These networks are essential for connecting new housing and commercial developments to the wider gas infrastructure. Understanding the role of IGTs, how they differ from Gas Distribution Networks (GDNs), and the process for securing new gas connections through them is crucial for property developers, construction managers, and industrial clients. Understanding how gas networks, including independent gas transporters, connect to your home helps you make informed energy choices. Fuse Energy aims to make managing your home's energy simple and transparent.

These companies are responsible for the physical infrastructure that delivers gas from the larger regional Gas Distribution Networks (GDNs) to individual properties within new developments. IGTs do not sell gas directly to consumers; instead, they charge energy suppliers for the use of their infrastructure to transport gas to end-users. ### The purpose and growth of IGT networks The role of IGTs emerged from the deregulation of the UK gas market, which aimed to introduce competition into the provision of gas network services. Their primary purpose is to connect new housing estates, commercial premises, and industrial sites to the existing national gas infrastructure. This allows for efficient expansion of the gas network into new areas, supporting property development and economic growth. ## IGTs vs gas distribution networks (GDNs) ### Key differences in ownership and operation The main distinction between IGTs and Gas Distribution Networks (GDNs) lies in their scale and ownership. GDNs are larger, regional networks that cover significant geographical areas across Great Britain, forming the backbone of the gas distribution system. IGTs, conversely, operate smaller, localised networks that branch off from these main GDNs, typically serving specific new developments. While GDNs are often historically established entities, IGTs are private companies that have entered the market to provide competitive network solutions for new connections. ### How IGTs integrate with GDNs IGTs integrate with GDNs by connecting their local networks to strategic points within the larger GDN infrastructure. This means that gas flows from the national transmission system, through the GDN, and then into the IGT's network to reach the end consumer. For property developers, this integration means that while they might directly engage with an IGT for a new connection, the IGT's network is still reliant on the broader GDN for its gas supply. ## Regulation and oversight of IGTs ### Ofgem's role in licensing and governance IGTs operate under licences granted by Ofgem, the UK's gas and electricity market regulator. Ofgem's role is to ensure fair competition within the gas network provision market and to protect consumers. This regulatory oversight covers various aspects of IGT operations, including network safety, service quality, and the charges applied to energy suppliers for using their networks. Ofgem applies Relative Price Controls (RPCs) to IGTs to ensure that customers on IGT networks do not face significantly higher transportation costs than those connected to the main GDNs. ### Industry codes and standards for IGTs IGTs are also governed by industry-wide codes, which set out the operational rules and commercial arrangements for gas transportation. These include the Uniform Network Code (UNC) and specific IGT codes. These codes ensure that IGTs operate consistently with the rest of the gas industry, promoting efficiency and interoperability across different networks. ## Securing a new gas connection with an IGT ### The process for property developers Property developers, construction managers, and industrial clients frequently engage with IGTs for new gas connections to their sites. The process typically involves several key steps: 1. **Assess requirements:** Determine the specific gas connection needs for the new development or infrastructure project. 2. **Research IGTs:** Identify and research IGTs that operate in the project's region or specialise in the relevant sector. 3. **Request proposals:** Obtain detailed proposals and competitive quotes from several suitable IGTs. 4. **Evaluate proposals:** Compare IGT proposals based on connection costs, project timelines, service level agreements, and long-term network charges. 5. **Appoint IGT:** Select an IGT and proceed with the detailed design, planning, and installation of the gas network. 6. **Coordinate connection:** Work with the IGT and the chosen energy supplier to ensure final connection, coordinate meter installation, and gas supply activation. ### Key considerations for project planning and timelines When planning new gas connections via IGTs, it's important to consider potential complexities and timeframes. Underestimating these can lead to project delays. Factors such as the scale of the development, the distance from existing GDN connections, and the specific requirements of the IGT can all influence the project timeline. Thorough planning and communication with the chosen IGT are essential to manage expectations and ensure a smooth connection process. ## Benefits and practicalities for developers ### Advantages of using an IGT for new developments Engaging with an IGT for new gas connections offers several advantages for property developers. IGTs often specialise in new developments, providing tailored solutions and potentially more flexible project management compared to larger GDNs. Their competitive nature can also lead to more cost-effective proposals for connection costs and network infrastructure. ### Navigating proposals and contracts When evaluating proposals from multiple IGTs, developers should look beyond just the initial connection cost. It is crucial to understand the long-term implications, including ongoing network charges that will be passed on to future energy suppliers and, indirectly, to end-users. Service level agreements (SLAs) and project management capabilities are also vital considerations to ensure the IGT can deliver the project efficiently and reliably. Understanding your energy bill can help you keep track of these charges. ## Understanding your gas network ### Identifying your gas transporter For new developments, the gas transporter will be the IGT you have engaged with. For existing properties, identifying the specific gas transporter (whether an IGT or a GDN) can be done through your energy supplier or by using the [Find My Supplier](https://www.findmysupplier.energy/) service. Knowing your gas transporter is important for understanding network charges and for any network-related queries. Customers are free to choose and change their energy supplier. ### The wider energy ecosystem for new properties IGTs are a key part of the UK's gas supply chain, working alongside Gas Distribution Networks and energy suppliers. For new properties, understanding this ecosystem ensures a seamless transition from construction to occupancy, with reliable gas supply. While Fuse Energy does not provide IGT services or commercial gas connections, we are committed to supplying homes in new developments with clear, accessible energy services once they are connected to the network.
