You describe the work
For a domestic extension, send the drawings, programme, trade list, photographs and details of the occupied home, utilities, deliveries and waste route.
Construction phase plans & site packs
Set the site up properly before work starts.
Every construction project needs proportionate arrangements for managing health and safety. We organise the project facts, responsibilities, site rules and significant risks into a construction phase plan and supporting site pack your team can actually use.
What you receive
Clear documents built around the job.
- A proportionate construction phase plan tailored to the project and contractor role.
- Project management arrangements, responsibilities, consultation and communication.
- Site rules, welfare, emergency, fire, first-aid and reporting arrangements.
- Registers and briefing records selected for the work, not a bloated generic folder.
- Interfaces with designers, subcontractors, occupied premises and members of the public.
What we need from you
The facts are usually straightforward.
- 01Client and dutyholders, project description, programme and key contacts.
- 02Drawings, pre-construction information and the main work packages.
- 03Site access, welfare, utilities, fire arrangements and neighbouring uses.
- 04How subcontractors, changes, inspections and information will be managed.
From enquiry to working document
Once you know the job, we can ask the right questions.
We turn facts into controls
We assemble a concise plan covering responsibilities, welfare, public and family protection, services, structural sequence, fire, dust, work at height and contractor coordination.
You put it into practice
The principal contractor checks the arrangements before work starts, keeps the pack accessible, briefs each trade and updates it when the project or risks change.
Why proper planning matters
Moral
Prevent a worker, neighbour, visitor or family from being injured—or developing an occupational disease years after the work.
Legal
Employers and construction dutyholders must assess risk and plan, manage and monitor work. Companies and individuals can face enforcement and prosecution.
Financial
Poor control can bring delay, rework, lost contracts, higher insurance costs, HSE fees, fines, legal costs and compensation claims.
Criminal enforcement and private liability are separate exposures.
HSE may investigate, serve notices or prosecute. Separately, an injured worker or member of the public may pursue a civil claim for compensation. A document helps only when it reflects the job and its controls are actually provided and used.
HSE enforcement reality
Planning failures can become prosecutions.
These are official HSE case summaries. Fines are imposed by the courts; HSE does not set or collect them.

Builder could not show construction phase plans
After dangerous extension work put a homeowner and two children at risk, HSE found the company could not show it prepared construction phase plans. It later failed to comply with an Improvement Notice and was sentenced in August 2026.

Domestic work is not exempt
HSE states that construction dutyholders must plan, manage and monitor their work so it protects anyone affected, including members of the public. Client duties on domestic projects normally pass to other dutyholders.
