Diving in the UK is often a cold and challenging affair. There are interesting wrecks and marine environments all around its convoluted coast and many islands, the standout being the scuttled German Imperial Fleet in Scapa Flow, in the Orkney Islands.
British diving is like Longfellow's Matilda: when it's good, it's very very good . . . and then there's the other 360 days of the year. Its main limitations are first, that it's often cold and dark, so you need a dry suit; second, it's organised around club diving, with groups organising their own boat and equipment, it lacks the kind of resort dive shacks where you show up with little more than a credit card and within the hour you're on the water. These two are linked because a dry suit has to fit just so, else the neck seal either garottes you or lets in gouts of cold water. It's not practical to hire one off the shelf, and you must have training in how to use it, with try-outs in the pool and at an inland site before going out to sea. You can get away with wearing a wet suit provided a) it's a chunky toasty affair, say a two-piece 7 mm semidry, and b) the water is relatively warm, ie summer and not particularly deep or extended dive time, and c) you only do the one dive then change and get warm. Coming up with blue lips from Dive One and shivering through a surface interval is not a good prelude to Dive Two. It's worth noting that in British diving, it's not the water temperature that's the problem, but the surface conditions. In the south-west, water temps tend to range from 16c in late summer to 9c in late winter/early spring. However, surface conditions are invariably chilling, with strong winds and temperatures in single digits in winter, and rarely exceeding the low-mid 20s, even in summer, while British dive boats rarely offer much, if any, shelter. Diving is often from rigid hull inflatable boats, or small fibreglass affairs with little except a small cabin for the coxswain and maybe an electric jug for making hot drinks. The fact thats operators will typically proudly advertise the fact they have a head (toilet) on board, if they do, says a lot. That said, a day with two summer shore dives in Cornwall, with 40-45min runtimes in <20m can be achieved in comfort with a high quality semi-dry suit, especially if one comes prepared with a windproof and a thermos.If temperate rocky reefs and wrecks are your thing, you will be richly rewarded.... provided the weather holds out.
British waters have a big tidal range: 5 m is not unusual. This generates stiff currents, so dive plans are intricately planned to hit slack water, or planned as drifts. Boats ramps, piers and shore-diving locations dry out at low tide, and depth computations also need to factor in the height of the tide. The Gulf Stream means that, while places on the same latitude are ice-bound, British waters are diveable in winter in calm periods, with winter waters in the south-west generally in the 9c range, while Scotland tends to be a few degrees colder, around 6 to 7c. Nowhere in the UK has sea-ice in the winter, though inland freshwater sites may get a layer of ice during colder winters. The predominant weather system is from the Atlantic: southwesterly, mild and wet, often with depressions generating gales; spells of nor'easterly weather can also blow you out. They tend to bring cold, dry weather.
Much diving in the UK is onto wrecks, the legacy of a country that traded worldwide by sea, and the many casualties of war. There is protective legislation for many, especially of wartime wrecks that still hold the remains of those who lost their lives. Lifting of any artifact from the sea-bed, when allowed at all, must be declared to the "Receiver of Wreck" who will determine its disposition. By and large, the best diving in found in Cornwall, the south-west coast of England, Pembrokeshire in Wales, and the west coast of Scotland, all of which features extensive temperate rocky reefs with a wide variety of life. Visbility on these coasts is variable, and within days can go from "excellent" to "atrocious" if the winds change. The east coast is generally dominated by sand and mud, with low visibility, colder temperatures (being blocked from the full force of the gulf-stream) and a lack of a rocky reef systems to harbour life, though a few sites, such as the Farne Islands, do break the trend. There are many inland sites in lakes, quarries and gravel lagoons, and cave diving in limestone regions.
The main training agency in UK is BSAC, though PADI certification is widely available. If you're here for an extended period, eg at university, by all means get involved with your college dive club and get trained. This will take several weeks and you'll probably do your first few open-water dives in a chilly quarry. But nowadays most Brits train in warm climates then decide whether they want to brave their cold home seas (and mostly decide against). You'd be mad to travel to Britain for the purpose of initial training. The Bible New Testament describes how a madman was cured by driving out his demons to enter a herd of pigs, who plunged over a cliff into the Sea of Galilee (Mark 5:1-20, Matthew 8:28-34, Luke 8:26-39). If those pigs had instead done the traditional British diver training course, they'd be just about qualified by now.
