How Much Is a Vaillant Boiler Service?

You can expect to pay £100+ VAT to service a Vaillant, when using small, local heating companies.Vaillant boiler service

This maintenance price will increase to £85-120+vat for larger companies that employ dozens of Gas Safe registered engineers. I’d be suspicious of any heating company offering a boiler service below this cost.

As a precaution, before you book an appointment, always ask the Gas Safe registered engineer for their ID card and details, and validate them here.

What Repairs Are Covered In a Boiler Service Plan?

If you’re due for annual service on your Vaillant, which also happens to be faulty, don’t expect the engineer to fix it for free.

A boiler service is exactly that — a service.

So, if you require boiler repairs, advise your heating engineer ahead of time and they may give your Vaillant a fixed price repair quote. After the repairs, they can service the boiler as usual.

What’s Included In a Boiler Service Plan

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

If you’re a landlord, you’ll need a Gas Safety certificate to be provided after the repair service is complete. Getting this certificate isn’t compulsory for homeowners, but it’s advisable: the certificate gives you some come-back if there’s an issue with the repairs or boiler services.

You’ll also be able to assess what the heating engineer has 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.

What to Ask Your Engineer During Service

While you’re getting your boiler serviced, ask your engineer to inspect the internal boiler parts. Some boiler parts 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 boiler pressure. If your boiler is losing pressure, the fault (typically a leak in the central heating system) needs to be found and fixed.

Finally, if you have a boiler filter fitted, get the engineer to clean it out. These filters accumulate debris, and if they’re not emptied, this debris will circulate the pipes and radiators, causing damage and making your boiler less efficient.

And remember to confirm what exactly is included in your Vaillant 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.

One-Off vs. Annual Service for Your Boiler

Repairing a boiler is expensive. Luckily, you can avoid most boiler problems by getting your boiler serviced annually and finding defects early, before they deteriorate.

As we mentioned above, cleaning out the heat exchanger or servicing the boiler filter to stop sludge build annually will save you a tonne of cash in the long run on boiler reparis and heating bills.

So, in our opinion, it’s always best to opt for an annual servicing plan.

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

Believe it or not, a good Vaillant engineer can make just as much money on service and repairs as a boiler installer. So, don’t assume that your service engineer is trying to rip you off by recommending a new boiler instead of repairs.

As a rule of thumb, if your boiler is out of warranty, over 5-years old, and has a potential repair bill of over £500 or more, it’s worth considering a replacement. Like with any mechanical appliance, once one part fails, others soon follow. To spend £500+ to repair a boiler that might only last a couple of years is a complete waste of money.
