The UK's main high-protein meal prep delivery services are Frive, Prep Kitchen, Simmer Eats, Fuel Hub and HelloFresh. The fairest way to compare their protein is per 100g of food, because a bigger portion always flatters a per-meal figure. Gram for gram, Frive and Fuel Hub are effectively level, at around 12 to 13g of protein per 100g, and Fuel Hub's extra protein per meal comes from bigger portions. Once delivery is counted, six fresh meals cost £47.40 to £54.95, and Frive is the lowest.
High-protein eating has moved far beyond the gym. Searches for high-protein foods have more than doubled in recent years as people look for meals that boost energy and keep them fuller for longer, and social media has turned simple ingredients like cottage cheese and Greek yoghurt into viral favourites. Below, we compare five of the UK's top high-protein meal prep delivery services to help you choose the best fit for your lifestyle.
TL;DR: the main contenders
If you only read one section, read this. These are the five services worth shortlisting, and what each is known for:
Frive: flavour-first fresh meals made from whole foods and 100% UPF free, with a median of 44g of protein, from £7.90 a meal with free delivery over £40.
Prep Kitchen: structured fat loss and muscle gain plans with around 40g of protein per meal, from £6.95 a meal plus £5.99 delivery.

HelloFresh: recipe kits you cook yourself, with recipes tagged High Protein.
All five are compared side by side below. One notable change this year: Calo, previously a popular pick, ceased UK operations in May 2026 and no longer features.
High-protein meal prep providers compared at a glance
How we compared these services
We assessed each service against the things that actually matter for high-protein eating: protein per 100g as well as per meal, what goes into the food (including what each brand says about ultra-processed food), freshness and format, macro visibility, dietary coverage, delivery flexibility, and what six meals really cost once delivery is added. Facts were taken from each provider's own website and published nutrition, alongside Trustpilot scores. We removed one former contender, Calo, after it closed its UK operations in May 2026. Prices and menus change, so always confirm current details with the provider before ordering.
The 5 best high-protein meal prep delivery services in the UK
The high-protein meal prep market has grown fast, with more providers offering ready-made or cook-at-home options that promise better nutrition and convenience. These are the five services that stand out in 2026, compared on the details that matter.
1. Frive
Frive makes fresh, high-protein meals from whole ingredients, and we're 100% UPF free. We put flavour first: every dish is chef-prepared, nutritionist-approved and delivered chilled for better flavour, texture and overall freshness.

3. Simmer Eats
Simmer Eats offers chef-prepared meals in three portion sizes, lean, standard and large, with around 40g of protein in a standard portion, so you can match calories and protein to your training.

4. Fuel Hub
Fuel Hub is a chilled meal prep service with a sports nutrition focus and 35 meals on a menu that changes monthly. Its meals are big, with a median of 56g of protein in a 435g meal, but gram for gram they're level with ours at around 12 to 13g per 100g, so the extra protein comes from portion size. We're 100% UPF free; we couldn't find a UPF-free claim on Fuel Hub's website, so if that matters to you, it's worth asking Fuel Hub directly about what goes into its meals.
Best for: bigger appetites who want larger portions.

5. HelloFresh
We appreciate HelloFresh isn't a meal prep service, but we've included it for anyone interested in cooking their own high-protein meals. Its recipe kits come with fresh, pre-portioned ingredients and a large weekly menu with recipes tagged High Protein, though cooking time and extra cleanup won't suit everyone.
Best for: people who enjoy cooking and want a large choice of protein-focused recipes.
Specs (at a glance):
Format: recipe kits to cook at home with fresh, pre-portioned ingredients.
Protein: HelloFresh's “High Protein” tag means at least 20% of a recipe's calories come from protein.

Also considered
These services didn't make our top five for high-protein eating specifically, but each is worth knowing about, and one of them may fit your budget or style better:
Prepped Pots: MuscleFood's budget range of ready-made pots, from £2.49 a meal on its own website. It's a simpler, budget format than the fresh services above. See our full Frive vs Prepped Pots comparison.
All Week: fresh, never-frozen meals from chefs with fine-dining backgrounds, ready in four minutes and delivered on Wednesdays and Saturdays. It doesn't publish protein figures on its homepage, so check each dish.
Calo: formerly one of the most personalised options in the UK (and previously known as Fresh Fitness Food), Calo ceased UK operations in May 2026, so it no longer appears in this comparison.

