Mobile Phone Screen & Back Protectors price comparison UK
Screen protectors sit at an odd crossroads: they're one of the cheapest accessories you can buy for your phone, yet choosing the wrong one can leave your display looking washed out, your touch sensitivity sluggish, or — worse — your edges completely unprotected after a single drop. With 3,148 products listed here, ranging from 6 £ for basic film protectors up to the premium end of the market, the choice is far from trivial.
The market is dominated by a handful of specialists. 3MK accounts for over half the catalogue with more than 1,500 references — a sign of their breadth across virtually every handset model. PanzerGlass is the brand most often recommended by tech reviewers like TechRadar and Trusted Reviews, particularly for iPhone users, thanks to their EasyAligner installation system that genuinely reduces bubble-related frustration. Belkin and ZAGG round out the mainstream options, while Spigen tends to attract buyers who already use their cases and want guaranteed compatibility.
Tempered glass remains the go-to choice for most people — 9H hardness ratings are now standard at even modest price points, and the tactile feel is far closer to the bare screen than older PET films. That said, don't dismiss flexible TPU protectors outright: on curved-edge devices like Samsung Galaxy S-series phones, a rigid glass protector can lift at the edges within weeks, whereas a well-fitted film stays put. Compatibility with your mobile phone case is another practical concern — Ultra-Wide Fit protectors in particular can clash with slim-fit cases.
One trend worth noting: anti-blue light variants, once a niche add-on, now appear across the PanzerGlass and 3MK ranges at no significant price premium. If you spend long hours on your phone, it's worth considering. Camera lens protectors — sold separately by both 3MK and PanzerGlass — are also increasingly popular as rear camera modules grow larger and more exposed. You'll find dedicated options for iPhone 13 Pro, 14 Pro Max, and the latest 15 and 16 series. Pair them with a protective case and you've covered all the vulnerable surfaces. For anything beyond protection — charging cables, spare parts — our mobile phone spare parts section has you covered.
Prices cluster tightly between 12 £ and 18 £ for the vast majority of products — which tells you that spending significantly more doesn't automatically mean better protection. It usually means a more specific fit, a premium installation kit, or a privacy filter. Compare carefully before you commit.
How to Choose the Right Screen Protector for Your Phone
Most people buy a screen protector in a hurry — grabbed at the checkout alongside a new phone. That's how you end up with a protector that lifts at the edges, kills your display brightness, or simply doesn't fit your case. Here's what actually matters, based on the products we've analysed across this catalogue.
Tempered glass vs. flexible film — know which suits your device
Tempered glass (typically 0.3–0.5 mm thick, rated 9H hardness) offers superior scratch resistance and a premium feel, but it's rigid. On flat-screen phones — most iPhones, many mid-range Androids — it's the obvious choice. On curved-edge devices like the Samsung Galaxy S or Z series, a rigid glass protector will almost certainly lift at the edges over time. For those handsets, a high-quality TPU or hybrid film is the more practical option, even if it feels slightly less premium. Don't let marketing override physics.
Screen coverage: Classic Fit vs. Ultra-Wide Fit
Classic Fit protectors leave a small border around the screen edge — they're easier to install and more compatible with most cases. Ultra-Wide Fit protectors extend closer to the very edge of the display, offering better protection against edge impacts but potentially clashing with thicker cases. PanzerGlass's Ultra-Wide Fit range is excellent, but check your case compatibility first. If you use a slim or no case, Ultra-Wide is worth the marginal extra cost.
Installation system — more important than it sounds
A misaligned protector with air bubbles is worse than no protector at all. Brands like PanzerGlass include an EasyAligner frame that positions the glass perfectly before you press it down — it makes a genuine difference, especially on larger phones like the iPhone 14 Plus or 15 Pro Max where manual alignment is fiddly. Budget protectors with no alignment guide are a gamble. If you've ever ruined a protector on installation, pay the small premium for an assisted system.
Anti-blue light filtering — worth it for heavy users
Anti-blue light screen protectors block roughly 30–50% of high-energy blue light, which can contribute to eye strain during prolonged use. The visual trade-off is a slight warm tint to the display — noticeable on white backgrounds. PanzerGlass offers anti-blue light variants for iPhone 14 Pro and 14 Plus at prices comparable to their standard range. If you use your phone heavily in the evenings, it's a sensible upgrade. If colour accuracy matters to you (photography, video), stick with a standard clear protector.
Camera lens protection — don't overlook it
The rear camera module is often the most expensive component to replace on a modern smartphone. Dedicated lens protectors from 3MK and PanzerGlass (such as the PicturePerfect range for iPhone 13 Pro) use optically clear coatings that don't degrade photo quality. They're typically priced well below 12 £ and are genuinely worth adding to your order. A scratched lens is permanent — no software update fixes it.
Pack size and value
Single-piece packs are standard, but some brands (particularly 3MK with their ARC+ range) offer multi-pack options. If you're prone to cracking or replacing protectors, a two- or three-piece pack works out considerably cheaper per unit. Check the pack contents carefully — product listings don't always make this obvious, and a "1 pc(s)" listing at a higher price isn't always better value than a twin pack from a lesser-known brand.
- Budget picks (From 6 £ to 12 £) : Basic PET film protectors and entry-level tempered glass from brands like Cadorabo and ZAGG. Functional scratch protection, but installation is typically manual with no alignment guide, and optical clarity can be noticeably lower. Fine for older or secondary devices where you're not fussed about perfection.
- The sweet spot (From 12 £ to 18 £) : This is where most of the catalogue sits, and where the best value lies. You'll find 3MK's ARC+ and Lens Protection range, PanzerGlass Classic Fit options, and Samsung's own official protectors. Solid 9H tempered glass, decent oleophobic coatings, and reasonable installation guides. The right choice for most people.
