Most UK drivers pay somewhere between roughly £100 and £350 for a new car battery supplied and fitted, depending on the battery type your car needs. Every figure on this page is a starting point — the only way to know what you'll actually pay is to get quotes from local garages.
| Vehicle type | Typical range | What affects it |
|---|---|---|
| Small petrol car (standard battery) | £100–£160 | Standard lead-acid battery; fitting is usually a short job. |
| Stop-start car (EFB battery) | £140–£250 | Stop-start systems need an EFB battery — fitting the cheaper type is a false economy. |
| Stop-start / premium (AGM battery) | £180–£350 | AGM batteries cost the most; some cars also need the new battery coding to the car. |
| Larger engines and diesels | £130–£300 | Bigger engines need higher-capacity batteries. |
Four things set the price: the battery type (standard, EFB or AGM), its size and power rating, the brand, and how long the garage takes to fit and code it.
A car battery typically lasts around three to five years, though short journeys, cold weather and long periods parked up can shorten that noticeably. If your battery is in that age bracket and the car is slow to start on cold mornings, it is worth getting quotes before it strands you.
A rapid clicking noise when you turn the key usually means the battery hasn't enough charge to turn the starter motor. A flat or dying battery is the most common cause.
It is not the only possible cause: corroded terminals, a failing alternator or a tired starter motor can produce similar symptoms. A garage can test the battery and charging system in minutes and tell you which it is, which is cheaper than replacing parts on guesswork.
Comparing quotes from several local garages is the only reliable way to see the real local price, because battery prices vary between garages even for the same car. One request goes to vetted garages near you, you compare their prices and book the one you like — free, with no booking fees, and your contact details stay private until you book.

On many older cars, yes, if you're confident and careful. On stop-start and newer cars the battery often needs registering to the car's systems, so garage fitting is the safer choice.
Many will test it cheaply or free when quoting for a replacement. Ask when you compare quotes — it costs nothing to ask.
Usually, and warranty length varies by brand and battery type. Check what's included when you compare quotes rather than assuming.
The MOT doesn't test battery health itself, but a battery that's insecure or leaking can fail. If the car won't start, it can't be tested at all.
Usually under an hour, and often much less. Cars that need battery coding take a little longer.
