Understanding gas supply in London

Many London residents assume their gas supplier handles everything, from the pipes in the street to their monthly bill. However, the system is more nuanced, involving distinct roles for network operators and energy suppliers.

The role of network operators versus suppliers

In London, the gas distribution network - the vast network of underground pipes that delivers gas to your home - is run by two Gas Distribution Network Operators (GDNOs): Cadent Gas covers North London, while Southern Gas Networks (SGN) covers South London. Whichever operator serves your area is responsible for maintaining these pipes, responding to gas emergencies, and connecting new properties to the network. They do not sell gas directly to you; they simply ensure its physical delivery.

Energy suppliers, such as Fuse Energy, are the companies that actually sell you the gas. They buy gas on the wholesale market, manage your account, send you bills, and handle customer service. Think of it this way: Cadent Gas builds and maintains the road, while your energy supplier sells you the vehicle and manages your journey. Ofgem, the UK's energy regulator, oversees both network operators and suppliers to ensure fair practices and protect consumers.

Identifying your gas network operator in London

Knowing your gas network operator is crucial for emergencies or new connections. Cadent covers North London and SGN covers South London, so it is always best to confirm. The Energy Networks Association (ENA) provides a postcode lookup tool that allows you to identify your local gas network operator. Simply enter your postcode, and it will tell you who is responsible for the gas pipes in your area. This is particularly useful if you need to report a gas leak or require work on the main supply line. If you are unsure who supplies your energy, you can also use online tools to find out who supplies my energy.

Getting a new gas connection in London

If you are building a new property, converting a building, or simply want to add a gas supply where there was not one before, you will need a new connection. This process involves direct coordination with your gas network operator.

The process for new gas supply

Getting a new gas supply in London typically involves several steps:

1. Contact your network operator: London's network is run by Cadent in North London and SGN in South London - confirm yours with the ENA postcode tool, then contact them as your first point of contact. You will need to provide details about your property and your connection requirements.
2. Quotation and survey: Cadent will assess the work needed and provide a quotation. This may involve a site visit to determine the best route for the new gas main and service pipe.
3. Acceptance and payment: Once you accept the quote, you will usually need to make a payment to initiate the work.
4. Installation: Cadent's engineers will carry out the necessary work to connect your property to the gas network. This involves laying pipes and installing a gas meter.
5. Choose an energy supplier: Once the physical connection is made, you will need to choose an energy supplier to activate your gas supply and start billing.

Costs and timelines for new connections

The cost and timeline for a new gas connection in London can vary significantly. Factors such as the distance from the nearest gas main, the complexity of the excavation work, and any necessary road closures will influence the price. Similarly, timelines can range from a few weeks to several months, depending on the scale of the project and the network operator's schedule. It is essential to get a detailed quote and estimated completion date directly from your gas network operator for an accurate understanding.

Switching your gas supplier in London

Even if you have an existing gas supply, you are not tied to your current provider. Switching suppliers can lead to better deals, improved customer service, or a provider that aligns more with your values.

Why consider switching your London gas supply?

The energy market is competitive, and suppliers constantly offer different tariffs and incentives. You might consider switching your London gas supply for several reasons:

• Better tariffs: Some suppliers offer more competitive unit rates or standing charges, potentially lowering your overall gas bill. Understanding your average gas and electric bill can help you compare.
• Improved customer service: Not all suppliers are created equal when it comes to support. If you are unhappy with your current provider, a switch could mean a better experience.
• Modern features: Many newer suppliers offer intuitive apps, smart meter integration, and transparent billing, giving you more control over your energy usage.
• Green credentials: While gas is a fossil fuel, some suppliers invest in offsetting programmes or offer a clearer path towards a greener energy future.

How to switch to a new gas supplier

Switching gas suppliers in London is generally a straightforward process:

1. Identify your current supplier: If you are unsure who supplies your gas, you can use the 'Find My Supplier' tool online.
2. Compare tariffs: Research and compare available gas suppliers based on their tariffs, customer reviews, and any additional services they offer.
3. Initiate the switch: Once you have chosen a new supplier, they will handle most of the switching process for you. You will typically provide them with your address, meter readings, and bank details.
4. Confirmation and cooling-off period: Your new supplier will confirm the switch, and you will have a 14-day cooling-off period, starting from your switch-in date, during which you can change your mind.
5. Final meter reading: You will usually be asked for a final meter reading on the day of the switch to ensure accurate billing from both your old and new suppliers.

Managing your gas supply: emergencies and support

Knowing what to do in a gas emergency and understanding the support available to vulnerable residents is vital for peace of mind.

What to do in a gas emergency

Gas emergencies, such as a gas leak or the smell of gas, require immediate action. If you smell gas or suspect a leak, follow these steps:

1. Open windows and doors: Ventilate the property immediately.
2. Turn off your gas supply: Locate your main gas isolation valve (Emergency Control Valve, or ECV) and turn it off if it is safe to do so.
3. Do not use electrical switches: Avoid turning lights on or off, using mobile phones, or anything that could create a spark.
4. Evacuate the property: Get everyone out of the building safely.
5. Call the National Gas Emergency Service: From a safe distance, call 0800 111 999. This service is available 24/7. Do not call your energy supplier for a gas leak or smell of gas; contact the emergency service directly.

If you have no gas supply but do not smell gas, this is not considered an immediate emergency. First, check if your neighbours have gas, as this can indicate a wider network issue. If it is only your property, check your meter and any prepayment balance if applicable. You may need to know how to enable gas supply from a smart meter if you have one. If the issue persists, contact your energy supplier for assistance.

Priority Services Register for London residents

The Priority Services Register (PSR) is a free support service that helps energy suppliers and network operators look after customers who are in a vulnerable situation. You may be eligible if you:

• Have reached state pension age.
• Are disabled or have a long-term medical condition (including mental health conditions).
• Are recovering from an injury or recent hospital stay.
• Have a hearing, sight, or smell condition.
• Rely on medical equipment that uses electricity.
• Are pregnant or have children under five.
• Have extra communication needs, such as if you do not speak or read English well.
• Are experiencing a temporary situation where you may need extra assistance.

Registering ensures you receive extra support during power cuts or supply interruptions, such as priority updates and alternative heating or cooking facilities if needed. You can register for the PSR through your energy supplier.
