A farm electricity renewal can shape your costs for years. We know which parts of an offer matter, which questions to ask, and where costly terms can hide. Use this clear check before you sign.

Before renewing a farm electricity contract, check the meter details, yearly use, unit rates, standing charges, fixed and variable costs, contract length, end terms, broker fees, taxes, and support. Compare the full yearly cost and get every promise in writing.

A cheap unit rate may not mean a cheap contract. Read on to learn the nine checks, how to compare quotes fairly, and how to protect your farm from a poor deal.

Before signing, compare prices, contract terms and supplier conditions to help protect your farm from avoidable costs. Click the button below to explore your Farm Electricity Contract Renewal options.

Farm Electricity Contract Renewal: 9 Things to Check Before You Sign

Farm electricity is not like a simple home bill. A farm may use power for milking, cooling, drying, pumping, lighting, heating, packing, workshops, and electric vehicles. Some of this work cannot stop when prices rise. A missed milking or failed cold store can cost far more than the power itself.

That is why a renewal needs more than a quick look at pence per kilowatt hour, or kWh. The best contract is the one that fits the way your farm works. It should give a fair total cost, clear rules, and enough certainty for your cash flow. Our guide to choosing the best business energy for farms explains how farm type, seasonal demand and operating hours affect the wider choice of tariff.

Start early. Gather at least 12 months of bills and make sure you understand the charges on each business energy bill.  If your use changes by season, 24 months is better. Note any new kit you plan to add, such as a heat pump, grain dryer, robot, battery, or charger. Also note kit you may remove.

Then make these nine checks.

Check every meter and MPAN

List every electricity meter on the farm. Match each meter serial number to the right building and bill. Find the Meter Point Administration Number, or MPAN, for each supply. This long number tells the market which electricity point is yours.

Check the meter type and whether it sends readings every half hour. Ofgem says some business supplies with MPAN profile numbers 05, 06, 07, or 08 use half-hourly readings. Ask the supplier to confirm the data it used for the quote. If a meter has no recent bill or its supplier is unclear, follow these steps to find out who supplies your business electricity before requesting renewal quotes.

Check your real use and load pattern

Do not accept a quote based only on an estimate. Add the kWh used in the last full year. Then look at when you use it. A dairy farm may have two large peaks each day. A grain farm may use most power after harvest. A poultry unit may need a steady load all year.

Adjust the forecast for known changes. Keep two figures: normal use and high use. Price both. A low quote can turn dear if it assumes less power than the farm will need.

Check the full unit rate

The unit rate is the price for each kWh. Yet the number in large print may not include every part of the cost. Ask which parts are fixed for the full term and which parts can change.

A “fixed” business contract may fix the energy part but allow some network, policy, meter, or tax costs to move. Ofgem also warns that some fixed-rate contracts contain a condition that lets the supplier change the rate. Read the price-change clause, not just the product name. The distinction is explained further in our guide to fixed versus variable business energy contracts.

Check standing and capacity charges

The standing charge is paid each day, even when little power is used. Multiply it by 365 and add it to the yearly cost. Do this for every meter.

Large or half-hourly supplies may have capacity charges. Capacity is the agreed level of power the network keeps ready for you. Too little can cause extra charges or limit new kit. Too much may mean paying for capacity you do not need.

Check what is fixed and what can pass through

Suppliers face costs beyond buying electricity. These can include network, balancing, meter, policy, and market costs. A fully fixed offer aims to hold more of them steady. A pass-through offer lets named costs move and sends the change to you.

Ask for a list with two columns: fixed and variable. Ask how often variable charges can change, how you will be told, and whether there is any cap. If the answer is vague, the future bill is vague too.

Check the contract length and start date

Business electricity contracts can run for several years. Ofgem says they can last up to five years, and most suppliers will not let a business switch before the end. A long deal can give certainty, but it can also lock the farm into an unhelpful rate or service.

Confirm the exact start and end dates. Make sure the new contract starts as the old one ends. A gap may place the supply on an out-of-contract or deemed rate. These rates can be higher and can change.

Check renewal, exit, and change terms

Read what happens at the end. Does the deal roll on, move to an out-of-contract rate, or become deemed? Note any notice window and the way notice must be sent. Keep proof that it was received.

