Brits are expected to pour 3 million litres of oil down the drain at Christmas.

This Christmas 16 million adults will pour more fat, oil, and cooking grease down the sink.1

This is according to new research from home assistance provider, HomeServe, which found that collectively 3 million litres of oil will be disposed of incorrectly in December – Across the nation, a quarter of Brits (25%) routinely get rid of their cooking fat and oil down the drain and a third (30%) say they are likely to pour more down this Christmas, with Londoners set to be the worst offenders (42%).

HomeServe is today warning Brits to dispose of their oil correctly to avoid clogged up drains and emergency callouts as HomeServe internal data shows that blocked drain callouts increase by 23% in January compared to the average month. This is potentially due to putting an increased amount of oil going down the drain over Christmas.2

Plumbing & Water Supply Engineer, Liam Sharkey, at HomeServe comments:

“Pouring fat down the drain might seem an easy option, but it can wreak havoc with your pipes. Christmas is a time we tend to cook more hearty and fatty food, so it’s important to be extra vigilant when disposing of food waste such as meat juices. If they are poured down the plughole, they will solidify and risk leading to a blockage”.

Liam Sharkey from HomeServe offers his top tips on how to avoid sink blockages:

  1. Don’t pour fat, oil, or grease down the sink Food waste – particularly oil – should never be poured down the sink as it can lead to blockages in your pipes. Instead, wait for the oil to solidify and dispose of it in an old plastic container such as a margarine tub. This can then be put in your regular waste when it is full.
  2. Be aware of any smells coming from the plugholes A foul odour from your sink is a good indicator that food or waste may be trapped in the pipes and breaking down to form mould and bacteria. Sometimes, you can deal with the smell yourself by pouring a large cup of bicarbonate of soda down the plughole, followed by a cup of white vinegar. Let it sit for 20 minutes, and then pour down a kettle full of boiling water. It’s good to get in this habit once a week which should help keep your sink smelling fresh.
  3. Check your outside drain If blocked drains are a persistent issue, it may be that your outside drain is blocked, which can be caused by bigger debris such as branches or leaves. If you feel confident, you can lift your drain cover, and inspect inside. If you can remove any large items that you discover with the appropriate tools, then do so to clear any blockages but you should never enter a manhole or inspection chamber to do this.
  4. Call a specialist If flushing the plug holes with bicarbonate of soda, or checking your outside drains hasn’t done the trick, it’s time to call in a specialist. It may be that there’s a more functional issue with your plumbing systems which need to be inspected by a professional such as a loose pipe, or a drainage problem which needs to be rectified. Having some form of home assistance cover, particularly at a time when we know that callouts are busier, can help you keep on top of the issue.
