Why this matters in Woking (GU21)
Two things move the price in Woking specifically: flue route (rear-exit vs vertical vs long horizontal) and mains pressure. Woking water is hard, so we build in a scale reducer and magnetic filter as standard — around £120 extra, avoided at your peril. Old-house complications (town-centre flats) can add £150-£400 for pipe upgrades.

Are Worcester Bosch worth the premium in Woking?+
In our view yes, because of the 10-12 year Accredited Installer guarantee — no other brand matches that in the domestic price bracket. Every fault, every part, every hour of labour covered by Worcester Bosch directly for a decade. Better sleep than saving £150 on a lesser brand.
Do you fit boilers other than Worcester Bosch in Woking?+
Yes — Vaillant and Baxi are our other regular fits, typically £150-£300 cheaper on hardware. But you lose the 10-12 year guarantee, and their diagnostics network in GU21 is less mature. Most Woking customers pick Worcester once we walk through it.
Any hidden extras on a Woking boiler install?+
No. The written quote is the price you pay — flue kit, filling loop, magnetic filter, scale reducer, disposal of the old boiler, Building Regulations notice and manufacturer registration are all included. The only variable is if we open up a wall and find something no survey could predict, in which case we quote before proceeding.
