Unit rates vary by region, meter type and payment method. Always compare the full estimated annual cost (unit rates + standing charges) and check exit fees before switching.

Fast answer: which tariffs tend to cut unit rates “this month”?

There isn’t a single public UK list of “tariffs that cut unit rates this month” because suppliers change pricing at different times and offers can be restricted by region, meter type and payment method. In practice, the tariffs most likely to show month-to-month reductions are:

New fixed deals

When wholesale costs fall or competition increases, suppliers often launch new fixed tariffs with lower unit rates than the previous month’s version.

Tracker tariffs

Trackers follow a published formula (often linked to wholesale). Your rate can go down or up frequently, sometimes daily.

EV / time-of-use tariffs

Off-peak unit rates may improve on some plans. Best for households that can shift usage and have a compatible meter (often smart).

Key takeaway: a “unit rate cut” doesn’t automatically mean your bills drop. Standing charges may be higher, discounts may be conditional, and the cheapest option depends on your usage pattern and region.

What to do in 2 minutes

  1. Find your current unit rate and standing charge (bill or app).
  2. Check if you’re on the supplier’s standard variable tariff (SVT) or a fixed deal.
  3. Compare using estimated annual cost (not unit rate alone).

If you only read one thing

To judge whether a tariff that cut unit rates is better for you, compare: (unit rate × your kWh) + (standing charge × 365), then add any exit fees and consider price-change risk (especially trackers).

Compare the latest tariffs (whole of market) for your home

Because “rate cuts this month” depend on where you live and how you pay, the quickest way to find what’s genuinely cheaper is to compare for your postcode and meter type. We’ll show options where the estimated annual cost is lower than your current plan (where possible), and clearly flag key terms like exit fees and fixed end dates.

Good to know: If your current supplier has reduced unit rates on a newer tariff, you may be able to switch internally without a full supplier switch. We’ll still show you broader market options so you can compare fairly.

What you’ll need

  • Postcode (pricing is regional)
  • Whether you have gas + electricity or electricity only
  • Your best estimate of usage (we can still help if you’re unsure)

How to check if a “unit rate cut” is real savings

1) Compare the full price, not just the headline unit rate

A tariff can cut the unit rate but increase the standing charge. Always compare the estimated annual cost using your typical kWh.

2) Check you’re comparing the same region and payment method

UK rates vary by region (electricity distribution area / gas region) and sometimes by payment method (e.g., Direct Debit vs pay on receipt).

3) Confirm your meter setup

Single-rate, Economy 7, smart time-of-use, and prepayment tariffs can price very differently. The “cheapest” deal for one meter can be expensive for another.

4) Look for exit fees and end dates

If you’re in a fixed deal, an exit fee could outweigh a small rate cut. Also check if a low introductory rate later reverts or if the tariff is short-term.

Tariff types most likely to show lower unit rates month to month

Suppliers change prices for different reasons. Understanding the tariff type helps you judge whether the “cut” is meaningful, sustainable, and suitable for your household.

New fixed tariffs (e.g., 12–24 months)

Why rates can drop
Competition and hedging costs change. Suppliers may relaunch a “v2” fixed deal with a lower unit rate than last month’s version.
What to watch
Exit fees, higher standing charges, and whether you’re comparing against SVT or another fixed deal.

Tracker tariffs

Why rates can drop
If the tracked index falls, your unit rate can decrease quickly (but it can also rise quickly).
What to watch
Price volatility, any cap/ceiling in the terms, and how often rates update (daily/weekly/monthly).

Time-of-use / EV tariffs

Why rates can drop
Suppliers adjust off-peak windows and pricing to attract EV/shiftable demand.
What to watch
Higher peak rates. You need the ability to shift usage (and usually a smart meter).

Important: On an SVT (standard variable tariff), your unit rates generally change in line with the Ofgem price cap updates (typically quarterly). Some suppliers may adjust earlier, but SVT pricing is constrained by the cap rules.

Comparison table: what a “rate cut” could mean for your bills

Use this table to sense-check tariff claims. These are illustrative examples using a single-rate meter and typical Direct Debit setup. Your actual quote will depend on your region, meter and supplier availability.

Example tariff change Unit rate change Standing charge change Who it often suits Main risk
New fixed deal launched Down Same or up People wanting predictable costs Exit fees / missing future falls
Tracker rate falls Down (can be quick) Usually stable Risk-tolerant households Rates can rise with little notice
Low unit rate but higher standing charge Down Up Higher-usage homes Low users may pay more overall
Off-peak cut on time-of-use Down off-peak, up peak Varies EV owners / shiftable demand Wrong usage pattern = higher bills

Decision checklist: is a tariff with a rate cut right for you?

Often a good fit if…

  • You can compare using your kWh (or a reasonable estimate).
  • You’re out of contract or exit fees are low.
  • You want price certainty (fixed) or accept fluctuations (tracker).
  • You have (or can get) a smart meter for time-of-use deals.

Think twice if…

  • You’re on a fixed tariff with a meaningful exit fee and only a small predicted benefit.
  • The “cut” is only on unit rate but the standing charge is notably higher.
  • You’re on prepayment and the deal assumes Direct Debit.
  • You have a complex setup (e.g., Economy 7) and the quote doesn’t match your meter.

Two realistic scenarios (with numbers)

Scenario A: a “unit rate cut” that doesn’t help much

Assumptions (illustrative): Electricity only, single rate, Direct Debit. Annual use 1,800 kWh (small flat). Standing charge billed daily.

