Donations to the Member's Benevolent Trust (MBT) fund

IOM3 strongly supports the work of the MBT in assisting members or their families in times of hardship. The fund is financed by donations and is separate to the Institute. Those wishing to donate can do so when you pay your membership fees.

Donations are allowable for Gift Aid for UK taxpayers – please indicate when making payment. 

Support from the MBT

If you are experiencing financial difficulties and wish to be considered for Benevolent Trust assistance, please write in confidence detailing your circumstances to the Honorary Secretary, either by email to [email protected] or by post to Member’s Benevolent Trust, c/o The Institute of Materials, Minerals & Mining, 297 Euston Road, London NW1 3AD. More details of the types of support and how to apply are available on the MBT web page.

TMS and ASM International e-memberships

IOM3 has partnership agreements with two major professional organisations in the US, whereby an additional fee to your IOM3 membership subscription gives you access to a wide range of online benefits. TMS (£37) and ASM International (£35) e-membership is not renewed automatically – you need to opt in as follows:

DD payers – please notify us straight away if you wish to take up either or both subscriptions.

Non-DD payers – please add the e-membership subscription when you pay online. If you wish to add this during the year after you have renewed your subscription, please contact us.

Members who opt in to these e-memberships will have their contact details passed on to TMS and/or ASM International for the purposes of registration as members of these organisations and access to benefits.

Registration as CEng, IEng, EngTech, CSci, RSci, RSciTech, CEnv and REnvP

Registration fees are collected by the Institute on behalf of the Engineering Council, the Science Council and the Society for the Environment. If you are registered through two or more professional institutions, you should pay only one fee through the institution of your choice. The amount due from you is shown along with your IOM3 subscription.
