Gas leak repair cost guide

Gas leaks can be fatal. So, if you think you have a gas leak, it’s vital that you get it dealt with straight away. Here, we’ll take a look at what to do, the average gas leak repair cost and the best ways of preventing a leak from occurring in the first place.

The average labour cost to repair a gas leak is £165. But the total cost can vary massively depending on the cost of materials and the amount of time it takes to repair the leak.

Plus, don’t forget that fixing a gas leak will usually be an emergency repair which can drive up prices. You’re likely to pay more if you have to call someone out in the middle of the night for instance, or on Christmas day.

Can I do a natural gas leak repair myself?

When you’re dealing with gas, you will need to hire a Gas Safe registered engineer. It might look fairly straightforward to repair a gas pipe or install a new gas stove yourself, but this is illegal and mistakes can be dangerous or even deadly. An unfixed gas leak could even result in an explosion.

Fridge gas leak repair cost

Refrigerants like Freon aren’t commonly used in modern fridges because they harm the ozone layer. However, if you have an older fridge and it gets low on Freon, that’s a sign of a leak. Getting it repaired could cost somewhere around £150 to £225.

How do I know if I have a gas leak?

When natural gas first comes out of the ground, it has no smell. So, in order to make gas leaks easier to notice, gas companies add a chemical called mercaptan which smells like rotten eggs. This smell is usually the most obvious sign of a gas leak.

Other signs include:

  • A damaged gas pipe
  • A hissing sound near a gas line
  • A white cloud near a gas line
  • Dead houseplants
  • Bubbles in water
  • Higher gas bills than usual

If you believe you have a gas leak, evacuate the building immediately and don’t use any light switches or phones. As soon as you’re clear of the property, phone the emergency gas telephone line.

How can I prevent a gas leak?

Prevention is better than cure. Follow these simple tips to do everything you can to prevent a gas leak from occurring:
