Method Statement for Excavation with Trench Support — UK

UK construction-safety guidance by the Riskora Editorial Team

Pricing or planning excavation with trench support? The compliance pack is usually the part that holds the job up — not the work itself. The combination of unstable soil, hidden services, and heavy plant working close to operatives makes excavation one of the most planning-critical activities on any UK site. The legal position for excavation with trench support is well established. The Construction (Design and Management) Regulations 2015 and BS 6031 require that excavations are properly supported or battered back to a safe angle. The role of the Method Statement is to make the controls explicit, agreed in advance, and capable of standing up to HSE scrutiny.

  • Full scope and description of excavation requiring temporary trench support systems
  • Site-specific hazard identification and risk ratings
  • Risk control: sudden trench collapse burying operatives
  • Risk control: failure of temporary support systems
  • Risk control: ground movement affecting adjacent structures
  • PPE and RPE requirements for all personnel
  • Emergency procedures and response arrangements
  • Competency requirements and training records
  • Communication and briefing procedures

Common Mistakes to Avoid

  • Using a generic template without adapting it to the specific excavation requiring temporary trench support systems conditions
  • Not reviewing the document when site conditions change
  • Missing sign-off from a competent person before work begins
  • Failing to consider sudden trench collapse burying operatives
  • Not addressing failure of temporary support systems
  • Not briefing all workers on the document content before work starts

Example Scenario

In Nottingham, a package manager has just won a contract that requires the same compliance pack as a tier-one main contractor — including a site-specific Method Statement. They open Riskora, choose the closest preset for excavation with trench support, work through the hazards already loaded for that type of work, add the conditions specific to their site, and have a draft document ready for review inside ten minutes. The finished document explicitly addresses sudden trench collapse burying operatives, which the principal contractor would otherwise expect to see written into the pack.
