This calendar is a snapshot, not a live Electoral Commission feed. Local-government reorganisation can still change who actually polls in 2027.
In this snapshot
- UK parliamentary general elections (last dated poll; next unset until announced).
- English local elections on Watchtower CTYUA / London borough rows, plus GOV.UK cycle years.
- Welsh principal-area local elections (all 22).
- England metro / strategic mayoral elections from the mayors snapshot, linked to /mayors.
- Senedd Cymru ordinary general elections (last 7 May 2026; next ordinary Thursday 2 May 2030).
- Police and Crime Commissioner elections as a last dated poll plus an honest unknown for 2028.
Out of scope
- Scotland and Northern Ireland councils, Holyrood and Stormont (Watchtower geography is England/Wales councils plus UK Parliament).
- Shire district contests that are not Watchtower primary rows.
- Parish / town / community council polls.
- Unscheduled parliamentary or local by-elections (except the sourced Greater Manchester mayoral by-election already in the mayors snapshot).
- Local-authority executive mayors and ceremonial civic mayors.
Unknowns (not invented)
- Next UK general election polling day. Not announced. Latest possible polling day if this Parliament runs full term: 15 August 2029 (Commons Library CDP-2024-0177). That is not treated as the scheduled date.
- Most 2028 and 2029 combined-authority mayoral polling days. GOV.UK factsheets and the England timetable give the year (2028 or 2029) but not the Thursday. Only London (4 May 2028, GLRO paper) and the Cheshire and Warrington / Cumbria first elections (6 May 2027, SI) have a sourced day in the mayors snapshot.
- Next PCC polling day. Electoral Commission has not published a date-specific 2028 timetable. Government has committed to ending the PCC office at the end of current terms in 2028. No 2028 polling day is listed.
- English local-government reorganisation. Commons Library CBP-10494: new unitaries are expected to hold first elections in May 2027. Some existing county/district rows may not be the bodies that actually poll. Open Council Data dates on current CTYUA rows can therefore change.
- Devolution Priority Programme inaugural mayors. Greater Essex, Hampshire and the Solent, Norfolk and Suffolk, and Sussex and Brighton inaugural mayoral contests were postponed to May 2028. They are not sitting mayoral authorities in Watchtower, and no mayor names or exact polling days are invented.
- Devon and Torbay: next mayoral election unavailable. No scheduled first mayoral election is recorded in the sources used for this snapshot.
- Lancashire: next mayoral election unavailable. No first mayoral election date is recorded in the sources used for this snapshot.
- Herefordshire, County of: no next local-election date. Open Council Data councillor file has no Next Election value for this Watchtower row. The date is left unavailable rather than guessed.
