Minimum Order Charge
We do have a minimum order charge of £50 (excluding delivery) for all hires. This is to cover the time involved in organising and dispatching a single small item. Sorry :-(
New clients are required to pay in advance by BACS or credit card. Repeat customers can open a credit account with us on 30 days terms.
Multiple Items & Job Lots
If you're looking to fit out an entire set and need many items, we are happy to quote a discounted rate based on the quantity of items.
The term dry hire means to hire an item without having a technician supplied to support it. Most of our small items are available to dry hire, but some of the more complicated equipment that require specialist knowledge are not. In these cases we will deliver the item(s) personally and set them up for you. Please call us for a quotation based on the hire period and location.
