January 2027 Price Cap Forecast

Element Forecast range
Overall annual figure £1,700–£1,900 (typical dual-fuel, direct debit)
Electricity unit rate 24p–26p per kWh
Gas unit rate 6p–7p per kWh
Electricity standing charge 55p–65p per day
Gas standing charge 30p–35p per day
Announcement date Expected late November 2026

These are estimates based on wholesale market forward prices in early 2026. The actual cap depends on wholesale costs closer to the announcement.

What Drives the Cap Level?

Factor Impact
Wholesale gas prices The biggest factor — UK electricity prices are heavily linked to gas prices
Wholesale electricity prices Directly affects the electricity unit rate
Network costs Maintaining the gas and electricity grid — typically rises with inflation
Policy costs Green levies, supplier obligations, warm home discount scheme
Supplier operating costs Staffing, IT, customer service
Supplier margin Ofgem allows a small profit margin per customer
Bad debt Cost of customer non-payment — higher in cost-of-living pressures

What Does the Cap Mean for Your Bill?

The “typical” household figure is based on Ofgem’s assumed average consumption:

Fuel Typical annual consumption
Electricity 2,700 kWh per year
Gas 11,500 kWh per year

Your actual bill will differ:

Household type Likely annual bill at £1,800 cap
1-bed flat, 1 person £1,100–£1,400
2-bed house, 2 people £1,500–£1,800
3-bed semi, family of 4 £1,800–£2,200
4-bed detached, family of 5 £2,200–£2,800
Electricity only (no gas) £700–£1,000
All-electric with heat pump £900–£1,400

Should You Fix or Stay on the Variable Cap?

Scenario Recommendation
Fixed deals available below forecast cap Fix — you lock in a lower rate
Fixed deals higher than current cap Stay on variable — benefit if prices fall
You want cost certainty Fix — your rate won’t change for the fix term
You want flexibility Variable — you can switch anytime without exit fees
You think prices will rise significantly Fix now before rates go up
You think prices will fall Stay on variable — the cap will drop to reflect lower wholesale costs

Current Best Fixed Deals vs Cap

Check comparison sites for the latest rates — the gap between fixed deals and the cap changes constantly:

Where to compare Website
Ofgem-accredited comparisons Uswitch, MoneySuperMarket, Compare the Market
Energy Helpline energyhelpline.com
Citizens Advice price comparison citizensadvice.org.uk/consumer/energy

Tip: A fixed deal 5%–10% below the forecast cap is generally worth taking. A fix more than 10% above the current cap is usually not worth it unless you believe prices will rise significantly.
