My mistake with 16. 14 is incorrect (though haven't seen that one so it's possible it also works). The rest are correct. The full time of 2001 is of course 2001: A Space Odyssey.

Whoops, missed the page switch. 1984 is correct.

6 Fant4stic Four, 5 Shades of Grey
7 Big Hero 6
10 2 Guns
15 9

Feel like taking a break from trivia (not feeling inspired at the moment) but will come back some time when more energized for that. And of course will participate in others' trivia if I know the answer.
 

I'd forgotten I'd posted this, but given the lack of attempts I assume either there was no interest or else the clues/shows were too obscure. I'll post some additional clues, but if no one makes an attempt at any in the next couple of days I'll assume there's no interest and give the answers. To give people a chance if they are interested, people may also ask one question per show (though not, of course, the title); I'll answer where feasible.

Okay, in that case, here's some UK SF TV trivia questions.

1. In what 1980s TV show did Kenny Baker play an alien disguised as an aspidistra plant?

It was a SF based game show. 

Loki wrote:

2. Being Human was a show about a vampire, a werewolf and a ghost sharing a house together. What was the brief spin-off about their teenage equivalents called?

The title is very similar, literally only a few letters of a difference.

Loki wrote:

3. Who was shown by the Ghost of Christmas Past that if he turned evil his descendent would end up taking over the universe? Surname only is fine.

Several series about this character's family tree, though most included no fantasy elements. 

Loki wrote:

4. What show saw drivers racing one another from London to the north of Scotland through a Britain overrun with zombies?

The show is only a few years old. 

Loki wrote:

5. Name the individual who found a passage back in time to Blitz-era WWII London, and used it as a way to cheat on his wife.

A sitcom, despite the premise. Apparently bigamy facilitated via time travel is hilarious. 

Loki wrote:

6. Name the show that teamed up a famous real-world author of detective fiction with an also famous real-world escapologist as a pair of mismatched crime solvers.

About the most famous examples of each profession as you could think of.

Loki wrote:

7. Name the CBBC show where teenage spies were operating out of an underground base beneath their school.

It helps if you know the names of the two most famous real world spy agencies; the series name is a riff on them.

Loki wrote:

8. According to the theme tune of the series Robin of Sherwood, what was Robin's alias/description?

It's fairly close to what he's normally called.

Loki wrote:

9. Based off a children's book and adapted to TV at least twice, what was the name of a caveman who lived in the modern day at a garbage dump?

**** of the Dump.

Loki wrote:

10. Which crime drama named for its location and previously rooted in macabre but seemingly "normal" murderers in its first three seasons revealed in the fourth and final season that there was a supernatural cause underlying all the bad events in the series?

Named for a region of London infamous for a string of murders.

Loki wrote:

11. A certain artificially-created supernatural being that originated in novels has twice been portrayed on British television by actors previously known for playing sailors (they also have other, possibly more famous roles, but mentioning them just yet would be too big a clue); said actors played the role in the 1980s and in new stories currently being produced, and in both cases the show is named for the character - but which character?

One of the actors was also a Time Lord. The other actor's sailor role was undead, at least initially.

Loki wrote:

12. Name the series set largely in a somewhat supernatural underground society living below London.

Written by a very famous author of fantasy and comics.

Loki wrote:

13. When religious groups complained to Netflix about the TV series Good Omens, demanding it be cancelled, how did Netflix respond and what did Amazon say in return? Exact wording good, but not vital.

It helps to think about which company made Good Omens.

Loki wrote:

14. In what 1950s supernaturally-slanted detective series did one actor who had played both Frankenstein's Monster (iconically) and Fu Manchu arrest as the murderer another actor who would GO ON to iconically play both of those roles?

The latter actor was also very well known for playing Dracula.

Loki wrote:

15. What British children's show did Anthony Head, later star of Buffy the Vampire Slayer, make a guest appearance as a weredog?

The show as a whole was about a much younger weredog; Head was a guest star whose character suffered from the same affliction.
 

3 is correct - Blackadder's Christmas Carol showed how the white sheep of the family was turned bad accidentally by a drunken Ghost of Christmas Past.
6 Yes, those are the two lead characters.
10 Yes. Whitechapel was a British series that started out as a macabre but real world series but in the final season we learned that the devil was seemingly the cause of the region being hit by so many outré events.

11. Frankenstein's Monster/Creature?

Good guess, but no. The Creature was a product of science, and who we are looking for is more a product of the supernatural - I guess you could call them a golem (though they've not been described a such in canon), a being made from an unliving substance in humanoid form, given life by magic. We're talking a less widely known being than the creature, albeit one who has been portrayed on screen at least three times, as well as having their own series of novels (which is where they originated). The second TV version of the character, easily the best known, also had their own comic strips from more than one publisher; one of those publishers was Marvel, who gave the character their own title not once but twice.

12. Neverwhere.

The show used (minor) celebrity contestants rather than the general public. Each week ended with them trying to cross a grid to safety while avoiding an invisible (to them, but not the audience) and moving vortex that would teleport them into deep space if they were unlucky enough to step on it.

The Adventure Game. You can find clips and even the entire first episode on YouTube.

As has been correctly deduced, the two leads were portraying Sir Arthur Conan Doyle and Harry Houdini.

Literally just called: Houdini and Doyle

You're looking for a role played by someone who was the Doctor in Doctor Who, and someone else who was one of the notable pirates in Pirates of the Caribbean.

The character is living scarecrow Worzel Gummidge, First appearing in a string of novels that started in 1936:
First adapted to TV in the BBC's Worzel Gummidge Turns Detective in 1953:
In 1979 Jon Pertwee took up the role. Though better known for Doctor Who

and prior to that best known for a long run in the comedy The Navy Lark (visible pulling a face in the middle of the picture below)
he declared Worzel his favourite role:

Jon played the part through the 1980s. More recently, Mackenzie Crook has taken up the role. He's known for the UK version of The Office

but internationally is better known as one of the undead pirates in the original Pirates of the Caribbean trilogy
 Here's his version of Worzel.

The religious groups complained to Netflix. Netflix wasn't the company making the show. That was Amazon. So Netflix responded:
