British passport received but documents not returned

I received the British passport a week ago but my naturalisation certificate and other passport submitted as part of the application have not been returned. Is there a phone number or email address I can contact about this?

Did you pay for secure return of your document? If you haven't then they will be returned by standard post, which is likely to be delayed with Royal mail, given the current crisis and reduction in manpower across various services
