Heat pumps & grants · Homeowner answer

What is an SEAI Technical Assessment?

Short answer

It is an assessment of whether your home is efficient enough for a heat pump to work well. SEAI requires one for the heat pump grant on homes built before 2007, unless a valid BER already shows a Heat Loss Indicator of 2.3 or lower. SEAI contributes €200 towards the cost.

What changes the answer

  • year of construction
  • existing BER and its Heat Loss Indicator
  • insulation already done

What you can check yourself

  • look up your BER certificate and its Heat Loss Indicator

What to do next

If the assessment says the house needs work first, do that work before the heat pump — it makes the heat pump smaller and cheaper to run.

Can a heat pump work with my existing radiators?

Often, yes. A heat pump runs at a lower water temperature than a boiler, so each radiator gives out less heat. Rooms where the radiator is generously sized usually keep theirs; smaller radiators in colder rooms may need to be swapped for larger ones. SEAI grant support covers up to €2,000 of central heating upgrades like this.

Heat pump or a new oil boiler?

If the house is reasonably well insulated, a heat pump is usually worth pricing alongside a new oil boiler: there is a substantial SEAI grant for heat pumps and none for a like-for-like oil boiler, and running costs are often lower. If the house is poorly insulated and you cannot do the fabric upgrades yet, a new oil boiler can still be the sensible choice for now.

How do SEAI heat pump grants work?

You apply to SEAI and get approval before work starts, an SEAI registered contractor does the work, a BER is done afterwards, and SEAI pays the grant. As at October 2026 the maximum is €14,500 for houses and €11,500 for apartments.
