The deal launches on 1 August and was brokered between 4Sales and MediaCom.
The idents feature Lucy Alexander, a brand ambassador for Carpetright, sitting on the floor looking at new options for flooring making a joke about how she is "completely floored".
They will be shown around shows including Diy SOS and Homes Under the Hammer.
The spots were created by Everything Different with art direction by Simon Storey and copywriting by Sue Storey. Mark Lediard directed the spot.
Helen Vinken, UK marketing director at Carpetright, said: "It is part of a broader strategy which has included a new brand identity and a focus on communicating our fantastic product range and expert service.
"This sponsorship will run alongside our national TV advertising, press, radio, digital and a ‘Lucy Loves’ campaign which communicates her top product picks via POS in store."
