Best Electric Knife Accessories in the UK: Where to Buy Replacement Blades, Parts and Upgrades

Why electric knife accessories matter

Think of an electric knife as a small kitchen power tool — and like any power tool, it performs best when you treat it right. Accessories such as replacement blades, cleaning brushes, storage sheaths, and spare batteries keep your knife slicing cleanly and safely. Whether you carve a Sunday roast, trim a bread loaf, or prepare delicate fish, the right accessory can make a noticeable difference in speed and finish. Ready to stop fighting with a dull blade? Let’s walk through where to buy the best electric knife accessories in the UK and what to look for.

Top UK retailers that stock electric knife accessories

You don’t need to hunt around every high street and online marketplace to find quality parts. Several well-known UK retailers carry a reliable range of electric knife accessories — from branded blades to useful add-ons. Below I break down the high-street and online options so you can shop confidently and compare price, availability, and shipping.

John Lewis

John Lewis is a go-to for shoppers who want quality and good customer policies. They stock accessories for popular electric knife brands and often provide detailed product descriptions so you can verify blade length in inches and compatibility. Their selection tends to include premium replacement blades and branded add-ons, making John Lewis a solid choice if you want to stick to original equipment manufacturer (OEM) parts.

Argos

Argos is practical, convenient, and often budget-friendly. You’ll find both branded and compatible replacement blades, storage cases, and cleaning tools at different price points. Argos’s widespread catalogue and fast collection options are handy if you need a replacement blade quickly. They usually list blade sizes and compatibility, so double-check the measurements in inches before you buy.

Currys

Currys is known for a broad range of household electricals, and electric knives are no exception. Here you’ll spot accessories that suit mainstream brands and a fair selection of spare batteries and chargers. Currys is a smart stop if you’re pairing a new accessory with other kitchen tech purchases and want to take advantage of seasonal deals.

Lakeland

Lakeland is beloved by serious cooks and gadget lovers. Their curated range often includes specialist blades, carving sets, and well-thought-out storage solutions — perfect if you care about presentation and longevity. If you prefer accessories that are designed for home cooks rather than industrial use, Lakeland is a warm, practical choice.

Amazon UK

Amazon UK is hard to beat for sheer variety. You’ll find OEM parts, third-party compatible blades, cleaning kits, and even niche accessories like jigs for consistent slicing. The trick here is to read reviews and check blade measurements in inches and compatibility notes. Prime delivery can also save the day if you’re mid-prep and need a part fast.

Robert Dyas

Robert Dyas offers a good mix of functional accessories and value buys. Their stores and website stock replacement blades and handy cleaning tools that suit many household electric knife models.

Wayfair UK

Wayfair is more than furniture — it’s a place for home gadgets and accessories too. They sometimes carry less common accessories and alternative-brand blades that you might not find on other high streets. If you’re after a specific blade length in inches or a unique sheath, Wayfair’s broad marketplace model can help you find it.

Homebase

Homebase often stocks practical accessories for household tools, including replacement blades and cleaning kits for electric knives. While their selection can vary by location, checking online first can save time. Homebase is a good option if you’re combining kitchen repair or upgrade tasks with other home-improvement shopping.

Types of electric knife accessories you should know about

Accessories come in different shapes and purposes: blades, maintenance tools, storage, and power-related parts. Choosing the right accessory depends on your knife model and how you use it. Let me break down the essentials so you know which items are worth investing in.

Replacement blades

Replacement blades are the most obvious accessory. They come in straight or serrated profiles and in varying lengths — usually listed in inches. Serrated blades are ideal for bread and delicate crusts, while straight blades work well for meats and roasts. When shopping, always match the blade’s mounting system and length in inches to your knife’s specifications to avoid fit problems.

Cleaning brushes and maintenance kits

Cleaning brushes and maintenance kits help keep the mechanism free of crumbs and grease. Small, stiff-bristle brushes reach into the teeth and grooves where food particles hide. Some kits also include lubricant for moving parts — a tiny amount can extend the life of the driver mechanism and make slicing smoother. Think of these kits as the toothbrush for your knife: quick, cheap upkeep that prevents major problems down the line.

