Working on Worcester Bosch boilers every week

Worcester Bosch boilers are the most common appliance in the properties we work in, from Greenstar CDi Classics fitted a decade ago to the current Greenstar 4000 and 8000 ranges. Familiarity matters on a breakdown: knowing the usual failure points on a given range shortens the diagnosis considerably. Serving Stratford-upon-Avon and the surrounding Warwickshire area.

We repair Worcester Bosch boilers, carry out the annual service to Worcester's own benchmark schedule, and install new Greenstar boilers with the manufacturer warranty registered on your behalf.

Worcester's warranty terms require an annual service by a competent engineer to stay valid, and we leave a completed service record every visit so that cover is never in question.

On oil we also cover the Greenstar Heatslave and Danesmoor ranges, which are OFTEC work rather than Gas Safe, and we hold both.

Common signs to look out for

  • Greenstar repairs and fault code diagnosis
  • Annual servicing to Worcester's benchmark schedule
  • New Greenstar installation and registration
  • Common Worcester spares carried on the van
  • Diverter valve, PCB, fan and pump replacement
  • Oil Greenstar Heatslave and Danesmoor work

Servicing and warranty

Keeping your Worcester Bosch warranty valid

Worcester Bosch warranties require an annual service by a registered engineer with the service record completed. Miss a year and the cover can be refused when you most need it.

We follow the manufacturer's own service schedule, test combustion with a calibrated analyser and leave a written record every visit, which is also the paperwork a buyer's surveyor will ask for later.

For landlords we combine the Worcester Bosch service with the CP12 gas safety check on a single visit and email both documents the same day.
