Cheapest Energy Tariff by Postcode UK (July 2026)
There is no single “cheapest” UK energy tariff — Ofgem caps differ by region, distribution network operators charge different daily fees, and several suppliers only operate in part of the country. The deal that wins in EX1 (East Devon) is rarely the one that wins in LL57 (North Wales). This page explains exactly why your postcode changes the price, shows the cheapest live fixes in July 2026, and lets you run a whole-of-market quote in 60 seconds now the 1 July 2026 cap has risen to £1,862.

Quick answer: what is the cheapest energy tariff by postcode?
There is no single national winner. In July 2026 the lowest UK-wide 12-month fix is E.ON Next Fixed at ~£1,602/yr typical dual-fuel, then Octopus 12M Fixed (~£1,632/yr) and EDF Essentials Plus (~£1,649/yr) — all roughly £200–£260/yr below the £1,862 cap that takes effect on 1 July 2026. Your exact cheapest tariff depends on your postcode, because Ofgem sets 14 regional caps, your DNO sets the daily standing charge (electricity ranges ~58p/day in the East Midlands to ~70p/day in Merseyside & North Wales), and some suppliers don’t serve every area. Enter your postcode in the form below to see the live cheapest deal for your DNO region in about 60 seconds.

Compare by postcode — not by national average
The national “£1,862 cap” headline hides a regional spread of around £150/yr on the same usage profile. The cheapest electricity standing charge in July 2026 is the East Midlands at ~58p/day; the highest is Merseyside & North Wales at ~70p/day. Gas standing charges range from ~28p/day in the South West to ~37p/day in Northern Scotland. A postcode quote is the only way to see your real number.
On top of the regional caps, individual suppliers price differently — Octopus, EDF and E.ON adjust unit rates by DNO region, while Utility Warehouse and Rebel Energy don’t serve every postcode at all. We check all of these in a single lookup, so you don’t have to load each supplier’s site separately.
With the cap rising on 1 July, the value of comparing now is simple: a fix taken today locks in a rate roughly 13% below the new cap and shields you from the increase for 12 months. Standard variable customers who do nothing pay the higher cap from their first July meter reading.

Why your postcode changes the price
Three factors make tariffs postcode-dependent in July 2026:
1. Ofgem regional cap
Ofgem sets 14 different price caps — one per electricity distribution region. The headline £1,862 is a national average; your real cap is set by your DNO area.
2. DNO standing charge
Your network operator charges the supplier a daily fee to maintain the local grid, which is passed through to you. Rural regions and the islands pay more because of network upgrade costs.
3. Supplier footprint
Utility Warehouse, Rebel Energy and some specialist suppliers operate in selected regions only. Even the Big Six set different unit rates per DNO area.
The 1 July 2026 cap rise affects each region by a slightly different amount because the standing-charge and unit-rate split varies by DNO — but the national picture is clear: electricity unit rates rise about 5% to 26.11p/kWh with a standing charge of 57.19p/day, and gas unit rates rise about 24% to 7.33p/kWh with a standing charge of 29.04p/day (typical direct-debit figures). Gas is doing almost all of the increase, so high-gas homes feel the rise most.
For privacy, we don’t publish individual postcode prices on this public page — the regional caps below are public Ofgem data, but supplier-specific quotes (which depend on your exact MPAN/MPRN) are returned only through the comparison form.
UK regional standing charges — July 2026
Indicative standing-charge ranges per region under the April–July 2026 cap. Numbers shift on 1 July 2026 (electricity standing charge moves to ~57p/day on a national-average basis) but the relative ranking between regions holds. These are the daily charges a standard-variable customer pays; fixed-tariff customers may pay a slightly different standing charge depending on the supplier.
| Ofgem region | Electricity SC | Gas SC | Typical postcodes |
|---|---|---|---|
| East Midlands | ~58p/day | ~30p/day | NG, LE, DE, LN |
| East England | ~60p/day | ~30p/day | CB, IP, NR, CO |

Indicative ranges from public Ofgem cap data, April–July 2026 cap period. The 1 July 2026 cap nudges the electricity side up by roughly 5%; gas unit rates rise about 24% while gas standing charges stay broadly flat. Personalised quotes via the comparison form.