Storage sheaths and cases

A good sheath or case protects blades and keeps them from dulling in a drawer. Look for cases that cover blade tips fully and have a secure latch. If you travel with your electric knife or use it seasonally, a padded case will protect both the blade and your hands. Consider a wall-mount storage option if bench space is tight — it keeps the tool visible and saves drawer clutter.

Spare batteries and chargers

If your electric knife is cordless, having a spare battery or a fast charger is worth it. Some manufacturers offer OEM batteries measured by voltage and runtime; others use standardised battery types. If you’re comparing specs, convert runtimes into hours and power into battery capacity, but keep in mind the practical difference: a spare battery gives you uninterrupted slicing during long meals or outdoor gatherings.

How to choose the right accessory for your electric knife

Choosing the wrong accessory is a waste of time and money. Start by noting the blade length in inches and the mounting style. Check whether the manufacturer recommends OEM parts; sometimes non-branded blades work just as well, but you’ll want to read user reviews and check return options.

Match the mounting mechanism

Mounting mechanisms vary. Some knives use a simple slot-and-lock system, while others have proprietary fittings. If the product listing doesn’t show the mount type, contact the retailer or check user forums. It’s like finding the right key for a lock — the fit has to be precise or the blade won’t operate safely.

Consider intended use

Ask yourself what you slice most. If you carve roast beef and joints, straight blades are a must. For bagels and artisan breads, pick serrated blades. If you expect to switch tasks often, see if the knife accepts multiple blade types so you can swap blades quickly without tools.

Tips for maintaining and getting the most from your electric knife

Maintenance extends the life of both blade and motor. Clean and dry blades after each use, check for wear in the mounting points, and store blades in a sheath to avoid nicks. Replace blades when they show visible dulling rather than waiting until they stop cutting — dull blades force the motor to work harder, shortening its lifespan.

Cleaning safely

Always unplug or remove the battery before cleaning. Use a small brush to remove crumbs from between the teeth, then wipe with a damp cloth. Never soak the motor housing; water and electrical components do not mix. Think of the blade as a sharp instrument that needs careful handling — you wouldn’t dunk a laptop in water, and the same respect applies here.

Sharpening vs replacement

Some blades can be sharpened, but often it’s more cost-effective to buy a replacement. Sharpening serrated blades requires special tools, so replacements are common. If you prefer sharpening, look for services that handle serrated edges, or purchase sharpening tools designed for serrations measured in inches.

Where to find the best deals, warranties and advice

Comparing prices and warranties saves money and stress. Large retailers like John Lewis and Currys sometimes bundle accessories with warranty coverage, while marketplaces such as Amazon and Wayfair let you compare multiple sellers at once. Look for retailers that provide clear compatibility information and decent after-sales support, especially when you buy non-OEM parts.

Seasonal sales and bundles

Keep an eye on seasonal sales — summer barbecues, Black Friday, and Boxing Day often bring good deals. Bundles that include a blade and a maintenance kit offer immediate value, especially if you’re replacing more than one item. Remember to verify the blade length in inches in every deal; a cheaper price isn’t worth the hassle of a wrong fit.

Sustainability and eco-friendly options

If you care about waste, choose higher-quality blades that last longer or shops that offer blade recycling. Some retailers partner with recycling schemes for metal parts, while others sell blades made from sustainably sourced steel. Consider buying one durable blade over multiple cheap replacements — it’s better for your wallet and the planet.

Final words before you buy

Buying the right electric knife accessory doesn’t have to be a chore. Start by identifying blade length in inches, the mounting style, and your typical use cases. Then compare trusted UK retailers — John Lewis, Argos, Currys, Lakeland, Amazon UK, Robert Dyas, Wayfair, and Homebase are all solid places to look. Read product descriptions carefully, check user reviews, and consider maintenance kits to keep your knife performing like new. A little research goes a long way: think of it as tuning an instrument so it plays perfectly each time you pick it up.

Conclusion

Electric knife accessories are small investments that deliver big returns: sharper slices, safer handling, and extended product life. Whether you’re replacing a worn blade, buying a spare battery, or investing in a proper storage case, the UK market offers plenty of reputable options across high-street and online retailers. Match specifications in inches, choose quality over the cheapest price, and keep a maintenance kit on hand. With the right accessories and a bit of care, your electric knife will slice like new for years.
