WALL challenges Ofgem to look again

This was not about the merits of the project overall, but about the rules that decide how much extra time LionLink can have to get built, and what happens if it is late. LionLink would be supported by Ofgem’s “cap and floor” scheme. If the project earns less than an agreed minimum, the shortfall is topped up and that money is recovered through charges that end up in electricity bills. That is why the economics matter to everyone, not just to people who live near the route.

The consultation closed on 15 October 2026. WALL has analysed the underlying economics of LionLink and, based on that work, sent Ofgem a detailed response on 13 October 2026. This note explains, in plain terms, what we have said and why.

What do Ofgem’s own figures show?

Ofgem’s own figures show British electricity consumers losing out. In November 2024, Ofgem’s own assessment found losses to consumers in every one of the three main scenarios it examined: between £3.1 billion and £6.1 billion over 25 years. These are not the same as a rise on your bill, but they show who loses out.

The project only looks positive because others gain more. Electricity generators and the link’s owners gain more than consumers lose, leaving a small overall surplus of £0.3 billion to £1.2 billion.

The numbers are unstable. In just eight months in 2024, Ofgem’s estimate for consumers in one scenario swung from a £3.5 billion gain to a £3.1 billion loss.

Local costs are not counted. Ofgem’s figures do not put a value on the harm to the protected Suffolk coast, including the Minsmere-Walberswick wildlife sites and the Suffolk and Essex Coast and Heaths National Landscape, or on tourism, local businesses, access to nature, and health and wellbeing. A surplus as small as £0.3 billion could easily be outweighed by costs that have not been counted.

 What has changed since?

 Ofgem assumed LionLink would start running in 2030. The rules now allow it to start as late as the end of 2035, in an energy market that may look very different.

National Grid has changed its plans again, proposing a third landfall site in Walberswick.

The government has asked for more information on Sea Link, the other major cable projecton this coast, after its public examination closed.

A new national energy plan, setting out what energy Great Britain needs and broadly where, is due in autumn 2027. LionLink has not been checked against it.

The National Audit Office has called for stronger oversight of how major grid projects protect bill payers.

 What is WALL asking Ofgem to do?

 1. Look again at whether LionLink still makes economic sense, using today’s evidence and taking into account the costs to local communities and the environment, and publish the result.

2. Explain what LionLink could mean for household and business bills, and who carries the risk if things go worse than expected.

3. Check LionLink against the new national energy plan before giving it more time or its final approval.

4. Build a proper check into the rules, so that a project’s case is tested again whenever circumstances change.

5. Make the 2035 deadline a real deadline, with no extensions beyond it, even for events outside the developer’s control, so that consumers are protected if the case for the project changes.

6. Be open about its decisions and the reasons for them.

 Where should LionLink connect?

WALL has always said that if LionLink has to come ashore, it should connect at an existing brownfield site, not in a small stretch of the Suffolk coast already crowded with energy projects. On the Dutch side, the cable is routed along existing waterways to an established energy hub. Suffolk deserves the same care.

Our Mission

WALL wholeheartedly supports the UK’s commitment to achieve Net Zero by 2050 and recognises the importance of renewable energy to achieving that goal.

However, WALL believes that National Grid’s proposal to land their LionLink interconnector cable on the Suffolk coast is driven primarily by reducing costs and boosting their profits.
It will result in irreparable damage to the beautiful natural environment surrounding Walberswick, reduce biodiversity and harm local businesses and the economy.

WALL opposes LionLink and believes that the best solution is for National Grid to create an offshore grid and bring cables ashore at an existing brownfield site closer to London and the South East, where demand for electricity is highest.

FAQs

What does Lion Link want to do?

LionLink proposes to bring ashore cables interconnecting the UK to Holland at one of two greenfield sites in Walberswick. These sites are at the beach hut car park or at Manor Field in the centre of the village. The huge earthworks to bury the cables will impact upon the beach, the dunes, the river, the marshes and the various protected lands that surround Walberswick.

How long will it take?

National Grid Ventures say the LionLink project could take 8 years to complete, beginning with the initial consultation in 2022 through to the interconnector cable coming into service in 2030. National Grid will probably decide on their preferred landfall site in 2024, start a statutory consultation in 2025, aim to get planning approval in 2026 and start construction in 2027. The process of constructing the landfall site (either G or G2) and then laying the cable to the proposed substation near Friston could take up to 4 years.

What does it look like?

This aerial photograph shows the same landfall process happening at Bawdsey 30 miles away. The image hasn’t been doctored… the cable route is as wide as a motorway.

What’s the alternative?

An offshore grid through the North Sea connected to brownfield sites closer to where the power is needed would create a sustainable, non-invasive solution that can be added to. Our North Sea neighbours in Belgium, Germany, Holland and Denmark are rolling these out… why can’t we?

Who is LionLink?

LionLink is a private company posing as a public one. They are accountable only to their shareholders so are not making decisions that are focused on the public good or the costs they impose on our communities.

Who is WALL?

Walberswick Against LionLink is a local campaigning organisation formed by a group of Walberswick residents opposed to National Grid’s LionLink proposal. It started as a WhatsApp group which grew to have over 230 members. WALL is run by volunteers who are organised through a Steering Group with sub-groups working on Communications, Fund-raising, Environment, Legal, Energy Strategy and other topics.
