A taxi from Grays or anywhere in Thurrock to Heathrow Airport costs £125 fixed with Grays CabLine. That price covers all four terminals, includes live flight tracking, and doesn't change regardless of traffic or time of day.
The Short Answer: £125, All-In
There are no surprises with a Grays CabLine Heathrow booking. The £125 fixed fare applies from Grays town centre, Tilbury, South Ockendon, Chafford Hundred, Orsett, Stanford-le-Hope, and all other points across Thurrock borough. You're quoted £125 before you confirm your booking — and that is exactly what you pay on arrival at the terminal.
There's no meter running. No surge pricing because it's a bank holiday or a Sunday morning. No "traffic supplement." And no booking fee on top.
How Long Does the Journey Take?
From Grays, Heathrow is approximately 28–32 miles depending on your exact pickup address. The route typically runs via the A13, A1089, Dartford Crossing, and M25 westbound to the M4 or M25 J15 / A30 approach.
Off-peak (early morning, late evening, weekends outside peak hours), the journey takes around 45–55 minutes. During peak hours — particularly Friday afternoon M25 traffic, or morning rush hour on the A13 — allow 70–90 minutes.
Our drivers plan departure times around these patterns. For a 6am flight, we'll typically aim to leave Grays around 3:30–4am. For a midday departure, we'll usually suggest leaving by 9am if you want to clear check-in and security comfortably.

What's Included in the £125?
Quite a lot, as it happens. Every Heathrow booking with Grays CabLine includes:
- Door-to-terminal service — we pick you up from your home and drop you at your terminal's departures entrance
- All Heathrow terminals — T2, T3, T4, and T5 at no extra charge
- Live flight tracking on return journeys — if your flight is delayed, your driver's pickup time adjusts automatically
- Meet & Greet on arrivals — your driver waits inside the terminal with a name board
- Free Wi-Fi in the vehicle on request
- DBS-checked, Thurrock Council licensed driver
- No extra charge for early morning or late-night runs
How Does £125 Compare?
Grays to Heathrow via Uber or Bolt will cost you somewhere between £85 and £160+ depending on surge pricing — which is unpredictable at 4am on a Monday. A National Express coach from Lakeside to Heathrow takes around 1 hour 40 minutes and costs around £25–35 per person, but requires you to get to Lakeside first, handle your own luggage, and travel on a shared schedule.
A private taxi at £125 splits extremely reasonably between two passengers at £62.50 each — cheaper than two National Express tickets once you factor in the Lakeside connection. For families or groups of three or four, the per-person cost drops further.
Return Pickups from Heathrow
The same £125 applies on the return leg. For arrivals, your driver tracks your inbound flight and adjusts their pickup time automatically if you're delayed — no need to call. Your driver will be waiting in the arrivals hall with a name board. You can book both legs together by phone, or place two separate bookings online.
