If you install at least 1 primary measure, your voucher can be used to help cover the cost of any of the following secondary measures. The amount you get towards the cost of secondary measures cannot exceed the amount you get for primary measures.
Windows: Double/triple glazing (where replacing single glazing), secondary glazing (in addition to single glazing),
External doors: upgrading to energy efficient doors (where replacing single glazed or solid doors installed prior to 2002)
Heating controls and insulation:appliance thermostats, hot water tank thermostats, hot water tank insulation, smart heating controls, zone controls, delayed start thermostat, thermostatic radiator valves.
External doors and every opening window in your home has a gap round the edge that should seal tight when the door or window is fully closed. If the seal isn’t good enough, then cold air can blow in through the gap, and warm air can blow out. Old or badly fitted windows can have gaps around the frame or glass even if they do not open, and doors can have extra gaps around a letter box, cat flap or keyhole.
Single glazed windows lose a lot of heat to the outside air because the single pane of glass is not a good insulator. If you fit double glazed windows instead, then the air gap between the two panes of glass will insulate your window. This will stop heat escaping so quickly and make your room warmer.
The GHG Scheme does NOT replace or repair double glazed windows.
Secondary glazing cuts heat loss by creating a layer of trapped air. This is different to draught-proofing which stops air blowing through the gaps around the edge of the window. To get the most benefit from secondary glazing, you should draught-proof the existing window first. This way, the trapped air really will be trapped.
This method is ideal for listed property as it is removable and does not affect look and style of the existing listed window.
Energy efficient replacement doors (replacing single glazed or solid doors installed before 2020)
The GHG Scheme does NOT cover double glazed doors or old uPVC doors.
