Prices are estimated and change often. Tracker availability varies by supplier, payment method, region and meter type. Always check the supplier’s tariff information label before switching.

Fast answer: the cheapest tracker tariff is the one with the lowest estimated annual cost for your postcode and meter

In the UK, tracker prices can differ by region (distribution area), payment method (Direct Debit vs prepay), meter type (standard vs smart; single-rate vs Economy 7), and how the tariff tracks (e.g., wholesale-indexed vs Price Cap-linked). So there usually isn’t one universal “cheapest tracker” for everyone.

Quick rule: If a tracker’s standing charge is high, it may not be cheapest for low users even if the unit rate looks attractive. Always compare the full estimate.

Key takeaways

  • Trackers can rise quickly (sometimes daily or monthly), so budget headroom matters.
  • Exit fees vary: some trackers are flexible; others charge if you leave early.
  • Eligibility matters: some trackers require a smart meter, online billing, or Direct Debit.
  • Look for caps and protections (e.g., maximum unit rates) where offered—terms vary.

When a tracker is often a good fit

  • You can tolerate month-to-month bill swings.
  • You’re happy to review your tariff regularly and switch if needed.
  • You have some savings/buffer for winter spikes.

When a tracker may not suit you

  • You need predictable monthly payments (tight budget).
  • You’re on prepayment and have limited tariff choice.
  • You’d struggle to respond quickly if prices rise.

Compare tracker tariffs for your home (whole of market)

Tell us the basics and we’ll return options that match your postcode, meter and payment preferences. We’ll show an estimated annual cost so you can compare trackers against fixed deals and your current tariff.

What you’ll need: your postcode and (if possible) whether you have a smart meter / Economy 7.

What “cheapest” means here: lowest estimated yearly cost for your details, not the lowest headline unit rate.

How tracker pricing usually works (plain English)

Unit rate
The price per kWh of energy you use. On trackers, this can change frequently (daily, weekly or monthly depending on the tariff).
Standing charge
A fixed daily charge. Trackers can look cheap on unit rate but still cost more overall if the standing charge is high for your region.
Tracking method
Some track wholesale indices (often more volatile). Others link to the Price Cap or apply a formula. Always read the tariff information label and T&Cs.

Tracker vs fixed vs standard variable (SVT): what to compare

If you’re hunting for the cheapest tracker tariff this month, focus on the features that change the total bill—not just the headline unit rate. The table below shows what normally matters most for UK households.

Feature Tracker tariff Fixed tariff SVT (Price Cap-limited)
Price changes Often daily/weekly/monthly (tariff dependent) Usually fixed for the term (e.g., 12 months) Changes when supplier updates, within Ofgem cap
Best for People comfortable with volatility, watching rates Budget certainty, planning monthly outgoings Default option; less admin, not always cheapest
Standing charge risk Can be high; varies by region and supplier Varies; may be lower/higher than SVT Set by supplier within cap parameters
Exit fees Sometimes none, sometimes yes (check) Common (check amount per fuel) Typically none
Eligibility quirks May require Direct Debit, online account, smart meter (tariff dependent) Direct Debit discounts and credit checks possible Generally available to most customers

Decision checklist (use this before choosing a tracker)

  • What does it track? Wholesale index, cap-based formula, or something else?
  • How often can it change? Daily vs monthly changes affect bill stability.
  • Any caps/floors? Some trackers include limits; many don’t.
  • Exit fees? If rates rise, can you leave without a penalty?
  • Standing charge vs your usage: Low users should be especially careful.
  • Meter & payment requirements: Smart meter / Direct Debit / online-only.

Two realistic scenarios (with numbers)

These examples are illustrative (not a promise). We use simple maths so you can sanity-check quotes.

Scenario A: Low-to-medium user in a flat (single-rate)

  • Assumed usage: 2,000 kWh electricity/year
  • Tracker estimate today: 22p/kWh, 60p/day standing charge
  • Fixed estimate today: 25p/kWh, 55p/day standing charge

Estimated annual cost
Tracker: (2,000 × £0.22) + (365 × £0.60) = £440 + £219 = £659
Fixed: (2,000 × £0.25) + (365 × £0.55) = £500 + £201 = £701

If the tracker unit rate rises by ~3p for much of winter, it may overtake the fixed. Standing charges can vary widely by region.

Scenario B: Typical gas + electricity home (dual fuel, Direct Debit)

  • Assumed usage: 2,900 kWh electricity/year and 12,000 kWh gas/year
  • Tracker estimate today: Elec 23p/kWh + 55p/day; Gas 5.8p/kWh + 32p/day
  • SVT estimate today: Elec 25p/kWh + 55p/day; Gas 6.4p/kWh + 32p/day

Estimated annual cost
Tracker: Elec (2,900×£0.23)+(365×£0.55)=£667+£201=£868; Gas (12,000×£0.058)+(365×£0.32)=£696+£117=£813; Total £1,681
SVT: Elec (2,900×£0.25)+(365×£0.55)=£725+£201=£926; Gas (12,000×£0.064)+(365×£0.32)=£768+£117=£885; Total £1,811

A tracker can be cheaper when wholesale falls, but it can also jump above SVT. Think about your comfort with risk and how quickly you could switch.