Cheapest UK fixed tariffs — verified July 2026
These three fixes lead the UK market right now for a typical 2,700 kWh electricity + 11,500 kWh gas dual-fuel household. The final price depends on your postcode — the spread between regions on the same fix can be £50–£120/yr.
E.ON Next Fixed
~£1,602/yr typical — the cheapest 12-month fix in July 2026. Available in most postcodes. No exit fees in some regions.
~14% below the £1,862 July cap
Octopus 12M Fixed
~£1,632/yr typical. Available UK-wide, including Northern Scotland. Octopus’s customer-service reputation is the standout reason to pay the ~£30 premium.
~12% below the £1,862 July cap
EDF Essentials Plus
~£1,649/yr typical. Strong in London and the Southern regions. Loyalty discounts for existing EDF dual-fuel customers.
~11% below the £1,862 July cap
All three sit roughly £210–£260/yr below the July 2026 cap of £1,862/yr. Switching from a standard variable tariff to any of these before 1 July 2026 locks in that headroom for a year and means you skip the rise entirely. Run your postcode through the form to confirm which fix is actually cheapest for your DNO region.
Which suppliers serve your postcode?
Most of the Big Six — British Gas, EDF, E.ON Next, Octopus, OVO and ScottishPower — serve every UK postcode. Smaller suppliers often don’t.
UK-wide suppliers
British Gas, EDF, E.ON Next, Octopus, OVO, ScottishPower, SSE, Utilita, So Energy. All serve mainland UK including Northern Scotland and Wales. Northern Ireland is a separate market.
Regional / restricted suppliers
Utility Warehouse (selected DNO areas), Outfox the Market (most of GB except some Scottish postcodes), Rebel Energy (limited rollout), Good Energy, Ecotricity (green-only, UK-wide).
The 1 July 2026 cap rise — what your postcode pays
The headline +13.5% rise to £1,862/yr is a national average for a typical dual-fuel household paying by direct debit (up +£221 from £1,641, about £18 more per month). Prepayment customers move to roughly £1,812/yr and standard-credit (on-receipt) customers to about £2,005/yr. Your postcode matters: in Merseyside & North Wales the equivalent typical bill rises closer to £1,930/yr; in the East Midlands closer to £1,780/yr. Around 40% of accounts are on fixed tariffs and are protected for the duration of their contract — only standard-variable (price-capped) customers see the rise on their July bill.
Locking in a fix today (E.ON Next Fixed at ~£1,602/yr, Octopus 12M Fixed at ~£1,632/yr, EDF Essentials Plus at ~£1,649/yr) means you skip the entire July rise and avoid any further cap moves until at least summer 2027. The next cap review is 1 October 2026: Cornwall Insight currently forecasts the October cap at around £1,899/yr (on a current-TDCV basis), so prices are expected to edge up again rather than fall back. Comparing now, before 1 July, captures the cheapest deals while they are still below the new cap.
Run your postcode through the form to confirm which of these fixes is actually cheapest for your DNO region in July 2026, and by how much it beats your July cap.
Switching by postcode — step by step
- Find your postcode and have a recent bill ready (for your annual kWh figures).
- Enter both into the comparison form — we pull every supplier serving your DNO area.
- Review the top three tariffs ranked by total annual cost (not just unit rate).
- Check exit fees on the winning tariff — most July 2026 fixes have £50–£75 per fuel.
- Confirm online; supply switches in 5 working days under the Switch Guarantee.
- Take a meter reading on 30 June so the cheaper April–June cap covers your usage up to that date, then submit a closing read to your old supplier.
Frequently asked questions — cheapest energy by postcode (July 2026)
Why does my energy tariff depend on my postcode?
