Replacing one TPMS sensor in the UK typically costs about £60 to £150 all in, covering the sensor, fitting, programming and rebalancing. Aftermarket sensors start around £50 and dealer parts run £110 to £180. A full set of four is roughly £220 to £400. Call 07955 533000 for your figure.
TPMS stands for tyre pressure monitoring system. If that light has just appeared and somebody has already quoted you a number that made you wince, read on. There is a fair chance you need less than you have been told.
TPMS Replacement Costs At A Glance
These are the 2026 UK market ranges. Our own work sits inside them, and your figure is confirmed on the phone before we set off.
| What you need | Typical UK price | What it covers |
|---|---|---|
| TPMS valve service kit, per wheel | £5.99 to £25 | Valve hardware only, no electronics |
| Aftermarket sensor, part only | £50 to £90 | The sensor itself |
| OEM or dealer sensor, part only | £110 to £180 | Original equipment manufacturer branded sensor |
| One sensor supplied and fitted, all in | £60 to £150 | Sensor, fitting, programming, rebalance |
| All four sensors replaced | £220 to £400 | Full set, labour shared across the visit |
| Sensor swapped during a tyre change | Lower than a standalone visit | Bead already broken, labour shared |
| TPMS diagnostic scan | Often free with work, £15 to £30 alone | Reads which sensor has failed |
| Light reset or relearn only | Cheapest option by a long way | No parts needed |
Notice the spread. £5.99 at one end, £180 at the other, for things that sound identical to most drivers. That confusion is not your fault and the next section clears it up.
We do not print a single fixed figure of our own against each row, because a relearn on a driveway in Bearsden and two corroded sensors on the A9 are not the same job. Give us the make, model, year and registration and you get a real number in a couple of minutes.
What Is A TPMS Sensor, In Plain English?
A TPMS sensor is a small battery-powered unit that lives inside your wheel, usually built into the valve. It measures the air pressure in that tyre and radios the reading to the car’s ECU, the electronic control unit that runs the dashboard. When the pressure drops, typically by around 6 to 7 psi, the light comes on.
Each sensor has its own sensor ID, a unique code the car learns so it knows which wheel is talking to it.
The battery is sealed inside the unit and cannot be changed on its own. That is the single fact that explains the price. When the battery dies, the whole sensor is replaced, which means the tyre has to come off the rim to get at it.
Direct Versus Indirect TPMS, And Why It Changes Your Bill
Not every car has sensors in the wheels, and this is worth two minutes of your time before you spend anything.
Direct TPMS has a physical sensor inside each wheel. That is what this article is about.
Indirect TPMS has no sensors at all. It works out pressure from the ABS wheel speed sensors, because an underinflated tyre has a slightly smaller rolling radius and turns marginally faster. There is nothing inside the wheel to replace, so a “sensor replacement” quote on an indirect car is wrong.
How to tell which you have: if your dashboard displays individual pressures for each tyre, you almost certainly have direct TPMS. If the light is just a warning symbol with no numbers, it may well be indirect, and the fix is usually a reset after inflating the tyres. The RAC’s TPMS guide explains the split in more detail.
If you have indirect TPMS, you do not need us and you do not need a sensor. Set your pressures correctly and reset the system.
TPMS Valve Service Versus Full Sensor Replacement
This is where most of the confusion in the market comes from, and almost nobody explains it.
| TPMS valve service kit | Full sensor replacement | |
|---|---|---|
| What it is | The perishable valve hardware | The electronics inside the wheel |
| What it includes | Rubber grommet or snap-in stem, locating washer, locking nut, valve core, cap | A complete new sensor, plus a fresh service kit |
| Typical price | £5.99 to £25 per wheel | £60 to £150 all in |
| When you need it | Every time the tyre comes off the rim | When the battery is flat or the unit is damaged |
| Does it fix a warning light | Only if the fault was a leaking valve | Yes, when the sensor has failed |
A valve service kit is the rubber and metal bits that seal the sensor to the rim. They perish. Halfords publish their valve service at £5.99 per wheel and list exactly those components, which is a genuinely useful reference.
