Heavy snow & ice
Driving the biggest cause of harm; cold-weather plan triggers for the vulnerable.
Context
UK heavy snow events are most common in Scotland, the Pennines, and Wales, but southern UK gets disruptive events 2–4 winters out of 10. The Met Office cold weather plan triggers cascade through Level 1 (winter readiness) → 2 (alert) → 3 (severe weather action) → 4 (major incident) — Level 3+ means the vulnerable should not be alone.
When this matters
Met Office snow / ice warning, especially yellow → amber. Cold-Health Alert (CHA) at amber or red.
Before
- Check on elderly neighbours — Level 3 cold weather alerts are a trigger to call in.
- Stock food and medication for 3–5 days. Heating fuel if you use oil or solid fuel.
- Snow shovels, grit, ice melt for paths.
- Winter tyres or chains if you live somewhere snow-prone.
- Insulate water pipes — the freeze-thaw burst is the most expensive UK winter property damage event.
During
- Don't drive unless essential. Check Highways England before you set off.
- If you must drive: full tank of fuel, charged phone, blanket, water, snacks, jump leads, snow shovel. Travel with someone if at all possible.
- Pavement clearing: clearing the path outside your home does NOT make you liable if someone slips — the UK government has confirmed this. Use grit or salt; just shovelling exposes ice.
- Frozen pipes: thaw slowly with hot water bottles or a hairdryer on low heat. Never use a naked flame.
- Don't leave the car running for warmth in a closed garage or with snow blocking the exhaust — carbon monoxide kills.
After
- Burst pipes: turn off the water at the stopcock immediately, then thaw. Insurance covers most domestic burst pipes.
- Roof loading: if your roof has more than 30 cm of wet snow, it's worth getting it cleared by a professional — old UK pitched roofs are designed for moderate loads.
- Pothole season — drive cautiously and report potholes via fixmystreet.com or your council.