Costs, exclusions and common pitfalls (UK-specific)

Trackers can be great value in the right conditions, but “cheap” can disappear quickly. Here are the gotchas that most often explain why a tracker quote looks different from what someone else sees online.

1) Regional pricing (postcode matters)

Standing charges and unit rates vary by electricity and gas distribution region. A tracker that’s “cheapest” in one area may be mid-pack elsewhere.

2) Payment method restrictions

Many competitive trackers assume monthly Direct Debit and online billing. If you pay on receipt of bill or use prepayment, your options may be limited.

3) Smart meter / Economy 7 complications

Some trackers need a smart meter. If you’re Economy 7, you must compare both day and night rates—one cheap rate can hide an expensive other rate.

4) Exit fees and switching speed

If a tracker spikes, you’ll want flexibility. Check for exit fees and remember switching can take time. You can also usually agree a switch date.

5) “Cheap today” isn’t “cheap this winter”

Trackers can move with wholesale markets. If you’d struggle with higher winter bills, a fixed tariff can be a safer budgeting choice even if it’s slightly higher today.

6) Comparing quotes using the wrong usage

If your usage estimate is off, “cheapest” can change. Best practice: use your last 12 months’ kWh (or a recent statement) rather than monthly spend.

Important: The Ofgem Price Cap applies to standard variable and default tariffs, not to most trackers and fixes. Trackers may be priced above the cap at times (depending on the product).

FAQs: cheapest tracker energy tariffs (UK)

Is a tracker tariff always cheaper than a fixed tariff?

No. A tracker can be cheaper when wholesale prices are low, but it can rise quickly. A fixed tariff can be better for budgeting certainty, especially over winter. Always compare the estimated annual cost for your region and meter.

How often do tracker prices change?

It depends on the product. Some trackers update daily (based on a published index or supplier calculation); others update monthly. The tariff documents should state the update frequency and pricing formula.

Can I get a tracker tariff on prepayment?

Sometimes, but choice is usually more limited. Many competitive trackers are for Direct Debit customers. If you’re on prepay, we can still show available options for your postcode and meter type.

Do I need a smart meter for a tracker?

Not always. Some trackers require a smart meter (especially those with more granular pricing), while others don’t. If you’re unsure, check your meter type or use “Not sure” in the quote form.

Will switching to a tracker affect my Warm Home Discount or Priority Services Register?

The Priority Services Register should carry over when you register with your supplier, but you may need to confirm details after switching. Warm Home Discount is scheme-based and eligibility depends on government and supplier rules for the scheme year—check supplier participation and your eligibility before switching.

Are there exit fees on tracker tariffs?

Some trackers are fee-free, others have exit fees (sometimes per fuel). Always check before you switch, because the ability to leave quickly can matter if rates rise.

What’s the difference between a tracker and the Ofgem Price Cap?

The Ofgem Price Cap limits the rates on many default/SVT tariffs. A tracker is a separate product where prices follow a defined formula (often linked to wholesale). A tracker can be below or above SVT depending on market conditions and the tariff’s terms.

What’s the best way to compare tracker deals fairly?

Use the same annual kWh consumption for all quotes, and compare: (1) standing charge, (2) current unit rate, (3) how it tracks and how often it changes, (4) exit fees, and (5) eligibility requirements for your meter and payment method.

How we assess the “cheapest tracker tariff this month”

We’re transparent about what we mean by “cheapest” and what can change. Tracker prices can move frequently, and availability can differ by postcode and customer profile.

Our core definition

“Cheapest” means the lowest estimated annual cost among available tracker tariffs for a user’s postcode, meter type and payment method, calculated using the supplier’s published unit rates and standing charges at the time of comparison.

Assumptions we typically use

  • Usage: Your provided annual kWh, or an estimate if unknown.
  • Payment: As selected (e.g., Direct Debit vs prepay).
  • Fuel: Electricity-only or dual fuel, as entered.
  • Rates: Current published rates; future tracker changes are not forecast.

Limitations (important)

  • Trackers can change quickly, so a quote is time-sensitive.
  • Some tariffs are limited (new customers only, smart meter required, online-only).
  • Exit fees and caps vary and must be checked in the tariff documents.
  • Direct Debit smoothing may not reflect real-time monthly costs.

Trust details

Editorial note: We don’t publish a single named “cheapest tracker tariff” on this page because availability and pricing can vary by postcode and can change at short notice. Instead, we show you how to identify the cheapest tracker for you and provide a quote tool.
