ScottishPower has returned to Whistl as part of a new contract that will see us process 10 million items of transactional and promotional mail annually.  

Energy Giant Impressed by Whistl's Credentials

ScottishPower serves over five million UK households. Following a competitive tender process, we're delighted to partner with them again and deliver mail management services

The Glasgow-headquartered firm is the first integrated energy company in the UK to generate 100% green electricity. 

As well as the appeal of our service optimisation and hands-on account management, ScottishPower was impressed by our approach to reducing environmental harm. This includes our focus on meeting both our own and our customers' Net-Zero targets.

Through initiatives such as the unique Fuel Carbon Calculator, we enable customers to calculate their reduced carbon emissions through opting to use Hydrotreated Vegetable Oil (HVO) rather than diesel for the collection and trunking of their bulk mail.  

"Sustainability Isn't Just a Goal"

This renewed partnership will put service delivery and sustainability front and centre.

Andrew Ward, CEO of ScottishPower’s Customer Business, said: “At ScottishPower, sustainability isn’t just a goal — it’s embedded in everything we do. We’re proud to partner with Whistl, whose commitment to greener logistics supports our mission to reduce carbon emissions across our operations. This collaboration ensures we continue to deliver for our customers across the UK while staying true to our Net Zero ambitions.”

We are delighted to be working with ScottishPower again. Working in partnership we can help them find efficiencies through optimising their mail operations as well as helping them meet their commitments to reducing their impact on the environment.
