Electrical systems

We supply and fit a comprehensive range of electrical products and systems in both low voltage DC and 110V and 230V mains power.

All mains electrical systems are inspected and independently certified to the latest safety standards


We can supply and fit a range of interior and exterior lights. For most applications we recommend LED sources which are compact, robust, efficient and provide good quality light. A range of styles and fittings are available and we can build and fit custom installations for specialist applications such as product display lighting.

Low Profile Interior Light

Our standard interior light which provides good quality, even lighting in a compact and energy efficient package. Drawing only 0.32A at 12V one of two units will provide plenty of light for most vans.

Interior lights can be slaved to existing door operated timers or attached to a permeant or ignition operated supply and can be switched on the fitting itself or with an additional remote switch


A compact area light suitable for interior or exterior use

  • Aluminium body and heatsink with stainless steel bracket

  • IP67 weatherproof body and connectors

  • Output 3000 lumens, 6000K white

  • 12/24V DC input draws 3.0/1.6A

Warning Lights

We have a large range of beacons and lightbars available including :

  • beacons

  • lightbars

  • dashlights

  • grille lights

  • sirens and reversing alarms

Van Electrical Power Systems

Many basic accessories can be powered from the vehicle's own battery, either on an independent circuit or slaved to the existing interior lights. For more demanding applications we can design and install a variety of high capacity systems including auxiliary batteries, generators and external power hook-ups.


Inverters convert low voltage DC power to high voltage AC and are ideal for low to moderate power consumption including charging batteries and powering electronic equipment.

For most applications we recommend pure sine wave inverters as these are safe for the digital electronics which are now found in many tools and appliances including most battery chargers.

Inverters are rated by peak load and working load. The working load should be greater than the sum of the connected appliances. The peak load provides headroom to accommodate devices with high start-up currents such as electric motors.

Smaller inverters can be run off the vehicle battery but for heavier use we recommend the use of an auxiliary battery system.

Auxiliary Batteries

Auxiliary batteries can provide much more capacity than a vehicle battery alone. Deep cycle lead-acid batteries provide a cost effective and high capacity solution. Unlike standard automotive batteries these can tolerate heavy discharge cycles and as such have much larger useful capacity. Where low weight and bulk are a priority lithium batteries provide the best possible power density.

A simple split charge system allows the vehicles alternator to charge auxiliary batteries by sensing the voltage increase when the vehicle is running and isolates the auxilliary load from the vehicle battery when the engine is not running .

For the most demanding applications we can also supply battery conditioning systems which actively monitor the charge state of the battery bank, balance the load across multiple batteries and provide controlled charging currents to extract the best possible life and performance from the system.

When specifying auxiliary battery systems several factors need to be considered including, average and peak loads, recharging times, initial costs and expected life of the system. In many cases specifying a system with spare capacity can significantly improve its reliability and life expectancy, reducing overall costs in the long term. By considering your likely power requirements and usage patterns we can recommend the most economical and reliable system for your intended application.


Ideal for high power requirements in remote locations, where a lot of power is required over a long period and opportunities for recharging batteries are limited.

Our generator installations include exhaust ducting, ventilation, thermal insulation and guards to allow them to be safely used inside a vehicle. We can also fit partitions and sound insulation to reduce noise levels.

It is very important that generators used in vehicles have an output which can be properly earthed and is compatible with RCD devices, not all generator types are safe for use in vehicles, for this reason we recommend consulting us before specifying a generator for your van.

Note that some equipment such as welding machines and digital electronics may require a generator with voltage regulation.

We can also install safe and secure fuel storage to the latest safety standards.

External link-up

If a nearby source of mains power is available this is usually the simplest and most effective solution, especially for high power consumption applications. The vehicle is fitted with a weatherproof linkup socket which can be plugged into a heavy duty extension lead, powering electrical systems on the van via a consumer unit. An external power socket can also be a useful backup for generator or inverter based systems and allow for secure and convenient overnight battery charging . Multiple linkups can be fitted in parallel for increased capacity . For long cable runs we can supply extra heavy duty link-up cables and extensions.

240V installations are based on a consumer unit with circuit breaker and RCD protection.

External link-ups can also be used to supply a vehicle with power from an external generator or to fast charge high capacity auxiliary battery systems.

All 240V systems are individually inspected and independently certified to the latest electrical safety standards.
