SULF during the summer


We will soon be taking a summer break, so our website will not be updated regularly. However, the SULF switchboard is reachable by phone on weekdays between 9.00 and 11.30 all summer. 

Members’ support and membership services

During weeks 26-33, (24 June-16 August), the SULF members’ helpline and the SULF membership service have shorter opening hours than normal.

The members’ support service can be contacted weekdays by email at When you write to us, please take the opportunity to check that your details in the membership register are up to date. Please also make sure that you include your contact details in the email so that we can also reach you by phone if necessary. This is especially important during the summer, when support is only available via email.

Our membership register service is open at 9.00-11.30 on Mondays, Wednesdays and Fridays during the summer, apart from week 28 (8-12 July) and week 31 (29 July-2 August), when the service will be closed. You can call us on 08-505 836 00 or email us at

We wish you a lovely summer and look forward to seeing you after the holidays.
