Shipping & Delivery
Last updated 27 September 2026
Where we deliver
We deliver throughout the United Kingdom, and internationally to destinations where the goods may lawfully be imported. If you are ordering from outside the UK, please read international orders below before you buy.
Cost
[DELIVERY COSTS - e.g. UK standard GBP X, UK tracked GBP Y, free over GBP Z]
The cost is shown at checkout before you pay. There are no charges added afterwards.
Dispatch and delivery times
Orders placed before [CUT-OFF TIME] on a working day are normally dispatched the same day. Orders placed after that, at a weekend or on a bank holiday go out the next working day.
[DELIVERY TIMESCALES - e.g. UK 1-2 working days tracked, international 5-10 working days]
Dispatch begins once your payment has cleared, not when the order is placed. Bank transfers normally clear in seconds, but occasionally a bank holds one for a few minutes. Your confirmation email is the moment the clock starts.
Packaging
Everything is sent in plain, unbranded outer packaging. Nothing on the outside indicates what is inside or who it is from.
Vials are supplied lyophilised and sealed, and are packed to protect them in transit. Where a product needs temperature control, it is packed accordingly.
On arrival. Check the seals are intact and the batch number matches your Certificate of Analysis. Store as described on the product page. If anything looks wrong, contact us before opening it.
Tracking
We email you when your order is dispatched. Where a tracked service is used, that email carries the tracking number. [CARRIER NAME]
Delays and missing parcels
Once a parcel is with the carrier, its progress is largely out of our hands — but chasing it is our job, not yours. If your order has not arrived within the expected window, email support@serenbiolabs.com with your order reference and we will investigate.
Carriers usually require a parcel to be [CARRIER CLAIM WINDOW - commonly 10 working days] overdue before treating it as lost. Once it is, we will replace or refund it.
Please make sure your delivery address is correct at checkout. We cannot redirect a parcel once it has been dispatched, and we cannot refund an order delivered to an address you gave us in error.
International orders
You are the importer. It is your responsibility to check that the goods may lawfully be imported into your country, and to pay any customs duty, import VAT or handling fee your country charges. Those are not included in our prices.
If a parcel is held or destroyed by customs, or refused entry, we cannot refund it. Please check before ordering if you are unsure.
Every parcel is declared accurately on its customs paperwork as research materials. We will not mis-declare contents or value, for any reason.
