How much does car maintenance cost per year?

DIY: Â£80-150. At a garage: Â£250-500+. The biggest variable is whether you need a new battery (every 4-6 years) or spark plugs.

Can I do my own car maintenance without voiding the warranty?

Yes â EU law protects your right to service your own car. You must use parts that meet the manufacturer's specification and keep records. The key is using the correct oil spec, correct bulbs, etc.

How we check fitment for this guide

We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
