A slow cooker is one of those kitchen tools that earns its place by being genuinely useful rather than impressive. You load it in the morning, go about your day, and come home to something that smells good and tastes better than it would have if you’d rushed it. For soups, stews, casseroles, pulled meat, and cheap cuts of everything, it’s hard to beat. This is part of our complete kitchen tools and equipment guide. We also have a collection of budget winter slow cooker recipes for the colder months.

How we chose these slow cookers
We compared capacity against household size, how evenly each holds a low setting over eight hours, whether the pot is dishwasher-safe and hob-safe for browning, and running cost at current UK electricity rates. These are researched picks, not first-hand reviews, and we don’t accept payment for placement. I cook with a slow cooker at home, and my apple-cider pork shoulder has been in rotation for three or four autumns. Read our full methodology →

Our Top Picks in Detail
Best Overall
Salter Digital 6.5L
The Salter Digital 6.5L is the straightforward choice for most households, and especially for a family or anyone batch-cooking for the week. The 6.5L capacity handles whole joints, large pots of soup, or enough stew to fill the freezer. A digital display gives you three heat settings, a built-in cooking timer and an automatic keep-warm function, so you can set it going in the morning and leave it to do its work. The pot lifts out for easy cleaning.

Best Budget Slow Cooker
Tower Cavaletto 3.5L
This is the slow cooker to buy if you’re not sure yet whether you’ll use it regularly or want to start simply. It has three settings on a dial (low, high, keep warm), a removable pot that goes in the dishwasher, cool-touch handles, a toughened glass lid, and a 3.5L capacity that’s right for two to four people. Tower back it with a three-year guarantee once you register it. There is no programmable timer, so if you want it to switch itself off, a plug-in timer socket does that job for about £8.
Tower Cavaletto 3.5 Litre Slow Cooker with 3 Heat Settings, Removable Pot and Cool Touch Handles, Grey and Rose Gold, T16042GRY
Best Compact
Morphy Richards Sear & Stew 3.5L
The Sear & Stew’s distinguishing feature is its hob-safe insert — you can brown meat directly in the pot on the hob before transferring it to the slow cooker base. This saves washing up a separate pan and gives you better flavour from a proper sear. It’s compact at 3.5L, right for one or two people, and buyers consistently describe the build as solid.

Best Multi-Cooker
Instant Pot 7-in-1
The Instant Pot pressure cooks, sautés, steams, makes rice, and also slow cooks. If you’re someone who’d use all those functions, it earns its worktop space. The slow cooker function works well, though it runs slightly hotter than a traditional slow cooker. If you’d genuinely use it as a pressure cooker too, it’s excellent value.

What to Look For
Capacity is the most common mistake — buy one that’s too small and the liquid reduces too fast. As a rough guide: 3–3.5L for one to two people, 4.5–5.5L for three to four, 6L+ for families or batch cooking. A built-in timer that switches to keep-warm automatically is genuinely useful. Traditional slow cookers are very energy-efficient — a 200–320W model running for 8 hours costs around 40–65p. Wondering about running costs? Our piece on slow cooker electricity costs breaks it down.
If you’re new to slow cooking, our collection of slow cooker meals for a calm week is a good place to start — twelve comforting recipes with timings and a freezer plan. And if you’re curious about running costs, we worked out how much electricity a slow cooker actually uses. You’ll find all our kitchen picks in the Buying Guides.

A slow cooker as a gift
A slow cooker is a kind present for someone who would like a hot dinner waiting at the end of the day: it is loaded in the morning and left to get on with it. Match the size to the household. For a family or for batch cooking, the Salter Digital 6.5L handles whole joints and big pots of stew, with a cooking timer and an automatic keep-warm. For one or two people, the Morphy Richards Sear & Stew 3.5L has a pot that goes on the hob first, so meat can be browned without a second pan. The Tower Cavaletto 3.5L is the budget pick, with a three-year guarantee once it is registered, and for someone who would also use a pressure cooker, the Instant Pot 7-in-1 does both.
The Tower has no timer, so for someone out at work all day, a plug-in timer socket (about £8) makes a sensible extra.
Common Questions
What size slow cooker do I need?
For one or two people, a 3.5-litre slow cooker is usually enough. For a family of four, go for 5–6 litres. If you like batch cooking or making big stews, a 6-litre or larger model gives you room to cook ahead and freeze portions.
Can you leave a slow cooker on all day while at work?
Yes — that is exactly what they are designed for. Set it on low before you leave and dinner is ready when you get home. Just make sure the lid is on properly and the cooker is on a stable, heat-resistant surface away from anything flammable.
Is a slow cooker cheaper to run than an oven?
Significantly. A slow cooker uses roughly 150–300 watts over 8 hours on low, which costs around 30–65p depending on your tariff. An oven running for 2 hours uses considerably more energy. It is one of the most cost-effective ways to cook.
Do you need to brown meat before slow cooking?
You do not have to, but it makes a real difference to flavour. Browning creates a caramelised crust that adds depth to stews and casseroles. If you are short on time, you can skip it — the meal will still be perfectly edible, just a little less rich in flavour.
Is a slow cooker a good gift?
Yes, especially for someone who wants dinner ready when they get home. The Salter Digital 6.5L suits a family or batch cooking, the Morphy Richards Sear & Stew 3.5L suits one or two people and browns meat in the same pot, and the Tower Cavaletto 3.5L is the budget choice.
Our top pick
Salter Digital 6.5L
The best all-round slow cooker for most UK households. The 6.5L pot handles whole joints, big pots of soup or enough stew to fill the freezer; a digital display gives three heat settings, a cooking timer and an automatic keep-warm, so you can set it going in the morning, and the pot lifts out for easy cleaning.

Swan Retro SF17021 — bought largely on looks, and the styling is genuinely lovely, but the temperature regulation runs hot on the low setting, which catches out anyone slow-cooking for 8+ hours.
