Following star-baritone Tamburini's defection to Covent Garden, Coletti returned to Her Majesty's Theatre, hired by Laporte's successor, Benjamin Lumley.
Lumley chose Verdi's Nabucco "in order to introduce Coletti, who appeared in the part of the maddened king (previously so effectively sustained by Fornasari), and was welcomed with enthusiasm."
Benjamin Lumley was determained to procure the best artists for his theatre.
He had been corresponding with Giuseppe Verdi 
"for the purpose of obtaining from him a work destined for the London boards.
An opera on the subject of "King Lear" had already been promised by Verdi, the principal part being intended for Signor Lablache.
But, on that occasion, the serious illness of the composer had prevented the execution of the design.
Verdi now offered his "Masnadieri", composed upon the subject of Schiller's well-known play, "Die Räuber", and with this proposal I was obliged to close.
On Thursday, July 2, "I Masnadieri" (after wearying rehearsals, conducted by the composer himself), was brought out, with a cast that included Lablache, Gardoni, Coletti, Bouche, and, above all, Jenny Lind, who was to appear for the second time only in her career, in a thoroughly original part composed expressly for her.

The house was filled to overflowing on the night of the first representation.
The opera was given with every appearance of a triumphant success : the composer and all the singers receiving the highest honours.
Indeed, all the artists distinguished themselves in their several parts.
Jenny Lind acted admirably, and sang the airs allotted to her exquisitely."

For Coletti the role creation of Francesco in Verdi's I masnadieri, conducted by Verdi himself, was a personal success: "Coletti's reception by the public on Saturday night had added another laurel to Mr. Lumley's brow, and has given the public increased confidence in all the promises set forth in his so fiercely catechized prospectus.
Never was an opera season so auspiciously commenced.
Verdi had re-written the cabaletta of his aria for Francesco 'Tremate o Miseri' after hearing Coletti's voice.
Coletti remained present in London until 1850, singing diverse roles in the Italian baritone repertoire, performing in Linda di Chamounix, I Puritani, L'elisir d'amore, and most notably the Doge in Verdi's I due Foscari.
In London Coletti created roles in Sigismond Thalberg's  Florinda and Balfe's  I quattro fratelli, as well as the role of Ferdinand in Halévy's La tempesta in 1850.
