What are the different types of domestic heating oil?

In the UK, the main domestic heating oil is kerosene. It’s the most common domestic heating oil and offers an efficient burn for oil-fired boilers. Some older domestic heating systems may use alternative fuels like gas oil, but kerosene oil is by far the most common and recommended for home heating.

What are the regulations for storing heating oil?

In the UK, heating oil storage is regulated to prevent leaks, pollution, and fire risks, especially for tanks over 3,500 litres. These include: 

• Bunded tanks are required if a tank is near a water source (e.g. streams, drains, wells) to prevent pollution in case of a leak.
• Regular inspections should be carried out to check for corrosion or damage.
• Maintain a safe distance (between 600mm and 1.8m) from buildings, boundaries, and potential sources of ignition. 

Can heating oil freeze?

Kerosene heating oil will freeze at around -40°C, so it’s unlikely to freeze in a typical UK winter. However, in very cold weather (-5°C to -10°C), kerosene can thicken and “gel”, which can affect flow and performance.
