Four steps to your future

Get gas safe qualified in four simple stages.

We offer two paths to success, depending on your experience. If you have previous experience in the plumbing and heating industry, you could potentially join us in week 3 of the course. However, if you’re completely new to the plumbing world, you can follow these 4 steps to becoming a Gas Safe engineer:

Stage 1

Gas Introduction, including Pipe-skills

Duration - 2 weeks (weekends also available)


  • Professional standard soldering techniques using copper pipe & ‘end-feed’ fittings
  • Pipework fabrication – copper, plastic & steel jointing, TracPipe & press fittings
  • Compression jointing principles
  • Fitting & pressure testing 15mm & 22mm plastic & copper pipework & joints
  • Fitting outside tap – including backflow prevention valve
  • Fitting isolation valves
  • Indirect and direct hot & cold-water systems
  • Fault-finding & repair: hot & cold taps & valves
  • Hot water cylinder commission
  • Sanitation theory, above-ground waste
  • Central heating condensate connections
  • Bathroom 2nd Fix commissioning
  • Basic power tool training
  • How to use various wall fixings: rawl, dry wall, breeze block/brick plug
  • How to quote & price for jobs
  • Common basic gas processes

Stage 2

LCL Awards DNGA3 Gas Foundation Training including Central Heating

Duration - 6 weeks full-time (evenings and weekends also available)

Part 1: Core Gas Safety (4 weeks)

  • Common basic gas processes
  • Maintaining safety in natural gas
  • Applying core gas safety measures
  • Electrical supply & earth continuity
  • Inspection & testing of cookers
  • Inspection & testing of Ducted Air Heaters
  • Inspection & testing of Space Heaters (Fires)
  • Landlord Certifications (CP12s) on Fires & Cookers
  • Safe removal of Domestic meters & installation
  • Installing, servicing & maintaining pipework
  • GIUSP (unsafe situations) and RIDDOR Procedures
  • Ventilation
  • Chimneys/Flues
  • Gas Safety Controls
  • Pipework
  • Gas Regulations
  • Combustion Analysis (flue gas analyser use)
  • CO awareness & effects of CO

Part 2: Central Heating (CH) Diagnostics & Repairs (2 weeks)

  • Component recognition & testing
  • Fault-finding – diagnosis & repair on domestic appliances
  • Electrical multi-meter use
  • Fault-finding of ‘S plan’ & ‘Y plan’ heating systems
  • CP12s on Boilers and Water Heaters
  • Stripping of pumps & repair
  • Specialist manufacturer combi-boiler training
  • CH system design (theory & install)
  • ‘S Plan’, ‘Y plan’ & combi-boiler installation/conversion
  • Radiator & system sizing
  • Chronological 6 bay CH fault-finding & tasks
  • Approved Tracpipe installation

Stage 3

Work-based Competence and Gas Portfolio of Evidence Building

Duration - Minimum 18 weeks

The most important part of the gas training process is building up a portfolio of evidence. You cannot sit your final ACS assessments without a portfolio of evidence, and this can only be gathered by working alongside a Gas Safe registered engineer. Here at Brookhouse, we provide a written guarantee of a work placement to every student we train, with an immediate start, in the student’s local area.

  • Guaranteed Work Placement
  • Portfolio of Evidence
  • Professional On-Site Experience
  • Local to You
  • Minimum of 18 weeks

Stage 4

High Intensity Training and ACS Assessments

Duration - 2 weeks

Once your portfolio has been completed to a sufficient standard required by Brookhouse’s Gas Assessors, you will then be required to undertake a mandatory theoretical and practical assessment to achieve the LCL Awards Certificate of Training, which is compliant with IGEM/IG/1 (The Standards of Training in Gas Work). This certificate will enable candidates to sit the relevant ACS assessments and will be preceded by high-intensity-training to prepare candidates for the final ACS assessments.

ACS Assessments – Core Gas Safety (CCN1) including Combustion Performance Analysis (CPA1)

Plus 1 appliance from the following*:

  • Central Heating Boilers/Instantaneous Water Heaters (CENWAT)
  • Gas Fires (HTR1)
  • Cookers (CKR1)
  • Meters (MET1)

*Providing the student has sufficient time on-site and portfolio evidence for additional appliances, these can be added-on via a ‘bridging course’ at an additional cost per appliance.

On successful completion of the ACS assessments, students will then be able to either seek employment with a domestic gas company or to register with Gas Safe in their own right.

BTC Training Centre Ltd (trading as Brookhouse) is an approved training provider through the Awarding Body LCL Awards. Successful candidates will receive their certification for their CCN1 and additional appliances from LCL Awards.
