Met Office urges households in 18 English regions to prepare an emergency kit — full list

When the weather service warns of heavy rain, it’s easy to push it to the back burner. But timing matters. A yellow weather alert covering 18 regions across England signals that rain could arrive heavily enough to disrupt travel and push some areas toward flooding. If you haven’t already, it’s a smart move to assemble a practical emergency kit and take a few precautions now. Think of it as your home’s safety belt—there to soften the blows when the weather turns rough.

In this guide, we’ll translate that warning into simple steps you can take today. You’ll learn what to put in your emergency kit, how to protect your home and heating system, and what to do if you’re on the road when the rain arrives. Along the way, you’ll find practical tips, checklists, and a few quick reminders about heating care that can save you time and hassle later.

Why this warning matters for homes and households

Yellow alerts aren’t an alarm bell that something terrible will happen, but they are a signal to prepare. When forecast rainfall ranges from 15 to 25 millimetres over broad areas — with some places seeing 30 to 40 millimetres, and even heavier amounts on hills — you can expect wetter roads, puddles that linger, and the chance of localized flooding near rivers, drainage systems, and low-lying streets. It’s not just about the rain; it’s about how that rain interacts with traffic, power supplies, and everyday routines.

From a practical standpoint, heavy downpours can reduce visibility, make driving hazardous, and complicate commutes. For households, that means planning for possible changes in travel plans, delays for deliveries or services, and the potential for short-term outages. Preparing now reduces stress later and helps you stay safe without scrambling at the last minute.

What to put in your emergency kit: a practical checklist

An emergency kit isn’t a bunker; it’s a compact, ready-to-go bundle that covers essentials for a day or two if flooding blocks access or power goes out. Use this checklist to tailor a kit that fits your home and household needs. The goal is simple: have what you need, where you need it, without digging through cupboards when the rain is already pouring outside.

• Water and food: At least 2 litres of water per person per day for drinking, plus a few extra bottles for pets. Stock non-perishable foods that don’t require cooking or refrigeration if power is out for a while.
• Lighting and power: A fully charged power bank, waterproof torches or lanterns, extra batteries, and a portable charger for phones. If you rely on electricity for medical devices, plan for contingencies.
• Communication and information: A battery-powered radio or a charged phone with offline copies of important numbers and local hazard updates.
• Warmth and protection: Warm clothing, blankets, waterproof jackets or ponchos, and sturdy footwear to handle slick surfaces and floodwater.
• First aid and medications: A basic first-aid kit, a seven-day supply of prescription medicines, and any essential medical items for family members or pets.
• Documents and valuables: A small waterproof bag for important documents (IDs, insurance, medical information), a copy of emergency contacts, and precious items you’d regret losing.
• Sanitation and hygiene: Wet wipes, hand sanitiser, toilet paper, and bags for waste or damp items.
• Home safety aids: A small toolkit, duct tape, a waterproof sealant, and spare fuses or a multi-plug surge protector if needed.
• Household essentials: A first-aid flashlight, spare keys, and a list of emergency contacts including local authorities and utility providers.

Tailor this list to your needs. If you have young children, elderly family members, or pets, add items that keep them safe and comfortable. For example, a stash of baby formula or pet food, or a small portable ramp if you have mobility concerns. The idea is to be prepared, not overwhelmed.

Protecting your heating system during heavy rain and potential outages

Your heating system is a lifeline in cold, wet weather. A power outage or flood risk can compromise it, so it pays to think ahead. A few proactive steps can keep boilers and radiators functioning when it matters most.

Inspect and prepare your boiler and controls

Before the rain hits, check that your boiler is serviced and functioning properly. A well-maintained boiler operates more efficiently and is less vulnerable to weather-related hiccups. Don’t wait for a cold snap to realize your heating needs attention.

