Refund Policy


Publications can be returned to CIBSE for a refund or exchange providing that:

  • The publication is returned in an unused condition (i.e. the book has not been opened and read), so it can be resold.
  • The publication is returned to us within 28 days from the date on the invoice/receipt. 

In order to arrange a return please contact us at +44 (0)20 8772 3618 or


If a publication is returned for a refund or exchange and CIBSE are not at fault (e.g. the customer has simply changed their mind) then the cost of postage will not be refunded. If the book is returned for an exchange, a new delivery fee may be charged. 


PDFs are free to CIBSE members through the Knowledge Portal* and only non-members should be charged for PDFs. If you are a member and you are charged for a PDF you should not complete the order but instead please contact CIBSE at 0208 772 3618 or

For non-members, a confirmation e-mail is sent with a link which will allow the PDF to be downloaded. If you do not receive this e-mail please contact CIBSE immediately so this can be corrected.  Please ensure that you save the PDF to your computer as the link will eventually expire. Refunds will not be given to customers who lose their PDFs by not saving them.
