Our Accreditations


On 4th July 2009, it became the law for any business involved in the installation, maintenance and servicing of stationary air conditioning, refrigeration and heat pump equipment with F-gas refrigerant to complete the relevant F-gas company certification process.

REFCOM is the UK’s market leading F-gas registration scheme and sets an industry standard. LH-Plc holds the REFCOM Elite Certificate – the REE1000239. This certifies that all of our engineers are fully qualified, ensuring they are competent in the safe handling of F-Gas refrigerants and systems.

In order to comply with the certification, the company must keep the appropriate refrigerant recovery equipment on site and available for use by the engineers. Procedures must also be put in place to ensure the correct and safe handling of the systems and refrigerant.


Our registration with REFCOM Elite is a hallmark of competence, reassuring owners and operators that we have passed the stringent accreditation process, following an independent third party inspection.

As a registered company, the REFCOM Elite registration proves our engineers can competently commission, install and maintain any system containing refrigerant. It also proves that we are compliant with the current legal industry requirements, that we are licensed waste carriers and that we handle refrigerants safely.

It also lets owners know we complete auditable procedures to ensure the proper control of refrigerants, ensuring all that are used and recovered are accounted for, using purpose-designed refrigerant recovery equipment.

REFCOM Elite is also an indicator that we are an environmentally aware company, performing refrigerant transactions with minimum emissions.


LH-Plc is also a member of the UK’s leading third party health and safety accreditation programme, the Safe Contractor scheme. This certifies that member companies are following the latest guidelines and complying with the sector’s relevant legislation.

A growing list of major clients in the UK requires contractors to be members of the scheme. These include Lloyds Banking Group, Sainsbury’s, Marks and Spencer, Tesco Stores Ltd, Next Retail, Heineken UK, Nestle UK Ltd and Kellogg’s UK, to name but a few.

A Safe Contractor registered businesses will work to the highest industry standards, that are required by Great Britain’s leading companies.
