Business Energy Change of Tenancy Process: The 2026 Essential Guide

What if your next move was the secret to cutting your overheads by 30% or more? While most directors see moving day as a logistical headache, it’s actually a legal “reset button” for your utility costs. Managing the business energy change of tenancy process correctly means you can walk away from expensive legacy agreements and start fresh from day one.

We understand that the administrative burden of notifying multiple suppliers feels overwhelming, especially when you’re worried about being disconnected on move-in day. It’s natural to feel anxious about falling onto “deemed rates.” These are notoriously expensive; for instance, some 2026 electricity rates have reached 38.61 p/kWh for businesses left without a formal contract.

This guide will show you how to master the transition to ensure a seamless flow of power and gas while securing competitive market rates immediately. You’ll learn how the REC Schedule 33 regulations protect your timelines and which specific documents you need to prove occupancy. This is your path to taking full control of your new site’s energy procurement with confidence.

What is the Business Energy Change of Tenancy (CoT) Process?

At its core, a Change of Tenancy (CoT) is the formal process of updating the legal responsibility for energy supply at a commercial premises. It’s the moment the baton passes from one business entity to another. While it sounds like a simple change of address, it’s actually a vital legal “reset” for your utility bills. Getting the business energy change of tenancy process right ensures you aren’t paying for power used before you arrived or after you’ve left.

This process isn’t just for moving day. It applies to several scenarios, including property sales, the signing of a new contractual arrangement, or even instances of bankruptcy and insolvency. In every case, there are two distinct phases you need to manage:

• The Moving Out Phase: Notifying your current supplier that you’re vacating and providing a final meter reading to close your account.
• The Moving In Phase: Registering as the new occupier and securing a new contract to avoid expensive default rates.

Why CoT is Different for Businesses

Domestic energy moves are relatively straightforward. You can often carry your account with you or close it with a single phone call. Business energy is different because contracts are tied to the specific legal entity at a specific site. They don’t follow you to a new location automatically. If you move from Site A to Site B, your contract for Site A terminates, and you must start fresh at Site B. The new tenant has a legal obligation to secure their own supply. You don’t want to rely on whatever the previous tenant had in place, as those terms died the moment they moved out.

The “Freedom Window”: Why Timing is Everything

We view the business energy change of tenancy process as a strategic “freedom window.” Usually, commercial energy contracts are notoriously difficult to exit, often requiring months of notice. A move changes everything. It’s a rare opportunity to terminate a restrictive contract without the usual penalties. You can choose any supplier and any tariff the moment you take over a site.

Speed is your best friend here. Under the REC Schedule 33 rules introduced in June 2025, suppliers have 10 working days to review your evidence. If you delay, you’ll be placed on “deemed rates.” These are the most expensive tariffs in the market. By April 2026, some electricity day rates reached 38.61 p/kWh. Acting quickly prevents these costs from draining your budget during an already expensive move.

Step-by-Step: Managing Your Energy When Moving Business Premises

Executing a successful move requires precision. To ensure you don’t pay a penny more than necessary, you must follow a chronological timeline. Treating the business energy change of tenancy process as a series of scheduled tasks prevents administrative errors that lead to overcharging. Here is your operational roadmap for a smooth transition.

• Step 1: Notify your current supplier. Aim to do this at least 30 days before your move-out date. While some contracts allow for shorter notice, 30 days is the industry standard to ensure your account is flagged for closure correctly.
• Step 2: Capture final meter readings. On the day you vacate the premises, take clear photos of your gas and electricity meters. Photo evidence is your primary defense if a supplier disputes your final usage.
• Step 3: Provide a forwarding address. Your supplier needs a place to send the final “reconciliation” bill. This ensures you receive any credit due to you and prevents debt collection issues at your old site.
• Step 4: Identify the incumbent supplier. As soon as you get the keys to your new site, find out who currently supplies the power. You are technically their customer the moment you take occupancy.
• Step 5: Compare the market. Don’t settle for the incumbent’s default rates. Use this time to compare business energy tariffs and secure a contract that fits your new operational budget.

