How Much Does a New Gas Supply Cost?
Typical costs for a new gas supply connection in the UK range from £2,000 to £4,000.
However, the prices you're quoted will depend on the property's distance from the mains, property type, and whether you're using a Gas Distribution Network (GDN) or an Independent Gas Transporter (IGT).
Many homeowners consider installing a mains gas connection for several reasons.
You might have just moved into a property that's never been connected before, you may be building a new home, or you could be switching from electric heating to a gas boiler and radiators.
While the upfront cost of a new gas connection can seem high, mains gas is generally far more cost effective than electricity in the long term.
Connecting to the gas network is a complex process, so it must be carried out by qualified specialists.
If your property is not already connected, you'll need to apply through a Gas Distribution Network (GDN) company, which manages the mains supply in your region.
Alternatively, you can ask for your quote to be split between contestable and non-contestable work, and get a separate quote from a Utility Infrastructure Provider (UIP) for the contestable part.
Gas Connection Prices
| Job Description | Duration | Typical Cost |
|---|---|---|
| Reconnection to existing mains supply | 2 to 4 weeks | £400–£700 |
| New connection within 23m of mains | 6 to 8 weeks | £500–£1,000 |
| New connection over 23m from mains | 8 to 12 weeks | £2,000–£4,000 |
| Additional trenching/reinstatement | varies | £500–£1,500 |

Factors Affecting Gas Connection Costs
- Distance from Mains — Longer distances require more piping and trenching, increasing costs.
- Ground Type — Digging through roads or concrete is more expensive than soil or grass.
- Provider Choice — A Utility Infrastructure Provider (UIP) can quote for contestable work.
- Additional Work — Reinstatement, internal pipework, and appliance installation such as a gas boiler add to the total cost.
What's Involved in Getting Gas Connected to Your Home
Getting gas connected to your home is not a DIY job. The connection to the mains is carried out by the network operator, and you must have a Gas Safe registered engineer carry out any pipework and appliance installation inside the house.
With MyJobQuote, you can request several quotes from local gas engineers. It's fast, free, and there is no obligation to go ahead.
Here's a broad overview of what to expect when connecting your house to the mains gas network:
Before the Job Starts
- Check for Previous Connection — Check if the property has previously been connected to the gas network.
- Request a Survey — Identify your regional gas network operator (GDN) and request a survey. They'll assess the route and confirm whether highway restrictions or local traffic management will be required.
- Compare Quotes — Ask for your quote to be split between contestable and non-contestable work, so you can get a separate quote from a Utility Infrastructure Provider (UIP) for the contestable part.
During the Job
- Gas Installation — The gas network operator carries out the gas installation according to regulations.
- Internal Pipework — A Gas Safe registered gas engineer installs internal gas pipes, radiators, and a combi boiler.
- Gas Meter Installation — Once the connection is complete, you'll need to contact a gas supplier to arrange gas meter installation before any appliances can be used.
After the Job
- Final Inspection — A final inspection is carried out and the gas is activated.
Key Things to Consider Before Connecting Gas to Your Home
Connecting a house to mains gas is a major decision, and could require a lot of work, depending on your property and the location.
- Was your home previously connected to gas? To connect gas to your home, you must be connected to the main gas grid. If your home was once connected to mains gas, it's a simple task of reconnecting to the existing mains gas network. Reconnections to the gas network shouldn't cost too much money, with an average cost of around £500. A brand new connection will cost more, and getting a new supply line from the gas grid can cost several thousand pounds.
- What is contestable and non-contestable work? Part of the connection can only be carried out by the local GDN and is classed as non-contestable work. The rest is contestable, meaning you can get a quote from a Utility Infrastructure Provider (UIP) for those parts, so it is worth asking for your quote to be split between the two.
- How close are you to the nearest mains? The proximity of your home to the nearest mains will be one of the biggest cost factors. If neighbours already have gas, you're likely close to a main gas line. In rural or remote areas, costs rise because new pipes may need to be laid over long distances.
- Which gas network operates in your area? There are currently eight gas distribution networks covering Great Britain, run by Cadent, Northern Gas Networks, SGN, and Wales & West Utilities. Northern Ireland has its own separate networks. You can find out which one covers your area online in minutes. IGTs also operate smaller gas networks alongside the main GDNs.
Checklist: Hiring a Gas Engineer for Running Gas to Your Home
Consider these key points before hiring a gas engineer for your gas installation:
- Are they Gas Safe registered? It is a legal requirement in the UK for any engineer carrying out gas work to be on the Gas Safe Register.
- Are they a member of IGEM? The Institution of Gas Engineers and Managers is the professional body for gas engineers in the UK.
- Do they have experience with gas installation? Gas installation work differs from standard boiler or pipework jobs. Check they have relevant experience.
- Do they have insurance? Public liability protects you if something goes wrong during the gas installation.
- Will they provide an itemised quote? Ask for a full breakdown of costs, so you know what is included and whether there are any additional fees you need to consider.
- Do they have examples of similar work? Ask to see previous gas installation jobs or check the photos on their MyJobQuote profile.
- Do they have positive reviews? Check their MyJobQuote profile to read feedback from previous homeowners.

FAQs
Who Do I Need to Contact to Get a Gas Supply to My Property?
To start running gas to your property, you will need to contact the regional Gas Distribution Network to evaluate the job and carry out the work for you. GDNs own and run the gas mains in your region, so you will need to contact them to get connected.
Can I Hire a Different Company to Connect My Property to a Gas Supply?
Yes, you can. Instead of going to your GDN for the contestable work, you can go to a Utility Infrastructure Provider (UIP), as GDNs hold a monopoly on the network.
A UIP is only authorised to carry out some aspects of the job, and the network may need to approve or inspect what they do. The rest of the work will still need to be completed by the GDN.
Can I Run a Gas Supply to My House Without Hiring a Specialist?
Unfortunately, you cannot undertake this work as a DIY project. Getting gas connected to your house requires access to the gas supply in your area, and you are not authorised to do that. You will have to contact the regional GDN.
What Is a Gas Meter Point Reference Number (MPRN)?
A gas Meter Point Reference Number (MPRN) is a unique number that identifies the gas connection point at your address. You will need to provide your MPRN when contacting a gas supplier to arrange gas meter installation. If you don't know your MPRN and your property already has a gas supply, you can look it up online using the Find My Supplier service by entering your postcode.
What if My Home Is More Than 23 Metres from the Gas Main?
If your home is within 23 metres of the nearest gas main, the gas network operator is legally required to connect you, but you may still have to pay for the pipework. If your home is further away than 23 metres, the operator can quote for the work, but they are not obligated to do the job. The cost will depend on the distance, ground conditions, and whether the gas line crosses any roads or pavements.
If this is the case, it's worth getting quotes from an IGT as well as your regional GDN, as gas pipes laid on private land are contestable work.
