What is a tracker energy tariff and how does it work?

A tracker energy tariff is a variable tariff where your unit rate changes in line with a defined tracker (for example, wholesale market prices or another published index). Your bill is still based on: (1) your unit rates (p/kWh) at the time you use energy and (2) your standing charge (p/day). Because prices can move frequently, tracker tariffs can be cheaper at times but may also rise quickly.

Do I need a smart meter to switch to a tracker tariff?

Not always. Some tracker tariffs work with traditional meters, while others require a smart meter so your supplier can bill accurately when rates change. Before switching, confirm the tariff requirements and whether a smart meter installation is needed.

Will my energy price change every day on a tracker tariff?

It depends on the specific tracker tariff. Some update daily, others update more or less frequently, and some apply a set methodology with published rates. Always check how often rates change, when new prices take effect, and where the supplier publishes the tracker rate.

Is switching to a tracker tariff risky?

Tracker tariffs can be higher risk than fixed tariffs because prices can rise with the market. They may suit you if you can handle price fluctuations, have some budget flexibility, and are prepared to switch again if rates become uncompetitive. If you prefer predictable monthly costs, a fixed tariff may be a better fit.

Can I switch away from a tracker tariff later?

Usually, yes. Many tracker tariffs are variable and don’t have long tie-ins, but terms vary. Check for any exit fees, notice periods, and whether switching triggers any changes to your direct debit or billing schedule.

Are tracker tariffs capped by the Ofgem price cap?

The Ofgem price cap limits the maximum unit rates and standing charges for standard variable tariffs (SVTs) and default tariffs for typical households. Tracker tariffs are often considered a type of variable tariff, but whether the cap applies depends on how the product is structured and regulated. Always check the supplier’s tariff information and terms to understand how pricing is set and any limits that may apply.

How long does it take to switch to a tracker tariff?

A typical energy switch in the UK usually completes within around 5 working days, though timings can vary by supplier and situation (for example, if meter details need updating). Your supply won’t be interrupted during the switch.

What should I check before switching to a tracker tariff?

Before switching, check: (1) how the tracker is calculated and where rates are published, (2) how often prices change, (3) standing charge and any add-ons, (4) exit fees on your current tariff, (5) whether a smart meter is required, and (6) what happens to your direct debit when prices move.

Can I switch to a tracker energy tariff in the UK?

Q: Can I switch to a tracker energy tariff in the UK?

Yes. If your home is supplied by a UK energy provider that offers a tracker tariff, you can usually switch to it like any other tariff. A tracker tariff links your unit rate to a published price (often the wholesale market or a supplier-specific tracker), so your price can go up or down. Check eligibility, any exit fees on your current deal, and whether you have (or need) a smart meter for the tariff you choose.

Yes, in many cases you can. Tracker tariffs follow a published rate (often linked to the wholesale market) so prices can go down as well as up. Compare whole-of-market options with EnergyPlus and see if a tracker could suit your home.

Compare tracker energy tariffs (whole-of-market)

A tracker energy tariff is a variable tariff where your unit rates and/or standing charge track a published benchmark (commonly a wholesale market index). This can mean lower prices when the market falls — but it also means your costs can rise quickly when the market spikes.

If you’re asking “can I switch to a tracker energy tariff in the UK?”, the practical answer is: usually yes, as long as (1) the tariff is available in your region, (2) you pass basic checks (like supply address and meter type), and (3) you’re comfortable with price movements.

Quick reality check before you choose a tracker

Budget certainty: if you need stable monthly bills, a fixed tariff may feel safer.
Risk tolerance: trackers can be competitive, but prices can jump.
Exit fees: some trackers have none, but check your current tariff’s exit charges.

By submitting, you’re asking EnergyPlus to show available tariffs. You can opt out at any time. No obligation to switch.

Tip: If you’re currently on a fixed tariff, check the exit fee and timing before you switch. In some cases, waiting until your fixed term ends can avoid charges.

Tracker tariffs: benefits, risks and who they suit

Tracker energy tariffs aren’t “good” or “bad” — they’re a different way to price your energy. Here’s what to weigh up before you switch.

Potentially cheaper in falling markets

When the underlying tracked rate drops, your tariff can drop too — sometimes faster than standard variable tariffs.

Transparency (you can see the benchmark)

Many trackers publish the reference rate and how your price is calculated (plus any supplier margin), which can make changes easier to understand.

Often flexible (but not always)

Some tracker deals have no exit fees. Others may still have contract terms, so always check the key facts.

Bills can rise quickly

If wholesale prices spike, your unit rates may increase (sometimes daily). Budgeting can be harder.

