There is a specific kind of taxi firm this post is for: one person, one car, no employees, no ambitions (yet) to run a fleet. Maybe you are taking redundancy. Maybe you are leaving someone else’s firm. Maybe you just fancy being your own boss. Either way, a one-car firm is a real, viable business in 2026, but only if you set it up right.
Going broke in year one usually looks the same. Too much spent on the car, too little on insurance, wrong shifts picked, wrong base picked, and no plan for where bookings actually come from. This post walks through each of those decisions with real numbers.
A heads up: this is not the full licensing guide. For that see our UK private hire licence guide. This is the money and strategy side, which is where most solo operators actually come unstuck.
Lease vs Own: The Honest Comparison
The most common mistake a one-car owner makes is spending too much on the car in month one. You feel like a proper firm if you drive a 2023 Mercedes E-Class. The bank statement says otherwise by month three.
| Option | Upfront | Monthly | Year-one total | Good for |
|---|---|---|---|---|
| Buy used (3 to 5 yo Octavia / Passat / Prius) | £8,000 | £50 servicing reserve | £8,600 | You have the capital, want lowest monthly |
| Taxi-specific PCH lease | £1,000 deposit | £350 to £500 | £5,200 to £7,000 | Cash flow okay, no lump sum |
| Rent-on from existing firm | £0 | £260 to £500 a month | £3,100 to £6,000 | Test the water, lowest commitment |
| New Prius / hybrid taxi finance | £3,000 | £450 to £600 | £8,400 to £10,200 | Fuel savings, long-term plan |
For most first-time solo operators, buying a 3 to 5 year old Toyota Prius or Skoda Octavia outright is the lowest-risk option. You own it. You can stop working without a lease bill. You see the true cost of fuel. And used taxi-ready vehicles hold their value surprisingly well.
The Prius point matters. A diesel Octavia at 45 mpg costs about £110 a week in fuel. A Prius hybrid at 60 mpg costs about £80. £30 a week is £1,560 a year, which covers your entire insurance renewal. Fuel economy is not glamorous, but for a solo driver doing 500 miles a week it is the single biggest lever on take-home pay.
Day Shift vs Night Shift: The Trade-Off
You cannot work 24/7 on your own. You have to pick a shift pattern and stick to it long enough that regulars know when to book you. Two patterns work for solo operators.
- Day: 6am to 4pm, Monday to Saturday. School runs, airport pickups, hospital appointments, account work. Lower fare average (£14 to £18) but more predictable, higher job count, regular patterns. You sleep at night. Life is survivable.
- Night: 6pm to 3am, Tuesday to Saturday. Pub runs, restaurant runs, post-theatre, the odd airport. Higher fare average (£18 to £30), fewer but longer trips, surge on Friday and Saturday. You sleep in the day. Social life is gone.
A mixed shift (“I will do whatever is busy”) sounds flexible and usually produces the lowest take-home. Regular passengers cannot predict when you are available, so they book someone else.
The right answer depends on your town. A commuter town with a big station wants a day-shift firm. A university city with a Friday night culture wants a night-shift firm. A coastal town in summer might support both, but not with one car.
Town vs Airport: Where to Base
The second strategic decision is where you actually sit between fares. Three options for a solo operator.
- Town ranks and high street: Short fares, lots of them, mostly cash and card in-car. Easier to start because word-of-mouth compounds fast in a small town.
- Airport specialist: Longer fares (£40 to £120), pre-booked online or by phone, heavy demand for early morning and late evening. Requires a website that takes bookings properly and a GBP that shows up for “airport taxi from [town]” searches. Less forgiving if you get the website wrong.
- Account work: Solicitors, estate agents, care homes, hotels. Invoice monthly. Very slow to land your first one, utterly reliable once you have three. Can be combined with either of the above.
A typical one-car firm that survives year one is 60 percent town, 25 percent airport, 15 percent account. That mix smooths out the bad weeks and builds a book of customers who are not price-shoppers.
