Slow and pressure cookers

Slow and pressure cookers usage and safety

Slow cookers are a low-maintenance, easy way to create delicious meals while pressure cookers use less energy and save time when cooking.

A slow cooker uses low heat over a long period to tenderize food, perfect for stews and pot roasts, while a pressure cooker uses high heat and high pressure to reduce cooking times significantly.

Some modern multi-cookers or instant pots combine both functions, allowing you to switch between slow cooking and pressure cooking in a single device.

Key points

  • Slow and pressure cookers must be fitted with a UK 3-pin plug and fuse. 

  • Look for appliances with safety features to minimise the risk of accidents. 

  • Do regular checks of the plug socket and cable for burn and scorch marks. 

  • Read the manufacturer's instructions carefully and always follow them. 

Buying a slow or pressure cooker

  • Whichever you choose, buy from a reputable retailer rather than a third-party seller online, as the appliance may not have passed all the necessary safety checks. Make sure it is fitted with a standard UK 3-pin plug and fuse.
  • You will find lots of online reviews of slow and pressure cookers but don’t rely solely on these as they can be faked by unscrupulous sellers.
  • Look for safety features on the appliance such as safety valves for releasing pressure, locking lids, and anti-blocking devices. Slow cookers often have automatic shut-offs and cool-touch exteriors.
  • Register your appliance so you can be contacted easily if there is a safety recall of your product. It’s also much easier to return a faulty item or order a repair if it’s registered. 

Using a slow or pressure cooker safely

  • Always set the cooker on a heat-proof surface and keep it at least six inches away from the wall.
  • Keep the power cable away from the edges of the cooker
  • Don’t overfill, check the manufacturer’s instructions and follow them. Typically, a pressure cooker should be maximum two-thirds full and a slow cooker maximum three-quarters full. But for expanding foods such as rice or grains it may be less. In a pressure cooker, use enough liquid – normally around 250ml – and only a tiny amount of oil as any more could melt the gasket.
  • With a slow cooker, if you want to leave the house while it is running, set it on low. Only use the high heat option when you are in the house.
  • To clean your cooker safely, follow the manufacturer's instructions. Unplug it before cleaning, dismantling, or when not in use.
  • Check which parts are dishwasher-safe and which should be washed by hand. Ensure all components are completely dry before reassembling and using the cooker again.
  • If you notice any unusual smells or noises such as sparking or buzzing, unplug the cooker immediately and contact the retailer or manufacturer.

ALWAYS

  • Do plenty of research first before buying. 
  • Buy a known and trusted brand from a reputable retailer.
  • Register your appliance with the manufacturer.
  • Clean the appliance according to the manufacturer’s instructions.

      

AVOID

  • Buying from third-party sellers online.
  • Using a high heat option while you are out of the house.
  • Using the appliance if you notice unusual smells or noises.
  • Overfilling with either food or water. 

Stay safe with electrical products

Check plugs and sockets

Don't ignore burn marks, ‘arcing’ (buzzing or crackling) sounds, fuses blowing, circuit-breakers tripping, or if it feels hot to touch.

Unplug and contact the retailer, manufacturer, or a qualified repair technician. 

Protect with an RCD

An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks if a product is faulty.

If you don’t have RCD protection, use an RCD plug on the socket where the product is plugged in.

Fit smoke and heat alarms

Ensure there is at least one smoke or heat alarm per floor in your property. Fit enough alarms to cover all areas where a fire could start.

Test alarms at least once a month. Replace them every ten years or when the replace by date is reached.

Selected FAQs

If you’re unsure about an appliance or product, you’re not alone. These FAQs bring together expert advice and answers to the questions people ask us most, so you can feel more confident at home.

It is recommended that periodic inspection and testing is carried out at the following times:

  • for tenanted properties, every 5 years or at each change of occupancy, whichever is sooner
  • at least every 10 years for an owner-occupied home
  • at least every 5 years for a business

The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.

Periodic inspection and testing of the electrics should be carried out more frequently on the places and premises listed here:

  • 3 years for a caravan
  • 1 year for a swimming pool

Periodic inspection and testing should be carried out only by electrically competent persons, such as registered electricians.

First, you need to find out whether the electrician you used is actually registered. To do this, contact the operator of the scheme they have claimed to be part of, and they will tell you whether this is the case. If they are registered, the scheme operator can guide you through their complaints procedure.

If you find out the electrician misled you and is not registered, you should report this to your local Trading Standards Department as they are breaking the law. We would also recommend that you get an Electrical Installation Condition Report (EICR) carried out on your home; this will assess any work that has been undertaken and will act as sufficient documentation to certify that work. This needs to be carried out by a registered electrician and unfortunately will be an added cost for you.

Additional info

Energy efficiency is about total energy use over time. A slow cooker typically uses 150-300 watts of power but it’s usually on for many hours, whereas a modern electric pressure cooker typically consumes 700-1,000 watts but only runs for a short time.

But compared to ovens, which can consume 2,000-3,000 watts, both are far more energy efficient.

Has your electrical product been recalled?

Electrical products are recalled more regularly than you might think, but the response rate to a recall is often worryingly low. This means there are potentially millions of recalled electrical items still in UK homes.
