Frequently Asked Questions
Everything you need to know about your Thermos UK order and product care.
How long will my Thermos keep my drinks hot or cold?
Performance varies by model, but our vacuum-insulated technology typically keeps liquids hot for up to 12-24 hours and cold for up to 24 hours. Please check the specific product specifications for exact performance ratings.
What is the standard delivery timeframe for UK orders?
Standard delivery usually takes 3-5 working days. We also offer an express shipping option at checkout which typically arrives within 1-2 working days if ordered before our daily cutoff time.
Are Thermos products dishwasher safe?
While some components are top-rack dishwasher safe, we recommend hand-washing the main flask body with warm, soapy water to preserve the vacuum seal and the exterior finish.
What is your return policy for unused items?
We offer a 30-day return policy for all unused items in their original packaging. Please contact our support team to initiate a return and receive a prepaid shipping label if applicable.
Do your products come with a warranty?
Yes, all genuine Thermos UK products come with a limited manufacturer's warranty. Most vacuum-insulated flasks carry a 5-year guarantee against manufacturing defects and thermal performance failure.
Are Thermos products BPA-free?
Yes, all Thermos brand products are BPA-free. We use high-quality 18/8 stainless steel and food-grade plastics to ensure your beverages remain safe and uncontaminated.
