Full Strip-Down and Deep-Clean Service

Labour price from £225

On applicable Worcester models, this can include a fan-pressure test result outside the manufacturer’s permitted limits. The labour price starts from £225 and covers servicing and testing. Model-specific service kits, seals, gaskets and other replacement parts are additional, as the cost of these can vary considerably between Worcester models.

  • Burner assembly removed and inspected
  • Primary heat exchanger and flueways cleaned
  • Condensate trap and pathway inspected and cleaned
  • Electrodes, seals and gaskets inspected

Boiler and Heating-System Health Check

A more detailed written Home Buyer Heating Report can be quoted separately where required.
