I thought that, certainly up to about 1912, the opposite was true of British war planning. The Army had a thoroughly prepared plan to send the BEF to join the right wing of the French, even down to train timetables allowing 10 minute stops for a brew-up. Think Henry Wilson did the Army plan and Arthur Wilson the RN plan, which basically did not exist except for a vague plan to land British troops somewhere that might embarrass the Kaiser - or more likley lead to a swift British defeat and evacuation.
I don't have my sources at the moment, but acknowledge that you have far more knowledge & experience in this theatre, so could you please set me straight?
And Merry Christmas
There are two totally separate planning process. I was describing the Royal Navy planning, which went through War Plans A, A1, B, B1, C, C1, D, D1, and the finally the W1 to W-6 series. The W series had orders for every squadron of ships, so these are the full plans the RN plans to fight with. What you are describing is the British Army war plans which was a separate planning track. And the Army plans is what was executed because if the RN did not get control of the army, the RN lacked the forces need to execute its warplans.

I am working on the assumption that you prefer summaries, so here is some of the details.

The Royal Navy focused on being able to dominate the Baltic Sea. This domination allowed them to apply pressure to either Germany or Russia.
- 1880's. Planning to blockade France.
- By the 1890's, the RN is starting to deal with technology issues making a close blockade tough (torpedo, etc). Still mostly anti-French planning.
- 1902 Exercises practice attacking mouth of Elbe and Kiel Canal Western exit.
- 1903 exercises focused on taking Kiel Canal
- Other plans had main British Fleet within 30 miles of Skaw Denmark or near Laeso Denmark. Basically seizing island of neutrals to use as a base. The plans against France also had the UK violating neutrality by seizing Spanish Islands.
- 1905 Events shift focus. Options include offensive, inshore, and observational blockade of German North Sea and Baltic coasts. Targets switch to Kiel, Kiel Canal, Schleswig Holstein, Helgioland, Wilhemshaven, Cuxhaven, and Baltic entrances. 11 naval division in Baltic, 21 on German North Sea coast.
I can go on for pages like this, but I hope you see the gist. If the Royal Navy plans had been followed, the BEF most likely landing place is Jutland. To keep the Baltic open, then the Royal Navy would be doing offensive operations all up and down the German coast. The Germans knew of these plans, and it is why the expected the Royal Navy to close to the German coast line. It explains why the Germans did not need long ranges on ships. Or good sleeping quarters. They were going to fight the Royal Navy within a half day sail of the German naval bases, maybe much closer. Now when the British Army executed its plan by landing in Flanders, the more popular Royal Navy plans were all invalidated. There were not enough land units to hold either Northern Jutland or to seize islands near the German coast.
And here is where planning matters. The British had also planned a lot of other scenarios. One of these was the distant blockade. This plan was used. Scapa Flow was a base in several intermediate plans, so this portion was used. The Germans, well, they barely had a primary plan, so they did not know what to do with the fleet.
