Direct Answer
Technical Writer salaries range from £25,000 to £605–£895/day. Technical Writer with NHS DTAC evidence pack experience (IEC 62304 software design documentation, DTAC domain responses — often written by Technical Writers on larger NHS HealthTech programmes) commands NHS premium. Technical Writer with OpenAPI 3.0 documentation (REST API documentation in Swagger/Redoc format — ideally generating from Zod schemas) commands premium. Technical Writer with GDS Technical Documentation (GOV.UK-style docs — GDS Tech Docs Generator, clear plain English technical content for government) commands government premium.
Market Outlook
Technical Writers produce documentation for software products — API documentation (OpenAPI 3.0), developer guides, user manuals, and technical specifications. The UK Technical Writer market rewards writers who understand the products they document — API Technical Writers (who can read code and write OpenAPI specs) command significant premium over word-processing-only technical writers.
