Sweets made without added sugar have come a long way. If you are following a keto diet, counting calories, or simply cutting back on sugar, the sugar free sweets on the UK market in 2026 are worth a second look.

Gone are the days of chalky, chemical-tasting alternatives. Modern sugar-free confectionery has caught up with traditional sweets in every way that matters: flavour, texture, and sheer variety. At the centre of that shift in the UK sits Diablo Sugar Free, a brand built around one idea: the taste, without the added sugar.

This guide gives you 15 fully reviewed picks, an honest comparison table, a sweetener explainer, and everything else you need to shop with confidence. Let's get into it.

What Are Sugar-Free Sweets?

Sugar-free sweets are confectionery products made without added sucrose (table sugar). Instead, manufacturers use authorised sweeteners, such as polyols (sugar alcohols), steviol glycosides, isomalt, or erythritol, to replicate the sweetness and mouthfeel of traditional sweets.

Two common 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.

The UK's sugar-free confectionery market is growing rapidly. According to Grand View Research, the global sugar-free confectionery market was valued at over USD 2.45 billion in 2024 and is projected to grow at 4.2% CAGR through 2030, with the UK ranked among the top five global markets driving that expansion.

Why Choose Sugar-Free Sweets in 2026?

Consumer habits are shifting faster than ever. Mintel research confirms that nearly two-thirds of British consumers are actively taking steps to moderate their sugar intake. Here are the most important reasons UK shoppers are making the switch:

For People Managing Their Sugar Intake

Diabetes UK puts the number of people diagnosed with diabetes in the UK at around 4.3 million, and many more people are reducing their sugar consumption for their own reasons. Traditional sweets are built on sucrose. Polyols are used instead, and they are absorbed slowly, which is the point of using them. On maltitol specifically, the GB nutrition and health claims register permits one claim: consumption of foods containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods.

If you're managing a medical condition including diabetes and considering changes to your diet, always consult your GP, diabetes nurse, 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. 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, though rarely by as much as people expect. Anyone counting carbohydrates on a ketogenic or low carb plan works from the panel: total carbohydrate, of which sugars, of which polyols, all three printed on the pack.

For Families & Children

Plenty of households are simply trying to cut back on refined sugar across the family shop. Diablo's Gummy Bears and Cola Bottles are two of the range's most popular lines, and the Gummy Bears use natural colourings only. 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 works from numbers rather than claims. 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.

Understanding Sweeteners: What Makes These Sweets Sugar-Free?

One of the most common questions about sugar-free sweets concerns the sweeteners used. Here is what each one in the Diablo range actually is, and what its label has to declare:

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, which is the point of using them. 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 glycemic 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 glycemic 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) contain no added sucrose or fructose, though naturally occurring sugars from ingredients may be present, so always check the nutrition panel.

Different sweeteners carry different published glycemic index figures, and the ingredient list tells you which one a product uses. On maltitol, the GB nutrition and health claims register permits one claim: consumption of foods containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods. That is the only wording worth relying on.

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

Sugar Free Sweets and Children: What Parents Ask

Plenty of parents are cutting back on the sugar in the family shop. Nothing here rates a product for a child, and that judgement stays with the parent. These are the facts on the pack that the question usually turns on:

• Portion sizes: polyols are absorbed slowly, which is the point, and 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 use natural colourings only. 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.
• Made with sweeteners instead of sugar: these products contain no added sugar, and the sweetness comes from polyols, which are not sugars. The sugars and polyols lines on the panel give the figures.
• Confectionery is confectionery: every published dietary framework treats sweets of any kind as an occasional food rather than a staple, whichever sweetener they use.
• 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.
