What it is
You use GIS software to build maps, tidy up location data and answer questions such as where sites sit in relation to flood zones, roads or boundaries. Work is delivered as map files, PDFs, datasets or short reports.
Your first three steps
- Build a portfolio of 3 to 5 sample maps using free tools like QGIS and open data (Ordnance Survey OpenData, data.gov.uk)
- Pick a niche such as planning, environmental, property or utilities, and list 30 local firms and councils to contact
- Set up as a sole trader with HMRC, then send your portfolio to your list and offer a small paid trial project
Who pays
Councils, planning and environmental consultancies, housing groups, estate agents, charities and small businesses that lack in-house mapping skills.
How it makes money
Fixed price per project or a day rate, often with repeat work from the same clients. Small jobs might be a single plan; larger ones are multi-week analysis.
Skills that help
- GIS software such as QGIS or ArcGIS
- Data handling and spreadsheets

- Handling personal or sensitive location data may bring UK GDPR duties, and you may need to register with the ICO
