Santander is in the market with an RMBS worth £1.1billion ($1.7 billion).
The deal is backed by Alliance and Leicester mortgages and represents the ninth issue of the Fosse Master Trust program.
A pool of first-ranking mortgages secured over properties in England, Scotland, Wales, and Northern Ireland back the notes, which have been assigned a provisional 'AAA' rating by Standard & Poor's.
The bank was last in the market in September with its £2.5 billion RMBS through the Holmes Master Trust program.