Not the same as the Ofgem cap

The price cap applies to standard variable and default tariffs — it doesn’t necessarily limit your tracker rate in the same way.

Requires attention

Trackers suit households willing to review tariffs periodically and switch again if market conditions change.

How tracker energy tariffs work in the UK

A tracker tariff typically links your price to an index (for example, a day-ahead wholesale price or another published benchmark). Your final rate is usually:

Your unit rate = benchmark rate (tracked) + supplier margin (and other components) + VAT (domestic)

What changes on a tracker?

Unit rates (p/kWh)

Often move in line with the benchmark. Some trackers update daily; others update less frequently.

Standing charge (p/day)

May be fixed, capped, or variable depending on the product. Always check the tariff information.

How the switching process usually looks

Compare tracker vs fixed vs variable using your postcode and usage (or typical household assumptions).
Check contract terms: length, exit fees, payment method, smart meter requirements (if any).
Apply to switch. In most cases, your new supplier handles the transfer.
Take opening meter readings (unless you have a smart meter sending readings automatically).
Keep an eye on prices and reassess if market conditions change.

Good to know: Your energy supply won’t be interrupted when you switch. You keep the same pipes and wires — only billing and tariff terms change.

Am I eligible to switch to a tracker tariff?

Most UK households can switch, but tracker availability can be more limited than standard fixed deals. Eligibility typically depends on:

Your current contract

Fixed tariff: you may have an exit fee if you leave early.
Variable tariff: usually no exit fee, so switching can be simpler.
Moving home: you can often switch after you’ve taken over supply (and got your first bill/account set up).

Your meter and payment setup

Smart meters: some trackers work best with smart readings, but not all require one.
Prepayment meters: fewer tariffs are available, though options do exist.
Economy 7 / time-of-use: trackers may be limited or structured differently.

Regional considerations (Great Britain & Northern Ireland)

Tariff availability can vary by region and network. Some tracker products are offered only in certain parts of Great Britain, and the market operates differently in Northern Ireland.

Will a tracker tariff save me money?

It depends on wholesale market movements and your usage pattern. Trackers can be competitive when markets fall or remain stable — but they can cost more if prices rise.

Typical costs to check before you switch

Cost item	Why it matters on a tracker	What to do
Exit fee (current tariff)	Leaving a fixed deal early may trigger a fee that wipes out savings.	Check your latest bill or online account and factor it into your decision.
Standing charge	High standing charges can reduce the benefit for low-usage homes.	Compare total annual cost, not just unit rates.
Payment method	Direct Debit tariffs can be priced differently to pay-on-receipt-of-bill.	Select your preferred payment method when you compare.
Price volatility	Your tariff can change frequently, making budgeting harder month to month.	Consider building a buffer into your Direct Debit or savings.

A practical way to decide

Compare annual estimated cost across: (1) tracker, (2) fixed, and (3) standard variable. If tracker is only marginally cheaper, ask yourself whether the extra risk is worth it for your household.

Common mistakes when switching to a tracker tariff

Focusing only on p/kWh

Standing charges, payment method and your real usage can matter just as much. Always compare the total projected annual cost.

Assuming the price cap protects you

The Ofgem price cap is designed around default tariffs. Trackers can behave differently — read the tariff terms carefully.

Ignoring exit fees and end dates

Even if a tracker looks cheaper today, an early exit fee on your current tariff may outweigh the benefit.

Not preparing for volatility

If your bills jump, it can be stressful. Set expectations and keep a buffer where possible.

FAQs: switching to a tracker energy tariff

What is a tracker tariff in plain English?

It’s a tariff where the price you pay is linked to a published benchmark (often related to wholesale energy prices). If the benchmark goes down, your price can go down; if it goes up, your price can go up.

Can I switch to a tracker tariff if I have a smart meter?

Usually yes. A smart meter can help ensure accurate readings and billing, but not every tracker requires one. Availability depends on the supplier and your meter setup.

Are tracker tariffs the same as variable tariffs?

They’re both variable, but a tracker specifically follows a defined benchmark or index. A standard variable tariff can change too, but it’s usually set directly by the supplier and isn’t necessarily tied to a published index.

Will my supply be interrupted if I switch?

No — switching supplier doesn’t change the physical supply. You keep the same gas pipes and electricity network; you’re just changing who bills you and the tariff you’re on.

How quickly can I switch to a tracker tariff?

Timeframes vary by supplier and circumstances. In general, switching can take days to a few weeks. You’ll normally be updated along the way, and your supply stays on throughout.
