The whole 2026 private hire VAT story rests on one distinction in VAT law: principal versus agent. If an operator supplies the journey to the passenger as principal, the fare is the operator's taxable supply and VAT bites on the fare at operator level. If the operator merely acts as agent, introducing the passenger to a self-employed driver who actually supplies the journey, then the driver is the supplier and VAT depends on the driver's own turnover. This piece is part of [the 2026 Private Hire VAT changes hub](/insights/private-hire-vat-changes-january-2026/).
That single question explains why London diverges from the rest of the UK, and why the answer to "do I have to charge VAT" can differ between two drivers doing the same job in different cities.

Principal and agent defined for VAT
In VAT terms, a principal makes the supply in its own right: it contracts with the customer to provide the goods or service and is responsible for VAT on that supply. An agent acts on behalf of another party, arranging a supply between a principal and a customer, and is generally only liable for VAT on its agency commission, not on the underlying supply. The label a contract uses is not decisive; HMRC and the courts look at the economic and contractual reality of who is doing what.
Why London is the principal case
London private hire licensing, under the Private Hire Vehicles (London) Act 1998 and the High Court ruling in Uber London Ltd v Transport for London (2021), requires the licensed operator to contract with the passenger to provide the journey. Once the operator is the contracting party for the supply, it is the principal, and the fare is its standard-rated supply. That is the legal route by which London fares ended up carrying 20% VAT at operator level from January 2026.
The point worth stressing is that this came from licensing law, not from a tax authority preference. The licensing requirement shaped the contract, and the VAT treatment followed the contract.
Why the rest of the UK is more mixed
Outside London, private hire is licensed under the Local Government (Miscellaneous Provisions) Act 1976 and administered by individual local authorities, with a different statutory framework from the London regime. The contractual structures operators use can differ region by region and operator by operator. Some structures look more like genuine agency, with the driver as the supplier of the journey; others look more like principal supply. The result is a patchwork rather than a single national rule.
This is why a Manchester or Birmingham multi-app driver cannot simply assume the London answer applies. The right question is always: under my actual contracts, who is the principal supplier of each journey?
The litigation backdrop
A series of cases tested whether non-London operators must, like London operators, contract as principal with passengers. Uber Britannia Ltd brought proceedings seeking clarity on the position for operators outside London, and the wider sector, including the structures used by operators such as Bolt and FreeNow, was watched closely because the answer drives the VAT outcome. Drivers should treat the legal position outside London as developing and operator-specific rather than uniformly settled, and should rely on their own contracts and professional advice rather than headlines.
How Uber changed its approach
The practical effect of the London ruling was that Uber, to operate lawfully in London, moved to contracting with passengers as principal for London journeys. Outside London, the appropriate contractual structure has been the subject of litigation and operator decisions rather than a single forced model. The headline "Uber changed the rules outside London" should be read carefully: what changed is the legal scrutiny of whether non-London operators must also be principals, and the contractual choices operators have made in response. The detail varies, and a driver's own agreement is the authority for their situation.
What it means for a driver in practice
- If you drive London-only under a principal-model operator, the operator carries the fare VAT and your sub-threshold turnover does not trigger personal registration from this alone.
- If you drive outside London under a genuine agency structure, you may be the supplier of the journey, which puts your own turnover in the frame for the £90,000 test.
- If you drive across multiple operators and regions, you may face a blend, and you need to identify which fares are agency-structure income.
- The contract label is not the final word; the economic reality of who supplies the journey governs.
- When in doubt, get the position confirmed against your actual operator agreements before assuming you must, or must not, register.
A worked comparison
Consider two drivers each grossing £80,000 of fares a year. Driver A drives London-only under a principal-model operator. The operator accounts for VAT on the fares; Driver A is below £90,000 of their own turnover and is not required to register. Driver B drives outside London under a genuine agency structure, so Driver B is the supplier of the journeys. Driver B is also below £90,000, so still not required to register, but Driver B is the one whose turnover is being measured against the threshold. The difference only becomes a live VAT registration question for Driver B as their turnover approaches £90,000.
Now raise both to £95,000 of fares. Driver A, in the principal model, still does not register personally because the fares are the operator's supply. Driver B, in the agency model, is the supplier and crosses the threshold on their own turnover, so Driver B must consider registration. Same gross fares, different VAT outcomes, driven entirely by the principal-versus-agent structure.
The danger of over-generalising
It is wrong to tell every UK private hire driver "you must now charge 20% VAT", and equally wrong to tell every driver "VAT never affects you". The honest position is that it depends on the contractual structure under which you drive and on your own turnover. London principal-model drivers are largely insulated at the personal level; agency-model drivers outside London need to watch their own threshold. Anyone selling a one-size-fits-all answer is oversimplifying a genuinely structure-dependent question.
Multi-app and mixed-structure drivers
A driver running Uber, Bolt, and FreeNow across a region may have different contractual structures with each operator. For VAT, what matters is the total taxable turnover of supplies the driver makes as principal. If some of those app structures make the driver the supplier, that income counts toward the driver's own £90,000 threshold; income under a true principal-operator model does not count as the driver's supply. Mapping which income is which is a job worth doing with an accountant, because getting it wrong in either direction is costly.
How to find out where you stand
Why the label in the contract is not the final word
Operators sometimes describe themselves as "agent" or "principal" in their terms, but for VAT the wording is only a starting point. HMRC and the courts look at substance: who sets the price, who carries the commercial risk, who the passenger believes they are contracting with, and who is responsible if the journey goes wrong. A contract that calls the operator an agent but behaves like a principal supply can be recharacterised. Drivers should therefore treat operator marketing language with caution and rely on the underlying facts and on professional advice, not on a single word in a clause.
This is also why the position can shift over time. If an operator restructures how it accepts bookings, sets fares, or handles passenger complaints, the VAT analysis can move with it. A structure that was agency last year may be reorganised into principal supply, or vice versa, which is one more reason to revisit your own position periodically rather than assume it is fixed.
Why licensing regime drives the divide
The reason London sits apart is structural, not accidental. London private hire runs under a bespoke statute, the Private Hire Vehicles (London) Act 1998, administered centrally by Transport for London, and the courts read that regime as requiring the operator to contract with the passenger. The rest of England and Wales runs under the Local Government (Miscellaneous Provisions) Act 1976, administered by hundreds of separate district and unitary councils, with no equivalent central ruling forcing every operator into the principal role. Two different statutory frameworks produce two different default contracting positions, and VAT simply follows whichever applies.
A Scottish or Northern Irish driver should note that licensing there sits under yet further separate frameworks, so the same fact-led question applies but against a different statutory backdrop. The principle is constant across the UK: identify who supplies the journey, then the VAT treatment follows. The local licensing regime simply shapes the likely answer.
