Frequently Asked Questions

It is easy to switch to Voltx in three simple steps:

1. Check your current supplier contract for its notice period and any termination or exit charges. Then get a quote from the Voltx Team.
2. Once you agree to the quote and sign the contract, give your current supplier 30 days� notice. We will register your supply start date.
3. On your transfer date, you will receive a welcome email with useful information about your supply. If you do not have a smart meter, provide an electricity meter reading within five days either side of your switch date / supply start date. This helps make sure your closing bill from your old supplier and opening bill from Voltx Power are accurate.

Additional charges: Climate Change Levy (CCL) is a government environmental tax on business energy and is charged on units used. DUoS (Distribution Use of System) charges may include availability (KVA / Agreed Supply Capacity), excess availability, reactive power, daily or standing charges, and unit rates. Unit rates may be split into Red, Amber and Green time bands set by the regional distribution company. Applicable charges depend on your meter type and product. Business energy VAT is generally 20%; qualifying businesses may be eligible for the 5% rate. The supplied information says average usage must be no more than 33 kWh per day or 1,000 kWh per month to qualify.

Meter read keys: C = Customer, E = Estimate, D = Deemed, R = Routine, S = Smart, O = Opening, F = Final, I = Initial, T = Reconcile Read.

Contract rates include the energy component, BSUoS and RCRC, Contracts for Difference (CFD), Feed-in Tariff (FIT), Renewable Obligation (RO), AAHEDC, Capacity Market, settlement charges, DUoS, TNUoS and, where applicable, Meter Operator (MOP), Data Collector (DC) and Data Aggregator (DA) charges.

Contract rates do not include excess capacity charges or reactive power charges where applicable to half-hourly meters, Climate Change Levy (CCL), or VAT.

If we do not receive an actual meter reading, we estimate your consumption based on your usage for that month. To avoid estimates, send us a meter reading and a photograph of your meter towards the end of your billing cycle. We appreciate an actual reading at least once every 4 to 6 months so we can understand your consumption pattern.

Electricity meters include electromechanical, electronic, smart and digital types. Your meter may be single-rate or multi-rate.

• Single-rate revolving disk: Read left to right and ignore figures in red or inside a red box. Example: 44955.3.
• Single-rate digital: Read left to right and ignore figures after the decimal point. Example: 44378.34.
• Single-rate dial: Dials turn in alternating directions. Read left to right, taking the lower number if a pointer is between two numbers. If it points directly at a number, record that number. Do not read the last dial on the right. Example: 44928.
• Two-rate revolving disk: Read both rows from left to right and ignore red figures. �Low� is night/off-peak; �Normal� is day/peak. Example readings: 251997 (Low) and 133995 (Normal).
• Two-rate digital: Record both readings from left to right and ignore figures after the decimal point. Example readings: 44378.34 and 65404.65.

Economy 7 meters record separate daytime and night readings. A discounted rate usually applies for seven hours each night.

Economy 10 offers ten discounted off-peak hours, usually three in the afternoon, two in the evening and five overnight. These meters record energy used during off-peak hours separately from daily usage.

Please provide a reading at the start of your contract and when you plan to change your arrangements with us. We appreciate an actual reading at least once every 4 to 6 months. Send your reading by:

• Telephone: +44 1908 772312
• Email: support@voltx.azurewebsites.net

Depending on your eligibility, we can install an AMR (automatic meter read) or SMETS2 smart meter for your electricity supply. Contact our Support Team to arrange a convenient installation date and time:

Our Credit Control team will contact you by email about non-payment. If you do not respond to the first email within a reasonable time, we will send another reminder. Your case may then be handed to a third-party payment collection agent.

If you still do not pay your energy bill, we may de-energise or disconnect your meter and require a security deposit before reconnecting it. We will apply for a warrant to enter your property and disconnect the supply. You will be responsible for the associated administrative charges as well as your energy bill.

Your current contract end date is shown on your bill. If you wish to renew with us, contact your Broker (TPI). If you are no longer working with your Broker, contact our Customer Service Team through our website or by phone.

Your contract end date is shown on each monthly bill, in the customer portal and in your contract. You are responsible for renewing on time. We will also send a renewal reminder 90 days before your contract ends. If you do not renew, Deemed Contract Rates will apply. Once you renew, the revised rates will apply. Add Voltx email addresses to your safe sender list so you do not miss important emails and updates.

Please let us know as soon as possible. Until we are notified, you may remain legally responsible for the supply and associated costs. On the day you move out, send us a closing meter reading and your new address so we can prepare your final bill.

For Change of Tenancy, email COT@voltxpower.co.uk.

Call us with a meter reading and tell us the date you moved in. Our Tenders Team will contact you to set up a new account in your business name.

It takes around 10 working days to change your billing and supply details to your new address. If you have been waiting longer than 10 working days, please call us.

Please contact our Accounting Team and they will help with your requirements.

Depending on your contract, you can pay by Direct Debit or BACS.

A credit note is issued if a bill is incorrect. For example, it may be issued if you have been overcharged for your energy. The credit note corrects the amount on the previous bill.

We offer fixed-rate business tariffs for 12, 24 and 36 months. Your unit rate (pence per kWh) and standing charge (pence per day) are fixed for the duration of your contract.

Yes. Our Green Fixed Tariff supplies electricity sourced from 100% renewable generation�solar, wind or hydro�certified through Renewable Energy Guarantees of Origin (REGOs).

You can switch at any time, but early termination charges apply if you end a fixed-term contract before it expires. These charges are based on the remaining term and consumption.

