Essential Items to Keep in Your Car
Every UK driver should carry these items from November to March:
- Ice scraper & de-icer spray — never pour hot water on a frozen windscreen
- Torch with fresh batteries — breakdowns happen in the dark
- Screenwash concentrate — ensure it’s rated to at least -10°C
- Spare bulbs — many cars still use easily-replaceable halogen bulbs
- Jump leads or lithium jump starter — the number one winter breakdown cause
- Blanket & high-vis vest — in case of extended roadside waits
Critical Winter Checks
| Consumable | Winter Risk | Action |
|---|---|---|
| Battery | Cold reduces capacity by up to 50% | Check your battery spec |
| Wiper Blades | Ice and frost damage rubber | Find winter wipers |
| Headlight Bulbs | Short days = total reliance on lights | Find bulbs |
| Engine Oil | Cold oil is thicker — correct grade critical | Check your oil spec |
| Cabin Filter | Demisting relies on airflow | Find filter |
| Spark Plugs | Worn plugs make cold starts harder | Find plugs |
Getting Started on Cold Mornings
If your car struggles to start on cold mornings, the most likely causes are:
- Weak battery — the number one cause. If your battery is over 4 years old, replace it proactively.
- Worn spark plugs — old plugs need more energy to fire in cold conditions.
- Wrong oil viscosity — if someone put 10W-40 in a car that needs 5W-30, cold starts will suffer.
- Dirty cabin filter — won’t cause starting issues but will make demisting slow.
Frequently Asked Questions
What’s the most common winter breakdown cause?
Flat or weak batteries cause more than 30% of all winter breakdown callouts in the UK. If your battery is over 4 years old, consider replacing it before winter starts.
Do I need different wiper blades for winter?
Standard quality wiper blades work fine in UK winters. Some premium brands like Bosch offer winter-specific blades with rubber boots that prevent ice build-up on the frame.
Should I change my engine oil before winter?
If your oil change is due within the next 3 months, do it before winter. Fresh oil flows better in cold temperatures and provides better engine protection during cold starts.
How do I stop my windscreen freezing inside?
A clogged cabin filter reduces airflow and makes demisting slower, which can lead to interior condensation that freezes overnight. A fresh cabin filter plus running the air conditioning (even in winter) helps prevent interior ice.

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 →
