01
Rules, not guesses
Routing follows the published ENA framework, not a language model. The logic is explicit, and it is auditable.
Platform
The compliance engine behind every DNO pack.
CLRD is not a template library or a chatbot. It is a deterministic compliance engine for UK DNO applications: the same install data always produces the same route, the same SLD and the same audit ready pack. Here is how it is built, and why it holds up at audit.
The core idea
Deterministic, not generative.
CLRD is rules based, not AI guesswork. Every routing decision, every diagram and every reference is derived from your install data and the published DNO rules. No hallucinated values, no surprises in the pack.
02
Traceable to the input
Every decision traces back to the exact install detail that drove it. Nothing is invented along the way.
03
The same pack, every time
The same inputs always produce the same route, SLD and pack. That repeatability is what auditors and insurers trust.
Always current
Tied to 900 pages of regulation, so you're not.
The ENA framework (G98, G99, G100) runs to around 900 pages and keeps changing. CLRD keeps its routing and reference data tied to the regulations in force, so every output reflects the current version and stays defensible at audit.
ROUTING
G98, G99, G100 and Fast Track
Decided deterministically per job, from your install data.
EQUIPMENT
~6,700 FTT inverters
Every ENA registered Fully Type Tested inverter, single and three phase. Non FTT and mixed phase setups are not supported.
DNO COVERAGE
Every major UK DNO
UKPN, NGED, SSEN, NPg, ENWL and SPEN, plus nearly all IDNOs.
SCOPE
Domestic & small commercial
Up to 50 kW three phase or 17 kW single phase, with or without battery, and battery only.
The output
One artefact: a submission ready pack.
Everything the engine does produces one thing: a complete DNO pack for the job. The filled out G98, G99 or G100 forms, a generated single line diagram, a Letter of Authority for the customer to sign, and the commissioning forms and supporting documents. Submit it from the platform or download it at the press of a button.

EnlargeProvable
Every decision, provable at audit.
Compliance is only worth anything if you can prove it later. CLRD records the chain as you work, so the evidence is already there when someone asks.
01
Immutably hashed
Every meaningful change is recorded and hashed, so the record cannot be altered without trace.
02
Who, what, when
Each event captures who did it, when, and with which inputs and outputs.
03
One clean export
A project's full audit chain exports as one continuous report, ready when a DNO or auditor asks.
Your data
Yours, held in the UK, defensible.
01
UK cloud, encrypted
Held on UK based cloud infrastructure, encrypted in transit and at rest.
02
Role based access
People see the slice of the workspace their role allows, nothing more.
03
You own it
CLRD processes your data on your behalf in line with UK data protection law and ICO guidance. Export it any time.
