How to dispose of old petrol in Keswick, legally
How do you dispose of old petrol? Not down a drain and not in the bin. Old petrol is controlled waste — small amounts to a council tip, anything more through a registered carrier. Call 01293 248666.

Why you cannot dispose of old petrol down a drain
Old petrol from a mower, a stored car or a forgotten jerry can is classed as controlled waste. Pouring it down a drain or onto the ground is an offence, it contaminates groundwater, and it is a genuine fire risk while you do it.
The options, in order
Small quantities in a proper container can often go to a council household waste site that accepts fuels — check with the local authority for Keswick before you drive there, because not every site takes it. Larger quantities, anything contaminated, or anything still in a vehicle tank needs a registered waste carrier.
What a collection involves
We pump it out, transfer it into a sealed container and leave you with a waste transfer note. That note is the document that discharges your duty of care as the person who produced the waste. Collection is priced per litre plus the call-out.
Around Keswick
Almost every Keswick call is a visitor. There are so few forecourts in the catchment that everyone uses the same handful, usually in the dark after a day on the fells, frequently in a hire car or a campervan they picked up that week. Late afternoon and evening, heavily seasonal, with a pronounced spike in school holidays and bank holiday weekends.
That applies across the villages we cover, including Little Town, Swinside, Seathwaite, Wythburn, Scales, Wythop, Setmurthy, Crosthwaite, Ashness, Manesty, Dockray and Skelgill.
- Stop. Do not turn the key Whatever else happens, this is the decision that matters. Contamination only travels under power.
- Resist the urge to move it The instinct is to get out of the way. Unless you are somewhere dangerous, staying put is the cheaper instinct to follow.
- Safety before diagnosis If you are on a live carriageway, get out and get behind the barrier, and let the police or National Highways deal with the lane first.
- Phone 01293 248666 You will be asked four questions and given a price and an arrival window. Both are honest rather than flattering.
- On-site extraction The tank is emptied, the feed lines are flushed, fresh fuel goes in and the system is primed and run.
- Done, and the waste leaves with us Under a waste transfer note. It is not tipped and it is not sold back to you.
The mechanical reason the advice is always the same
Every drainer tells you not to start the engine, and it is not a sales line. The fuel path runs tank → lift pump → filter → high-pressure pump → injectors, and contamination only moves along it under power. Stationary, the problem stays in the tank where it is cheap to remove. Under power, it spreads into parts that are not.
Borrowdale, Honister and the Whinlatter pass are narrow, steep and busy with walkers. A vehicle stopped on any of them blocks a road with no alternative, and a low-loader often cannot reach where a technician can.

The cost, honestly
Here is how the price actually moves. None of it depends on how many litres of the wrong fuel went in — all of it depends on whether the engine ran.
| Call-out | From just £89 misfuel callout fee |
|---|---|
| Engine never started | Usually the drain and flush only |
| Engine run briefly | Drain, flush, often a new fuel filter |
| Driven some distance | May need the high-pressure pump or injectors checking — a workshop job |
| When you hear the price | On the phone, before anyone travels |
Questions we get asked
Do you cover all of CA12 and the surrounding area?
Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price.
What if I have already driven it?
Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring.
Is this a garage?
No. Wrong Fuel Keswick is mobile. A technician travels to the vehicle wherever it is standing.
What happens to the old fuel?
It leaves with us as controlled waste under a waste transfer note. It is not tipped, and it is not resold to you.
Do I need to stay with the vehicle?
Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it.
Rated 4.8 out of 5
From 2,190 Trustpilot reviews. Reviewers consistently pick out arrival times and the fact that technicians talk them through what happened rather than just taking the keys.
Where reviews are critical, it is almost always about price. Rather than ignore that: the call-out is From just £89 misfuel callout fee, quoted in full on the phone before travel, and we would rather lose the job on the call than argue about it on the forecourt.
