Manna Grato is an independent cost consultancy focused on Commercial Assurance and Early-Stage Cost Certainty for Data Centre Power and Utilities.

We operate where CAPEX budgets are most exposed:
HV/MV Grid Interface, Grid Connections, Substations, HV/LV Distribution, Cable Routes, Enabling Civils and Sitewide Utilities, the scope that will quietly reshape a business case when assumptions are wrong.

Our fluency in this scope is grounded in MEP quantity surveying practice built across Network Rail Electrification, HS2 New Station Build and Fitout, and major infrastructure programmes.

What we do:
We bridge Data Centre delivery realities with DNO/IDNO and grid-side constraints, enabling Developers and Investors to make decisions based on credible budgets, realistic allowances and clear risk positions before complexity and change get locked in.

1. Commercial Assurance for Data Centre Power & Utilities
2. HV/MV Grid Interface Advisory (DNO/IDNO, Substations, Cable Routes, Enabling Civils)
