Boiler Service by Vaillant

Why book a Vaillant annual boiler service?

By booking with Vaillant, you will benefit from a rigorous 12 point check on your boiler by an expert, in-house factory trained engineer - who better to look after your boiler than the people who made it?


Having your boiler serviced once a year by a Gas Safe registered engineer ensure that you

  • maintain your guarantee after the first year.
  • avoid future repairs when problems are spotted early.
  • save energy as our engineer will check your boiler is running efficiently.
  • increase its life expectancy.
Most importantly an annual service ensures that your boiler is safe.
Make sure you arrange for regular servicing as carbon monoxide leaks may be fatal.

To maximise performance and reliability, it's important to keep your boiler and heating system well maintained. You can book online with us for as little as £85.

Need to know

Vaillant Maintenance Plans are only suitable for domestic boilers under 8-years-old that are in good working order and out of guarantee. Your boiler also shouldn’t be protected by a similar product.

The plan excludes the cost of repairs for scale and sludge, malicious and cosmetic damage, indirect costs, and problems related to the initial installation.

We’ll remind you when an annual service is due to book your Vaillant engineer visit.
