What it is

A small consultancy that combines site visits, sampling or surveys with written assessments and advice. You might start alone and add an associate or junior as work grows, often hiring in specialist labs and surveyors.

Your first three steps

  1. Define two or three services you can deliver well and price them as fixed-fee packages
  2. Arrange insurance, a simple website and a proper contract and terms of business, ideally checked by a solicitor
  3. Introduce yourself to local planning consultants, architects and council officers, and ask to be added to tender lists
Who pays

Developers, housebuilders, local councils, farms, industrial businesses and landowners who need assessments for planning or compliance.

How it makes money

Fixed fees for assessments and day rates for ongoing advice. Framework or retainer arrangements with regular clients can give steadier work.

Skills that help
  • Strong technical grounding in environmental science or engineering
  • Report writing and presenting findings
  • Quoting, project management and bookkeeping
  • Networking with developers, planners and other professionals
Watch out for
  • Professional indemnity, public liability and, once you hire, employer's liability insurance
  • Health and safety on site, including risk assessments and suitable training and equipment
  • Some work may need specific qualifications, accreditations or permits, so check what applies to your services
  • Public sector tenders can take time and paperwork before bringing in work
  • Equipment, lab and subcontractor costs can eat into margins if not built into your quotes
