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.
