Mercedes GLS windscreen price, by year

Price variation is driven primarily by ADAS calibration complexity — all current GLS variants carry the full Driver Assistance suite with stereo camera, so calibration is a consistent element across the range. Additional factors include acoustic glass composition and the sensor-heated zone system integration. Specialist workshop time for static calibration is factored into quotes, reflecting the precision required for Mercedes safety systems.

Had to replace the windscreen on our 18 year old car

Had to replace the windscreen on our 18 year old car because it had become dangerous due to thousands of micro chips. The low winter sun made it impossible to see out of. Searching online found UK Car Glass. The price was reasonable and I made an online booking for 2 days later. Unfortunately due to storms a nice lady from the company phoned me and asked if we could postpone fitting for 2 days till the weather cleared which was no problem. The fitter turned up as promised and the job was done within half an hour. Overall a good experience. UK Car Glass appear to be a nationwide company who sub contract to existing windscreen fitting companies. In view of this it may be worthwhile directly contacting a local firm first to check their pricing as it's possible they may be a bit cheaper because their won't be a middleman. However, I've no complaints. Ease of booking, communication etc is excellent.

Very happy with UK car glass

Very happy with UK car glass. They offered the lowest quote and an online booking service. After an initial confirmation email, I heard nothing further for a week, so I called to check that my car was still booked in for a new windscreen. I was informed that it was and they would be in touch to confirm the ETA. The team kept me informed over the weekend, the technician called and updated me again on the day, and arrived when he said he would. The screen was changed efficiently and the technician was polite and helpful. I would use the company again and recommend UK car glass to others.

What to expect during your Mercedes GLS windscreen replacement

Booking your GLS windscreen replacement through UKCG involves a simple, guided process from quote to fitting day.

  1. 1

    Complete a quick online quote using our widget — answer a few questions about your GLS variant and receive an instant price.

  2. 2

    Review and confirm your booking in under two minutes, choosing your preferred fitting date and location.

  3. 3

    Our parts team performs a detailed specification check to confirm your glass matches your factory build — camera bracket, acoustic layer, HUD surface, heated zones and all.

  4. 4

    You're matched with an approved specialist in your area. Because your GLS requires post-fit ADAS calibration, the fitting is scheduled at a workshop (not mobile) so calibration targets and diagnostic equipment are available.

  5. 5

    On fitting day, your specialist removes the old windscreen, transfers the camera bracket trim, fits your new glass with the correct encapsulation gasket, and performs static calibration indoors — typically completed within a couple of hours.

  6. 6

    Your fitter confirms the minimum drive-away time before you leave, and your two-year parts and workmanship warranty begins.

All work comes backed by a two-year warranty covering glass quality and fitting integrity.

Mobile fitting or workshop visit for your GLS?

Your GLS windscreen must be fitted at a workshop rather than mobile at your home, because all current variants require static camera calibration after replacement. This calibration uses precision target boards and diagnostic tools in a controlled indoor environment — it cannot be done on a driveway.

UKCG's no-split rule ensures your specialist fits the glass and completes calibration in a single visit, keeping you accountable for the safety-critical ADAS realignment. Mobile fitting is not available for this model.

We confirm the specific answer for your vehicle when you book.

What features does your GLS have?

Tap a feature to see what it is, how to spot it on your car, and how it affects glass replacement. We confirm the exact match for your vehicle when you book.

  • Acoustic (Noise reduction)2
    2019–2026

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026.

    What it means

    A specialised laminate interlayer dampens road and wind noise, creating a quieter cabin — a hallmark of luxury GLS ownership.

    On your Mercedes GLS

    Fitted to all current GLS windscreens; look for the 'Acoustic' or 'SoundScreen' marking on your existing glass.

  • Bracket For Safety Features2
    2019–2026Calibration varies by vehicle

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; calibration varies by vehicle.

    The moulded trim that surrounds your camera and sensor cluster at the top of the windscreen, typically transferred or supplied with replacement glass.

