Applications for the deep retrofit pilot scheme submitted before the July deadline will be honoured, the Government has confirmed.
They're also pledging to develop a new retrofitting model to 'scale-up' efforts to achieve the goal to retrofit 500,000 homes, as set out in the recent climate action plan.
Earlier this month it was reported that funding had run out for the pilot scheme, which was aimed at supporting retrofits of older housing to improve their energy ratings.
The scheme - which ran for three years - allowed for 50% funding for upgrades to homes, with 95% funding provided for low-income households.
The Irish Times reported more than 300 homeowners who had been awaiting approval by the Sustainable Energy Authority of Ireland (SEAI) for the grant would not receive their funding.
Climate Action Minister Richard Bruton met with Jim Gannon, chief executive of the SEAI, this morning to discuss the situation.
Minister Bruton has now assured anyone who had submitted an application for the pilot scheme before the deadline will have their application "assessed and honoured in line with the existing terms and conditions of the scheme".
He said the focus must now be on moving to large-scale models rather than individual, small-scale initiatives.
He added: “The retrofitting of 500,000 homes, to make them warmer and more energy efficient, is a key action under the Climate Action Plan.
"Not only will these upgrades help us deliver on our climate commitments, but they will result in cleaner, healthier, warmer homes and will save homeowners money through cheaper energy bills.
“The new model will group home retrofits in the same area together to reduce costs, develop easy pay back mechanisms like through your electricity bill, and get access to new smart finance and loan options."
A taskforce is being set up to develop the new model, with a pilot in an urban and rural area to take place next year.
They'll also consider the possibility of 'easy pay' models, similar to the current bike to work scheme.
