Container Offices

Secure Stores Nationwide supply top-quality portable site office units for sale across the UK. Our customers include schools, factories and construction firms who need some extra space.

Portable site offices are a flexible, affordable and instantaneous space solution. Like all our welfare units, our site offices are secure, intruder proof and vandal resistant.

Accommodation units

Buying new gives you the chance to tailor-make your site office – to cater to your exact requirements. However, we also stock an extensive range of rigorously inspected secondhand units. These come in a variety of colours and sizes.

Every unit is lined, insulated and fitted with electricity and durable, easy-clean flooring. Plus, every site office comes with a single access 10-point locking door. And they have high-security shutters on every window.

Many customers choose to stack welfare units vertically and we supply specially designed staircases for this purpose. If you intend to do this, get in touch. We’ll advise you and make sure you get the product that’s ideal for you.

As far as options for further customisation go, the list is pretty much endless. Popular additional features include air conditioning, roller shutters, bespoke branding and partition walls. But there are so many more options! Just give us a call and let us know what you’re after. 

Delivering your office

Our network of depots covers every inch of England, Scotland and Wales. Delivery is calculated based on your postcode and for standard units, can take as little as 3-5 days. New units are manufactured to order and will take a little longer.
