Car Hire in the UK: What to Know Before You Book

The UK is an easy country to drive and a poor country to drive in cities, and the gap between those two statements is where most visitors get caught. The motorway network is good and largely toll-free, the countryside is genuinely best seen by car, and the cities are served by rail well enough that a hire car there is a liability with a parking bill attached. There is also a set of charges applying to vehicles entering central London that are collected automatically and reach you afterwards. For the general method, start with how to rent a car abroad without overpaying.

London's charging zones

Central London operates more than one charging scheme, and they are separate things that can apply to the same journey. One charges vehicles for entering a defined central area during defined hours. Another charges vehicles that do not meet an emissions standard for driving within a much larger area. There are no barriers and no booths for either: cameras read the number plate and the charge follows.

The boundaries, the hours, the vehicle criteria and the payment deadlines for these schemes are set by the operating authority and have changed more than once, so check the current rules on the authority's own site rather than relying on a summary — including this one. What does not change is the mechanism, and the mechanism is what costs people money: the charge is not collected at the roadside, it is raised against the vehicle, and it reaches the rental company, which passes it to you with its own administration fee added per notice.

Ask the supplier at the desk how it handles these charges and any penalty arising from them, and get the answer on the agreement. Several other UK cities operate their own clean-air or low-emission schemes with their own rules, so if a city is on your route, check it specifically rather than assuming London is the only one.

The car is for the countryside

The honest structure for most UK trips is rail between the cities and a hire car for the rural stretch. The Highlands, the west coast of Scotland, Snowdonia, the Lake District, Cornwall, the Cotswolds, the Pembrokeshire and Northumberland coasts — all of these need a car and reward one enormously. Central London, Edinburgh, Manchester, Bristol and York do not, and in each the car costs you parking charges and time without returning anything.

Collecting a car at a regional station or airport rather than at a city-centre desk is frequently both cheaper and easier, and it removes the hardest driving of the trip — the first hour, in city traffic, on an unfamiliar side of the road.

Driving on the left, in a manual

• The UK drives on the left, with the steering wheel on the right.
• Manual transmission dominates the fleet, which surprises visitors from countries where automatic is standard. Automatics are available but fewer and dearer, so book one early if you need it.
• Roundabouts are used heavily, including large multi-lane ones. Approach in the correct lane and signal on exit — the convention is consistent and other drivers rely on it.
• Rural lanes in Scotland, Wales, Cornwall and the Lakes are often single-track with marked passing places. Use them to let faster traffic through as well as to pass oncoming vehicles.
• Motorways are largely free to use; a small number of individual crossings and one motorway section are tolled, so check the specific route rather than assuming either way.

The single-track lanes deserve the emphasis. They are the roads that lead to the best parts of the country and the ones visitors find hardest, because the etiquette is unfamiliar and the margins are small. Drive them slowly, expect to reverse to a passing place occasionally, and treat the drystone walls and hedgerows as the fixed objects they are — a scraped panel on a hire car is the most common UK holiday damage there is.

Parking, fuel and the weather

Town-centre parking is generally paid by machine or app with a ticket displayed, and the rules are set locally rather than nationally, so read the sign at the head of the row. Fuel is self-service and stations are plentiful except in the remoter parts of Scotland and Wales, where they can be far apart and keep short hours — a half tank in the Highlands is the point at which to refuel, not a comfortable margin.

Weather changes the driving more than the season does. Rain is possible in any month, and on exposed routes and higher passes it comes with wind and reduced visibility. Build slack into the day rather than a tight schedule.

Before you sign at the desk

• Ask how the supplier handles London and other city charging schemes, and any penalty arising from them, and get it on the agreement.
• Settle your excess cover in advance rather than at the counter — see car rental insurance explained.
• Photograph the car from every angle before driving away and again on return, including wheels, roof, mirrors and windscreen.
• Confirm the fuel policy on the agreement matches the one you booked.
• Whether you need an International Driving Permit alongside your national licence depends on the country that issued your licence — check your own government's guidance rather than the rental company's.
• Ask which charges can arrive after the rental ends — see avoid hidden car rental fees.

Getting the best rate

Airport desks and city-centre desks price differently for the same car on the same dates, and the spread between suppliers at a single location is wider still. Compare car hire in the UK on DiscoverCars, read the reviews for the specific pick-up point rather than the brand, and hold a full-to-full, free-cancellation rate you can re-shop as the dates approach. If you are dropping the car somewhere other than where you collected it, our one-way car hire guide explains how that charge is built.