    What it means

    A bracket for safety features is the moulded plastic or composite shroud that sits at the top of the windscreen, framing and protecting the camera and sensor cluster mounted behind the rear-view mirror. This trim cover houses forward-facing driver-assistance cameras and sensors — equipment that monitors the road ahead for lane-keeping, collision warning, adaptive cruise control, and similar safety functions. The bracket itself is part of the vehicle's structural frame, but the trim cover you see is what protects and aesthetically integrates the technology into the windscreen area.

    How to tell

    Look at the top centre of your windscreen, just above or around the rear-view mirror. If you see a dark moulded shroud or trim panel — often rectangular or tapered — with a visible lens or sensor window, your vehicle has a bracket for safety features. Your service history or handbook will list any ADAS (Advanced Driver Assistance System) technologies fitted. Ask your dealer or service centre if your vehicle has forward-facing cameras or sensors; if it does, you have a bracket for safety features.

    Replacement impact

    On windscreen replacement, the trim cover is typically transferred from your old glass to the new one, or supplied pre-integrated with the replacement depending on the variant. This means minimal disruption to your safety system during the swap. However, if the bracket requires recalibration after glass replacement — which depends on your specific vehicle and camera type — the job may require static calibration (using a target board) or dynamic calibration (a road drive). We confirm the exact calibration procedure when we look up your vehicle.

  • Camera2
    2019–2026Calibration varies by vehicle

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; calibration varies by vehicle.

    A camera mounted near the rear-view mirror monitors the road ahead for lane-keep and traffic-sign features.

    What it means

    A forward-facing camera positioned in the windscreen header area (typically mounted on or near the rear-view mirror bracket) captures video of the road ahead. This camera feeds data to driver-assistance systems such as lane-departure warning, lane-keep assist, autonomous emergency braking, and traffic-sign recognition. The camera is a core component of modern ADAS (Advanced Driver Assistance Systems) and requires precise alignment after windscreen replacement to ensure these safety features function correctly.

    How to tell

    Look for a small dark triangular or lens-shaped component mounted in the black plastic trim area above the windscreen, typically centred near the rear-view mirror or slightly to one side. Your vehicle's handbook or infotainment menu may reference 'Lane Assist', 'Traffic Sign Recognition', or 'Autonomous Emergency Braking'. Ask your dealer or service centre directly if your car is equipped with a forward-facing camera system.

    Replacement impact

    Windscreen replacement on camera-equipped vehicles requires calibration of the camera system after the new glass is fitted. The exact calibration procedure—whether static (using a target board in a controlled environment) or dynamic (road-based)—varies by vehicle make, model, and year. We confirm the precise calibration requirement when we look up your specific vehicle. Calibration ensures lane-keep, sign recognition, and emergency-braking systems function safely. This may extend the fitting schedule and may necessitate workshop-based fitting rather than mobile attendance.

  • Green2
    2019–2026

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026.

    Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.

    What it means

    Green tint is a light-filtering coating applied to the glass during manufacture. It absorbs and reduces transmission of certain wavelengths of light, primarily to cut glare from sunlight and reflections. The tint is subtle — often barely visible to the naked eye — but measurably improves visual comfort during prolonged driving, particularly in bright conditions. It's a factory specification chosen by the vehicle manufacturer to balance daylight comfort with interior visibility and aesthetic consistency across all glass in the vehicle.

    How to tell

    The easiest way to check is to roll your side window halfway down and hold a piece of white paper behind it. Look carefully for a tint cast — green tint will appear as a subtle green hue compared to clear glass. Your windscreen will have the same tint as your side windows. You can also ask your vehicle's dealership or service centre — they'll have the original specification on file.

    Replacement impact

    Green-tinted replacement glass must match the original tint specification to maintain visual consistency across all windows and preserve the vehicle's interior aesthetics. Aftermarket OE-equivalent (OEE) green-tinted glass is widely available, though some vehicles may require original equipment (OEM) dealership glass if the tint specification is proprietary. Tint does not affect calibration, cure time, or installation procedure — it's a cosmetic and functional specification only.

  • Heated Windscreen2
    2019–2026

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026.

    What it means

    A mesh of thin wires bonded into the glass delivers rapid defrost and demisting, particularly useful in cold mornings and winter driving.

