Rear-window pricing varies based on the features integrated into your specific variant — antenna type, brake-light integration, and alarm-wire circuits all add complexity to the part specification. Later-generation models with more integrated electronics typically carry a higher baseline cost than earlier variants.

Showing 1 review from verified Mercedes GLA owners. Across the whole of UK Car Glass, 4.81/5 from 1,490 Trustpilot reviews.
Booking your rear-window replacement through UK Car Glass is straightforward and takes just a few minutes.
Complete a quick online quote using our guided tool — takes under a minute to confirm your GLA variant and its rear-window features.
Our parts-check team verify the exact specification of glass you need — antenna print, brake-light silkscreen, and any alarm-wire circuits are matched to your factory setup.
We match you with a specialist fitter in your area who has the right equipment and experience for your vehicle.
Your fitter arrives at your preferred location (mobile at your address is the default, or a workshop if you prefer) and removes the shattered rear glass carefully, clearing accessible shards as part of the job.
The new glass is bonded into place with automotive-grade adhesive and tested for seal integrity before the fitter leaves.
We recommend a professional interior valet afterwards, as small glass shards can lodge in places fitters can't always reach on the day.
Your replacement is covered by a two-year warranty on workmanship and glass quality, with support from UKCG throughout.
Most GLA rear-window replacements are carried out mobile at your address — the default option. Since the rear window does not carry an ADAS camera, calibration is not a factor.
A workshop visit may be preferred if you want the interior professionally cleaned immediately after the job, or in poor weather. The choice is yours at booking; mobile fitting is typically faster and more convenient.

Heated rear windscreen with integrated wires clears mist and ice when you switch on the demister.
A heated rear windscreen contains fine heating wires embedded within the glass. When you activate the rear demister, an electrical current passes through these wires, warming the glass and melting ice or condensation. This feature is particularly useful in cold or damp weather, improving rear visibility quickly. The heating grid is integral to the glass and connected to your vehicle's electrical circuit via connectors at the base of the windscreen.
Look at the rear windscreen from inside the vehicle — you will see a fine grid of horizontal lines across the glass, typically bronze or copper in colour. On the dashboard or steering wheel stalk, there will be a dedicated rear-demist button, usually marked with a windscreen symbol and heating lines. If in doubt, ask your vehicle's service centre or consult your handbook.
Replacement rear windscreens with heated grids are widely available as original-equipment aftermarket or dealership parts. The new glass must include the factory heating grid and electrical connectors intact. The technician will reconnect the heating circuit to your vehicle's rear-demist switch. Heated rear windscreens are bonded glass, so adhesive cure time applies; drive-away time will be confirmed by the fitter on the day.
On the Mercedes GLA: fitted on 6 of the 8 rear window variants we list (75%); model years 2012–2026.
A TV-reception aerial printed into the rear window, typically for in-car entertainment systems.
A TV antenna is an aerial pattern laminated into the rear windscreen or rear side window to receive broadcast television signals. It's a separate system from the vehicle's radio or mobile antenna and is typically found in vehicles equipped with rear-seat entertainment systems. The antenna is printed directly onto or into the glass during manufacture, so when the glass is replaced, the antenna pattern must be reproduced on the replacement to maintain reception quality.
Check your vehicle's specification sheet or handbook for rear-seat entertainment or TV tuner capability. If your car has a rear-seat entertainment system with a TV tuner, the rear window will have a TV antenna. You can also ask your dealer or service centre to confirm whether your vehicle has this feature.
When the rear window is replaced, the replacement glass must include the matching TV antenna print to preserve reception. OEM (original equipment manufacturer) glass is typically required to ensure the antenna pattern is identical. The antenna is passive and requires no calibration or specialist procedures after fitting. Cure time for bonded rear glass is required; the fitter will confirm the drive-away time on the day.

Dark grey tint on rear windows provides privacy and reduces interior heat and glare.
Dark grey tint, formally known as privacy glass, is a factory-applied tint created through a deep-dipping process during glass manufacture. The pigment is infused into the inner surface of the glass, darkening the rear windows (and sometimes rear doors) significantly more than the front. This reduces heat transmission, minimises glare, and obscures the interior from outside view. It's standard on the rear half of many modern vehicles.
Compare the rear side windows and rear window (backlight) to the front side windows — the rear glass will be noticeably darker. Check your vehicle documents or ask your dealership service centre if you're unsure whether your car left the factory with privacy glass.
Dark grey tinted glass must be sourced from the Original Equipment Equivalent (OEE) or dealership to ensure colour and transmission match your vehicle's existing rear glass. The tint is integral to the glass itself, not a surface coating, so aftermarket non-tinted glass will look visibly mismatched. Replacement does not require any calibration and follows standard bonded-glass cure times for rear windows.
On the Mercedes GLA: fitted on 3 of the 8 rear window variants we list (38%); model years 2013–2026.
A high-level brake light integrated into the rear window via silkscreen and wire network. The replacement glass must carry the same integrated pattern so the original lighting circuit reconnects cleanly.
Fitted to many GLA variants from the mid-2010s onwards; confirmed as part of the specification during your quote.

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

The glass absorbs the sun's infrared rays, reducing cabin heat gain and improving air-conditioning efficiency.
Available as an option on mid-spec and premium GLA variants; confirmed in the parts-check phase.
The Mercedes-Benz GLA has been in continuous production since 2014, evolving through two major generations. The rear window on GLA models typically features toughened glass with integrated features such as an antenna for radio and keyless entry, and on many variants, a brake light integrated into the glass itself.
From the early 2020s onwards, higher-specification GLA models began incorporating Driver Assistance Packages with front-mounted cameras for lane-keeping and collision warning. Rear-window replacement is straightforward and does not require ADAS calibration, as cameras are mounted to the windscreen.
