Oil heating in Norfolk: kerosene costs, tank rules and what to check

Where Norfolk heats with oil

The Census asked every household how it heats its home. In Norfolk, 56.8% used mains gas alone, against 74.0% across England, and 17.3% used oil alone, against 3.2%. The split follows the gas network, which covers Norwich and the towns far better than the villages. Only 0.2% of households in the Norwich council area heat with oil alone. In King’s Lynn and West Norfolk the figure is 25.1%, in North Norfolk 24.6%, in South Norfolk 24.2% and in Breckland 23.7%.

Ward figures show the pattern more sharply. In the Norwich suburbs more than 80% of homes are on mains gas only: 85.1% in Sprowston Central (Sprowston), 84.0% in Hellesdon South East (Hellesdon), 79.9% in New Costessey (Costessey), 82.4% in Thorpe St Andrew North West (Thorpe St Andrew) and 84.9% in Taverham South (Taverham). The market towns are much the same: 74.0% in Central Wymondham, 72.7% in Attleborough Queens and Besthorpe (Attleborough), 76.1% in Dereham Withburga (Dereham), 83.0% in Thetford Boudica (Thetford), 78.5% in North Lynn (King’s Lynn) and 82.2% in Yarmouth North (Great Yarmouth).

The coast is mixed. Hunstanton (69.1% gas only, 3.0% oil only), Cromer Town (Cromer, 67.9% and 3.3%) and Wells with Holkham (Wells, 64.8% and 8.9%) are mostly on gas. Burnham Market and Docking ward (Burnham Market) is the reverse: 7.6% gas only and 47.6% oil only. The highest oil figures in the county are in rural wards such as Ormesby in Great Yarmouth borough (55.9%) and Priory in North Norfolk (54.6%).

A ward figure is an average, so check the house itself. No gas meter, no gas regulator box on the outside wall and no gas hob usually means oil, or occasionally bottled or tank LPG.

What kerosene costs

BoilerJuice checks the lowest price for a 1,000-litre kerosene order in every postcode district each day and publishes the average. On 24 September 2026 it was 117.14p a litre including 5% VAT. Nottingham Energy Partnership, which has tracked domestic fuel costs monthly since 2007, recorded 97.02p a litre for September 2026. The gap between the two figures, a few weeks apart, shows how quickly the price is moving. The Bank of England’s September statement said the conflict in the Middle East had pushed up crude and refined energy prices since its previous meeting.

Price per litre also depends on the order. BoilerJuice’s average is for 1,000 litres; smaller orders usually cost more per litre. Check BoilerJuice or Cheapest Oil before you ring a supplier, and quote the price you have seen.

Group buying is the other lever. ThinkingFuel, run by the charity Community Action Norfolk, is free to join: members order on any working day at a negotiated price, the supplier is Affinity Fuels, and the charity advertises a saving of £120 a year. Some parish councils and village groups also run their own group orders; the parish clerk will know.

How much a house burns

Nottingham Energy Partnership bases its comparisons on a medium-sized home that needs about 12,500 kWh of heat a year. A litre of kerosene holds 9.78 kWh on its figures, so with a 90% efficient boiler that home burns about 1,420 litres a year. An older farmhouse with solid walls will burn more; a small modern house less. The best guide to a particular house is the seller’s delivery receipts for the last two or three winters, so ask for them.

Oil now costs more than gas for the same heat. On Nottingham Energy Partnership’s September 2026 figures, a kWh of heat cost 11.02p from kerosene and 7.86p from mains gas. At BoilerJuice’s 24 September price the kerosene figure rises to about 13.31p.

Tank rules for buyers

The rules for domestic oil tanks in England are in Approved Document J of the Building Regulations. OFTEC, the trade body for oil-heating technicians, publishes the technical standards installers work to. The parts a buyer needs are these.

