Introduction
As the colder months approach, UK drivers know all too well the challenges winter can bring: icy roads, freezing temperatures, heavy rain, and limited visibility. Whether you’re heading to work, doing the school run, or heading out on longer commutes, making sure your car is ready for winter isn’t just a good idea—it’s essential for your safety and peace of mind.
In this guide, we’ll walk you through the key steps to get your car winter-ready for 2025, from essential maintenance checks to simple upgrades that can make a big difference in harsh conditions. We’ll also offer some helpful insight into choosing a vehicle that’s better suited for winter driving—along with how you can finance the perfect winter car through ChooseMyCar, should you decide that a new or used vehicle is the right move.
So, grab a cup of something warm and let’s ensure you’re fully prepared for whatever the British winter throws at you this season.
Why Winter Tires are Essential in the UK
When temperatures consistently drop below 7°C, the rubber in standard tyres begins to harden, significantly reducing grip on British roads. Winter tyres represent one of the most important investments you can make for safe winter driving, yet they remain surprisingly underutilised across the UK.
Unlike all-season options, dedicated winter tyres feature:
- A specialised rubber compound that remains flexible even in freezing temperatures
- Deeper tread patterns (typically 8-9mm compared to 7-8mm on summer tyres)
- Distinctive sipe patterns – small cuts in the tread blocks that bite into snow and ice
- Wider grooves that efficiently channel away slush and standing water
The performance difference is dramatic: winter tyres can even reduce braking distances by up to 11 metres on icy roads compared to standard tyres. That’s often the difference between stopping safely and a collision.
For British drivers, the ideal time to switch to winter tyres is around mid-October to early November, before the first sustained cold spell. We suggest storing your summer tyres in a cool, dry place away from direct sunlight and chemical exposure to maintain their condition.
While the initial investment might seem significant (typically £300-£500 for a full set), consider it essential safety equipment rather than an optional extra. If you live in rural areas that suffer with extreme weather, and you’re worried about tyres, you may even want to consider switching to a reliable SUV that will have no problem dealing with the elements.
Check Your Car Battery
Cold weather can take a toll on your car’s battery. It’s essential to have your battery tested before the temperatures drop significantly. A weak battery can fail to start your car on a cold morning, leaving you stranded. Replacing an old or weak battery before winter is a simple preventive measure that can save you a lot of trouble.
Battery failure remains the number one cause of winter breakdowns in the UK, with the RAC reporting that calls for flat batteries increase by 43% during cold snaps. Cold weather significantly reduces battery capacity while simultaneously increasing the power needed to start your engine.
Signs your battery might struggle through winter include:
- Slow engine cranking when starting
- Dimming headlights when idling
- Dashboard warning lights
- A battery that’s more than 3-5 years old
Most garages and auto parts retailers offer free battery testing services that measure both voltage and cold cranking amps (CCA), the latter being particularly important for winter performance. If your battery shows signs of weakness, replacing it proactively could save you from being stranded on a freezing morning.
Check Antifreeze & Coolant
Engine damage from freezing is entirely preventable yet it remains a common and expensive winter car problem. The antifreeze/coolant mixture in your engine doesn’t just prevent freezing, it also raises the boiling point of water, lubricates the water pump, and contains additives that prevent corrosion.
For UK winter conditions in 2025, ensure:
• Your coolant provides protection to at least -25°C (most of the UK rarely sees temperatures below -15°C)
• The concentration is correct – typically a 50/50 mix of antifreeze and distilled water
• The coolant is fresh – antifreeze effectiveness deteriorates over time as additives deplete
Testing your antifreeze concentration is simple and inexpensive with an antifreeze hydrometer available from any motor factors. The colour of your coolant can also indicate its condition- most modern coolants are either green/blue (IAT type) or orange/red (OAT type). Significant discolouration or particles floating in the fluid indicate it needs changing.
Should you change Windshield Washer Fluid in the Winter?
The simple answer is yes. Standard summer windscreen washer fluid can freeze at temperatures as high as -5°C, potentially damaging your washer reservoir and leaving you unable to clear road salt and grime from your windscreen- a serious safety hazard on winter roads.
For winter driving in the UK, use a high-quality washer fluid that:
- Provides freeze protection to at least -15°C (or -20°C for northern regions)
- Contains effective detergents to cut through road salt and grime
- Includes water repellent properties to improve visibility during heavy rain
- Features anti-smear compounds to prevent glare when driving at night
Be careful to also avoid using household alternatives like washing-up liquid, which can damage paintwork and rubber seals while creating dangerous smears that amplify headlight glare from oncoming traffic.
Be sure to also keep your reservoir topped up throughout winter, as consumption increases significantly with frequent use.
