Tetley Original contains approximately 40-45mg of caffeine per 200ml cup, brewed for 4 minutes from one standard tea bag. That's slightly lower than Yorkshire Tea (50mg) and PG Tips (45-50mg) because the Tetley blend is lighter on Assam. Decaf Tetley sits at 2-3mg. This is the manufacturer quoted figure cross referenced against Which? lab testing.

Why Tetley is lower than Yorkshire

The blend is lighter on Assam. Yorkshire Tea Original is Assam led; Tetley uses a higher proportion of Kenyan and Ceylon, which are slightly lower in caffeine than Assam. The difference is real (~5-10mg per cup) but small enough that most drinkers don't notice in cup by cup tasting.

Brewing changes the number

2-minute brew: ~30mg (under extracted, weaker cup).
4-minute brew (the standard): 40-45mg.
6-minute brew: ~45mg (most caffeine extracted by minute 4; longer mostly extracts tannins).
Stewed in a pot for an hour: similar caffeine to 4-minute brew, but the cup is bitter from over extracted tannins.

Tetley Decaf, the actual numbers

Tetley Decaf uses CO2 decaffeination, removes 95-99% of caffeine. The 2-3mg residual is well below the threshold most caffeine sensitive drinkers can detect. Pregnancy safe, evening friendly, drinkable in volume without sleep impact.