A sensor replacement is the electronics. Different part, different price, entirely different job.
Where drivers get caught out is seeing £5.99 advertised and assuming that is what a dead sensor costs. It is not, and any fitter who lets you believe it is setting you up for an argument later.
Kwik Fit’s own advice is that TPMS sensors should be serviced whenever a tyre bead is broken, and that is sound. A fresh service kit each time is the cheapest insurance there is against the corrosion problem in the next section.
Why Do TPMS Sensors Fail?
Four reasons, and only two of them cost you real money.
Flat Sealed Battery
Sensor batteries last roughly five to ten years, or around 100,000 miles, and they are sealed inside the unit. The RAC puts the upper end at about ten years, Kwik Fit at five to seven.
Practical upshot: a car around eight to ten years old will usually start losing sensors one at a time. That is normal, not a fault with the car, and not a sign that somebody has done a bad job.
Corrosion, Road Salt And Scottish Winters
This is the one the national guides underplay, and in Scotland it is arguably the bigger cause.
Most TPMS sensors use an aluminium valve stem with a steel locking nut on the outside. Aluminium and steel in contact, plus salt water, is a corrosion cell. Every Central Belt winter puts salt on the M8, the M74 and the M77, and it works its way into that joint.
What happens next is that the stem seizes solid. When a tyre comes off a few years later, the stem can shear clean off as the nut is removed. A routine tyre change becomes a sensor replacement, and neither the fitter nor the customer wanted that.
Nine times out of ten on a Scottish car over seven years old, it is not the battery that kills the sensor, it is the salt.
An honest fitter stops, shows you the broken stem, and quotes the sensor before doing anything else. That is exactly how we handle it.
Physical Damage And Kerbing
Pothole strikes, kerbing on tight tenement streets, and careless tyre fitting elsewhere. A sensor cracked by a machine that was rushed will fail months later.
Pairing And Software Faults
Sometimes the sensor is perfectly healthy and simply was never relearned to the car, usually after a wheel swap or a winter tyre changeover. A diagnostic scan finds this in minutes and the fix costs a fraction of a sensor.
Which is why we scan before we sell anything.
Will A Faulty TPMS Fail Your MOT?
Yes. It is a straight fail, and there is no grey area.
TPMS checks joined the MOT in January 2015. The rules tightened in May 2018 and again in June 2019, and a TPMS malfunction is now classified as a major defect, which means the vehicle fails. Cars registered from 1 January 2012 with a TPMS system fitted are tested on it.
Kwik Fit, citing TyreSafe, estimate that as many as 20,000 MOT tests have been failed on a TPMS warning light. That is a lot of retest fees for something that is usually a one hour job.
The practical bit. If your MOT is in the next fortnight and that light is on, deal with it now. A fail plus a retest costs more than the sensor, and you lose the car for a second appointment as well.
You do not need to book the car into a garage for this. A van can come to your house or your work, scan it, fix it and clear the light while you carry on with your day.
MOT coming up? Call or WhatsApp 07955 533000. Send us the make, model, year and registration and we will confirm the right sensor and the price before the van leaves Polmadie. Open 24 hours a day, 7 days a week, including weekends and bank holidays, with an average arrival across Glasgow of 30 to 45 minutes.
What Actually Happens During A Mobile TPMS Replacement
The most common objection we hear is that a van cannot do the electronics. Here is the full job so you can judge for yourself.
- Diagnostic scan to confirm which sensor has failed and read its ID.
- Deflate and break the bead, the seal between the tyre and the rim.
- Remove the tyre from the rim on the van’s tyre machine.
- Remove the old sensor and inspect the rim seat for corrosion.
- Fit the new sensor with a fresh service kit, torqued to spec. Never cranked tight, because overtightening is what cracks stems eighteen months later.
- Refit and inflate the tyre to the manufacturer’s pressure.
- Rebalance the wheel on the on-board balancer, because the assembly has been disturbed.