Providing Evidence of Your Move

Suppliers won’t simply take your word for it. To prevent fraud, they require specific documentation to prove a change of occupancy. You’ll typically need to provide a signed lease agreement, a TR1 (Transfer of Whole of Registered Title) form, or a formal letter from your solicitor. Under the REC Schedule 33 standards introduced in June 2025, suppliers must review this evidence within 10 working days. Ensure all signatures are clear and dates are legible; any ambiguity can reset the clock and keep you on expensive rates for longer.

Handling New Build Premises

Moving into a brand-new facility presents unique challenges. You won’t have a previous tenant’s bill to reference, so you’ll need to locate your MPAN (Meter Point Administration Number) for electricity or MPRN (Meter Point Reference Number) for gas. These are often found on the site’s developer hand-over pack. If a meter hasn’t been installed yet, you’ll need to contact the regional distributor to register the connection. This part of the business energy change of tenancy process can take several weeks, so start the registration as soon as the lease is signed to avoid move-in delays.

The Cost of Silence: Avoiding Deemed Rates and Overcharging

Silence is the most expensive mistake you can make during a move. If you take over a new premises and start using gas or electricity without first agreeing to a contract, you are automatically placed on what the industry calls “deemed rates.” This isn’t a penalty in the legal sense, but the financial impact certainly feels like one. These rates are designed to be temporary, yet they often cost two or three times more than a standard fixed-term tariff.

To put this in perspective, consider the market data from April 2026. TotalEnergies Gas & Power set their deemed electricity rates for non-half-hourly meters at 36.26 p/kWh for a single rate. Their deemed gas rate was 10.91 p/kWh with a daily standing charge of 230 pence. For a medium-sized office or a busy farm, staying on these rates for even a single month can add hundreds, if not thousands, of pounds to your initial moving costs. The business energy change of tenancy process is your only shield against these inflated prices.

Why Suppliers Use Deemed Rates

Suppliers operate under a regulatory framework that allows them to charge higher prices for “uncontracted” sites. From their perspective, they are supplying energy to a business with no credit history or commitment, which represents a higher risk. Unlike the domestic market, the business energy sector has no government-mandated price cap. This means suppliers are free to set deemed rates at levels that reflect the current wholesale market volatility plus a significant margin. The only silver lining is that these contracts have no fixed term. You aren’t “locked in,” which gives you the power to walk away the moment you find a better deal.

How to Transition to a Competitive Tariff

You can exit a deemed contract with zero notice period. This is a critical piece of leverage. While the incumbent supplier might offer you a “renewal” contract, it’s rarely the most competitive option in the wider market. To take control, you should engage a specialist business energy brokerage to scan the market for you. This allows you to compare multiple suppliers simultaneously rather than doing the legwork yourself.

To make this happen, you’ll need to provide a “Letter of Authority” (LoA). This simple document gives your broker the legal right to speak to suppliers on your behalf and gather the data needed for an accurate quote. Don’t feel pressured to accept the first offer the incumbent supplier sends your way. Because you are in that “freedom window” mentioned earlier, you have the absolute right to switch to a more affordable provider immediately. Using the business energy change of tenancy process to move straight onto a fixed-term contract is the most effective way to protect your bottom line from day one.

Your Change of Tenancy Checklist: Moving In vs. Moving Out

A successful transition relies on accurate data. While the business energy change of tenancy process involves several parties, your role is to provide the evidence that anchors the timeline. Missing a single reading can lead to months of disputed billing. Follow this structured checklist to ensure a clean break from your old site and a cost-effective start at your new one.

When Moving Out:

• Provide your final meter reading on the exact day your lease ends.
• Confirm the date of your lease end or property sale with a solicitor’s letter or TR1 form.
• Share your new contact details so the final reconciliation bill reaches you.
• Keep your Direct Debit active until the final bill is paid. Cancelling it too early often triggers automated debt collection letters, which can damage your business credit score.

