Car Doors, Windows & Components Price Comparison 2026
Compare 239 car door, window & wiper blade products from Bosch, Valeo and more — find the best price across top UK retailers.
Wiper blades dominate this category, and for good reason — they're one of the most frequently replaced components on any car. With 239 products listed, the range spans from budget-friendly replacement blades starting at 4 £ right through to premium flat-blade systems pushing 29 £. What's striking when you look at the data is just how thoroughly Bosch and Valeo have carved up the market between them: Bosch alone accounts for over 100 listings, with Valeo close behind at 85. Everyone else is playing catch-up.
The Bosch Aerotwin range — particularly the AR U series — consistently attracts the most merchant competition, which is exactly what drives prices down. Seven retailers stocking the same blade means you're rarely paying over the odds if you take a moment to compare. Valeo's equivalent flat-blade offerings sit slightly higher in price on average, but they're a genuine alternative for drivers whose vehicles are factory-fitted with Valeo OEM parts. Carpoint and Hella fill out the mid-to-lower end of the catalogue, with Hella's average price sitting notably low — worth checking if you're replacing a rear wiper on a tight budget.
One thing worth flagging: this isn't a category where brand loyalty should override fitment. A Bosch blade at the wrong length is useless, full stop. Always cross-reference your vehicle's make, model, and year before buying — most retailers, including those listed on MagicPrices, provide a vehicle compatibility checker. The good news is that the Bosch AR U series uses a universal bayonet (U-hook) fitting, which covers the vast majority of European cars built in the last two decades.
Prices cluster tightly between 7 £ and 11 £ for standard single-blade replacements — this is where the bulk of the catalogue sits, and where the value is strongest. If you're replacing both front blades at once, buying a twin pack from the same range often works out cheaper than two individual purchases. For car mirrors and components, which share the same body-parts category, the price dynamics are quite different — but the same principle of checking merchant competition applies.
Dometic stands out as the outlier here, with just four products averaging around 20 £ — these are specialist components, likely for motorhomes or commercial vehicles, and shouldn't be compared directly to standard passenger car wiper blades. If you're shopping for everyday replacements, stick to the Bosch and Valeo ranges where merchant competition is highest and prices are most transparent.
How to Choose the Right Wiper Blade for Your Car
Most drivers replace wiper blades only when visibility becomes genuinely dangerous — by which point they've already been driving with compromised safety for weeks. Our data shows the sweet spot for quality replacement blades sits between 7 £ and 11 £, which makes this one of the cheapest meaningful upgrades you can make to your car. Here's what actually matters when choosing.
Blade length and vehicle fitment
This is non-negotiable. Wiper blades come in sizes from 13" up to 26" (and beyond for some vehicles), and fitting the wrong length leaves sections of your windscreen uncleared. Your driver's side and passenger's side blades are almost always different lengths — don't assume they're the same. Check your vehicle handbook or use the compatibility tool on the retailer's site. The Bosch AR U series covers sizes 13" through 26", making it one of the most comprehensive ranges available for European vehicles.
Flat blade vs. traditional framed blade
Traditional framed blades use a metal bracket to distribute pressure across the rubber — they work fine but can ice up in winter and tend to chatter at motorway speeds. Flat (frameless) blades like the Bosch Aerotwin apply pressure via an internal tensioning element, giving more even contact across the full length of the blade. They're aerodynamically cleaner and generally quieter. The trade-off? They cost more — typically from 11 £ upwards — and not every older car's wiper arm is compatible without an adaptor. Hybrid blades sit between the two: a flat rubber profile inside a partial frame, offering a reasonable compromise.
Connector type compatibility
Even a perfectly sized blade is useless if the connector doesn't fit your wiper arm. The most common fitting in the UK is the bayonet hook (U-hook), which is what the Bosch AR U series uses. Other types include the J-hook, pin-top, and side-pin — less common but still found on plenty of Ford, Vauxhall, and Renault models. Some premium blades come with a multi-adaptor kit; budget blades often don't. If you're unsure, check the existing blade before ordering.
Rubber compound and weather resistance
The quality of the wiper rubber determines how long the blade lasts and how cleanly it wipes. Natural rubber degrades faster under UV exposure and ozone — a real issue in the UK where cars often sit outside for months. Synthetic rubber and graphite-treated compounds last longer and glide more smoothly. At the budget end (below 7 £), you're typically getting basic natural rubber with no surface treatment. From 7 £ to 11 £, you start to see graphite-coated and synthetic options. Anything above 11 £ should offer proper anti-ozone treatment and a rated lifespan of at least 18 months.
Noise and streak performance
A wiper blade that squeaks or leaves streaks isn't just annoying — it's a sign the rubber is no longer making proper contact with the glass. This usually happens when the blade has hardened (cold weather), when the windscreen has a silicone film from a water-repellent treatment, or when the blade is simply worn out. High-quality blades with uniform contact pressure and a treated rubber compound are significantly less prone to both issues. If you've recently applied a Rain-X or similar product to your screen, make sure the blade rubber is compatible — some compounds react badly with hydrophobic coatings.
- Budget replacements (From 4 £ to 7 £) : Basic framed blades from Hella and Champion. Fine for rear wipers or infrequent-use vehicles. Expect standard natural rubber, no surface treatment, and a lifespan of around six months in typical UK conditions. Not what we'd recommend for your main front wipers.
