Business insurance: what you need

Understanding mandatory and recommended insurance for your business, including employers' liability, public liability, professional indemnity, and sector-specific cover.

Starting a construction business requires understanding specific legal obligations that apply to the construction sector. These include the Construction (Design and Management) Regulations 2015, health and safety requirements, waste carrier registration, and appropriate insurance coverage.

CDM 2015 compliance

The Construction (Design and Management) Regulations 2015 apply to all construction work. Understanding notification thresholds and duty holder responsibilities is essential before you start trading.

Health and safety requirements

All construction businesses must comply with health and safety law from day one. This includes risk assessments, safety policies, and worker training.

Asbestos management

If you work on non-domestic buildings (or common areas of domestic buildings), you need to understand your legal duty to manage asbestos.

Waste carrier registration

Construction businesses that transport waste (including their own waste) must register as waste carriers. This applies even if you only transport your own construction waste to a tip.

Construction Industry Scheme (CIS)

If you work as a contractor paying subcontractors, or as a subcontractor receiving payments from contractors, you need to understand the Construction Industry Scheme for tax deductions.

Insurance requirements

Construction businesses must have appropriate insurance coverage from day one. The industry is high-risk, so understanding which insurance is legally required and which is essential for protecting your business is critical.