Three reasons: Ofgem sets 14 regional price caps, not one national cap; your DNO charges a different daily network fee depending on where you live (ranging from ~58p/day in the East Midlands to ~70p/day in Merseyside & North Wales for electricity in July 2026); and several suppliers don’t operate UK-wide. The cheapest tariff in IV1 is rarely the cheapest in EC1. The comparison form resolves all three by querying your exact DNO area.
What is the cheapest UK energy tariff right now (July 2026)?
For most postcodes E.ON Next Fixed at ~£1,602/yr (typical dual-fuel) is the lowest 12-month fix in July 2026. Octopus 12M Fixed at ~£1,632/yr and EDF Essentials Plus at ~£1,649/yr come next. Final ranking varies by DNO region — the cheapest national tariff isn’t necessarily cheapest where you live. Confirm via the comparison form.
How much will the July 2026 price cap rise cost me?
For a typical standard-variable dual-fuel customer the headline rise is £221/yr (+13.5%), to £1,862/yr from 1 July 2026 — about £18 more per month. Your postcode matters: in Merseyside & North Wales the equivalent bill is closer to £1,930/yr; in the East Midlands closer to £1,780/yr. Fixing now at ~£1,602–£1,649/yr avoids the rise entirely.
Does the July 2026 rise affect fixed deals?
No. The price cap only limits standard variable (default) tariffs, so the 1 July rise hits standard-variable customers only. If you are on a fixed deal — around 40% of UK accounts are — your unit rates and standing charges are locked until your contract ends, regardless of the cap. That is exactly why fixing before 1 July protects you from the increase.
Why is gas rising more than electricity in July 2026?
The increase is driven mainly by wholesale gas costs. From 1 July gas unit rates rise about 24% to ~7.33p/kWh, while electricity rises only about 5% to ~26.11p/kWh. Standing charges are roughly 29.04p/day for gas and 57.19p/day for electricity. Because gas does almost all of the work, homes with high gas use (older or larger properties) feel the rise most — another reason a postcode-and-usage quote beats a national average.
Should I fix before 1 July 2026, and will prices fall later in the year?
If the cheapest fix in your postcode is below the £1,862 cap — and the leading fixes are ~£1,602–£1,649 — fixing before 1 July locks in that saving and skips the rise. Prices are not expected to fall back soon: the next cap review is 1 October 2026, and Cornwall Insight currently forecasts the October cap at around £1,899/yr (current-TDCV basis), so a further small rise is more likely than a drop. Always compare your own postcode and usage before deciding.
Do all suppliers serve every UK postcode?
No. Big Six suppliers (British Gas, EDF, E.ON Next, Octopus, OVO, ScottishPower) plus SSE, Utilita and So Energy serve every mainland UK postcode. Utility Warehouse operates in selected DNO areas; Outfox the Market excludes some Scottish postcodes; Rebel Energy is still rolling out. The comparison form filters to suppliers that actually serve your address.
Does my postcode affect my standing charge specifically?
Yes, hugely. In July 2026 electricity standing charges range from ~58p/day (East Midlands) to ~70p/day (Merseyside & North Wales) — a ~£44/yr gap on identical usage. Gas standing charges range from ~28p/day (South West) to ~37p/day (Northern Scotland). Some tariffs have no standing charge but ~30% higher unit rates — only worth it under ~1,800 kWh/yr electricity.
Why don’t you show prices for my postcode directly on this page?
Supplier-specific quotes depend on your MPAN/MPRN and live tariff feeds that change daily — publishing them statically would mean stale prices within hours. The comparison form pulls live data only when you submit, so what you see is the actual July 2026 price you can switch to.
Lock in your postcode’s cheapest tariff before 1 July 2026
The £1,862 cap takes effect on 1 July. National headlines hide a regional spread of around £150/yr — the only way to see your real number is a postcode-based whole-of-market quote. It takes 60 seconds, and the leading fixes are still ~£210–£260/yr below the new cap.
