sweetener used.

Reading a Sugar Free Label: What Each Line Means

Products labelled Sugar Free (SF) contain a maximum of 0.5g sugars per 100g and are sweetened with polyols or other sweeteners instead of sucrose. Products labelled No Added Sugar (NAS) have no sugars added, though naturally occurring sugars from ingredients may be present, so always check the nutrition panel.

Different sweeteners carry different published glycaemic index figures, and the ingredient list tells you which one a product uses. On maltitol, the GB nutrition and health claims register permits this claim: "Consumption of foods/drinks containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods/drinks". It applies where the sugars are reduced by at least 30 percent against comparable foods.

If you are managing diabetes or any other medical condition, speak with your healthcare team about your diet. They can provide guidance on appropriate portion sizes and how different sweeteners fit into your individual dietary plan.

Five Checks Before You Buy

1. The "of which sugars" line: 0.5g per 100g or less on anything sold as sugar free.
2. The first sweetener named: ingredients are listed in descending order by weight, so the first sweetener is the main one. Isomalt leads in Diablo's cream sweets; maltitol leads in the gummies and the chocolate.
3. Where the sugars come from: on a No Added Sugar pack, the ingredient list shows the source of the sugars on the panel, usually milk powder or fruit.
4. The polyols line: where a pack declares polyols, they sit on their own line under carbohydrate, apart from the sugars.
5. Gelatine and allergens: gummies are usually set with gelatine. Diablo's are; the cream sweets are not. The allergen box differs by pack, so read it for each one.

Sugar Free Sweets and Children: What Parents Ask

We do not rate any product for a child. That call is the parent's. These are the facts on the pack that the question usually turns on:

• Portion sizes: packs above 10 percent polyols carry the note that excessive consumption may produce laxative effects. A small portion to start with lets the gut adjust, and portions scale with body weight.
• Colours: Diablo's Gummy Bears take their colour from fruit and vegetable concentrates. In GB and the EU, six specific colours carry the mandatory statement that they may have an adverse effect on activity and attention in children, so the ingredient list is where to check. The Strawberry & Cream Sweets use one of them, E129, and carry that statement on the pack.
• Made with sweeteners instead of sugar: these products contain no added sugar, and the sweetness comes mainly from polyols, which are not sugars. The sugars and polyols lines on the panel give the figures.
• Ask the people who know your child: if a paediatrician, dietitian or dentist is already advising on their diet, that advice takes precedence over anything on this page.

Which Sugar Free Sweets Suit Vegetarian, Halal or Kosher Diets?

Dietary status comes from our certificate records for each pack, not from reading the ingredient list. Here is where each of the 15 picks stands:

"No" means the pack holds no certificate for that standard in our records, not that it fails one.

For vegetarians, the gelatine column does most of the work. Our records class the cream sweets, the three chocolate bars, the cookies, the wafers, the muesli bar and the spread as vegetarian, although none of those packs prints it. Our records also class the muesli bar as vegan; its pack does not print that either. The gummies and the toffees are set with gelatine.
