Commercial gas decisions begin with the meter, premises and pattern of use.

Build a defensible shortlist

Obtain written offers close together, confirm the MPRN and start date, and calculate each annual total. Check whether the usage assumption still reflects the site's expected heating or production.

If two offers are close, contract terms, billing support and exposure to variable costs may decide which is suitable.

  • Date and source of each quote
  • Identical consumption and tax basis
  • Unit and standing charges
  • Fees and pass-through elements
