Where we attend around Bala

We attend right across postcode district LL23 and the roads linking them, including the Bala post town area of Gwynedd. the A487, A470, A55 and A499 are the main routes in, and Snowdonia passes, the Llŷn peninsula and coastal forecourts are familiar ground. Wherever the vehicle stopped, that is where it gets drained. Give your postcode on the phone for a price and an arrival window before a technician leaves.

How serious is it?

Most cars we attend in Bala are fine afterwards, because the driver stopped and called. The ones that are not are the ones that were driven on. Keeping the key out keeps the odds in your favour.

What happens when we arrive

Expect the car to be drained where it stands in Bala, the filter checked as well as the tank, and clean fuel added before a start-and-run check. The contaminated fuel goes with us for licensed disposal.

Common questions

Can I drive with wrong fuel?

No. Starting or driving pumps it through the system and can turn a straightforward drain into an expensive repair. Leave the vehicle where it is and call 01295 380724.

How long does the drain take in Bala?

About 45 to 90 minutes on site once the technician arrives. Vehicles that were started or driven take longer, because the lines and filter need flushing as well as the tank.

How much does it cost in Bala?

Most jobs fall between £199 and £1,999 depending on the vehicle, how much wrong fuel is in the tank and whether the engine was started. You get the price on the phone before we travel.

Will it have damaged the engine?

Only if it has been run through the system. Caught before starting, it sits in the tank and a drain removes it cleanly.

Does insurance cover it?

Often not. Most car insurance policies exclude misfuelling as standard, though some breakdown policies and optional add-ons include it. Check your own wording.

Do you cover rural and island Bala?

Yes. Technicians attend forecourts, roadsides, homes, farms and workplaces across Wales, including the uplands and the islands. Remote jobs are quoted with travel included so the price does not move.
