About the Service
What is Mobile Jump Start Service?
A car that won't turn over in a supermarket car park at 10pm doesn't need a taxi home — it needs a jump start from someone with the right kit. Domestic booster cables from a supermarket rarely have the amperage to crank a modern diesel or a start-stop petrol; and clipping cables to the wrong terminal on a modern car can fry the ECU.
Who needs it?
Our mobile jump start service uses professional-grade lithium jump packs rated for petrol, diesel and modern start-stop vehicles. We connect at the manufacturer's designated jump points (never the battery on modern engines), verify charging voltage, and run a full diagnosis to tell you whether the battery will survive or whether you need a replacement.
When should you call?
The moment you notice a problem. Our dispatch line is live-answered 24 hours a day, 365 days a year — there's no automated menu, no queue, and no premium for evenings, weekends or bank holidays. Call +44 7949 891689 or WhatsApp, describe what you're seeing, and we'll confirm a total price and dispatch time before a van moves.
Warning Signs
Signs you need this service.
If any of these apply, we can be with you in 30–60 minutes.
Engine cranks slowly
Sluggish, laboured cranking on a cold morning — the classic first sign a battery is failing.
Clicking, no start
Rapid clicking from the starter solenoid means voltage is too low to engage the motor.
Dashboard warning lights
Battery, ABS, ESP or ECU warnings that flicker on and off point to poor voltage regulation.
Battery age over 4 years
Most start-stop AGM/EFB batteries need replacing every 4–5 years, even without symptoms.
Repeated jump-starts
If you've jump-started more than twice in a month, the battery is finished — not the charging system.
Left lights on overnight
Deep discharges permanently damage lead-acid cells; a jump gets you home but replacement follows.
Benefits
Why customers choose this service over a garage.
Professional jump packs
Lithium jump starters rated to 3,000A peak — cranks any petrol or diesel including large SUVs.
Correct connection points
We use the OEM-designated jump points on modern engines — no clipping to the battery of a car that shouldn't be jumped that way.
Diagnosis included
Every jump start includes a battery and alternator check so you know whether it'll happen again.
Battery replacement on-scene
If diagnosis shows the battery is done, we can replace on the same visit with a coded OEM-grade battery.
24/7 · no surcharge
3am, Christmas Day, bank holiday — same price, same service level.
Fully insured
£10m public liability. Every visit photographed and receipted.

Mobile Car Battery Replacement in London
Modern car batteries are more than a lead-acid box. Start-stop systems need AGM or EFB chemistry, and every replacement on a modern German, Japanese or Korean car requires the Battery Management System (BMS) to be coded to the new battery — otherwise the charging profile will over-charge and destroy the new battery within months.

Roadside Rescue · 24/7
Roadside Tyre Assistance in London
When you're stopped on a hard shoulder, a lay-by or the pavement at the end of a residential street, roadside tyre assistance is not the same as booking a fitting slot. It's an emergency service that has to arrive fast, work safely in live traffic, and have the correct tyre on the van when it gets there. That is what we specialise in.

Q · 01How quickly can you arrive to jump-start my car?+
Q · 01
How quickly can you arrive to jump-start my car?
Median arrival across London is 28 minutes. Outer boroughs and Essex are typically 35–50 minutes depending on time of day and traffic.
Q · 02Can you jump-start a start-stop car safely?+
Q · 02
Can you jump-start a start-stop car safely?
Yes — start-stop cars need connection at the designated jump points, not directly on the battery. Our jump packs are rated for the higher inrush current those systems demand.
Q · 03How much does a mobile jump start cost?+
Q · 03
How much does a mobile jump start cost?
Quoted upfront on the call — the same price at 3am as at 3pm. No weekend, night or bank-holiday surcharges. Call +44 7949 891689.
Q · 04What if my battery is dead and won't hold a charge?+
Q · 04
What if my battery is dead and won't hold a charge?
We diagnose during the visit. If the battery is finished, we can supply and fit a coded OEM replacement on the same call — no second callout needed.
Q · 05Do you jump-start diesels?+
Q · 05
Do you jump-start diesels?
Yes — our lithium packs are rated to 3,000A peak, enough to crank up to 8.0L diesels including motorhome fitments.
Q · 06Can you jump-start an EV or hybrid?+
Q · 06
Can you jump-start an EV or hybrid?
The 12V accessory battery in hybrids and EVs can be jump-started safely — we do this regularly for Tesla, Prius, Ioniq and Kona EVs.
Q · 07Will jump-starting my car damage the electronics?+
Q · 07
Will jump-starting my car damage the electronics?
Not when done correctly at OEM-designated points with a regulated jump pack. Damage risk comes from ordinary cables from another car — which is what our pack replaces.
Q · 08Do you attend supermarket and multi-storey car parks?+
Q · 08
Do you attend supermarket and multi-storey car parks?
Yes — as long as we can get the van within 5–10 metres of your vehicle.
