Shipping information
Our stock is held at several warehouses located in the UK, Germany and The Netherlands. Our inventory management system aggregates the stock levels in all locations.
Where an item is marked as "ready to be shipped" or "in stock" it means that it is available from one of the warehouses, not necessarily in the UK. Where an item is stocked outside of the UK we will have the item(s) brought over to our UK base and will then ship it to you.
All items are shipped from the UK meaning that the price you see is the price you pay. All import duties and taxes have already been paid by us.
It normally takes 2-3 working days for goods to come in from Europe.
If you are planning on coming to our store for a specific item, please contact us first to ensure it is in UK stock to avoid a wasted journey.
Occasionally, events beyond our control may cause delays.
Returns & warranty
Contact us within 30 days after delivery to return an unused item under our additional returns offer. Conditions apply.
Free tracked UK return labels are available for qualifying parcels under 20 kg and within 61 × 46 × 46 cm.
Your statutory cancellation and faulty-goods rights are unaffected, including for sale items. Any manufacturer’s warranty is additional to those rights.
For the full conditions, refund details and how to return an item, see our returns policy. Contact sales@hogparts.co.uk for help.
