Gas Meter Installer Training

Lesson 1 • Hazard Identification and Risk Assessment

Teaches systematic identification of gas, electrical, and physical hazards at meter sites. Prepares installers to complete risk assessments before beginning any job.

Lesson 2 • Personal Protective Equipment and Site Safety

Covers PPE selection, inspection, and correct use for gas meter work environments. Directly reduces injury risk during all practical installation tasks.

Lesson 3 • Gas Distribution System Overview

Explains transmission, distribution, and service line hierarchy from supply source to meter point. Provides context for where the meter installer operates within the wider network.

Lesson 4 • Regulatory and Compliance Framework

Introduces the regulatory bodies, competency schemes, and safety standards governing gas work. Ensures installers understand their legal obligations before entering the field.

Lesson 1 • Rotary and Turbine Meter Types

Covers impeller-based and turbine meter designs used in commercial and industrial applications. Expands installer competency beyond residential meter work.

Lesson 2 • Ancillary Components and Fittings

Identifies governors, emergency control valves, unions, and filter assemblies used in meter installations. Ensures correct component selection and assembly during installation.

Lesson 3 • Diaphragm Meter Construction

Examines the internal valve, diaphragm, and index assembly of the most common residential meter type. Provides the mechanical understanding needed for correct handling and installation.

Lesson 4 • Meter Capacity and Selection Criteria

Applies load calculations and diversity factors to select the correct meter size for a given site. Links component knowledge to practical decision-making in the field.

Lesson 1 • Pressure Testing Equipment

Introduces manometers, electronic gauges, and test equipment used to verify installation tightness. Accurate pressure testing is compulsory before any meter is commissioned.

Lesson 2 • Lifting and Handling Equipment

Addresses manual handling techniques and mechanical aids for moving heavy meter assemblies. Prevents musculoskeletal injury and equipment damage during installation.

Lesson 3 • Jointing Compounds and Sealing Materials

Covers approved thread sealants, PTFE tape application, and anaerobic compounds for gas service. Incorrect sealant use is a leading cause of installation leaks.

Lesson 4 • Hand Tools for Gas Work

Covers wrenches, pipe cutters, reamers, and thread-cutting tools specific to gas pipework. Proper tool selection prevents damage to fittings and ensures joint integrity.

Lesson 1 • Identifying Non-Standard Site Conditions

Addresses unusual site conditions such as flood risk, corrosive environments, and restricted access. Prepares installers to escalate or adapt plans when standard procedures are insufficient.

Lesson 2 • Customer and Site Documentation

Explains pre-installation documentation including site surveys, customer consent, and job records. Accurate records protect the installer and support downstream billing and safety audits.

Lesson 3 • Meter Location Requirements

Defines approved and prohibited meter positions relative to ignition sources, ventilation, and access. Correct siting is the first step toward a compliant installation.

Lesson 4 • Existing Infrastructure Assessment

Teaches inspection of incoming service pipes, existing fittings, and structural supports at the site. Identifies defects that must be resolved before new meter installation proceeds.

Lesson 1 • Reinstating and Purging the Supply

Explains controlled reinstatement of gas flow and purging of air from the new meter assembly. Correct purging prevents ignition of air-gas mixtures during appliance relight.

Lesson 2 • Removing an Existing Meter

Details the sequence for disconnecting, capping, and removing an in-service meter safely. Correct removal prevents pipe stress, leaks, and damage to downstream appliances.

Lesson 3 • Isolating and Purging the Supply

Covers safe isolation of the incoming gas supply and purging procedures before meter removal or fitting. Prevents gas release and ignition risk during the installation process.

Lesson 4 • New Service and First-Fix Installations

Addresses installation of meters on new service connections where no prior meter exists. Builds on removal and replacement skills to cover the full first-installation workflow.

Lesson 1 • Locating and Rectifying Leaks

Covers leak detection methods including gas detectors, leak detection fluid, and ultrasonic tools. Installers must locate and repair all leaks before proceeding to commissioning.

Lesson 2 • Conducting the Meter Installation Test

Details the step-by-step tightness test procedure applied immediately after meter installation. Ensures the meter and all new joints are gas-tight before supply reinstatement.

Lesson 3 • Downstream Installation Tightness Test

Extends testing to the downstream pipework and appliance connections beyond the meter outlet. Confirms the entire installation is safe before appliances are relighted.

Lesson 4 • Commissioning and Handover

Covers meter index recording, appliance relight, customer briefing, and completion documentation. Proper commissioning closes the installation process and transfers responsibility to the customer.

Lesson 1 • Diagnostic Investigation Techniques

Applies pressure measurement, flow testing, and visual inspection to confirm fault root causes. Accurate diagnosis prevents unnecessary meter exchanges and repeat visits.

Lesson 2 • Planned and Emergency Meter Exchange

Covers the full exchange workflow for both scheduled replacements and emergency fault responses. Builds on installation skills to handle time-critical and complex exchange scenarios.

Lesson 3 • Unsafe Situation Identification

Identifies conditions requiring immediate supply isolation, including tampering, corrosion, and damage. Installers must recognise and respond to unsafe situations without delay.

Lesson 4 • Reporting and Escalation Procedures

Defines when and how to escalate faults beyond the installer's scope to network operators or engineers. Clear escalation prevents unsafe situations from being left unresolved.

Lesson 1 • Quality Assurance and Self-Audit

Introduces post-installation self-audit checklists and quality assurance practices used by professional installers. Embeds a culture of continuous quality improvement in field operations.

Lesson 2 • Commercial and Industrial Meter Sets

Covers larger rotary and turbine meter installations with associated regulators, filters, and bypass valves. Extends competency to higher-volume, higher-pressure commercial applications.

Lesson 3 • Multi-Occupancy and Shared Service Installations

Addresses meter installation in apartment blocks and shared service arrangements with multiple consumers. Requires coordination skills and understanding of shared infrastructure responsibilities.

Lesson 4 • Retrofitting Smart Meters to Existing Installations

Covers the specific challenges of replacing legacy meters with smart meter assemblies in existing pipework. Addresses communication module configuration and customer data migration.
