The PADI Open Water Diver course is the world’s most popular and recognised scuba diving certification. It has introduced millions of people from around the world to the adventurous diving lifestyle. Once qualified as an open water diver you will have a life-long open water certification that enables you to dive around the world to a maximum depth of 18m. Please read below how we deliver the UK’s best open water courses at our PADI 5-star Instructor Development Centre.

How do you become a qualified PADI diver?

There are 3 steps to becoming a PADI Open Water diver:

  1. Theory – on signing up to the course you will receive your uniue code that allows you to complete all of the theory on a PC, Mac or tablet
  2. Confined water – come to one of our 5 heated pools and learn all of the skills to become a scuba diver
  3. Open water – Once you’ve learned in the pool, then you need to do four open water dives. These are normally done over 2 days. You can complete them with us over a weekend, or at any other PADI centre around the world.

Part A £345 : Theory and Pool

Our Latest Reviews

PADI Open Water Pass Guarantee

Upgrade your course to the Bronze package to include our PASS GUARANTEE. This means that if you do not complete all of the skills or requirements to complete the Open Water Diver course then you can come back as many times as you like until you do pass (subject to availability). Once you’ve completed the PADI Open Water Course, you have learned the basic principles of scuba diving and you are equipped with the knowledge and experience you need to enjoy open water dives.

Open Water Diver Training in Small Group Sizes

Having other people learning to dive at the same time makes your dive experience and scuba training more fun, plus it can help put your mind at ease when others are asking questions too. However, we believe that class sizes should be relatively small so we like to keep them to a maximum of 6 students to 1 scuba instructor, more often than not it is less than this!  You can also request a 1 on 1 or 2 on 1 class. Just call us.

PADI Open Water Diver Certifications and Prerequisites

To enroll in the PADI Open Diver course or Junior Open Water Diver course, you must be 10 years or older and be in reasonable health but you certainly don’t need to be an Olympic athlete.

You will need to be able to swim 200m (any stroke) and float/tread water for 10 minutes. See below for full details.

The Open Water Scuba Gear You’ll Use

During the PADI Open Water scuba certification course, you learn to use full basic scuba diving gear, including a dive computer and standard accessories. If diving in winter then you also use a dry suit to keep you warm and toasty. We use the latest gear from Aqua Lung, one of the worlds top diving manufacturers. All equipment is provided so all you need is your swimwear and a towel but we do recommend that you have your own diving mask & snorkel. If you are interested in purchasing your own equipment then you might find this article useful.

How Long Does it Take?

Theory – this is completed on line and takes in the region of 10-12 hours depending on your ability and how many sessions you break it up in to

Confined water pool skills – For our pools in Caterham, Old Windsor, Brighton & Hove and, Bloxham, all of the pool skills are conducted in an 5-hour single session. Our Tuesday evening Soho pool sessions are 3 Tuesday evenings.

Part B Open water dives – there are 4 dives in total which we normally complete over 2 days. We meet at the lake at 9.30am and aim to finish around 2.30pm or a little later if we light the BBQ and stay around and have a little natter. If you complete the dives overseas (called a Referral) you will need to contact the dive centre there to see how they run it.

The minimum age is 10 years old (in most areas). Student divers who are younger than 15 earn the PADI Junior Open Water Diver certification, which they may upgrade to PADI Open Water Diver certification upon reaching 15. Children under the age of 13 require parent or guardian permission to register for PADI eLearning.

All student divers complete a brief scuba medical questionnaire that asks about medical conditions that could be a problem while diving. If none of these apply, sign the form and you’re ready to start. If any of these apply to you, your doctor must, as a safety precaution, assess the condition as it relates to diving and sign a medical form that confirms you’re fit to dive. In some areas, local laws require all scuba students to consult with a physician before entering the course. Download the scuba medical questionnaire.

Before completing the PADI Open Water Diver course, your instructor will have you demonstrate basic water skills to be sure you’re comfortable in the water, including:

Swim 200 metres/yards (or 300 metres/yards in mask, fins and snorkel) without stopping. There is no time limit for this, and you may use any swimming strokes you want.

Float and tread water for 10 minutes, again using any methods you want.

You can read about our open water course in more detail here.
