Fast answer: loyalty tariffs can be good, but only if the rates are genuinely competitive

An energy loyalty tariff is a deal your current supplier offers to keep you from switching—often as a fixed tariff or a time-limited discount. Some are excellent; many are simply a new name for a standard deal with higher standing charges, exit fees or conditions that don’t suit your meter/payment method.

When a loyalty deal can be worth it

  • You’re offered lower unit rates and similar/low standing charges versus other tariffs you can access.
  • The exit fee is £0 or you expect to stay for the full term.
  • You prefer minimal admin (no supplier change) and the tariff fits your meter (credit/prepay/smart).

When switching is often better

  • The loyalty offer has high standing charges or a short discount that ends mid-year.
  • You’re on (or moving to) prepayment and the deal doesn’t apply.
  • You want to compare across the market, including different term lengths and features.

The quickest way to judge it

  1. Get the unit rates (p/kWh) and standing charges (p/day) for gas and electricity.
  2. Check term length, exit fees, and whether prices can change.
  3. Compare against other deals using your postcode, meter type and usage.

Important: In the UK, energy prices vary by region and payment method. A loyalty “discount” can still cost more overall if the standing charge is higher or if the discount ends quickly.

How energy loyalty tariff deals work in the UK

Suppliers use “loyalty” offers to keep existing customers. These can appear in your online account, via email, on renewal letters, or through outbound calls. The name varies (for example: “exclusive”, “existing customer”, “renewal”, “retention”, “member”, “priority”).

Common loyalty deal types

Fixed tariff (12–24 months)
Unit rates/standing charges are set for the term (except where contract terms allow specific changes). Often includes an exit fee.
Variable tariff “with discount”
A percentage/£ discount for a period. Rates can change, and the discount can end—your bill may rise afterwards.
Bundled perks
Credits, reward points or added services. Nice extras, but usually less valuable than a genuinely lower unit rate.

Eligibility checks to look for

  • Region: Great Britain tariffs vary by supply region; Northern Ireland has different suppliers and market rules.
  • Meter type: credit meter, smart meter, Economy 7/10, or prepayment.
  • Payment method: monthly Direct Debit, receipt of bill, pay-as-you-go (prepay).
  • Credit checks: some fixed tariffs require a credit check (especially for monthly Direct Debit).
  • Fuel type: dual fuel offers may not apply if you only have electricity.

What to ask your supplier (copy/paste)

  • What are the electricity unit rate (p/kWh) and standing charge (p/day) for my postcode?
  • Same question for gas (if applicable).
  • Is it fixed or variable? If fixed, when does it end?
  • Are there exit fees and do they apply per fuel?
  • Does it require monthly Direct Debit or a smart meter?

Good to know: If you’re on a fixed deal, UK rules allow you to switch without exit fees in the final 49 days of the contract. Always confirm your end date with your supplier.

Two realistic scenarios (with numbers)

These examples show how to compare costs. They are estimates using typical consumption levels. Your actual costs will vary by region, tariff rates, and standing charges.

Scenario A: Dual fuel, monthly Direct Debit

Assumptions: Medium user in Great Britain (illustrative): 2,700 kWh electricity + 11,500 kWh gas per year. Standing charges shown per day.

Loyalty fixed offer (12 months): Elec 26p/kWh + 60p/day; Gas 6.5p/kWh + 34p/day; exit fee £50 per fuel.

Alternative switch deal (12 months): Elec 25p/kWh + 52p/day; Gas 6.4p/kWh + 30p/day; exit fee £0.

Estimated annual cost difference: Loyalty ≈ £1,561 vs Switch ≈ £1,472 → Switch ~£89/year cheaper (before any cashback/perks). If you might leave early, add potential exit fees to the loyalty deal.

Scenario B: Electricity-only flat, low usage

Assumptions: Low user: 1,800 kWh electricity per year. Standing charge matters more when usage is low.

Loyalty variable with discount: 26p/kWh + 67p/day, “10% off unit rate for 6 months”, then reverts (discount value depends on future rates).

Alternative fixed: 25.5p/kWh + 52p/day, no discount, £0 exit fee.

Estimated annual standing charge difference: (67p−52p)×365 ≈ £54.75/year extra on the loyalty tariff before unit-rate differences. For low users, a higher standing charge can wipe out a headline “discount”.

To run your own comparison: multiply unit rate by annual kWh, add standing charge × 365, then adjust for any credits/exit fees. If you’re unsure of your usage, use an estimate (we explain our approach below) and refine it once you have a bill.

Compare loyalty deals against the market (no guesswork)

If you’ve been offered a loyalty tariff, the simplest check is to compare it with other tariffs available for your postcode and meter type. Fill in the form and we’ll use your details to help you compare options across the market.

By submitting, you confirm this is for a UK home energy comparison. We’ll use your details to provide quotes and contact you about your comparison. You can opt out at any time.

What to have to hand (optional)

  • Your loyalty offer’s unit rates and standing charges (gas + electricity)
  • Any exit fee and the end date of your current contract
  • Recent annual usage (kWh) from a bill, or your best estimate

Tip: If the loyalty deal is described mainly in £/month, ask for the p/kWh and p/day figures. Those are what you need to compare fairly across suppliers.

How switching usually works (UK)

  1. Choose a tariff that matches your meter and payment preferences.
  2. Your new supplier arranges the switch; your supply stays on throughout.
  3. Take meter readings when asked and keep an eye out for the final bill.

Timescales and steps can vary, especially for prepayment and some meter types.

