About GasTheory
GasTheory was created to make gas training clearer, easier and more accessible for engineers and students in the UK. The aim is simple: structured lessons, challenging questions, and a modern place to revise that you can actually trust.
Accurate & Up-to-Date Gas Content
All lessons and questions are written to reflect current UK gas legislation, industry standards and manufacturer guidance. Topics are organised the same way you'll see them in real training: regulations, combustion, ventilation, pressure, pipe sizing, appliances and fault-finding.
The goal is to give you clear explanations that match how gas is actually assessed in college, on site and in formal qualifications.
Questions Built for Real Learning
GasTheory doesn't rely on simple "spot the pattern" quizzes. Question sets are designed to stay challenging, even after multiple attempts.
- • Correct answers are randomly positioned each time.
- • Questions you answered incorrectly are shown first on your next attempt.
- • Wording and options are varied so you learn concepts, not just answer order.
- • Explanations help you understand why an answer is right or wrong.
Built for Real Engineers & Students
GasTheory is designed to support you at every stage of your gas journey:
- • New learners – break down complex topics into clear, guided lessons.
- • Existing engineers – refresh core knowledge before assessments or when returning to gas work.
- • Multi-trade workers – gain confidence when adding gas to your skill set.
Independent. Focused. Easy to Use.
GasTheory is an independent revision platform built specifically for gas training. It isn't tied to any single training provider or publisher — the focus is on clarity, accuracy and a great learning experience.
The mission is simple: to make gas training clear, structured and stress-free, so you can focus on becoming a safe and confident gas engineer.
What's Coming Next
Over time, GasTheory will grow with more topic quizzes, mock exams and deeper explanations. The long-term plan is to give you everything you need in one place — from fundamentals to advanced fault-finding.
Feedback from learners and engineers will shape future updates, so the platform always reflects what's most useful in real training and on real jobs.
