Which accreditations should I insist on for a domestic install?

NICEIC, NAPIT or Stroma registration for Part P, the 18th Edition qualification with the 2921-31 EV unit and OZEV authorised-installer status if the customer is claiming the grant.

When is a DNO connection agreement (G99) required instead of a G100 notification?

Roughly, single-phase 7kW domestic installs fall under G100 notification. Anything three-phase, 22kW+ or with total site generation and load above the DNO threshold usually needs a full G99 connection application.

Do public chargers need PAS 1899?

Yes. Since 2022, public-access chargepoints in the UK are expected to meet the PAS 1899:2022 accessibility specification. Ask the installer for a compliance statement in writing.

What insurance level is normal for a commercial EV installer?

Most main contractors expect £5m to £10m public liability, £10m employers' liability and £1m+ professional indemnity where the installer designed the load and cable strategy.

Can Credbase track all this per installer?

Yes. Send the checklist as a request in Credbase and the installer uploads each item to a shared workspace. You get expiry reminders on every certificate and a live view of who is job-ready.

EV installer document checklist

Build the exact document, accreditation and insurance list to collect from an EV charger installer before they touch the wall. Pick the charger and site type, then copy or download.

Who this is for

Facilities and estates managers commissioning EV chargepoints
Fleet and sustainability leads onboarding installers at scale
Property developers and main contractors specifying EV works

Problem it solves

EV installs need a specific bundle of MCS-adjacent, NICEIC, OZEV and DNO paperwork that is easy to forget until commissioning day. This builds the job-specific list in seconds.

How it works

Step 1
Set the install
Pick charger type and site, then flag OZEV grant claims or groundworks if either applies.
Step 2
Tick what you have
Work down the generated list. Anything unticked is what you still need before the install goes ahead.
Step 3
Send or file it
Copy the list into an email to the installer, or turn it into a live request in Credbase.

Questions and answers

Where this tool stops

The checklist is minutes. Chasing MCS, NICEIC and DNO paperwork is weeks.

Knowing an installer needs MCS, NICEIC, OZEV approval and a DNO notification is one thing. Actually getting each certificate, checking it is current and filing it against the job is where installs slip.

Credbase turns the list into a live request per installer, reads each certificate on upload and flags expiries before the next job starts.