Loyalty tariff vs switching: a quick comparison (what to check)

Use this table to spot the differences that most often change the outcome—especially standing charges, exit fees, and who can access the deal.

What you’re comparing Loyalty/renewal deal Switching deal (new supplier) Why it matters
Unit rates (p/kWh) Often competitive, but not always Varies widely across the market Main driver of cost for medium/high usage homes.
Standing charges (p/day) Can be higher on “discounted” deals Some deals keep these lower Crucial for low usage and electricity-only properties.
Price certainty Can be fixed or variable Can be fixed or variable Fixed helps budgeting; variable can change with supplier pricing.
Exit fees Common on fixed renewals Often £0, but not always If you might move home or want flexibility, fees matter.
Eligibility May require Direct Debit, smart meter, credit check Different suppliers have different criteria The “best” tariff isn’t useful if you can’t access it.
Support & admin No supplier change; just a new tariff New supplier onboarding; handover process Convenience may matter if you’re mid-move or time-poor.

Decision checklist: who loyalty deals often suit

  • You’re happy with your supplier’s service and want a simple renewal.
  • You’ve checked the standing charge isn’t inflated versus alternatives.
  • You want budget certainty and the fix length matches your plans.
  • You’re near the end of a fix and can move tariff without penalties.

Who loyalty deals often don’t suit

  • Low usage homes where a high standing charge is a big share of costs.
  • Anyone who may move home or wants to keep switching options open.
  • Prepayment customers offered deals that only apply to Direct Debit.
  • Homes with Economy 7/10 or complex meters where a “standard” quote is misleading.

Quick rule of thumb: Don’t decide based on £/month alone. Compare p/kWh + p/day, then factor in exit fees and the date any discount ends.

Costs, exclusions and common pitfalls (UK)

Loyalty tariffs aren’t “bad”—but the details determine whether they’re good value for your household. Here are the issues we see most often.

1) Higher standing charges

A loyalty deal can advertise a decent unit rate while quietly raising the standing charge. This hits low usage properties hardest.

2) Exit fees (often per fuel)

If you take a dual fuel fix, you might pay an exit fee for gas and electricity separately. Check your flexibility if you might move or refinance budgeting.

3) Short discounts that end suddenly

A “6-month discount” can revert to a higher variable rate. Put the discount end date in your calendar and check what the tariff becomes afterwards.

4) Meter/payment exclusions

Some loyalty deals exclude prepayment, Economy 7/10, or customers not paying by monthly Direct Debit. Always check your exact meter and payment method.

5) “Estimated monthly cost” based on wrong usage

If the supplier assumes higher (or lower) kWh than you actually use, £/month comparisons can mislead. If possible, use your annual kWh from a bill.

6) Timing your renewal

Renewing too early might lock you into exit fees if a better deal appears later. Near the end of a fix, you usually have more freedom to move.

Watch out for sales pressure: If someone calls claiming a loyalty deal is “ending today”, ask them to email the full tariff details so you can compare unit rates, standing charges and fees. Genuine offers should be confirmable in writing.

FAQs

Are loyalty tariffs cheaper than switching in the UK?

Sometimes, but not automatically. The only fair check is comparing unit rates (p/kWh) and standing charges (p/day) for your region, then factoring in exit fees and any time-limited discounts.

What information do I need to compare a loyalty offer?

Ask for (1) electricity unit rate + standing charge, (2) gas unit rate + standing charge (if applicable), (3) whether it’s fixed/variable and the end date, (4) any exit fees, and (5) eligibility rules (Direct Debit, smart meter, prepay, credit check).

Can I get a loyalty deal if I’m on a prepayment meter?

It depends on the supplier. Some offers are limited to monthly Direct Debit customers. If you’re on prepay, check that the tariff is available for your exact meter type and how top-ups/charges work.

Will switching affect my gas/electric supply?

No—your energy supply stays on. What changes is which company bills you. You may be asked for meter readings near the switch date, and you’ll receive a final bill from your old supplier.

Do loyalty deals include exit fees?

Many fixed loyalty/renewal tariffs do, and fees can apply per fuel. If flexibility matters, prioritise £0 exit fee tariffs or check when fees no longer apply near your contract end.

Is a “discount” loyalty tariff always a good sign?

Not necessarily. A discount can be offset by a higher standing charge, or it might apply only for a short period. Always look at the full tariff details and what happens when the discount ends.

Do prices differ by where I live in Great Britain?

Yes. Unit rates and standing charges vary by supply region (and can vary by payment method and meter type too). That’s why postcode is essential for accurate comparisons.

I don’t know my annual kWh—can I still compare?

Yes. You can use a reasonable estimate at first (for example based on household size/property type) and then refine it when you have a bill. Standing charges still matter even without perfect usage figures.

If you’re being asked to renew: take 5 minutes to compare. Even if you stay with the same supplier, you’ll feel more confident you’re on a fair deal.

How we assess loyalty tariffs (our approach)

  • We compare the right numbers: unit rates (p/kWh) and standing charges (p/day) for gas and electricity, not just £/month.
  • We check eligibility constraints: region, meter type (including Economy 7 and prepayment), payment method, and whether a credit check is likely.
  • We account for friction costs: exit fees, discount end dates, and whether the tariff is fixed vs variable.
  • We focus on household outcomes: low, medium and higher usage patterns can flip which deal is best, especially because standing charges are paid regardless of consumption.

Limitations: Examples on this page use illustrative rates and typical annual consumption levels to show the maths. Your actual comparison depends on live tariffs for your postcode and your usage—especially if you have a smart tariff, multi-rate meter, or atypical consumption.
