Overview
- Landlords must retrofit or replace non‑remote heating and hot‑water meters by December 31, 2026, before the rules take full effect on January 1, 2027.
- Once remote devices are in place, tenants receive monthly consumption data in kilowatt-hours with comparisons to the prior month, the same month a year earlier, and average users, delivered via app, email or post.
- If required remote meters are missing after the deadline, tenants may cut the annual heating and hot‑water bill by 3%, with a further 3% reduction if monthly information duties are not met.
- The rules cover multi-dwelling buildings with central supply, now explicitly including heat pumps after an October 2024 change, while small two-unit owner-occupied buildings and homes without central heating are excluded.
- Acquisition costs generally fall to landlords, though rented devices can be passed on as operating costs, and only the landlord and their contracted service provider may collect and process the consumption data.