Item Current tariff New tariff (unit cut)
Unit rate 25p/kWh 23p/kWh
Standing charge 50p/day 65p/day
Annual unit cost (rate × kWh) £450 £414
Annual standing charge (SC × 365) £182.50 £237.25
Estimated annual total £632.50 £651.25

Even with a lower unit rate, the higher standing charge makes the overall estimate higher for a low-usage home.

Scenario B: a rate cut that likely helps a higher-usage home

Assumptions (illustrative): Dual fuel, single-rate electricity, Direct Debit. Annual use: 3,500 kWh electric + 12,000 kWh gas (medium home). Standing charges billed daily.

Item Current tariff New fixed (lower unit)
Electric unit rate 26p/kWh 23.5p/kWh
Gas unit rate 6.8p/kWh 6.2p/kWh
Electric standing charge 55p/day 60p/day
Gas standing charge 30p/day 32p/day
Estimated annual total £1,794.25 £1,651.80

Here, higher usage means the lower unit rates can outweigh slightly higher standing charges. Your quote may differ by region and tariff availability.

Exit fee check: If your current fixed tariff charges (for example) £75 per fuel to leave early, subtract £150 from any first-year benefit before deciding.

Costs, exclusions and common pitfalls (UK)

These are the most common reasons a tariff that looks cheaper on the surface ends up disappointing once you look at the detail.

Standing charges can erase unit-rate cuts

If you use less energy (e.g., small flat, daytime out, efficient home), a higher standing charge can mean you pay more overall even with a lower unit rate.

Payment method differences

Some deals assume Direct Debit. If you pay on receipt of bill or use prepayment, rates and eligibility may differ.

Meter type mismatch (single vs multi-rate)

Economy 7 and time-of-use tariffs need the right meter setup. Switching to a single-rate tariff without considering night usage can increase costs.

Exit fees and contract end dates

Leaving a fixed deal early can carry a fee. Also check if you’re within any fee-free switching window your supplier offers (terms vary).

Trackers: price can rise as well as fall

A tracker that’s cheaper “this month” can become more expensive next week. Make sure you understand how and when it updates.

Limited availability / eligibility

Some tariffs are only open to new customers, certain regions, or require a smart meter. Always check the product terms before switching.

If you’re struggling to pay: don’t switch purely on a “rate cut” headline. You may be eligible for support such as payment plans, emergency credit (prepayment), Priority Services Register help, or grants. See trusted guidance in the sources below.

FAQs

How do I find my current unit rate and standing charge?

Check your latest bill (usually under “Your tariff” or “Price details”), your supplier app, or your online account. Look for pence per kWh and pence per day. For Economy 7, you’ll typically see separate day and night unit rates.

Are unit rates the same across the UK?

No. Electricity prices vary by regional distribution area and gas prices vary by region too. The same tariff name can have different rates depending on your postcode.

Does the Ofgem price cap mean no one can offer cheaper rates?

The price cap limits what suppliers can charge customers on standard variable and certain default tariffs (it’s not a cap on your total bill). Suppliers can offer fixed deals below the capped level, and some tariffs can be higher if they’re not covered (for example, certain specialist products) — always check the terms.

If my supplier cut unit rates on a new tariff, can I switch without changing supplier?

Often, yes — many suppliers allow an internal tariff switch. Whether there’s an exit fee depends on your current contract. It’s still worth comparing the wider market because another supplier’s fixed or tracker could be better for your usage and region.

Can I switch energy if I rent?

In most cases, yes — if you pay the energy bills and your tenancy agreement doesn’t include energy as part of rent. You don’t need the landlord’s permission to change supplier, but you should leave the meter and readings in good order for future tenants.

Will switching affect my smart meter?

Smart meters should continue to work after switching, but functionality can vary depending on meter type and supplier systems. If you’re considering a time-of-use tariff, confirm smart compatibility before you start.

How long does an energy switch take in the UK?

Many switches complete within a few working days, but timings can vary due to meter details, debts on prepayment meters, or data issues. You should not lose supply during a switch.

What’s the biggest mistake people make when chasing lower unit rates?

Comparing only the unit rate and ignoring the standing charge, exit fees, and whether the tariff matches their meter and usage pattern. Always use an annualised comparison where possible.

How we assess “tariffs that cut unit rates this month”

Because there’s no universal monthly register of rate changes, we treat this question as: Which available tariffs today are priced lower than comparable alternatives recently available, and which tariff types are most likely to reduce when market pricing shifts.

  • Comparison basis: estimated annual cost (unit rates + standing charges) using user inputs where provided.
  • UK variables: region, meter type (single/multi-rate/smart), payment method (Direct Debit/prepayment), fuel (electric/gas/dual).
  • What counts as a “cut”: a lower unit rate than the supplier’s previous publicly available version of the same product line, or a lower priced product newly available compared with typical recent market pricing. Availability can change quickly.
  • Limitations: suppliers can withdraw tariffs; some deals are invite-only; headline rates can differ by region; and a lower unit rate may be offset by standing charges or fees.

Sources we rely on

We aim to keep this guide accurate and practical. If you spot something that looks out of date, please compare using your postcode and tariff terms and treat examples as illustrative.

Editorial transparency: EnergyPlus helps households compare tariffs across the market. Quotes are based on the details you provide and tariff availability at the time of search. Prices can change and terms apply.
