Repair and Care Plan

Repair & Care is a maintenance & support plan for your broken-down boiler, providing a one-off repair (where repairable) and then ongoing maintenance and support for your boiler and controls, to help ensure they continue to work correctly and to minimise the chances of mechanical and electrical breakdown. If you have taken out a Repair & Care plan, you have a no fix no fee promise. If the expert engineer can't fix the initial fault or if the boiler is beyond economic repair, you'll get a full refund of any monies paid up under the plan until that point - no questions asked.

This maintenance & support plan is provided by Domestic & General Services Limited. The plan provides you with maintenance and support services to help keep your boiler properly maintained, supported and in good working order.

£62.45 a month for 6 months totalling £374.70 (inc. VAT) by Direct Debit

Set up your plan and book your initial Repair & Care appointment through our online service portal, MyVAILLANT Web.