We will contact you before your contract expires. You can renew on a new fixed plan or move to our Deemed (Out of Contract) rates, which are usually higher.

The Nuclear Regulated Asset Base (RAB) Levy is a government-mandated charge introduced by the Low Carbon Contracts Company (LCCC) under the direction of DESNZ and Ofgem. It helps fund new nuclear generation projects that support the UK�s transition to low-carbon energy.

Visit Ofgem for information about the Nuclear RAB model.

The LCCC has mandated this charge to help fund new nuclear generation. All licensed electricity suppliers, including Voltx Power, must collect the levy from customers and remit it accordingly.

The supplied information states that the Interim Levy Rate (ILR) was �3.540 per MWh of electricity supplied from 1 December 2025 to 31 December 2025. The rate may change in the future.

It is a statutory charge, not a commercial one. It applies to energy consumers in Great Britain and is collected by energy suppliers.

Yes. The charge varies with the amount of energy you use.

The supplied information states that the RAB Levy Charge took effect from 1 December 2025.

No. As a government-mandated levy, Voltx Power cannot alter, remove or absorb it on behalf of customers.

The LCCC determines the charge level and total reserve amount on behalf of the government. Funds collected from suppliers finance the Nuclear RAB scheme, which supports nuclear power infrastructure development in the UK.

Yes. The LCCC or relevant regulatory authority may review and adjust the RAB Levy periodically.

MHHS is an industry-wide reform that changes how electricity consumption is recorded and used for settlement in Great Britain. Instead of relying mainly on estimated consumption patterns for many customers, the new system makes greater use of actual half-hourly electricity data where available.

MHHS aims to make electricity settlement more accurate and efficient. It will help suppliers better understand when electricity is used and support the development of more flexible energy tariffs and services in the future.

MHHS may provide opportunities for better visibility of electricity usage, more accurate industry settlement and new energy products designed around how and when businesses consume electricity. These benefits will depend on your meter type and the services available.

MHHS is being introduced gradually across Great Britain. Voltx Power plans to begin migrating customer electricity meters from 26 October 2026, with migration continuing in phases. The industry-wide meter migration deadline is 7 May 2027.

Yes. MHHS is an industry-wide change affecting domestic and non-domestic electricity customers, including customers with smart, advanced and traditional meters. The way consumption data is obtained may vary depending on the meter type.

Not necessarily. MHHS does not automatically require a meter replacement. Existing compatible meters can continue to operate. If your meter needs attention or an upgrade, Voltx Power will advise you.

You can still be included in MHHS. Traditional meters are supported under the new arrangements, although estimated consumption profiles may continue to be used where actual half-hourly data is unavailable. You should continue submitting meter readings as required.

If you have a traditional meter, please continue providing regular readings. If you have a smart or advanced meter, automatic readings may be available, but we may still request a reading if there is a communication or data issue.

MHHS migration is primarily a change to industry systems and settlement processes. It does not ordinarily involve interrupting your electricity supply. If a separate meter visit is required, we will communicate the arrangements.

Please contact Voltx Power if you suspect a meter communication issue. We may ask for a manual meter reading while we investigate and work with the relevant metering service provider.

MHHS does not automatically increase your electricity bill. Your charges will continue to depend on your contract, tariff, usage and applicable industry charges. Any future changes will be communicated in accordance with your contractual terms.

MHHS migration does not, by itself, mean that you need a new electricity supply contract. Your existing contractual terms continue to apply unless changes are made in accordance with the contract and applicable requirements.

Not necessarily. Half-hourly settlement and half-hourly pricing are different. If you are on a fixed-rate tariff, MHHS does not automatically convert it into a variable or time-of-use tariff. Your charges will follow your agreed tariff.

MHHS does not automatically change your billing frequency. You should continue receiving bills according to your existing billing arrangements unless Voltx Power notifies you otherwise.

Some industry identifiers and metering information may change as part of MHHS. For example, the MPAN top-line information may be updated, and MOP/DA/DC will be updated to Metering Services and Data Services. These changes do not necessarily mean your meter, supply point or rates have changed.

MHHS does not automatically remove an existing day-and-night or multi-rate tariff. Any changes to your tariff structure will depend on your contract and the metering arrangements applicable to your supply.

No. MHHS is intended to support a more efficient electricity system and may enable new tariff options over time, but individual bill savings are not guaranteed.

In most cases, no immediate action is required. Voltx Power will manage the industry migration process. Please keep your contact details up to date and continue providing meter readings where needed.

Voltx Power is introducing MHHS in phases. If you need information about your meter's migration status, contact our customer support team. We will communicate any changes that require your action.

Yes. The introduction of MHHS does not prevent you from switching electricity suppliers. Switching will continue under the applicable industry processes, including during the transition period.

If your business has several MPANs or sites, they may migrate to MHHS at different times. Voltx Power will manage each electricity supply point in accordance with the industry migration arrangements.

Voltx Power will work with relevant industry service providers to investigate and resolve migration issues. If an issue affects your meter readings or billing, we may contact you for additional information.

MHHS introduces new arrangements for using electricity consumption data for settlement. Access to detailed data is subject to applicable regulatory and data protection requirements, including rules that depend on customer and meter type.

Voltx Power handles personal data in accordance with applicable data protection laws and relevant energy industry requirements. Please refer to our Privacy Policy for further information.

No. MHHS applies to electricity market settlement and does not directly change your gas meter or gas supply arrangements.

If you have questions about your electricity meter, billing, contract or the MHHS transition, contact the Voltx Power customer support team at support@voltxpower.co.uk.
