Detachable Towbars
More expensive but offering flexibility, detachable systems range from £60-£150 for parts. When combined with installation, expect to pay £500-£1,000. These include vertical and horizontal detachable towballs, allowing you to remove the visible towing element.

Tip from Autodoc Specialists: Always choose type-approved tow bars that meet manufacturer specifications. Non-approved systems may void your warranty and compromise safety systems like parking sensors and reversing sensors.
Costs for the Electrical Kit
Electrical systems are crucial for safe towing, connecting your vehicle's indicators, fog lights, and brakes to the trailer. The choice between 7-pin and 13-pin systems depends on your towing needs.
7 Pin Electric Kit
Standard for basic trailer lighting, costing £50-£100 for parts plus installation. This system handles essential functions like indicators and brake lights. Most vehicle manufacturers require dedicated wiring harnesses rather than universal kits.
13 Pin Electric Kit
Essential for caravans and advanced trailers, with parts costing £80-£150. The 13-pin wiring systems provide additional power for features like reversing cameras and battery charging. Programming the vehicle's on-board computer adds £50-£100 to installation costs.
Modern vehicles often require specific electrical options that integrate with existing safety systems. Non-approved wiring can cause technical issues with parking sensors, Trailer Stability Programmes, and other electronic systems.
| Electric Kit Type | Parts Cost | Installation Cost | Total Cost |
|---|---|---|---|
| 7-Pin Standard | £50-£100 | £100-£200 | £150-£300 |
| 13-Pin Advanced | £80-£150 | £150-£250 | £230-£400 |
