How Much Does a Farm Shop Pay for Energy?

The honest answer: more than most people realise, and often more than they should.

Farm shops are energy-hungry businesses. The refrigeration runs constantly. The deli counter needs heat. The lights are on from before opening to after close. If you're in an older building — a converted barn, a Victorian farm outbuilding — you've probably got draughts, poor insulation, and heating bills that make your eyes water in winter.

What very few farm shop owners know is what they should be paying. Not what they're currently paying — they know that, because they wince at it every time. But whether that figure is actually fair.

This article tries to answer that.

Based on Ofgem's published consumption data for UK small businesses, and typical usage profiles for food retail operations with refrigeration, a farm shop can reasonably expect to pay somewhere in these ranges:

• Electricity: £4,500–£12,000 per year
• Gas (mains): £1,500–£4,500 per year
• LPG or heating oil (off-grid): £3,000–£8,000 per year depending on usage and fuel type

That's a wide range — deliberately so. A small farmgate shop with a couple of chest freezers and basic lighting is a very different operation to a full deli-café with a commercial kitchen, hot counter, walk-in cold rooms and seating for thirty. Size, opening hours, equipment age, and building insulation all move the number significantly.

What this range tells you is where most farm shops sit. If your bills are comfortably inside it, you may be fine. If they're above it — and you haven't actively reviewed your tariff recently — it's worth finding out why.

The national average annual electricity bill for a UK small business is around £2,890, based on Ofgem's typical consumption figures. For gas it's around £950.

Farm shops pay more than those averages. Usually substantially more. Here's why.

Refrigeration is relentless. A single commercial display fridge running 24 hours a day can use 2,000–3,500 kWh per year. A farm shop with a deli counter, a drinks fridge, a dairy section, and chest freezers for meat can easily have ten or more refrigeration units running simultaneously. The electricity meter doesn't stop ticking overnight just because the shop is closed.

You're often in an old building. Energy efficiency standards that apply to new commercial buildings don't help a farm shop in a 200-year-old stone barn. Heat escapes through walls, roofs and windows that no modern building would have. Heating costs in these buildings can be two or three times what an equivalent modern unit would cost.

Many farm shops are off-grid. No mains gas means LPG or heating oil — and both cost more per unit of heat than mains gas. Ofgem's price comparisons don't even cover these fuels, because they're not regulated in the same way. That means rural businesses are flying blind on what's fair.

You're running a hybrid operation. A farm shop isn't just a shop. It might have a kitchen, a café, a preparation area, lighting for display, refrigerated delivery vehicles plugging in overnight. Each adds to a bill that most comparison sites aren't built to benchmark accurately.

Ofgem classifies business energy customers by consumption size, not by sector:

• Microbusiness: up to 15,000 kWh electricity / 10,000 kWh gas per year
• Small business: up to 25,000 kWh electricity / 25,000 kWh gas per year
• Medium business: up to 50,000 kWh electricity / 45,000 kWh gas per year

A farm shop with a deli and café will typically sit in the small-to-medium range for electricity — often above what Ofgem defines as a small business, even if you only have a handful of staff. That matters because the protections and transparency requirements that apply to microbusinesses don't automatically apply to you.

It also means the comparison tools built for generic UK SMEs aren't well calibrated for your usage. They'll give you a number, but it's not a number built for a farm shop's load profile.

Most farm shops that are overpaying on energy got there the same way.

They signed a fixed contract when they first set up — or took over the business. The fixed term ended. They got a renewal letter, glanced at it, and either signed it or did nothing. If they did nothing, they moved onto an out-of-contract (sometimes called a "deemed") rate. Out-of-contract rates are consistently higher — sometimes dramatically so — than what you'd pay on a new fixed deal.

The suppliers know you're busy. A letter in with the bill is easy to miss. The renewal window — usually 30 to 180 days before contract end, depending on your supplier — closes without you acting. And you drift.

Ofgem data shows this pattern is widespread across UK SMEs. It's not unique to farm shops. But farm shops, with their higher usage, feel it more in absolute terms.

If you want to understand why your farm shop energy bill is what it is, these are the variables that matter most:

Unit rate (p/kWh) — the price you pay per unit of electricity or gas. This is the number your tariff negotiation affects directly. Out-of-contract unit rates can be 30–50% higher than contracted rates for the same supplier.

Standing charge — a daily fixed cost regardless of usage. Often overlooked, but on a farm with multiple meters it adds up quickly.

Meter type — half-hourly meters (common on larger commercial supplies) are priced differently from non-half-hourly meters. If you're on the wrong meter type for your usage, you could be paying more than necessary in standing charges.

VAT — businesses pay 20% VAT on energy, not the 5% that applies to domestic customers. You can reclaim this if you're VAT-registered, but the cashflow impact is real.

Climate levies — charges like the Climate Change Levy (CCL) apply to most business energy. Some qualifying businesses can get a reduced rate through a Climate Change Agreement. Worth checking if your farm has an agricultural exemption or partial relief.

Fuel type — if you're on LPG or heating oil, you're outside the main regulated market. Prices vary significantly between suppliers and aren't subject to the same transparency requirements. Benchmarking here is harder, but the potential overpayment is real.

You can't know for certain without a benchmark, but these are indicators:

• You haven't actively reviewed or switched your energy in the last two years
• You got a renewal letter and just signed it without comparing
• Your unit rate is above 28p/kWh for electricity or 8p/kWh for gas (approximate 2026 market averages for small businesses — verify this changes with market conditions)
• You're on a deemed or out-of-contract tariff
• Your bills have crept up year on year without a clear explanation
• You've never had anyone go through your bill line by line

None of these is conclusive on its own. All of them together suggest it's worth checking.

The straightforward version: upload your most recent energy bill to CostShield.

We'll compare your current spend against Ofgem's published SMB benchmarks for businesses of your type and region, and give you a pound figure for the gap. If there's no gap, we'll tell you that. If there is one, you'll know exactly what you're dealing with — and that number becomes your starting point for doing something about it.

It takes two minutes. It's free. No card, no broker, no sales call.

If your farm shop uses off-grid heating, the benchmarking picture is less clear-cut — but the opportunity is often larger. LPG and heating oil prices vary by supplier, contract length, and whether you own your own tank or rent from the supplier (renting locks you in; owning gives you choice).

We cover off-grid fuel benchmarking as part of CostShield's energy check. If you're not sure whether you're getting a fair price on LPG or oil, upload the bill and we'll tell you.
