Best Cartridge Razors UK 2026 — Top 5 Tested Picks
Published on Tuesday, 21 July 2026
Short answer: the Gillette Fusion5 shaves closest, the Gillette SkinGuard Sensitive is the one to pick if you get razor bumps, and the BIC Hybrid 5 Flex is the cheapest to keep running at under £1.30 a cartridge. Cartridge razors remain the easiest way to get a reliable, quick shave in the UK — from rushed weekday mornings to careful weekend grooming. In this 2026 round-up we compare five standout cartridge models commonly found at Boots, Superdrug, Tesco and online retailers: Gillette Fusion5, Wilkinson Sword Hydro 5, BIC Flex 5 Hybrid, Harry's Razor and Gillette SkinGuard Sensitive. Each model brings a different balance of close shave, comfort and running cost. The Gillette Fusion5 stands out for its protective lubrication and consistent blade alignment; Wilkinson Sword's Hydro 5 focuses on hydration for sensitive skin with its gel reservoir; Harry's offers a well-balanced head and a popular subscription option; BIC presents excellent value with an adaptive flexible head; while Gillette SkinGuard adds a protective bar between the blades to calm irritation-prone skin. We factored in blade longevity, pivot action, lubricating strips, cartridge interchangeability and how tolerant each razor is of the UK's varied shower temperatures and water hardness. Practicalities matter: cartridge availability, refill price per month, recycling options and whether a razor plays well with a preshave routine and shaving products were included. Our aim is to help you pick a razor that fits your skin type, budget and grooming habits — whether you shave daily, maintain a beard line or prefer an occasional clean-up. Below you'll find a concise rundown of strengths and trade-offs for each razor, plus shopper tips for getting the best value in the UK market.
Top Picks Summary
Gillette Fusion5 Razor
The Gillette Fusion5 remains the benchmark in 2026 for precision and availability across UK retailers thanks to its five-blade layout, precision trimmer and lubricating strip that deliver consistently close shaves. It commands a premium price compared with BIC and Harry's but justifies that cost with broad blade availability, proven longevity and the most aggressive close-shave performance among the group, making it the go-to choice for users prioritising finish over savings or extreme skin sensitivity.
£8 – £15
Wilkinson Sword Hydro 5 Razor
Wilkinson Sword Hydro 5 earns its place for combining strong hydrating technology with competitive pricing for UK shoppers, using a gel-reservoir and skin-protecting features that reduce tug and irritation. Technically it sits between the Fusion5’s raw closeness and the SkinGuard’s sensitivity-first design, offering a value-heavy alternative to Gillette while typically costing less per blade in high-street and supermarket channels.
£6 – £14
BIC Flex 5 Hybrid Razor
The BIC Flex 5 Hybrid stands out in 2026 as the budget-friendly option that still offers five-blade performance, giving price-conscious buyers the best cost-per-shave among the five. Financially and technically it undercuts both Gillette and Wilkinson Sword by delivering decent performance in a simpler package — fewer premium frills but excellent value for anyone who wants capable shaving without a subscription or high blade costs.
£4 – £10
Harry's Razor
Harry’s holds a top slot for its balanced build quality, straightforward subscription model and mid-market pricing that undercuts premium brands like Gillette while delivering a noticeably better handle and finish than disposables. Its direct-to-consumer approach brings steady savings vs traditional retail prices, making it an attractive compromise between the cheap BIC option and the higher-cost Fusion5 for UK buyers seeking convenience and consistent blade supply.
Gillette SkinGuard Sensitive Razor
The Gillette SkinGuard Sensitive is the specialist pick for irritation-prone skin, thanks to its SkinGuard technology that sits between blades to reduce pressure and razor burn — a technical advantage not offered by the standard Fusion5 or many budget razors. While it carries a premium similar to other Gillette lines, the targeted clinical benefit for sensitive users often outweighs the extra cost compared with Wilkinson, BIC or generic cartridges, making it the smart choice for those whose primary concern is comfort rather than the absolute closest shave.
