 British Gas installs in mainland Great Britain only. Free installations are through the Energy Companies Obligation and are subject to assessment, technical survey and eligibility criteria. The funding available is to cover insulation and if needed extra specialist equipment i.e. scaffolding and vents. Some properties require more specialist equipment which can't always be covered so if you need more you have the option to pay the extra. Tenants must seek landlord's permission.
 Phone lines are open 8am–8pm Monday to Friday and 8am–4pm on Saturday. Closed on Bank Holidays. Calls are free from a BT landline, however charges from mobile phones and other networks may vary. Calls may be monitored and/or recorded for quality assurance and compliance purposes.

Why free means free
As part of ECO (Energy Companies Obligation) we're working with the government to make millions of homes across the UK more comfortable and cheaper to run with free roof and cavity wall insulation.
Not having insulation is like leaving your roof wide open