Starting at the northern tip of the country, because Scapa Flow in the Orkney Islands is probably the only dive area for which you'd make a special trip to the UK. When Germany surrendered at the end of World War One, its fleet was disarmed and brought to this enclosed reach of sea. Peace negotiations dragged on and Admiral Reuter believed the British would seize the fleet for their own purposes, so he had them all scuttled. Many were later salvaged, but seven big ships remain (in about 30 m depth) and are regularly dived. They've been there for a century and are fragile but still impressive. Orkney also has shallower wrecks and reefs, eg along the "Churchill barrier", the causeway that links several islands.
Continuing clockwise, the northeast coast is scenic, rocky and often suitable for shore diving, especially around the Scottish / English border. Areas include the villages of Dunbar and St Abbs, and further out lie the Farne Islands of Northumberland. To the south, coastal conditions aren't so good, and you have to venture some miles offshore, eg to the wreck of the Polish liner Piłsudski off the Humber estuary. Much of the east coast is dominated by sand and muddy shallow seabed, with few features to provide havens for life, and low visibility, as a number of major rivers drain into the North Sea, including the Thames and Humber.
The English Channel is littered with wrecks. Sites (east to west) include: Chesil Cove and Portland Bill in Dorset, Swanage Pier in Dorset, Fort Bovisand in Devon, the Eddystone Rocks off Plymouth in Cornwall, The Manacles rocks off the Lizard Peninsula of Cornwall, and the archipelago of the Isles of Scilly. The further west along the coast one goes, the better conditions become. From Swanage westwards, the toopgrahy of the seabed becoems increasingly dominated by rocky reefs, and visbility and variety of life improves. Around Cornwall, basking sharks, blue sharks and seals can be found, as well as ocassional exotic visitors such as Mola-Mola (Sunfish). Key sites here are Swanage Pier (a simple shore dive that's very popular with macro photographers), Brixham, Falmouth, and the Lizard.
The Bristol Channel lies between Cornwall and Wales, its premier site being the protected island of Lundy. Much of South Wales is industrial, till you reach the attractive peninsula of Pembrokeshire, eg Martin's Haven. There's another area around the islands of Anglesey and Holy Island.
Further north, there's a lot of river run-off (eg from the Mersey) and the west coast sites are exposed to the weather. There's not much until you get into the Firth of Clyde, with many wrecks, and on Arran the protected area of Lamlash Bay. The seas around the Hebrides are clear of run-off and, whilst often wild, there may be shelter between the islands; the Sound of Mull being a popular example. You will be very lucky if conditions allow a trip out to lonely St Kilda, 40 miles out in the Atlantic, though visibility here can be spectacular.
Northern Ireland and the Isle of Man have diving similar to the Hebrides.
UK inland dive sites are in flooded quarries and lakes. They're generally only dived for training / refreshers, testing kit, or if bad weather has blown out a sea trip. Most dive clubs are within 30 mins drive of their local "muddy puddle". Some bigger centres worth a longer drive include Stoney Cove between Leicester and Coventry, the National Diving and Activity Centre at Chepstow, and Capernwray near Carnforth.
Cave diving (including in old mine workings) in Britain is considered a technique of caving, not a specialty within diving, so it's not covered here. Enough to say that you need to be very good indeed at what you're doing; several of the divers in the Tham Luang cave rescue of 2018 were British.
The UK has a large number of dive sites, both inland and coastal, and many of these are wreck dives. The inland dives include a number of lakes, quarries and caves.
This section covers natural marine sites, and also built structures such as piers. Any wrecks there are described in a later section.
Chesil Cove from West CliffChesil Cove is a shoreline dive site in Dorset, England. Location: The most southerly part of the 18-mile (29 km) long Chesil Beach Access: Shore dive Most dives will not exceed 10 to 15m. Topography: Beach shoreline Ecology: South coast marine life, including nudibranch, dogfish, spider crabs, lobster, cuttle fish, pipefish and John Dory.

