ACS Initial Assessment

Course Duration:

4 Days

Course Not Running

ACS training and assessment is a necessary requirement of being Gas Safe Registered – all gas installers must be Gas Safe Registered by law. The ACS Initial Assessment is designed for engineers whose ACS has lapsed and expired over 12 months ago.

From £2400 inc. VAT


Gas ACS Initial Assessment Course

We offer multiple ACS courses. Our accredited ACS initial Assessment is for existing Gas Safe Registered installers who need to renew their qualifications after expiring for over 12 months. If your ACS is about to expire or expired less than 11 months ago, you can sit the ACS Reassessment. Reassessment must take place every five years for these qualifications to remain valid and you can take your Course up to 6 months before expiry. This course is not an Extension of Scope. If you want to add appliance codes to your qualification, you must enquire about our ACS Extension of Scope Course.

The ACS Initial Assessment covers CCN1 (gas safety) plus four other optional appliances.

CENWAT: Central Heating Boilers & Water Heaters
CKR1: Cookers
HTR1: Space Heaters (including Gas Fires and Wall Heaters)
MET 1: Meters

Five years is a long time and even the most experienced gas engineer might feel a little rusty. We include free refresher training for candidates who want a recap on the theoretical part of the ACS assessment.

What does ACS training entail?

Whether initial, or reassessment, ACS Assessment is broken down into two parts – theoretical and practical examinations.

The theory-based section is an ‘open book’ question paper; you will also have access to British Standards, IGEM Standards, Technical bulletins, and any other relevant documentation that can be used as references along with the training manual.

Practical examinations are completed in VIVA’s purpose-built ACS assessment bays.

What our customers have said

Just recently completed a fault finding course with the ever knowledgeable Roy Fugler.I honestly cannot rate this training centre and Roy highly enough!I completed my ACS training with them over two years ago and they were my number one choice when I decided to expand my knowledge around the inner workings of a boiler and how to diagnose the issues that often arise.I will have to re-sit my ACS again in a few years and there’s only one place I’ll be going. It’s VIVA all the way!
Great course, trainer clearly implemented his knowledge to the class making it clear an understandable
Passed my ACS with Viva, great trainers put me at ease in a relaxed training atmosphere. Roy & Pete are down to earth, helpful and know there stuff. Lindsay was helpful with the paperwork/ portfolio side of the course, which also helped as paperwork isn't my forte.The company they use for placement are also good, made a few new friends and enjoyed the experience with Basi. Would recommend and I will be going back.
Well worth the journey from London! Thank you Roy you have answered many of my questions I have had for many years. Can’t thank you enough for passing on the knowledge which will massively improve me as an engineer for years to come.David
