Specialist Professional Registers​

Do you wish to be recognised at the highest level as an expert in land condition, contaminated land assessment, remediation and brownfield regeneration?

CIWEM is a supporting member of the Specialist in Land Condition Register (SILC) that recognises the highest calibre of senior practitioners within the industry. Its members can also achieve Suitably Qualified Person (SQP) status under the government recognised National Quality Mark Scheme (NQMS) and are uniquely qualified to verify land condition reports associated with planning applications and other regulatory processes.

The benefits of being a SiLC include professional recognition that you are at the pinnacle of your profession. You are permitted to use it to promote your practice. As an SQP you will also be able to undertake work that non-registered people cannot.

To become a SiLC you must be Chartered and will need to undergo an exam and interview process. The exam is set by the SiLC Professional and Technical Panel (PTP) and the interview is conducted by a panel of two assessors and an observer – all of which are SiLCs. There is also a mentoring scheme (SiLC Affiliate Scheme) for those who would like support for their professional development to becoming chartered initially and then applying for SiLC in the longer term.

To find out more please visit where you can obtain details of the SiLC Affiliate Scheme, Introduction Days, the exam process, the NQMS and the role of an SQP.

Chartered Engineers (CEng) can apply for additional registration as a European Engineer. This entitles you to use the letters EUR ING before your name – for example, EUR ING K Thompson MCIWEM C.WEM CEng.

The EUR ING title shows your ability as a professional engineer, and recognises your education, training and experience. However, because EUR ING is not a regulated title, it does not give you any legal rights to register in other European countries.

Your registration is assessed by the the European Federation of National Engineering Associations (FEANI).

The Engineering Council is the UK member of FEANI and they manage the registration process for Chartered Engineers, but applications from MCIWEM C.WEM CEng have to be submitted via CIWEM.

How to apply

From the 01 January 2023 EUR ING applications will be made directly by candidates via an online application tool on the Engineering Council’s website. Therefore, the final date applications can be made through CIWEM must meet the Registration Deadline of 21 October 2022 (for EMC meeting of 212-2 November 2022).

If you are MCIWEM C.WEM CEng, please download the guidance and application form from the Engineering Council website and email your completed documents to

We will check and process your application before sending it to the Engineering Council for assessment.

The assessment decision will be sent to you directly by the Engineering Council.

Fees and renewal

The application fee is £210 which should be paid online to CIWEM following submission of documents.

You must renew your EUR ING registration every five years, and renewals currently cost £45. You will be sent an invoice by the Engineering Council towards the end of the five year period to remind you to renew your registration.
