⚠ Why Wokingham heating advice is different
The guides on this blog are written with Wokingham and Berkshire conditions in mind. Generic heating advice from national websites often doesn’t account for the specific factors that affect homes in RG40, RG41 and the surrounding area:

Hard water (330–380 mg/L CaCO₃): Wokingham sits on a chalk aquifer producing some of the hardest domestic water in England. This accelerates limescale build-up on boiler heat exchangers, electric shower elements, fill valves and thermostatic cartridges far faster than the national average — affecting servicing frequency and repair decisions.

1970s–90s housing stock: A large proportion of Wokingham’s residential properties are from the post-war and New Town expansion eras, with boiler systems now 25–40 years old and approaching or past economic repair. Repair vs. replacement decisions specific to this housing stock are covered in the guides below.

Prevalent boiler brands: Vaillant and Worcester Bosch dominate in newer builds; Baxi, Potterton and older Worcester models are common in the 1970s–90s stock. Stuart’s guides reflect real fault patterns from the brands actually found across RG40.