- The sweet spot (From 7 £ to 11 £) : This is where the Bosch AR U series lives, and it's genuinely excellent value. Flat-blade design, graphite-treated rubber, universal U-hook fitting. Most drivers replacing standard front or rear blades should start here. Valeo's equivalent range also appears at this level.
- Mid-range premium (From 11 £ to 20 £) : Valeo's higher-spec flat blades and Bosch Aerotwin twin packs. Better rubber compounds, longer rated lifespan (up to two years), and often sold as vehicle-specific kits. Worth it if you do high mileage or drive frequently in heavy rain.
- Specialist and OEM-grade (Over 20 £) : Dometic and OEM-equivalent products for specialist vehicles, motorhomes, or commercial applications. Also where you'll find complete wiper system kits. Overkill for a standard passenger car — but if your vehicle demands it, don't cut corners here.
Top products
- Bosch AR 22 U Wiper blade (Bosch) : The 22-inch size covers one of the most common driver-side fitments on European cars — and with seven merchants competing on price, this is consistently one of the best-value blades in the catalogue. Flat-blade design, U-hook fitting, graphite-treated rubber. Our top pick for most drivers.
- Bosch AR 19 U Wiper blade (Bosch) : A popular passenger-side size that pairs well with the AR 22 U. Same Aerotwin flat-blade construction, same strong merchant competition. If you're replacing both front blades, this and the AR 22 U are a natural pairing for many mid-size European cars.
- Bosch Aerotwin AR 17 U Wiper blade (Bosch) : The 17-inch size is the go-to rear wiper replacement for a wide range of hatchbacks and SUVs. Slightly fewer offers than the front-blade sizes, but still well-priced. Excellent if your rear wiper has been neglected — most drivers replace front blades and forget the rear entirely.
- Valeo 1913327 car door, window / component Wiper blade (Valeo) : Sits at a higher price point than the Bosch AR U equivalents, which is only justified if your vehicle was originally fitted with Valeo wipers. For everyone else, the Bosch range offers comparable performance at a lower price. That said, Valeo's rubber compound quality is genuinely first-rate.
- Bosch AR 26 U Wiper blade (Bosch) : The longest blade in the AR U series — needed for larger vehicles including some SUVs, MPVs, and estate cars. Seven offers keep the price competitive. If your car takes a 26-inch driver-side blade, options are more limited than for smaller sizes, making this a particularly strong listing.

Frequently Asked Questions
How do I know which wiper blade size fits my car?
Check your vehicle handbook — it lists the correct blade length for both driver and passenger sides. Alternatively, most online retailers and parts sites have a vehicle registration lookup tool that returns the exact sizes for your make, model, and year. Don't guess: driver and passenger blades are almost always different lengths, and even a 1-inch mismatch can leave a significant unwiped strip on your windscreen.
Are Bosch Aerotwin blades worth the extra cost over standard framed blades?
For most drivers, yes — particularly if you do regular motorway driving. The flat-blade design eliminates the metal frame that can ice up in winter and cause chatter at speed. Bosch Aerotwin blades apply pressure more evenly across the full blade length, which means fewer streaks and less noise. The price difference between a basic framed blade and an Aerotwin is modest at this end of the market, making the upgrade straightforward to justify.
How often should wiper blades be replaced?
Every 12 to 18 months is the standard recommendation, though UK conditions — frequent rain, UV exposure in summer, frost in winter — can accelerate wear. A reliable indicator is performance: if your blades are streaking, squeaking, or skipping across the screen, replace them immediately rather than waiting for a scheduled service. Don't wait until your MOT tester flags them.
Can I fit a flat wiper blade to any car?
Not always. Flat blades require a compatible wiper arm connector — most modern European cars use the U-hook (bayonet) fitting that the Bosch AR U series is designed for, but older vehicles and some Asian models use different connectors. Some flat blades come with a multi-adaptor kit; others don't. Check the connector type on your existing blade before buying, or use a fitment guide. Forcing an incompatible connector is a common and avoidable mistake.
Is it worth buying cheap wiper blades from an unknown brand?
Generally, no — and this is one category where we'd actively steer you away from the very cheapest options. A wiper blade that streaks or skips in heavy rain is a genuine safety issue, not just an inconvenience. The difference in price between a no-name blade and a Bosch or Valeo equivalent is often just a few pounds, but the performance gap is significant. Hella and Champion at the budget end are at least established automotive suppliers with quality standards; truly unknown brands are a gamble we wouldn't take on something this safety-critical.
What's the difference between Bosch and Valeo wiper blades in 2026?
Both are OEM-grade suppliers — Bosch and Valeo manufacture wiper systems for major car manufacturers, so both brands are genuinely high quality. The practical difference comes down to fitment: some vehicles are factory-fitted with Valeo systems, and replacing like-for-like can sometimes give marginally better results. For most drivers, the choice comes down to price and availability. Our data shows Bosch has broader range coverage and more merchant competition, which tends to mean better prices. Valeo's higher-spec blades sit slightly above Bosch equivalents in price but are worth considering for vehicles where Valeo is the OEM supplier.
Do wiper blades affect my MOT?
Yes — a wiper blade that fails to clear the windscreen adequately is an MOT failure point. Specifically, testers check that wipers clear the windscreen effectively across the driver's required field of vision. Worn, streaking, or split blades can fail this check. Given that replacement blades cost from 7 £, it makes no sense to risk a retest fee. Replace them before your MOT if there's any doubt.
