Can I switch to a monthly energy tracker tariff in the UK?
Yes, if a supplier offers one for your meter and payment type — but monthly trackers can move up or down and may not suit everyone. This guide explains eligibility, how switching works, and how to decide.
- What “monthly tracker” means (and how it differs from daily trackers and fixes)
- Eligibility checks: meter type, region, payment method and credit status
- Two realistic cost scenarios with clear assumptions (so you can sanity-check)
- Common pitfalls: exit fees, standing charges, and price-change timing
Estimates only. Availability, prices and eligibility vary by supplier, region, meter and payment method. Always check tariff terms and your current plan before switching.
Fast answer: usually yes — if a supplier offers a monthly tracker for your setup
A monthly energy tracker tariff is a variable tariff where your unit rates (and sometimes standing charges) are set for a month at a time, then can change next month. You can switch to one if it’s available for your postcode/region, meter type (smart or traditional), and payment method (e.g. Direct Debit).
Key takeaways
- Monthly trackers can fall or rise — they are not price-capped to your current deal.
- You can usually switch away like other domestic tariffs, but check exit fees (some trackers have none, some do).
- Standing charges matter: a tracker with lower unit rates can still cost more if the standing charge is higher.
- Best for engaged households who can tolerate changes and review monthly.
Quick eligibility checklist
- Payment method: many trackers are Direct Debit only.
- Meter: some are available to any credit meter; others may require a smart meter (especially for half-hourly features).
- Region: UK energy pricing varies by distribution region; not all offers exist everywhere.
- Prepayment: monthly trackers are often not available on prepay (depends on supplier).
Important: “Tracker” is not a regulated universal product name. Always read the tariff information label (TIL) and the supplier’s terms to confirm how often prices change, what they’re linked to (if anything), and whether there are exit fees.
How a monthly tracker tariff works (plain English)
With a monthly tracker, your supplier sets your pence-per-kWh rates for electricity and/or gas for a month. Your rates can change at the start of the next month (or on a defined monthly schedule).
What it can be linked to
- Wholesale market movements (not always a strict pass-through)
- A supplier’s internal pricing model
- A published “tracker rate” set each month
What stays the same
- Your meter and supply don’t change
- Your consumption drives your bill most of all
- Ofgem rules on switching and billing still apply
Monthly tracker vs other common UK tariffs
- Fixed tariff
- Unit rates are set for the fixed term (often 12–24 months). You typically pay an exit fee if you leave early.
- Standard Variable Tariff (SVT)
- Supplier’s default variable tariff. Price can change, but SVT rates are limited by the Ofgem price cap (cap level varies by region and payment method).
- Daily tracker
- Rates can change day-to-day. It can be more volatile than a monthly tracker and needs closer attention.
Timing tip: switching doesn’t usually happen instantly. If the tracker price changes monthly, your first month’s rate will be whichever rate applies on your start date (supplier rules vary). Always confirm the start date and rate schedule in writing.
Check tracker availability for your home
We’ll compare whole-of-market home energy deals we can access (including variable and fixed options where available). No obligation.
Before you switch: the 3 checks that prevent most regret
- Exit fee: check your current tariff terms (especially if fixed).
- Payment method: confirm whether the tracker requires Direct Debit.
- Price-change rules: monthly schedule, notice method, and whether standing charges can change too.
Two realistic scenarios (with numbers you can sanity-check)
These examples are illustrative estimates to show how a monthly tracker can compare. Your actual rates depend on region, supplier, meter and payment method. Consumption varies a lot by property and heating type.
Scenario A: medium-use dual fuel household on Direct Debit
- Assumed usage: 2,700 kWh electricity/year and 11,500 kWh gas/year
- Assumed standing charges: 60p/day electricity, 31p/day gas
- Assumed unit rates (tracker month): 24p/kWh electricity, 5.8p/kWh gas
Estimated monthly cost:
- Electricity: (2,700/12 × £0.24) + (30 × £0.60) ˜ £72
- Gas: (11,500/12 × £0.058) + (30 × £0.31) ˜ £65
- Total ˜ £137/month (for that month’s rates)
If next month’s tracker rates rise, your bill could rise without you changing usage.
Scenario B: electricity-only flat (no gas), higher standing charge risk
- Assumed usage: 1,800 kWh electricity/year
- Tracker offer A: 23p/kWh, standing charge 68p/day
- Fixed offer B: 25p/kWh, standing charge 52p/day
Estimated monthly cost:
- Tracker A: (1,800/12 × £0.23) + (30 × £0.68) ˜ £55
- Fixed B: (1,800/12 × £0.25) + (30 × £0.52) ˜ £52
Even with a lower unit rate, a higher standing charge can make the tracker cost more for low-to-medium usage.
Remember: energy is billed in kWh plus daily standing charges, then VAT at 5% for domestic customers. Direct Debit “monthly cost” depends on how your supplier sets payments (it may be a smoothing amount, not the exact month’s usage).
