Alan was the downstairs neighbour of Sue and Ali Osman. He caused nothing but a nuisance for his neighbours such as playing loud music at early hours in the morning and holding unruly parties. The Osmans were left exhausted and irritable from severe lack of sleep. After much pressuring from Sue, Ali was forced to reason with Alan, but Alan refused to take their complaints on board. When the noise continued, the Osmans went down to Alan's flat and threatened to complain to the landlord to make him stop, only to find out that Alan was their landlord and that he'd bought their flat.
Things then proceeded to get infinitely worse for the Osmans with the hands of Alan, when their flat was broken into, and their carpet was defecated on. Ali and Alan had several fights and Alan often resorted to racial insults. During one such argument, Roly, Den Watts' poodle slipped his leash and bit Alan on the arm.
In 1988, Alan managed to patch up his differences with Ali, and he also purchased James Willmott-Brown's house and converted it into flats. He allowed Donna Ludlow to have the first choice of one of the flats in exchange for sex.
In October 1989 Ali was going through some money problems, so as always, he turned to gambling to get himself out of debt. However, he picked the wrong opponent in Alan, and after he had a severe loss and was unable to pay his rent, Alan kicked him out of his flat, which forced Ali to return to Cyprus.
