Here is how I do: First I sell all my provinces to France(if it isn't rivaling me), Provence and Britany, gaining 300 ducats and -50 prestige. Then I pick mission Conquer Ayrshire, form alliance with Ulster and Connaught. I set as Denmark, Scotland and Burgundy as my rivals. I assign provinces to the burghers, Yorkshire and Pale and request them to give me 5 heavy ships for free. Then I start fabricating claims in Ireland, priority is Scottish ally there, if he is too far to claim, then Connaught comes handy with its claim when he and Ulster become vassals ASAP.
After you sell provinces on the continent, you start loosing Great power status, plus War of the roses would begin in 1449. (If you're lucky Margaret Anjou stops it).
As soon I got Conaught and Ulster as vassals diplomatically I DOW Irish minor allied to Scotland. In Pale I've built prior to war 6 more units and existing 13 and 14 attack Scotland from the border, on Ayrshire and Lothian. I tend to not move my armies from those provinces whole war, and Scotland doesn't dare to attack. So I use my navy and destroy theirs and blockade Lothian. When Lothian gets occupied i take Ayershire from them, and give irish minor territory to my irish vassal for 0 DIP. Army losses are minimal and I start claiming on other irish minors.
Now WOTR kicks in. Player has several options. Most of the time I take several loans if 28 doomstack of rebels pops and hire mercs as crazy. Another approach is that you pick weaker king in the event and let the rebels enforce their ruler. Third but somewhat gamey option is to place 1 Infantry in each owned British Isles province, because then rebels won't spawn at all and you get to pick York or Lancaster and get -manpower, NO rebels XD
After that I attack the rest of the Irish minors, make sure to tick arrow in DOW menu, so they call everybody, sometimes even Gelre, Hansa, Friesland, Utrecht which are good for subjugate and divert trade to me.
After Ireland is pacified I turn my gaze to the Burgundy, and by that time I have France as ally, because they love me for returning all my continental provinces to them

We attack Burgundy and after several years of war, they are completely occupied and I take all 3 of their subjects for 97%WS(I've unlocked ability with 800 splendor that allows you to transfer subjects in a peace deal for half the cost). During this war I declare subjugation war on Scotland, and France can't kick in because we are busy in fighting with Burgundy

After Scots are defeated and fully occupied, I end the war by taking money and one province near Orkney for CB on Norway(only if Scotland doesn't have CB on Orkney and Shetland. Now I declare war on Norwegian island provinces, land in Sjaeland with my whole army and work my way up to the north, getting 90%WS and taking Norway from them XD
It is important to treat vassals, increase relations, give gifts and influence them, so they won't be rebellious later on. Important thing is to TURN ON SCOUTAGE! That way they are paying more money and aren't called to wars, so when coalition kicks in, they live happily in peace hehe.
OFC, people on the continent are quite displeased by my actions and they form massive coalitions, from Britany to Cyprus, but are no match for English navy consisting of 20 heavies, it could be a bit boring to sit on a island for the whole war, but this is awesome because it's the only to battle massive coalition and win!
For techs I pick Maritime or Innovative first, and Exploration for second idea. I know it's strange, but I like that way. By the 1460ies 99% of trade in English channel is mine thanks to DIVERT TRADE from my dutch vassals, Scotland and Norway and while Ireland is completely subjugated. I save DIP points with smart use of parliament (lower cost of vassal integration - Irish ones, and picking 1TAX increase in 1 province with 5%less construction cost which comes in handy with the Renaissance bonus!)
By 1480 I have DIP tech 7 and 2 Maritime and 3 Exploration ideas, going for Caribean. TRICK for England is to leave other colonisers alone, let Portugal create those Brazil, Mexico, Argentine and African colonies, let him battle with Jolof, Mali etc. I tend to colonize Caribbean, Newfoundland and East coast of America.
There is one silly thing I like to do: make Thirteen Colonies and grant them independence, they form USA and I vassalize them when they are small, that way they fight better, they fight overseas and colonize faster. Now it's time to take all colonies from Spain, Portugal and France, only by using navy!
It is possible to kill or subjugate all the indians in the America by 1500, and feed their lands to your USA vassal.
By 1520, using island jump technique I'm on the conquest of Maldives and the rest of India, having 30 transport ships for there and 50-60k units for the invasion.
TRADE: have merchants from Thirteen Colonies, Newfoundland and Caribbean steer trade to English channel, plus you get one in Ivory coast after the conquest of Portuguese colonies there, plus one from South Africa, plus Zanzibar, IMPORTANT: conquer or vassalise everyone in India, Zanzibar and Gulf of Aden for almost 100% trade going to English Channel.
For idea groups i tend to pick: 1.Maritime/Innovative, 2.Exploration, 3.Innovative/Maritime, 4.Quality, 5. Economic, 6.Trade, 7. Defensive, 8. Offensive/Naval
Hope it helps!
