Stage 2 – Work-based Competence & Gas Portfolio of Evidence Building

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 Training Centre we provide every single student that we train, a 100% written guarantee of a work placement, with an immediate start, in the student’s local area.

  • Guaranteed Work Placement
  • Portfolio of Evidence
  • Gain On-Site Experience
  • Local to You
  • Minimum of 18 weeks
S3 Stage 3

Stage 3 – High Intensity Training & ACS Assessments

2 weeks full-time

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 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.

Stop thinking about doing the course and get it done.I was a hgv driver for over 15 years no experience in plumbing and gas and was threatening to do the course for a while just wish I had done it sooner.Please don't think u can just attend and pass coz u can't. If u put the work in and study u can pass and succeed. There was times on the course I was thinking how am I going to pass this and wish I hadn't of started it. But after the placement and studying it all sinks in trust. My tutor Chris is a top guy helped with anything I don't understand. Placement was very good I got took on straight away after passing my acs. It took me all in 6 months so it can be done. So it's been just over a year now that I've been employed, the company I work for have paid me to do cookes/fires/Lpg all qualified now. Also I have been doing some jobs of my own aswell. Get it done 5 STAR 100%

I left the Royal Marines after 15 years, having only ever known one employment. The gulf between careers seemed massive.Brook house bridged that gap perfectly. The staff all have a genuine investment in your success.The training and facilities are excellent and leave you well prepared for what you will encounter on site.The work placement was brilliant and selected with care to put you in a strong position to complete your portfolio and ACS.Upon completion Brook house provided advice and support to help me find employment…. 3 days later I was employed.I can’t thank the team enough…well worth it !!

Can't fault this place at all. It was a great place to learn, the tutors were very knowledgeable and patient. It is a fast paced course especially if you have no previous plumbing/gas experience, but if you take their advice to revise and read the books provided it makes it a lot easier to take it all in.My placement was a bit up and down. My placement was cancelled at the last minute but BTC had set me up with another but this could only be for a month. During that month BTC had kept on it and arranged a permanent placement who I am now fully employed with. Cheers Tim. When on placement I needed to get in contact with my tutor for a couple of questions. He was easy to get hold of and was happy to help. Cheers John.All in all I am very happy that I chose Brookhouse and would recommend to anyone.Thank you all at BTC

Best decision I've made with my life.I qualified in around 7 months and got a job with British Gas immediately after passing. The instructors were great, really knew their stuff.Portfolio jobs were marked off by staff usually within a week. Guaranteed placement was good but there were a few issues such as not doing enough gas jobs but it was sorted by brookhouse.£7,000, leaving a job and 6 months unpaid training is a big decision to make. It paid off massively for me. I've now got a career I love, a large payrise and a job I enjoy.A few tips-Study hard, it's a fast paced course.-Have a plan of what you want too do after, I'd recommend employment after. 6 months isn't enough to go self employed I feel.-worth getting accommodation so you can focus on course.
