Shaver Accessories Price Comparison
Compare 133 shaver accessories from Philips, Braun & Panasonic. Find replacement heads and blades from 21 £ — updated daily.
Replacement shaver heads are one of those purchases that catches people out. You've spent good money on a quality electric razor, then six months later the shave quality drops — and suddenly you're hunting down a compatible cassette that costs nearly as much as a budget shaver. That's the reality of this market, and it's worth going in with your eyes open.
Our catalogue covers 133 accessories spanning the major players: Philips dominates in sheer volume with over 60 references, while Braun commands a noticeably higher average price point. Panasonic sits at the premium end, and Remington offers some of the most accessible entry prices. The spread is wide — from 21 £ for a basic blade up to 38 £ for a top-tier cassette system — which means there's genuine choice, but also genuine risk of overspending if you don't know what you're looking for.
The single most important thing to understand about shaver accessories is that compatibility is non-negotiable. A Braun Series 5 cassette will not fit a Series 7 handle, and a Philips SH91 head won't slot onto a Series 5000 body. Manufacturers deliberately use proprietary connectors, so always cross-reference your shaver's model number before buying. Most products list compatible models in the title or description — if they don't, that's a red flag worth heeding.
Beyond compatibility, the real question is how often you'll be replacing. Most manufacturers recommend a new head every 12 to 18 months, though heavy daily users may find performance drops sooner. At a median price of 35 £, budgeting roughly that amount per year for maintenance is a reasonable baseline. If you're comparing this to traditional razor blades, the annual cost often works out comparable — but the convenience of an electric system is what most people are actually paying for.
One pattern worth noting: Braun's Series 8 and Series 7 cassettes sit comfortably in the mid-to-upper range, yet they're among the most searched accessories on the market. Philips OneBlade replacement blades, by contrast, are consistently priced below the category median — making the OneBlade ecosystem one of the more cost-effective to maintain long-term. If you're still deciding on a shaving system rather than replacing an existing one, that running cost is worth factoring in from the start.
How to Choose the Right Shaver Accessory
Most people only think about replacement shaver heads when their shave quality has already deteriorated. Getting ahead of that — and knowing exactly what to look for — saves both money and frustration. The criteria below are ordered by the questions we see buyers get wrong most often.
Compatibility with your exact shaver model
This is the make-or-break criterion, and it's non-negotiable. Braun, Philips, Panasonic and Remington all use proprietary connectors — a Series 5 cassette won't fit a Series 7 handle, full stop. Before anything else, locate your shaver's model number (usually printed on the underside of the handle) and match it precisely. For Braun, the cassette code matters: 52S/52B for Series 5, 70S/73S for Series 7, 83M for Series 8. For Philips, the SH-prefix heads (SH71, SH91) are series-specific. Remington's SPF-300 and SPF-PF are similarly non-interchangeable. If a listing doesn't clearly state compatible models, don't risk it.
Foil vs. rotary vs. OneBlade system
The type of cutting system determines everything about the shave feel — and you can't switch systems without buying a new shaver. Foil systems (Braun, Panasonic, Remington) use oscillating blades behind a thin metal grid, delivering a close, linear shave well-suited to straight-grain stubble. Rotary heads (Philips Series 5000/7000/9000) use circular cutters that follow facial contours, better for longer or irregular growth. OneBlade is its own category — a hybrid blade that trims, edges and shaves, with replacement blades priced accessibly. Know which system you own before browsing.
Replacement frequency and annual running cost
Manufacturers typically recommend replacing heads every 12 to 18 months, though daily users on coarser hair may notice degradation sooner. Some Braun cassettes include a wear indicator strip that fades with use — genuinely useful, not just a gimmick. At 35 £ for a mid-range cassette, the annual maintenance cost is manageable, but premium Panasonic and Braun Series 8 heads push toward 37 £ and beyond. Factor this in when choosing your shaving ecosystem — a cheaper shaver with expensive replacement heads can cost more over three years than a pricier model with affordable accessories.
Number of cutting elements and shave closeness
More cutting elements generally mean a closer, more efficient shave — particularly relevant for thick or fast-growing stubble. Braun's Series 8 cassette (83M) features a multi-element system with an integrated precision trimmer, while entry-level Series 1 and 3 heads use simpler foil configurations. Philips' SH91 for the Series 9000 uses three rotary heads with individual flexing. If you shave daily and want a single-pass result, investing in a higher-element cassette pays off. For occasional shavers, a simpler head is perfectly adequate.
Washability and cleaning requirements
All the accessories in our catalogue are designed to be rinsed under running water, but there's a meaningful difference between a head that tolerates a quick rinse and one built for full submersion cleaning. Braun's cassette system is designed to work with the Clean & Charge station — if you own one, make sure your replacement cassette is station-compatible. Philips rotary heads are fully waterproof and straightforward to clean manually. Remington's foil heads are rinse-friendly but benefit from the occasional drop of shaver oil to maintain performance. Neglecting cleaning is the fastest way to shorten a head's lifespan.
- Budget picks (From 21 £ to 28 £) : Entry-level Remington foil heads and Philips OneBlade replacement blades dominate this tier. Perfectly functional for occasional shavers or those maintaining a secondary razor. Don't expect premium materials or wear indicators, but compatibility is straightforward and the value is solid.
