Stricter net zero requirements, new metering rules, and major electricity network upgrades
For many UK businesses, renewable energy is becoming an increasingly important part of day‑to‑day decision‑making. Updates to legislation, ongoing changes in the energy market, and a stronger focus on carbon reporting mean that organisations of every size, from micro businesses to large multi‑site operations, are taking a closer look at how renewable energy fits into their plans.
It helps to understand the rules, planning requirements, and regulatory responsibilities that apply in 2026. These shape everything from the tariff types available to businesses, to the permissions required for installations at your business premises, to how energy suppliers certify renewable and zero carbon electricity.
This guide sets out the key areas UK businesses should be aware of before comparing business electricity, signing new energy contracts, or planning renewable projects, with practical considerations for organisations

The Climate Change Act 2008 remains the statutory foundation for UK climate targets. Amendments, including the 2019 regulation committing the UK to net zero by 2050, continue to govern the overall framework. Recent policy updates reinforce this trajectory, such as the 2025 Carbon Budget and Growth Delivery Plan.
In practice, the UK’s net zero framework shapes how energy suppliers, generators, and network operators plan and operate, even though the industry codes themselves do not explicitly prioritise low carbon generation. Decarbonisation pressures instead come from the Climate Change Act, legally binding carbon budgets, and policies such as the Net Zero Strategy and the UK Emissions Trading Scheme.
These measures influence market behaviour, so you are likely to see a continued increase in low carbon electricity options in retail markets, stronger policy focus on improving energy efficiency, and a broader range of commercial energy choices as suppliers respond to net zero requirements.
For businesses, the immediate impact tends to fall into three areas.
- First, you will see more green and renewable‑backed tariffs. These are becoming more common because carbon pricing and emissions targets encourage suppliers to offer options that let you match your usage with lower carbon electricity.
- Second, smart meters and better energy data are becoming more important. As the UK moves towards its mandatory net zero milestones, organisations need clearer insight into how much energy they use, and when, to support reporting and efficiency improvements.
- Third, the electricity network is undergoing major investment to support the shift to clean power. These upgrades are funded through regulated price controls, which can influence both the unit rate you pay and the standing charge on your business bill over time.

Permissions, planning, and grid connections for on‑site renewables
If you want cheaper electricity through self‑generation, you will likely consider rooftop solar PV, possibly alongside battery storage or heat pumps to support wider energy savings:
- Planning. Many commercial rooftop solar systems fall under permitted development, so they do not require a full planning application. However, listed buildings, conservation areas, and installations that significantly alter the roofline may still need consent. Rules also apply to panel height, roof edge clearance, and visual impact. If in doubt, ask your local planning authority early to avoid delays and unexpected requirements.
- Grid connection. Any new generator or battery system must be approved by your Distribution Network Operator. Most commercial systems require a G99 application before installation. Timelines vary depending on system size and local network constraints, and the DNO may require grid reinforcement, which can add cost. Early feasibility checks and complete application packs help keep projects on schedule.
- Metering and export. To track generation and export, you will need appropriate metering. Systems above 30 kW typically require an export meter if you plan to sell unused electricity back to the grid. To qualify for the Smart Export Guarantee, you must have a smart meter or another meter capable of recording half‑hourly data. Half‑hourly metering is becoming standard across business premises and is required for settlement from December 2026.
Well‑planned installations that integrate with reroofing or refurbishment can reduce labour costs, streamline permitting, and deliver significant savings over retrofit. Building‑integrated photovoltaic options are also growing, which can improve aesthetics and help meet business goals for ESG reporting.
Contracts for Difference, REGOs, and what they mean for your bills
Contracts for Difference (CfDs) are legally binding contracts between a renewable electricity generator (for example, a wind farm or solar farm) and the Low Carbon Contracts Company, which is a government‑owned body. The contract gives the generator a fixed price for the electricity it produces, known as a strike price. If the market price is lower, the generator is paid the difference. If the market price is higher, the generator pays back the difference.
Renewable Energy Guarantees of Origin (REGOs) are certificates that confirm that one megawatt‑hour of electricity was generated from a renewable source. Suppliers use REGOs to demonstrate the renewable content of their tariffs and to make claims such as “100% renewable electricity”.
What this means for your bills:None of these appear as separate charges on your energy bill. Instead, they influence how suppliers price their tariffs.
- CfDs help steady long‑term wholesale electricity prices.
- REGOs and granular‑matching options affect the cost and structure of renewable tariffs.
Any impact is included in the unit rate you pay, not listed as an additional fee.
More renewable generation in the system can also reduce exposure to volatile global gas prices, although any effect on business bills depends on wider market conditions.
Talk to an Energy ExpertBusiness energy contracts: what to check before you sign
Choosing the right supplier and contract type can be time consuming without a specialist. An experienced energy broker can compare business electricity from different suppliers, surface the latest prices, and explain the trade‑offs.
Key items to review:
- Tariff types and pricing. Check whether the tariff is fixed, flexible, or pass‑through, and look at the unit rate, standing charge, and how non‑commodity costs are applied. This helps ensure the pricing structure fits your business’s usage pattern and avoids unexpected costs later on. If you are unsure which structure fits your usage pattern, get advice before signing.
- Site status. If a site has ceased trading, or you are taking on new business premises, ensure the supply is correctly set up to avoid deemed rates. This means checking the latest bill for the MPAN and meter type, or using Find My Supplier if no bill is available, then confirming the supply status directly with the current supplier and asking whether any objection is in place.
- Green credentials. For zero carbon electricity claims, check the REGO position, any hourly matching, and whether renewable energy is from UK suppliers and generators. You can do so by asking the supplier for their fuel mix disclosure, REGO evidence for the tariff, and a plain‑English explanation of how their matching works. Most suppliers can confirm whether their REGOs come from UK‑based generation and whether the tariff uses annual matching or closer to real‑time matching.
Practical compliance for business premises
Even if you are not installing generation, most businesses still hit a few practical compliance steps. Here is what they involve, how to do them, and the direct benefits you can expect.
- Smart meters. Strongly encouraged for half‑hourly data, better forecasting, and tailored energy tariffs. They support energy efficiency projects and help verify reductions in electricity usage.
- Energy efficiency. Upgrades such as LED lighting, HVAC optimisation, building management systems, and power factor correction can reduce energy consumption and improve your position for future building standards.
- Heat solutions. Heat pumps and related technologies are becoming simpler to permit and install. They work best when paired with on‑site renewables and storage to cut peak grid import, reduce business gas consumption, and improve resilience.
- Portfolio management. If you manage multiple sites, consolidate your view of unit rates, consumption, and contract terms. Align renewals to simplify procurement and unlock better group purchasing, especially for larger businesses.

