Unburdened by ambition or drive, lazy Lee drifts from one ill-advised job to another. His is currently an ice cream van man.

In the first series Lee lived off the goodwill and generosity of his landlady Kate. They started with an easy-going, comfortable friendship however it soon begun to move into un-charted waters when it became apparent they both fancied each other. The problem was Lee couldn't really act on his feelings as Kate used to go out with a guy called Tim... who just happens to be Lee's best mate!

Lee defuses most situations by using jokes - he finds it hard to be serious - a character trait which often gets him into trouble.

When Kate moves back to America Tim puts the flat up for sale - leaving Lee potentially facing homelessness. At first Lee announces he'll buy the flat himself however his inability to earn a steady income means he eventually ends up renting the spare room from the new owner - Tim's younger sister Lucy.

It isn't long before Lee finds he has feelings for his new landlady too, she is after all quite attractive. Once again there are barriers in the way of Lee having a potential relationship though - in this case it is the fact that Lucy already has a boyfriend, the rich and suave Guy. Lee doesn't make much of an attempt to hide what he thinks of Guy - taking the mickey out of his age soon becomes a funny hobby for Lee.

Tim is Lee's best mate. He's rather uptight and, despite the fact it's been ages now since he split up with Kate, he is still struggling to get over the break up.

Before Kate moved back to America, Tim used to do everything he could to continue to see her. He'd often turn up at the flat with a rubbish excuse for being there. He even tried to get Kate back by inviting her to his Grandma's funeral in a hope she'd feel sorry for him!

Tim works as an accountant for the local council. He is not what you would call a risk-taker or a party animal. He has made one big mistake though - having a brief romantic encounter with a girl quite a bit younger than he is - it's something Lee and Kate are un-likely to ever let him forget.

Now that his best mate Lee is living with his 'little sister', Tim has something new to worry about: it doesn't take long before he becomes suspicious about what his best friend's feelings are in regards to his sibling.

Lucy has been in Zurich working as a successful business women. Upon returning to England she buys the flat and reluctantly rents out the spare room to Lee.

Lucy is very career-minded. She is a young, confident, successful go-getter. As a result there is a lot of tension between Lucy and her brother Tim - he's jealous of her whilst she thinks he's an underachiever. Much of the sibling-rivaly stems from the fact that Lucy is the favourite sibling with their mum and dad, whilst Tim is looked upon as a disappointment.

Lucy is currently going out with Guy - her boss and a man 20 years her senior. Despite the fact she is dating Guy there is clearly some romantic tension between her and Lee when they are in the same room. At the end of the second series Lucy and Guy split - does this mean Lee now has a chance?

Guy is a successful, sophisticated fiftysomething entrepreneur. First seen in episode two of series two, Guy is Lucy's new boss and soon becomes her new boyfriend too. It emerges later in the series that amongst Guy's business interests is a lap-dancing club.

Due to a mis-understanding Lucy initially thought Guy was gay, however she was clearly attracted to him even then and attempted to 'turn him straight'. When it transpires that Guy is actually straight and fancied her it wasn't long before they were locking lips.

Lee and Guy are unlikely to ever get on. They share nothing in common and the fact that Guy dominates life in the flat and gets to kiss the lady he loves clearly bugs Lee. As a result Lee makes jokes about how much older Guy is than the rest of them - particularly his girlfriend - at every opportunity he can and tries to find ways to dis-credit him (for example breaking into his office to try and find evidence he is a gangster).

Kind and generous, Kate was Lee's landlady in the first series. She was more than just a rent collector though... she was determined to push Lee into making something of his life.

Kate is from California and so, like a lot of people from that region of America, pays a lot of attention to her health. She was continually trying to coax Lee into eating some of her disgustingly-healthy homemade food.

Despite the fact Kate's personality is quite different from Lee's they still found themselves attracted to each other. The trouble was she also sometimes found herself wondering whether breaking up with Tim was such a great idea!

Kate has now moved back to America.
