Tillbrook contributed guitar on 1976 demos for punk band The Only Ones.

Following Squeeze's second breakup in 1999, Tilbrook pursued a solo career, often touring around the UK and US in an RV, playing small venues.
He released two solo albums, The Incomplete Glenn Tilbrook and Transatlantic Ping Pong.
Tilbrook co-wrote some of the songs for his solo recordings with artists such as Ron Sexsmith, Chris Braide and Aimee Mann.

In 2006, the film documentary Glenn Tilbrook: One for the Road was released.
It followed Tilbrook on his November 2001 tour across the United States.
In 2007, Tilbrook took time off from his solo career to tour once again with Squeeze who had reformed for the third time.

In April 2007, Tilbrook released The Past Has Been Bottled, the first in a five-disc series of remastered demos.
The first release included early versions of tracks from Squeeze's East Side Story.
The second volume, In The Sky Above, was released in the UK in November 2007, and covered the period from 1993 through 1998.
The third volume, Dreams Are Made of This, was released in November 2009 and covered Squeeze's early years, from 1974 to 1980.
The fourth volume "When Daylight Appears", was released in 2011 and covered the years 1985 to 1991.
The fifth volume, "Upon The Rocks", was released in 2016 and covered the years 1981 to 1984.

In 2008, Tilbrook previewed new material while on tour with the Fluffers, two members of whom are also members of the latest Squeeze line-up.
 A four-track single, "Binga Bong!",
was released in November 2008.
The album Pandemonium Ensues, credited to Glenn Tilbrook and The Fluffers, was released in March 2009.
The 14-track album was produced by Tilbrook and Andrew J. Jones, and mixed by Bob Clearmountain.
 It featured guest appearances from Johnny Depp on "Too Close to the Sun" and Depp's then girlfriend, Vanessa Paradis, on "Interest & Love".

In January 2010 it was announced that Tilbrook and Difford would be spending part of the coming summer in Italy, together writing songs for a new Squeeze album.
The result of this was a 4-song CD of new demo recordings which emerged during their 2012 tour of the US.
The duo toured the UK and US again in 2014-15 with a program they called 'The At Odds Couple'.

In 2014, Tilbrook released a mostly acoustic album titled "Happy Ending".
Later that year, he was featured on the compilation Songs from a Stolen Spring that paired Western musicians with artists from the Arab Spring.
 On the album, Tilbrook's performance of the Bob Marley and Peter Tosh song "Get Up, Stand Up" was meshed with Egyptian singer Dina El Wedidi's "Beyond These Doors".
