View official SEAI page →What you have to do to qualify
This is the only heating grant available if you are keeping a gas or oil boiler. SEAI will not grant-aid a new or replacement fossil fuel boiler.
- The home needs an MPRN and must have been built and occupied before 2011.
- It upgrades the controls on your existing system. It is not the heat pump grant, which replaces the system entirely.
- You can claim it with or without installing a high-efficiency boiler.
- You must have grant approval before the work starts, and a post-works BER afterwards. The full process, with every deadline.
Every rule above is SEAI's, read from their heating controls upgrade page on 17 August 2026. SEAI is the authority; where they and this page differ, they are right.
What the work costs
A heating controls upgrade costs a median of €3,500 for a detached house, according to SEAI's own figures. After this grant, that leaves about €2,800 to pay.
You pay that in full first. SEAI refunds the grant 4 to 6 weeks after the paperwork, so the money has to be available up front unless you borrow it or use a One Stop Shop. The three ways to pay.

Common questions
How much is the SEAI Heating Controls Upgrade grant?
The SEAI Heating Controls Upgrade grant is worth up to €700. The exact amount depends on your property type and the work carried out.
Who qualifies for the Heating Controls Upgrade grant?
Available for homes built and occupied before 2011. Must include time and temperature controls.
Do I have to use an SEAI registered contractor?
Yes. SEAI grants are only paid when the work is carried out by a contractor on the SEAI register. 670 registered contractors on Qualified.ie do this type of work, across 26 counties.
Can I claim more than one SEAI grant?
Yes. You can apply for several measures at once, and some measures require others first. The checker adds up only what this house is actually eligible for, which is not the same as the list of grants that exist.
When do I actually get the heating controls upgrade grant money?
On the individual grant route you pay the contractor in full and SEAI refunds you 4 to 6 weeks after you submit correct paperwork, including a post-works BER. So you need the money available first. The alternatives are the state-backed Home Energy Upgrade Loan, or a One Stop Shop, which deducts the grant from the price before billing you but costs more overall.
Do I have to apply before the heating controls upgrade work starts?
Yes, and this is the rule that most often costs people the grant. SEAI will not pay for work carried out before you have grant approval, and there is no retrospective application. Once the offer arrives you have 30 days to accept it and eight months to finish the works, get the post-works BER and return the paperwork.
What else does my home need to qualify for the heating controls upgrade grant?
This is the only heating grant available if you are keeping a gas or oil boiler. SEAI will not grant-aid a new or replacement fossil fuel boiler. Beyond that, the home must have an MPRN and have been built and occupied before 2011.
