DNO standing charges: why your electricity bill is higher than your neighbour's

Two households on identical tariffs with identical usage can pay different electricity bills — purely because of where they live. The culprit is the Distribution Network Operator standing charge, which varies across the UK's 14 DNO regions. For heat pump owners comparing tariffs, understanding this regional variation matters: it affects both your daily standing charge and, on some tariffs, your unit rates.

Cosy Octopus vs Octopus Agile: which is better for a heat pump in 2026?

Both tariffs are from Octopus Energy and both can deliver cheap electricity for heat pump owners. But they work completely differently. Cosy gives you the same three cheap windows every day, predictably. Agile gives you 48 half-hourly prices that change daily — sometimes very cheap, sometimes expensive. The gap between the two can be hundreds of pounds a year depending on how much automation you're willing to set up.

EDF FreePhase vs British Gas Heat Power: the no-peak-rate heat pump tariff showdown

EDF FreePhase and British Gas Heat Power are the two main heat pump tariffs without a punishing peak rate. Both give you cheap overnight electricity; Heat Power adds a midday window that FreePhase doesn't have. FreePhase keeps you with EDF and has a simpler three-band day structure. Heat Power gives more total cheap hours but requires switching to British Gas. Here's the head-to-head.

Cosy Octopus vs E.ON Next Pumped: which heat pump tariff wins in 2026?

Cosy Octopus and E.ON Next Pumped are the two most recommended heat pump tariffs in the UK right now. They take opposite approaches: Cosy concentrates deep discounts into 8 hours across three windows but charges a steep peak rate; Next Pumped spreads cheaper rates across 21 hours of the day with no extreme peak. Which one wins depends almost entirely on whether you can avoid those three peak hours.
