Spiritualized previewed the record live, playing it in its entirety during a show at the Royal Albert Hall on 11 October 2011.

Jason Pierce also stated that the album was partly inspired by the experiences of performing Ladies and Gentlemen We Are Floating in Space live in its entirety.

[8] In 2012 it was awarded a silver certification from the Independent Music Companies Association which indicated sales of at least 20,000 copies throughout Europe.

In a more mixed review, Drowned in Sound's Didz Hammond wrote: "It is, all in all, a pretty solid front half of a Spiritualized album that sort of transmits intermittently in the middle and then totally falls on its arse for the last three tracks.

"[24] Harry Sword of The Quietus gave the album a negative review, writing "Not only does Sweet Heart Sweet Light hit all patented Spiritualized thematic buttons squarely between the eyes – religion, drugs, sickness and redemption – it is also a record that covers everything with a Wyoming sized scoop of full-fat icky sentiment."