Why protein per 100g is the fairer comparison
A meal needs at least 30g of protein to qualify as genuinely high-protein, and 40g or more if you train hard or want maximum satiety. That is roughly the amount research on muscle building suggests the body can use effectively in one sitting for muscle repair and growth. Quality matters as much as quantity: meals built on chicken, fish, eggs, dairy and pulses beat those that lean on processed fillers to inflate the numbers. Every ready meal service in this comparison clears the 30g bar on most of its meat and fish dishes; they differ on how protein-rich the food itself is.
A bigger meal will always carry more protein, so a per-meal figure partly measures portion size. Protein per 100g shows how protein-rich the food itself is, and it's the same measure you'll find on the back of any UK food label. We worked it out for every service that publishes enough to do so.
Gram for gram, Frive and Fuel Hub are effectively level, and both are ahead of Simmer Eats. Fuel Hub's meals carry more protein per meal because they're bigger: its median meal weighs 435g against our 388g. So its extra protein comes from a larger portion, not a more protein-rich meal.
If you want more protein for fewer calories, look at our Lean versions, which have fewer calories and carbs: across the 17 on this week's menu, the median is 50.5g of protein at 478 calories.
How we worked it out: protein per 100g is each meal's published protein divided by its weight, from each brand's own website (for Frive, from our recipe data). We've given a range because the answer moves slightly depending on how you average across a menu. Simmer Eats figures come from the per-100g values on its product pages.
DIY high-protein meal prep vs delivery: which is better?
Batch cooking your own meals is cheaper; delivery wins on time, consistency and macro certainty. Cooking a week of high-protein meals yourself can cost £3 to £4 per portion, but it demands a couple of hours of shopping, cooking and washing up every week, and macro accuracy depends on you weighing everything. A delivery service costs more per meal but guarantees the protein number on the label and hands you back your Sunday. Many people land on a hybrid: a part-week plan from a service, topped up with simple home-cooked meals. If you want to try the DIY route first, our 7 day meal prep plan for muscle gain is a good place to start.
What to look for in a high-protein meal prep service
High-protein meal prep suits anyone who wants to hit a daily protein target without cooking from scratch, whether you're training, managing your weight or just tired of deciding what to eat every day. When you compare services, these five things matter most:
Protein per meal and per 100g: aim for 30 to 40g a meal to support muscle repair, and check protein per 100g so portion size doesn't flatter the number.
What goes into the food: look for whole foods and a low reliance on ultra-processed ingredients, and check whether the brand says its meals are UPF free.
Format and freshness: meals arrive fresh, frozen or as recipe kits, so check how long they keep in the fridge and which delivery days suit your week.
Macro tracking and dietary needs: clear macros and MyFitnessPal support make body composition goals easier to hit; check the plan covers vegan, vegetarian, gluten-free or dairy-free needs.
What a week really costs: compare six meals delivered, not the price per meal, because delivery charges of £5.99 to £6.99 an order add up. Here's how much meal prep delivery really saves you.

FAQs
How much does high-protein meal prep delivery cost in the UK?
Fresh, ready-to-eat high-protein meals cost £6.95 to £8.00 a meal before delivery across the services here. Once delivery is counted, six meals cost £47.40 at Frive (free delivery over £40), £47.69 at Prep Kitchen, £51.93 at Simmer Eats and £54.95 at Fuel Hub. Recipe kits like HelloFresh cost less per serving, but you cook them yourself.
Which meal prep service has the most protein?
Per meal, Fuel Hub's larger meals carry the most, a median of 56g. Per 100g of food, which strips out portion size, Frive and Fuel Hub are effectively level, at around 12 to 13g, and both are ahead of Simmer Eats at around 10.5g. Frive's 43 mains have a median of 44g of protein per meal, with 39 carrying 30g or more.
How much protein should a meal prep meal contain?
A genuinely high-protein meal should contain at least 30g of protein, and 40g or more if you train regularly or want maximum fullness. That reflects the amount of protein the body can use effectively in one sitting for muscle repair, roughly 0.25 to 0.4g per kilogram of body weight per meal.
Is high-protein meal prep good for muscle gain?
Yes. Consistently hitting 30 to 40g of protein per meal across the day is one of the most reliable ways to support muscle growth alongside resistance training. Meal prep delivery removes the two biggest failure points, inconsistent cooking and inaccurate macros, by delivering verified protein counts on every label.
Which high-protein meal prep services are UPF free?
Frive is 100% UPF free. We found no UPF-free claim on the websites of Prep Kitchen, Simmer Eats or Fuel Hub; Simmer Eats says its meals are free from artificial preservatives, additives and processed fillers. If it matters to you, ask each brand directly.
Can you get halal high-protein meal prep in the UK?
Yes. Frive has a halal meal plan, though some of our meals and add-ons aren't halal, so check each dish. Simmer Eats includes halal options too. HelloFresh says it can't guarantee a halal meal plan, so recipe kits are a weaker choice if halal matters to you.
What happened to Calo in the UK?
Calo, the personalised meal plan service formerly known as Fresh Fitness Food, ceased its UK operations in May 2026. If you are a former Calo customer looking for a replacement, our guide to Calo alternatives in the UK compares the closest matches.