Multi-blade cartridges for a closer shave, lubricating strips to reduce irritation, pivoting heads for contouring, low-cost refill and subscription options, and wide retail availability across Boots, Superdrug, supermarkets and online marketplaces.
Understanding Cartridge Razors and Their Benefits
Cartridge razors trade the low running cost of a traditional safety razor for convenience and forgiveness. Here is what actually differs between the systems on this page:
A cartridge holds its blades at a fixed, guarded angle inside a pivoting head, so it needs far less technique than an open safety razor — the main reason it remains the most common wet-shaving format in the UK.
Multi-blade cartridges cut in sequence: the leading blades tension the hair and the following blades cut it. Manufacturers describe this as delivering a closer shave, and it can cut some hairs at or just below skin level.
That below-skin cut is why people prone to ingrown hairs and razor bumps are often steered towards fewer blades rather than more. Gillette's SkinGuard uses two blades separated by a guard bar instead, and Gillette reports a 12-week study showing a 61% reduction in razor-bump papules.
Lubricating strips reduce drag and typically fade or change colour as the cartridge dulls, which is the practical signal to change it — more reliable than counting a fixed number of shaves.
Running cost is driven by refills, not the handle. On UK prices in August 2026 the ladder runs roughly: BIC Hybrid 5 Flex under £1.30 a cartridge, Gillette SkinGuard from about £1.40, Wilkinson Sword Hydro 5 about £1.85, Harry's about £2.50 ordered direct, and Gillette Fusion5 anywhere from £2.10 to £3.15 depending on whether you pay Boots' £25 for a pack of eight or shop around.
Cartridges are only cross-compatible within a brand's own system — a Fusion5 cartridge will not fit a Hydro 5 or a Harry's handle — so check the handle you already own before buying refills.
Frequently Asked Questions
Which cartridge razor gives the closest shave?
The Gillette Fusion5. It runs five anti-friction blades plus a rear precision trimmer and holds the highest rating on this page at 4.6. It is also the most expensive of the five to keep running, at roughly £2.10 to £3.15 per cartridge in the UK depending on where you buy the refills.
What does the Wilkinson Sword Hydro 5 do during shaving?
It carries a hydrating gel reservoir above the blades that releases moisture as you shave, instead of the thin lubricating strip used on most cartridges, which keeps the glide going on a longer stroke. It has five blades with shock-absorb mounting and averages 4.4.
Is the BIC Flex 5 Hybrid better value than the Gillette Fusion5?
On running cost, clearly yes. A BIC handle bundled with 10 refills is about £13.95 on Amazon.co.uk, under £1.30 a cartridge, while an 8-pack of Fusion5 refills is £25.00 at Boots and around £17 from the cheapest UK sellers. The Fusion5 shaves closer and its refills are stocked almost everywhere; the BIC is the one to buy if cost per shave is the deciding factor. Note that BIC sells it in the UK mainly under the name Hybrid 5 Flex.
How much does a cartridge razor cost to run in the UK?
Budget by the cartridge, not the handle. At August 2026 UK prices that is roughly £1.30 for BIC, £1.40 for Gillette SkinGuard Sensitive, £1.85 for Wilkinson Sword Hydro 5, £2.50 for Harry's ordered direct, and £2.10 to £3.15 for Gillette Fusion5. A cartridge typically lasts one to three weeks of daily shaving, so the gap between the cheapest and dearest system here works out at a few pounds a month rather than a few pence.
Conclusion
Cartridge razors remain a practical, widely available option across the UK in 2026. The right choice depends on your skin sensitivity, shaving frequency and whether you prioritise low running costs or premium comfort. If irritation is a concern, favour models with thicker lubricating strips and fewer pulls per stroke — the Gillette SkinGuard and Wilkinson Sword Hydro 5 are good places to start. For budget-conscious shoppers, compare refill prices — Harry's subscription often unlocks savings, while BIC and supermarket own-brand deals can be the cheapest short-term option. We recommend buying a small pack to try for a fortnight, checking compatibility with your existing handles, and signing up for recycling schemes where offered. If you want a personalised suggestion, use the search bar or filters to narrow by blade count, price-per-cartridge and skin type.
