Diplomats posted to London are entitled to purchase a vehicle exempt from the UK’s 20% VAT. The process is administered through the FCDO Protocol Directorate. The applicable form depends on where the vehicle was manufactured, a distinction that shapes the administrative process from the outset.
What typically matters early
1
London Diplomatic List status. Appearance on the FCDO’s London Diplomatic List is a prerequisite. Dealers are required to verify status before proceeding. Any discrepancy is typically resolved through the mission’s administrative section.
2
Form classification. Form C428 applies to EEA/EFTA-manufactured vehicles, covering the majority of cases. Form 7 applies to UK-manufactured vehicles. The distinction turns on manufacturing origin, not brand headquarters.
3
Head of Mission authorisation. Both forms require formal Head of Mission authorisation before submission to the FCDO. This step cannot be bypassed or delegated.
4
End-of-posting disposal framework. Disposal of a diplomatically purchased vehicle in the UK requires prior FCDO authorisation via Form 5. Selling without this clearance creates a personal VAT liability.
In short
- VAT relief is 20% of the purchase price; no emissions surcharge equivalent to the French malus
- Two forms apply: Form C428 (EEA/EFTA-manufactured) or Form 7 (UK-manufactured)
- Both require Head of Mission authorisation before FCDO submission
- British nationals and permanent UK residents are excluded, with no exceptions
- Disposal in the UK requires FCDO Form 5 clearance; proceeding without it creates a personal VAT liability
What the relief covers
Relief from VAT on vehicle purchases is governed by the Diplomatic Privileges Act 1964, which incorporates the Vienna Convention into UK law and administered by HMRC’s Diplomatic Privileges team and the FCDO Protocol Directorate. Entitled individuals include accredited diplomatic agents, administrative and technical staff of diplomatic missions and their qualifying dependants.
The relief covers 20% VAT on new vehicle purchases. There is no UK equivalent of the French malus écologique; no emissions-based surcharge applies. The London Diplomatic List, maintained by the FCDO, is the reference document used by dealers and HMRC to verify entitlement.
Second-hand vehicles can be purchased VAT-free only if the seller agrees to supply outside the Second Hand Margin Scheme. Most dealers do not offer this in practice, so the relief applies almost exclusively to new vehicles.
Who qualifies
| Category | Status |
|---|
| Accredited diplomatic agents | Must appear on London Diplomatic List |
| Administrative and technical staff | Must appear on London Diplomatic List |
| Qualifying dependants | Via the entitled diplomat’s status |
| British nationals | Excluded regardless of diplomatic appointment |
| Permanent UK residents | Excluded regardless of diplomatic appointment |
British nationals and permanent British residents are explicitly excluded from diplomatic VAT relief on vehicles, regardless of diplomatic rank, role or employing country. This exclusion is absolute under current HMRC guidance.
The two forms: which one applies
The applicable form depends on where the vehicle was manufactured, not where the brand is headquartered. Manufacturing origin is the determining factor.
Form C428: EEA/EFTA-manufactured vehicles
Applies to most vehicles sold in the UK, covering the majority of mainstream European and Asian brands. The dealer supplies the vehicle VAT-free at the point of sale and retains Form C428 as evidence of a zero-rated supply. VAT relief is applied immediately, with no subsequent refund process.
Form 7: UK-manufactured vehicles
Applies to vehicles actually assembled in the UK. The FCDO forwards the certified Form 7 directly to the dealer. The dealer invoices at the VAT-exclusive price and sends the FCDO a covering letter, two copies of the vehicle invoice and a copy of the diplomatic registration form. The FCDO manages the VAT refund directly to the dealer after delivery.
Where a specific model is manufactured in the UK rather than the EEA/EFTA area, manufacturing origin determines which form applies. The applicable form is established through the dealer before any paperwork is initiated.
How the process typically unfolds
1
London Diplomatic List status
The London Diplomatic List is the reference document used by dealers and HMRC to verify entitlement. Any discrepancy is typically resolved through the mission’s administrative section.
2
Vehicle classification and form identification
The applicable form depends on the vehicle’s manufacturing origin. Dealer familiarity with the diplomatic VAT-free supply process varies; specialist contacts within dealer groups tend to handle the administrative aspects.
