Estimated cost of works

The estimated cost of work used to determine the charges above should be a reasonable estimate that would be charged by a professional builder to carry out such work (including VAT).
 

Competent Persons Schemes

If a certified installer is not subsequently employed or Competent Person's Certification is not received, the charge in code D19 will be required for each unit. This is to enable checks and tests on the work to be made by our nominated contractor to establish that the work meets with the requirements of the Building Regulations 2010.
