Code of Construction Practice Consultation

The council is now consulting on our Code of Construction Practice 2021 (CoCP).

We want Westminster to be known for leading the way in tackling climate change and improving air quality.

We want our children to inherit not just a more equitable, better and healthier living environment but also a working model for how a global city can successfully take on the environmental challenges facing the next generation.

To build a cleaner and greener city we are launching a range of ambitious new policies that work together to improve air quality and deliver on our climate emergency target for the council to be carbon neutral by 2030, with the whole city to follow suit by 2040.

The Code of Construction Practice (CoCP) sets ambitious new standards for developers to meet to manage the environmental impact of construction works. The CoCP works alongside:

  • the City Plan which sets out strategic policies for land use and new development
  • the Environment Supplementary Planning Document which provides further detailed guidance on the environment policies in the City Plan
  • the freight, servicing and delivery strategy and action plan which sets our partnership approach to re-timing, re-moding and reducing deliveries across the city
  • the Air Quality Action Plan which details the actions we are taking to improve air quality across the city 

The guidance in the Code ensures that detrimental impact of construction is minimised. It is also cross cutting guidance for our planning, highways and pollution services. It is part of our commitment to creating a cleaner, greener City for All,  including carbon reduction, climate resilience, city greening  and reducing air pollutants.

The Code

The Code of Construction Practice covers:

  • community consultation – setting out the most effective ways to keep affected communities informed of activity on site
  • site operations – ensuring that health and safety, security, lighting, hoardings, facilities and site layout , pest control, temporary structure and crane locations comply with council and industry standards
  • highways and transport – maximising road safety through Traffic Management Plans to ensure safety on and adjacent to sites
  • noise and vibration – control and limit noise and vibration levels through risk assessment and specific working hours
  • dust and air pollution – minimise dust and air pollution on site with low and zero carbon non-road machinery and equipment and risk assessment
  • waste management – reducing waste on site through re-use, recycling, and utilising circular economy opportunities
  • water pollution and flood risk – protecting surface and ground water from pollution and minimising the risk of flooding
  • urban ecology – ensuring that construction practises do not have a damaging impact on protected and priority species and appropriate tree protection and replacement
  • heritage assets – assessing the archaeological impact of proposals and the impact on listed building and conservation areas
  • protection of existing installations – sets out the requirements for condition surveys and procedure for ensuring cables, utilities, structure foundation and other infrastructure is protected