3
FCDO form issuance
Forms C428 and Form 7 are obtained through the FCDO Protocol Directorate. Mission administrative sections typically hold an established contact. The FCDO Protocol Directorate is also reachable directly on +44 (0)20 7008 1011.
4
Head of Mission authorisation
Both forms require formal Head of Mission authorisation before submission to the FCDO. This step cannot be bypassed or delegated.
5
FCDO certification
For Form C428: the FCDO certifies and returns it for presentation to the dealer at point of purchase. For Form 7: the FCDO certifies and forwards the original directly to the dealer, then manages the VAT refund after delivery.
6
VAT-relieved purchase sequence
Under Form C428, the dealer supplies the vehicle at the VAT-exclusive price. Under Form 7, the dealer invoices without VAT once the FCDO documentation is in place. The invoice should explicitly show a zero-rated VAT supply.
7
Registration options
Diplomatic vehicles may be registered through the DVLA on standard British plates or on diplomatic plates. Diplomatic plates are not mandatory for all entitled personnel.
Common sources of delay and friction
- Applying the wrong form relative to manufacturing origin
- Missing or incorrect entry on the London Diplomatic List
- Disposal without FCDO Form 5 clearance
- Assumption that British nationality is not a disqualifying factor
End-of-posting disposal requirements
A vehicle purchased under diplomatic privilege cannot be sold freely on the UK open market when the posting ends. Three paths are available.
Export the vehicle
No UK taxes become due on export. Import conditions at the destination are governed by that country’s rules, which vary significantly between posting cities.
Part-exchange with the dealer
Part-exchange with a dealer avoids the FCDO Form 5 disposal procedure. This path is available when a new vehicle is being purchased, typically at the next posting.
Sale in the UK: Form 5 procedure
Prior FCDO authorisation via Form 5 is required. Sale to another entitled diplomat can proceed without VAT or duty. Sale to a non-entitled person triggers VAT and duty calculated on the vehicle’s value at disposal.
Disposal without Form 5 clearance creates a personal liability for the VAT and duty relieved at purchase. The FCDO Protocol Directorate is the relevant authority for all UK disposal procedures.
UK vs France, key differences
| United Kingdom | France |
|---|
| Emissions surcharge | None | Malus écologique, up to €70,000 |
| Relief mechanism | At point of sale (C428) or via refund (Form 7) | At point of sale |
| Status document | London Diplomatic List entry | Titre de Séjour Spécial |
| Forms required | C428 or Form 7 (depends on manufacture) | Form 1 + Form 2 (6 original copies) |
| Nationality exclusion | British nationals excluded | French nationals excluded |

Frequently asked questions
Can diplomats buy a car VAT-free in the UK?
Yes. Accredited diplomats who appear on the FCDO’s London Diplomatic List are entitled to purchase a new vehicle exempt from the UK’s 20% VAT under the Diplomatic Privileges Act 1964.
What is Form C428 and when does it apply?
Form C428 is the VAT relief authorisation form for EEA or EFTA-manufactured vehicles. It applies to most mainstream vehicles manufactured in the EEA or EFTA area. The dealer retains the certified form as evidence of a zero-rated supply and applies the VAT relief at the point of sale.
Do diplomats pay road tax or congestion charges in London?
Diplomatic vehicles registered on diplomatic plates are generally exempt from the London Congestion Charge and the ULEZ. Vehicles on standard British plates are not automatically exempt. The specific position for a given vehicle and registration category is confirmed through the FCDO Protocol Directorate.
What happens when a UK posting ends?
Export to the next posting is the most common disposal route. Part-exchange with a dealer avoids the Form 5 process. Sale within the UK requires prior FCDO Form 5 authorisation.
Are British nationals working as diplomats eligible?
No. British nationals and permanent British residents are explicitly excluded from diplomatic VAT relief on vehicles in the UK, regardless of their diplomatic rank, employing country or London Diplomatic List status.
Is there a limit on how many vehicles can be purchased tax-free in the UK?
HMRC guidance does not specify a fixed numerical limit, but purchases must be for personal use and consistent with genuine needs. Specific circumstances are addressed through the FCDO Protocol Directorate.
