What a classic car actually costs to run: the official figures and the ones nobody publishes

There are two kinds of cost in running a classic. The fixed ones are knowable to the pound, because the government sets or publishes them, and they are almost all lower than for a modern car. The variable ones are where the money goes, and no official source publishes a figure for any of them, because they depend on the car, its condition and its owner.

Here are both, with the official numbers where they exist and honest ranges where they do not.

The fixed costs: mostly zero, all knowable

Vehicle tax. A car in the historic vehicle tax class pays nothing. As of April 2026 the class covers vehicles built before 1 January 1986, the threshold advances each April, and the exemption has to be applied for at a Post Office and then renewed at zero each year. The full rules are in our guide to tax and MOT exemption.

A car too young for the class pays the old engine-size rates if it was registered before March 2001: for 2026/27, £230 a year for engines up to 1,549cc and £375 above that. That is the bracket every modern classic from the late 1980s and 1990s sits in until it ages into exemption, and it is the single largest fixed cost of owning one.

The MOT. The statutory maximum a test station may charge for a car is £54.85, with no VAT on the fee, and the cap has not moved since 2010. A car over forty years old that has not been substantially changed is exempt from the test. The government’s guidance adds that the car must be roadworthy whether exempt or not, and that owners may wish to have it tested voluntarily, which many do after a winter lay-up for the same capped fee.

Insurance Premium Tax is charged at 12 per cent on every motor premium, classic or otherwise. It is the one fixed cost that scales with the variable one.

Clean air zones cost a classic in the historic tax class nothing in the London ULEZ or the English zones, though the London Congestion Charge has no historic exemption and stood at £18 a day from January 2026. The details are in daily driving a classic.

So for a forty-year-old car in regular but modest use, the entire fixed cost of keeping it legal can be the insurance premium and nothing else. That is the arithmetic that makes classics cheap to keep, and it is true.

Fuel: the one cost that is the same as everyone else’s

The government publishes a weekly national average pump price. For the week of 17 August 2026 it put standard unleaded at 161.12 pence a litre, of which 52.95 pence is fuel duty before VAT is applied on top. That is the E10 grade.

Most classics should run on E5 super, for reasons set out in our guide to E10 and classic cars, and here the official record runs out: no government series tracks the super grade, so its premium over E10 is a forecourt observation rather than a statistic, consistently several pence a litre.

Two things soften the fuel bill. An old engine returns fewer miles to the gallon than a modern one, but a classic’s annual mileage is typically a fraction of a daily driver’s, so the total is smaller than the consumption suggests. And the cost is entirely in the owner’s control in a way the variable costs below are not.

Insurance: a quote, not a statistic

The insurance industry’s quarterly tracker publishes a whole-market average for fully-comp private motor cover: £566 in the second quarter of 2026, up one per cent on the quarter and, adjusted for inflation, slightly below a year earlier. It publishes nothing specific to classic policies.

Classic cover is usually well below that average, because it is written on assumptions that reduce the risk: limited annual mileage, secure overnight storage, an older driver, and a second car for daily use. Those conditions are what the low premiums buy, and a policy that breaks them, a daily-driven classic or a young driver, is priced accordingly. The figure for any given car is a quote, and the structure behind it is explained in our guide to agreed value insurance.

Storage: no official figure exists

There is no national statistic for garage rental, lock-up or vehicle storage prices anywhere in the official record. Council garage lettings are local tariffs; commercial storage is a private market. What can be said is that a dry, secure space is the single most effective running-cost control there is, because damp is what produces the one repair that is genuinely expensive, and our guides to winter lay-up and rust both come back to that point.

The variable costs: where the money actually goes

This is the half of the budget no official source covers, because it cannot. The cost of keeping a classic running depends on the car’s condition when you bought it, the marque’s parts support, how much you do yourself, and luck. What follows is the shape of it rather than the figure.

Servicing and consumables. Oil, filters, plugs, points, brake fluid, coolant. On the well-supported engines that power most British classics, covered in our guide to the engines behind British classics, these are cheap and available, and a competent owner does the work on a driveway. The parts bill for a year’s ordinary maintenance on an MGB or a Minor is modest; the labour bill, if a specialist does it, is not.

Tyres. Age fails a classic’s tyres long before tread does, and a set for a car that covers two thousand miles a year is replaced on the calendar, every six to ten years, not on wear.

The parts you did not plan for. Rubber, chrome, glass, trim, and the component that fails without warning on a car where every component is old. Marque support decides whether these are a catalogue order or a search, and it is the largest single variable between one classic and another.

Bodywork. This is the cost that turns ownership into restoration, and it is the one a buyer can control by buying well. A sound shell costs almost nothing to keep sound. A rotten one costs more than the car is worth to put right, for reasons set out in what a restoration really costs.

Specialist labour. Where an owner does nothing themselves, the hourly rate of a classic specialist is the dominant running cost, and it is a figure each specialist sets. The argument for learning the basic jobs, made in our guide to maintenance for beginners, is mostly a financial one.

The budget that works

Experienced owners tend to budget in one of two ways, and both are honest.

The first is a fixed annual sum set aside for the car regardless of what it needs, on the basis that a year with nothing wrong funds the year with something wrong. For a sound, well-supported classic in modest use, a few hundred pounds a year covers consumables and the occasional part; for a car with known needs, a few thousand.

The second is a condition reserve: the cost of the known next job, set aside before the car is bought, because a car with a known structural need is not a cheap car, it is an expensive car with a deposit.

What neither budget should include is an expected rise in value. A classic is not a regulated investment, and advertising that presents any tangible asset as one is subject to the advertising code’s rules on investment claims. The honest position, supported by the auction record, is that most British classics have not kept pace with inflation over the last decade and that the exceptions were not predictable. Buy the car because you want it. A car bought on that basis is cheap to run in every way that matters, because the running is the point.
