You get the price before we set off. - A technician attends with a licensed drainage unit and makes the area safe. - The contaminated fuel is pumped out and the fuel lines are flushed through. - Clean fuel goes in, the vehicle is started and checked, and you drive away. The waste fuel leaves with us for compliant disposal. [Call 01295 380724 now](tel:+441295380724) ## Prices in Caerphilly Call-out is £89 to £199 and the drain itself is £199 to £1,999. The two are quoted separately, and your exact price is confirmed on the phone before a technician sets off. Remote upland and coastal jobs are quoted with travel included, so the figure you are given is the figure you pay. Your situation | What is involved | Typical cost | Time on site | Spotted it, engine never started | Drain the tank, flush the lines, refill with clean fuel | £199 | 45–90 mins | Engine started but not driven | Drain plus a flush of the lines and filter | Mid range | 1–2 hours | Driven a short distance | Drain, flush and a check of the pump and injectors | Higher | 1–3 hours | Driven until it lost power or cut out | Drain, flush and fuel-system diagnosis | Upper end | Assessed on site | AdBlue in the diesel tank | Full drain and flush of tank and fuel lines | Quoted per vehicle | 1–3 hours | [Call 01295 380724](tel:+441295380724) ## Where we attend around Caerphilly postcode district CF83 is covered end to end, along with the roads between, including the Caerphilly post town area of Caerphilly. We reach it on the A470, A467 and A472 and regularly attend the Rhymney valley and the Caerphilly mountain road. Forecourts, roadsides, driveways, car parks, farm tanks and depots are all the same job to us. Tell the operator your postcode and the price and window come before travel. ## How serious is it? Most cars we attend in Caerphilly 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 The visit runs in a fixed order: identify the fuel, isolate the vehicle, pump the tank dry into a sealed drum, flush everything the wrong fuel reached, refill and test. Nothing is left for you to sort out afterwards. ### Districts of Caerphilly we cover [Bedwas](/areas/bedwas-caerphilly/)[Llanbradach](/areas/llanbradach-caerphilly/)[Nelson](/areas/nelson-caerphilly/)[Senghenydd](/areas/senghenydd-caerphilly/)[Ystrad Mynach](/areas/ystrad-mynach-caerphilly/) ### Neighbouring places we cover [Ystrad Mynach Caerphilly](/areas/ystrad-mynach-caerphilly/)[Bedwas Caerphilly](/areas/bedwas-caerphilly/)[Senghenydd Caerphilly](/areas/senghenydd-caerphilly/)[Nelson Caerphilly](/areas/nelson-caerphilly/)[Llanbradach Caerphilly](/areas/llanbradach-caerphilly/)[Rhydyfelin Pontypridd](/areas/rhydyfelin-pontypridd/)[Llanishen Cardiff](/areas/llanishen-cardiff/)[Whitchurch Cardiff](/areas/whitchurch-cardiff/)[Graig Pontypridd](/areas/graig-pontypridd/)[Grangemoor Cardiff](/areas/grangemoor-cardiff/)[Pontypridd](/areas/pontypridd/)[Riverside Cardiff](/areas/riverside-cardiff/)[Danescourt Cardiff](/areas/danescourt-cardiff/)[Trowbridge Cardiff](/areas/trowbridge-cardiff/) ### Elsewhere in Caerphilly [Bargoed](/areas/bargoed/)[Blackwood](/areas/blackwood/)[Risca](/areas/risca/)[Ystrad Mynach Caerphilly](/areas/ystrad-mynach-caerphilly/)[Nelson Caerphilly](/areas/nelson-caerphilly/)[Llanbradach Caerphilly](/areas/llanbradach-caerphilly/)[Bedwas Caerphilly](/areas/bedwas-caerphilly/)[Senghenydd Caerphilly](/areas/senghenydd-caerphilly/) ### Answers [What do I do if I misfuel on the M4?](/answers/what-do-i-do-if-i-misfuel-on-the-m4/)[What do I do if I misfuel on the A55?](/answers/what-do-i-do-if-i-misfuel-on-the-a55/)[Do you cover Anglesey for fuel drain?](/answers/do-you-cover-anglesey-for-fuel-drain/)[What is the phone number for a fuel drain in wales?](/answers/what-is-the-phone-number-for-a-fuel-drain-in-wales/)[How quickly can someone come out for wrong fuel?](/answers/how-quickly-can-someone-come-out-for-wrong-fuel/)[What do I do if I misfuel on the A470?](/answers/what-do-i-do-if-i-misfuel-on-the-a470/)[Is wrong fuel covered by the AA or RAC?](/answers/is-wrong-fuel-covered-by-the-aa-or-rac/)[Who do I call for wrong fuel in Cardiff?](/answers/who-do-i-call-for-wrong-fuel-in-cardiff/) ### Council areas [Isle of Anglesey](/coverage/isle-of-anglesey/)[Gwynedd](/coverage/gwynedd/)[Conwy](/coverage/conwy/)[Denbighshire](/coverage/denbighshire/)[Flintshire](/coverage/flintshire/)[Wrexham](/coverage/wrexham/)[Powys](/coverage/powys/)[Ceredigion](/coverage/ceredigion/)[Pembrokeshire](/coverage/pembrokeshire/)[Carmarthenshire](/coverage/carmarthenshire/)[Swansea](/coverage/swansea/)[Neath Port Talbot](/coverage/neath-port-talbot/)[Bridgend](/coverage/bridgend/)[Vale of Glamorgan](/coverage/vale-of-glamorgan/)[Cardiff](/coverage/cardiff/)[Rhondda Cynon Taf](/coverage/rhondda-cynon-taf/)[Merthyr Tydfil](/coverage/merthyr-tydfil/)[Caerphilly](/coverage/caerphilly/)[Blaenau Gwent](/coverage/blaenau-gwent/)[Torfaen](/coverage/torfaen/)[Monmouthshire](/coverage/monmouthshire/)[Newport](/coverage/newport/) ## What Welsh customers say Rated **4.8 out of 5** from **6,053** verified reviews on [Reviews.co.uk](https://www.reviews.co.uk/company-reviews/store/fuelfixer-co-uk).

Leave the vehicle where it is and call 01295 380724. **How long does the drain take in Caerphilly?** 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 Caerphilly?** 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 Caerphilly?** 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. ### Other sites in this network Fuel Fixer Wales is part of Stockbridge Capital Holdings › Fuel Fixer International › Fuel Fixer Ltd.
