Reviews below are hand-picked from recent UK customers. Across the whole of UK Car Glass, 4.82/5 from 1,456 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.

An aerial laminated into the windscreen or rear window restores radio, DAB or TV reception without a roof-mounted mast.
An antenna is a conductive print laminated into the glass during manufacture, typically used for radio, DAB (digital audio broadcasting) or television reception. It replaces the traditional roof-mounted aerial mast found on older vehicles. The antenna is integrated into the glass interlayer and connected to the vehicle's receiver unit via a connector embedded in the glass edge. This design offers a cleaner aesthetic, reduces wind noise, and eliminates the vulnerability of a protruding mast to damage or theft.
Check your vehicle's roof — if there is no visible aerial mast, your car likely has a laminated antenna. You can also ask your dealer or service centre whether your windscreen or rear window carries an antenna print. The connector may be visible on the glass edge or inside the door frame trim.
When replacing glass with a laminated antenna, the replacement must carry the matching antenna print and connector to restore reception immediately on fitting. Aftermarket or original-equipment glass with the correct antenna specification is essential; a plain replacement will leave you without radio or DAB signal. Our fitters verify the antenna specification during booking and source the correct variant before the appointment.
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.
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.
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.
Solar control glass absorbs infrared rays to reduce heat and improve cabin comfort.
Solar control is a coating applied to the windscreen that absorbs the sun's infrared radiation rather than allowing it to pass through into the cabin. This reduces solar heat gain, helping to keep the interior cooler and more comfortable, particularly in warm weather or direct sunlight. The coating is transparent to visible light, so it doesn't darken the windscreen or affect visibility. It's a passive thermal management feature that works continuously whenever the sun is shining on the glass.
Check your vehicle's specification sheet or contact your dealership service centre to confirm whether solar control glass is fitted. Some manufacturers list it as 'solar control windscreen', 'heat-reflective glass', or 'thermal management glass'. It's a factory-fitted feature and won't be visibly obvious from outside the car — the coating is integral to the glass itself.
Solar control glass is a factory-fitted specification. When replacing the windscreen, a solar control variant must be sourced to match the original. This is a standard glass type with no special fitting implications or calibration requirements. Cure and drive-away times follow normal windscreen bonding procedures. Confirm with your fitter that the replacement glass includes solar control to maintain the original thermal performance.
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.
A brake light integrated into the rear window glass itself, requiring a matching replacement to reconnect the original lighting circuit.
A brake light integrated into the rear window glass is a lighting element built directly into the glass panel during manufacturing. Rather than using a separate lamp cluster mounted to the vehicle body, the light circuit is routed through conductive elements — typically a silkscreen pattern, wire network, or bracket assembly — embedded in or bonded to the glass itself. When you brake, this integrated light illuminates to warn following traffic. It combines functionality with design integration, reducing the number of separate components on the rear of the vehicle.
Check your vehicle's rear window for a visible pattern of fine lines or wires running across the glass, usually near the top edge or spanning the upper portion. Look at your vehicle's manual or contact your dealer's service centre — they can confirm whether your rear window carries an integrated brake light. If you see a separate brake-light cluster mounted to the bodywork instead, your vehicle does not have this feature.
The replacement rear window must carry the identical integrated brake-light pattern so the original lighting circuit reconnects without modification. The conductive elements — whether silkscreen, wiring, or bracket fittings — must align precisely with the vehicle's electrical connections. Using a standard rear window without this pattern would disable the brake light. We source the correct OE-specification glass to ensure a seamless fit and restore full functionality.
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.
