Handsome, smart and cocksure, Vincent Swan is head of sales at Cachet Windows and Doors, one of Essex's newly emerging double glazing showrooms.
Formerly an engineer at an oil refinery, an unfortunate 'million pound f*ck-up' led to his dismissal. A chance meeting with an old school friend opens his eyes to the opportunities in double glazing - opportunities that involve ripping off your neighbours for more cash than Vincent has ever dreamt of.
Married to Sam Swan, with two children - Natalie and Robbie - Vincent's talents as a charming, confident salesman translate at home into a fun and impulsive husband and dad. But that energy can just as easily be used for bad behaviour - with a weakness for beautiful women, and an addiction to the thrill of the chase, Vincent frequently puts his seemingly perfect family life at risk.
What drives Vincent Swan is complicated - it's more than money. To be the best? To show the other plebs in this town who's on top? Whatever it is, Vincent's impulses risk making him the architect of his own downfall - but at least it'll be a lot of fun on the way down...
Greedy, immoral, and utterly charmless, Fitzpatrick somehow transforms when there are windows to be sold.
He'll say whatever is needed to close the deal - so, despite his unpleasant demeanour, he's an important part of Cachet's sales team.
Unhappily married to his depressed wife Maureen, Fitzpatrick relishes his time at work, where he can play out his worst desires, and Vincent can't help but oblige.
By all accounts, a lovely man - but Lavender is a hopeless salesman.
He may be university educated and have a sturdy moral backbone, but both those things are about as much use as an aerated condom when it comes to selling windows.
Formally a bassist in Paul Young's band, he joined Cachet moments before the pop star hit the big time. As much as he protests that he's happy to have a regular job - there's a big part of Lavender that yearns to be back on the road again.
Cachet's Brummie receptionist.
Carol is not the sharpest tool in the box. With her massive blonde perm, fondness for the boldest of 80's fashion and ability to say and do the wrong thing at the wrong time, Carol is hard to ignore.
She does, however, have a unique flair for mimicry which on occasion get the Cachet team out of a tight spot.
Headstrong, fiery and assured, Sam Swan is a force to be reckoned with.
A strong mother, who puts her family first, she loves Vincent but is all too aware of his capacity for reckless and thoughtless behaviour.
Sam might admit that this is part of what attracts her to him - but can she keep Vincent in check? Either way, Vincent crosses her at his peril.
