Domestic gas connections: what you need to know

If you're looking to set up a new domestic gas connection or need to alter an existing gas connection, you may be unsure where to begin.

So we've put together some help and advice about gas connections, where you can learn how to:

  1. Find out which gas network your property is covered by
  2. Arrange a gas connection or alteration with your gas network
  3. Obtain a gas meter for your home
  4. Order a meter box spare or organise a repair

The basics

Firstly, a couple of things you should know about gas connections and how gas is supplied to domestic properties in the UK:

  • Gas suppliers
    The gas in your home is provided by a gas supplier, who must be licensed by Ofgem to sell gas. Gas suppliers sell gas directly to consumers.
  • Gas networks
    Gas connections and alterations for domestic properties are arranged by gas networks, such as National Grid. Gas networks don't sell gas – they provide consumers with the means to utilise gas in their homes.

How to set up new domestic gas connections

In order to set up a new gas connection for your home, you'll need to find out which gas network your property falls under. This will vary depending on the area in which you live.

The UK mainland gas network is divided up into eight separate gas networks. Take a look at the list below to find out which network your property is covered by.

  • National Grid
    • East of England
    • North West England
    • West Midlands
    • London
  • Northern Gas Networks
    • North of England
  • Scotia Gas Networks
    • Scotland
    • South England
  • Wales and West Utilities
    • Wales
    • South West England
  • Independent gas transporters
    If your local gas main is part of an independent gas transporter (IGT), you'll need to contact that specific IGT to request a new gas connection.

Ordering a new gas meter

To order a new gas meter for your home, contact your gas supplier. There are a range of different types of meters available (e.g. wall-mounted, semi-concealed, standalone) so ask your supplier for more information if you're unsure which is best for you.

New gas meters and dealing with gas meter problems

If you're looking to install a new gas meter in your home or need help with a gas meter problem, a few useful tips are as follows:

  • Gas meters in new properties
    If you've just moved into a new property which has never had a gas meter installed before, you'll firstly need to check that you have a gas connection. If so, you can obtain a new meter from your gas supplier. If you need to arrange a new gas connection, see 'How to set up new domestic gas connections' above for further information.
  • Problems with your gas meter
    Your gas meter is provided by your gas supplier, so if you're having problems with your meter, you’ll need to contact your gas supplier.
  • Obtaining a replacement gas meter
    You can obtain a replacement gas meter for your home from most builders’ merchants. You may also require an alteration to your gas connection, for which you'll need to contact your gas network. See 'Altering gas connections' below for further information.

Altering gas connections

You may require an alteration to your gas connection if you need to move your gas meter or change your service pipe route, length or size. If this is the case, you'll need to contact your gas network to arrange the alteration for you.

To arrange a gas connection alteration for non-domestic properties, contact your gas network or take a look at the Ofgem website.

Obtaining meter box spares and repairs

If you require meter box spares or repairs for your domestic gas meter (such as hinge pins, locks or keys), you'll need to contact your gas network. When you call to arrange your repair or order a spare part, it's likely that you will be asked to provide some or all of the following information. So be prepared and make sure you have as much of the information listed below as possible before picking up the phone.

  • Your address and telephone number
    You'll need to provide the address of your home and a contact telephone number. If your property is a new build and has not yet been assigned an address, you'll need to register your property with the Post Office.
  • The location of your gas meter
    It'll make it easier for your gas network to understand your requirements if you can specify which part of your home your gas meter is located in.
  • Your Meter Point Reference Number
    You should be able to find your MPRN on your gas bill. Contact your gas supplier if you can't locate your reference number.
  • A correspondence address
    If your home hasn't been allocated an address yet, you'll be asked to provide an alternative address where any correspondence will be sent in the meantime.
