Overview
- Existing non-remote devices must be retrofitted or replaced by 31 December 2026, with remote-readable metering mandatory from 1 January 2027.
- Once digital meters are installed, landlords must deliver monthly consumption reports showing kilowatt-hours plus month-on-month, year-on-year, and comparable-household benchmarks.
- Noncompliance can be penalized with a 3% reduction to the annual heating and hot-water bill for missing retrofits, plus an additional 3% if monthly information duties are not fulfilled.
- The framework applies to multi-occupancy buildings with central heating or hot water, excluding owner-occupied two-unit homes and dwellings without central systems; heat-pump systems are explicitly included after a 2024 change.
- Landlords generally bear purchase costs for new meters, though rental or service contracts may pass ongoing charges through operating costs, and devices must offer smart‑meter‑gateway capability without requiring its active use.
