Supporting the Utilities Industry

Utility Mail Services

Save time and money, increase delivery performance and enhance customer experience with Whistl’s bespoke delivery management, direct mail and postage services.

The UK energy and utilities sector is constantly innovating and transforming. With your company supplying a vital infrastructure of water, gas, electricity or renewable energy to your customers, you have a duty to keep them updated and informed.

We are now a quarter of decade on from privatisation and the UK market has seen significant improvements in productivity, in what is an increasingly competitive environment. One of the key challenges within the utility sector is the best way to achieve the most efficient outcome for your customers, while balancing costs and rewarding your committed workforce.

UK consumers now have more options available to improve their energy efficiencies from the nationwide smart meter roll out giving households more information on energy usage, to improved energy ratings on household appliances and even more energy efficient lighting options. All of these options and products give your customers more ways to take control of their financial outgoings and support the ecosystem. 

Whistl work with a range of energy and utilities companies and understand the importance of communicating effectively with your suppliers, partners and crucially, your customers.


Before making the move to Whistl we were printing, enveloping and posting a large amount of letters internally which took up a lot of time, resources and cost a lot as well. We chose Whistl because their costs are very competitive and their portal is easy.

Unsorted Mail Services

Advertising solutions

If you are trying to acquire customers through direct mail or door to door leaflet advertising, as a utilities company you must ensure a return on investment.

Our door drop services are all targeted at postcode sector level meaning no personal identifying data is used making it a fully GDPR compliant marketing campaign.

With Whistl you have the full access to door drop or mail services including Partially Addressed Mail. With PAM homes targeted postcode level and items are addressed to street and home level but the item does not contain the homeowner’s name. Instead the item is created to appeal to a certain audience profile or has a generic addressed title such as ‘’Energy saver,” which means it is also a GDPR compliant mail marketing channel.


Partially Addressed Mail
