Frequently asked questions
Compatibility often depends on the manufacturer, appliance model and part number rather than the caravan or motorhome make alone. We recommend checking the measurements, specifications and manufacturer references in the product description. If you're unsure, contact our team with your model details or a photo of the existing part, and we'll help you identify the correct replacement.
The vast majority of our spare parts are genuine manufacturer components from trusted brands, including Thetford, Dometic, Truma, Fiamma and AL-KO. Wherever possible, we include manufacturer part numbers and compatibility information to help you identify the correct replacement. We also stock a small selection of compatible and aftermarket parts, which are clearly identified in their product descriptions.
In many cases, yes. If you can't find the replacement part you need, contact us with the manufacturer, model number and any existing part numbers or photographs. We can check availability through our suppliers. We also provide spare parts diagrams and parts lists for a range of caravan and motorhome appliances to help identify individual components.
Orders placed before 2pm Monday to Friday are normally dispatched the same working day, subject to stock availability. We offer Royal Mail Tracked 24 and Tracked 48 delivery, with free standard delivery on orders over £50.
