Can I generate PDF certificates from CertBase?

Yes. CertBase generates professional, signed PDF test certificates automatically the moment a job is marked complete. Certificates can be shared with clients directly from the field.

How much does CertBase cost?

CertBase plans start from £19.99 per month. A 14-day free trial is available with no credit card required. Visit certbase.co.uk/pricing for full plan details.

Is CertBase suitable for PAT testing contractors?

Yes. CertBase is built specifically for PAT testing contractors and field teams. It supports multiple client sites, team assignments, retest scheduling, and bulk certificate generation.

Does CertBase support EICR testing?

Yes. CertBase includes an EICR (Electrical Installation Condition Report) module aligned to BS 7671. Engineers can complete the full inspection schedule, record circuit test results, and log observations with C1, C2, C3, and FI codes.

Whatever your team certifies, CertBase handles it.

Most teams cobble together a different tool for each service line. CertBase is one engine — discipline-agnostic templates, results and certificates — so adding a new service is a setting, not a migration.

CertBase on iPhone

The whole job —
in one pocket.

Built around the actual day of a field engineer — open the app, see what's next, scan a tag, capture readings from your tester, sign and send the cert. No tabs. No "save and continue later".

Pairs with your tester

Bluetooth to Seaward Apollo, Megger, Metrel — readings drop straight into the item. No re-keying numbers.

One-screen item capture

Asset, visual, three measurements, pass/fail — captured on a single thumb-reachable view.

Sign-off on the device

Customer signs on the glass, certificate emails before you leave the building.

Offline-first by default

No signal in the basement? Carry on. The queue indicator tells you exactly how many records are waiting to sync.
