Instant Pot Duo 7-in-1 Electric Pressure Cooker (5.7L) — Best overall

The Instant Pot Duo 7-in-1 has earned its spot as the best instant pot under £100 in the UK by doing the simple things well. The 5.7L stainless steel inner pot is large enough to cook 4-6 portions of stew, a whole 1.5kg chicken, or 500g of dried beans, while the 1000W heating element brings it up to pressure in roughly 12 minutes from cold. Seven functions cover pressure cooking, slow cooking (up to 4 hours), rice, sauté, steam, yoghurt, and warming, controlled by a single dial and three buttons rather than a touchscreen. In testing, beef stew reached fork-tender in 35 minutes against 2-3 hours on a hob, and dried chickpeas cooked in 25 minutes with no overnight soaking. The lid, steam rack, and condensation collector are all dishwasher-safe. The pressure release is louder than the Ninja Foodi, and there is no air-fry lid, but for under £90 the Duo 7-in-1 remains the UK benchmark for entry-level multi-cookers and a smarter buy than the Crock-Pot Express for most households.

Pros:

• Reaches pressure in 12 minutes
• Stainless steel inner pot browns well
• Dishwasher-safe lid and accessories

Cons:

• Manual pressure release is noisy
• No air-fry or sous vide mode

2. Instant Pot Duo Mini 7-in-1 Electric Pressure Cooker (3L) — Best for small kitchens

Price: 64.99 | Rating: 4.6/5 | Available at: amazon.co.uk

The 3L Duo Mini is the Instant Pot answer for UK flats, student digs, and couples who do not need 6 litres of capacity. The 700W element is gentler on a small kitchen’s electrics and brings 1.5L of water to pressure in around 8 minutes. The seven cooking functions are identical to the larger Duo, and the 14 preset buttons cover porridge, soup, and beans at the touch of a dial. It will not fit a whole chicken or a Sunday joint, but it cooks 2-3 portions of curry, chilli, or risotto in one go and weighs just 4.1kg, making it easy to lift off a 60cm worktop. The 3-year warranty applies UK-wide. For solo cooks in London or Manchester flats, this is the best instant pot under £100 for value and footprint.

Pros:

• Compact 3L size fits small kitchens
• Same 7 functions as the larger Duo
• Lightweight at 4.1kg

Cons:

• Cannot cook a whole chicken
• Smaller accessories included

3. Instant Pot Duo Plus 9-in-1 Electric Pressure Cooker (5.7L) — Best for extra functions

Price: 99.99 | Rating: 4.6/5 | Available at: amazon.co.uk

The Duo Plus is the most feature-packed Instant Pot you can buy under £100 in the UK. The 5.7L capacity matches the standard Duo, but you get 9 cooking modes including sous vide (precise temperature control from 25-90°C), yoghurt, sterilise, and a cake setting. The blue LCD screen replaces the basic dial, and 13 one-touch programs remove the guesswork from porridge, meat, and beans. It is the heaviest of the range at 6.2kg and the natural pressure release takes up to 15 minutes, so plan accordingly. At £99.99 it is only £10 more than the standard Duo, making it the smarter choice for keen home cooks who will use the sous vide and yoghurt settings regularly.

Pros:

• Sous vide and yoghurt modes included
• Large LCD with 13 one-touch programs
• Sterilise function for jars and bottles

Cons:

• Sits at the £100 ceiling
• Heavier than the standard Duo
• Natural pressure release is slow

4. Crock-Pot Express Crock Multi-Cooker (5.6L) — Best for slow-cooker fans

Price: 79.99 | Rating: 4.5/5 | Available at: amazon.co.uk

Crock-Pot’s Express is the natural upgrade for British households that already trust the brand for slow cookers. The 5.6L non-stick inner pot is shallower than the Instant Pot’s, which makes it better for browning large cuts of lamb shoulder and for layered lasagne-style bakes. The 1300W element is the most powerful in this guide, hitting pressure in under 10 minutes. Eight functions cover pressure, slow, sauté, steam, rice, and bake, though yoghurt and sous vide are missing. The 33cm footprint is wider than the Instant Pot, so measure your cupboard before buying. Backed by a 2-year UK warranty and stocked at Argos, it is a strong alternative to the Duo for those who bake and brown more than they pressure-cook.

