How a supposedly simple disconnection exposed the buried complexity of electrifying homes.
I thought my home had left gas behind when the meter was removed. More than a year later, I discovered that becoming gas-free on paper and becoming physically disconnected from the gas network are two very different things.
When I wrote about the end of our renovation, I described it as the close of an 18-month journey. That was optimistic. A house, it turns out, is never really finished and neither is its energy transition.
Our move away from gas had felt complete for some time. We replaced the old boiler with an air source heat pump, upgraded the electricity connection and gradually learned how to run an all-electric home. I covered much of that in my earlier post on the heat pump. Last week, however, the gas network returned for what I assumed would be a small piece of unfinished business. It became a rather vivid lesson in what the energy transition looks like below ground.
The meter had gone, but the pipe had not
I had never used gas since buying the house, but for a while I still paid the daily standing charge. I also received erroneous bills for gas consumption because a previous supplier did not believe the smart-meter readings, which were consistently, and correctly, showing zero. There are few things more absurd than being asked to prove repeatedly that you have not consumed a fuel you do not use.
More than a year ago, I arranged through my energy supplier for the gas meter to be removed. It felt like a significant milestone. The standing charge stopped, the phantom consumption should have disappeared and the most visible piece of gas infrastructure had left the house.
Then a letter arrived from the gas distribution network operator. It said that, although the pipe inside the house had been capped, the service remained connected to the live main. On health and safety grounds, the network operator wanted to disconnect it at the source. It would also remove any theoretical temptation to embark on a second career stealing gas!! An implausible business model.
A simple plan
The process initially seemed clear. An engineer visited, inspected the capped connection in the house and planned the work. An engineering team would then return, excavate the service pipe where it joined the main, disconnect it and reinstate the ground.
The team arrived with a permit to dig up the verge. Their geographic information system, GIS, showed a six-inch gas main running beneath it. They dug down. There was no main.
They then tried to trace my service pipe. That was also difficult because signals from the other utilities buried in the street created too much interference. Eventually, the team found an old metal gas pipe running in the direction of my house. It appeared to be the one they needed.
They cut and capped it and then found gas still coming from the end nearest my house. The realisation followed quickly: the pipe they had interrupted was supplying my neighbour on the opposite side of the road.
The neighbour, the larger main and several more holes
This was understandably not the outcome my neighbour had expected from my decision to stop using gas. It also confused the engineering team. There is a ten-inch gas main on my neighbour’s side of the road, so the natural assumption was that the house would be connected to that. Instead, an old metal service took a less obvious route across the street.
The job now had to be replanned. The team needed to create a new connection for the neighbour, continue the search for the main serving my side and obtain an additional permit to excavate the pavement. A few days later, everything was put right. My neighbour had a new polyethylene, or PE, service connection, my old service was finally disconnected correctly, and the long process of refilling and reinstating the many holes could begin.
It would be easy to tell this only as a story of a map being wrong or a job going awry. That would miss the more interesting point. The engineers encountered a network that had evolved over many decades, with old materials, unexpected routes, other utilities and incomplete information. Once the problem became clear, they made the situation safe, restored the neighbour’s supply and completed the disconnection. The episode was inconvenient, but it was also revealing.
Electrification is physical
At household level, electrification can sound deceptively simple: install a heat pump, change the cooker, remove the meter and stop buying gas. Those are the decisions we see. Beneath them sits a shared physical system of pipes, cables, valves, records, permits, contractors, pavements and neighbours.
My home did not leave the gas network through a single transaction. It involved my supplier, the gas network operator, survey work, tracing equipment, excavation permits, an engineering crew, a temporary interruption to another customer, a replacement service and street reinstatement. None of that changes the case for electrification. It does show that the transition has a delivery cost and a coordination challenge that are easy to omit from national models.
The Government Office for Science has described the subsurface as an increasingly contested space, with the electrification of heat and transport requiring more underground electricity infrastructure while legacy fossil-fuel assets may need to be decommissioned or repurposed. My verge was a very small example of that wider problem: the map was neat; the ground was not.
Who plans and who pays for the last gas pipe?
The question becomes more important as more homes move away from gas. Ofgem has already recognised that the current domestic disconnection process can be costly, difficult to navigate and a potential barrier to electrification. Its review of the gas disconnections framework starts from an important principle: consumers need a practical way to exercise the choice to leave the gas network.
But an orderly transition cannot be designed one household at a time. The Department for Energy Security and Net Zero has identified the need to maintain a safe and resilient gas system while its role changes, manage investment and affordability as the customer base declines, and plan the repurposing or decommissioning of assets that are no longer needed. Its update on the future gas system is a reminder that this is not just a technology choice. It is also a sequencing, regulation and cost-allocation problem.
If disconnections grow, we will need to answer some practical questions. When is it better to plan street by street rather than house by house? How can old network records be improved and checked before digging begins? Can gas, electricity, water and fibre works be coordinated so the same pavement is not opened repeatedly? Who should meet the cost of removing redundant connections: the departing customer, remaining gas users, taxpayers or the wider energy system? And how do we make sure a choice made by one household does not create an avoidable risk or disruption for the people next door?
A small ending, and a bigger beginning
My house is now not only gas-free in the way it operates and the bills it receives; it is physically disconnected from the main. That is a satisfying final step in the renovation story. It also leaves me with a stronger appreciation of the people who have to turn policy ambition into safe work in real streets. The gas engineers were great.
In the final post of my original renovation series, I wrote that systemic hurdles stood between an efficient home and wider adoption. This experience adds another hurdle to the list, but also makes it more tangible. Net zero will be built through heat pumps, solar panels and smarter electricity use. It will also be built through accurate records, well-planned street works, fair cost recovery and thousands of careful decisions about old pipes no longer required.
The energy transition is often described in gigawatts, carbon budgets and national targets. Sometimes it is better understood through one missing gas main, one unexpectedly connected neighbour and rather more holes in the ground than anyone planned.
