What Are Deemed Electricity Rates for Business? The 2026 Guide to New Premises

What if your first month in a new office cost you 40% more in overheads just because you forgot to sign a single piece of paper? When you move into a new premises without a pre-arranged contract, you’re automatically placed on a “deemed” tariff. You might be wondering, what are deemed electricity rates for business, and the simple answer is that they’re some of the most expensive prices on the UK market. For instance, while the average small business rate in late 2025 was around 26 p/kWh, some deemed day rates in early 2026 have climbed as high as 38.61 p/kWh.

It’s completely normal to feel stressed by the bureaucracy of a move, especially when you’re trying to tell the difference between a physical meter installation and a new supply contract. This 2026 guide will help you master the process of securing a new commercial connection so you can avoid the expensive traps of default pricing. We’ll break down the latest rates from suppliers like EDF and TotalEnergies, providing a clear path to move your business from expensive uncertainty to a stable, fixed-term deal.

Avoiding the Deemed Rate Trap When Moving Premises

Taking over the keys to a new commercial property is an exciting milestone, but it’s also the moment a high-stakes financial clock starts ticking. In the UK, energy supply is continuous. This means the lights will stay on when you walk in, but you aren’t on a competitive deal yet. Unless you’ve pre-arranged a contract, you’re automatically placed on a “deemed” tariff with the building’s existing supplier. This happens the second you become responsible for the site, regardless of whether you’ve spoken to the energy company or not.

Doing nothing is the most expensive decision a new business manager can make. Incumbent suppliers use your move-in date to maximize their profit margins, charging premium prices because they have no data on your credit history or energy usage patterns. By early 2026, the gap between these default rates and negotiated contracts has widened significantly. While a typical micro-business might secure a fixed rate around 25.8 p/kWh, deemed rates from major suppliers like TotalEnergies have reached 38.61 p/kWh for non-half hourly day usage. That’s a 50% markup just for failing to sign a contract.

What Exactly Are Deemed Electricity Rates?

A deemed contract is a default, non-negotiated agreement that exists by law. If you haven’t researched what are deemed electricity rates for business, you’ll find they are designed to cover the supplier’s risk for “uncontracted” customers. These tariffs are not subject to a strict price cap, unlike domestic energy. Suppliers have the legal right to charge these elevated prices until you either sign a new contract with them or switch to a different provider. Because you aren’t locked into a term, you can leave at any time, but you’ll pay a heavy price for that flexibility every single day you remain on the tariff.

The Move-In Window of Opportunity

Success begins with identifying the incumbent supplier at least 4-6 weeks before your tenancy starts. This lead time allows you to compare the market without the pressure of a looming bill. On your first day in the premises, taking a clear photograph of the meter reading is critical. This prevents the supplier from overcharging you for energy used by the previous tenant and provides the baseline data needed to secure a better deal. By acting quickly, you can transition from an expensive deemed rate to a competitive fixed-term contract within your first month, protecting your startup capital or operational budget from unnecessary drain.

New Connection vs. New Contract: Understanding the Process

Confusing a physical meter installation with a supply contract is a common headache for new business managers. While both involve your energy supply, they are entirely different processes. A new connection is essentially a construction project involving your local Distribution Network Operator (DNO) to lay physical cables and install a meter. Conversely, a new contract is an administrative step where you choose which supplier bills you for the energy used by an existing meter. If you skip this admin step, you’ll inevitably face what are deemed electricity rates for business, which are the high default prices charged by the building’s current provider.

The Meter Point Administration Number (MPAN) is the heart of this process. It’s a unique 21-digit code that identifies your specific electricity supply point. In 2026, administrative switches typically take between 5 to 14 days to complete. Physical connections are much slower, often requiring several months of lead time due to grid capacity and planning requirements. Consulting Ofgem’s official guidance can clarify the legal protections you have during these transitions.

Do You Need a New Meter Installation?