Consider a professional service for system cleanliness

Over time, sludge and deposits in central heating pipes can reduce efficiency and cause noise, cold spots, or poor hot water output. If you want a smoother, more reliable system, consider services like Powerflush to clear the boiler loop and radiators. It’s a smart step when weather turns nasty and you want reassurance that your heating will perform when you need it most.

Beyond cleaning, a trusted technician can check for leaks, tighten connections, and ensure your hot water supply remains stable. If you’re shopping for reputable heating help, Powerflush is a resource worth considering, alongside your regular maintenance plan.

For ongoing maintenance and reliable service, you might also consider a trusted local provider such as Harrow Heating. Regular servicing and prompt attention to any anomalies can prevent downtime during a storm, keeping your home warm and comfortable even when the weather rages outside.

Home readiness: securing doors, windows, and flood-prone areas

Preparation isn’t glamorous, but it’s incredibly practical. Your goal is to reduce the chance of floodwater entering the home and to minimize the damage if it does. A few proactive steps can make a big difference.

Seal and shield vulnerable entry points

Inspect doors and low-level windows for gaps. Use weather stripping or door sweeps to keep rain from seeping indoors. In flood-prone spots, consider temporary barriers such as sandbags or flood protection columns. The aim is to act like a dam—holding back water before it can do real harm.

Protect electrical outlets and wiring

If you’re in a flood risk area, keep electrical switches and sockets elevated and clear of potential water ingress. Have an emergency plan to switch off the mains if advised by authorities.

Safeguard valuables and utilities

Move valuables and electronics to higher shelves or upper floors where possible. Put essential documents in waterproof containers and ensure you have a plan for moving them quickly if water levels rise.

Safe travel decisions during heavy rain

Rain didn’t come with a calendar. It can arrive abruptly and change traffic conditions in minutes. If you must travel, a few smart habits can keep you safer on the road.

Check real-time warnings before you set out

Rely on live weather updates and traffic feeds. If a route looks compromised by floods, it’s often wiser to delay until conditions improve. It’s better to arrive late than to risk getting stranded in rising water.

Drive with extra caution

Heavy rain can reduce tyre grip, hide potholes, and flood underpasses. Slow down, increase following distance, and turn on headlights to improve visibility. If you encounter flooded roads, turn around—there’s no safe shortcut through water.

Alternative options and planning in advance

Know where you can seek shelter or refuel if a trip takes longer than expected. Having contact numbers for roadside assistance or local garages can save you time and stress if a vehicle issue crops up.

What to do after the warnings ease and water recedes

Once the deluge subsides, the real work often begins: cleanup, drying out, and checking for hidden damage. A measured approach helps you recover faster and protect your belongings for the next storm.

Assess and document damage

Take photos of any damage to walls, flooring, or furnishings for insurance purposes. Start with a quick, safe assessment and then plan longer-term repairs as needed.

Dry and ventilate the home

Open windows and doors to promote air flow. Use fans if available and move damp items to dry areas. The quicker you dry out spaces, the less risk there is of mold and further damage.

Check heating and electrical systems after water exposure

If there’s any chance that water affected electrical systems or the boiler, get a professional to inspect before turning power back on. Safety first. This is another reason to have trusted technicians in your network, like Harrow Heating for heating concerns and Powerflush for potential boiler flushing needs.

Key tips to stay prepared in future warnings

Preparation isn’t a one-off task. It’s a routine—an easy habit you can cultivate to reduce stress when the forecast flips to rain. Here are a few practical, repeatable steps you can apply before every storm season.

• Seasonal checklists: Review your emergency kit every few months and rotate food, water, and batteries as needed.
• Household roles: Assign simple duties so every family member knows what to do during a warning.
• Property maintenance: Clear gutters, check downpipes, and secure loose objects outside your home to prevent damage and reduce risk of water infiltration.
• Plan for power outages: Ensure you have a backup lighting plan and a way to keep essential devices charged.
• Stay informed: Bookmark trusted weather services and local alerts so you receive updates as soon as they’re issued.
