Trade Specifications
The following Trade Specifications must be read in conjunction with all other Contract documentation including; Tender Letter, Operating Procedures for All Contractors, Conditions of Contract for Works, Labour Only and Purchase Orders, General Construction Notes (England & Wales), Suppliers and Sub Contract Works - SLA and the Company's Occupational Safety, Health & Environmental Management System.
Our aim is to enable our sub-contractors and suppliers to access key Commercial information such as Terms & Conditions, Trade Specification, etc. online as soon as they are updated and revised. We hope that this will ensure that our supply chain is always fully informed as quickly as possible.
Whilst available online, this information is also available from the Commercial Departments at our Divisional offices and will form part of any contract we place (as set out in the Order).
Please be aware that bogus web sites seeking fees for the chance of working with major contractors exist.

Roof Tiling
Revision AE 01.01.2024
Section 2 has been amended to advise that all underlay must have 3rd party accreditation by BM TRADA, KIWA, BRE or BBA.
Amendments have been made to instruct the Contractor to neatly cut through the roof, including panellised roof systems and supply and install the vent terminal including adaptor through the underlay in readiness for connection by others.
Due to a requirement for ventilation terminals to meet the requirements for Mechanical Extract Ventilation, the use of 3rd party products is only permitted where approval has been provided by the tile manufacturer.
Roofing Contractor is to provide and install expanding foam tape to dormers, and chimneys to fill the gap at any exposed tile edges to prevent ingress into the roof from wildlife and driving rain.
