Your fitter is right — the camera behind the new glass needs recalibrating, and many mobile fitters leave that to a specialist. That is the bit we do.
Send your reg and tell us the glass has been replaced. We will confirm what your car needs and the total before booking.
The bracket goes with the old glass. The camera isn't bolted to the car — it sits in a bracket bonded to the inside of the windscreen, just ahead of the mirror. When the old screen comes out, the bracket goes with it. A new bracket is bonded to the new glass by hand, and the camera goes back into a position that is nearly where it was. Nearly is the problem.
Millimetres at the mirror, metres at fifty. That camera is judging where a car is a hundred feet up the road. A fraction of a degree of tilt at the bracket is a very large error by the time it matters.
The glass itself is part of the optics. Even an identical-spec windscreen has fractionally different thickness, curvature and tint in the camera's aperture. The camera looks through that glass every second it's working. It has to be re-taught what “straight ahead” looks like through the new one.
It's a fair question and it gets asked constantly — usually by people who found out about it when it appeared as an extra line on a bill they'd already agreed. That's not a technical objection, it's a being-ambushed objection, and it's completely reasonable.
So, straight answers.
If your car has no forward camera, you don't need this. Plenty of cars don't. Call us with the reg and if that's your car, we'll say so and you'll owe us nothing. We'd genuinely rather do that than sell you a job you don't need and get a review for it.
If your car does have one, the camera has moved. Not “might have”. The bracket came off with the glass. Whether the car has thrown a warning about it is a separate question — plenty of them don't, they just quietly run lane assist and emergency braking on data that's slightly wrong.
And you get to choose who does it. Your fitter may offer to arrange it; you're not obliged to accept their price or their timescale. It's a separate job by a separate specialist, and it can be booked separately.
What we won't do is scare you. It's not an MOT item. There's no law that names it. The argument for doing it is that automatic emergency braking is only worth having if it's pointed the right way.
A windscreen replacement normally disturbs one system: the forward-facing camera mounted behind the glass. That is a single calibration. If the same job also disturbed a front radar — after a front-end impact, for example — that is a second, separate procedure. We confirm which applies from your registration before anything is booked.

From the driver's seat, look up at the plastic cover behind the mirror. Is it clipped fully home? Is anything visibly skewed or hanging loose? If the mount looks obviously crooked, that's a fitting problem, not a calibration problem — photograph it and go back to your fitter first.
Adhesive haze and fingerprints from fitting sit exactly where the camera looks. A clean, dry microfibre on the inside of the screen, no solvents, no glass cleaner.
Some systems need an ignition cycle and a few miles on well-marked roads before they settle.
If the warning stays, the systems are greyed out, or your fitter has flagged calibration, that's us.
Reg first, price second, calibration third — nothing is a surprise at any step.
Registration, postcode, and what work was done. Thirty seconds by form, WhatsApp or phone.
We check which ADAS systems your car actually has and which need doing, and give you the total before you commit. One calibration or two — you'll know which before we book.
Home, work, or your garage's yard. Static calibration needs a level, reasonably clear space in front of the car — a normal driveway or a workshop bay is fine. We bring everything.
Static targets and/or a dynamic road drive as your manufacturer specifies, a diagnostic check to confirm the systems are live and fault-free.
It is not an MOT item. There is no ADAS calibration check in the MOT, and a lane-assist or Front Assist warning on your dash will not, on its own, fail the test. Anyone telling you otherwise is selling you something. We'd rather tell you the truth and keep the phone number.
It is not, in itself, illegal. There's no law that says “calibrate after new glass”. What the law does say is that your car must be in a roadworthy condition.
Here's the bit that actually matters. These systems don't switch off when they're out of aim. They keep running, on slightly wrong information. A camera aimed a fraction low reads the lane late. A radar aimed a fraction left measures the wrong car. The system still looks like it's working — the icon is lit, the cruise control engages — and you find out it isn't on the one day you needed it. That's the real argument, and it's the only one we make.
If the windscreen was an insurance claim, the calibration is often part of the same claim. Often, not always, and it depends on your policy and your insurer — we can't promise on their behalf and we won't pretend to. What we'll do is give you the vehicle details, the systems calibrated and the results in writing so you have something to submit.
If your fitter is arranging it, we can bill them directly and keep you out of it entirely. A lot of independent fitters across Glasgow and Edinburgh work exactly this way: they fit the glass, we follow them to the same address, the customer gets one job.
If it's just you, it's £180 +VAT for the camera calibration, card or transfer, and you'll know the total before we book.
Windscreen fitters: we will come to your yard and calibrate on site — see the trade page for account pricing.
£180 +VAT for the front camera calibration, which is what most cars need after a glass replacement and nothing else. If your car needs a second system done as well — usually the front radar, and usually only when there’s been damage beyond the glass — that’s a second calibration at £180 +VAT, so £360 +VAT in total. We tell you which applies from your registration before we book.
Allow around an hour at your address for a single camera calibration, longer if your car’s procedure includes a dynamic road drive or if more than one system needs doing. You can carry on with your day while we work.
There’s no law that says “calibrate after new glass”, and it isn’t an MOT test item. What’s true is that the camera has physically moved and lane assist and automatic emergency braking are reading from it. If your car has one, it should be calibrated. If your car doesn’t have one, you don’t need us — call and we’ll tell you free.
Some do. Many can’t — the equipment is expensive and make-specific, so most mobile fitters flag the job and leave it to a specialist. Either way it’s your choice who does it. If your fitter hasn’t arranged anything, you can book us directly and we’ll come to wherever the car is, including their yard.
Where the windscreen was an insured replacement, it’s often included — but that’s your insurer’s call, not ours, so we won’t promise it. We can tell you exactly what was calibrated, and we can invoice your fitter or insurer directly if they’d prefer to handle it.
No. It isn’t an MOT test item and a lane assist warning won’t fail the test on its own. That’s not the reason to do it.
Either. Home, work, or the fitter’s yard, anywhere from Glasgow and Paisley across to Edinburgh, Livingston and Falkirk. For static calibration we need a level, reasonably clear space in front of the car; the dynamic part is done on the road.
No guesswork, no “we'll see when we get there”. Send your registration and what work was done, and we'll come back with exactly how many calibrations your car needs and what the total is — before you commit to anything.
