Commercial G99 DNO Applications, Managed End-to-End.
We prepare, submit and manage G99 applications across every UK DNO, handling technical queries and chasing progress through to a decision. From domestic systems to commercial and utility-scale projects.
More than a G99 submission.
Every application is reviewed by our team before submission. Once it's with the DNO, we manage the correspondence, chase progress and keep everything visible through your portal until a decision is received.
Prepared properly
Every project is reviewed by our team before submission. Protection settings, SLDs, capacity and G100 arrangements are all checked so the DNO doesn't send it straight back.
Submitted & managed
We submit directly to the relevant DNO, obtain the reference and manage the application throughout assessment.
Queries & chasing
We handle DNO correspondence, respond to technical queries and proactively follow up until a decision is returned.
Portal visibility
Applications, documents, messages and approvals in one place, visible to you and your team throughout.

Larger project? Get the connection strategy right first.
For larger commercial, solar farm, BESS and hybrid projects, the challenge often isn't completing the G99 form. It's determining what to apply for in the first place.
For projects over 1 MW or where available capacity is uncertain, speak to our grid connection team before submitting.