- The sweet spot (From 28 £ to 35 £) : Most Braun Series 1 and 3 cassettes and Philips SH71 heads land here. A good balance of build quality and cost — suitable for daily shavers who want reliable performance without overspending. This is where we'd point most buyers first.
- Mid-to-upper range (From 35 £ to 37 £) : Braun Series 7 and Series 8 cassettes, plus Philips SH91 heads for the Series 9000. Noticeably better shave quality, often with wear indicators and multi-element cutting systems. Worth it if you shave daily and value skin comfort.
- Premium (Over 37 £) : Panasonic ES-LV series heads and top-tier Braun cassettes. Titanium-coated blades, micro-lubrication systems, and the closest possible shave. Justified for those who've invested in a premium shaver and want to maintain its performance — overkill for anyone else.
Top products
- Remington SPF-300 shaver accessory (Remington) : The most accessible entry point in the catalogue — solid foil replacement for Remington users on a budget, though check compatibility carefully as the SPF range covers multiple handle generations.
- Braun Series 5 52S Electric Shaver Head Replacement Cassette – Silver (Braun) : A reliable all-in-one cassette for Series 5 owners — the silver finish indicates the standard foil configuration. Good shave quality and straightforward to fit, but the price sits noticeably above entry-level alternatives.
- Braun Series 7 70S Electric Shaver Head Replacement Cassette – Silver (Braun) : The go-to replacement for Series 7 handles — multi-element foil system with a genuine improvement in shave closeness over Series 5. Worth every penny if you own the right handle; completely useless if you don't.
- Philips SHAVER Series 9000 SH91 SH91/50 Replacement electric shaver heads (Philips) : Premium rotary heads for Philips' flagship Series 9000 — individually flexing cutters deliver an excellent contour-following shave. Expensive relative to the category median, but the Series 9000 ecosystem justifies the investment for daily shavers.
- Philips Norelco OneBlade OneBlade 360 QP420/50 Replacement blade 2 pack (Philips) : The best value-per-shave proposition in the entire catalogue. Two blades in one pack, priced well below the category median — the OneBlade ecosystem is simply the most cost-effective to maintain, and this two-pack makes that case clearly.

Frequently Asked Questions
How do I know which replacement head is compatible with my electric shaver?
Check the model number printed on the underside of your shaver handle — it's the only reliable way to confirm compatibility. Braun cassettes use a series-specific code (52S for Series 5, 70S or 73S for Series 7, 83M for Series 8), while Philips heads use an SH-prefix (SH71 for Series 5000/7000, SH91 for Series 9000). Never rely on visual similarity alone — connectors look alike but are not interchangeable across series.
How often should I replace my electric shaver head?
Most manufacturers recommend replacing every 12 to 18 months under normal daily use. In practice, you'll notice the shave becoming less efficient, requiring more passes or causing more skin irritation — that's the clearest signal. Some Braun cassettes include a wear indicator strip that fades progressively; if yours has one, trust it. Waiting too long doesn't just affect shave quality — a worn foil can actually cause more skin irritation than a new one.
Are Philips OneBlade replacement blades worth buying in multipacks?
Yes, multipacks are genuinely good value for OneBlade users who shave regularly. The QP420/50 two-pack and QP620/50 bundle both come in below the per-blade cost of buying individually, and OneBlade blades typically last around four months with daily use. Stock up during Black Friday or Amazon Prime Day sales — these accessories see reliable discounts during major UK shopping events.
Can I use a third-party replacement head instead of the official brand cassette?
We'd advise against it for foil shavers. Third-party foil heads for Braun and Panasonic shavers frequently use lower-grade steel that dulls faster and can damage the inner blades — which are often sold separately and cost as much as the foil itself. For Philips rotary heads, the situation is similar. The savings rarely justify the risk, especially given that official cassettes are competitively priced in the 28 £ to 35 £ range when bought from the right retailer.
What's the difference between a shaver cassette and a shaver head?
A cassette (used primarily by Braun) is an all-in-one unit combining the foil and the inner cutting blade in a single replaceable module — you swap the whole thing at once. A shaver head (more common with Philips rotary systems) typically refers to the outer cutter and cap assembly. Some systems, particularly older Braun models, sell the foil and blade separately, which can be cheaper but requires more careful purchasing. Always check whether a listing includes both components before buying.
Is there a risk of buying a fake Braun or Philips replacement head online?
Yes, and it's more common than most people realise. Counterfeit Braun cassettes in particular circulate on third-party marketplace listings — they look identical to genuine articles but use inferior steel that dulls within weeks. Stick to buying from established UK retailers like Currys, John Lewis, or directly from brand-authorised sellers on Amazon. If a price seems significantly below 28 £ for a Series 7 or Series 8 cassette, treat it as a warning sign rather than a bargain.
Do replacement shaver heads come with any warranty?
Official replacement heads from Braun, Philips and Panasonic typically carry a manufacturer's guarantee of six to twelve months against defects. This doesn't cover normal wear — a foil that's dulled through regular use won't be replaced under warranty. Keep your proof of purchase, particularly when buying from smaller online retailers, as John Lewis and Currys both offer straightforward returns processes if a product arrives faulty.
