The Constituency Tallying Centre, Explained
Updated 2 October 2026.
Late on polling night, a hall in your constituency fills up with sealed ballot boxes, exhausted presiding officers and stacks of paper.
That hall is the constituency tallying centre. Two seats are declared there, and the presidential numbers for the whole constituency are assembled there before they go anywhere else.
What arrives, and in what shape
Each presiding officer travels from their stream to the centre with the sealed ballot boxes, the used and unused ballot papers, the counterfoils, the marked register, the polling station diary, and the completed A forms for all six offices.
The result has already been counted, announced and signed for at the station. Related: where the counting actually happens.
Nothing is recounted at the tallying centre as a matter of routine.
What actually happens to a form when it arrives
The returning officer or a deputy receives the forms and checks them. The check is arithmetical and documentary: is the form complete, is it signed, do the votes cast reconcile against the ballot papers issued, and does the physical form match the copy that was transmitted electronically from the station.
The figures are then entered into the B form for each office. Within a series the A form is filled at the polling station and the B form at the constituency tally, so 35A becomes 35B for the MP seat, 34A becomes 34B for the presidential.
Forms are ordinarily projected or displayed as they are entered, and agents are entitled to be present throughout. A discrepancy is raised there, in the room, while the form and the officer who signed it are both available.
The two declarations made in that room
The constituency returning officer declares the Member of the National Assembly, and each Member of the County Assembly for the wards inside the constituency, and issues the certificates.
That is the moment a constituency gets an MP. It happens in a hall in the constituency, not in Nairobi.
The Governor, Senator and Woman Representative results are county-wide, so the constituency figures feed a county tallying centre where the county returning officer declares them.
What the centre does with the presidential result
It completes Form 34B for the constituency and sends it, with the underlying polling station forms, to the national level.
The constituency is the level at which presidential results are declared in the sense that matters legally, and everything above it is addition. Related: the full journey of a presidential result and what the national centre can and cannot change.
What an agent should be doing in that hall
Not watching a screen.
An agent at a tallying centre should be holding the campaign's own copies of the A forms, collected from every stream, and checking each figure as it is entered against the copy in their hand. That comparison is the entire purpose of being in the room.
Where the two disagree, the agent asks for it to be recorded, in writing, before the entry is finalised. A discrepancy noted at the time is evidence. A discrepancy noticed a week later is an allegation.
Agents are also entitled to sign the B forms and to receive copies of them. Take the copies.
One more thing an agent should be doing is watching for streams that have not arrived. A constituency tally is only complete when every stream is in, and the gap between the forms entered and the streams that exist is a number your agent can work out on the spot if they walked in with the station list. A missing stream at 1am is a question worth asking loudly and early, while it is still a logistics problem rather than a dispute.
What to prepare, starting now
A tallying centre operation is a logistics exercise, and campaigns lose it for logistical reasons rather than political ones.
You need agents in every stream who can get their form copy to your tallying centre agent quickly, which in practice means a photograph sent the moment the count ends. You need one person at the centre whose only job is comparing numbers. You need a way to hold hundreds of station forms in an order somebody can search under pressure at 2am.
That is a system, and it is buildable in 2026 for the cost of some organisation. It is not buildable on the night of 10 August 2027.
Start by writing down every polling station in your constituency and the number of streams each one runs. Everything else is built on that list.
Frequently Asked Questions
Are votes recounted at the constituency tallying centre?
Not as a matter of routine. Votes are counted once, at the polling station, in front of agents. The tallying centre verifies that the forms are complete, signed and reconciled, and adds the station figures into the B forms. A recount happens only where it is specifically ordered.
Which results are declared at the constituency level?
The Member of the National Assembly and the Members of the County Assembly for the wards inside that constituency. Governor, Senator and Woman Representative are county-wide and are declared at a county tallying centre. The constituency completes and transmits its presidential form to the national level.
Can my agent get a copy of Form 34B?
Agents present at the constituency tallying centre are entitled to sign the B forms and to receive copies of them. Those copies, held alongside the A forms collected at each stream, are what allow a campaign to reconstruct and check the whole constituency result independently.
