Congestion, ULEZ and clean air zones: what you can claim

Anyone driving for work in a UK city is now paying charges that did not exist a few years ago. They add up faster than people expect, and they are claimable — but only under the same test as everything else.

They are separate from mileage

This is the part worth internalising. The approved mileage rate covers running the vehicle: fuel, servicing, insurance, depreciation. It does not cover what you paid to drive it into a particular postcode.

So congestion charges, ULEZ charges and clean air zone charges on a business journey are claimed in addition to the mileage, not instead of it. The same is true of tolls and crossings.

The test is the journey, not the charge

A charge is claimable if the journey was business travel. It is not claimable if the journey was ordinary commuting — driving into a zone to reach your permanent workplace is your own cost, however unwelcome.

That means the same £15 charge can be claimable on Tuesday and not on Wednesday, depending on where you were going. This is exactly why a per-journey record beats a monthly total: a bank statement showing charges tells you what you paid, not which of them qualify.

Zones vary, and so does what they charge

There is no single national scheme. London's congestion charge and ULEZ are separate things with separate rules. Clean air zones in other cities differ in class — some charge vans and taxis but not private cars, some charge almost everything, some charge nothing for compliant vehicles.

The practical consequence: what you owe depends on the vehicle as much as the city. If you run more than one vehicle, the same trip can cost differently depending on which one you took, and that is worth knowing before you decide which to take.

Keep the evidence attached to the journey

Charges are usually paid online, often days later, sometimes in a batch. By the time it reaches your statement it is a line item with a reference number and no context.

The version that survives a question is the charge attached to the journey it belongs to, with the date, the destination and the reason it was business. Milesheet takes parking, tolls and charges as costs on a trip, with a photo of the receipt or confirmation, and carries them into the monthly statement alongside the mileage — so the claimable ones are itemised where the journey is.