Comparison: monthly tracker vs fixed vs SVT (what usually matters)
| Feature | Monthly tracker | Fixed tariff | SVT (price-capped) |
|---|---|---|---|
| Price changes | Typically monthly (check terms) | Usually no change during term | Can change; limited by Ofgem cap |
| Budget certainty | Medium–low | High | Medium |
| Exit fees | Varies: sometimes none | Common | Usually none |
| Who it tends to suit | Engaged households comfortable with change | Anyone wanting stability | Those who prefer “default” simplicity |
| Key risk | Rates can rise next month | Paying more if market falls | Not always cheapest available |
Decision checklist: a monthly tracker may suit you if…
- You can handle bill swings without missing payments.
- You’re happy to review your tariff monthly (or set reminders).
- You have some flexibility to reduce use (e.g. heating controls, efficient appliances).
- You want to avoid long tie-ins and would value switching again if rates jump.
It may not suit you if…
- You need predictable monthly outgoings (tight budget, fixed income).
- You’re on (or need) prepayment and options are limited.
- You’re in a fixed deal with a large exit fee that outweighs potential benefits.
- You don’t want to monitor prices or can’t act quickly if rates rise.
Practical tip: If you’re curious but cautious, compare (1) monthly tracker, (2) a competitive fixed tariff, and (3) your SVT. The “best” choice depends on your tolerance for change and your standing charges — not just the headline unit rate.
Costs, exclusions and common pitfalls (UK-specific)
1) Exit fees & fixed-term overlap
If you’re currently on a fixed deal, check whether leaving early triggers an exit fee. Some suppliers waive fees in the last few weeks of a fix, but rules vary — confirm in your account or tariff documents.
2) Standing charge shocks
Tracker conversations often focus on unit rates. But if your standing charge is high, low usage homes (many flats) can pay more overall. Always compare unit rate + standing charge together.
3) Payment method exclusions
Many tracker tariffs are built for monthly Direct Debit. If you pay on receipt of bill, use a quarterly budget plan, or need prepayment, your tracker choices may be limited or unavailable.
4) Price-change timing & notice
A “monthly tracker” can mean monthly set rates, but suppliers differ on the cut-off date, when they publish next month’s rates, and how they notify you. Check the terms so you’re not surprised by a change just after you switch.
5) Smart meter misconceptions
A monthly tracker usually doesn’t require half-hourly settlement — but some suppliers’ tracker-style products do. If you don’t have a smart meter, confirm you’re eligible and whether one will be requested.
6) Direct Debit changes
With variable pricing, suppliers may adjust your Direct Debit to reduce the risk of debt (especially ahead of winter). If you want tighter control, consider paying to actual usage where available — or keep a buffer.
If you’re in debt or struggling to pay
Switching supplier can be restricted if you owe your current supplier above certain thresholds or have an active repayment arrangement. Get support first via Citizens Advice energy guidance or speak to your supplier about payment support options.
FAQs
Are monthly tracker tariffs the same as Ofgem’s price cap?
No. The Ofgem price cap applies to default tariffs (like SVT) and sets a maximum level for unit rates and standing charges in each region/payment method. A tracker is a separate product; it may be above or below SVT depending on the supplier and month.
Do I need a smart meter for a monthly tracker?
Not always. Some tracker tariffs work with standard credit meters. However, some suppliers require a smart meter (or will ask to install one) depending on how the tariff is administered and billed.
Can I switch from a fixed tariff to a tracker mid-contract?
You usually can, but you may pay an exit fee. Check your tariff end date, exit fee amount, and whether any fee-free switching window applies. If the fee is high, it can outweigh any short-term benefit.
Can I get a monthly tracker if I’m on prepayment?
Often, tracker-style tariffs are limited or unavailable for prepayment customers, but it depends on the supplier and meter type. If you have (or can get) a smart prepay meter, your options may be different — check eligibility carefully.
How long does switching take in the UK?
Switching is typically completed within a few working days for many customers, but it can take longer if there are issues with meter details, address matching, or debt-related restrictions. Your existing supply continues during the switch.
Will my direct debit change on a tracker?
It can. Suppliers may adjust Direct Debits based on expected annual costs, account balance, and seasonal usage. If prices rise, your monthly payments may increase even if your usage doesn’t.
Can a tracker include electricity-only or gas-only?
Yes — some trackers are available for single-fuel customers, but not always. If you’re electricity-only, standing charge differences can be especially important because you don’t “spread” standing charges across two fuels.
What should I check before agreeing to a monthly tracker?
Check: (1) how often rates change and how you’re notified, (2) whether standing charges can change, (3) exit fees, (4) whether it’s Direct Debit only, and (5) how the supplier sets or reviews Direct Debits.

Our methodology (and limitations)
- Definitions: We treat “monthly tracker” as a tariff where rates are set for a month at a time (supplier terms vary).
- Decision factors: meter eligibility, payment method requirements, standing charges, exit fees, and the user’s tolerance for price movement.
- Scenario maths: Example bills are calculated using annual kWh split into monthly averages, plus 30 days of standing charge. VAT at 5% may apply in real bills (not always shown line-by-line on estimates).
- Limitations: Regional charges vary across Great Britain; tariff availability changes frequently; supplier-specific rules (e.g. notice periods, DD reviews, smart requirements) can differ. Always confirm your personalised quote and tariff documents.
