Cavity wall insulation

Do you offer cavity wall insulation? I have just found that the house I moved into in 2 years ago and which was built in 2003 has no cavity wall insulation. Thank you.

@DianaMXhambers This isnt something we currently offer I would recommend finding someone approved by one of the three bodies below
The National Insulation Association (NIA)
The Cavity Insulation Guarantee Agency (CIGA)
The British Board of Agrément (BBA).

Also before going ahead with this Under the Energy Company Obligation, some households might be eligible for discounted or free insulation. The eligibility criteria is complex, though. Call the Energy Saving Advice Service on 0300 123 1234 to see if you could be eligible.
