The drain itself, step by step in Swiss Cottage London

Five things to ask a drainer before they set off
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- How much more if the engine has already been started?
- Do you take card payment at the roadside?
- Is there an extra charge at night or at the weekend?
- What is the total, not just the call-out, if it is a straight drain?
- Will you check the filter and pump if the engine ran?
What to do right now
- Don't turn the key.
- Check what went in: the receipt and the pump number tell you the fuel and the litres.
- Call 01295 380724 with those details and your location.
- Get a price that covers the whole job, then book.
- The drainer arrives, drains the tank, flushes the lines and filter if needed.
- You get clean fuel, a running engine and a note of what was removed.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Swiss Cottage London.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
What does it cost in Swiss Cottage London?
The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
How quickly can a drainer reach me in Swiss Cottage London?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
