More than 1,500 bus drivers who operate for Arriva North London have been instructed to take industrial action across a series of dates this summer and autumn after their union said the company had failed to address dangerous working conditions during soaring temperatures.
Why the strikes are happening
Unite has said many of the vehicles used by Arriva have only basic air-cooling systems that reduce interior temperatures by a couple of degrees rather than providing effective air conditioning. The union argues those systems leave drivers and passengers exposed to potentially harmful levels of heat during extended shifts, a problem it says has been raised repeatedly.
“No worker should be made ill by their job. This problem is raised year after year and as the summers get hotter it can no longer be swept under the carpet,”
The comment was made by Unite general secretary Sharon Graham, who said the recent heatwave had exacerbated conditions and increased concern among members. The union also called on Arriva to prioritise remedial measures, describing the issue as a public safety risk.
Planned disruption and dates
Unite confirmed that the action will affect 42 bus routes in and around north London. The union published a sequence of strike periods, with some spanning long stretches of consecutive days. The confirmed dates are:
- Friday 14 August – Saturday 15 August
- Tuesday 18 August – Friday 21 August
- Tuesday 25 August – Friday 28 August
- Friday 4 September – Saturday 5 September
- Monday 7 September – Tuesday 8 September
- Friday 18 September – Saturday 19 September
- Monday 21 September – Tuesday 22 September
- Friday 2 October – Saturday 3 October
- Monday 5 October – Tuesday 6 October
- Friday 16 October – Saturday 17 October
- Monday 19 October – Tuesday 20 October

Local impact and passenger advice
Commuters in north and central parts of the capital should expect cancellations and gaps in service on affected routes during the listed periods. With multiple long strike blocks planned, passengers who rely on these buses for work, school or essential appointments are being urged to seek alternatives in advance.
Transport for London (TfL) usually advises travellers to check live updates on its website and to allow extra time for journeys. Where possible, passengers should consider:
- Using alternative bus routes or services run by other operators
- Switching to rail, Tube or Docklands Light Railway services if available
- Allowing additional travel time and checking for diversions
- Employers and schools planning for staff and pupil absences
What organisers and the company say
Unite has framed the stoppages as a health and safety matter linked to climate-driven hotter summers, pressing Arriva to invest in better cooling or modernisation of its fleet. The union also argues that managers have not taken sufficient steps despite repeated grievances.
Arriva North London has been approached for comment. In previous disputes transport operators have pointed to practical constraints around rolling out full air conditioning across large fleets and highlighted the logistical and financial complexity of retrofitting older vehicles.
Context and consequences
The dispute sits at the intersection of labour rights and public service continuity as the capital navigates more frequent heatwaves. For drivers, the concern is not only comfort but the risk of heat-related illness and impaired ability to perform safety-critical duties. For passengers, prolonged or repeated strike periods mean sustained disruption to daily life and a burden on alternative services already under pressure.
As the first block of strike days approaches, clarity over which specific routes will be suspended and what contingency plans TfL and local operators will deploy will be essential for commuters and businesses across the affected areas.
