Book your annual boiler service

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 ensures 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.

Book your annual boiler service through our online service portal, MyVAILLANT Web.

Vaillant Maintenance and Support Plan

If your boiler is out of guarantee and you have not already taken out a plan, you could take out the maintenance and support plan. Provided by Domestic & General Services Limited, these plans are designed to maintain your boiler and controls, and to keep them working efficiently by providing you with an annual service each year and other benefits as described below.

  • Annual service to help maintain your boiler
  • Exclusive access to our Boiler Care portal
  • Ongoing hints and tips to keep the boiler in good working order
  • Access to our dedicated Contact Centre: 7 days a week, 364 days a year
  • Services & repairs carried out by Gas Safe registered engineers
  • Repairs up to the value of £1,500 if an issue is found during the annual service or your boiler stops working

Through our online support you can access hints and tips and troubleshooting at any time during the term of your plan, in order to help ensure your boiler stays in good working order. You will also receive an annual service and support via telephone or online if your boiler is not working.

If an issue is found during the annual service or your boiler stops working, we can arrange for onsite visits by our own nationwide network of Gas Safe registered boiler engineers, to the value of £1,500. If we are not able to repair your boiler or we decide that it is beyond economic repair, Domestic & General will arrange for your boiler to be replaced with a new one, up to the value of £750.
