The Blues earned a dramatic victory at the Hawthorns thanks to Michy Batshuayi's late goal that has left them seven points clear of second-place Tottenham with two games to play.
The title is theirs as a result, and all that remains is for the trophy to be delivered to Stamford Bridge and the new champions crowned officially in front of their own fans.
Here is everything you need to know about the presentation of the trophy and the Blues' winners' medals ahead of their final two matches of the campaign.
When will Chelsea lift the trophy?
Chelsea will have to wait until the final match of the season to get their hands on silverware, with the trophy presentation saved for the aftermath of their game against Sunderland on Sunday.
They beat Watford 4-3 on Monday night as champions, but the ceremony is usually scheduled as late as possible in order to avoid the improbable but potentially embarrassing situation of a team receiving their medals and then being deducted points before the end of the campaign for some misdemeanour.
That is obviously hugely unlikely to ever occur, but you never know.
Which Chelsea players will receive medals?
Five appearances in the league are needed to claim a medal at the end of the season.
However, special dispensation is given to the role of back-up goalkeeper which means that Asmir Begovic, who made just his second league appearance of the season against Watford, will receive a medal.
Youngsters Ola Aina and Nathan Ake could also receive medals, although only players who have featured in five Premier League games can participate in the official presentation ceremony.
Everyone else in the first-team squad - including John Terry, Ruben Loftus-Cheek, Kurt Zouma, Nathaniel Chalobah and even Oscar, who has since left the club - has played enough to have some metal hanging around their necks at the weekend (or as soon as it lands in his postbox in China, in Oscar's case).
Who will lift the Premier League trophy?
There are a few candidates in the Chelsea dressing room to be the first to lift the Premier League trophy when it is presented after the Sunderland match.
The club captain, of course, is John Terry. Sunday will be his last game at Chelsea and many fans, you would imagine, would love to see him hoist it once last time to say goodbye.
Terry may feel, though, that having made only seven league appearances this season he should leave the honours to the man who has most often worn the armband during the 2016-17 campaign, which is Gary Cahill.
There is probably a good chance, given the respect between the pair, that they will settle for the best of both worlds by standing side by side and lifting the trophy together.
That is assuming, however, that Antonio Conte does not factor in to the equation. Last season, Claudio Ranieri and Wes Morgan grabbed a handle each as Leicester City celebrated their miraculous triumph.
Will Chelsea have a parade?
According to the Daily Mail, the bus will leave out of the west exit at Stamford Bridge and travel east along Fulham Road before turning right onto Hortensia Road. It will then turn right again and head back west on King's Road and New King's Road to Eel Brook Common, where the parade ends.
Fans are advised to line the route at least 30 minutes before it starts due to the expected crowds. They will also be able to watch it on two big screens on New King's Road and at Eel Brook Common, and those staying at home can tune in on Chelsea TV.
