Which UK energy suppliers offer cheap tracker tariffs in May 2026?

Tracker energy tariffs price unit rates against the previous day's wholesale market, plus a fixed margin and pass-through costs. In May 2026 they're consistently cheaper than the April–June Ofgem cap on most days — but they expose households to short price spikes during cold snaps or supply shocks. This page covers which UK suppliers offer trackers, where they sit on price and the questions to ask before moving onto one.

UK tracker energy tariffs and suppliers (May 2026)

A clear, current overview to help you choose with confidence.

What a tracker tariff actually is

Daily unit rate = previous day's wholesale gas/electricity reference + supplier margin + standing charge × 365. The price you pay tomorrow is published today — you can see exactly what you'll pay before you use it.

Where trackers sit in May 2026

Wholesale gas softened through Q1 2026, which is why trackers are running below the cap on most days. April–June 2026 has seen short price excursions on cold mornings, but the monthly average is firmly below cap on typical use.

Who shouldn't pick a tracker

Households on a tight budget who can't tolerate a higher bill in any given month, or who don't have a smart meter and dashboard, should stick with a fixed tariff. Trackers reward people who can shift load and tolerate variability.

Smart meter and dashboard required

All major UK tracker tariffs in 2026 need a SMETS2 smart meter so half-hourly use can be reconciled to daily prices. The supplier app shows the next-day rate before you use it.

    Compare Octopus Tracker, Eon Next Pulse Tracker, EDF tracker and any regional options in your postcode via the form on this page.

  3. 3. Decide risk appetite

    Trackers reward stable or falling markets but expose you to spikes. Make sure you can budget for a bad month.

  4. 4. Apply and submit reads

    Switch completes in 5 working days under Faster Switching.

  5. 5. Set up daily monitoring

    Bookmark the supplier app dashboard so you can see next-day prices.

  6. 6. Shift discretionary load

    Move washing, drying and batch cooking away from peak hours on expensive days to keep the average low.

Common pitfalls to avoid

The most frequent issues we see when households and businesses act on what looks like a good deal.

  • Switching to a tracker without a SMETS2 smart meter — most won't accept you.
  • Picking a tracker when you can't see the next-day price — you're flying blind.
  • Assuming a tracker is always cheaper than the cap — cold-snap spikes can be brutal.
  • Stacking a tracker with high-use winter loads (electric heating, hot tubs) without shifting consumption.

Frequently asked questions

Which UK suppliers offer tracker tariffs in May 2026?

Octopus Tracker, Eon Next Pulse Tracker and EDF's tracker product are the main pure trackers in May 2026. Smaller suppliers like Ebico offer regional trackers. British Gas ‘Halved’ and similar peak-shifting products are time-of-use tariffs rather than pure daily-wholesale trackers.

Is a tracker tariff cheaper than the price cap?

On most days in May 2026, yes — trackers run roughly 5–15% below the April–June 2026 cap. But they move daily, so cold mornings or supply shocks can see the rate spike above the cap for short windows. The monthly average matters more than any single day.

What's the cheapest tracker in 2026?

Octopus Tracker is the most consistently priced low across the year. Eon Next Pulse Tracker is competitive in selected regions. The cheapest on any given day depends on regional pricing — use the form on this page to check live pricing for your postcode.

Do I need a smart meter for a tracker?

Yes — all major UK tracker tariffs in 2026 require a SMETS2 smart meter so half-hourly use can be reconciled to daily prices. Some smaller trackers accept manual reads with daily estimated consumption, but the experience is much worse.

Are there exit fees on trackers?

Octopus Tracker has no exit fees — leave any time with 14 days notice. Most other trackers are similar. Always read the tariff information document before signing.

What's the worst-case on a tracker?

Historical reference: in winter 2022, tracker unit rates briefly hit 80p+/kWh for electricity during European gas supply shocks. The default cap protected cap customers from that. Trackers are a real risk product — only pick one if you can tolerate occasional bad weeks.

Should I move from a fix to a tracker?

Only if you have a SMETS2 smart meter, can monitor daily pricing, and can tolerate short price spikes. If certainty is your priority, a fix is the safer pick. If your usage is shiftable and you check daily prices, a tracker usually wins on annual cost.

Can I stack a tracker with Smart Export Guarantee?

Yes — your import tariff (tracker) is independent of your export tariff (SEG). You can pair Octopus Tracker import with Octopus Outgoing Fixed export to maximise both sides.
