Background / who are they

Metro Rod are a national commercial drainage service provider, specialising in all things drain care and repair- from clearing blockages, CCTV drain surveys to innovative pipe laying techniques, they pretty much cover it all. Metro Rod’s distribution model is through franchisees who have rights to specific locations.

Metro Rod HLP (Hull, Lincolnshire and Peterborough) operate from 3 locations and have 27 vehicles in their fleet – a mixture of cars, small and large vans and a couple of HGV’s too – each doing around 100-200 miles per day.

What they needed

Metro Rod HLP reached out to us for help with:

  1. Fleet analysis and suitability assessment for each vehicle
  2. Procuring the right charging infrastructure for their commercial sites and employee homes.

How we helped / what we did

Step 1: Gathered all the information we needed to start the process.

  • Site location and usage data – such as number of parking spaces, operational vehicles, employees and visitors for both their Lincoln and Peterborough offices.
  • Vehicle data – Metro Rod HLP were able to provide telematics data for their entire operational fleet.
  • Employee data – We collected this via telematics where the operational vehicle was home based, or via our Driver Suitability Survey for other employees.

Step 2: Analysed all the data and insights to produce an infrastructure profile and recommendation for the company.

So what did we provide and how did they use it?

  1. Expected energy demand. Based on the telematics data and Driver Suitability Survey results, we were able to estimate the number of company-owned and employee vehicles ready to switch to EV. We then converted the results of this into an energy profile for each of their sites, indicating how much electrical capacity they need.
  2. Required number of business and home charge points. The data we analysed suggested that they’d initially need 4 charge points at the Lincoln site and 1 each at Peterborough and Grimsby which would increase as their fleet gradually switches. This was a pleasant surprise to the company – they thought they’d need more than 4 per site straight away.
  3. Charge point power. Our analysis concluded that 7kW charge points were sufficient for each site – another surprise for the company. They had heard a lot about high-powered charging so thought that drivers would require at least 50kW rapid chargers to keep moving. The telematics analysis and Driver Suitability Survey data indicated that if each company vehicle driver (those likely to hit the 200-mile trip per day) had a home charger and could top-up at work, then a 7kW charger would be more than sufficient. We also determined that there was enough spare electrical capacity at site for the current and future needs.

We covered all the bases for Metro Rod HLP and gave them all the information they needed to make an informed decision and plan for the future.

Step 3: Competitive tender and procurement process

Metro Rod HLP accepted  our recommendations, and we got the ball rolling with the competitive tender process to secure the most effective solution for them. They needed a workplace charging solution that they could monitor via a dashboard, load balance and had no barriers to access for ease of use. Armed with our recommendation and Metro Rod HLP’s requirements, we created a tender and pushed it out to carefully selected suppliers that most closely matched what was needed.

Step 4: Selection and installation

It can be hard to compare electric vehicle infrastructure quotes, so we presented each quote in a standardised and easy to compare format with our recommendation highlighted. Metro Rod HLP then had everything they needed to make a final decision and arrange installation. 


As a result of the work we did they immediately switched 5 of their vehicles to electric, adopted an electric first fleet policy for new vehicles where possible and installed charging infrastructure at 3 commercial sites with selected employee homes in the pipeline.

Shirley Milson, Operations Director, Metro Rod HLP, said:

 “We didn’t know where to start with vehicle electrification, but the team at Diode managed to take the headache away from me and make the process less overwhelming. The team got under the skin of fleet data and employee driving behaviours to help us all understand what our charging infrastructure requirements were. The team is very friendly, professional and was able to respond to all my questions and concerns.”
