Available Support for Homeowners

The Northern Ireland grant environment offers support to homeowners looking to make their homes warmer, more energy-efficient and more affordable to run.

Whether you’re looking for insulation, heating system upgrades or broader home energy improvements, there are schemes available.

We at BlueBuild Energy guide you through the process—from initial assessment, understanding eligibility, to application and installation.

Affordable Warmth Scheme

Support for households on lower income to improve energy efficiency.

The Affordable Warmth Scheme is a grant-aid initiative focused on helping owner-occupiers and certain private tenants whose income is below a specified threshold.

Typical Measures Covered:

  • Loft/attic insulation
  • Cavity-wall insulation (where suitable)
  • Draught-proofing and lagging
  • Replacement of inefficient heating systems (subject to scheme rules)

Eligibility Criteria:

You must live in and own (or rent privately with qualifying conditions) the home as your main residence.
Household gross income must be below approximately £23,000 (check latest threshold) in many cases.
The property must not be a holiday home, B&B, or commercial establishment.

NISEP – Northern Ireland Sustainable Energy Programme

Energy-efficiency funding for domestic homes across Northern Ireland.

The Northern Ireland Sustainable Energy Programme (NISEP) is a nationally-administered fund, collected via a levy on electricity customers, that supports a range of energy-efficiency programmes for households and businesses.

What the Scheme Offers:

  • Fully-funded or part-funded measures like loft insulation, cavity wall insulation, draught-proofing, hot water tank jackets, LED lighting, smart heating controls. 
  • Priority is given to vulnerable households (at least 80% of funding) but non-priority schemes are also available.

Am I Eligible for NISEP?

My home is located in Northern Ireland and is a residential dwelling.
I am the homeowner, or a private tenant in schemes where tenancy is allowed.
I am a low-income or vulnerable household, or my home qualifies for a non-priority scheme.
The proposed measures are listed as eligible under the NISEP sub-scheme (insulation, draught-proofing, heating, lighting, smart controls).
My property is not new build or under major structural extension.
I understand that funding is subject to availability and allocated on a first-come, first-served basis.
I am aware that restrictions may apply based on heating type or fuel availability (e.g., off-gas areas).

Frequently Asked Questions

Yes — often you can upgrade more than one part of your home (insulation + heating system) but eligibility depends on the individual scheme.

There is less clarity around solar-specific grants for NI homeowners compared with the Republic; check local council or NISEP-supported schemes.

You may find local financing, or the ability to spread upgrade costs, but always check the terms and eligibility.
