How else can you make this trip?
Driving is the focus of this guide; here's how cycling, coach, and (soon) train and plane stack up for the same pair.
What the drive is like
Drafted from the route's computed data on May 16, 2026 and reviewed against the route summary card. Read our methodology.
You leave the honey-colored limestone of Bath by pulling onto the A4, eventually feeding into the M4 at Chippenham for the long haul toward the capital. This route is defined by the transition from the rolling hills of the Cotswolds and the North Wessex Downs into the increasingly dense suburban sprawl of the Thames Valley. Because this is entirely within Great Britain, you stay on the left, but be prepared for the motorway speed limit to drop from 70 mph to 50 mph as you hit the M4's smart motorway sections near Reading and Slough where overhead gantries monitor traffic flow closely.
Traffic intensity shifts noticeably once you cross the M25 orbital. While the motorway surface is generally well-maintained, the final stretch into London often involves heavy congestion. Check your route for the Ultra Low Emission Zone boundaries before arriving; if your vehicle does not meet the standards, you will need to register and pay the daily charge to avoid a hefty penalty. The transition from the high-speed motorway to the stop-start nature of the city grid is sudden, so watch for aggressive lane changes near the airport exits.
Keep an eye on the weather, particularly during the autumn months when damp leaves on the M4 can make the exit slip roads unexpectedly slick. Services are plentiful along the M4 at Leigh Delamere or Reading, providing reliable spots to break the drive before the congestion of London proper begins. Always maintain a sensible following distance in the heavy commuter flow, as erratic braking is common in the final twenty kilometers heading toward the city center.
Route highlights
- The scenic exit from the Cotswold Area of Outstanding Natural Beauty
- Smart motorway gantries indicating variable speed limits near Reading
- The transition into the London ULEZ zone boundaries
- Convenient rest stops at Leigh Delamere motorway services
Trip plan

Must-know before you go
The things a driver from another country wouldn't think to ask about — fines, stickers, payment cards, opening hours.
City access & emission zones
Congestion Charge: £15 inside Zone 1, weekdays 7:00–18:00
Must knowLondon
Stacks ON TOP of the ULEZ £12.50 — so a non-compliant car visiting central London on a Wednesday afternoon owes £27.50. Pay both before midnight the next day. Auto-pay registration is the safest option for a multi-day visit.
Greater London ULEZ — £12.50/day, 24/7
Must knowLondon
The Ultra Low Emission Zone covers every London borough since August 2023. Foreign plates must pay via the TfL website by midnight the day after travel — no payment, £180 fine. A scrappage scheme covers UK residents only. Confirm your car's Euro class on the TfL "check your vehicle" tool before you commit to driving in.
Borders & documents
EU drivers don't need an International Driving Permit
TipA common piece of post-Brexit confusion: EU and UK driving licences are still mutually recognised for short visits. You don't need an IDP for a holiday or business trip. You also no longer need a Green Card — the UK rejoined the unified motor-insurance system in 2021. Bring your registration document and insurance certificate.
What your car must carry
Headlight deflectors required for continental cars
Must knowContinental left-hand-drive headlight beams cut up-and-right — point them straight at oncoming British traffic at night. €15 stick-on deflectors in the right pattern fix this. Many newer cars have a software "tourist mode" in the headlight menu instead. Without one, you'll dazzle every car you pass after dark and risk an MOT-style stop.
Driving rules & habits
Drive on the left — give yourself a buffer day
Must knowSwitching sides isn't the danger people imagine for the first hour — it's the moment you're tired in week 2 and pull into a quiet petrol station. Park, then think. Roundabouts go clockwise; entering one feels backwards. The first 30 minutes after the ferry/Eurotunnel are the highest-risk: take a coffee at a service area before joining the M20.
Fuel stations
Contactless cards work at virtually every motorway pump
TipMajor brand stations (Shell, Total, BP, Repsol, Cepsa, OMV, Eni, Esso) take Visa and Mastercard contactless without an issue. American Express and Diners are spotty south of the Alps. A €100 pre-authorisation hold is normal — it releases within 5 days. Carry €50 cash for the rare independent station.
Money & connectivity
Fuel sold in litres but priced in pence
UsefulPumps quote pence per litre (e.g., 145.9p). Multiply by 100 then divide by 100 to get £/L. Card payments at the pump are universal. Most stations are pay-after-fill — you fuel first, then walk inside. Contactless on a foreign card works almost everywhere; American Express is sometimes refused at smaller stations.
Emergency & breakdown
112 works everywhere in the EU and continental neighbours
TipSingle number for police, ambulance, fire — works from any phone, any network, any country. On motorways, the orange SOS pillars every 2km connect direct to the regional traffic control centre and pinpoint your location. Use them over your phone if you can — it speeds the response.
Rules, fees, and thresholds change. Always verify against the official source the day before you drive — this page is a checklist, not a legal reference.

Overall
Easy
Straightforward drive. One driver, one day, little to worry about beyond fuel and a toilet stop.
- No major complicating factors — motorway-heavy, single country, comfortable length.
Fuel & tolls
Rough cost expectation for a typical EU passenger car. Treat as an estimate — pump prices change weekly.
Petrol (RON 95)
≈ €23
13.6 L × €1.68 / L · 7.5 L/100 km
Diesel
≈ €19
10.9 L × €1.72 / L · 6 L/100 km
Electric (DC fast)
≈ €27
32 kWh × €0.85 / kWh · 17.5 kWh/100 km
Public DC fast charging — slower AC charging at home or hotels typically costs about half.
