Is this a replacement for my electrical certification scheme's own portal?
Certkit is the workspace for how your team captures visits, issues branded PDFs, and tracks renewals. It does not replace membership, competence, or filing requirements with your scheme or insurer. You stay responsible for the accuracy of the inspection and the certificate you issue.
Can engineers work underground / in plant rooms?
Yes. The field runner queues answers locally when there is no signal and syncs when reception returns. The office can see that work is pending instead of assuming it never happened.
Do we have to use Certkit for every service type?
No. Use it for electrical and PAT only, or run gas, fire, and water in the same workspace when you are ready. The product is one stack, not a bundle you have to switch on all at once.
