During the final of the previous series on 24 July 2017, it was confirmed that Love Island would return for a fourth series due to air the following year. It became the fourth series from the current revived format, but sixth series overall. Caroline Flack and Iain Stirling were confirmed to continue their roles as presenter and narrator, respectively. The first 10-second teaser for the new series began airing on 21 April 2018 with a second teaser released on 29 April. A full-length trailer was released on 17 May, which Stephanie Chase of Digital Spy pointed out included "all our favourite lingo from the show". On 23 May, it was confirmed that the series would begin on 4 June on ITV2. On 27 May, it was announced that a new spin-off, "Love Island: The Morning After", had been commissioned for the series. It was hosted by Kem Cetinay and Arielle Free and was a daily podcast that delivered the freshest gossip to the fans. First look pictures of the villa were released on 31 May. The sixteenth episode of the series, first broadcast on 21 June 2018, featured a tribute to series 2 contestant Sophie Gradon, who died on 20 June.
Some of the episodes in this series were aired outside of the usual 9pm timeslot due to the FIFA World Cup.
Angela Jain, the managing director at ITV Studios Entertainment, wanted the series to feature "some surprising cast members", who the audience would not expect to see. She explained that she wanted "enough cast that feels like they are absolutely heart and soul Love Island â and then a certain percentage of people who feel genuinely new to telly and genuinely surprising." When asked whether a former contestant could appear in this series, executive producer Andy Cadman did not rule out anything, but said he struggled to imagine it. The first Islanders for the fourth series were released on 28 May 2018, just one week before the launch. However, throughout the series, more Islanders entered the villa to find love. Niall Aslam's decision to leave the series voluntarily for "personal reasons" marks the first time since the second series where an Islander voluntarily left the show. Niall later said he left because of "stress-induced psychosis." The series was won by Dani Dyer and Jack Fincham having received 79.66% of the final vote.

The couples were chosen shortly after the contestants entered the villa. After all of the girls entered, the boys were asked to choose a girl to pair up with. Alex G was paired with Samira, Eyal with Hayley, Jack Fi and Dani paired up, Niall and Kendall coupled up, and Wes paired up with Laura A. Adam then entered the villa and was told he would be stealing one of the girls the following day.
On 27 June 2017, it was confirmed that âÂÂCasa Amorâ would be reintroduced following its success during the previous series. It is a second villa featuring new Islanders in a twist designed to put the couples to the ultimate test. Twelve new Islanders were introduced during this twist. The villa was called âÂÂCasa Amorâ which translates to âÂÂLove HouseâÂÂ, and is located not far from the main villa. The new Islanders for the twist included six girls; Charlie, Darylle, Ellie, Grace, Kazimir and Savanna, as well as six boys; Alex, Charlie, Dean, Frankie, Jack and Jordan.
The twist came to its conclusion four days later when the original Islanders were given the choice of remaining with their current partner in the opposite villa or couple up with one of the new Islanders. However, as they were living in separate villas, they were not aware of each other's choice. If one decided to re-couple and the other did not, then the one that didn't would be single but still remain on the island. If both re-coupled then they would both remain in the villa with their new partner, and any remaining single new islanders would be dumped. At the end of this, Georgia and Wes became the only single original Islanders, and Charlie W, Dean, Jordan and Savanna were dumped.
The main events in the Love Island villa are summarised in the table below.
