Assessment Information:

Engineers who have the necessary pre-requisites to be admitted onto the ACS Scheme run by one of our approved centres to enable registration with Gas Safe.

These engineers are classified into 2 categories:
Category 1 – Experienced practicing gas fitting operative
Category 2 – Applicants will hold qualifications detailed in Guidance Note 8 and provide written evidence to the assessment centre confirming that they have undertaken work experience and training for the range of assessments to be undertaken.

That evidence shall include:

• a written statement from a registered business detailing precisely the type, range and volume of gas work carried out.
• a certificate of achievement or written statement from the training provider where the gas training has been carried out.

or

Are undertaking a vocational qualification which has a requirement of gas work to be included, and where ACS certification is an integral part of that qualification

or

Meet the requirements of guidance note 8a (Candidates with Gas work experience gained legally from sectors of Industry outside of the scope of the Gas Safety Installation & Use Regulations).

Please Note: Applicants that do not satisfy the criteria of Categories 1 or 2 shall be classified as a new entrant to the industry and considered as Category 3 applicants."

Successful completion of the Core Domestic Gas Safety – LPG or changeover qualification is a pre-requisite before gas engineers can undertake additional assessment on LPG fuelled installations and appliances.

Liquefied Petroleum Gas core assessment has two parts Generic Part A + Specific Part B (depending on the type of Dwelling)
LPG Core
Codes	Description
CCLP1	Core Domestic LPG Safety
CCLP1 is a Core Gas Safety qualification and is required for any gas engineer wishing to work on Liquefied Petroleum Gas (LPG) installations. Note: CCLP1 does not stand alone and should have a dwelling listed below with it
CCLP1 PD	Domestic LPG Permanent Dwellings
CCLP1 RPH	Domestic LPG Residential Park Homes
CCLP1 LAV	Domestic LPG Leisure Accommodation Vehicles
CCLP1 B	Domestic LPG Boats

Changeover Domestic Natural Gas to LPG
CoNGLP1 is a “fuel changeover” assessment that allows gas engineers who currently hold (Natural Gas) qualification (e.g. CCN1) to work on LPG installations. The assessment only covers the fuel characteristics that are different between LPG and Natural Gas.
Codes	Description
CoNGLP1	Changeover from Domestic Natural Gas to LPG
Gas engineers working on LPG installations will need to hold relevant appliance qualifications. Permanent Dwellings (PD) and Residential Park Homes (RPH); Most appliances found in this type of property are the typical domestic appliances normally found under the following categories: CENWAT1 Domestic Central Heating Boilers and Water Heaters CKR1 Domestic Gas Cookers DAH1 Domestic Air Heater HTR1 Domestic Gas Heaters LEI1 Leisure appliances LAU1 Domestic Laundry CPA1 Combustion Performance Analysis WAT1 Domestic Instantaneous Water Heater Where an existing engineer already holds ACS qualifications in these areas, they will be automatically eligible to work on these appliances irrespective of whether they are fuelled by natural gas or LPG.
CoNGLP1 PD	Domestic Natural Gas to LPG Permanent Dwellings
CoNGLP1 RPH	Domestic Natural Gas to LPG Residential Park Homes
CoNGLP1 LAV	Domestic Natural Gas to LPG Leisure Accommodation Vehicles
CoNGLP1 B	Domestic Natural Gas to LPG Boats

LPG Specific Appliances
There are a number of “sector specific” appliances that are used in these two areas which have different installation, commissioning and servicing criteria that reflect the types of situations and locations in which they are to be found, as per the list of assessments below:
Codes	Description
HTRLP2	Install, Exchange, Service, Repair, Breakdown and Commission Closed Flue Gas Fires – LPG
HTRLP3	Install, Exchange, Service, Repair, Breakdown and Commission Caravan Space Heaters – LPG
REFLP2	Install, Exchange, Service, Repair, Breakdown and Commission Caravan Gas Refrigerators – LPG
WATLP2	Install, Exchange, Service, Repair, Breakdown and Commission Caravan Gas Water Heaters – LPG

LPG Pipework
Codes	Description
CCLP1 EP	External Pipework
VESLP1	Gas Storage Vessel Connections, Controls and Safety Requirements. Sizing External Above Ground and Unjointed Buried Below Ground Pipework of up to 0.1 m3 in Volume for Single Gas Supply – LPG
VESLP2	Gas Storage Vessel Connections, Controls and Safety Requirements. Sizing External Above Ground and Unjointed Buried Below Ground Pipework of more 0.1 m3 in Volume for Multiple Gas Supply – LPG
EFJLP1	Polyethylene Electro Fusion Jointing for Single and Multiple Liquefied Petroleum Gas Supply