If you’re moving into a newly built warehouse or a site that has been completely redeveloped, you likely need a new physical connection. This requires an application to your local DNO, not just an energy supplier. The DNO handles the physical infrastructure, while the supplier provides the meter and the billing contract. Managing both parties can be overwhelming. A specialist business energy brokerage can coordinate with the DNO and your chosen supplier simultaneously, ensuring your power is live the day you open your doors.

Securing a Contract for an Existing Meter

For most businesses moving into existing premises, the hardware is already there. Your priority is the Change of Tenancy (CoT) process. This is the formal way to tell the current supplier that the previous occupant has left and you are now in charge. You can find your MPAN on the side of your meter or by calling your local network operator. It’s vital to remember that you’re never legally bound to the previous tenant’s energy provider. You have the right to shop around for a competitive fixed-rate deal from day one. Failing to do so simply leaves you stuck with the incumbent’s expensive default rates.

Choosing the Right Business Electricity Tariff for 2026

Once you’ve identified your MPAN and avoided the immediate trap of what are deemed electricity rates for business, your next move is selecting a tariff that matches your operational needs. Unlike domestic energy, business contracts are legally binding from the moment of agreement. There is no statutory “cooling-off” period. If you sign a three-year deal on a Monday, you’re committed to those terms by Tuesday. This makes your initial choice critical for long-term cash flow and budget stability.

The UK market is currently undergoing a major shift with Market-wide Half-Hourly Settlement (MHHS). This regulatory change means almost all businesses are moving toward more precise, time-of-use billing. Your bill consists of two main parts: the unit rate (what you pay per kilowatt-hour used) and the standing charge (a daily fixed fee for maintaining your connection). While some suppliers lead with low unit rates, they may offset this with high daily standing charges. You need to balance both based on your actual consumption profile to find the true best value.

Fixed-Rate Contracts for Budget Certainty

For most small businesses, farms, and charities, a fixed-rate contract is the gold standard for financial planning. It locks in your unit price for a set duration, usually between one and three years. This protects you from wholesale market spikes, which are expected to continue through 2026 as the grid modernises. While a three-year deal might have a slightly higher starting price than a one-year deal, the peace of mind against future inflation is often worth the premium.

Farms benefit significantly from these long-term locks. Agricultural operations often have seasonal peaks that make variable rates a gamble. By securing a fixed price, you can forecast your overheads with precision, even if national energy costs fluctuate during harvest. Charities also find this stability vital. It ensures donor funds are spent on their core mission rather than being swallowed by unpredictable utility bills.

Flexible and Green Energy Options

Larger operations with high consumption might consider “pass-through” or flexible tariffs. These allow you to buy energy in chunks or pay the current market rate, potentially saving money if you can shift your usage to off-peak hours. However, this requires active management and a high tolerance for market movement. It’s a strategy best suited for businesses with dedicated facilities managers.

Sustainability is also a major driver in the 2026 market. Many businesses now prioritise renewable energy backed by REGO (Renewable Energy Guarantees of Origin) certificates. Choosing a green tariff isn’t just about ethics; it’s a strategic move to meet ESG (Environmental, Social, and Governance) targets. Many corporate clients now demand these credentials from their suppliers. Aligning your energy procurement with these goals can actually help you win new business while contributing to a lower-carbon future.

A Step-by-Step Checklist for Your New Supply Setup

Setting up a new supply doesn’t have to be a bureaucratic nightmare. By following a structured path, you can exit expensive default billing quickly and focus on running your business. If you’re still asking what are deemed electricity rates for business, remember they are the “out-of-contract” prices you pay until you take action. These rates are significantly higher than standard deals. Taking control of your energy costs from day one is a matter of following four logical steps.

Phase 1: Information Gathering

Success starts with accurate data. Before you contact any suppliers, ensure you have the following information ready. This prevents delays and ensures your quotes are based on reality rather than guesswork.

