We fit 3 Worcester Bosch models — the Greenstar 1000, 4000 and 8000 — from £1,999 fitted with warranties up to 10 years. Every price includes the flue, thermostat, magnetic filter and a system cleanse.
The Worcester Bosch models we fit
- Worcester Greenstar 1000 — £1,999 fitted, 5 year manufacturer warranty. In plain terms: a solid budget choice for a flat or small terrace.
- Worcester Greenstar 4000 — £2,699 fitted, 10 year manufacturer warranty. In plain terms: quieter, with better hot-water performance — worth it in a family home with a power shower.
- Worcester Greenstar 8000 — £2,899 fitted, 10 year manufacturer warranty. In plain terms: quieter, with better hot-water performance — worth it in a family home with a power shower.
Every fitted price includes the flue, wireless thermostat, magnetic filter, system cleanse and inhibitor, with the warranty registered in your name — see the full price page for what is and is not included.
Recent Worcester work
A 17-year-old Greenstar Ri in Solihull with a failed main heat exchanger, replaced like for like with a new Greenstar Ri ErP 18kW in the same kitchen cupboard: new flue, Worcester magnetic filter on the return, system cleaned and dosed, and the 10-year guarantee registered on the day. Job ticket or photos and full write-up.
We also replaced an end-of-life boiler in Sutton Coldfield with a new, energy-efficient Worcester LPG combi, with a 10 year manufacturer warranty registered for the customer — see the full case study.
Warranty terms
Worcester Bosch warranties on the models above run to 10 years, registered by us at handover. One condition applies across every manufacturer: the warranty stands only on a system that was cleaned and dosed at install — which every one of our installations includes as standard.
