adm Signal Issue 02: what isn't fixed on your energy bill

adm Signal Issue 02 cover: the charges your fixed price doesn't fix

Welcome to Issue 02 of adm Signal.

Sixty seconds. What's moving on energy and the cost of running a site, without the sales pitch.

1. You fixed your unit rate. These charges aren't fixed.

Your bill isn't only energy. It also carries grid charges, and they rise next April:

  • BSUoS (the cost of balancing the grid minute by minute): the draft rate for April to September 2027 is £21.67 per MWh, 58% up on this year. Final figures in December.
  • TNUoS (the cost of the big transmission lines): forecast to average £30.68 per MWh for businesses, up £5. NESO's 9th October update nudges the fixed daily part up by about another 5%.
  • CCL (the Climate Change Levy, a tax on business energy): 0.827p per kWh from 1st April 2027.

Plenty of "fixed" contracts pass these straight through. Before April, check which lines in yours are fixed and which ones move.

2. Budget on 28th October: don't bank on help with power

Make UK wants levies taken off electricity bills, and 47% of manufacturers say cutting energy costs should be the government's top priority. That's a wish-list, not a promise. So far, the only commitment is to wider business rates reform. Plan your winter as if nothing changes on energy.

One warning light: Cornwall Insight's latest forecast (30th September) has the household price cap rising another 16% in January. Your business contract has no cap at all.

3. Carbon on imported steel and aluminium from 1st January

From 1st January 2027, CBAM (the UK's Carbon Border Adjustment Mechanism) adds a carbon charge to imported iron and steel, aluminium, cement, fertiliser and hydrogen, right down to bolts, screws and aluminium sheet. Import £50,000 or more and you register, report and pay. Ask overseas suppliers for their emissions data now. Without it, you're charged on government default figures.

One question for Monday

Our unit rate is fixed. Which parts of our electricity bill aren't, and who's checking them before 1st April?

If you want a second pair of eyes on your contract's small print, message me. Numbers and options. No hard sell.
