Is a member of your household in receipt of benefits?

This information is only used to see if you may qualify for a grant.

The benefits that we are asking about here include: income support, housing benefit, council tax benefit, working/child tax credit (with an income of less than £15,050), pension credit, disability living allowance, attendance allowance, war disablement pension and industrial injuries disablement benefit.

Built form

These categories apply to houses or bungalows. The description 'enclosed' is typically applicable for 'back-to-back' terraces. For example, an enclosed mid-terrace has an external wall on one side only (the front).

Property age

The standard to which houses are built has changed over time, with recent building regulations specifying progressively higher energy efficiency performance. Answering this question as accurately as possible will help us to estimate some of the energy efficiency characteristics of your home. If you do not know precisely, simply give as close a date range as you can. These pictures of houses built on different dates may help you do this.

Total number of rooms (including house and extension if present, including hall stairs and landing as 1 room)

This helps us to estimate the size of your home, and answering this question as accurately as possible will help us to estimate its energy consumption.

Include any extensions to your home, and consider the hall, stairs and landing as one room. If you have an 'open plan' area in your home, include the number of rooms that you think there would be, if the design were not open plan.

How many storeys?

This is the total number of storeys that you personally inhabit in the property, and does not necessarily include the number of storeys in the whole building, for example if you live in a flat. Please include heated basements or loft conversions, but only if they have a fixed stairway.

Number of exposed sides

The total number of outside walls of your home.

Main wall type

A solid brick wall can usually be identified by the brick pattern, unless the wall has been covered (e.g with plaster). Other types of wall may have been made known to you when you moved in.

If you are unsure whether or not your cavity wall has been filled, you can look for the tell-tale drill hole pattern in the walls where the installer will have filled the cavity. They will normally be drilled through the mortar between the bricks at regular intervals.

Cavity wall: Bricks all same length

Solid wall: Bricks appear short then long

Main roof insulation

If you are not sure about this, you can estimate the thickness using a slim ruler or pencil to test the depth of the insulation – it may irritate your skin, so don't use your bare hand to test the depth. If you feel unsure about how safe you feel on a ladder, simply make your best estimate without investigating your loft.

If you can see the wooden joists in your loft, you probably have less than 100mm of insulation.

Are the single glazed windows draught-stripped?

Badly fitting windows are sources of heat loss. Draught-stripping is the process of filling in these gaps to reduce this. The following images give some examples of typical draught-stripping materials.

Number of open chimneys

Having an open fireplace/chimney will affect how heat is lost from your home. If your home has a chimney and hearth capable of supporting an open fire then it should be included, even if there is no appliance or grate installed.

How many lights have low energy light bulbs installed?

Low energy lights include CFLs and fluorescent tubes If you are not sure if you have these types of bulb in your home, these pictures may help you decide:

Is solar water heating present?

Solar water heating, sometimes referred to as solar thermal heating, uses the sun to provide hot water for homes. A typical installation of solar water heating would involve a roof-mounted panel.

Main heating

What are the different types of heating systems?
Boiler: Central heating systems based on boilers and heat emitters (usually radiators).
Storage Heaters: A storage heater contains heat-retaining blocks that are heated up overnight using off-peak electricity.
Room heaters: Unlike central heating systems, each room is heated individually from its own heating source.
Warm air: The heat is piped around the home using ductwork; individual grilles usually have sliding ‘dampeners’ which open and close to help balance the heat distribution.

Main heating fuel

A very important factor influencing running costs and CO2 emissions is the fuel type used. Answer here about the main fuel used to heat your home; later questions will ask about any other heating fuel you may use.

When was boiler installed?

Telling us when your boiler was installed will give us a good indication of how efficient it is.

What type of boiler is it?

Combination: a boiler that heats your home as well as providing instant hot water (there will be no hot water tank).
Condensing combination: as above but a condensing boiler (more efficient than a standard combination boiler).
Normal (with hot water tank): heats your home and provides hot water which is stored in a hot water tank.
Condensing (with hot water tank): as above, but a more efficient condensing model.
Back boiler: a boiler behind a gas or solid fuel fire which supplies heat to radiators.

What are the main heating controls?

What are the different types of heating controls?

Room thermostat: Turns your heating on or off, depending on the air temperature. If you have one, it is often found in the hallway or living room.
Programmer: Allows you to set the periods when heating and hot water are required.
Thermostatic radiator valves: These can be found fitted on to individual radiators, allowing you to further adjust the temperature in the room.

What is your secondary heating fuel?

Secondary heating means heaters that you use in addition to your main heating system. Please provide information on the type of secondary heating that you use and the type of fuel that is used (if you do not have any other heating apart from your main system, please cross ‘none present’ for these questions).

What type of secondary room heaters are there?

Secondary heating means heaters that you use in addition to your main heating system. Please provide information on the type of secondary heating that you use and the type of fuel that is used (if you do not have any other heating apart from your main system, please cross ‘none present’ for these questions).

Is there a hot water cylinder?

Is there a thermostat on the water cylinder?

A water cylinder thermostat is a sensor that switches off the boiler when your hot water has reached the required temperature.