The Eddystone, with current lighthouse and stub of previous towerThe Eddystone, (also known as Eddystone Rocks) is an offshore rocky reef dive site in Cornwall Location: A seaswept group of rocks some 9 miles (14 kilometres) south west of Rame Head Access: Day boat. Topography: Gneissic outcrop of the Cornubian batholith supporting one of the world's iconic lighthouses. Hazards: Can get very rough.
Inner Farne and its lighthouse.The Farne Islands is an offshore dive site in a group of islands off the coast of Northumberland, England Topography: There are between 15 and 20 islands and several tidal rocks from 2.5 to 7.5 km from the mainland, The main islands in the Inner Group are Inner Farne, Knoxes Reef and the East and West Wideopens, which are all connected at very low tide, and the Megstone a bit further away. The Outer Group, beyond Staple Sound, comprises Staple Island, the Brownsman, North and South Wamses, Big Harcar and the Longstone. The Farnes are Dolerite outcrops, which forms resistant columns, giving the islands their steep cliffs, and the stacks scattered around the sea around the islands. Many of the small islands are bare rock, but the larger islands have a layer of soil supporting vegetation. The strata slope slightly down to the north, so the highest cliffs are to the south and some beaches to the north. Ecology: Birds and seals. Some sites may provide an opportunity to combine diving and bird watching — at the Pinnacles, Guillemots may be seen fishing at safety stop depth. Features: Wrecks: Wreck of the Danish steamer Chris Christenson, close to the reef off the south tip of Longstone, Outer Farnes in about 30-35m at N55°38.397' W001°36.182' Wreck of the German SS Abessinia, at Knifestone, Outer Farnes, at N55°38.9' W001°36.12', in 9-20m of water. Wreck of the British cargo and passenger steamer Brittania, on the Callers, Outer Farnes. Wreck of the French steamship St Andre at Staple island.

Map of the scuttled German ships at Scapa FlowScapa Flow is a dive site in a body of water in the Orkney Islands, Scotland, United Kingdom, sheltered by the islands of Mainland, Graemsay, Burray, South Ronaldsay and Hoy. Location: Access: As of 2010, at least twelve "live aboard" boats—mostly converted trawlers with bunk rooms in their former holds—take recreational divers out to the main sites, primarily from the main harbour at Stromness. Maximum depth at the site is The wrecks are mostly at bottom depths of 35 to 50 m.. Visibility is likely to be very variable, from 2 to 20 m, and water temperature The water is cold Topography: Scapa flow has an area of about 312 km2. It has a sand bottom with maximum depth of about 60 m, but mostly about 30 m, and is one of the great natural harbours of the world. Features: There are very few sites which can offer such an abundance of large, historic wrecks lying in close proximity and shallow, relatively benign diving conditions. The wreckage of the remaining seven ships of the German fleet and some other sites such as the blockships is regularly listed in dive magazines and internet forums among the top dive sites in the UK, Europe, and even the world. The wrecks include: The three sister battleships of the König class, the SMS König, SMS Kronprinz and SMS Markgraf lie upside down with around 25m of water over them. They are impressive dives, because of their large size. The four light cruisers SMS Dresden, SMS Karlsruhe, SMS Brummer, and SMS Cöln lie on their sides with around 16–20 metres of water over them. With the exception of the shallower Karlsruhe, they have been less heavily salvaged than the battleships and are much more accessible for divers. Additional sites of interest include the destroyer V 83, which was raised and used as a working boat during salvage operations, and later abandoned; the Churchill blockships, such as the Tabarka, the Gobernador Bories, and the Doyle in Burra Sound; the U-boat UB 116; and the trawler James Barrie. Hazards: It is possible to enter a wreck inadvertently in poor visibility and light. This could be disastrous if you can't find your way out again. Recommended equipment: A surface marker buoy will provide a guideline to the surface in conditions of poor visibility, which mitigates the risk of getting lost inside a wreck after unintentionally entering in the dark. Permits: Divers must first obtain a permit from the Island Harbour Authorities, which is available through diving shops and centres. Divers are permitted to enter the wrecks, but not to retrieve artefacts located within 100 metres of any wreck. However, broken pieces of ships' pottery and glass bottles have been washed into shallow waters and onto beaches. The wrecks of HMS Royal Oak and the dreadnought HMS Vanguard, which exploded at anchor during the First World War, are war graves protected under the Protection of Military Remains Act 1986. Only divers of the British armed forces are permitted to visit them.Scapa Flow was the United Kingdom's main naval base during World War I and World War II, but was closed in 1956.