- Programme and pair the new sensor to the vehicle, then run the relearn.
- Refit the wheel and torque to the manufacturer’s setting.
- Confirm the light is out before we leave.
Around 30 to 45 minutes for a single sensor, done on a driveway or in a car park.
Programming And Pairing Explained
There are two routes and the tool on the van does both.
Cloning. The failed sensor’s ID is copied onto the new unit, so the car never knows anything changed. No relearn needed. This is the neatest option when the old sensor can still be read.
New ID plus relearn. A fresh ID is written to the sensor and then taught to the vehicle. Some manufacturers accept a static relearn done at the kerbside in a couple of minutes. Others need a drive cycle relearn, where the car learns the sensors over a short drive. We tell you which yours needs.
Either way, the OEM-grade programming tool travels on the van alongside the tyre machine and the balancer. All three are needed, which is exactly why a mobile operator without them cannot really offer TPMS.
Do You Need To Replace All Four Sensors?
No. Not usually, and anyone who leads with a set of four before scanning is guessing.
Here is the honest nuance though. If the car is nine years old and one battery has died, the other three are exactly the same age and were fitted on the same day. They will follow, probably within a year or two. Doing all four in one visit saves you three more callouts and three more bead breaks in the future, and the labour is shared across the visit rather than paid four separate times.
A simple decision rule:
- Under six years old: replace the one that failed. The others have years left.
- Six to eight years old: replace the failed one, and ask us to check the battery health of the others while the tool is connected.
- Over eight years old, especially with new tyres going on anyway: seriously consider all four. This is the cheapest moment you will ever get.
A set of four across the market runs roughly £220 to £400. We will not push that on a five year old car, and if you ask for four when you need one, we will tell you so.
Dealer Versus Independent Versus Mobile
| Main dealer | Independent garage | Mobile | |
|---|---|---|---|
| Typical sensor part cost | £110 to £180, OEM | £50 to £90, quality aftermarket | £50 to £90, quality aftermarket |
| Sensor type used | Manufacturer branded | Programmable universal | Programmable universal, OEM on request |
| Time out of your day | Half a day, booked in advance | A couple of hours | None, we come to you |
| Availability | Weekday working hours | Weekday and some Saturdays | 24 hours, 7 days |
| Works if the car is not driveable | No | No | Yes |
One genuinely useful thing worth knowing. Autodoc’s UK cost research found that labour rates in Scotland and northern England run roughly £30 to £60 lower than London and the South East on this job. So a Scottish driver comparing themselves to a London price guide is looking at the wrong number, and in your favour for once.
Honest verdict: a main dealer is the right choice if your car is still under manufacturer warranty or it is a premium German model with a fussy system. For everybody else, a quality aftermarket sensor fitted and programmed properly does the identical job for considerably less.
Are Universal Aftermarket Sensors As Good As OEM?
For most cars, yes. A good programmable universal sensor from a reputable manufacturer covers the vast majority of vehicles on UK roads and, once paired, performs identically to the factory part. The car cannot tell the difference, because the sensor is reporting the same data on the same protocol.
The reasons to insist on OEM are narrower than the dealer will suggest. A vehicle still inside its manufacturer warranty, where a main dealer service history matters. Certain premium German models with tightly controlled systems. And occasionally a very new model where universal coverage has not caught up yet.
Outside of those, paying £180 for a part that does the same job as a £70 one is a choice, not a requirement. We stock quality aftermarket as standard and will source OEM if you want it.
How To Save Money On TPMS Replacement
- Change the sensor at the same time as a tyre. The bead is already broken and the labour is shared. Autodoc call this the single most cost-effective strategy and they are right. If you are having a tyre off anyway, that is the cheapest moment you will ever get to change a sensor.
- Fit a fresh service kit every time a tyre is changed. A few pounds a wheel that stops the stem corroding into a full sensor replacement later.
- Get a diagnostic scan before authorising any parts. A relearn costs a fraction of a sensor and it fixes a surprising number of lights.
