The gas network in the UK and Ireland comprises around 300,000km of pipes – enough to go around the world seven times
The electricity network in the UK and Ireland comprises around 1,000,000km of cables – enough to go around the world 25 times
Energy network operators own and operate the wires and pipes that carry electricity and gas to your home. Sometimes you'll hear the networks being referred to as 'the grid'.
Transmission networks are the 'motorways' of the energy networks. They carry high-voltage electricity and high-pressure gas across the length and breadth of the country.
Distribution networks are the 'A-roads'. They carry gas and electricity into your homes. Electricity substations and gas pressure reducing stations convert energy so that it can be carried along the local distribution network. These local networks run at lower voltages and pressures, delivering electricity and gas safely into your community.
Around 30 million homes and businesses are connected to the electricity networks
Around 22 million homes and businesses are connected to the gas networks
The energy networks account for under a quarter of the average annual UK energy bill1
The energy networks are helping turn the tide on climate change.
We're the backbone of the UK's push towards Net Zero.
More renewable electricity and gas than ever is being produced and used across the UK and Ireland.2 The ways in which we travel, and heat and power our homes and businesses, are changing as new technologies, such as electric vehicles, become more popular.
The energy networks are responding – investing, innovating and helping to make all of this possible. We’re creating the world’s first zero carbon gas grid and using data and technology to create a smart grid that will enable more renewable energy to be generated.
Industries and sectors are becoming increasingly interconnected. Our power, heat, transport, waste and industrial sectors are all interdependent, so the solutions for their decarbonisation must be too.
Digital and technological innovation is helping network operators to manage the national uptake of electric vehicles, connect more offshore wind and renewables, and reduce the emissions of our heating systems.
Since 2015, the number of public charging points has grown by 402%3
In order to hit our climate targets in the most efficient and least disruptive way, we will need to reduce the emissions of our gas networks.
Our Gas Goes Green programme is showing how we can change the country’s extensive gas network and create the world’s first zero carbon gas grid. We will be using hydrogen and other low-carbon gases to heat our homes, and play a vital role in heavy goods vehicles, trains and planes.
Around 85% of homes in Great Britain are connected to the gas network4
Moving to a zero-carbon gas grid will help save bill-payers £89bn by 20505
To help homes and businesses take full advantage of new technologies such as electric vehicles and heat pumps, our Open Networks project is underpinning the delivery of an even smarter, more efficient grid.
New businesses will open and others will diversify as we build on our world-leading innovation in smart grids, technologies and services. In the future, these businesses could also see their products exported globally.
£8bn a year could be saved by networks investing in innovative new technologies6
Investing in smarter systems and greener gas presents opportunities for jobs and growth. Network operators are focused on recruitment which represents their communities and inspires a new generation.
400,000 jobs will be needed by 2050 to deliver the UK’s emissions targets.7 More jobs will be needed within the energy networks, the supply chain and in the new services and industries that emerge.
Around 45,000 people work in the UK and Ireland's electricity and gas networks
Our apprenticeship programmes support more than 1,200 people across the UK
Protecting the environment and ensuring safety are at the heart of network operators’ priorities. That includes both the safety of the public, and the workforce that maintains and operates the networks.
On behalf of the whole energy industry, we run the Powering Improvement health and safety strategy. Working with companies across the sector, unions and HSE, the programme has been instrumental in helping to keep everyone safe.
The new hydrogen-ready gas mains could save 240,000 tonnes of carbon a year8
The carbon intensity of the electricity networks has been cut by the equivalent of 850,000 tonnes of carbon in two years9
The electricity and gas networks in the UK and Ireland are designed to be highly resilient. However, sometimes problems occur that affect your energy supply.
If you smell gas or suspect a gas leak, you should immediately call the National Gas Emergency Service number on 0800 111 999 (In Northern Ireland, it's 0800 002 001 and in the Republic of Ireland, it's 1850 20 50 50).
If you have a power cut, or to report damage to power lines, call 105 for free (In Northern Ireland, it's 03457 643643 and in the Republic of Ireland, it's 1850 372 999).
The number of power cuts has fallen by 14% since 2015, while their length has fallen by 10%10
Seven million people have already signed up to the free Priority Services Register. If you need extra help, the free service provides access to additional support in an emergency, as well as accessible information.
As gas is often the cheapest way to heat a home, the gas network companies can help those who are not connected to the gas grid and may be having difficulties paying their bills, by providing funding toward the cost of connecting to their networks.
Average customer service scores for the energy networks are nine out of ten11
Around 97,000 fuel-poor customers will be connected to the gas networks between 2013-202112
Between 2013 and 2021, the GB network companies are spending and investing around £60bn, making sure that homes and businesses across the country are powered and heated. Customers are at the heart of their approach.
They will continue to focus on providing you with a secure supply of energy while enabling decarbonisation that has seen the UK experience its longest period without burning coal to generate electricity since the Industrial Revolution.
The Powering Improvement safety strategy has led to significant advances in staff safety and wellbeing. It is now entering its next five-year phase, while the companies are also innovating and investing in new systems and infrastructure to help protect the environment.
Protecting people and the environment we live in continues to be a priority for the network companies – and the energy networks have never been safer.
People who work for the electricity networks are more than 10 times safer than they were in 199013
The energy networks have never been more reliable and resilient while the levels of customer support have also never been better.14
Since 2008, GB networks have invested £1.2bn on 1,160 innovation projects. A relentless focus on innovation will help to improve reliability, while keeping costs down for the public.
The cost of transporting a unit of electricity around Britain has fallen by 17% since the mid-1990s15
We are redesigning the way our grids work which will help us to connect even more renewable energy projects more quickly than ever, while also providing you with a sector-leading service.
Private investment has helped to make Britain a superpower in renewable energy. We are building on that by enabling new, local energy markets, getting gas green and decarbonising transport. The networks have never been greener.
Over a quarter of our electricity generation and 100 green gas production sites are now connected to the local energy networks16