    On your Mercedes GLS

    Standard across all current GLS variants in our catalogue.

  • Heated Wiper Rest Area2
    2019–2026

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026.

    Heating elements embedded in the glass melt ice from your wipers and the bottom of your windscreen.

    What it means

    A heated wiper rest area uses electric heating elements embedded into the windscreen in the area where your wipers park when not in use. These elements warm the glass to prevent ice and frost from bonding to the wiper blades and the lower windscreen edge during cold weather. This reduces the effort needed to clear ice in the morning and helps protect your wipers from damage caused by frozen adhesion to the glass.

    How to tell

    Check your windscreen's lower edge where the wipers rest — you may see faint heating lines or elements visible in the glass. Your handbook or service history will confirm the feature. You can also ask your dealer or service centre whether your vehicle is equipped with a heated wiper rest area.

    Replacement impact

    When replacing a windscreen with a heated wiper rest area, the replacement glass must include the heating elements. Aftermarket and OE glazing suppliers offer this feature, but availability varies by vehicle. The heating system does not require calibration after replacement, though the technician will ensure the heating element connections are properly restored during installation.

  • HUD - Head Up Display2
    2019–2026No calibration after replacement

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; no calibration after replacement.

    What it means

    Your speedometer and navigation information are projected directly onto the windscreen, keeping your eyes on the road without glancing at the dashboard.

    On your Mercedes GLS

    Standard on all current GLS variants; the glass includes a special projection surface that's preserved during replacement.

  • Rain Sensor2
    2019–2026No calibration after replacement

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; no calibration after replacement.

    What it means

    Detects moisture on the windscreen and triggers automatic wiper operation, eliminating the need to switch wipers on and off manually.

    On your Mercedes GLS

    Standard on all current GLS models — confirmed during your quote.

  • Sensor Heated Zone2
    2019–2026Calibration varies by vehicle

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; calibration varies by vehicle.

    What it means

    Heating elements around the sensor cluster at the top of the windscreen prevent frost and moisture from interfering with camera and radar operation.

    On your Mercedes GLS

    Integrated into all current GLS windscreens as part of the ADAS support system.

  • Static Camera Calibration Process2
    2019–2026Static calibration required

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; static calibration required.

    What it means

    After windscreen replacement, your twin cameras must be realigned using printed target boards in a controlled workshop environment to restore lane-keeping and collision-warning accuracy.

    On your Mercedes GLS

    Required on all current GLS models; your specialist schedules this at a workshop immediately after the glass is fitted, as part of a single booking.

  • Stereo Camera2
    2019–2026Calibration varies by vehicle

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026; calibration varies by vehicle.

    What it means

    Twin forward-facing cameras in the black sensor field enable advanced ADAS functions like lane-keeping, pedestrian detection, and traffic-sign recognition.

    On your Mercedes GLS

    Standard on all current GLS variants from 2019 onwards — confirmed during the quote process as part of your ADAS specification.

  • Vin Notch2
    2019–2026

    On the Mercedes GLS: fitted on every one of the 2 windscreen variants we list; model years 2019–2026.

    A printed VIN reference box along the bottom edge of your windscreen helps identify your vehicle's chassis number at a glance.

    What it means

    A VIN (Vehicle Identification Number) notch is a small printed or etched box positioned along the lower edge of the windscreen that displays your vehicle's chassis number. This reference marking is a manufacturing and administrative feature, allowing quick visual identification of the vehicle without needing to consult documents. It's particularly useful for service records, insurance claims, and vehicle registration purposes. The notch itself doesn't affect the structural integrity or safety performance of the glass.

    How to tell

    Look along the bottom edge of your windscreen — typically in one of the lower corners — for a small rectangular box containing printed digits or characters. If you're uncertain, check your vehicle's service handbook or ask your dealership or service centre to confirm whether your model includes this feature.

    Replacement impact

    When your windscreen is replaced, the new glass will retain the VIN notch printed or etched by the manufacturer. This is a standard feature on replacement windscreens for compatible vehicles and requires no additional work or adjustment. The notch does not affect glass fitting, cure time, or any post-replacement calibration procedures.

