How Smarter Business can help you compare energy suppliers

The easiest way to save on energy is not by spending time chasing a list of energy suppliers but by going to one place: Smarter Business. For small firms, we can save you time analysing your power and water bills (to see what’s hidden) and take the hassle of trying to contact a list of UK energy suppliers.

Large businesses can benefit from our strategic approach to procurement and our expertise in areas where in-house they may not have a subject covered. Whatever the size of your operation, we can help manage the entire portfolio energy procurement process, secure the right contract and manage the switch.

Did your business pay too much for energy last year? Are you struggling to reduce consumption? We explain how to save your business time and money by asking these questions…

10 questions to ask your business energy provider

About to renew with your energy supplier? Considering contacting the list of energy suppliers on this page? Read this first…

  • Did your business pay too much for energy last year?
  • Are you struggling to reduce consumption?

We explain how to save your business time and money by asking these questions of your supplier, so you can boost your profits and competitiveness this year…

  1. How can you help me reduce my energy consumption? To truly drive down your energy bill you need to stop using so much. Is your supplier giving you the advice and help to do this?
  2. Can you show me my daily energy use? If you can see how much you are using day-by-day or hour-by-hour you can uncover ways to seriously lower your bills. One of the key questions is how much are you using when the business is closed.
  3. How often will you be in touch? You want a supplier that is going to be in regular contact and that you know will be available to answer any questions you have.
  4. How many prices should I get? The problem with going direct to an energy supplier for prices is that you now need to contact multiple suppliers from a list of energy suppliers to get a true spread of prices.
  5. Can you tell me about the laws I have to comply with? Is your supplier informing you about directives and laws that could hit your business in the pocket if you don’t comply? Ask them about the Energy Performance of Buildings Directive, the Energy Savings Opportunity Scheme (ESOS), Display Energy Certificates (DEC), Energy Performance Certificates (EPC) and ISO 50001.
  6. Do you offer energy and water audits? Audits can give your business insight into what you’re using, helping you to reduce consumption by 33% in terms of energy and 45% for water. Can your energy supplier deliver all of these?
  7. Will you help me switch water supplier? In Scotland you can already switch water suppliers – it’s helped businesses there save 20% on their bills. Now many firms can do the same in England. Has your energy supplier told you whether you’re one of them?
  8. Can I have all my bills in the same time period? It’s hard to budget when your utility bills arrive at different times. Can your energy supplier streamline them to suit your needs?
  9. Our deal is restrictive – can you be more flexible? Negotiating the right contract terms and package is a minefield. Are you confident you can secure the right one for your business from your current supplier? Is it offering multiple bespoke deals?
  10. Are my electricity and gas bills correct? Many businesses are paying too much for their energy, sometimes because they don’t understand their bills or they’re on the wrong tariff. Do you have time to check every bill down to the last penny?
