When a helmet goes away for service or a part sits on back order, the cost is rarely the part. It is the shift that does not happen, the spread that stands idle, and the client waiting on a completion date that has already been agreed. Commercial diving is fast paced and time critical, and the gap between a helmet being serviceable and being in a crate is measured in project days.
In short: we are the UK dealer for the Drass D-ONE and an Authorised Maintenance Centre for the UK, appointed by Drass. We supply D-ONE helmets and spare parts directly from stock, carry out specialist servicing through technicians trained at Drass HQ, and run training for owners who want to understand the care and routine maintenance of their own equipment. On stocked items, that means no factory lead time.
What our authorised centre status covers
Drass appointed us as its UK dealer and as an Authorised Maintenance Centre for the UK. The appointment covers three functions, and it is worth separating them because owners tend to need them at different points in the life of a helmet.
| Function | What it means in practice |
|---|---|
| Dealer (supply) | Supply of complete D-ONE helmets, accessories and spare parts, from stock where the item is held. |
| Authorised Maintenance Centre | Specialist servicing and maintenance carried out by our own D-ONE Specialized Technicians. |
| Owner training | Courses we run for owners, covering the equipment, its care and routine maintenance. |
Helmets and spares from stock
We hold D-ONE helmets and spares rather than ordering each one against a customer requirement. Where the item is in stock, you are not waiting on a production slot.
Our D-ONE range covers the consumable and wear items that actually take helmets out of service, alongside complete helmets. That includes the annual repair kit and the maintenance and renewal kit, the soft goods kit, neck dam assembly, side block kit, second stage regulator kit, anode kit, and both pull pin kits, as well as the comfort collar, head cushion assembly, communication mount assembly, camera, light, welding shield and welding lens.
Stock moves, so availability and pricing are confirmed on enquiry rather than published. Contact us and we will tell you what is on the shelf.
Servicing through an authorised centre
Headgear is primary life support equipment, and the examination and certification history behind it outlasts the purchase. Drass supplies both an annual repair kit and a maintenance and renewal kit for the D-ONE, and the interval and the contents of each service are set by the manufacturer’s schedule rather than by us.
Routing D-ONE servicing through an Authorised Maintenance Centre keeps that history intact and keeps the work within the manufacturer’s intended procedure, carried out by technicians Drass has trained and certified on this helmet. Our technical team can discuss your requirements and book your equipment in.
Owner training
Not every maintenance task needs to leave your workshop. We run training for owners covering the equipment itself, its care, and the routine maintenance an owner’s own team can reasonably carry out between services. For dive contractors running several helmets, that is the difference between a planned maintenance system you operate and one you outsource entirely. Contact us for course details and availability.
Trained by Drass, backed by experience
Drass hosted our technicians at its headquarters in Tuscany for hands-on technical and practical training. Chris O’Neill and Ian Roberts completed D-ONE Dealer Training there and are now D-ONE Specialized Technicians. They came back impressed by the build quality and the innovations in the helmet, and by what Drass has in development.
The D-ONE was built around a straightforward design concept, DIVER FIRST, which runs from performance and ergonomics through to ease of maintenance and the technical support behind it. Our technicians bring extensive experience across other diving equipment brands, and combined with their D-ONE training that gives owners support from a team that understands what commercial diving actually demands of a helmet.
Pod configurations
The D-ONE is modular. The pod is removable and interchangeable, so one helmet can be configured for different diving requirements rather than buying a different helmet for each.
| Pod | Application | Status |
|---|---|---|
| Standard (Air) | Air diving. Supplied as standard, easily removed and interchangeable. | Available |
| PLUS | Diving in polluted waters. Configured with a reclaim valve that prevents contact between the valve and polluted water. Coupled with a drysuit and water shroud, the diver is effectively sealed off from the surrounding environment. | Available |
| Rebreather | Saturation diving, intended to meet the requirements of the North Sea and Norwegian oil and gas sector. | In development |

Ready to discuss the D-ONE?
From a first helmet through to ongoing servicing and owner training, we are set up to support D-ONE owners in the UK. We also supply the rest of the dive spread around it, including helmets and full face masks from other manufacturers, and our technician’s service and calibration training supports teams maintaining their own equipment more broadly.
We understand commercial diving is fast paced and time critical, so we pride ourselves on extensive high quality stock, honest and realistic delivery timeframes, and flexible operating procedures across global time zones. We ship worldwide by sea or air freight, door to door. To talk through a requirement, no matter how big or small, call +44 1253 767 788, email info@isubc.com, or request a quote.
