Compliance
The documents a British power-electronics programme is actually assessed against. Every designation and issue number here carries the source it came from and the date we checked it, because in this field a page written from older sources is not slightly stale — it is wrong.
- Public document
- You can open it and check us. We name the clause and quote it where it matters.
- Restricted document
- Real, named, and behind Defence Gateway SSO or a standards paywall. We cite the designation and issue; we do not reproduce text we cannot license.
Public documents

Do you still need UKCA in 2026?
No. CE marking is accepted in Great Britain indefinitely for the EMC and Low Voltage regimes, and there is no end date.

GB, the EU and Northern Ireland — three markets, one product

The MOD contract condition that flows down the whole supply chain, and the deadline attached to it.

Def Stan 05-138 and the four Cyber Risk Profile levels

What is deliberately not on this site
These were researched and could not be confirmed to a current source. Rather than publish a revision letter from memory, they are absent — and listed, so you can see the shape of the gap.
- · DO-160 / ED-14 current revision letter — NOT VERIFIED
- · MIL-STD-704 current revision — NOT VERIFIED
- · EN 50549-1 / -2 versions — NOT VERIFIED
- · BS 7671 current amendment number — NOT VERIFIED
- · The UK statutory 230 V supply tolerance under ESQCR 2002 — NOT VERIFIED
- · UK REACH deadlines — NOT VERIFIED
- · UKAS / ILAC mutual-recognition position — NOT VERIFIED
- · Whether GB's EMC designated-standards list has diverged from the EU's — checked, and the intuitive answer appears to be WRONG. Both lists look stalled at 2022. Do not publish a divergence claim.
- · INTEPRO UK'S CURRENT JOSCAR STATUS — the 2016 entry is documented in trade press, but JOSCAR requires annual renewal and the register is not public. We state the 2016 fact and nothing about today.
- · INTEPRO UK'S OWN CYBER RISK PROFILE LEVEL AND CYBER ESSENTIALS STATUS — a supplier's assigned CRP comes from the MOD delivery team per contract and is not ours to publish; our Cyber Essentials certification could not be confirmed on the IASME register.
