Yes — EVs still need annual servicing. No oil or filter changes, but brake fluid, cabin filter, tyres, suspension, coolant for the battery pack, and software updates all matter. Expect £120–£180 a year vs £250+ for a petrol equivalent.

EV owners are often told "electric cars don't need servicing." That's wrong — they need less, not none. Here's what a proper UK EV service covers.

What's on the service schedule

Brake fluid every 2 years (water absorption is the same on any car), cabin filter annually, tyre rotation, suspension inspection, 12V battery test, battery coolant check every 3–5 years, and software updates.

What you don't need

No oil, oil filter, spark plugs, fuel filter, timing belt, exhaust, clutch or gearbox service. That's where the £100+ a year saving comes from.

Brakes wear differently

Regenerative braking means pads and discs can last 70,000+ miles. But because they're used less, they corrode more — annual brake clean and lube is essential.

Why specialist over main dealer

Independent EV specialists are typically 30–40% cheaper than franchised dealers for the same work, and many are now HV-qualified to the same standard.

Can I skip servicing if my EV is under warranty? — No — most warranties are voided if you can't prove the scheduled service was done. Independent EV specialists are warranty-safe as long as they use approved parts.

How often should an EV service be? — Annual or every 18,000 miles, whichever comes first — same cadence as petrol cars, just less work each time.

More detail on: Do EVs need servicing in the UK?

The short answer above covers the usual case. Below is the extra detail a UK driver normally needs to act on it — how to narrow the fault down, what it should cost, and when it is worth paying a garage rather than carrying on. This is general guidance from a working mechanic, not a substitute for someone putting your own car on a ramp.

How to describe the problem so you get a straight answer

Mechanics diagnose faster when they get facts rather than conclusions. Give the make, model, engine size, fuel type, year and mileage; say exactly when the fault happens (cold start, motorway speed, braking, turning, first five minutes); say what changed just before it started; and list any codes, warning lights or recent work. A three-line description in that shape is worth more than a paragraph of theory.

What to do before you spend money

Run a free MOT history check to see whether the same item has been advisoried before — that history often explains a fault in one line. Check whether an open safety recall covers the component, because that repair is free at a franchised dealer. Then get the fault properly diagnosed rather than replacing parts in order of price.

Safe to keep driving?

Treat anything affecting brakes, steering, tyres, seat belts or visibility as stop-now, no matter how well the car appears to be driving. Overheating and low oil pressure are also stop-now: the damage curve on both is measured in minutes, not miles. Most other faults will let you drive gently to a garage, but if the car is in limp mode, losing fluid, or the fault changes how it steers or stops, get it recovered instead. Recovery is cheaper than a tow plus a new engine.

What Bob would check first

Start with the cheap, common and visible: fluid levels and their condition, tyre pressures and wear pattern, battery voltage and terminal condition, and every connector and vacuum pipe in the area of the fault. A surprising share of electrical gremlins are a corroded earth or a chafed loom, and a surprising share of running faults are an air leak downstream of the sensor doing the complaining. Only after that does anything get unbolted.

When it is worth going to a main dealer

Three situations justify main-dealer money: an open safety recall (free), a live manufacturer warranty or goodwill claim, and coding or programming work that needs manufacturer-level software. Everything else — servicing, brakes, suspension, clutches, cambelts, diagnostics — an experienced independent will do to the same standard for a good deal less, and using an independent does not invalidate your warranty under UK block exemption rules as long as the correct parts and schedule are used.
