Why this matters for United Kingdom trades
Gas Safe Register (gas), NICEIC (electrical / Part P), and OFTEC (oil heating) are legal requirements — unlicensed work is a criminal offense, and software/insurance must handle RTI, CIS, and VAT natively.
UK trades vendor selection is shaped by mandatory certification (Gas Safe, NICEIC, OFTEC), compressed compliance (HMRC RTI, CIS deductions, auto-enrolment pensions, VAT), and directory-led consumer behavior (Checkatrade, MyBuilder).
