What CEng and IEng actually are
Chartered Engineer (CEng) and Incorporated Engineer (IEng) are titles held on a national register kept by the Engineering Council. You don't apply to the Engineering Council yourself. You go through a professional engineering institution it has licensed to assess candidates, and for electrical people that is usually the IET (Institution of Engineering and Technology).
Only people on the current register can use the titles, and registration renews every year through your institution membership. There is no general ban on working as an engineer without a title. Some safety-related work is reserved for licensed or approved people, though, and CEng is the recognised mark of competence at senior level.
The UK-SPEC standard you are judged against
Every application is judged against the UK Standard for Professional Engineering Competence and Commitment, known as UK-SPEC. The fourth edition came out in August 2020 and had to be in use by 31 December 2021. It sets out five areas for each title: knowledge and understanding; design, development and solving engineering problems; responsibility, management and leadership; communication and interpersonal skills; and professional commitment.
The commitment side is more than box-ticking. The IET wants evidence that you keep people safe, protect the environment, follow codes and the law, run safe systems of work, keep up your CPD, act ethically, take inclusivity and security seriously, and play a part in the profession. Collect real examples from your own projects as you go. It is much harder to dig them out years later.
Degree route or experience route
The standard academic base for CEng is an accredited Master's in engineering, an integrated MEng, or an accredited honours Bachelor's plus further learning to Master's level. If you have none of these, you can still apply. The IET runs non-standard and experiential learning routes where you show the same level of knowledge through your work. At the pre-interview stage the IET may ask for extra evidence, such as work-based learning.
This matters for electricians. Plenty of people start on the tools, register as EngTech or IEng, and move up to CEng later. The IET says many of its technicians and Incorporated Engineers use registration as a step towards chartership. Engineering Council material describes IEng as the title for people who maintain and manage applications of current and developing technology.
What it does for a career
CEng is recognised internationally and shows employers and clients that a panel of your peers has checked your judgement. The IET says registered engineers often move faster into leadership, consultancy and specialist roles.
Keeping the title takes ongoing effort. You have to stay a member of the IET, pay its registered member fee plus the Engineering Council's annual fee, and keep up regular CPD. The IET's Career Manager tool records your CPD and your evidence for the application.
Pay
GBP a year, before tax. Ranges run from the 25th to the 75th percentile for electrical engineers in general, based on ONS Annual Survey of Hours and Earnings April 2026 (provisional) data brought up to date with a wage index. Regional figures are modelled. They don't separate out chartered engineers, who usually sit towards the upper end. Refer to the Electrical Engineers salary guide for figures from live adverts.
What you need
- Institution membershipYou have to be a member of the IET, or another licensed institution, before you apply, and you have to stay a member to keep the title.
- Academic base for CEngAn accredited Master's, an integrated MEng, or an accredited honours Bachelor's plus further learning to Master's level. If you don't have one of these, you can use the non-standard or experiential route.
- UK-SPEC competenceEvidence from your own work across all five UK-SPEC areas, from technical knowledge through to leadership and professional commitment.
- SupportersYou need one supporter who can vouch for your competence and conduct, and you can add up to two more.
- Professional review interviewThe interview is compulsory for CEng and IEng. It lasts about an hour, including a presentation of about 15 minutes, and IET members who are registered themselves run it.
- FeesThe IET charges £261 to apply for CEng or IEng, and the fee isn't refunded whatever the outcome. Once you pass, there is an Engineering Council entrance fee of £64.31 for CEng or £54.29 for IEng.
- Ongoing CPDTo keep the title you have to do regular continuing professional development and renew your registration every year.

- OngoingBuild and record your evidenceUse Career Manager to log projects and decisions against the UK-SPEC areas. If you haven't got the standard degree, plan your experiential learning evidence.
- When readyLine up supporters and applySend in your competence evidence, your higher education certificates and your supporters' names, then pay the £261 application fee.
- After applyingPre-interview reviewIET staff check the application is complete. Then registered members assess it and may ask for more evidence of competence or knowledge.
- After reviewProfessional review interviewThis is about an hour of professional discussion with a presentation of about 15 minutes. Interviews can be face to face or by video conference.

Questions people ask
Do I need a Master's degree to become a chartered engineer?
No. The accredited Master's or MEng is the standard route, but the IET also accepts applicants through non-standard and experiential learning routes. On those routes you have to show the same level of knowledge through your work.
What is the difference between CEng and IEng?
Both titles are judged against UK-SPEC and both need a professional review interview. CEng is the higher level and covers developing solutions to complex engineering problems and leading at senior level. IEng covers maintaining and managing current and developing technology.
Can an electrician become a chartered engineer?
Yes. Many people register first as EngTech or IEng and later move up to CEng. The IET says many registered technicians and Incorporated Engineers use professional registration as a pathway to CEng. If you don't have the standard degree, you will need to prove Master's-level knowledge through your experience.
What happens at the professional review interview?
Two or more trained IET members who are registered themselves interview you for about an hour. You open with a presentation of about 15 minutes, then talk through your experience and competence. Interviews can be face to face or by video conference.
What if I fail?
The IET will tell you what to do next. If you reapply within three years of your interview, the fee is £188 instead of the full £261. You can also appeal for £188, which is refunded if the appeal succeeds.
How much does it cost each year to stay chartered?
Once registered you pay the IET's qualified and registered member fee plus the Engineering Council's annual registration fee. You also have to keep up your CPD and stay a member.