Check the Lights
With daylight hours significantly reduced during British winters, your vehicle’s lighting system becomes critically important for both seeing and being seen. The Highway Code requires all lights to be in working order, but beyond legality, proper lighting is essential for safety when visibility is compromised by fog, rain, or snow.
Add these lighting tests to your winter driving checklist:
- Test all exterior lights including headlights (both main and dipped beam), fog lights, indicators, brake lights, and reverse lights
- Check for yellowed or cloudy headlight lenses that reduce light output – professional restoration or replacement may be necessary
- Ensure headlights are properly aligned to maximise visibility without dazzling oncoming drivers
- Verify that all interior lights function correctly, including dashboard illumination
- Consider upgrading to higher performance bulbs specifically designed for winter conditions
Prepare an Emergency Kit
Being prepared for winter emergencies isn’t about being pessimistic- it’s about practical readiness for the realities of British winter conditions. The Met Office reports that even in our relatively temperate climate, over 200 people are stranded in their vehicles during severe weather events each year.
Your comprehensive winter emergency kit should be tailored to your typical driving routes, and include the following as advised by The Met Office:
- Visibility and safety items: High-visibility vest, warning triangle, torch with spare batteries, and chemical light sticks that work regardless of temperature
- Warmth essentials: Thermal blanket (the foil type takes minimal space), warm hat, waterproof gloves, spare socks, and an emergency foil shelter for extreme conditions
- Communication tools: Fully-charged power bank (at least 10,000mAh capacity), charging cables, and a whistle for attracting attention
- Food & Drink: Energy bars, chocolate, bottled water (replace regularly), and a thermos of hot drink for immediate journeys
- Vehicle recovery: Compact folding shovel, tow rope rated for your vehicle’s weight, jump leads, and traction aids (cat litter or dedicated traction mats)
- Medical supplies: Comprehensive first aid kit including painkillers, any personal medications, and a thermal emergency blanket
For families, include additional supplies appropriate for children, such as extra snacks, spare clothes, and perhaps a small activity to reduce anxiety during delays. If you regularly travel with pets, include supplies for them as well.
Store your emergency kit in a waterproof container secured in your boot where it won’t become a projectile in an accident but remains easily accessible if needed. Review and refresh supplies monthly during winter, particularly food items and batteries.
Inspect & Maintain Brakes
Your car’s brakes are one of the most important safety features, especially in winter when roads are wet, icy, or covered in grit. Reduced traction means stopping distances can increase significantly, so your brakes need to be in top condition.
Book a brake inspection with a qualified mechanic before the cold weather sets in. They’ll check the condition of your brake pads, discs, and fluid. If there’s any wear or reduced performance, get them replaced promptly.
Well-maintained brakes, combined with winter tyres, give you the best possible control in slippery conditions. Although the cost of brake repairs can vary depending on your car, it’s never worth taking the gamble, especially during winter.
Use Winter-Grade Oil and Replace Filters
In cold conditions, your engine oil thickens, making it harder for the engine to turn over and function efficiently. Switching to a winter-grade oil—typically one with a lower viscosity rating—makes cold starts easier and protects your engine during frosty mornings.
Also be sure to replace:
- The oil filter, which ensures clean oil circulates through the engine
- The air filter, to maintain proper airflow and fuel efficiency
Check your vehicle handbook for the recommended oil type and service intervals to keep your engine running smoothly all winter.
Maintain Correct Tyre Pressure in Cold Weather
Proper tire pressure is essential for safe winter driving. As temperatures fall, tyre pressure can drop: often by 1 to 2 PSI for every 10°C decrease in temperature. Under-inflated tyres reduce grip, worsen fuel efficiency, and affect braking distance, all of which are even more critical in winter conditions.
To stay safe:
- Check your tyre pressures weekly during winter
- Inflate tyres to the recommended level (found in your car manual or driver’s side door frame)
- Don’t forget to check the spare tyre, if your car has one
Protect Your Car’s Paintwork from Salt & Grit
Winter brings a higher risk of paint damage and corrosion due to road salt, grit, and moisture. These elements can cause rust, especially around wheel arches, underbody panels, and exposed metal.
To protect your car’s exterior:
- Apply a high-quality wax or paint sealant before winter begins
- Wash your car regularly, especially after driving on salted roads
- Don’t forget to clean the undercarriage, where salt often collects
This simple maintenance step helps preserve your car’s appearance and resale value.
Check Weather Forecasts & Plan Ahead
Finally, UK winter weather can be unpredictable, with sudden changes that affect road conditions. Staying informed helps you drive more safely and avoid unnecessary risks.
Before you travel:
- Check local weather forecasts and road condition updates
- Avoid non-essential journeys during snow, heavy ice, or severe weather warnings
- Allow extra time for travel and drive cautiously, particularly on untreated roads
Being aware and prepared can help you avoid breakdowns, delays, or accidents during the winter months.
