- From 1 September 2027, new fixed-term energy contracts for designated non-domestic premises must require the customer to have or accept a smart or advanced meter.
- The final policy is narrower and later than initially proposed, giving suppliers and businesses more time to prepare.
- Better consumption data could support flexibility and half-hourly settlement, but the policy’s value depends on meters working reliably and businesses retaining access to competitive contracts.
Energy suppliers will have to make smart meter acceptance a term of new fixed-term contracts offered to smaller non-domestic sites from September 2027, under the UK government’s post-2025 rollout framework.
The rule will apply initially to “designated premises” in England, Scotland and Wales. These are generally smaller sites with electricity meters in profile classes one to four or annual gas consumption below 732MWh.
Suppliers will not be required to ensure that a meter is physically installed before the contract begins. They must include a term stating that the customer already has, or agrees to have, a smart or advanced meter.
A communication obligation will begin on 1 January 2027, requiring suppliers to explain the forthcoming change, its purpose and the action customers may need to take. Suppliers must comply fully with a legally binding consumer protection code by 1 September.
The final policy has been narrowed and delayed following a consultation that received 46 responses. The original proposal envisaged implementation from January 2027 and was framed more broadly across the non-domestic market.
The government response limits the first phase to small and medium sites and provides an additional eight months for systems, contracts and customer communications to be prepared.
Usable flexibility
Smart meters are a basic component of a more flexible electricity system. They replace estimated readings with granular consumption data, allowing suppliers to improve forecasting and giving businesses a clearer view of when they use energy.
That information can support time-of-use tariffs, battery optimisation, demand reduction and market-wide half-hourly settlement. It should also reduce manual meter-reading costs and some billing disputes.
The government’s earlier analytical work estimated that intervention could lift non-domestic smart coverage to 88% by 2030, compared with 73% if deployment relied only on new and replacement meters. Those figures preceded the final decision to narrow and delay the measure, so the eventual rollout trajectory may be lower.
The policy addresses a collective action problem among suppliers. Some companies already offer smart-contingent contracts but may hesitate to enforce the terms if customers can switch to rivals that do not. A uniform start date removes much of that competitive disadvantage.
Industry and consumer groups nevertheless identified practical risks. Energy UK warned that the original framework could impose significant administrative costs and did not fully resolve obstacles such as expensive remedial work or meter-operator arrangements outside suppliers’ control.
Citizens Advice supported higher uptake but warned that “mandating smart meters for all small businesses could generate a backlash”. It also raised the risk that tenants could lose access to attractive tariffs if landlords refused installation. The organisation’s consultation response called for stronger landlord engagement and regulatory oversight of meters that stop communicating.
Installation alone does not create a smart energy system. Government data published in March showed that 8.3% of smart and advanced meters were operating in traditional mode at the end of September 2025. A non-communicating meter cannot provide the data services on which the policy’s claimed benefits depend.
The consumer code is therefore central. It requires fair and proportionate enforcement, protections around appointments and consideration of financially vulnerable organisations. Separate guidance covers landlord and tenant cooperation.
For suppliers, brokers and energy managers, the operational deadline effectively begins in January, when communications become mandatory. Contract templates, installation processes and property consents will need reviewing well before September.
The larger opportunity is to convert more business demand into a flexible system resource. The danger is that the policy becomes another installation target without sufficient attention to functionality, data access and the commercial products that make smart consumption worthwhile.
