Indicative Funding / Grant Range & Net Cost

Payback Analysis

⚠️ Indicative screening result only β€” based on profile and benchmark inputs, not site measurements, formal BER assessment, or engineering design. Cost bands use broad benchmark assumptions and should be treated as early screening ranges only. Excludes VAT, professional fees, and tenant disruption costs. Illustrative payback only β€” excludes financing, occupancy disruption, maintenance, and specific site conditions. Grant eligibility, scheme rules, and funding availability change frequently β€” verify directly with SEAI before relying on any grant range in financial modelling. All outputs should be verified by a qualified MEP engineer and quantity surveyor before use in any decision-making process.
