the 10 ways to prepare your home now

By now, I’m sure you’ve heard the words El Niño thrown around a lot. The weather phenomenon has taken over news outlets and social media, with some coverage making it sound like an apocalyptic event. Thankfully, I’m here to put a few things straight. No, it isn’t the end of the world, but yes, it is pretty major.

El Niño isn’t a one-off storm, but a naturally occurring weather pattern that develops every two to seven years across the central and eastern tropical Pacific Ocean. This particular event is attracting so much attention because experts are predicting it could be the strongest in more than a century, with its effects expected to increase the chances of wetter and stormier weather across the UK this autumn and winter in a way not seen before.

Understandably, that has left many of us wondering what El Niño actually means for our homes, and whether there’s anything we should be doing now to prepare. I’ve been speaking to meteorologists and home and building experts to find out what this weather event involves, what the UK can expect and the simple precautionary measures we can all take to help protect our homes when the storms arrive.

What is the El Niño weather event?

‘El Niño is a natural climate pattern caused by unusually warm ocean temperatures in the central and eastern tropical Pacific,’ explains Emmy-award winning meteorologist and president of Monarch Weather Consulting Crystal Egger.

It isn’t a storm, or something that arrives in one dramatic swoop. Instead, it begins when the trade winds that usually push warm surface water westwards weaken or change direction. This allows warmer-than-usual water to spread across the central and eastern Pacific, releasing extra heat and moisture into the atmosphere.

That additional heat can disrupt air currents and jet-stream patterns, creating a domino effect that influences weather thousands of miles away. The impact varies depending on the region, with some countries experiencing drought and extreme heat, while others face heavier rainfall, flooding or an increased risk of storms. So, while it starts as an ocean temperature shift in the Pacific, its effects can ripple across the globe, like a butterfly effect it may seem so far removed but also what makes this weather pattern so significant.

‘Because the atmosphere and oceans are connected, a strong El Niño can shift jet-stream patterns and influence weather thousands of miles away. This year’s event is particularly notable, with forecasts suggesting it could be one of the strongest El Niños in more than a century,’ says Crystal.

Climate change has raised temperatures across the atmosphere and oceans, meaning El Niño’s heat is being added to an already warming planet and can make certain extremes, such as heatwaves and heavy rainfall, more severe. So climate change hasn’t directly caused El Niño, but it may be making the consequences of a particularly strong event more intense.

How will it affect the UK?

‘The important thing to remember is that El Niño doesn’t mean everyone gets the same weather. It changes the odds; it doesn’t write the forecast.’ That’s according to meteorologist Cheryl Nelson. So, what does it mean for us? Will we be getting heatwaves or floods? Unfortunately, it’s more likely the latter. As the Met Office refers to what is going to hit the UK as ‘unprecedented’.

‘The UK is a long way from the Pacific, but El Niño can still shift the odds of the overall weather patten,’ says Crystal. ‘With this year’s particularly strong El Niño, the Met Office is seeing a greater chance of wetter, windier and milder conditions across the UK this autumn and into early winter. Later in the winter, that pattern can shift toward a greater risk of colder conditions,’ claims Crystal.

In practical terms, this could mean more persistent rain, stronger winds and a higher chance of storms putting pressure on roofs, gutters, drains, trees and already vulnerable parts of our homes. Later in the season, a switch to colder weather could also increase the risk of frozen pipes and heating problems. It’s not a forecast for one endless UK-wide storm, but it is a good reason to get ahead of the basic home maintenance jobs that are much easier to tackle now than during a downpour.

How can you prepare your home now

El Niño won’t bring hurricanes or tornadoes to the UK, but it could increase the chances of wetter, windier and more unsettled weather. That makes now a good time to deal with the small maintenance jobs that can prevent bigger problems later.

‘You can’t control the weather, but you can make your home more resilient to it,’ advises Crystal. ‘A little preventative maintenance before the season begins can make a significant difference when extreme weather arrives.’

