Tesla Model 3 vs Tesla Model Y - service & running costs compared
Tesla Model 3 vs Tesla Model Y: same brand, same platform, but very different ownership costs over time. Real 2026 UK service prices and which Tesla is actually cheaper to live with.
These two cars share 75% of their parts. Same battery options, same motors, same interior, same software, same Supercharger network.
So why does the Model Y cost more to keep on the road? It comes down to weight, tyre size, and what the bigger body does to consumables.
If you're choosing between them, here's what you'll actually pay over 3–5 years.

Which is cheaper to service?
Both are EVs so there's no oil change, no spark plugs, no timing belt to worry about. Annual EV health check costs are similar - £125–£195 on a Model 3 vs £135–£210 on a Model Y. Marginally more on the Y because the suspension geometry is more involved and the bigger wheels need more torque-spec checks.
Tesla recommends a brake fluid change every 2 years (£45–£85 either car), cabin filter replacement annually (£35–£60), and 12V auxiliary battery replacement every 4–6 years (£140–£270 fitted). That's basically the entire routine maintenance schedule on both cars.
The real cost difference: tyres and brakes
The Model Y is heavier - by 200kg or so - and sits on bigger tyres. That changes the cost picture meaningfully:
- Tyres: Model 3 standard is 235/45 R18; Model Y is 255/45 R19 on Long Range and 255/40 R20 on Performance. Replacement tyre cost: Model 3 around £150–£200 per corner, Model Y £200–£280. Over 4 sets in 4 years, that's £500–£800 more on the Y.
- Brake life: EVs in general are easy on brakes because regen does most of the slowing. Model Y is harder on brakes than Model 3 because of weight - typically replaces front pads at 60k vs 80k miles. Brake pad replacement is £150–£240 on Model 3, £160–£255 on Model Y.
Common issues to watch for
Both cars have very similar reliability profiles. Known issues across both:
- 12V battery failure: common around year 4 on early production cars. Costs £140–£270 fitted. Tesla recommends swap before failure if you're approaching that age.
- Drop links / control arms: 50,000–80,000 miles typical. Both cars use similar suspension; replacement is £110–£225 fitted as a pair.
- Build quality variability: early production Fremont-built Model Ys had panel gap issues. Shanghai-built (most UK cars) is significantly better.
The Model 3 has the edge on aerodynamic efficiency - typically gets 250–270 miles real-world from Long Range versus 230–250 on Model Y Long Range. That's £100–£150/year in electricity over 10,000 miles.
Insurance and depreciation
Insurance groups: Model 3 sits 48–50, Model Y at 48–50 - both in the high-premium bracket due to repair cost (Tesla approved bodyshops are scarce and pricey). Depreciation: both depreciate similarly, around 35–40% over the first 3 years.
Verdict - which costs less to own?
The Model 3 is cheaper to own by roughly £300–£500 a year over a 4-year window - driven by tyres (~��200/year more on the Y), electricity (~£100/year), and slightly more brake wear. That's not enough to pick the 3 over the Y if you actually need the extra space, but it's enough to matter if you don't.
If you'd be happy with a saloon, the Model 3 is the better value EV. If you need the boot height and the higher seating position, the Y is worth the £300–£500/year premium. Both will outlast most petrol and diesel cars in maintenance friendliness.
FAQs: Tesla Model 3 vs Tesla Model Y
Is the Model 3 cheaper to run than the Model Y?
Yes - by roughly £300–£500 a year over 4 years. Most of the gap is tyres (Y has bigger, more expensive tyres) and electricity (Y is less efficient by 20–30 miles per charge). Service costs are nearly identical.
How much is a Tesla service in the UK?
Tesla doesn't do annual services like a combustion car. The annual EV health check at an independent EV specialist runs £125–£195 for a Model 3, £135–£210 for a Model Y. That includes brake check, cabin filter, brake fluid every 2 years, and 12V battery check.
Do Tesla brakes last longer than petrol car brakes?
Yes - much longer. Regenerative braking does most of the slowing, so pads typically last 60,000–100,000 miles. The Model 3 lasts longer than the Model Y on brakes because it's lighter.
Are Teslas expensive to insure?
Yes - both Model 3 and Y sit in insurance groups 48–50, which is high. The reason isn't accident frequency, it's repair cost. Tesla approved bodyshops are limited in the UK and parts are not cheap.
Should I buy a Model 3 or a Model Y?
If you need a higher seating position, taller boot, or are 6 ft+ - Model Y. Otherwise the Model 3 is the better value: similar performance, more efficient, cheaper to run by £300–£500/year. The Y exists because the market wants SUV shapes, not because it's a better car.