When Moving In:

• Take a meter reading the moment you get the keys. This is your “Day One” baseline.
• Identify the previous tenant’s name if possible. This helps the supplier locate the correct account in their system.
• Locate your MPAN (Electricity) and MPRN (Gas) numbers. These unique identifiers are usually found on a sticker on the meter or in the site’s technical pack.

Specific Guidance for Farmers and Large Estates

Managing agricultural energy is rarely a one-meter job. Farms often have multiple meters across various barns, outbuildings, and residential dwellings. During the business energy change of tenancy process, you must identify “related meters.” These are separate meters that are linked under a single supply point. If you miss one, you could remain liable for the standing charges long after you’ve handed over the land. Additionally, check if your new site qualifies for Climate Change Levy (CCL) exemptions. Many agricultural processes are eligible for reduced rates, but these aren’t applied automatically; you must claim them.

Guidance for Charities and Non-Profits

Charities frequently overpay because they assume their status carries over to a new premises. It doesn’t. You must submit a fresh VAT declaration form to the supplier at your new site to ensure the 5% reduced VAT rate is applied. Without this, you’ll likely be charged the standard 20% rate. Ensure your registered charity address is updated with the supplier immediately to prevent correspondence from going missing. If you want to ensure these details are handled correctly from the start, you can get expert help with your charity energy move to avoid administrative errors.

Frequently Asked Questions

Will my power be cut off when I move into a new business premises?

Supply is almost never disconnected during a change of occupier. You’ll move onto a “deemed contract” with the existing supplier the moment you take possession of the keys. This ensures you have light and heat from day one, though you’ll be charged at the supplier’s highest rates until you agree to a formal fixed-term contract.

How long does the business energy change of tenancy process take?

Under the REC Schedule 33 regulations introduced in June 2025, suppliers must review your tenancy evidence within 10 working days. If they require further details, they have an additional 10 working days after receiving your evidence to make a final decision. It’s best to start the business energy change of tenancy process as soon as your lease is signed to avoid any administrative delays.

Do I have to stay with the current energy supplier at my new property?

You have no legal obligation to stay with the incumbent supplier. A change of tenancy acts as a reset button, allowing you to switch to any provider without the usual notice periods. This is your best opportunity to bypass expensive default rates and secure a market-leading tariff that fits your specific business budget.

What documents do I need to provide for a Change of Tenancy?

Suppliers typically require a signed lease agreement, a TR1 form for property purchases, or a formal letter from your solicitor. These documents must clearly show the move-in date and the names of both the outgoing and incoming parties. Ensuring these signatures are legible helps the supplier process your request within the standard 10-day window.

Can I change my business energy supplier before I move in?

You can arrange a new contract in advance, but it won’t go live until the day you legally take over the premises. We recommend comparing the market as soon as your move is confirmed. This allows your new supplier to be ready to take over the meter the moment you move in, preventing you from ever paying a day of expensive deemed rates.

What happens if the previous tenant left an unpaid energy bill?

You aren’t liable for the energy debt of a previous occupant. The energy contract is tied to the legal entity, not just the physical building. By providing a clear meter reading from your first day of occupancy, you create a “clean break” that ensures the supplier bills the correct party for the correct period of usage.

Is there a fee for changing my business energy tenancy?

Suppliers don’t usually charge a fee to process a standard change of tenancy. However, you should check for administrative charges if you’re requesting a new meter installation or a physical connection at a brand-new site. For most existing commercial properties, the business energy change of tenancy process is free to complete, though the cost of the energy itself will be high without a contract.

How do I find out who the current energy supplier is at my new site?

The quickest way is to ask the landlord or the previous tenant for a copy of a recent bill. If that isn’t possible, you can find your electricity supplier by contacting your regional Distribution Network Operator (DNO). For gas, the national “Find My Supplier” tool can identify the registered shipper using your property’s MPRN number.
