New Business Gas Connection: Costs, Timeline & Process 2026

New business gas connection, what’s involved and how long it takes

If you’ve taken on a business premises that has never had a gas supply, you need a new business gas connection. This isn’t the same as a meter install, there’s no existing pipework, so the gas transporter has to physically connect your site to the local gas network before anything can be metered or billed. It’s a project, not a transaction.

Here’s how it actually works in 2026.

What does a “new gas connection” actually mean?

A new gas connection requires three things in sequence:

1. A new service pipe running from the gas main in the street (or estate distribution network) to your meter position.
2. An MPRN issued for the new supply point.
3. A meter installed and commissioned by a MAM.

Only when all three are done can you contract with a supplier to start billing.

Who is involved in a new business gas connection?

• Your Gas Transporter, either the regional Gas Distribution Network (Cadent, Northern Gas Networks, SGN, Wales & West Utilities) or an Independent Gas Transporter (iGT) on certain newer developments. They install the service pipe.
• A Meter Asset Manager (MAM), installs the meter once the pipework is in.
• Your Supplier, bills you for the gas once the meter is live. Chosen at the end of the process.

Most businesses don’t realise the gas transporter is a separate organisation from the supplier. They are. The transporter owns the physical network; the supplier just sells you the energy that flows through it.

How do you start a new business gas connection?

The first step is a gas connection enquiry, submitted either to your regional GDN or, if your site is on an iGT-managed development, to the relevant iGT. You’ll need:

• The site address and postcode
• A site plan showing your preferred meter position
• An estimate of your expected gas demand (in kWh/year or in m³/hour peak load)
• Confirmation that you have permission to install

The transporter then issues a connection quotation, typically within 6 to 8 weeks of the enquiry. The quote sets out the cost of the service pipe install, the lead time, and which parts of the work are contestable vs non-contestable.

What is contestable vs non-contestable work on a new gas connection?

This split is worth understanding because it can save you serious money:

• Non-contestable work, only the GDN or iGT can do this. Includes the actual connection to the main, the safety testing, and the final commissioning of the supply.
• Contestable work, anyone qualified can do this. Includes the trenching, the laying of the service pipe, and the civils. Independent Connection Providers (ICPs) can quote for contestable work, sometimes 30 to 50% cheaper than the GDN.

For a site-specific cost GDN quote, the contestable portion might be site-specific cost. An ICP might do it for site-specific cost. That’s site-specific cost of savings on a single connection.

What drives the cost of a new business gas connection?

Indicative ranges only. These are not live quotes. Costs depend on distance from the gas main, ground conditions, traffic management requirements, planning consents, and any wayleave fees.

How long does a new business gas connection take?

Total: 8 to 16 weeks for standard urban sites.

How do you project-manage a new gas connection?

1. Submit the connection enquiry early. Don’t wait until you need gas live. Aim for 12 weeks before you actually need supply.
2. Be flexible on the meter position. A meter position that minimises trenching distance from the main can shave thousands off the cost.
3. Compare GDN and ICP quotes for the contestable work. This is where the real savings live.

How does Clearsight help with a new gas connection?

We project-manage the whole thing: submitting the enquiry, getting the GDN quote, sourcing competing ICP quotes for the contestable work, scheduling the install, coordinating with the MAM for the meter, and contracting your supply onto a competitive supplier once the MPRN is issued.

No upfront fees. We’re paid by the suppliers we recommend.

How does a new gas connection application move through the network?

A new business gas connection moves through five stages, and the gas transporter, either a regional Gas Distribution Network (GDN) or an Independent Gas Transporter (iGT), controls the timeline for the first four.

1. Pre-application enquiry

Send the gas transporter a postcode, expected gas demand in kWh per year, and your timing. They return an indicative cost and timeline. This is the best way to find out early whether your site is close enough to the existing main for a standard short job, or whether the work runs to a mains extension.

2. Formal application and design

You submit the full application with site address, gas demand profile, and any constraints. The transporter designs the route from the existing main to your premises. Design fees apply on commercial applications and reflect the work needed to produce the plans.

3. Quote and acceptance

The transporter issues a quote covering the design, the network work, and the proposed timeline. You accept and the works get scheduled.

4. Civils and commissioning

The gas transporter runs the service pipe from the existing main to your premises and commissions the supply. Distance to the main is the single biggest driver of how long this takes. Sites close to the main are the standard short job. Sites further out or requiring main extension or reinforcement take meaningfully longer.

5. Meter install and supplier contract

The Meter Asset Manager (MAM) installs the gas meter. The MPRN is issued. You appoint a supplier and the supply goes live on a contract.

GDN or iGT? Which gas network owns your site?

Gas distribution is owned by four GDNs plus a growing number of iGTs. Cadent covers the largest area: North West, West Midlands, East of England, and London. SGN covers Scotland and the South. Northern Gas Networks covers the North East, Yorkshire, and Northern Cumbria. Wales and West Utilities covers Wales and the South West. iGTs sit alongside the GDNs, mostly on newer housing and industrial developments. iGT-managed connections are often quicker on new-build estates than the GDN equivalent.

What commonly delays a new business gas connection?

The avoidable delays are demand miscalculation (under-stating expected use means a smaller pipe is sized and then needs replacing), missing wayleaves on the route the pipe needs to take, restricted site access, sequencing errors with the meter and supplier, and main reinforcement triggered by your demand. Catching reinforcement risk in pre-application saves the most stress.

What do you need ready before you apply for a new gas connection?

A first call moves faster if you bring the basics: site postcode, expected gas use (kWh per year, or your best estimate of demand for heating, hot water, and any process load), what the site does today and what it will do after the install, planned move-in date, and any deadlines. If you do not have all of this, we can fill the gaps once we have the postcode.

What happens after the gas meter is live?

Once the MPRN is issued and the meter is in, you can put the supply onto a competitive contract. See our guides to business gas and switching business gas supplier. For sites with high daily gas use, see our notes on Daily Metered (DM) meters in the meter types section. For the full pillar covering every meter install and connection scenario, see our business meter installation and new connections hub.