- Only do all four when the age case supports it. Under six years old, one is one.
- Do not ignore the light. An MOT fail plus a retest costs more than the sensor, and you lose a second day to it.
Real Jobs: TPMS Work Across Glasgow And Scotland
A driveway in Bearsden, Sunday afternoon. A driver had fitted a set of second hand winter wheels and the TPMS light stayed on no matter what he did with the pressures. He had convinced himself he was looking at four new sensors and several hundred pounds.
The technician scanned all four wheels. Every sensor was healthy and transmitting. They had simply never been relearned to the vehicle after the changeover. The relearn procedure was run at the kerbside and the light went out.
Cost was a diagnostic and a relearn, not four sensors. Always scan before you buy parts.
A driveway in Bishopbriggs, Wednesday evening. MOT in nine days. A 2014 Volkswagen Passat with a TPMS light that had been on since the spring. The owner assumed it was a pressure issue and had been topping the tyres up for months.
The scan found one sensor not reporting at all, flat internal battery, with the other three transmitting healthily. One programmable aftermarket sensor went in, was paired to the car, the wheel was rebalanced and the light cleared before the van left. He passed the MOT.
If the light comes back on twenty minutes after you have set the pressures, it is not the pressures.
A street in Rutherglen, Saturday morning. Two new front tyres going onto an eight year old Ford Kuga. On the nearside, the aluminium valve stem had corroded solid into the locking nut and it sheared as the technician backed it off.
He stopped there. Showed the customer the broken stem, explained that this is what a decade of Scottish road salt does, and quoted the sensor replacement before touching anything else. The customer agreed, the sensor went in with a fresh service kit, and the job carried on.
On a car of that age, budget for the possibility. And expect any honest fitter to show you the part before charging you for it.
Mobile TPMS Replacement Across Glasgow And Scotland
Glasgow And The Central Belt
We work from 100 Jessie St, Polmadie, and cover every postcode from G1 to G84, plus Paisley, East Kilbride, Clydebank, Rutherglen, Bearsden, Bishopbriggs, Hamilton, Motherwell, Wishaw and Kilmarnock.
Salt spreading on the M8, the M74 and the M77 through a Central Belt winter is the reason so much of our TPMS work is corrosion rather than dead batteries. It is not a national pattern, it is a Scottish one.
Edinburgh, Dundee, Aberdeen And Beyond
Coverage extends to Edinburgh, Perth, Stirling, Falkirk, Dundee, Aberdeen and Ayr, plus Carlisle across the border. Distance affects the quote on longer runs, and it is confirmed on the phone before the van leaves rather than discovered afterwards.
Highland And Rural Scotland
On the A9 and the A82, a TPMS light often means a long round trip to find a garage that can actually programme a sensor, not just fit a tyre. A mobile visit removes that problem entirely.
One Friday run near Inverness was exactly that. Two lights, two failed sensors, replaced on site with fresh service kits fitted to all four while the tool was out, and both affected wheels rebalanced. The distance was reflected in the callout and quoted on the phone first. Out there, the mobile option frequently costs less than the fuel and the lost day of hunting for someone with the right kit.
Common Worries About TPMS Costs
“TPMS is just a money-making racket”
The part is the size of your thumb and it costs what a decent tyre costs. I know exactly how that sounds. Here is the reasoning: it is a sealed, battery-powered radio transmitter that has to survive ten years inside a wheel at motorway speed in Scottish weather, and it has been an MOT item since 2015. The price is not the annoying bit. The annoying bit is that the battery cannot be replaced on its own, and that is a design decision nobody asked us about either.
“Can I not just reset the light?”
Sometimes, genuinely. A reset or relearn works when the sensor is healthy and the car has simply lost track of it, which happens after a wheel swap or a seasonal changeover. It will not work when the battery is flat, because there is nothing left to talk to. A scan tells you which situation you are in, and it takes minutes.
