Horsebox Builders, Horsebox Repairs, refurbishment and resprays.

At Trevett and Smith Horseboxes we understand your horsebox is a big investment and will carry some of your most prized possessions. Our aim is to build you a horsebox you trust and know will carry both you and your horses comfortably, safely and within the payload permitted.

Our range of horseboxes come with multiple layout options and can incorperate bespoke designs, so give us a call to discuss your needs and ideas for your perfect horsebox or send us a message via the contact page on this website.


Our workshop facilities are ready for horsebox repairs and refurbishment work, so if a new horsebox is not in your budget, refresh your living area or refurbish the horse area or ramp in your current horsebox.


Over recent years we have developed and perfected our builds using Ultra Lightweight Omnia Panel which offers great strength and durability. It also means we can offer a massive class leading payload of up to 1350Kgs on our 3.5t Horsebox Range. These can be uprated to 3.9t giving you 1750 Kgs of payload. We supply you with a weight certificate for all our builds. Feel free to visit our workshops anytime!


All our latest builds are displayed in the image gallery for you to view.
