How to Set Up a New Gas Connection and Supply

Gas flame between energy bills and savings

Whether you’re looking to set up a new gas connection in a new build home, you already have capped gas on the property needing to be reactivated, or you’re adding gas to a home that is currently electricity only, our guide will get you up and running in no time.

Just moved into a new-build house or business premises only to find there’s no gas supply? Perhaps you want to save money by hooking up gas for the heating and cooking in your current electricity-powered home? Either way, getting a new gas connection set up is easier than you may think.

If your home or business previously used gas, but this has since been ‘capped off’, see ‘My supply has been capped - how do I set up a new gas connection?’ further down the page.

1. Contact your local gas distributor

In order to have a new gas connection fitted, you first need to contact the gas distribution network that services your region. The gas distribution companies that manage the network can also be called gas transporters or distribution network operators (DNOs); however, the term DNO is more commonly used to describe electricity distribution companies.

To make the new gas connection process as simple as possible, make sure you have everything you need before calling the distributor:

  • Check the map and table below to find out who your local gas distributor is.
  • Find out how far away the gas mains are. The price could change dramatically the further away your house is to the mains, as the distributor might have to add extra piping, or reroute existing pipes to connect you to the main gas supply.
  • For new builds, you may need a site plan in order for the gas distributor to plan where pipes will be installed and meet the gas main.
  • Don’t forget to get permission from the landowner, if that person isn’t you!

How long does it take to connect gas?

If your distributor is unable to give you a quote for the new gas connection over the phone, they will arrange for a surveyor to visit your property to carry out an inspection and talk through any work that needs to be carried out.

You should receive a quote by email or post within 6-12 working days of contacting your gas distribution company. Should you accept the offered price, you will generally receive confirmation and a planned start date for the work within another seven working days.

Once the work is started, getting your home or business connected to gas usually takes between four and six weeks, though this is dependent on a range of factors (see below).

How much does it cost to connect to mains gas?

There are many variables that will determine the cost of setting up a new gas connection. Here are some of the key factors that can impact the cost and time you will need to spend:

  • How close your property is to the gas mains supply. The cost will increase the further away the mains are.
  • The condition of existing piping. If the pipes are not in good shape, it could cost more to deal with any delays or setbacks needed to bring the condition of the mains piping up to scratch.
  • If the company needs to access third party property, e.g. neighbours or roads, you will need an access permit to carry out any works. Also, the possibility of making a connection on a busy road and any resulting road closures can be very costly and time-consuming.
  • How much work is needed and whether third party contractors are required to complete any of it (although you can hire contractors yourself to keep the price down, where applicable).

The average full cost for a domestic gas connection is in the range of £2,500 – £5,000.

A new gas connection is usually more expensive to set up than an electricity connection. Gas appliances will often set you back more too, so that’s something to consider. Overall, the initial outlay for gas is higher, but running costs are cheaper, so you'll save money in the long run.

Generally speaking, gas is cheaper than electricity when it comes to paying your utility bills. However, the range of tariffs is eclectic, so it pays to research all the deals in the market to ensure you have the best rate based on your needs and lifestyle.

Don't accept the first price

When you receive your quote from your gas distributor, you don’t have to accept it. If you think it’s too high, ask the distributor for a breakdown of the quote.

Parts of the quote could be more expensive if there is additional work to be carried out by contractors. This is called ‘contestable work’. Review the work that is needed and search for your own quote for these works, to reduce the price. If you do find a cheaper price, the work will need to be inspected by the distributor to verify any labour done.

2. Find an energy supplier for your new gas connection

Because the distributors don’t actually own, meter or sell any gas, once you’ve got your new gas connection hooked up, it’s time to start searching for an energy supplier that best meets your requirements. This is the company that will be responsible for connecting your meter and sending you your bills.

Everyone has different needs when it comes to energy. The important questions to consider when choosing a gas provider are:

  • How much gas are you (and your family) likely to use?
  • Do you prefer to pay ahead of time for your gas each month and know in advance what you’ve spent or do you prefer to wait until you receive a bill?
  • What’s your driving factor when choosing a tariff - price or customer service and reputation?

Hopefully, you are getting closer to understanding whether a new gas connection fits the bill for you. From a financial perspective, it certainly pays to use gas for your heating and cooking - if you factor in the cost over a long period of time. Although it is initially more expensive to set up than electricity, a new gas connection will ultimately save you money on your utility bills.

My supply has been capped - how do I set up a new gas connection?

Sometimes an existing gas supply will be ‘capped’ for safety reasons, for example when a property has been left empty for a long period of time or if there has been a gas leak. Capping can also be done in order to remove a meter and avoid standing charges if a home or business doesn’t require gas.

If your supply is capped but you can smell gas or need to report a gas emergency, call 0800 111 999 immediately. This line is open 24 hours a day, seven days a week.

If you’re moving into a new property and require gas, or if you have previously capped your supply and now want a gas connection once again, you’ll need to check where the cap is to work out who to contact.

  • If the meter is capped on the incoming gas pipe or the emergency control valve, then you need to contact the gas distribution network in your area to find out why this has been done. If you’re unsure who is responsible for your local gas distribution, a Selectra energy expert will be able to point you in the right direction. Give us a call on get a free callback now.
  • If the cap is on the internal pipework, you (or your landlord or managing agent) will need to arrange for a Gas Safe-registered engineer to take it off.