Check your roof

Your roof is one of the first parts of your home to feel the effects of strong winds and persistent rain, so don’t wait for water to start dripping through the ceiling before checking it. Look for missing, cracked or slipped tiles, damaged flashing, sagging gutters and moss or debris that could be hiding a problem.

‘Check your roofline before and after any bad weather,’ suggests Jonathan Ambrose, founder of Dronesurveyors.co.uk. ‘Missing tiles, sagging gutters, damp patches on ceilings or upper walls are usually the first signs that something’s wrong.’ Never climb on to the roof yourself. If you spot a problem, arrange for a qualified roofer to inspect it safely.

Clear your gutters and drains

This is one of the simplest and most worthwhile jobs to do before the autumn leaves begin to fall. Remove leaves, moss and debris from gutters, then check that downpipes are clear and directing water away from your walls and foundations.

‘Gutters are the big one,’ says Jonathan. ‘Blocked gutters mean water ends up running down the wall or into the roof structure instead, and that’s when small issues turn into expensive ones.’

While you’re there, check drains around the property and clear away anything stopping water from flowing freely. If you notice damp patches, discolouration, a musty smell or mould indoors, investigate the cause rather than simply painting over it.

Make the garden storm-safe

High winds can turn ordinary garden items into dangerous projectiles, so secure or store anything that could be lifted, blown over or damaged. This includes garden furniture, plant pots, trampolines, children’s toys, washing lines, sheds and fences.

‘Make sure trees are healthy and remove dead or weak branches that could become a problem during high winds,’ says Crystal. ‘Don’t forget sheds, fences, trampolines and other outdoor items that can become hazards in strong winds.’

For larger trees or branches near your home, power lines or neighbouring properties, use a qualified tree surgeon rather than attempting the job yourself.

Prepare for power cuts

Storms can bring power cuts, so put together a small emergency kit before you need it. Keep torches, spare batteries, portable chargers, warm blankets, bottled water and essential medication somewhere easy to find.

Cheryl also advises households to know how they will receive weather alerts if the power goes out. If you use a generator, make sure you understand how to operate it safely. Never use one inside your home, garage or another enclosed space, as it can produce deadly carbon monoxide.

Check your chimney and external walls

Look for loose chimney pots, damaged pointing, cracked render or gaps around windows and doors. These can allow rain into the property or become a problem during high winds. Arrange repairs early, particularly if you live in an older home.

Seal draughts and gaps

Check around windows, doors, vents and pipework for gaps where wind-driven rain could get in. Weatherstripping and sealant can help with minor gaps, but anything larger or linked to damp should be assessed professionally.

Check your boiler and heating

Remember, it’s not just about wet and windy weather. El Niño could also bring plummeting temperatures this winter. Have your boiler serviced if it is due, bleed radiators and make sure heating controls are working properly before colder weather arrives. This is particularly important for older households or anyone relying on a boiler for hot water and heating.

Make a plan if you’re going away

If you’re planning to travel during autumn or winter, think about what would happen if a storm hit while you were away. Ask a trusted neighbour or friend to check on the property, bring in post, secure anything in the garden and contact you if they spot a leak or damage.

‘What happens if you’re away from home when severe weather hits?’ asks Cheryl. ‘Make sure someone knows the plan, pets are accounted for and you have the essentials you might need if you can’t get home straight away. You want a plan that still works when things don’t go exactly as expected.’

Protect vulnerable pipes

Cold weather later in the winter could increase the risk of frozen or burst pipes. Insulate exposed pipework in lofts, garages and outbuildings, find your stopcock and make sure you know how to turn off the water quickly in an emergency.

If you rent, report problems early

Renters may not be responsible for repairing the roof, gutters or structure of a property, but it’s still important to flag problems before bad weather arrives. Take photographs of any existing disrepair, including cracked tiles, leaks, damp patches, blocked gutters or insecure fences, and report it to your landlord or housing association in writing.

‘Renters should document any existing disrepair and report it to their landlord or housing association early,’ says Jonathan. ‘It protects you and helps repairs happen more quickly.’

Keep copies of your messages and photographs, particularly if the issue could become worse during heavy rain or strong winds.
