Running a car in the UK isn’t cheap. According to NimbleFins, the average annual cost in 2025 is over £3,350. But with a few smart strategies, you could reduce your motoring expenses—without compromising safety or performance.
Whether you’re stationed in the UK or preparing for deployment, here are some practical tips to help you save money on your vehicle.
1. Save on Servicing
Regular servicing keeps your car running smoothly and helps avoid costly repairs down the line. But you don’t have to pay over the odds:
- Shop around for competitive servicing quotes.
- Stick to the manufacturer’s service schedule to maintain performance and resale value.
- Keep a full service history—this can boost your car’s value when it’s time to sell.
2. Look After Your Tyres
Tyres are vital for safety and fuel efficiency. Here’s how to extend their life:
- Check tyre pressure regularly—incorrect pressure increases wear and fuel use.
- Inspect tread depth and remove debris like stones.
- Get your wheels aligned—misalignment can double tyre wear.
Remember: UK law requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre. Many experts recommend replacing tyres at 3mm for better grip and safety.
3. Lighten the Load
Carrying unnecessary weight—like kit bags, tools, or sports gear—can increase fuel consumption. Clear out your boot and remove roof racks or boxes when not in use to improve fuel economy.
4. Drive Smarter, Save Fuel
Your driving habits have a big impact on fuel efficiency. Try these techniques:
- Accelerate and brake gently.
- Maintain a steady speed—most cars are most efficient between 30–50 mph.
- Avoid idling—use start-stop tech if your car has it.
- Use air con and electrics sparingly—they increase fuel use.
- Change gear early but avoid straining the engine.

5. Choose a Car with Lower Emissions
If you’re in the market for a new vehicle, consider one with low CO₂ emissions:
- Lower emissions = lower Vehicle Excise Duty (car tax).
- From 1 April 2025, even zero-emission vehicles are subject to tax, but they may still be cheaper to run overall.
- Use the VCA tax calculator to estimate your costs.
Cars over £40,000 attract an additional annual charge of £425, unless they’re zero-emission and registered before April 2025.
6. Prepare for Winter Driving
Cold weather can be tough on vehicles. Get ahead of the season with these checks:
- Lights – Clean and check all bulbs.
- Screenwash – Use a winter-grade mix to prevent freezing.
- Battery – Cold weather drains batteries faster—test or replace if needed.
- De-icer and scraper – Keep them handy for frosty mornings.
- Winter tyres – Optional in the UK, but useful if you’re driving in snow or abroad.
