You may need to get a property connected to a new gas or electricity supply, or want to alter the connection to the mains, if you:
- are building a new property or business premises
- are developing a generation site
- have moved to a new property and the gas or electricity doesn’t work
- want to move your energy meter.
Here we explain how to get connected, or change the connection. For information about moving your meter, see Understand your energy meter.
How to set up a gas or electricity connection
To get your property connected to a gas or electricity supply you’ll need to contact your local distribution network operator or ‘DNO’.
These are the companies that own and operate the infrastructure that delivers power and gas to your property. Most are regional monopolies, so you don’t get to choose your DNO; it’s based on your location.
You don’t have to use your DNO for all connection services. You can go to an independent connections provider or ‘IDNO’ for some services instead. IDNOs also own parts of the energy network.
Some parts of the work – termed ‘contestable work’ – could also be done by a registered gas engineer or electrician. This could help to bring down costs, but you must first check with the DNO or IDNO if this work will need to be agreed or inspected by them.
Gas or electricity connection costs
You’ll likely need to pay for the cost of a gas or electricity connection in advance. The cost will depend on factors including where you are located, how long it will take and the amount of energy you’ll need.
The price you’ll be quoted will cover:
- the costs of assets solely for your use
- a proportion of the cost of reinforcing the network, if needed.
The DNO must calculate the costs using its connection charging methodology. DNOs each publish these on their websites. Ofgem approves this methodology, but we don’t approve the individual charges it calculates for you.
What to expect from your DNO
Ofgem makes sure you are getting a high quality service at a fair price by setting the framework for each DNO to operate under.
Each DNO has a licence and we monitor performance against it. This includes requirements for DNOs to provide connections. It also encourages them to improve their performance in this are.
- Once the DNO has the information it needs, it must offer you terms for a connection within three months, including information on how the charge is calculated.
- Our Guaranteed Standards of performance measure if DNOs are meeting minimum requirements for specified connection services. A DNO must compensate you if it fails meet these standards.
- A DNO should provide transparent information to make it easy for you to connect, like a guide on the process.
- DNOs publish their complaints processes and are incentivised to deal with issues quickly.
Shop around for an energy supplier
You’ll need to choose a gas or electricity supplier to get a meter installed at your property and to bill you for your usage.
You should arrange this at the same time as sorting your connection with the DNO to avoid delays.
See our section on Shopping for a better energy deal.
This also includes advice on the different available energy tariffs.
Alter a gas or electricity connection
If you want to alter a connection, you should first contact your DNO or IDNO.
If you want to move your energy meter, you should contact your energy supplier.
It’s illegal to move your own energy meter. For more details, see Understand your energy meter.
If you aren’t happy with the service you receive from a network company and can’t resolve this with your distribution network operator, you can contact the Citizens Advice consumer helpline (opens another website). They can advise if you can refer your case to the Energy Ombudsman.
You can also refer a dispute you are having with your DNO to us to determine. The 'Authority' (our governing body) will make the determination. These circumstances are set out in statute, in particular, the Gas Act 1986 and the Electricity Act 1989 (the Acts) and in the licence obligations on network companies. See our Guide to determinations.
