Local issues we see ## Common Bicester plumbing & heating problems. Bicester's very fast growth has produced a specific set of new-build and post-warranty issues. ### Post-warranty rebalancing New-build heating systems commissioned to a tight programme often need proper rebalancing 2–3 years in. We fix what wasn't set up correctly first time. ### Unvented cylinder faults Almost every new Bicester home runs an unvented cylinder. Expansion vessel charge loss, PRV weeping and immersion issues need qualified attention. ### Elmsbrook heat pump maintenance The eco-town's heat pump systems need competent servicing, we're that team. ### Missing warranty registration Warranties silently lapse when nobody keeps up annual servicing. We restart the compliance trail. ### Hard water on new fittings Bicester's hard water starts scaling brand-new brassware and cylinders within months. Scale protection is worth fitting early. ### Winter condensate freezes External condensate lines on new-build combis lock out in cold snaps. Simple lagging solves it permanently.