The Break-Even Table
Here is what you actually need to take in a week, depending on your cost base, to break even. Use this as a sanity check before you buy the car.
| Weekly fixed costs | Low setup | Typical setup | New-car setup |
|---|---|---|---|
| Vehicle (lease or servicing reserve) | £30 | £90 | £140 |
| Insurance | £40 | £55 | £70 |
| Plate / compliance | £5 | £5 | £5 |
| Dispatch / software | £8 | £12 | £15 |
| Phone / card machine fees | £10 | £12 | £15 |
| Website / care plan | £7 | £16 | £30 |
| Fixed subtotal | £100 | £190 | £275 |
| Fuel (20% of gross target) | £120 | £160 | £200 |
| Break-even gross (for £0 net) | £220 | £350 | £475 |
| Target gross for £400 net | £620 | £750 | £875 |
A low-setup solo operator needs to be doing about £620 a week gross to take home £400 after fixed costs and fuel. At an average fare of £18, that is 35 fares a week. At 7 fares a day, 5 days a week, that is a realistic target for a working town-shift driver by month three.
A new-car operator needs £875 a week gross for the same £400 take-home. At £18 average, that is 49 fares a week. Same seven days, that is a fare every 90 minutes of driving time with no slack. Doable, but noticeably harder.
Building Word-of-Mouth When You Are the Only Driver
A solo firm lives or dies on repeat customers and referrals. If every fare is a new passenger, you are spending your whole time on marketing and none of it on driving. Four specific things work.
- Always give two cards. At the end of every fare: “One for you, one for a friend.” Costs 2p per fare. Extra cost of ignoring this: the next booking.
- Ask for the review by name. “If I did alright today, would you mind dropping me a Google review? My name is on the card.” Specific beats generic. A direct ask doubles review conversion.
- Text the regular the night before. “Still on for 7am tomorrow, see you at the front door.” It takes 30 seconds. It is the difference between a driver and a firm.
- Make yourself the easiest name to remember. A short firm name. A number people can recall without looking it up. Branding matters less than being memorable. “Dave’s Cars” beats “Premier Executive Transport Solutions” every time.
The Website Question for a One-Car Firm
You do not need a Fleet-tier website on day one. You do need something that is not a Facebook page. The rough rule: if someone hears about you and googles you, what comes up? If the answer is “nothing” or “a page from 2014”, you are losing bookings.
For a one-car firm, a five-page starter site with a fare form, a phone number in the header, and a page per nearby airport is enough. Our Starter tier at £499 one-off is built for exactly this situation. If you cannot spend that yet, a well-set-up Google Business Profile plus a one-page holding site is a reasonable stopgap. See local SEO for taxi firms for the GBP setup.
When to Think About a Second Car
The decision comes up around month nine to twelve. You are turning work away regularly. The phone rings during fares. You have a couple of drivers who have asked if you are hiring.
Three signs you are ready:
- You are turning down at least 5 fares a week that you would have taken.
- Your monthly net has been over £2,000 for three consecutive months.
- You have at least one account client on a regular monthly invoice.
Three signs you are not:
- You have quiet afternoons that would be another driver’s idle time.
- Your GBP ranking is still below the top three in the Map Pack.
- You have not registered for self-assessment yet (see gov.uk set up as self-employed). A second car and a second tax situation is a bad time to discover you have unfinished HMRC paperwork.
If you are not ready, keep the second car money in reserve. A year of emergency cover is worth more than a second vehicle burning idle.
The Three Habits That Separate Surviving Firms From Failing Ones
Across the one-car operations we have seen launch in the last few years, the ones still trading at 18 months have three habits in common. None are remarkable. Together they compound.
- They close the books every Sunday. Not the end of the month, not at tax time. Every Sunday. Fares, fuel, takings, hours. It takes 20 minutes and it tells you what to do on Monday.
- They separate the business bank account from the personal one. Fares in, fuel out, tax reserve to a savings pot. A mixed account is the fastest way to convince yourself you are making money when you are not.
- They treat one passenger a week like royalty. Pick one regular, or one interesting passenger, and do something small: remember their name, carry their bags, text them a happy birthday. That single passenger a week books more fares, and refers more fares, than any ad you could pay for.
Your Move This Week
Do two things this week.
- Work out your own break-even number. Use the table above. Your real weekly fixed costs plus your real fuel, divided by your real average fare, is the number of jobs you need a week to survive. Write it down.
- Decide your shift. Day or night, five or six days. Not “whatever is busy”. A fixed pattern, because regulars can only book a pattern.
When you are licensed and driving, the next thing is the booking channel. Our services page and the portfolio show what that looks like for small firms. The free booking funnel audit applies whether you have one car or fifty.
One car is a real business. Treat it like one and it will pay you. Treat it like a job with a hobby car and it will cost you.
