How we calculate
Floor area (m²) × monthly use (kWh/m²) ÷ 1,000 = megawatt-hours (MWh). MWh × tariff incl. VAT = heating cost. Consumption figures come from the Riga Energy Agency’s data on buildings heated by Rīgas Siltums: on average 170 kWh/m² a year for heating in an unrenovated building and 77 kWh/m² after full renovation; energy class F means more than 125 kWh/m² a year.
Frequently asked questions
How much does heat cost in Riga from 1 December?
Rīgas Siltums charges €96.33 per MWh before VAT from 1 December 2026, or €107.89 including 12% VAT. Until 30 November the tariff is €80.96 before VAT (€90.68 with VAT). The new tariff takes effect unless the regulator, SPRK, revokes it.
How much more will I pay?
Each megawatt-hour costs €17.21 more including VAT (+19%). A flat that uses 1.5 MWh in December will pay about €25.81 more.
How accurate is the calculator?
It gives a rough figure. Your actual bill depends on the weather, the building’s insulation, how the heating system is balanced and how the building manager splits the building’s consumption between flats. Hot water is not included. The most accurate figure comes from your own bill: multiply the MWh used by the tariff.
How can I cut my heating bill?
Rīgas Siltums says turning the room temperature down by 1 °C saves up to 6% of the heat. Comprehensive renovation has the biggest effect: Riga Energy Agency data show a renovated building needs roughly half as much heat.
