Labour Budget 2025: What It Really Means for UK Energy and Why Businesses Must Prepare Now
The Chancellor’s Budget has landed, and while most headlines focus on EV taxes and nuclear investment, the real story sits deeper: the UK’s energy market is being structurally reshaped and businesses across the UK will feel the impact long before 2026.
From the end of ECO funding to changes in the Renewables Obligation, new EV levies, and a renewed push for nuclear, this Budget signals a long-term shift in how the UK pays for and produces energy.
For Energy Oasis clients in manufacturing, logistics, hospitality and agriculture, the question is simple:
Will this Budget lower your bills or increase them?
What can you do now to stay ahead of rising costs?
Let’s break it down.
£150 Off Energy Bills, But Who Pays Instead?
The Government announced that typical households will save around £150 on their energy bills from April 2026. Sounds positive — but this change hides a major structural shift.
Here’s what’s really happening:
ECO funding ends completely on 31 March 2026
75% of the Renewables Obligation cost is moved off electricity bills and into general taxation
This removes around £154 of policy cost from a typical bill
For households, that’s a direct saving.
For businesses?
There is no guarantee your savings will match this.
Most non-household tariffs involve:
bespoke passthrough charges
contracted rates
capacity and DUoS charges
supplier hedging strategies
These are not governed by the domestic price cap, meaning:
👉 Businesses may not see the same level of relief, or any, depending on procurement arrangements.
If you're on a fixed corporate contract, your supplier may not adjust your tariff until renewal.
This is exactly why an Energy Procurement Review is now essential in 2026.
The Business Reality: Policy Costs Down, Infrastructure Costs Up
While the Budget removes some social and environmental levies from bills, it also signals larger long-term grid and generation investment:
£3.8bn for the Renewables Obligation (short-term only)
Major nuclear financing and SMR development
National Grid connection reforms and capacity expansions
These investments ultimately end up in:
Transmission charges (TNUoS)
Distribution charges (DUoS)
Capacity Market costs
Balancing Services Use of System charges (BSUoS)
Meaning for many businesses:
👉 Energy bills may become less predictable even as policy costs fall.
This is why reducing your demand is now the only strategy that guarantees lower bills.
EV Tax Changes: Businesses With Fleets Will Pay More
The headline-grabbing announcement was the new Electric Vehicle Excise Duty - a pay-per-mile system starting 2028:
3p per mile for full EVs
1.5p per mile for plug-in hybrids
This affects:
site vehicles
logistics fleets
maintenance vans
hotel and leisure EV courtesy fleets
agricultural EV equipment
While EV infrastructure gets a capital boost, OPEX for electric fleets will rise.
Fleet operators will need:
on-site charging
solar generation
battery optimisation
smart scheduling
Energy Oasis already supports this for logistics and manufacturing sectors (case study internal link: WM Armstrong).
Warm Homes Plan & Insulation Spend - Good for Households, Limited for Businesses
Households get meaningful support:
Insulation
Boiler upgrade extensions
Expanded heat pump funding
But business premises are not included.
This leaves commercial buildings facing:
rising heating costs
higher standing charges
stricter EPC requirements
The coming two years will see major EPC tightening. The only viable response for businesses is to cut heat loss and reduce electrical demand.
For most firms, LED upgrades and intelligent controls remain the fastest way to achieve EPC and CIBSE compliance.
Industrial Support Schemes Show a Clear Message: Reduce Your Consumption
From 2027, the British Industrial Competitiveness Scheme will reduce electricity costs by £35–£40/MWh for certain manufacturing sectors.
But the conditions are revealing:
Firms must demonstrate:
high energy intensity
participation in efficiency measures
clear decarbonisation plans
Meaning:
👉 Businesses that cut consumption will qualify for the most relief.
👉 Those who do nothing will fall behind.
Energy Oasis can prepare the energy audits and modelling required for eligibility.
Grid Chaos Continues But the Budget Hints at Solutions
The government acknowledged the elephant in the room: “Grid connection delays are one of the biggest blockers to growth.”
The reforms include:
new connection queue rules
greater use of self-build options
flexible connection arrangements
For businesses planning solar or EV infrastructure, this means:
👉 Projects that include intelligent load management (batteries + controls) will move faster through the queue.
This is precisely where Energy Oasis delivers value through grid-aware designs.
So… Will Energy Bills Fall?
Short Answer: Unlikely. But You CAN Control Your Consumption.
Household bills will fall slightly.
Business bills will remain volatile.
The grid will become more expensive.
Infrastructure levies will rise.
EV fleets will cost more to operate.
Policy costs will go down, but wholesale volatility remains dominant.
The only consistent strategy for businesses is:
Reduce what you need from the grid.
Generate what you can on-site.
Store what you produce.
Manage what you use.
That is the core message buried inside the Budget.
What Should Businesses Do Now?
-
Policy savings won’t show up unless your tariff is renegotiated. Usage reduction is the only reliable way to cut costs.
-
Suppliers will use this moment to reprice contracts.
-
LED + controls = 50–80% lighting reduction.
-
Grid and connection costs are only going one way: up.
-
Many require technical modelling, which we provide.
Take Control Before the Next Price Shock
The Budget won’t stabilise the energy market.
But it makes one thing absolutely clear:
👉 Businesses that reduce consumption will pay less.
Businesses that wait will pay more.
