The energy reality for farming

Understanding where the energy goes is the first step to paying less for it. Here is what typical farming usage looks like across the UK.

Typical annual bill
£8k to £40k
Published benchmark estimate
Business types covered

Electricity a year
10,000 to 350,000 kWh

Figures are estimates from published UK benchmarks priced at 25p/kWh electricity, 7p/kWh gas and about £365 a year in standing charges. They are not quotes. See how we estimate.

Energy in farming and agriculture

Farms and rural businesses are among the most energy-hungry SMEs in the UK, and among the worst served. Ventilation fans, milk cooling, grain driers, glasshouse boilers, heated wash bays and yard lighting run to a biological clock, not an office clock, so you cannot shed load when prices spike. Defra's Farm Business Survey confirms 96% of English farms take mains electricity and that specialist pig and poultry, dairy and horticulture holdings carry the highest electricity intensity of any farm type. Most farm supplies also sit on a single owner-operator contract with no procurement team behind it, which is exactly why so many roll straight onto out-of-contract or deemed rates after harvest. Figures on this page are estimates built from published sector benchmarks (AHDB, Teagasc, Defra, CIBSE TM46) and priced at 25p/kWh electricity, 7p/kWh gas and roughly £365 a year standing charges.

Common energy challenges for farming

  • Milk cooling, plate coolers and vacuum pumps drawing power twice a day, 730 milkings a year

  • Livestock house ventilation fans you cannot legally switch off without breaching welfare rules

  • Grain driers and store fans hammering the meter for six solid weeks at harvest

  • Glasshouse boilers, heat mats and heated troughs burning gas through every cold night

Where the energy goes

The kit that dominates the bill, with the annual kWh and cost bands we see in published benchmarks. Knowing this helps us match a tariff to your usage pattern.

EquipmentkWh a yearCost a year (est.)
Glasshouse Heating Boiler (gas)250,000–2,000,000 kWh£17,500–£140,000
Livestock House Ventilation Fans15,000–90,000 kWh£3,750–£22,500

Water Heating & Pressure Washing6,000–30,000 kWh£1,500–£7,500

Energy saving tips for farming

  1. 1

    Read your meter at the start and end of harvest or housing season so you can show a supplier your real load shape instead of letting them price the worst case

  2. 2

    Fit variable speed drives to vacuum pumps and ventilation fans, which typically cut fan energy by 30% to 50% because power falls with the cube of fan speed

  3. 3

    Recover heat from the milk cooling or refrigeration compressor to pre-heat parlour and dairy wash water, the second largest electricity load on most dairies

  4. 4

    Shift pressure washing, feed milling, store cooling and battery charging to off-peak hours if you are on a day/night or half-hourly meter

  5. 5

    Check whether your farm is on a half-hourly supply, because capacity (kVA) charges and DUoS bands are negotiable at renewal and are often set far higher than your actual peak demand

Illustrative example

What switching typically looks like for farming

Dairy farm

Around 150 milking cows with bulk-tank cooling and a parlour

Typical annual bill
£15,000£30,000
Saving at 3050%
£6,750£11,250estimated

Milk cooling, water heating and vacuum pumps run twice a day every day of the year.

Farming energy questions, answered

Often yes, but it depends on your meters. If the farmhouse and the farm buildings share one domestic meter you are on a domestic tariff and cannot take a business contract. If the yard, parlour, grain store or poultry houses have their own MPAN, that supply is a business supply and can be switched to a commercial contract. Send us a bill and we will tell you in a couple of minutes which situation you are in.