Costs in 2026: what is driving your business electricity bills
Your bill combines wholesale costs with non‑commodity elements such as network charges and policy levies. As more renewable energy enters the system, long‑term electricity prices should trend lower, although moving power around the grid will continue to influence the standing charge. Businesses that can shift demand to low‑cost periods, or that can self‑generate, are best placed to access the best deal.
One of the largest pressures in 2026 is the significant increase in Transmission Network Use of System (TNUoS) costs, which fund national grid infrastructure. These are expected to almost double from April 2026 and are commonly passed to businesses through higher standing charges.
Businesses can still take advantage of falling or stable wholesale prices if they choose suitable contract structures, but overall bill relief is limited by the growing fixed‑cost environment.
How a broker helps you get the right supplier, fast
Working with a reliable supplier matters, but comparing every offer across different suppliers is hard work. A good energy broker will:
- Scan up to date prices from multiple UK suppliers.
- Provide business electricity quotes that are specifically tailored to your business size, sector, and operating hours.
- Check contract terms, pass‑through components, and additional costs so you are not caught out.
- Align your procurement with your sustainability plan, including renewable energy, granular matching, and on‑site options.
- Manage switching, objections, and go‑live, which saves time and reduces risk.
Final thoughts
2026 is a year of structural change for business energy users. Renewable energy now sits closer to the centre of UK energy policy, so every organisation should be clear on how it affects their contracts, compliance responsibilities and long‑term pricing.
The key is to choose a renewables approach that matches your operating hours, load profile and carbon targets. Good procurement, stronger data from smart meters, and realistic planning for network and policy costs will be essential for cost control over the next few years.

View prices nowMost commercial rooftop installations fall under permitted development, but listed buildings and conservation areas may require approval. Always check with your local planning authority.
Solar PV remains the most popular, followed by battery storage and heat pumps. Your operating hours, energy consumption profile, and available roof space will determine the best fit.
On‑site generation can reduce your daytime unit rates and protect you from market volatility. Renewable tariffs may also offer competitive pricing with better carbon reporting options.
Grants, tax allowances, and local incentives change regularly. A broker or installer can explain what applies to your location, sector, and installation size.
Many do, but check the REGO position, whether the electricity is UK generated, and whether the supplier offers granular or hourly matching.
