ECO Affordable Warmth Scheme and Carbon Saving Obligation

The ECO is a grant scheme running along the government’s Green Deal loan scheme, which was launched at the end of January 2013. Again, it is funded by UK energy suppliers.

HHCRO (Formerly the Affordable Warmth scheme)

This scheme funds cavity wall and loft insulation for anyone receiving certain benefits. You can check your eligibility and apply by visiting our HHCRO Free Insulation page. 

Carbon Saving Obligation

This scheme gives grants to either partially fund or give free solid wall insulation installations, and is open to everyone as it is not means tested. It is not yet clear how people will be able to apply to the scheme – we should know more in May.

FAQs

Does cavity wall insulation cause damp?
No, as the cavity insulation is generally water repelling, meaning water cannot cross from the external wall to the internal wall via the insulation - the only way it could cross is if another obstruction is connecting the walls. Before installing the insulation, the empty wall cavities are inspected for obstructions with a special tool called a boroscope. Any obstructions are noted and cleared by the installers before the insulation is injected.
How long does it take professionals to install loft insulation?
It takes professional installers about 2 hours to install loft insulation in an average sized loft.
Why wasn't my house built with cavity wall insulation and the right amount of loft insulation?
Houses comply with the building regulations that apply at the time the property is built. Since the oil crisis in the early 1970s, the insulation standards in the Building Regulations have been progressively upgraded.
Do I need to provide extra ventilation to my loft space if I insulate it?
That depends on whether it is adequately ventilated at the moment. Increasing the amount of insulation in the loft can lead to condensation of water vapour on any timber there. If your loft is not properly ventilated your installer will advise you, and can install simple vents that will ensure an adequate air flow through the loft.
