    UK Shipping: 

    APC Overnight (up to 30kg). The premium Next Day service is upgraded on request to 12 noon delivery / SECURITY / Saturday and various options. We have found APC to be a reliable, courteous and predictable service.


    Europe, EC, and abroad: 

    For every despatch we use a professional broker to organize the fastest and highest quality shippers, and we normally use DHL or UPS depending on territory. Our broker monitors the documentation and Customs Clearance carried out by these two reliable carriers.

    Above 30kg: 

    For UK and overseas we use pallet shipping which is a professional service and avoids risks of mishandling and loss. It is not expensive under our contractors and worth a quote.


    The Music Room enjoys a 40-year tradition of customer care and at time of writing, full 5-star Google reviews. In addition UK customers enjoy the legal rights of mail order and distant selling. 

    We have exported happily for many years and most probably have happy customers in your country who will confirm our reliability and refund in the event of mishaps. 

    Refunds can only be made by the same payment form and to the same account to avoid possible fraud or money laundering.
