Know if a site is worth pursuing in 30 seconds — before spending money on surveys, legal, or design. Live DNO data, real substation headroom, ECR queue.
The document pack knows your site. Postcode, DNO, capacity, technology, connection voltage — all pre-filled. You complete the gaps, print, and submit.
Every application outcome we track (predicted vs actual) makes the screening more accurate. The more you use it, the better the verdict for your DNO area.
The live screening engine currently uses UK Power Networks (UKPN) capacity heatmap and ECR data, covering South East England, East of England and London. This covers a large proportion of UK commercial solar pipeline. Expansion to NGED, Northern Powergrid, ENWL, SPEN and SSEN is on the roadmap. The document pack works for all six DNOs — it uses the ENA standardised forms (SAF, Form A1-1 etc.) which all DNOs accept.
No — the document pack generates forms that are ready to review, complete, and submit. You (or your installer/agent) submit to the DNO through their portal, ENA Connect Direct, or by email as directed. Headroom does not submit on your behalf in the current version. Managed submission is planned for the Agency tier.
Yes. The protection settings defaults in the Protection Settings Schedule reflect ENA EREC G99 Issue 2 (10 March 2025), including the removal of Vector Shift as a standalone LOM method and the updated RoCoF settings. The SAF template reflects SAF v11.14 (June 2025). If you're unsure which version your DNO is currently accepting, check their website — some DNOs are still transitioning to Issue 2.
The Full Platform (£149/mo) is built for you — both domestic (G98/G99 Type A) and commercial (G99 Type B) screening and document packs in one subscription. At £149/month, you'd break even against G59 bureau fees after a single domestic application.
The Agency tier is designed for application bureaux, large developers with teams, and installers managing multiple client accounts. It adds multi-user logins, a client management dashboard, bulk CSV site import, and API access. It is in development — register interest and we'll notify you when it launches.
