Updated contracts launched by HVCA

Three updated commercial and legal contractors have been announced by HVCA Publications, the publishing division of the Heating and Ventilating Contractors’ Association.

The updates are for CL21 Conditions of Trading, CL70 Maintenance Agreement and CC8/11 Conditions of Sub-Sub-Contract.

The revised contracts are designed for use an agreement between clients and contractors or subcontractors, allowing all parties to meet commercial and legal requirements.

The Conditions of Trading offers an agreement for the supply of goods and services, to be used by a hvacr company dealing directly with a commercial end-user. Prior to this publication and in response to current industry requirements, the previous two separate conditions of trading have been amalgamated in the form of CL21.  

CL70 Maintenance Agreement offers a standard form for use by a hvacr company in conjunction with a commercial client, for either a single property or portfolio of projects.

CC8/11 Conditions of Sub-Sub-Contract, now in its fourth adaptation, is for use by a hvacr company who is either sub-contracting work or is undertaking sub-sub-contracted work.

The contracts are free to HVCA members and can be obtained by emailing
