Northern Ireland Sustainable Energy Programme

On behalf of the Utility Regulator in Northern Ireland, Energy Saving Trust is the Programme Administrator of the Northern Ireland Sustainable Energy Programme (NISEP). This is an £8 million fund, collected from both domestic and commercial electricity customers through a public service obligation (PSO).

Households across Northern Ireland can benefit from the NISEP with funding being used for such energy efficiency schemes:  

• Boiler upgrade
• LED light bulbs
• Hot water tank jacket
• Water widget
• Remote smart heating controls
• Radiator panels
• Draught proofing
• Loft insulation
• Cavity wall insulation
• Solid wall insulation

The majority of the funding (80%) has been targeted at vulnerable customers. All schemes run on a financial year basis and there are currently 11 scheme managers delivering these schemes.

Following discussions with the Department for the Economy, NISEP will be extended from April 2025 to March 2027.
