NDAC Servicing      

Price List>

Regular servicing of your scuba equipment is very important to ensure safe, reliable performance and to ensure your expensive kit has a long life. Diving regulators should be serviced at regular intervals depending on time and the amount of use they have. Cylinders have test dates and are subject to regulations, if your cylinder is out of date or in poor condition most air fill stations will refuse to fill it.

NDAC Dive Equipment Servicing

Do you ever wonder why your servicing takes so long to get back from the dive shop – often because it is farmed out to another servicing centre to do the work and that’s why it takes ages for your kit to be returned . . . Well not any more!


The National Diving & Activity Centre has expanded its operation to offer you a far better service, with its own '“in house' servicing and testing station.

The NDAC Servicing Centre is staffed by our own SITA / IDEST and UKAS approved technicians with all technicians holding level three servicing certificates for an extensive range of Scuba equipment.

We have invested in the latest state-of-the-art diagnostic equipment that is available in the UK.

Our in-house technicians, Ashley Bryce & Andy Carver, are second to none and will ensure that your equipment is properly prepared for your underwater adventures before it leaves our servicing centre.


Planning for a dive trip?

We would strongly recommend that you have your dive equipment serviced well in advance of your dive trip or holiday, and that you use it prior to departing on your trip. Regulators in particular can require a final tweak in adjustment to achieve optimum performance – that’s great as we have our very own inland dive site to ensure you are totally 100% happy with your kit and that is has been serviced to your satisfaction and specifications.

Service turn around times - no longer a problem!

Unlike most other servicing centres, NDAC Servicing offers a number of services designed to suit you as the customer. Serviced equipment is normally available for return to the customer within 7 - 10 working days. However, this time may increase if parts are unavailable or if demand for servicing is unusually high during the peak seasons of the dive calendar.

We are therefore offering you the diver, a fast track turn around service. At a small extra cost of £12.00 per item we will be happy to service your SCUABA equipment over night. No more missed dives because your neck seal ripped, or your BDC inflate failed.