Visibility is likely to be The sea around the village is unusually clear, in contrast to the more silt-laden coastal waters further to the north or south. Features: The double archway at "Cathedral Rock" is just 50 metres from the shore. Special skills required: This is a popular site for trainees to do initial sea dives. These clear waters and the spectacular underwater scenery resulted in Britain's first Voluntary Marine Reserve being established at St. Abbs. Several small, nearby rocky islands, such as "Big Green Carr", "Broad Craig" and "Little Carr" are near to the harbour and easily can be circumnavigated underwater.

Wast Water seen from the summit of Great Gable, 4.5 km to the NE.Wast Water, (also known as Wastwater) is a lake dive site Location: in Wasdale valley in the western part of the Lake District National Park Maximum depth at the site is 79 metres (258 feet). Visibility is likely to be quite clear at the bottom, but there's nothing much to see. Topography: The lake is approximately 4.6 kilometres long and 600 metres wide and is the deepest lake in England. It is a glacially 'over-deepened' valley. The surface of the lake is about 60 m above sea level, while its bottom is over 15 m below sea level. Features: A "gnome garden" complete with picket fence was placed in the lake at 48 m as a point of interest for divers to explore. It was removed from the bottom of Wastwater by police divers after three divers died in the late 1990s, but it is rumoured that the garden has been replaced at a depth greater than 50 m, which is the limit beyond which the police are not allowed to dive Hazards: No site specific hazards reported Recommended equipment: equipment appropriate to the dive plan. Special skills required: skills appropriate to the planned depth of dive and equipment to be used. Owned by the National Trust.
Several wrecks are archaeological sites or war graves - if diving is permitted at all, it's "look but don't touch".
Artifacts taken from the seabed must be promptly declared to the "Receiver of Wreck" - yes, this is nowadays online, with no tricorn hats involved.
Don't pilfer crabs or lobsters from fishermen's pots, or raise suspicion that your legitimate catch came from there. It's a sure way to get the harbour barred to divers.
Your first urgent call at sea should be to the Coastguard on VHF channel 16, 156.800 MHz. They're also reached by 999 by landline or mobile. They can coordinate response by other vessels (not just the lifeboat), by helicopter and landside. This includes pan-pan-pan incidents: the tanker as yet invisible over the murky horizon can just about miss your drifting RIB if it starts altering course immediately.
Medical assistance should be sought through the standard NHS: "treat the patient, not the bend". Especially around popular diving areas, responders are used to incidents and have a nose for what's likely to be decompression sickness or sea-sickness or heart attack or whatever. If they seem obtuse, you could call +44 1224 681818 in Scotland or +44 7831 151523 in the rest of the UK, or the DAN international number +1 919 684 9111. There are four categories of receiving centres for UK diving casualties and it helps to land first time in the correct one, so never go haring away towards a hyperbaric facility without a prior conversation with a specialist.
First ask a local diver: it's astonishing what spares and tools they routinely carry. You could probably construct a large artificial shipwreck with what's in the car trunks near a popular site.
But one reason they do so is the limited back-up. Centres live or die by how much new stuff they can sell; they may have limited in-shop repair capacity, sending stuff away for repair or ordering parts as required. A dive shop in Glasgow, closed Sunday, is little help when you've ripped your arm cuff in Ullapool. Centres may put on excursions and training courses but aren't in the business of organising dives for passers-by. And where can you get an air fill - and on Saturday evening? So you need to look ahead, a standard online search will do, though again the local divers and skippers will know what's possible.
And as noted at the outset, the UK is not a diving scene where you just saunter up with log book and credit card, hire equipment, and get on the boat. Shops sell not rent. There are free-standing boat operators but they may be booked out to clubs with no room for extras. Always plan ahead; if only you could do so with the British weather.
Many ferries and road tunnels (eg A19 Tyne tunnel) ban "hazardous materials". This really should not include divers' tanks - breathing gas pressurised up to 230 bars is specifically exempt from HSE regulations - but companies are idiosyncratic. Having to empty all your air tanks is not a good start to a dive trip, especially as you watch all the RVs with campergas and spare fuel being waved aboard. So check ahead on the company website.
