What your students practice

The unvented hot water (G3) certificate shows a plumber or heating engineer is competent to install unvented hot water cylinders under Part G3 of the Building Regulations. Awarding bodies such as BPEC and LCL Awards run it as a short course with a multiple-choice theory paper and a practical assessment, covering system types, inlet controls, the two independent safety devices, tundish and discharge pipe rules, temperature control, commissioning and maintenance. BPEC certificates last five years.

Tigertest's practice follows BPEC's unvented hot water qualification page and Approved Document G (2015 edition with 2016 and 2024 amendments), checked November 2026. Students train in short sets where missed questions come back until they are mastered, then take full practice tests.

Questions teachers ask

Is the Unvented G3 class free?

Yes. Classes are free for teachers. A student in your class also gets that test's full stats and every step of it at no charge.

Do my students need accounts?

No. A student opens your class link, types the name you know them by and starts practicing. An account is optional and keeps their progress across devices.

What do I see as the teacher?

Who practiced and when, each student's practice test scores, the Unvented G3 topics the class is weakest on, and every question the class answered with how many missed it and which wrong answer they picked.

Can I use my own questions too?

Yes. Any account can turn its own material into a Tigertest quiz and limit it to one class, so only your students can play it.
