How to wrap up for winter

As the temperature drops, the risk of a burst increases. Find out how you can best prepare

Did you know?

When temperatures drop below 0° water starts to freeze, amazing we know!

One day after a 16° drop in temperature we had almost 175 burst mains in one week alone. We've invested loads to try and stop as many burst mains as possible but if it gets that cold again we are likely to see mains bursting. Be prepared!

Why do pipes burst in winter?

When water freezes, it expands by nearly 10%. This can put a lot of strain on pipes, particularly when there’s fast changes in temperature.

Spend a fiver, save £9,000

According to the Association of British Insurers, a burst pipe will on average see you out of pocket by £8,800.

Some home insurers will only cover the cost of a burst if you’ve lagged your pipes, and even then, it’ll depend on your policy cover and excess. Lagging is cheap, quick and easy.

Wrap your pipes with lagging

Just like your poor cold hands and feet in winter, the same goes for the pipes at the ends of your home. Lag your outdoor, garage and loft pipes. Fortunately, this is quick, easy and fairly cheap to do yourself. You can pick this up for a couple of pounds per meter in a DIY store.

Is there a tap dripping outside? Get it fixed

It’s important to fix it as it makes your pipes more prone to freezing because it is more exposed to the cold air.

Not in? Keep the heating on low

Hot, cold. Hot, cold. This sudden change in temperature can cause havoc on your poor pipes – particularly if they’ve frozen.

Instead of turning the heating off, set it to around 14 degrees to maintain a constant temperature. Maintaining a constant temperature, as opposed to heating from scratch shouldn’t make a noticeable difference on your energy bill.

Regularly service your boiler

Servicing your boiler regularly is important for three reasons: keeping it efficient - so it can keep you warm better, household safety - so you can keep that 70 degree water under close supervision and keeping your warranty intact - remember that most boiler warranties require you to get your boiler serviced every 12 months.
