Explore how British Gas leverages smart meters, IoT, and AI to improve energy efficiency and customer experience, helping 5.3m households avoid price cap overcharges.
On Wednesday, the energy price cap rises by 13% to £1,862 per year for the average household, adding £221 to annual bills. Yet an estimated 5.3 million households on standard tariffs still lack smart meters, risking overcharges for June usage if they don't submit manual readings. British Gas's smart meter rollout is the direct solution: it eliminates the need for manual reads and ensures customers are billed at the correct rates during price cap transitions.
Customers who don’t have a smart meter should submit their readings before or on Wednesday 1 July, so their supplier has an accurate view of their account, warned Ben Gallizzi, energy expert at Uswitch.
The gap highlights a persistent adoption challenge. Without real-time data, households face billing errors and miss opportunities to shift usage to cheaper off-peak periods. British Gas has installed over 8 million smart meters across the UK, but nearly a third of its standard tariff customers remain unconnected. The company is investing in targeted outreach and incentives to close this gap, emphasizing that smart meters are not just convenience—they are essential for accurate billing in volatile energy markets.
British Gas's smart home ecosystem extends beyond meters to connected thermostats, plugs, and appliances, all feeding into a unified platform. By integrating IoT devices, customers gain real-time consumption data and can remotely control heating and electronics via the British Gas app. This capability allows households to turn off standby devices, schedule heating around occupancy, and reduce waste without sacrificing comfort.
For example, a connected thermostat can learn daily routines and adjust temperatures automatically, cutting heating costs by up to 20%. Similarly, smart plugs let users monitor individual appliance energy use—identifying vampire devices that draw power when idle. British Gas reports that customers with IoT integrations save an average of £120 annually on energy bills, underscoring the financial and environmental benefits of real-time management.
The company is also piloting vehicle-to-grid (V2G) chargers that allow electric vehicle owners to sell excess battery power back to the grid during peak hours, further optimizing energy use. This IoT ecosystem positions British Gas as a holistic home energy partner, not just a supplier.
British Gas applies machine learning to smart meter data to generate personalized energy-saving recommendations. Algorithms analyze historical consumption, weather patterns, and occupancy to predict daily usage and suggest optimal times for high-energy activities like laundry or charging devices. These AI-driven insights help customers shift consumption to off-peak hours when rates are lower, reducing bills without behavioral sacrifice.
For instance, a household with a standard tariff might receive a notification: “Run your dishwasher after 9 PM to save £15 per month.” The system also flags anomalies—unexpected spikes that could indicate a faulty appliance or forgotten heater—and alerts the user. This proactive approach prevents surprise bills and promotes energy efficiency at scale. British Gas's AI platform currently processes over 1 billion data points daily, continuously refining its models to improve accuracy.
“AI personalization turns raw data into actionable savings,” says a British Gas spokesperson. “We want every customer to feel in control of their energy.” The company's digital assistant, available on the app, answers queries about billing, tariff changes, and energy-saving tips, reducing call center volume and improving customer experience.