Pros:

• 1300W is the most powerful under £100
• Trusted Crock-Pot slow-cooking brand
• Bake function for cakes and bread

Cons:

• Wide 33cm footprint
• No yoghurt or sous vide mode
• Non-stick coating rather than stainless

5. Russell Hobbs Good to Go Multi-Cooker (6L) — Best budget pick

Price: 54.99 | Rating: 4.3/5 | Available at: amazon.co.uk

At £54.99, the Russell Hobbs Good to Go is the cheapest genuine multi-cooker under £100 from a major UK high-street brand and is widely available at Argos, Currys, and Amazon UK. The 6L capacity out-sizes both the Instant Pot Duo Mini and the Duo 5.7L, making it good for batch cooking. Eight functions include pressure, slow, sauté, rice, and a 24-hour delay timer, though there is no yoghurt or air-fry function. The aluminium inner pot is non-stick rather than stainless steel, so it does not brown meat as well as the Instant Pot, and pressure control is less precise. The 2-year UK warranty is shorter than Instant Pot’s 3 years. For a first multi-cooker on a tight budget, it is hard to beat.

Pros:

• Cheapest on the list at £54.99
• Generous 6L capacity for the price
• Russell Hobbs UK customer support

Cons:

• Non-stick aluminium pot, not stainless
• Less precise pressure control
• Shorter 2-year warranty

How to choose

Choosing the best instant pot under £100 in the UK comes down to three main factors: capacity, functions, and warranty. First, match the capacity to your household — a 3L mini is ideal for 1-2 people, while a 5.7-6L unit is better for families of 4-6. Second, count the cooking functions. Genuine 7-in-1 units (pressure, slow, sauté, steam, rice, yoghurt, warm) cover most weeknight dinners, while 9-in-1 models add sous vide and sterilise. Third, check the warranty — Instant Pot offers 3 years, Crock-Pot 2 years, and Russell Hobbs 2 years, which matters for long-term value. Look for a stainless steel inner pot rather than non-stick, as it browns better and survives the dishwasher. Finally, buy from Amazon UK, Argos, or Currys to ensure a UK-plugged unit, a UK warranty, and easy returns — and avoid grey-market imports that will not be honoured by UK service centres.

Frequently asked questions

Is the Instant Pot Duo 7-in-1 worth buying in the UK?

Yes — the Instant Pot Duo 7-in-1 at £89.99 on Amazon UK is the best-selling multi-cooker in Britain, with over 8,000 reviews averaging 4.7 stars and a 3-year UK manufacturer warranty for peace of mind.

What is the difference between the Instant Pot Duo and Duo Mini?

The full-size Duo 7-in-1 is a 5.7L unit with a 1000W element suitable for families of 4-6, while the Duo Mini is a compact 3L model with a 700W element designed for 1-2 people, students, and small kitchens.

Can I buy an Instant Pot under £100 in the UK with an air fryer?

Not really — the Instant Pot Duo Crisp with Air Fryer Lid typically costs £130-150 in the UK, putting it above the £100 budget. For a cheaper air-fryer alternative, consider the Ninja 2-in-1 multi-cooker from £119.

How long does an Instant Pot last?

With proper care, Instant Pot multi-cookers last 5-8 years. The silicone sealing ring should be replaced every 12-18 months, and the stainless steel inner pot will last longer if hand-washed. UK warranty cover is 3 years on the Duo range.

Is the Instant Pot cheaper than the Ninja Foodi in the UK?

Yes — the Instant Pot Duo 7-in-1 starts at £89.99 in the UK, while comparable Ninja Foodi 7-in-1 models begin at around £129.99, putting Ninja firmly in the over-£100 bracket for equivalent capacity.

Can I use an Instant Pot as a slow cooker?

Yes — all Instant Pot Duo models include a slow-cook function with Low and High settings up to 4 hours, making them a direct replacement for a standalone Crock-Pot for stews, curries, and joints.

What size Instant Pot do I need for a family of 4?

For a family of 4, choose a 5.7L (6-quart) Instant Pot such as the Duo 7-in-1 — it fits a whole chicken, 1kg of stewing beef, or 8 portions of rice. The 3L Mini only serves 1-2 people and is too small for family meals.

Are there good alternatives to Instant Pot under £100 in the UK?

Yes — the Crock-Pot Express (£79.99) and Russell Hobbs Good to Go (£54.99) are solid alternatives stocked at Argos, Currys, and Amazon UK, though they offer fewer cooking presets and shorter warranties than the Instant Pot Duo.

We excluded grey-market imports, refurbished units, and products without UK plug warranties. Prices were verified on the day of publication and may fluctuate. The Instant Pot Duo 7-in-1 emerged as the best instant pot under £100 in the UK, scoring highest on function count, stainless steel build, 3-year warranty, and verified UK buyer satisfaction above 4.6 stars.