• A tank needs secondary containment, meaning a bunded tank or a bund around it, if it holds more than 2,500 litres, or sits within 10 metres of a river, stream, lake or coastal water, or within 50 metres of a well, borehole or spring, or where a spill could run into an open drain. The guidance counts ditches and field drains that feed watercourses as inland freshwaters, which catches a lot of rural Norfolk.
• A tank less than 1.8 metres from any part of a building needs fire protection: a fire-rated wall or eaves, or a fire wall between tank and house.
• A tank less than 760mm from a boundary needs a fire wall or a fire-resistant boundary wall.
• Installing a new tank or boiler is notifiable building work. An installer registered with a competent person scheme such as OFTEC’s can certify it and should give you an OFTEC CD/10 installation completion report. Without that, the work should have gone through building control. On a recent-looking tank, ask the seller for one or the other.
• A tank on a listed property may need listed building consent. Inside the Norfolk Coast National Landscape, the Broads or a conservation area, expect closer scrutiny of a new tank in view of the road. Ask the planning authority (North Norfolk District Council, the Borough Council of King’s Lynn and West Norfolk or the Broads Authority) before you set a survey timetable.

A tank that fails these tests is a cost to negotiate on. Checkatrade’s September 2026 cost guide puts a replacement at £1,500 to £4,000, with most homeowners paying around £2,500 for supply, removal of the old tank and installation.

Servicing and certificates

An oil boiler should be serviced once a year. The engineer records the combustion readings and settings on an OFTEC CD/11 servicing and commissioning report, and a run of those reports is the service history a buyer should ask to see. Check your boiler warranty and home insurance policy for servicing conditions.

Gas engineers must by law be on the Gas Safe Register. There is no equivalent legal requirement for oil engineers. OFTEC registration matters for installations, because a registered installer can certify the work without a separate building control application. OFTEC’s find-a-technician search covers the whole county.

What to check at viewing and survey

• A tank under trees. Leaf litter holds moisture against the tank.
• A single-skin steel tank on concrete blocks, common on older properties and usually not bunded. Price a replacement.
• A tank close to the house, a shed, the fence or a ditch with no fire wall or bund. The distances that matter are in the tank rules above.
• No CD/10 for a tank or boiler that looks recent, and no CD/11 service records.
• A buried oil supply pipe without a protective sleeve. Ask where the line runs.

Replacing oil

With the £9,000 grant, a heat pump at the median installed cost leaves about £3,900 to pay, close to the cost of a new oil boiler. Running costs are close too: at September’s prices, heat from an air source heat pump cost 10.54p a kWh against 11.02p from kerosene. That figure assumes the heat pump delivers 2.94 units of heat for each unit of electricity. A draughty solid-walled cottage may not reach that, so get the insulation and heat-loss survey done before you commit. By June 2026 the scheme had paid for 2,357 heat pumps across Norfolk’s seven districts.

The rest of moving off-grid

Dates to watch

The £9,000 Boiler Upgrade Scheme rate for off-gas-grid homes runs until 31 March 2027. After that the grant returns to £7,500 unless the government extends it.

HVO (hydrotreated vegetable oil), a renewable liquid fuel, can replace kerosene in many existing oil boilers after modification. It is not yet sold widely to households, and it pays more fuel duty than kerosene when used for heating. The government consulted on renewable liquid heating fuels at the end of 2025, and OFTEC is pressing for the duty to be cut. Until that is decided, HVO is not a practical choice for most Norfolk homes.

How we produced this guide

Heating figures are from the 2021 Census, table TS046, for Norfolk, its districts and 2022 wards. Kerosene prices are BoilerJuice’s published UK average for 24 September 2026 and Nottingham Energy Partnership’s September 2026 energy cost comparison, which is also the source of the kWh per litre, efficiency and heat cost figures and the medium-home heat demand. Annual costs in the table are those prices multiplied by the litres shown. Tank rules are from Approved Document J (2010 edition incorporating 2010, 2013 and 2022 amendments). Grant levels are from Ofgem; installed costs and uptake from the Department for Energy Security and Net Zero’s Boiler Upgrade Scheme statistics published on 24 September 2026; tank and oil boiler costs from Checkatrade’s September 2026 cost guide.