- Premium fit and features (From 18 £ to 19 £) : PanzerGlass Ultra-Wide Fit with EasyAligner, Belkin ScreenForce, and Spigen's higher-end options. You're paying for a more precise fit, better installation systems, and extras like anti-blue light or privacy filters. Worth it for flagship phones where a poor fit would be genuinely frustrating.
- Specialist and professional (Over 19 £) : eSTUFF and Smart Engineered dominate this tier — often targeting business or bulk deployment rather than individual consumers. Privacy screen protectors for sensitive environments, and multi-device packs. Unless you have a specific professional need, there's little reason to spend here for personal use.
Top products
- PanzerGlass ® Anti-blue light Screen Protector iPhone 14 Plus | 13 Pro Max | Ultra-Wide Fit w. EasyAligner (PanzerGlass) : The most-listed product in this catalogue for good reason — Ultra-Wide Fit with EasyAligner plus anti-blue light filtering is a genuinely useful combination. Best for heavy iPhone users who spend long evenings on their phone. The warm tint is noticeable; if colour accuracy matters to you, opt for the standard clear version instead.
- 3MK ARC+ 1 pc(s) (3MK) : 3MK's flexible ARC+ film is the go-to for curved-edge devices where rigid glass simply won't stay put. Self-healing properties are a genuine plus. Not as satisfying to the touch as tempered glass, but far more practical on Samsung Galaxy S-series and similar handsets. Solid value.
- PanzerGlass ® PicturePerfect Camera Lens Protector iPhone 13 Pro | 13 Pro Max (PanzerGlass) : One of the few camera lens protectors in the top listings, and it earns its place. Optically neutral coating means no degradation to photo quality — a real concern with cheaper alternatives. Essential if you use your iPhone 13 Pro without a case. Priced fairly for what it does.
- PanzerGlass SAFE. by ® Privacy Screen Protector iPhone 16 Pro Max | Ultra-Wide Fit (PanzerGlass) : The most specialised pick in this selection — micro-louver privacy technology that blocks side-on viewing. Genuinely useful for commuters and business users handling sensitive data. Be aware: the brightness reduction is significant and makes outdoor use harder. Not a casual purchase.
- Belkin ScreenForce Clear screen protector Apple 1 pc(s) (Belkin) : Belkin's ScreenForce is a reliable, no-nonsense option for iPhone users who want a trusted brand without the premium PanzerGlass price. Installation is straightforward and optical clarity is good. Not the most feature-rich protector in the range, but consistently well-regarded by buyers on John Lewis and Amazon.co.uk.

Frequently Asked Questions
What's the difference between a Classic Fit and Ultra-Wide Fit screen protector?
Classic Fit leaves a small gap around the screen edges, making it easier to install and compatible with virtually all cases. Ultra-Wide Fit extends to the very edge of the display for maximum coverage, but can lift or conflict with thicker cases. For most users with a standard case, Classic Fit is the safer choice — Ultra-Wide is best reserved for those using slim or no cases on flagship iPhones or Samsung Galaxy devices.
Is a 9H hardness rating actually meaningful?
Yes, but it's not the whole story. A 9H rating means the glass resists scratches from materials up to 9 on the Mohs scale — harder than keys, coins, or most everyday abrasives. What it doesn't tell you is impact resistance or edge protection. A 9H protector can still shatter on a corner drop. Look for additional drop-test certifications or reinforced edge designs if impact protection is your priority, not just scratch resistance.
Will a screen protector affect my phone's touch sensitivity?
A well-made tempered glass protector at 0.3–0.4 mm thickness should have no noticeable effect on touch sensitivity. Problems arise with very thick glass (0.5 mm+), poor-quality films, or protectors that aren't properly adhered — air gaps are the main culprit. If you notice sluggish touch response after fitting a protector, check for lifting edges or bubbles before assuming the product is faulty.
Should I bother with a camera lens protector as well?
For any phone with a protruding camera module — which is most flagships released in the last three years — yes, absolutely. The rear lens is unprotected by default and sits proud of the body, making it vulnerable to surface scratches when you place the phone face-up on a table. 3MK Lens Protection and PanzerGlass PicturePerfect options are priced well under 12 £ and use optically neutral coatings that won't affect photo quality. It's one of the best-value additions you can make.
Are cheap screen protectors from unknown brands worth the risk?
Generally, no — and here's why. The main failure modes of budget protectors are poor optical clarity (making your display look dim or yellow-tinted), weak adhesive that lifts within weeks, and no alignment guide that makes installation a lottery. At the prices in this category, the gap between a budget option and a reliable brand like 3MK or PanzerGlass is often just a few pounds. The frustration of a badly fitted or yellowing protector isn't worth the saving.
Do anti-blue light screen protectors actually reduce eye strain?
They can help, though the effect is modest. Anti-blue light protectors typically block 30–50% of high-energy blue light, which research suggests may contribute to eye fatigue during evening use. The trade-off is a warm colour cast that some users find distracting. A more effective approach for eye strain is using your phone's built-in Night Shift or blue light filter setting — but if you prefer a hardware solution, PanzerGlass's anti-blue light range for iPhone 14 Pro and 14 Plus offers a reasonable compromise without a significant price premium.
In 2026, is a privacy screen protector worth buying for everyday use?
Only if you regularly use your phone in crowded public spaces — commuting, open-plan offices, or travel. Privacy protectors use micro-louver technology to narrow the viewing angle, making the screen unreadable from the side. The downside is a noticeably darker display (typically 40–50% brightness reduction) and a higher price, as seen with the PanzerGlass Privacy Screen Protector for iPhone 16 Pro Max. For most people, the brightness penalty makes it impractical as a daily driver — but for those handling sensitive information on the go, it's a legitimate purchase.
