Ofgem closed its investigation into Smart DCC’s procurement practices on 12 October, after Capita subsidiary CPI demonstrated tighter financial controls. The probe, opened in March 2023, examined whether CPI had breached licence conditions in its role as the central delivery body for Britain’s smart meter network.
As reported by Yahoo Finance UK, CPI will now be subject to enhanced monitoring for 18 months. But what does a regulatory investigation into a back-office contractor mean for the 33 million smart meters already installed in UK homes?
The cost of compliance, and who pays
Smart DCC’s budget is ultimately funded through energy bills. Every household with a smart meter contributes roughly £2.50 a year to cover DCC’s operating costs, according to Ofgem’s latest annual report. That figure could rise if CPI’s remediation programme runs over budget.
Ofgem’s statement notes that CPI has “strengthened its governance and control framework” and appointed a new compliance director. But the regulator also warned that any future breaches could trigger a full enforcement case. The catch is that past procurement failures, which the investigation did not quantify, may have already added hidden costs to the programme. The National Audit Office estimated in 2023 that the smart meter rollout had cost £13.5 billion, with benefits still falling short of original targets.
Who qualifies, and who doesn’t
For homeowners, the investigation’s closure changes nothing about your smart meter’s operation. Your in-home display will still show real-time energy use. Your supplier can still take remote readings. But the episode raises a broader question: is the smart meter infrastructure delivering value for money?
Energy Saving Trust data suggests households with smart meters save roughly 2–3% on electricity bills on average, primarily through better awareness of usage. That’s about £20 a year on a typical £1,200 dual-fuel bill. But the savings depend entirely on behaviour, not on DCC’s procurement controls.
What it costs a typical 3-bed semi
Let’s translate the regulatory language to your annual statement. Ofgem’s decision means no immediate fine for CPI, so no direct hit to bills from this investigation. But the wider smart meter programme has already added about £100 to the average household’s energy costs over the past decade, according to the NAO. Those costs are sunk. The question now is whether the enhanced monitoring will prevent future inefficiencies.
CPI must now submit quarterly compliance reports to Ofgem for 18 months. If those reports flag further problems, the regulator could reopen the case. Homeowners should watch for any future announcements about DCC’s budget, that’s the number that will eventually appear on your bill.
What this misses
Yet the investigation’s narrow focus on procurement misses a bigger issue: the smart meter network’s vulnerability to cyber-attack. In January 2023, a separate Ofgem report found that DCC had “significant work to do” on cybersecurity. The regulator has not published an update since. For households, a hacked smart meter could mean manipulated billing data or, in a worst-case scenario, remote disconnection. That risk remains unaddressed by the procurement probe’s closure.
Homeowners with smart meters should continue to monitor their in-home displays for unusual readings and report any discrepancies to their supplier. The system is safe for now, but the regulatory spotlight needs to shift from procurement contracts to network security.
Frequently Asked Questions
No immediate impact. Ofgem closed the case without fining CPI, so no direct cost to households. But past cost overruns in the smart meter programme have already added roughly £100 to the average bill over a decade, according to the National Audit Office.
The investigation focused on procurement, not cybersecurity. CPI has strengthened its controls, but Ofgem has not addressed broader network security risks. Report any unusual readings to your supplier.
