What Is a New Business Energy Connection?
A new business energy connection is the process of establishing a permanent electricity or gas supply to a commercial premises that has never been connected before, or that requires a significant upgrade to its existing supply infrastructure.
This is different from switching business energy supplier, which involves changing who bills you for an existing supply. A new business energy connection involves physical infrastructure work, laying cables, installing meters, upgrading transformers, carried out by your local Distribution Network Operator (DNO) or gas network operator before any supplier can bill you.
New business energy connections are required in several situations. A new build commercial unit with no previous supply. A business expanding into a previously unoccupied industrial building. A site requiring a higher voltage or capacity connection than already exists. A temporary construction site supply. A rural business premises with no existing network connection nearby.
Understanding the distinction between the network connection and the energy supply is the most important starting point. Your DNO provides the physical infrastructure. Your business energy supplier provides the commodity, the electricity and gas you actually consume. These are two entirely separate commercial relationships and two separate contracts.
Types of New Business Energy Connection
Not every new business energy connection involves the same level of work or cost. The type of connection you need depends on what infrastructure already exists at or near your site.
Standard Connection
A standard connection applies where network infrastructure already runs close to your site and the work required is relatively straightforward. Your DNO connects your premises to the existing network using standard equipment. For electricity, this typically means a new cable run from the local distribution network to your site. For gas, it means a new service pipe from the main to your meter point.
Standard connections are the fastest and least expensive route. Most complete within 5 to 30 working days depending on the DNO and the complexity of the site work.
Bespoke Connection
A bespoke connection is required where the standard infrastructure cannot meet your requirements. This includes sites needing high-voltage connections, sites requiring significant network reinforcement, or sites located far from existing network assets.
Bespoke connections involve a full design and quotation process from your DNO and can take significantly longer to complete. For large commercial or industrial sites, the connection design and construction process can run from 3 to 12 months.
Temporary Connection
A temporary business energy connection provides a short-term supply for construction sites, events or seasonal operations. Temporary connections are quicker to establish but carry higher unit rates than permanent fixed-term supplies. Businesses should move to a permanent business energy connection as quickly as possible to avoid the cost premium of temporary supply.
The New Business Energy Connection Process
Whether you are connecting a small retail unit or a large industrial site, the business energy connection process follows the same broad sequence.
Step 1: Identify Your DNO
Your DNO is the licensed company responsible for the electricity distribution network in your area. There are 14 DNO regions across Great Britain. Your local DNO handles all new electricity connection enquiries and quotes. For gas, contact your local gas network operator — Cadent, Northern Gas Networks, SGN or Wales and West Utilities depending on your location.
Step 2: Submit a Connection Enquiry
Contact your DNO or gas network operator with details of your site address, the type of supply you need and your estimated maximum demand in kVA for electricity or cubic metres per hour for gas. The operator will assess what work is required and provide a formal connection offer.
Step 3: Review the Connection Offer and Costs
Your DNO or network operator will provide a formal written offer detailing the scope of work, the estimated timescale and the connection charge. For business energy connections, these charges can range from a few hundred pounds for a simple standard connection to tens of thousands of pounds for a bespoke high-voltage connection requiring significant network reinforcement.
You are entitled to request quotes from an Independent Connection Provider (ICP) as an alternative to your DNO carrying out the work. ICPs are licensed to carry out connection work on the distribution network and often provide faster or more competitive quotes for commercial connections.
Step 4: Accept the Offer and Pay the Connection Charge
Once you accept the connection offer, you pay the required connection charge and the DNO or ICP schedules the physical works. Timescales run from the date your payment is received and all necessary consents are in place.
Step 5: Arrange Your Business Energy Supply Contract
Before a meter can be installed at your new premises, a licensed business energy supplier must be appointed and a supply contract agreed. This is a firm requirement meter operators will not install a meter without a confirmed supplier in place.
This makes arranging your supply contract a critical path item, not an afterthought. Delaying this step delays your meter installation, which delays your go-live date. Contact Kilowatt Energy as soon as you have a confirmed connection date so we can run a whole-of-market comparison and have a competitive fixed-rate contract in place in time for your meter installation.
Step 6: Meter Installation and Go-Live
Once your supply contract is in place, your chosen supplier arranges meter installation through a Meter Operator (MOP). The meter is installed, your MPAN or MPRN is activated, and your supply begins from the agreed start date. You receive your first bill from your supplier based on your contracted tariff from day one.
New Business Energy Connection Costs: What to Expect in 2026
Connection costs vary significantly depending on your location, the type of connection required and the DNO or network operator involved.
| Connection Type | Typical Cost Range | Typical Timescale |
|---|---|---|
| Standard electricity connection (small commercial) | £500 to £3,000 | 5 to 20 working days |
| Standard electricity connection (medium commercial) | £2,000 to £15,000 | 10 to 40 working days |
| Bespoke high-voltage electricity connection | £15,000 to £150,000+ | 3 to 12 months |
| Standard gas connection (small commercial) | £500 to £5,000 | 10 to 30 working days |
| Bespoke gas connection (large commercial) | £5,000 to £50,000+ | 2 to 9 months |
| Temporary site supply | £300 to £2,000 | 5 to 15 working days |
Figures are indicative estimates based on 2026 market data. Actual costs depend on your specific site, DNO region, and scope of works.
