How to cut energy bills by changing direct debit (UK)
Your monthly direct debit can be reduced by switching to a cheaper tariff, correcting your payment amount, and paying based on accurate meter readings. Compare whole-of-market UK deals with EnergyPlus and apply in minutes.
- Find lower monthly payments by switching supplier or tariff
- Fix overpayments by updating your usage and readings
- Compare gas, electricity or dual fuel across the market
- Home energy only (not business), UK-wide
Rates and savings vary by region, meter type and usage. We’ll show available options based on your postcode and current setup.
Reduce your direct debit by switching to a better deal
If your direct debit has jumped, there are usually two levers that bring it down:
- Your tariff (unit rates + standing charge) — switching can lower the cost of every kWh you use.
- Your payment plan — updating estimated usage, readings and credit/debit balance can correct an inflated monthly amount.
EnergyPlus compares whole-of-market home energy options available for your postcode (gas, electricity, or dual fuel). Enter your details and we’ll show routes to a lower monthly payment — including fixes that don’t require switching.
Have a recent bill or app screenshot handy. If you know your annual kWh or have a recent meter reading, your quotes and direct debit estimate will be more accurate.

Direct debit and energy bills: what you’re actually paying for
In the UK, most households pay by monthly direct debit. The supplier estimates your yearly cost (based on usage, unit rates and standing charges), then spreads it across 12 payments. This can help smooth winter spikes, but it also means your payment can be wrong if any of these change:
Your tariff rates
Unit price per kWh and daily standing charge rise or fall. Switching to a cheaper tariff can reduce the bill behind the direct debit.
Estimated usage
If your supplier thinks you use more energy than you do (or you’ve had estimated readings), your monthly payment can be inflated.
Account balance
If you’re in debit after winter, suppliers may increase payments to recover it. If you’re in credit, you may be able to reduce your direct debit.
Simply changing the direct debit amount without fixing the underlying costs can lead to a growing debit balance. The best approach is: get accurate usage ? compare tariffs ? set a realistic monthly amount.
Why your direct debit went up (and how to bring it back down)
If you’ve had a message saying your payment is increasing, it’s usually due to one (or more) of the reasons below. The table shows what to check and what typically fixes it.
| Reason | What you’ll notice | What to do |
|---|---|---|
| Tariff ended (rolled to a higher rate) | Unit rates and/or standing charge increase; bill projections rise | Compare whole-of-market tariffs and switch if there’s a better option |
| Estimated readings | Bills don’t match what you’re using; sudden “catch-up” adjustment | Submit an up-to-date reading (or use smart meter data) before changing payments |
| Winter debit balance | You’re “in debit” and supplier wants to recover it over upcoming months | Switch to a cheaper tariff and set a plan that clears the debit without overpaying |
| Usage changed (WFH, new baby, EV, heat pump) | Higher kWh than last year; supplier’s estimate updates | Use your actual annual kWh and compare tariffs that suit your pattern (e.g. EV-friendly options) |
| Price cap changes and market moves | Standard variable rates shift; projections change | Check whether a fixed rate is cheaper for you right now (and what the exit fees are) |

Step-by-step: cut your direct debit the safe way
Use this checklist to reduce your monthly payment without building up debt on your account.
-
Get an accurate reading (or download your smart meter data)
If your bills are based on estimates, your direct debit can be too high (or too low). A fresh reading gives you a clean baseline. -
Check your account balance
If you’re in credit, you may be able to reduce the monthly amount. If you’re in debit, aim to clear it over a sensible period (often 6–12 months) while also reducing your unit rates. -
Compare whole-of-market tariffs for your postcode
The biggest gains often come from lowering unit rates and standing charge. Switching can reduce what you need to pay each month. -
Choose a tariff that matches your meter and lifestyle
Economy 7, smart meters, EV tariffs and time-of-use plans can change what “good value” looks like. We’ll surface options that fit your details. -
Set a realistic new direct debit
Use your annual kWh × tariff rates, then divide by 12. Leave a buffer for winter if you prefer stable payments. -
Keep it accurate
Submit readings regularly (or ensure your smart meter is communicating) so your direct debit stays aligned with actual usage.
Start with the EnergyPlus comparison form. We’ll help you identify whether switching, correcting usage estimates, or both will reduce your monthly direct debit.
Direct debit savings: practical ways UK households cut monthly payments
1) Switch when your rate isn’t competitive
Even a small change in unit rate affects every kWh you use. Switching to a cheaper tariff can reduce your direct debit without changing your behaviour.
2) Reduce the standing charge impact
Standing charge varies by tariff and region. If your usage is low (small household, flat, efficient home), a lower standing charge can matter a lot.
3) Correct the supplier’s usage estimate
If your annual kWh estimate is too high, your direct debit is often too high. Use your last 12 months’ usage (or latest bills) for the most accurate monthly payment.
4) Avoid “catch-up” shocks with regular readings
Estimated readings can create a big adjustment later. Submitting readings monthly (or ensuring your smart meter connects) keeps payments stable and fair.
If you pay the energy bills, you can usually switch supplier (check your tenancy agreement). If you have a prepayment meter, you can still compare options, and you may be able to move to credit if eligible.
Common mistakes when changing your energy direct debit
It’s tempting to lower your direct debit immediately. These are the most common reasons people end up with bigger bills later.
Lowering it without fixing the tariff
If your rates are high, a lower payment just pushes the cost into a growing debit. Switching to a cheaper tariff tackles the root cause.
Using old usage figures
Household changes matter: working from home, adding an EV, or different occupancy can quickly make last year’s direct debit unrealistic.
Ignoring meter type and tariffs
Economy 7 and time-of-use tariffs can be great (or expensive) depending on when you use electricity. Always compare like-for-like.
Ask what data they used (annual kWh, balance, tariff rates). Then compare alternatives. If there’s a cheaper available tariff, switching can be the simplest way to bring the payment down.
FAQs: changing direct debit to cut energy bills
Can I just change my direct debit amount?
Usually you can request a change, but it’s best to base it on accurate usage and your current tariff. If the payment is too low, you may build up a debit balance and face a larger increase later.
If you want to reduce the amount sustainably, compare tariffs first and update readings/usage. Start here: Compare & reduce.
How do I know if my direct debit is too high?
Check three things: (1) your annual kWh (last 12 months), (2) your tariff rates (unit + standing charge), and (3) your balance (credit/debit). If your projected annual cost is far lower than 12×your direct debit, you may be overpaying.
Submitting a current meter reading often reveals whether your supplier estimate is off.
Will switching supplier change my direct debit date?
Often, yes. Your new supplier will confirm the payment date and amount during setup. You can usually choose from a small range of payment dates. Always keep the old direct debit active until the switch completes to avoid missed payments.
Does changing direct debit affect my credit score?
A normal change to a direct debit amount doesn’t typically affect your credit score. However, missed payments or arrears could. The safest method is to set a realistic direct debit and keep bills accurate with readings.
I have a smart meter — can my direct debit still be wrong?
Yes. Smart meters help, but the direct debit amount can still be set using estimates, balance recovery, or outdated assumptions. Comparing tariffs remains one of the most effective ways to reduce the underlying cost.
