How long has each compliant kit been on the register?
Last verified: 2 September 2026 at 11:06 — read from the ENA type test register by us.
Why this page exists
A live list can tell you what is there today. Only a kept log can tell you how long it has been there. We have kept an append-only log since 5 August 2026 — 10 timestamped readings, of which 7 record every device individually. The counts below are measured from that log, not estimated.
Every number on this page is measured per manufacturer from its own first appearance, not from the start of the log. A manufacturer that first appeared on 28 August cannot have been present for seven readings.
Stability by manufacturer
| Manufacturer | Models listed compliant | First seen compliant | Our readings since then | Same set of models for |
|---|---|---|---|---|
| Perlight | 8 | 27 August 2026 at 19:19 | 5 | 4 |
| UKSOL Ltd | 7 | 19 August 2026 at 18:11 | 7 | 6 |
| InstaGroup | 2 | 28 August 2026 at 22:10 | 4 | 4 |
| Thunder Energy | 2 | 28 August 2026 at 22:10 | 4 | 4 |
| City Plumbing Supplies | 1 | 28 August 2026 at 22:10 | 4 | 4 |
“Same set of models for” counts backwards from 2 September 2026: the number of consecutive readings in which that manufacturer’s exact set of compliant references did not change. UKSOL shows seven readings but six unchanged because it went from four compliant models to seven on 26 August.
The list moves more than you would think
- Perlight replaced its entire first batch. Four Perlight references (PERLI/21112/V1, PERLI/21113/V1, PERLI/21114/V1 and PERLI/21116/V1) were in the list and gone by our reading of 27 August 2026. The eight PowerPlug models listed compliant today carry different references, first seen from 27 August.
- Entries come back under a new revision. City Plumbing’s kit appeared as CITYP/21096/V1/A3, left, and is on the list today as CITYP/21096/V1/A4. InstaGroup’s INS-PPG-800 has been through A2, A8 and A9 in our log. Anker’s ANKER/20920/V1 became ANKER/20920/V1/A2 on 31 August. A reference disappearing is not always a product disappearing.
- Seven manufacturers have entries in our log and none on the register today: FoxESS, GoodWe, HDMSO, Modular, Octopus Energy, Segen, TSUNESS.

The full log, with every device in every reading, is on our register change history page.
What this page does not mean
A device leaving the list is not evidence that it is a poor product. Entries move for reasons we cannot see from the outside: a revision, a withdrawal, an administrative change, a resubmission. We record what changed and when we saw it; we do not guess at reasons.
A long run on the list is not a recommendation either. It tells you the entry has been stable. It says nothing about how the kit performs, what it costs, or whether it suits your wall.
Compliant here is the register’s own assessment, that network operators will accept the equipment. It is not the same thing as certification to the Interim Product Specification v2, and we have not verified that any of these kits carries that certification.
We have not tested any of these products. This page counts entries in a public register; it is not a review.
