As Britain is battered by icy cold conditions, homeowners will be whacking up the radiator to try and stay warm - and there's a simple "one second" hack that can help prevent weather pipes from freezing over.

Cold weather can cause all sorts of havoc for people, but one thing nobody wants to happen is for radiator pipes to freeze over, and even worse, burst. The harsh weather can be a risk for radiators, and burst pipes can lead to leaks in your home - so here's what to look out for, and how to easily prevent it from happening according to British Gas.

They advised homeowners to listen out for "gurgling" sounds when the heating is on, as it could be a sign there are issues with the radiator pipes. They explained: "When temperatures drop below zero, the water in your pipes can freeze if they're not insulated properly. And since water expands as it freezes, it can put pressure on the pipe itself – causing it to buckle and split." Other signs may include your boiler not turning on, no water coming out of the taps or just a "trickle", as well as a clogged sink or a slow flushing toilet.

If you are going to be away while the freezing temperatures hit, Which? UK has shared some advice on what you can do to help prevent the freezing of your pipes and it takes just one second. They told The Express: "You should set the radiator valve to the 'frost' sign when your heating is on. This will allow just enough water into the radiator to keep the room above seven degrees so your pipes don't freeze."

British Gas assured people that if a frozen pipe is found, to not panic as there are a few things that can be done to help salvage the pipe and keep it from bursting. They warned that those with a modern condensing boiler are most at risk of having a "condensate pipe that is freezing over" which they described as "a plastic one that comes out of your boiler."

First, they advised to find the frozen pipe and thaw it out. They stated: "Slowly pour hot (but never boiling) water over the frozen pipe and place a hot water bottle over it to help melt away the ice." If you think you have a burst pipe, there are a few ways to spot one.

British Gas revealed the warning signs can be:

• Problems with your water pressure or trouble with your water flow
• Water marks or patches on your walls or ceilings
• Bulging walls or ceilings
• Damp patches on the floor.
