Wiper blades seem unremarkable until they fail mid-downpour on a motorway — a smearing, chattering, or streaking blade on a wet windscreen is both a visibility hazard and an MOT failure point. The rubber wiping element degrades from UV exposure, ozone, road film, and the abrasive effect of dry-running; most manufacturers recommend annual replacement, though UK winters with salt-laden spray can accelerate the process. Chattering — where the blade bounces across the glass rather than gliding — is typically caused by a hardened or torn wiper lip, while a film of smear left after each pass usually points to contamination of the rubber or the windscreen itself rather than a structural fault. Beam blades have largely replaced traditional multi-piece frames on post-2010 vehicles, offering more uniform contact pressure across the full arc, though they require the correct fitment adaptor to mate with the arm. Bosch leads the OEM fitment market and its replacement blades carry the same reference numbers; Valeo is the preferred factory supplier for the majority of French-built models. Confirming the OE number ensures the blade matches the correct arm attachment type, wiper length, and sweep angle for your specific vehicle.
Wiper blades are vehicle-specific in both length and arm attachment type. Use the make, model, and year selector on this page to display only the OE references TecDoc maps to your exact vehicle. Pay attention to whether your car uses hook, pinch-tab, top-lock, or side-pin arm attachments — the same blade length in the wrong fitment type simply won't seat correctly on the arm. Driver and passenger sides are often different lengths, so order both at once rather than replacing only the side that fails first.
OEM blades from suppliers such as Bosch or Valeo use the same rubber compound and spring tension profiles as the units fitted at the factory, and their OE references are identical to the vehicle builder's part numbers. Aftermarket blades from these same brands offer comparable performance at a lower price. Very cheap unbranded blades frequently use harder rubber that leaves streaks even when new, and spring pressures that are insufficient for maintaining contact at motorway speeds, where lift becomes a significant factor.
Yes, replacing both blades at the same time is good practice. Both rubber elements age from the same environmental exposure — UV, ozone, road salt — at roughly the same rate. If one blade has deteriorated to the point of streaking or chattering, the other is usually only a few months behind. Replacing as a pair also means both sides are at the same stage of wear, giving consistent clearing performance across the full windscreen sweep at the same time.
Smearing — a film of water left on the windscreen after each pass — is the most common symptom of a contaminated or hardened wiper lip. Chattering or skipping across the glass indicates the rubber has become stiff, usually from UV hardening. Squeaking on a clean, wet windscreen can mean the rubber lip has torn or inverted. Visually inspect the blade for cracks, splits, or uneven contact when pressed against the screen; any of these means replacement is overdue regardless of how recently the blade was fitted.
