For commercial solar & BESS developers 50kW – 5MW

Know if your site is worth pursuing — before you commit to the application.

Most commercial solar projects die at the DNO, not at the planner. Headroom screens your site against real grid capacity, queue position and curtailment risk in under 60 seconds — so you can put capital where it actually clears.

Grid Check

Postcode + target capacity. We do the rest.

Site postcode

Target capacity (kW)

Asset type

Live geocoding + DNO mapping + ECR comparable engine enabled. Site location, DNO assignment, constraint-zone links, and connection-fee comparables are pulled from live UK postcode data and DNO Embedded Capacity Registers. Headroom/queue/curtailment values currently use regional constraint models — production v2 layers in live LIFO queue feeds and refreshes ECR quarterly. All sourced figures link to the underlying DNO portal.
