Can You Fit a Tow Bar to an Electric Car?

Yes, you can fit a tow bar to many electric cars, but not all EVs are approved for towing. Whether yours qualifies depends entirely on what the manufacturer has type-approved for your specific model and variant. Before booking a tow bar fitting, check your car's handbook or the manufacturer's website for the official towing rating. Once you have the right setup, you will also want to plan charging stops differently when towing, since the extra weight and aerodynamic drag will reduce your range noticeably. Use the reg checker to confirm which charging cable your EV uses so you are prepared for stops en route.

Which electric cars can tow?

A growing number of EVs are factory-approved for towing, particularly larger SUVs and family cars. Smaller city EVs are often not type-approved at all, even if a tow bar can be physically attached. The key distinction is type approval: if the manufacturer has not submitted the car for tow testing and approval, you cannot legally tow on public roads with it, regardless of what hardware you bolt on. Always start with the handbook or a call to the manufacturer's customer service line before spending anything on a fitting.

Does towing reduce an EV's range?

Yes, and by more than most drivers expect. Towing adds weight and, more significantly, aerodynamic drag. Both increase energy consumption, which directly cuts into how far your battery will take you between charges. A caravan is particularly punishing because of its large frontal area. The result is that your real-world range when towing can be substantially lower than the WLTP figure you see quoted for normal driving. Plan your journey around shorter legs and more frequent stops, and use your car's navigation or a third-party journey planner that accounts for towing loads.

Do you need to tell the DVLA about a tow bar fitting?

In most cases, no. Fitting a tow bar is a vehicle modification, but it does not usually require you to notify the DVLA or update your V5C. However, the rules can change, and there are specific requirements around trailer registration that do involve the DVLA. Check gov.uk for the latest trailer registration requirements, and always inform your insurer since towing changes your policy terms regardless of what the DVLA requires.

Should you use a detachable or fixed tow bar?

Detachable tow bars are popular on EVs because they can be removed when not in use, which partly reduces the aerodynamic drag penalty of having a fixed bar. They also keep the rear of the car looking cleaner. Fixed tow bars are generally more affordable to buy and fit. Either type is suitable for towing if properly installed by a qualified fitter using a bar that is compatible with your specific car model. Do not assume that a tow bar designed for the petrol version of your car will fit the EV variant: dimensions and chassis points can differ.

How does towing affect charging stops?

Towing changes the logistics of charging stops in two ways. First, you will need to stop more often because range drops with the extra load. Second, many rapid charge points have tight bays that are awkward or impossible to enter with a caravan or trailer attached. Before your trip, use a charging network app or Zap-Map to identify stations with pull-through bays or enough space to disconnect and reconnect the trailer. A portable EV charger is worth keeping in the tow car for emergencies, particularly at campsites with a standard three-pin outlet, but it will charge slowly overnight rather than quickly topping up mid-journey.

What about the electrics: trailer sockets and smart compatibility?

A tow bar on an EV still needs the same 7-pin or 13-pin trailer electrics as any other car. Some EVs integrate trailer detection into their driver assistance systems, which may automatically adjust stability control and other settings when a trailer is connected. Others do not, and you may need to disable certain systems manually. Ask your tow bar fitter specifically about EV compatibility and whether the car's system will recognise the trailer. Getting this right matters for safety, not just convenience.

Frequently asked questions

Can I fit a tow bar to any electric car?

No. Fitting a tow bar only makes sense if your car is type-approved for towing. If the manufacturer has not rated your model for towing, you cannot legally tow on public roads with it, and fitting a bar anyway will likely invalidate your insurance. Check your handbook first.

Will fitting a tow bar affect my EV warranty?

It can, if the tow bar is not installed by an approved fitter or if your car is not rated for towing. Using a manufacturer-approved tow bar and a qualified installer is the safest approach. Some manufacturers offer tow bar accessories through their own dealer network, which protects your warranty cover.

How much will range drop when I tow?

This depends on the weight and shape of what you are towing, your speed, and the weather. Towing a large caravan at motorway speeds will reduce range far more than pulling a small trailer at lower speeds. There is no single figure that applies to all cars and all loads. Always run a trial journey before a long trip to understand your car's real-world consumption when towing.

Do I need to register my trailer?

Trailers above a certain gross weight must be registered with the DVLA and carry a number plate. The thresholds and rules are set out clearly at gov.uk. Check the current requirements before you tow, as the rules have been updated in recent years and the details depend on the type of trailer.

Can I tow a caravan with an electric car?

Yes, if your EV is type-approved for towing and the caravan's weight falls within the car's rated limit. Range will drop considerably, so journey planning is essential. Factor in more frequent charging stops and choose stations with space for a caravan outfit. Some EV drivers find dedicated EV-friendly campsites particularly useful for overnight charging.

Does my insurance cover towing with an electric car?

Not automatically. Towing changes the terms of your motor policy and may require an additional trailer or caravan policy. Contact your insurer before you tow anything, even on a single trip. Failing to declare that you are towing can leave you uninsured in the event of an incident.

Towing with an EV is straightforward once you know your car's limits and plan accordingly. The most important step is confirming type approval before spending anything. After that, the main task is journey planning: shorter legs, more charging stops, and charge points with room for a trailer. Find the right EV charging cable for your car before any long towing trip, and browse the guides for more advice on getting the most from your electric car.
