UK bill will allow gas companies to force entry into people's homes for hydrogen heating trials

British legislators plan to extend legal right of gas companies to enter private properties to make them safe as part of H2 trials — but say that they would only be used as a last resort

Legislators in the UK are working on a new bill that would grant gas suppliers and distributors more powers to force entry into private citizens’ homes if they’re located in an area that is taking part in a hydrogen trial — to the alarm of residents whose properties have been nominated for it.

Officials insist that the powers would only be used to ensure public safety, and only as a last resort.

The Energy Security Bill, which is currently in the early stages of passage through the UK Parliament’s upper house, the House of Lords, would extend existing powers of entry to allow gas companies to “ensure that consumers in the trial area can be safely connected to hydrogen instead of natural gas”.

The UK government has pledged to have a “hydrogen village” up and running by 2025, with the aim of testing and demonstrating hydrogen distribution across an existing natural gas network, as well as the use of the fuel in domestic heating and cooking.

Currently two gas distribution companies, Cadent Gas and Northern Gas Networks, are competing for public money to fund a hydrogen village in Whitby, northwest England, and Redcar in the northeast, respectively. Both projects are currently in the design phase, but the Whitby proposal is facing stiff and vocal opposition from local homeowners.

Residents in the Whitby proposal fear that British Gas, the utility which is working with Cadent to carry out gas safety checks ahead of the trial, will ultimately use the new powers to forcibly cut off the gas supply for residents who are opting out of using hydrogen.

As Cadent plans to transport hydrogen for the trial in its existing natural gas network, there is no option for homeowners to continue using natural gas for cooking or heating — they are instead being offered electric alternatives if they don’t want to use H2.

Locals are suspicious of Cadent’s lobbying efforts with the government, with a 700-strong Facebook group warning that policy is being made without their best interests at heart.

“We've got residents terrified that this change in legislation is going to let British Gas just force entry into their homes,” Kate Grannell, a Whitby resident and author of a petition against the Whitby trial, told Hydrogen Insight.

Grannell’s petition claims that the legislation will allow British Gas to enter a property and carry out works to discontinue supply.

But Cadent Gas denies that the powers will be used in this way.

“This is not true,” a spokesperson for the company told Hydrogen Insight. “British Gas are our partner in this trial and are currently carrying out gas safety checks on each property in the area to ensure they are safe and would be suitable for hydrogen. From the safety checks so far, we have fixed or replaced any faulty gas appliances free of any charge.”

However the draft legislation does appear to imply that the powers could be used in this way, in the name of safety.

“The Bill will enable the effective and safe delivery of a hydrogen heat grid conversion trial... by extending gas distribution network operators’ (GDNs) existing powers of entry to ensure that consumers in the trial area can be safely connected to hydrogen instead of natural gas, and to cover the full range of in-home alterations which may be needed to conduct a hydrogen trial, such as replacing appliances and installing and testing safety valves,” reads the UK government’s factsheet on the Energy Security Bill.

The increased powers of entry are “necessary legislative changes to facilitate the village trial”, it says, and would only be used as a last resort. This would apply to situations where customer safety would be at risk, and where all other methods of agreement with the property owner have been exhausted.

The gas supplier would also be required to secure a warrant from a judge.

“If the programme goes ahead in the area, there will be a need to make sure that every property in the area has a safe working heating and cooking appliance,” Cadent’s spokesperson told Hydrogen Insight.

Safety concerns

Gas suppliers already have powers of entry under UK law, in the event of an emergency, to carry out safety work — such as fixing a leak — or with a warrant, for example to disconnect a customer who is in arrears with their gas bill.

The new bill appears to extend these powers laterally, to include users who are part of the hydrogen trial but neither in arrears nor with any inherent safety issues with their natural-gas supply.

The safety risks would occur if the methane in the pipeline was replaced with hydrogen, but homeowners located in the trial area had either opted out of the hydrogen supply without agreeing to be disconnected from the gas network or tried to use the hydrogen supply in their existing appliances, one heating engineer told Hydrogen Insight.

A non-hydrogen-ready methane boiler would not have the right oxygen flow rate to burn hydrogen efficiently, leading to appliance degradation and a risk of unburned fuel leaking into the home, increasing the chances of an explosion. And typical gas cooking appliances would suffer a similar fate if used with hydrogen.

Even if residents opted not to use hydrogen but the supply was still connected, there is a risk that it could leak out of the pipes, especially from appliances that are not designed to carry H2 molecules.
Hydrogen is also 33 times more powerful a greenhouse gas than CO2 over a 20-year period, according to a recent UK government study.

The gas company is unlikely to be able to shut off supply from outside the property, and would need to close the valve located next to the gas meter, which is usually located either just outside or inside the building, the engineer said.

The Department of Business, Enterprise and Industrial Strategy (BEIS), which is sponsoring the bill, had not responded to questions from Hydrogen Insight at the time of publication, but emphasised in its fact sheet that the powers would not be used to force customers to use hydrogen.
