Different EV charging station environments have their own unique requirements. We operate on retail forecourts, commercial businesses, destination locations and public sector. Click on the links below to learn more about our solutions in each of these areas.

EV Charging installation on forecourts

The forecourt is a logical place for charging points as it is where drivers currently do their refuelling. Existing forecourts are accessible, visible, and already familiar to motorists. Operators are used to hosting infrastructure and providing a service to drivers. By increasing the range and availability of convenience products forecourts can re-focus on non-fuel revenues.

The best chargers for forecourts are ultra-fast, mimicking the dwell time of motorists filling up on traditional forecourts. The below chart shows how many miles of range each type of charger would provide in a typical dwell time of 7 minutes.

Charger type



Slow charger


Up to 2 miles

Fast charger


Up to 4 miles

Existing rapid charger


Up to 23 miles

Ultra-fast charger


Up to 70 miles

Ultra-fast charger


Up to 140 miles

The technical challenge

The APEA Electrical Sub-Group has identified the following risks of installing EV chargepoints on a forecourt, which would need to be carefully considered:

  • The charger and vehicle must be outside the hazardous area
  • The full load of charger(s) must be included in any load calculations
  • If a new supply is required for the EV charger, the supply cable must be routed around the hazardous areas and not run underneath
  • Where the filling station has a TT earthing system it must be used for the EV charger earthing system. Two separate TT earthing systems are acceptable
  • If a separate utility company supply is installed to an EV charger, a warning label must be fitted to indicate that the charger supply is not controlled by the main switch for the filling station
  • The supply to the charger must be interlocked with the filling station electrical controls so that the supply to the charger is switched off when the forecourt is closed (or at least not used if charger is powered for data or similar)

Do you have the space?

The periphery infrastructure (substation, LV panel and power cabinets) takes up a lot of space on a forecourt. A battery integrated charger with an incoming grid connection is an option to provide ultra-fast charging with a small footprint. However, this option isn’t right for a high utilisation forecourt because the battery depletes. This solution would be suitable for up to 20 cars per day max.

Another issue is grid supply with EV providing a challenge to the localised power infrastructure. Many forecourts don’t have adequate power for ultra-rapid charging therefore there would be a cost associated with grid re-enforcement. Thankfully, there is a £950m Government fund to target these costs.

We design, install, and maintain fuel infrastructure for forecourts every day. We understand your risks and hazards and can provide a solution that ensures your forecourt remains safe and compliant. Find out more about our EV chargepoint installation services here.

Commercial business

According to BP it is estimated that by 2030 20% of EV charging will take place at work (up from 5% currently).

As businesses look to decarbonise their operation, a quick win is to install electric car charging stations for employees and clients. Where companies run fleets of vehicles, fast electric car charging stations installed at work locations will reduce running costs.

Your employees, clients and customers want to be able to charge their electric cars while at work or when visiting your business premises. By adding EV charging points you are providing a benefit to your employees and an incentive for clients to do more business with you.

Minimising infrastructure requirements

Most businesses will require multiple electric vehicle charging points. If all these charging points ended up being used simultaneously you could risk overloading the system. Dynamic load balancing smartly allocates available power between the units in use.

If you have 3 units charging at a maximum of 22kW and only 1 EV charging point is being used it will be charged at the full 22kW. However, if all 3 are in use each vehicle would receive 7.3kW of charge.

This keeps the infrastructure requirements to a minimum, ensuring the installation costs remain low. If your electric car parking bays aren’t going to be used at full capacity all the time, this could be an option for you.

Available grants for work EV charging points

OLEV offers government grants for electric car charging points at work via the Workplace Charging Scheme.  It offers a contribution of £350 for each chargepoint installed, up to a maximum of 20, across all sites. Find out more about the Workplace Charging Scheme in our blog here.

Leisure destination

It is estimated that destination EV charging will account for 15% of all charging by 2030 according to BP.

These destinations could be supermarkets, shopping centres, cinemas, hospitality units, anywhere where your customers are parking to access your services. If you offer EV charging for free it is a perk for your customers who are parking and transacting with you anyway. Having EV charging stations at your destination location could become increasingly vital to attracting new business.

A destination charger will need to offer mid-range power with a reasonable level of charge over a dwell time of anything from 1 hour to say 4 hours.

Technical requirements

Most car parks will have lighting at a minimum. If you already have electricity to your site, the process is usually straightforward. If you do not have electricity to your site this is not a deal breaker, it simply means the process is more involved.

On rare occasions the installation work may disrupt your day-to-day operations. An example of this might be in a multi-storey car park where complicated containment work may be required to hide the infrastructure. This may need to be done out-of-hours to avoid disruption to your operation.


Owners can charge users to top up their vehicles, by setting up billing on each EV charging point accessed by a standard RFID charge card. You can determine your own rates which you could choose to do initially to cover the installation costs and then remove this fee once those costs are re-couped, making it a perk for your customers. All data on usage and billing can be managed by a centralised web portal accessible by accounts teams.

Additional Information

Which EV charger is right for you?

We do not have contracts with specific EV charging suppliers meaning we will suggest the right solution for your requirements.

Forecourts tend to install ultra-rapid chargers to emulate the typical dwell time of 7 minutes on a forecourt of traditional petrol and diesel vehicles.

Commercial businesses are more likely to install fast chargers for their fleet vehicles, staff and customers.  Some organisations that specialist vehicles like electric tankers, might consider rapid chargers.

Destination locations will be looking at fast chargers to provide charge to customers while they engage with the services provided, such as shopping. Read more about destination charging in our blog here.

Public sector will be considering various options from fast to rapid chargers. Fast chargers are well suited for public car parks. However, councils may want to offer the option for some drivers to charge and go adding some rapid chargers into the mix. 

Different speeds for different needs

All chargers have different speeds offering varying levels and speed of charge. This table shows the kW and range offered by different charge types to achieve 140 miles of range.

What’s driving the change?

UK EV registrations have increased exponentially since 2019 driven by the banning of diesel and petrol vehicle sales from 2030 in the UK. According to National Grid there will be 36 million EV cars on the roads by 2040.

The increase in the demand for electric vehicles will require a complete shift in the infrastructures of our towns and cities as transport shifts from oil to electricity consumption. 

We will need to install millions of EV charging stations in forecourts, commercial car parks, commercial businesses, and public sector spaces to ensure people have access to charging whenever and wherever is right for them.

A typical installation process

Each project will have a planning phase, procurement phase, along with an installation and commissioning phase:

The planning phase

  • Identify some locations
  • Decide on the number and type of charge point(s)
  • Make initial contact with your DNO to submit an enquiry and discuss network capacity at the locations concerned
  • Appoint an electrical contractor for the charge point installation

Procurement phase

  • Apply for an electrical network connection from your DNO
  • Submit a map where the preferred location is marked with a circle rather than a specific point
  • For multiple applications, prioritise the locations in rank order (most favoured to least favoured) if possible
  • Provide your DNO with the technical data sheet for the charge point types you are planning to install

Installation phase

  • Receive, review and accept the DNO design and quotation received
  • Appoint an electricity supplier who will bill for the electrical energy used
  • Your supplier will appoint a meter operator to install a meter for the charge point

Commissioning phase

  • Agree start and end dates for DNO works
  • Energise your charge point(s)
  • Operation and maintenance
