Building Over Gas Pipe Work

Part of our role involves making sure all our pipes comply with UK safety law. As instructed by the Health and Safety Executive (HSE) and recommended by the Gas Safe Register, building over or close to gas pipes should be avoided during any work on your home or business. 

We can help you to understand where your gas service pipe is located. It is important that you have the right information before you begin any building work to make sure you continue to receive a safe and reliable gas supply. 

Please contact our Gas Connections or Diversions team at the below links:

If you believe your gas pipe work is already built over, please contact our Customer Care team on 0800 040 7766 option 4 or email compliance@northerngas.co.uk
