Yes. New boilers carry the manufacturer's warranty — up to 10 years on some Worcester Bosch, Vaillant, and Ideal models, provided the system is properly cleaned, a magnetic filter is fitted, and the boiler is annually serviced (we handle the reminders). New radiators and valves carry their own manufacturer warranties. The workmanship on our installs is covered for 12 months as standard. If anything isn't right after we've left, you're calling the same local engineer who did the job — not a national warranty line.
