I particularly liked 10ac, 14ac, 25ac and 18dn, but I think the clue of the day was 17ac.
Clues are in blue, with definitions underlined. Answers are in BOLD CAPS, then wordplay. (ABC*) means ‘anagram of ABC’, with the anagram indicator in bold italics. Deletions are in {curly brackets}.
Across
1 Disputatious European means to be heard (7)
POLEMIC: POLE (European), MIC{rophone} (means to be heard).
5 Incompetent bishop less arrogant after losing face (7)
BUMBLER: B (bishop), {h}UMBLER.
9 Park-keeper wants good person making deliveries (9)
ROUNDSMAN: {g}ROUNDSMAN.
10 Operator married across the ocean? (5)
MINUS: M (married), IN US (across the Atlantic).
11 Antelope the writer twice brought back (5)
ORIBI: I (the writer), BIRO (another sort of writer), all reversed.
12 Sentence girl’s penned about artistic event (4,5)
LIFE CLASS: LIFE (sentence), LASS (girl), around C (about in the sense of approximation).
14 Rank starter in Indian, cook admits, disadvantages diners (5,9)
CHIEF CONSTABLE: CHEF “admits” I for India, CONS (disadvantages), TABLE (diners).
17 Not out practising golf, say, in the air (4,2,3,5)
HOME ON THE RANGE: HOME (not out), ON THE RANGE (practicing). “Air” in the sense of “song”.
21 Indignant head of state formed an alliance (7,2)
STEAMED UP: S{tate}, TEAMED UP.
23 More confident underwriter drops in (5)
SURER: {in}SURER.
24 Write about boring hanky-panky, lacking skill (5)
INEPT: PEN backwards in IT (that useful Times Crossword euphemism for “hanky-panky”).
25 Hobby of foreign character not long ago (9)
PHILATELY: PHI (a Greek letter), LATELY.
26 Place for treatment, with poor lack of order (7)
ENTROPY: ENT (place for treatment), ROPY (poor). I suppose the Ear, Nose and Throat department has “ENT” over its door, so in that sense is the place to go. I know “entropy” is a thermodynamics concept, but I would hate to have to explain it to a layperson!
27 Settler’s high supporting structure (7)
TRESTLE: (SETTLER*). Delightful anagram indicator!
Down
1 Helper service’s welcoming “Do come again” (6)
PARDON: P.A. (helper), RN (a military service: the Royal Navy) “welcoming” DO.
A potential future crossword champ was looking over my shoulder at this, as I said, “maybe it has DO in R–N” and then “yes – PARDON”. He asked, “where does ‘come again’ fit in?”, to which I of course replied, “pardon?”. “Aha!”, he said.
2 Time to supplant Democrat, quite noisy and uncouth (7)
LOUTISH: replace the “D” in LOUDISH by a “T”.
3 New lad in Rome, a city-dweller (9)
MADRILEÑO: (LAD IN ROME*).
4 Followed orders: catching pet’s involved (11)
COMPLICATED: CAT in COMPLIED.
5 Outlaw putting collar up (3)
BAN: NAB backwards.
6 Note repeated: another is do (5)
MIMIC: MI MI (notes of the Do Re Mi type), then C (a note of the A, B, C type). Novak Djokovic is a great mimic – it’s worth seeing him “do” Rafa Nadal and Maria Sharapova here!
7 Old politician’s absorbed by ancient script (6,1)
LINEAR B: LIB{eral} “absorbing” NEAR (by). I wrote in LINEAR immediately from the definition, then had to grind through the wordplay to see if it was Linear A or Linear B.
8 Person fighting on, one in the habit (8)
RESISTER: RE (on), SISTER (one in a habit). The comma after “on” made it look enticingly like definition, not wordplay. Well done, setter!
13 Digitally depict female earning tip modelling (6-5)
FINGER-PAINT: F (female), (EARNING TIP*).
15 Change terms of contract finally, with organised schedule (9)
TRANSLATE: {contrac}T, RAN (organised), SLATE (schedule – “what’s on your slate today?”). Change terms from French to English, for example.
16 Coat of arms? It’s woven in famous red carpet (8)
CHASTISE: A{rm}S plus (ITS*), all inside CHE (famous communist).
18 Pole embracing female in sheepskin jacket (3,4)
MAE WEST: MAST (pole), “embracing” EWE (female in sheepskin). A lifejacket, of course.
19 In which chap covers part of body? (7)
GARMENT: ARM in GENT.
20 Design lovely, graceful clothes from the south (6)
ARGYLE: backward hidden answer.
22 Police on rounds imitating others (2-3)
ME-TOO: MET (Metropolitan Police), O-O (rounds).
25 Right to leave political group, maybe the end of Labour (3)
PAY: RT removed from PARTY. “End” being “purpose” in the definition.
Of course, I was amused by the golf clue, as you’d have to have a range in your back yard for that. My nephew, who has ten acres, is considering setting one up. Of course, I’d still be a visitor.
I did biff a few, chiefly ENTROPY and CHASTISE, which remained a mystery until coming here. If I had been the blogger, I suppose, I would have managed to figure them out.

Thank you Bruce for explaining the ?? I had against CHASTISE, ORIBI, TRANSLATE and LINEAR B. At one point I became fixated on LIBYAN B, as in the Libyan sybyl.

Luckily my Cretan connections mean I that I have a copy of the Phaistos disc and a book on the disc itself lying around somewhere, whence I originally learned of Linears A and B…
However, it does fit better than the all the other possible words in to E_T_O_Y
thanks for the blog

Had TOY for a long time…
R leaves TORY, leaving TOY… something you might use at the end of labour…
