The semi-finals were completed in March, but the final was delayed due to building works at the venue, which had been bombed in October 1940.

Walter Donaldson won the title by defeating Fred Davis by 82 frames to 63 in the final, although he reached the winning margin earlier, at 73–49.

[1] The sport was developed in the late 19th century by British Army soldiers stationed in India.

[7][8] Davis had also won the title every year from 1928 to 1940, after which the tournament was not held again until 1946 due to World War II.

[12] The entry fee was five guineas per player, with five per cent of gate receipts to be paid to the BACC.

This was reduced to two guineas, and the same percentage of gate receipts, after representations to the BACC by the Professional Billiard Players Association.

[13] The "Section B" matches were held at Burroughes Hall in London from 2 January to 8 February 1947, all played across 35 frames.

[25] Each player won three frames in the fifth session; McConachy recorded an 85 break, the highest of the match to that point.

[20] Donaldson practised intensively in preparation for the Championship, using a billiard table in a neighbour's attic.

[32] The final, at Leicester Square Hall, was postponed for several weeks due to building works.

[31][41] Donaldson's tactics during the championship involved compiling breaks of around 30 to 50 points, and playing safety rather than attempting difficult pots.

[44] Davis made the highest break of the tournament with a 135 clearance in frame 86 of the final, just one short of the championship record.

[44] In his book Talking Snooker, first published in 1979, Fred Davis reflected that he had probably been "perhaps overconfident" and also had not expected Donaldson's standard to have improved so much as a result of his many hours of practice.

[51] In the last first-round match Kingsley Kennerley won easily against Conrad Stanbury, taking an 18–4 lead on the second evening.

[28] In the semi-finals, Albert Brown secured his place in the last frame of the second day of his match against Barrie, at 18–6,[54] and Kennerley prevailed 18–9 against Leigh.

[55] Brown won the contest of the Birmingham-based players at 18–10, which meant he was scheduled to play Lindrum in the quarter-finals of the main competition.
