The engineering profession in the UK is self-regulated using the legally protected titles:
- Chartered Engineer (CEng)
- Incorporated Engineer (IEng)
- Engineering Technician (EngTech)
- Information and Communications Technology Technician (ICTTech)
These titles may only be used by individuals who are registered with the Engineering Council.
Individuals admitted to the register must have been individually assessed by and maintain membership of one of the licensed professional engineering institutions (PEIs) for this purpose by the Engineering Council.
In general, there is no restriction on the right to practise as an engineer in the UK. However, some areas of work, generally safety related, are reserved by statute, regulations or industry standards to licensed or otherwise approved persons.
These areas of work include:
- Aircraft Maintenance (EASA Part 66, Annex III to European Commission Regulation 2042/2003)

- Gas Fitting (Gas Safety (Installation & Use) Regulations 1998, Gas Safe Register)

Becoming professionally registered is recognised as desirable in many fields of engineering employment and for provision of engineering services but is not mandatory. Registration is renewable annually on payment of a registration and membership fee to the relevant Licensed PEI, providing there has been no violation of codes of professional conduct.
