Renting a Car in the United Kingdom: 2026 Guide
Renting a car in United Kingdom involves country-specific rules that can surprise US travelers. This guide covers driving laws, fuel costs, insurance gotchas, transmission availability, tolls, and tips that save money and trouble on a UK rental.
Insurance: the most important section
CDW and Theft Protection are usually included in EU rental rates. Excess (deductible) is typically £1,000-£2,000 — buy supplemental "excess waiver" for £8-£15/day to reduce to zero.
Driving in United Kingdom
Side of the road: left. US travelers should practice in low-traffic areas before driving in cities. Roundabouts go clockwise. The driver sits on the right side of the car. Allow 30-60 minutes of orientation before highway driving.
Speed limits: 70 mph motorways, 60 mph dual carriageways, 30 mph urban areas. Speed cameras and radar enforcement are common throughout United Kingdom.
Transmission: Manual transmission default — automatic costs 30-50% more, must be reserved in advance.
Fuel costs and refueling charges
Fuel in United Kingdom costs £1.40-£1.55 per litre (~$6.50-$7.20/gallon equivalent). If you return the rental car below the starting fuel level, the rental company's refueling penalty is typically £2.50-£3.50 per litre (~$11-$15 per gallon equivalent) — about 2-3× the retail pump price.
Same advice as anywhere: self-fill at a gas station 5-10 minutes from the return location, keep the receipt, photograph the fuel gauge before drop-off.
Tolls in United Kingdom
No toll roads in mainland UK. London Congestion Charge (£15/day in central London Mon-Fri) and ULEZ (£12.50/day for older vehicles) apply.

- Reserve automatic transmission 2+ months ahead for summer trips — supply is limited
- Avoid driving in central London — public transport is faster and Congestion Charge adds £15/day
- Scotland and Wales have narrow rural roads — small cars are easier to drive than SUVs
