Bulk tea is a stock-management decision disguised as a bargain. Compare total tea weight, cups per day, storage and live price before letting “400” do all the thinking.
The two-box shortlist
Only PG Tips and Tetley support a live 400-bag comparison in the current shop. Typhoo is not padded into the ranking because its live Original pack is a different size. A short, exact shortlist is more useful than a longer list built from unavailable or mismatched products.
Bag count is not tea weight
Both boxes contain 400 bags, yet PG Tips states 1.16kg and Tetley 1.25kg. That works out at roughly 2.9g and 3.1g per bag respectively from the pack totals. It does not predict which cup you will prefer, but it is a real physical difference that a sticker-price comparison misses.
How long will 400 bags last?
At four cups a day, one box lasts about 100 days; at eight cups, about 50. A small office can move through it quickly, while one occasional drinker may keep it open for more than a year. Estimate real weekday and weekend consumption, then keep most bags sealed while refilling a smaller caddy.
Price can move faster than this guide
Bulk lines can be promoted, repriced or temporarily unavailable. The figures shown are the 8 August shop snapshot, not a permanent claim that one brand is always cheaper. Open both live product pages before ordering and compare delivery economics as well as the box.
Relevant teas from our shop
These are not paid placements. Each 400 bag box shown is in stock now and makes the comparison concrete; it was chosen because its format or flavour answers a separate part of this guide.
PG Tips Original English Breakfast, 400 Tea Bags 1.16kg
The lowest-priced live 400-count box at this snapshot and a straightforward high-turnover PG Tips route.
When we checked on 8 August 2026: £8.00, in stock
Tetley Original English Breakfast, 400 Tea Bags 1.25kg
Also 400 bags, but with 1.25kg stated tea weight versus 1.16kg for the PG Tips box; total weight belongs in the comparison.
When we checked on 8 August 2026: £11.00, in stock
We checked the prices and stock of these 400 bag boxes on 8 August 2026; both can change. At checkout, the 400 bag product page is what counts.
The practical buying decision
- Choose PG Tips if today’s total spend and its familiar blend are your priorities.
- Choose Tetley if you prefer its cup or value the higher stated total tea weight.
- Buy smaller if the box will sit open for months in a warm or steamy cupboard.
- For an office, add a clearly labelled decaf and a caffeine-free herbal option rather than assuming one black tea serves everyone.
Shop the wider shelf and keep reading
Browse PG Tips, Tetley and the full Everyday Tea Bags shelf. The Tea Storage guide matters more with a box this large.
How we keep this guide useful
teas.co.uk both sells these 400 bag teas and edits this guide. No brand paid for inclusion or position. For the 400 bag shortlist we start from teas that our own shop lists and has in stock, then sort comparable boxes by tea family, ingredients, format, caffeine and intended use. Here "best" means the 400 bag box that best fits a stated need, judged within this dated list rather than by a universal tasting.
Range names that hint at an effect are read as labels, not medical evidence. Read the current ingredient, allergen and preparation details on each 400 bag pack. Before choosing a 400 bag box while pregnant, on medicines or with a medical condition, talk to your clinician about liquorice root and similar ingredients. This 400 bag guide was last reviewed on 8 August 2026.
