This website is a great place for businesses to place a small static advert. Please message Derelict London via the contact page for further details. I also accept advertising on London's Lost Rivers too.
One square banner and link at the foot of the Derelict London homepage (the same size as, and alongside, the Mitula Property ad)
One rectangular banner and link towards the top of pages (the same size as the Property Renovate ad on homepage)
Header or footer banners the same size (and to replace) the Google Adsense banners on individual pages (please specify)
