What is CLRD
The compliance infrastructure layer for the UK renewable industry.
The DNO submission is the part of an install most likely to come back wrong. CLRD turns it into one standard workflow, the same for a sole trader as for a national framework. It was designed by an installer who submitted these packs himself and built by engineers, not adapted from generic admin software.
- All six GB DNO groups and virtually all IDNOs. Every form. G98 or G99 including Fast Track, with G100 attached where export limiting applies.
- Submission ready DNO application packs in under three minutes, generated end to end.
- Solar, battery, EV charge points and heat pumps, alone or combined on one job.
- Every job audit ready by default, no extra effort, no extra software.

How it works
Enter the job once. CLRD routes it, builds it, submits it and closes it out.
The same workflow every time, whether it's a single residential install or a national framework delivering hundreds of dwellings a month.
- 01
Create job
Address, customer, MPAN. CLRD resolves the DNO, or your CRM creates the job over the API.
- 02
Enter the job details
Phase, kW, batteries, EV chargers, heat pumps, export limits, pulled from the ENA registers.
- 03
CLRD routes it deterministically
Routes to the right DNO and form from the ENA thresholds coded into the engine, then tells you why.
- 04
Add the evidence, generate the pack
Install date, configurable SLD, cut-out photo, boundary map and signatures. Then the pack.
- 05
Review and submit
Sent straight from the platform, with replies from every DNO landing in the same place.
- 06
Commission and close out
Post install forms and the real commissioning checklist, signed by whoever carried out the work.
Deterministic by design
The same job, submitted the same way, every time.
CLRD doesn't guess. Routing, equipment selection, SLD layout and supporting paperwork are produced by rules, not by people remembering on a Friday afternoon. Misrouted forms and rejected submissions, the slow tax on every installer, simply stop happening.
Zero misrouted forms, whatever the route
Zero hand drawn SLD inconsistencies
DNO ready, standardised every time
Every submission, fully audit trailed
Manual routing decisions per job
0by design
The route, the forms and the diagram are derived from the job data and the published rules. Nothing depends on who ran the job or what they remembered.

What powers the DNO application pack.
Every pack is built the same way, from DNO routing and an SLD to ENA references and submission, whether the job is solar, battery, an EV charger or a heat pump.

A breath of fresh air.
CLRD is a breath of fresh air in an industry known for being paperwork heavy. I'm really happy with how much it's streamlined my processes, especially the boundary line and SLD features. Great product, and I'm looking forward to the features coming next. 10/10!

“The multi technology submissions such as ASHP, solar and EV are so much easier now with CLRD. It works out the load and generation and totals, then routes via ENA thresholds in seconds, producing the right result every time. So far we have had first time approvals on our submissions with SSEN.”

One platform. Every scale of operator.
The same compliance workflow runs end to end, whether you're submitting one job a month or thousands across multiple regions and brands.
By the numbers
The mistakes a deterministic pack removes.

700
Pages of ENA framework, handled for you
G98, G99 and G100 run to around 700 pages and keep changing. CLRD keeps its routing tied to the current rules, so you don't have to read any of it.
12,000+
ENA registered devices in the platform
Around 9,000 inverters and export limiters, plus around 3,200 EV charge points and heat pumps. Reconciled against the published ENA registers at least monthly.
100%
Audit trail, by default
Every job, every decision, every output logged. Funder, warranty and framework evidence on demand.
