How Much A Vaillant Boiler Service Costs

£70-90+vat from small heating companies.

This boiler maintenance price will increase to £85-120+vat for larger companies that employ dozens of engineers.

I’d be suspicious of any heating company offering a boiler service below this cost. As a precaution, before you book a repair always take their Gas Safe registration details and check them here.

What Repairs Are Covered In A Vaillant Boiler Service Plan?

If you’re due an annual service on your Vaillant machine, but you also have a fault with your boiler, don’t expect the engineer to fix it for free.

A boiler service is exactly that, a service.

Advise your engineer of the potential fault in your Vaillant boiler system, and explain that you want a service done after the fault has been fixed.

Extra Support and Products? What’s Included In A Vaillant Boiler Service Plan

Boiler engineers will be ticking things off their service list when they’re at your property.

If you’re a landlord, you’ll need a Gas Safety certificate to be provided after the Vaillant boiler repair service is complete.

This isn’t compulsory for homeowners, but it’s advisable. It gives you some come back if there’s an issue with the repairs or services.

You’ll also be able to assess what’s been done.

For instance, using a flue gas analyser, they’ll check the flue gases are within tolerance.

The details of the boiler tests can be provided via printout using some flue gas analysers. Alternatively, they should be written on the Gas Safety certificate.

If possible, ask your engineer to inspect internal boiler parts of the Vaillant system.

Some boiler parts (such as the heat exchanger) are extremely expensive. If the engineer notices they are blocked with debris, paying them to clean it out could save you 100s of pounds in the long run.

As well as a let-by test (gas leak test), ask them to check your Vaillant boiler’s pressure. If your boiler is losing pressure, the fault needs to be found and fixed.

Finally, if you have a boiler filter fitted, get the engineer to clean it out.

These filters will build up with debris. If they are not emptied, this debris will continue to circulate in the heating system and cause damage.

Remember, confirm exactly what’s included with your Vaillant boiler service with your engineer before going ahead.

Don’t just assume they’ll do all of the above as part of their boiler service package.

Should You Have An Annual Servicing Or Book A One Off Service Maintenance For Your Vaillant Boiler?

Repairing a boiler is expensive. And, most boiler problems can be avoided, by a simple annual service to check that it can be brought back to good working condition.

As we mentioned above, things like cleaning out the heat exchanger, or servicing the boiler filter to stop sludge build up (that could cause a pump to get blocked and a boiler to lockout) an on annual basis is a great value that will save you a tonne of cash in the long run.

My Engineer Says I Need A New Boiler, Are They Ripping Me Off?

Believe it or not, there’s just as much money to be made by being an efficient Vaillant repair engineer, as there is being an installation engineer.

So, don’t jump to conclusions and assume just because a new Vaillant boiler installation has been recommended, it’s not the best route forward.

Each boiler repair, maintenance and installation service plan is different.

But, if your boiler is out of warranty, is over 5-years old, and has a potential repair bill of over £500 or more, it’s worth considering a replacement.

As you know with anything mechanical (such as cars), once one mechanical part fails, others soon follow. To spend £500+ on a repair for a boiler that might only last a couple of years, is a complete waste of money.
