Then please call 07565 114059 (available 8.30am-5.30pm weekdays)

If you have a more routine question e.g.  what is my password, can I pay an invoice, or technical question. Then please email it to

Please do NOT call the above mobile number with routine questions, as it could prevent a real emergency call getting through.

New Log In Details
The new login and password has been sent to members via the printed bulletin.

As part of the move to online membership processing, direct members of CLEAPSS (ie not via a local authority or other brokering organisation) will have been sent a renewal notice by e-mail. We have sent out over 2500 electronic requests and so far almost half of those we have contacted have successfully navigated the online membership renewal process.If the renewal request has been passed to you by someone else and you are not sure what to do next, give us a ring (01895 251496) and ask us to resend the renewal directly to you. That way you can simply click on the link in the e-mail to access the online portal. 

If your school has not renewed its membership by the end of January, membership will lapse and your password will stop working.
