RTS switch-off in July will put vulnerable Scots at risk
Good evening! This week's edition of the In Common newsletter comes from Dr Ron Mould, net carbon manager at Bield Housing.
AFTER 14 years of missed deadlines and shifting timetables, we've now entered the final month before the nationwide switch-off of the radio tele-switch (RTS) signal and the reality is looking increasingly grim.
With tens of thousands of homes still awaiting smart meter installation, we are now in a desperate scramble to avoid a full-blown crisis.
This is no small problem.
An estimated 30% of the UK's remaining RTS meters are in Scotland, disproportionately affecting rural, elderly, and vulnerable households. The consequences of failure are significant and at this late stage, feel inevitable.
As Net Carbon Manager at Bield, a housing provider supporting older people across Scotland, I've seen first-hand how badly this transition has been handled.
Our tenants are among those directly affected, people who rely on electric storage heating and trusted the RTS system to manage their energy needs affordably and safely.
Many are now facing anxiety, confusion and rising costs, with little to no support from the systems meant to protect them. Across the country, residents reliant on RTS for their heating are experiencing a barrage of issues, repeatedly aborted meter installations, often with no communication or learning applied to subsequent attempts.

Some can't even get appointments, with suppliers routinely stating there are 'no engineers available in your area.'
Even when installations do go ahead, the problems don't stop. New meters can trip electrics, prompting a game of finger-pointing between energy suppliers and electricians.
More commonly, the issue lies in the specification of the new meters themselves. Despite supplier claims of a like-for-like swap, many smart meters provide a continuous 24-hour supply, in contrast to the timed circuits of RTS systems.
Without integrated timers for heaters and hot water (previously controlled by the RTS signal) householders are left with systems that run around the clock, racking up unnecessary costs. Timers, if installed at all, often don't align with off-peak periods, which themselves have been allowed to erode, some tariffs now offer just a 1p difference between peak and off-peak.
The BBC's longwave broadcasting equipment, which transmits the RTS signal, has genuinely reached the end of its life. But while the technology may be out of date, the strategy to replace it is even worse. Ofgem has not delivered a clearly communicated, nationally coordinated plan. Instead of a well-managed transition, we've had vague reassurances and rumours of a phased switch-off—starting with regions that have the fewest RTS meters remaining.

Ofgem's own position is not especially reassuring: they admit they 'don't know what will happen.'
Whether we experience a complete signal loss or a cascading failure across zones, one thing is certain- there will be no further UK-wide delays. Even a phased switch-off is expected to take place over just a few months, with no guarantee of any extension for Scotland.
This is the sort of groundwork that should have been laid months ago, not weeks before the switch-off. Ad campaigns fronted by Lorraine Kelly have only recently hit the airwaves- despite repeated warnings that the RTS switch-off would create confusion and difficulty if not properly addressed early on.
These last-minute efforts, while welcome, reflect a broader lack of long-term planning.
At Bield, we're doing all we can to support our tenants — helping them navigate bookings, installations, and even explaining why their heating now works differently. But the scale of the issue is bigger than any one organisation can solve alone.
We're seeing the real-world consequences for those left in limbo by unclear processes and mixed messaging. For those with electric heating, I urge you to contact your energy supplier immediately and request a smart meter. If you've already had a failed visit, rebook — and keep rebooking until the job is done.
If you already have a smart meter, check that your hot water and heating systems have timers. Confirm they match your tariff's off-peak hours. If they don't, you'll need to adjust or retrofit them—otherwise, the promised cost savings will be lost.
The RTS switch-off is no longer a future event — it's here. The headlines this July are, sadly, predictable.
A lack of coordination, planning, and urgency from energy suppliers and regulators alike has led us to the brink of a national energy blunder.
And as someone working closely with the people now facing the fallout, I can say this with confidence: Scotland deserves better.
