Lost property

Left something behind? Whether it’s a mobile phone, a set of keys or a trusty old umbrella, we’ll do our very best to get it back to you.

Please note: we will be reducing the hours our lost property office until further notice, as follows:

Opening Hours

Monday to Friday 08:00 to 15:00

We will continue to receive items, process them and contact customers. During this time we will also extend the time that we keep your item.

We’ll get in touch straightaway if we uncover anything that matches the description of your item. And we’ll keep it safe until you can collect it from our City Thameslink station.

You can retrieve lost property anytime from 8.00am until 15:00pm Monday to Friday. A small fee will be payable when collecting your item; the fee depends on the item’s value.

Spread the word

Our trains stop at stations served by other rail companies, too.

Even if you've lost something on board a Great Northern train, it may well end up with another company's Lost Property service. It’s a good idea to report your items to every train company that manages stations along your route.