Do not rely on a cooling-off period. Ofgem states that there is no cooling-off period after a business energy contract is agreed, even when the agreement is made by phone. Treat a spoken “yes” as a serious act. If you intend to leave rather than renew, check the required notice, evidence and final-account steps in our guide to cancelling a business energy contract.

Check broker fees and authority

A good broker can save time and explain a hard market. The service is not free. A broker may charge you direct, or the supplier may add the broker fee to your energy price. Ask for the total fee in pounds over the whole contract, not only pence per kWh.

Ofgem says suppliers must give details of service fees included in a bill if asked. For micro and small business customers, brokers should also belong to a qualifying dispute settlement scheme. Check the scheme before signing.

Check tax, service, and green claims

Build the budget from the cost before VAT. Include the Climate Change Levy, or CCL, where it applies. Government guidance says CCL normally applies to energy used in agriculture, though small supplies and some uses may be exempt. Ask your accountant or tax adviser to check your own position.

If the offer is called green, ask what that means. Is the electricity backed by certificates? Does the supplier buy power from named renewable sites? Will it report carbon data? A clear claim can support farm buyers and audits. A loose claim may add no useful proof.

How Do You Compare Farm Electricity Quotes Fairly?

Put every quote into one table. Use the same annual kWh, the same contract start date, and the same term. If rates change by time, use your real day and night split. Add every fixed fee and tax that can be known.

Run a simple stress test. Price each quote at 10% more use and 10% less use. Then test a busy month with a higher peak. This shows whether one offer is only cheap under a narrow forecast.

Farm example: A grower chose the lowest unit rate, but missed a high daily charge on three meters. Another offer had a slightly higher unit rate but a lower full-year cost. The total, not the headline, showed the better deal.

When Should a Farm Start the Renewal Process?

Start six to twelve months before the end date. This gives time to clean meter data, gather quotes, ask questions, and choose a good buying day. It also reduces the risk of a rushed phone sale.

Use a short plan:

• Six to twelve months before: Check end dates, meters, and planned farm changes.
• Three to six months before: Gather use data and seek like-for-like quotes.
• One to three months before: Check final terms, fees, tax, and authority.
• After signing: Save the contract and confirm the start date in writing.
• First month of supply: Check the opening read, rates, fees, and VAT treatment.

Markets move, so an early quote is not always the one to take. Ask how long each price is valid. Set a target budget and decide who may approve the deal. This stops a sales call from forcing a quick choice.

Can Solar, Batteries, or Flexible Use Change the Deal?

Yes. On-site power can change how much electricity the farm buys and when it buys it. Tell each supplier about solar panels, a battery, an export meter, a generator, electric heating, or new vehicle chargers. A quote built on old use may be a poor fit.

Solar may cut daytime imports, but the farm may still need much power on dark winter days. A battery may reduce sharp peaks or move buying to cheaper times. Flexible loads, such as some pumps or cooling tasks, may also move away from costly periods. Animal care, food safety, and work safety must always come first.

Ask whether the contract has rules for exported power, private wire use, or major changes in demand. Electricity bought from the grid and electricity sold to it may sit under separate agreements. Do not assume one renewal covers both.

Use measured data before buying costly kit. A simple load study can show whether the best saving comes from making power, storing it, moving demand, or cutting waste. It can also help you choose a contract that works with the project rather than against it.

FAQ

Can I switch a farm electricity supplier before my contract ends?

Usually, no. Most business suppliers do not allow an early switch, and an exit charge may apply. Read the end and exit terms first. You may arrange a future contract before the old one ends, but the start dates must match.

Is a fixed farm electricity price fully fixed?

Not always. The energy unit price may be fixed while network, meter, policy, tax, or other named costs can change. Ask the supplier to list every fixed and variable part in writing before you agree.

What happens if I miss the renewal date?

The supply may move to an out-of-contract or deemed rate, depending on the old terms and events. Such rates can change and may cost more. Contact the supplier at once, ask for the current rate, and seek a suitable contract.

Do farms pay Climate Change Levy on electricity?

Agricultural businesses normally pay CCL on taxable business electricity. Some small supplies and specific uses may qualify for relief or exemption. The rules depend on the use, not just the word “farm”, so seek tax advice for your case.

Should I use an energy broker for my farm renewal?

A broker can help collect quotes and explain terms. Check its experience, supplier panel, total fee, authority, and dispute scheme. Ask for all offers and the full contract in writing. You can also seek quotes direct from suppliers.
