About this deal

As well as more minor changes to Chapters 3.3, 5.1, 6.2, 6.4, 6.7, 6.8, 9.5, the following major technical changes have been made to this edition of the Standards: The six-month transition period allows electrical contractors to understand and apply the changes outlined in the amendment. From September 2022, anyone working in the electrical sector must comply with the latest regulations set out in Amendment 2. Chapter 6.1 - new guidance on the provision of horizontal movement joints on masonry clad buildings and increasing cavity wall performance standards Chapters 8.1 to 8.3 - amended in readiness for the carbon reduction requirements expected in the Future Homes Standard. New guidance on heat pump design and specification/certification requirements; solar thermal systems; space heating systems Some of these are general good behaviour rules while others are very specific, prescribed obligations.

Anyone who has sailed in the busy waters of the UK will be thankful that the International Regulations for Preventing Collisions at Sea, more commonly known as the COLREGS, were introduced. The Essential Navigation and Seamanship course is a great supporting course for those new to boating, or as a refresher, and is available in a classroom or online. Chapter 5.3 - new guidance on inspection chambers plus additional guidance on surface soakaway design for gardens less than 100m2 in area. For example, rule 9 determines, amongst other things, that a small vessel must not impede a vessel that is so big it can only navigate safely in a narrow channel or fairway.The Standards for Conversions and Renovations provide guidance on the type of project that will be acceptable to NHBC, the scope of the survey(s) and work that will be required. COLREGS set out the conduct of vessels in any condition of visibility, specifically when in sight of each other, and also in or near areas with restricted visibility.They make it clear when you are the stand on vessel, the give way vessel and the correct action to take when in close quarters with other vessels to avoid a collision. They also help you to anticipate the actions of another vessel.

COLREGS are quite simply the 'highway code' or 'rules of the road' when at sea. A commonly held misconception is that COLREGS are a guidance to help skippers understand who has right of way.Wrong. They are the law and a proven breach may lead to prosecution, even if a collision hasn’t occurred. The standards that we, the SRA, and the public expect of individuals (solicitors, registered European lawyers and registered foreign lawyers). Of course, you should continually assess the situation around you to determine if you think a potential collision situation exists. You need to establish what action is expected of the vessels involved, when the action should be taken and whether the action of the give way vessel alone will be sufficient to prevent the collision.This essential update to the IET Wiring Regulations will form the national standard to which all new electrical installations and additions, and alterations to existing electrical installations in the UK are to comply. Chapter7.2 - updates to underlay and sarking, ventilation; vapour control and insulation; battens, fixing of tiles and slates; valleys and hidden gutters and traditional roof arrangements; protection of trussed rafter roofs and bracing requirements CEF's Head of Technical Solutions Darren Staniforth and electrical legend Dave Austin will give you the lowdown: The NHBC Standards define the technical requirements and performance standards for the design and construction of new homes registered with us and provide guidance on how these can be achieved.
