Netherlands to mandate hybrid heat pumps for boiler replacements from 2029

Mandate and technical scope

Dutch Housing Minister Elanor Boekholt-O'Sullivan submitted a letter to parliament outlining a mandate for hybrid heat pumps starting in 2029. Under the proposal, homeowners replacing an end-of-life central heating boiler must install at least a hybrid heat pump rather than a standard gas boiler. The policy does not require the premature replacement of functioning boilers, meaning existing units may remain in operation until they fail. The systems must incorporate smart controls that throttle power usage during peak grid hours and switch to natural gas when electricity demand peaks. Government data indicates that hybrid heat pumps reduce household gas consumption by roughly 65 percent, using approximately two kilowatt-hours of electricity to replace one cubic metre of natural gas.

Policy timeline and legislative process

The proposal revives a policy framework first introduced in 2022 by former minister Hugo de Jonge, which envisioned a mandate beginning in 2026. The previous cabinet led by Prime Minister Dick Schoof struck the measure from its programme due to concerns over high household costs. Following coalition negotiations between D66, the VVD, and the CDA earlier this year, the mandate returned as a central step toward eliminating natural gas heating across all Dutch buildings by 2050. The Tweede Kamer is scheduled to debate the letter next week, with final legislation expected after the summer of 2027.

Costs, loans, and exemptions

A hybrid heat pump typically costs between 6,000 and 8,000 euros, presenting a substantial financial hurdle for property owners. To ease adoption, the government relies on subsidies from the Netherlands Enterprise Agency (RVO) that cover approximately one-third of total purchase and installation costs. Property owners with a combined household income of up to 60,000 euros can also secure interest-free loans through the National Heat Fund (Warmtefonds).

This is why I am announcing it now, so you know that when your boiler needs replacing there is an expense item and you can take it into account.

The regulation will exempt apartments, historic monuments, and properties slated for connection to municipal heating networks, as spatial constraints and permit requirements complicate heat pump installation.

Industry capacity and workforce challenges

Heating equipment manufacturers and trade bodies responded favorably to the renewed timeline while pointing to logistical bottlenecks in the installation trade. Nefit Bosch and Remeha confirmed that European production lines can satisfy market demand, but warned of an acute shortfall of skilled fitters. A conventional boiler replacement typically takes half a day, whereas fitting and configuring a hybrid heat pump requires one to two full days of labor. Techniek Nederland chairman Mark Harbers stressed that political parties must avoid further policy reversals after the 2022 cancellation disrupted previous workforce training investments.

A clear standard gives consumers, installers, and manufacturers certainty and can accelerate the sustainability of existing homes.

Industry groups have urged the cabinet to freeze all regulatory details at least one year before the 2029 implementation date to provide stability for suppliers and homeowners.