“The dealer quoted £150 for one sensor”
That is a normal OEM price, so nobody is ripping you off. It is just not the only option. A quality programmable aftermarket sensor costs roughly £50 to £90 and performs identically once paired, unless your car is still under manufacturer warranty or is a make with a particularly closed system.
“Can a mobile van really programme a sensor?”
Yes, and here is the test to apply to anyone claiming they can. Ask whether they carry a tyre machine, a wheel balancer and a programming tool. You need all three, because the sensor lives inside the tyre and the wheel has to be rebalanced afterwards. Ours carry all three. Plenty of mobile operators carry none.
“Will you push me into replacing all four?”
No. The decision rule is published above and we stick to it. Under six years old, you get the one that failed. On an older car we will tell you honestly that the others are the same age and let you decide, which is not the same as selling you four.
“What if the sensor snaps off during the job?”
On older Scottish cars it happens, and we would rather warn you now than surprise you then. If a corroded stem shears, the technician stops, shows you the broken part and quotes the replacement before doing anything further. Nothing gets added to your bill without a conversation first.
TPMS Sensor Replacement FAQs
How much does it cost to replace one TPMS sensor? Around £60 to £150 all in across the UK, covering the sensor, fitting, programming and rebalancing. The part alone is £50 to £90 aftermarket or £110 to £180 for a dealer OEM unit. Ring 07955 533000 with your make, model and year for your own figure.
How much does it cost to replace all four TPMS sensors? Roughly £220 to £400 for a full set fitted and programmed. It works out cheaper per sensor than four separate visits because the labour is shared, which is why it is worth considering on a car over eight years old.
Will a faulty TPMS sensor fail an MOT? Yes. A TPMS malfunction has been classified as a major defect since the rules tightened, which is an automatic fail. Checks joined the MOT in January 2015 and apply to vehicles registered from 1 January 2012 with TPMS fitted.
Can you drive with the TPMS light on? The car will still drive, but you are running without a working pressure warning and you will fail your next MOT. More importantly, the light might be telling the truth about a genuinely soft tyre. Check your pressures first, and if the light stays on, get it scanned.
How long do TPMS sensors last? Roughly five to ten years, or around 100,000 miles. The battery is sealed inside and its life is the limiting factor. On a car approaching a decade old, expect them to start failing one at a time.
Can you replace just the TPMS sensor battery? Almost never. On the vast majority of sensors the battery is sealed inside a moulded unit and cannot be accessed without destroying it. That is why the whole sensor is replaced rather than just the cell.
What is the difference between a TPMS service kit and a new sensor? A service kit is the perishable valve hardware, the stem or grommet, washer, locking nut, valve core and cap, at roughly £5.99 to £25 per wheel. A sensor is the electronics inside the wheel at £60 to £150 fitted. The kit should be renewed every time the tyre comes off.
Do TPMS sensors need programming to the car? Yes, almost always. Either the failed sensor’s ID is cloned onto the new unit, or a new ID is written and relearned to the vehicle. Some cars accept a static relearn at the kerbside, others need a short drive cycle. A programming tool is essential either way.
Do you have to replace all four sensors at the same time? No. Replace the one that has failed if the car is under six years old. On a car over eight years old, where all four batteries are the same age, doing them together in one visit usually works out cheaper than three more callouts later.
Is it cheaper to replace TPMS sensors when getting new tyres? Yes, noticeably. The tyre is already off the rim and the bead already broken, so you are only paying for the part and the programming rather than a separate job. If you know a sensor is on its way out, time it with your next tyre.
Can a mobile tyre fitter replace a TPMS sensor at my home? Yes, provided the van carries a tyre machine, a wheel balancer and a programming tool. All three are needed. Ours do, so the whole job including the relearn happens on your driveway or in your work car park in about 30 to 45 minutes.
Do you cover TPMS replacement across Scotland? Yes. Every Glasgow postcode from G1 to G84, the wider Central Belt, and out to Edinburgh, Perth, Stirling, Falkirk, Dundee, Aberdeen, Ayr, Inverness and the Highlands. Distance is factored into the quote and stated before we set off.