• Locate your meter: Record the serial number and the MPAN. This 21-digit number is the unique identifier for your supply point. You can often find it on a sticker in the meter cupboard or by calling the local network operator.
• Take a move-in reading: Take a clear photo of the meter display on the day you take over the keys. This is your evidence to ensure you aren’t billed for the previous tenant’s usage.
• Estimate your usage: Gather your registered company details and a rough estimate of your annual consumption. If you don’t have previous bills, base this on the square footage of the premises or your planned equipment list.

Phase 2: Execution and Confirmation

Once you have your data, it’s time to move from the expensive default state to a competitive contract. This phase is about formal notification and market comparison.

First, identify your ‘deemed’ supplier. This is the company currently providing power to the building. You must notify them of your move immediately by submitting a formal Change of Tenancy (CoT) form. This officially ends the previous tenant’s liability and starts yours. However, don’t stop there. The incumbent supplier’s default rates are rarely the best choice for your bottom line.

Next, compare the market. Don’t just accept the first quote the current supplier offers. Use a specialist business energy broker UK to compare at least 10 different suppliers simultaneously. This ensures you find a rate that reflects the actual 2026 market value rather than a generic, high-margin price. Once you’ve selected a fixed-rate deal, sign the contract and arrange a Direct Debit. Most UK suppliers offer a discount for automated payments, and it ensures you never miss a bill.

Frequently Asked Questions

How long does it take to set up a new business electricity supply?

It typically takes between 5 to 14 days to complete the administrative switch for an existing meter. If you require a brand-new physical connection from the grid, the process is significantly longer and often involves several months of planning with your local Distribution Network Operator. Managing these timelines effectively ensures your business has power the day you open your doors without relying on expensive emergency tariffs.

Can I switch energy suppliers before I move into my new business premises?

You can and should arrange your new contract up to several months before your move-in date. Securing a deal in advance is the most effective way to avoid being charged what are deemed electricity rates for business by the building’s current supplier. By signing a fixed-rate contract early, you lock in your costs and ensure a smooth transition of billing responsibility from the very first day of your tenancy.

What is an MPAN and where can I find it for my new shop or office?

Your Meter Point Administration Number (MPAN) is a unique 21-digit code that identifies your specific electricity supply. You can find this number on a sticker attached to your meter box or by contacting your local network operator. If you have access to a previous bill for the property, the MPAN will be clearly displayed in a grid format, usually starting with the letter ‘S’.

Do I have to pay a security deposit to my new energy supplier?

Some suppliers may request a security deposit if your business is a new startup or has a limited credit history. This is a common practice used to mitigate the supplier’s risk. However, many providers will waive this requirement if you agree to pay by Direct Debit or provide additional financial information. A broker can help you identify which suppliers are most likely to offer a contract without demanding an upfront deposit.

What happens if I move into a property and the electricity has been disconnected?

If the supply has been physically disconnected, you must contact the local Distribution Network Operator or the building’s incumbent supplier to arrange a reconnection. You may need to provide a safety certificate from a qualified electrician before the power is restored. It’s vital to address this weeks before moving in, as restoring a disconnected supply involves technical site visits and administrative fees that can delay your opening.

Is it cheaper to get a combined gas and electricity deal for my business?

Combined gas and electricity deals don’t always result in a lower price for commercial customers. Unlike domestic energy, business gas and electricity are often quoted separately to find the most competitive rate for each fuel type. While managing one supplier is simpler, comparing separate contracts often leads to better overall savings, especially for operations with high consumption in one specific area, such as heated greenhouses or catering kitchens.

What information do I need to provide to get a business energy quote?

To receive an accurate quote, you need to provide your full business address, your MPAN, and your estimated annual energy consumption. If you don’t have previous usage data, you can estimate it based on the equipment you’ll be running or the square footage of the premises. Having your registered company number and bank details ready will also speed up the credit check and contract generation process.

Will my business electricity be cut off during the switching process?

No, your electricity supply will not be cut off during the switching process. The transition between suppliers is purely administrative, and the physical flow of energy remains constant. You won’t experience any downtime. The only change is the company that bills you. This allows you to safely move away from what are deemed electricity rates for business without any risk to your daily operations or customer service.
