Some companies offer insurance backed guarantees but all this indicates is an annual insurance by the guarantee company, with the insurance in the name of that company not the property treated, and if it is not paid annually then it collapses.

When comparing the guarantees other companies offer, check if they can offer what we can:

  • Independently checked for Technical Competence
  • Health & Safety competence and Financial Stability
  • Underwriter authorized and regulated by the FSA
  • Access to the Financial Ombudsman Service
  • Insurance certificates for EACH property
  • Security of the Financial Services Compensation Scheme
  • NHBC & Zurich Approved
  • Insurance Premium Tax (IPT) applied (as required by law for all genuine insurance)
  • Automatic FREE assignment on sale of property
  • Protection against contractor failure for ANY reason

As you can see from the above, we take very seriously the matter of guarantees for the services we provide, thus we are confident that we present you with the best insurance possible.
