Description
ACS Gas Pro — the complete UK gas engineer toolkit. Over 1,000 exam questions across all six core ACS modules — CCN1, CENWAT, CKR1, CPA1, HTR1 and MET1 — plus on-site calculators, a Quick Reference cheat-sheet library, and MyACS, your CP12 / renewal / CPD logbook.
Every question is grouped by sub-topic, with detailed explanations and references designed to match what you'll see on assessment day.
Whether you're preparing for initial ACS certification, revising before re-assessment, or working on the tools, ACS Gas Pro is built for the job.

10 ON-SITE CALCULATORS
• Gas Rate (U6 / E6 meter, dial-revolution timing)
• Ventilation Required (room sizing, high/low vents)
• Tightness Test (U6, IGE/UP/1B)
• Boiler Sizing (heat-loss / DHW demand)
• Calorific Value Lookup (NG / LPG)
• CO/CO₂ Ratio (combustion analyser check)
• Flue Termination Lookup (distances by appliance type)
• Pipe Sizing (copper, steel, length & load)
• Unit Converter (mbar, kW, m³/h, BTU)
• Unsafe Situation Classifier (ID, AR, NCS — GIUSP)
QUICK REFERENCE CHEAT SHEETS
Searchable cards covering flue distances, CO/CO₂ limits, standard appliance pressures, ventilation requirements, tightness-test pass/fail criteria, the Unsafe Situations Procedure, pipe-sizing tables and a gas-engineering glossary.
