What we do

Worcester Bosch boilers in Aberdeen in Aberdeen and Aberdeenshire.

Worcester Bosch is the boiler most Aberdeen households end up with — and for good reason. The Greenstar range has led the UK best-seller list for over a decade, the build quality is genuinely excellent, and when one's fitted properly and serviced annually, you get a 10 to 12 year warranty. We work across the full current range and on older units where parts are still available. Whatever's in your airing cupboard, we've probably seen it.

Brands: Greenstar 4000, 8000 Style, 30Ri, Highflow CDi, Junior 24i, plus Worcester Heatslave oil boilers and older R, RD and Si models where parts can still be sourced.

When to ring us about a Worcester Bosch boiler

  • Worcester showing a fault code — typically F22 (low pressure), EA (flame loss), D5 or E9
  • Diverter valve gone — hot water works fine but no heating, common from year 8 onwards
  • Boiler locking out despite no fault code, or kettling under load
  • Annual service due, especially if you want to keep the Worcester warranty valid
  • Considering replacing an old Greenstar with the newer 8000 Style
  • New install — combi swap, system-to-combi conversion, or first-time fit

Frequently asked

Questions we get asked about worcester bosch boilers in aberdeen.

How long is the Worcester Bosch boiler warranty?
Standard warranties on a new Worcester Greenstar combi run 5 to 7 years, extending to 10 or 12 years when installed by a Worcester Accredited Installer and serviced annually. The 8000 Style currently leads with up to 12 years on the longest tier.
Why is my Worcester boiler showing F22?
F22 means low system pressure. Top up to between 1.0 and 1.5 bar using the filling loop under the boiler, then press the reset button. If the pressure keeps dropping back down, there's a leak somewhere in the system — ring us and we'll find it.
What does a Worcester Bosch boiler service include in Aberdeen?
Visual inspection, gas tightness test, combustion analysis with a proper flue gas analyser, flue and ventilation check, expansion vessel charge, and the Worcester service logbook completed and signed. That's the schedule the manufacturer needs to keep the warranty alive.
How much is a new Worcester Greenstar combi in Aberdeen?
Depends on the model and your existing setup. Ring us with the kW rating you need — or describe your property and we'll size it on the call — and we'll quote everything in writing: boiler, flue, controls, system flush, removal and labour.
Should I replace my Greenstar with the 8000 series?
If your current Greenstar is past year ten and repair costs are mounting, the 8000 Style is a sensible upgrade — better efficiency, smarter controls, longer warranty tier. We'll only recommend it if it actually makes sense for you.
Can you sort an EA flame-loss fault?
Yes. EA usually points at the ignition leads, the flame sense electrode, or — less commonly — the gas valve. We carry the common Worcester parts on the van so most EA faults are same-day fixes.
