Keflavík-born Hólmbert emerged as a stand out player during the 2013 season and his 10 goals were crucial to help Fram Reykjavík avoid relegation from the Icelandic top league. The player also scored three times for the team in the Icelandic Cup, which helped them win the competition for the first time in 24 years. Hólmbert scored Fram's first goal in the Cup final, a 3–3 draw with Stjarnan, then converted his kick as Fram won on a penalty shootout, in a game that he described as "the highlight of my career". The player was known by his teammates as Bertie, and was regarded as having a strong sense of humour.
After trials in the Netherlands with Heracles and in Scotland with Celtic, Hólmbert signed a four-year deal to join the Glasgow giants, for a fee of around £100,000. Although officially signing for the team on 1 January 2014 for the next transfer window, the player started training with his new club at the beginning of December 2013. Hólmbert made the decision to join the Scottish club after speaking to teammates Steven Lennon and Alan Lowing who both played previously in the Scottish Premiership.
Hólmbert joined Danish Superliga club Brøndby on loan in September 2014, after failing to feature in any competitive games for Celtic. During the loan, Hólmbert made eleven league appearances, scoring one goal. After returning to Celtic, he was released on 2 July 2015 without ever making a first team appearance. The same day, it was announced that he was returning to Iceland to play for KR Reykjavík on a 2.5 year contract. On 1 August 2016, he signed for Stjarnan on a loan deal for the remainder of the season. He then made the move permanent after the season.