How to Reduce Connection Costs
Connection charges are not always fixed. Several legitimate strategies can reduce the total cost of a new business energy connection.
Requesting multiple quotes from Independent Connection Providers alongside your DNO quote consistently produces competition that reduces overall costs. Designing your business energy requirements efficiently for example, specifying a lower kVA demand that still meets your operational needs reduces the infrastructure specification and therefore the connection charge. Timing your connection to avoid peak DNO workload periods can also reduce both cost and timescale.
Supplier New Connection Fees: A Hidden Cost Worth Comparing
Once your DNO connection is in place, your chosen supplier arranges the meter installation through a Meter Operator. What many businesses do not realise is that some suppliers pass the cost of this new connection commissioning and meter installation directly to the customer, while others absorb it entirely.
New connection fees charged by suppliers vary significantly:
| Fee Type | Typical Range |
|---|---|
| Meter installation/commissioning fee | £0 to £350+ |
| New connection admin fee | £0 to £150 |
| Smart meter installation (HH meters) | £0 to £500+ |
Some of the largest business energy suppliers charge new connection fees as standard. Others, including a number of competitive challengers in the business energy market, offer new connections with no installation or commissioning charge.
Over a 2 or 3 year contract, a £350 connection fee is a relatively small sum. But for a business opening multiple sites, or for a business where cash flow in the early months is tight, this is a real and avoidable cost.
Kilowatt Energy compares new connection fees alongside unit rates and standing charges when presenting market options to new connection customers. We identify which suppliers are currently offering zero-fee new connections without sacrificing competitive unit rates, and we present the total cost of supply over your full contract term so you can make a fully informed decision.
Choosing Your Business Energy Supplier for a New Connection
Once you are ready, choosing the right supplier is the most important financial decision you will make for your new site. The business energy market has no price cap. The rate you agree on your first contract sets your cost baseline for the entire contract term.
New business energy connections are an opportunity to approach the market without the constraints of an existing contract. You are not switching; you are choosing from scratch. That means no exit fees, no notice periods, and no switching objections from an incumbent supplier.
The key factors when selecting a business energy supplier for a new connection:
Consumption Estimate Accuracy
Suppliers price new connections on an estimated annual consumption figure. An overestimated consumption can push you into a higher tariff band. An underestimated consumption can result in higher unit rates when your actual usage exceeds the quoted profile. Work with a broker who can help you build an accurate consumption estimate based on your business type, trading hours and equipment profile.
Contract Length
A new business is often tempted by short 1-year contracts for flexibility. In a volatile wholesale market, a longer 2 to 3 year fixed contract locks in today’s competitive rates and protects against further increases. Read our wholesale vs fixed business energy guide for a full explanation of how to make this decision.
Standing Charges
For a new business energy connection, standing charges matter because your consumption in the first few months may be lower than your steady-state operations. A supplier with a high daily standing charge and a low unit rate may cost more in the early months than one with a balanced tariff structure. See our commercial energy comparison guide for a breakdown of how to read a business energy quote.
New Connection Fees
As noted above, some suppliers charge a one-off connection or commissioning fee, while others do not. Always compare the total cost of supply unit rate, standing charge and any one-off fees rather than unit rate alone.
Green Energy Requirements
If your business has sustainability commitments or ESG reporting obligations, confirming that your supply is backed by REGOs (Renewable Energy Guarantees of Origin) from day one sets the right foundation for carbon reporting.

FAQs: New Business Energy Connection
Q: How long does a new business energy connection take in 2026?
A standard commercial electricity connection takes between 5 and 40 working days from acceptance of the connection offer. Bespoke connections requiring significant network reinforcement or high-voltage infrastructure can take 3 to 12 months. Gas connections follow similar timescales depending on complexity and location.
Q: Who is responsible for the new business energy connection, the DNO or my supplier?
The physical network connection is the responsibility of your DNO or an Independent Connection Provider. Your business energy supplier is responsible only for billing you for the energy you consume once the connection is live and the meter is installed. These are two entirely separate relationships and two separate commercial agreements.
Q: Can I choose my own business energy supplier for a new connection?
Yes. You are completely free to choose any licensed business energy supplier for your new connection. You are not obliged to use the default supplier connected to your area’s network. Running a whole-of-market comparison before your connection goes live ensures you start on the most competitive rate available. Use our commercial energy comparison to see what the market currently offers.
Q: Do I need a supplier contract before my meter is installed?
Yes. A meter operator will not install a meter at a new premises without a confirmed supply contract in place. Arranging your business energy supply contract is therefore a critical step that must happen before meter installation, not after. Build this into your project timeline from the outset.
Q: Do suppliers charge a fee for new connection meter installation?
Some do, and some do not. New connection commissioning and meter installation fees vary from zero to several hundred pounds depending on the supplier. Kilowatt Energy compares these fees alongside unit rates and standing charges so you can see the true total cost of each option before committing.
Q: What is an Independent Connection Provider and should I use one?
An Independent Connection Provider (ICP) is a licensed company that can carry out connection work on the distribution network as an alternative to your DNO doing the work. ICPs are often faster and more competitively priced than DNOs for standard commercial connections. Requesting a quote from an ICP alongside your DNO quote is always worth doing for medium to large connections.
Q: How do I find out which DNO covers my area?
Enter your postcode on the Energy Networks Association website or contact Kilowatt Energy and we will identify your DNO as part of our free new connection support service.
