If you have a gas meter, your boiler uses gas.
Your system uses oil, stored in a tank in the loft or outside the house. Having an oil boiler usually means you're not connected to mains gas.
If your system uses electricity, you won't have a gas meter. You're likely to have an electric boiler if you use underfloor heating.
Combi boilers heat water directly from the mains when you turn on a tap. So you get hot water instantly – without a cylinder or a tank in the loft.
If you have a hot water storage cylinder as well as a cold water tank in the loft, your boiler is likely to be Standard. These are also called Regular, Traditional or Conventional boilers.
If you have a hot water storage cylinder but no cold water tank in the loft, you're likely to have a System boiler. The boiler will normally have a pressure gauge on the front of it.
The house stands on its own, and isn't attached to any other buildings.
Your house is one of a pair that share a single common wall.
Your house is one of a row. You've got walls on either side shared with neighbours' houses.
You're in an apartment block, or part of a larger house.
You have a detached house that is all or mostly on the ground floor.
If your hot water is fed from through a cold water tank, then you likely have a vented water cylinder.
If your hot water is fed directly from the cold water mains, then you likely have an unvented water cylinder.