About the Mercedes GLS

The Mercedes GLS is a full-size luxury SUV that arrived in 2019 and continues in production today, offering a commanding driving position and high-tech interior. All current variants in our catalogue feature advanced windscreen technology including acoustic glass for noise reduction, heated zones for sensor protection, and full ADAS capability with stereo camera systems.

Your GLS windscreen integrates multiple safety and comfort features: a forward-facing stereo camera for lane-keeping and collision warning, heated elements across the glass and wiper rest area, rain sensor for automatic wipers, and a head-up display projection surface. The acoustic interlayer reduces road noise while the green tint is standard across the range.

After replacement, static camera calibration is a required specialist procedure to restore ADAS function — this is carried out indoors at a workshop with precision alignment targets, ensuring your lane-keep assist and forward-collision warning work safely.

Frequently asked questions

The questions customers ask us most often.

You don't need to know. Our online widget asks a few quick questions — make, model, year, and a couple of feature details — to narrow the variant down. Once booked, our parts check team verifies the exact specification against your VIN before the job is dispatched.

Almost always, yes, where a forward-facing camera is fitted. The technicians in our network include ADAS-calibration-certified specialists — we confirm whether your job needs a workshop or can complete on your driveway when we book.

Your replacement glass matches your original factory specification — same size, features and trim fitment as the glass the car left the factory with. It's UK-approved for the road and typically supplied by tier-1 manufacturers like Pilkington, Saint-Gobain, and AGC.

OEM-branded glass (with the vehicle-maker logo) is available on request at a higher price.

Most windscreen replacements happen at your chosen location — home, office, or car park. Some jobs are better suited to a workshop — for example, windscreens with ADAS cameras needing static calibration, or where access to power, shelter, or controlled conditions makes the work safer indoors. We let you know when we confirm your booking.

Most windscreen replacements take 45–90 minutes of the technician's time. ADAS calibration extends the technician's time on the job, but cure time runs in parallel — so it doesn't usually delay when you can drive. Your technician will confirm exact timings on the day.

Most UK comprehensive policies include glass cover, typically with an excess of £75–£100. If your insurer is on our approved list, the specialist you're matched with bills them directly and you just pay the excess.

Otherwise you can pay UK Car Glass directly and claim back from your insurer — our all-inclusive price is often lower than the excess anyway, so paying direct can work out cheaper.

Two years on workmanship defects — water leaks, wind noise, bonding failures — from the date of replacement. If the specialist's work isn't right, we arrange to put it right under the warranty process.

All current GLS models carry forward-facing stereo cameras that are part of your Driver Assistance suite. After windscreen replacement, these cameras must undergo static calibration — a precision procedure using printed alignment targets and diagnostic equipment in an indoor workshop environment.

This calibration is safety-critical: your lane-keeping assist and collision-warning systems depend on it. UKCG schedules the full job (fitting + calibration) at one workshop location to ensure the work is completed correctly and you're fully protected.

Your GLS windscreen has a moulded trim cover that surrounds the camera cluster at the top, just around the rear-view mirror. During replacement, your specialist removes this trim from the old glass and transfers it to your new windscreen — or supplies it integrated with the new glass depending on the variant.

The bracket itself (which holds the cameras and sensors) stays on the vehicle; only the glass and trim are replaced. After the new glass is fitted, the bracket is recalibrated as part of the static calibration process.

Windscreen replacement on your GLS typically takes longer than standard jobs because static calibration is included. Your specialist will complete the fit and calibration within a couple of hours on the day, though exact timing depends on your specific variant and the fitter's equipment.

Calibration runs in parallel with adhesive cure, so it doesn't extend your drive-away time — your fitter will confirm the minimum wait time before you leave.

Acoustic laminate is genuinely effective at dampening noise. The interlayer absorbs vibrations from road and wind sound before they reach the cabin, delivering a noticeably quieter driving experience — particularly on motorways and in heavy traffic.

Your replacement glass will match your original factory specification, so the acoustic properties are preserved.
