Smart Tachograph 2 Deadlines: Every UK Date Operators Must Know (Corrected, October 2026)

What's changing: Smart Tachograph 2 is now mandatory on every front that matters. Since 24 December 2025, any tachograph fitted to a newly registered in-scope vehicle must be a full smart 2 (transitional units are no longer acceptable). Since 1 July 2026, goods vehicles over 2.5 tonnes used for international hire or reward must have a smart 2 fitted; heavier vehicles were caught by the earlier retrofit dates of 31 December 2024 and 19 August 2025. Since 1 June 2026, zero-emission goods vehicles between 3.5 and 4.25 tonnes are outside the tachograph rules in Great Britain. HGVs on international UK-EU journeys must produce 56 days of tachograph data at roadside checks (up from 28).

Update, October 2026: This article has been corrected and extended. The original version said that all newly registered goods vehicles needed a Smart Tachograph 2 from 24 December 2026. That was wrong. GOV.UK's tachograph guidance and DVSA's approved tachograph centre special notice 01-26 (29 June 2026) both give 24 December 2025 as the date from which any tachograph fitted to a newly registered vehicle must be a full smart 2; between 21 February 2024 and 23 December 2025 a full or transitional smart 2 was acceptable. DVSA reports that some centres were still fitting transitional units after that date, which exposes the operator as well as the centre. We have also added the two 2026 changes: from 1 July 2026 goods vehicles over 2.5 tonnes on international hire-and-reward journeys need a smart tachograph 2 (DVSA special notice 02-26, 26 May 2026, and DVSA bulletin of 1 July 2026), and from 1 June 2026 zero-emission goods vehicles between 3.5 and 4.25 tonnes are outside the assimilated drivers' hours and tachograph rules in Great Britain and move to the Class 7 MOT (SI 2026/501). Dates are as of 12 October 2026.

Every Smart Tachograph 2 date, corrected

The big change: vans over 2.5t now in scope

Historically, tachograph rules applied mainly to vehicles over 3.5 tonnes. From 1 July 2026 the assimilated drivers' hours rules and the Smart Tachograph 2 requirement extend to goods vehicles, or vehicle and trailer combinations, over 2.5 tonnes carrying goods between the UK and the EU for hire or reward, or on own account where driving is the driver's main activity. DVSA's bulletin of 1 July 2026 says the changes do not apply to own-account operators where driving is not the driver's main activity, and DVSA's special notice 02-26 confirms that a vehicle over 2.5 tonnes and under 3.5 tonnes operating only within the UK still needs no tachograph. A van in scope that was first registered on or after 24 December 2025 must have a full smart 2; one registered earlier may be fitted with a transitional smart 2. DVSA warned on 1 July 2026 that installer demand was high and that in-scope journeys could not start until the unit was fitted.

This guide covers the Smart Tachograph 2 rollout deadlines. For the full set of UK tachograph rules, daily and weekly driving limits, breaks, mode switches and record-keeping, see our complete UK guide to tachograph rules.

The 56-day data rule

Since 31 December 2024, HGVs used on international transport journeys between the UK and EU must be able to produce 56 days of tachograph data (including manual records) at roadside checks, up from the previous 28-day requirement. UK-only work stays at the current day plus 28 days. Drivers and operators need to ensure their download and record-keeping routines capture and retain the full 56 days.

What operators must do

1. Audit your fleet: identify which vehicles are affected by each deadline
2. Plan retrofits: book Smart Tachograph 2 installation ahead of 1 July 2026 for international vehicles (installer capacity tightens near deadlines)
3. Update download routines: ensure driver card (28-day) and vehicle unit (56-day) downloads continue, and that 56 days of data is available for international journeys
4. Check newly ordered vehicles: anything registered from 24 December 2025 must have a full Smart Tachograph 2 from the factory. Check the calibration plaque and the installation certificate; DVSA says some centres were still fitting transitional units after that date
5. Review zero-emission vans of 3.5t to 4.25t: since 1 June 2026 they are outside the tachograph rules in Great Britain but must keep GB domestic hours records, and they now take a Class 7 MOT rather than the heavy vehicle test
6. Train drivers on the new tachograph and the 56-day data requirement

Zero-emission vans of 3.5t to 4.25t: out of the tachograph rules from 1 June 2026

The Goods Vehicles (Testing, Drivers' Hours and Tachographs etc.) (Amendment) Regulations 2026 (SI 2026/501) were made on 11 May 2026 and came into force on 1 June 2026. For zero-emission goods vehicles over 3.5 tonnes and up to 4.25 tonnes (including any trailer) used to carry goods for a business, they do three things: exempt the vehicle from the assimilated EU drivers' hours and tachograph rules with no distance limit, so the GB domestic rules and their weekly record sheet apply instead; move the vehicle out of the heavy vehicle (plating and testing) regime into the Class 7 MOT, with the first test at three years rather than one; and apply the 4,250 kg threshold to the tyre rules. The regulations extend to England, Wales and Scotland only. DVSA's special notice 02-26 and the Northern Ireland DVA's notice SN 02-2026 both state that a zero-emission vehicle in this band used on journeys between Great Britain and Northern Ireland still needs a tachograph. A separate exemption continues for gas or electric goods vehicles up to 7.5 tonnes used within 100 km of base.

Why it matters

• Vehicles without the required tachograph cannot legally run the affected journeys
• DVSA roadside enforcement checks the tachograph generation and data
• Operator licence consequences for systemic non-compliance
• Smart Tachograph 2's remote enforcement makes roadside detection faster

How this fits the wider rules

The tachograph generation is only part of compliance, the underlying drivers' hours limits (9h daily, 56h weekly, 4.5h break) and Working Time rules still apply. See our complete tachograph rules guide, operator records guide, and drivers' hours guide.

FAQs

Does the 24 December 2025 date affect my existing vehicles?

No. The 24 December 2025 date (corrected from 2026 in this article) applies to tachographs fitted to newly registered vehicles, which must be full smart 2 units. Existing UK-only vehicles can keep the tachograph originally fitted. Existing vehicles used internationally had to be retrofitted by 31 December 2024 (analogue or digital units) or 19 August 2025 (smart 1 units).

Do UK-only operators need to act?

The 1 July 2026 over-2.5t requirement applies to international hire-or-reward journeys only. UK-only operators need a full Smart Tachograph 2 on any vehicle newly registered since 24 December 2025, and should check that an installer has not fitted a transitional unit.

Does my electric 4.25-tonne van need a tachograph?

Not in Great Britain since 1 June 2026, provided it is zero-emission at the tailpipe and used only in Great Britain. The driver must instead keep GB domestic hours records (a weekly record sheet) and the van moves to the Class 7 MOT. On Great Britain to Northern Ireland journeys a tachograph is still required.

What's the difference between Smart Tachograph 1 and 2?

Smart Tachograph 2 (from August 2023 on new vehicles) adds enhanced anti-tampering, more frequent GNSS position recording, and remote enforcement capability over the first-generation smart tachograph.

How much does a Smart Tachograph 2 retrofit cost?

Typically £400-£700 per vehicle including fitting and calibration. Book early, installer capacity is limited near deadlines.
