We founded Kastt with a simple mission: to take the risk out of buying refurbished tech.

For too long, buying a pre-owned phone felt like a gamble. You’d worry about battery health, hidden faults, or whether the device was even genuine. We are here to change that.

Our Philosophy: Smart, Safe, Sustainable. We believe you shouldn't have to choose between saving money and getting a reliable device. Whether you are buying a brand-new iPhone or a refurbished Samsung Galaxy, we ensure the experience is flawless.

How We Do It: Every refurbished device we sell undergoes a rigorous 70-point diagnostic check by our UK-based technicians. We test everything—from the face ID sensors to the battery life—to ensure it performs like new.

The Safety Net: We are so confident in our quality that we back every device with a 3-Year Warranty.

The Speed: We know you need your tech now. That’s why we offer Next Day Delivery by 1pm via Royal Mail.

The Circular Economy: By buying refurbished or trading in your old device with us, you aren't just saving money—you’re helping to reduce e-waste and keep tech in circulation longer.

We aren’t a faceless warehouse. We are a UK business committed to old-fashioned customer service. If you have a question, need advice, or want to trade in a device, we are here to help.
