The power that backs Trowbridge Motor Supplies

Being an independent factor is important to TMS, but being part of the United Aftermarket Network gives us the scale to get the quality parts you want at the price you need. UAN's global scale supports the years of local experience in our counter team, a combination with the power to deliver the right parts to you, first time and fast.

United Aftermarket Network

Since it formed in 2004, UAN has grown to become one of the most recognisable names in the UK’s automotive aftermarket. TMS's customers benefit from the combined buying power and additional resources of the UAN, as these allow us to better serve the needs of car & light commercial vehicle repairers, garages, fast fit outlets and body shops around the Trowbridge area.
