    And how do I verify that it has actually been serviced and it was not just a safety check being carried out?

    I only know it's a Worcester. Not my boiler.
    And it's not brand new, so there would be some work, cleaning, etc, needed I'm guessing.

    This will depend on model, how old , access to boiler

    few years old, easy access in the kitchen.
    What about how to ensure the servicing was actually carried out and not just a safety check?

    depends on the boiler also the experience of the engineer, whats your problem cost or time taken, cost is a given time taken is dependent on the engineers knowledge and know how. i can service some boilers 1/2 hour but some take longer also whether any service parts are required.

    J am assuming you have some issue with how the engineer carried out the service.There are a lot of variables age/make of boiler,how well it has been previously serviced.Some boilers require consumable parts ,some MI's require more to be done,some are more difficult than others.Worcester are not a favourite of mine.
    It is difficult for a customer to know what has been done although a good engineer having viewed it,might explain if it is a straightforward job or if it has been neglected and requires to quote Masood 'a heart transplant and several hail Marys.'This would cost much more than a basic price.Prices vary,start at £50.Do you feel he did very little in a short time?

    I have no issues (yet). There were 2 of them and they said it would take 20 minutes, though I didn't note how long they actually took.
    20 minutes sounds faster than what I've read it's supposed to take, 30 - 60 min. Two of them sounds like it should be faster but I doubt you can have two people working on a boiler at the same time?
    My concern is that I am unable to actually verify what they've done.

    It's easy to check the work of a bricklayer - wall goes up, a plumber fixes a leak, all dry, boiler install, hot water available, etc.. but boiler servicing? In 20 minutes? And as I said, it's not new.

    OK - 20 minutes is fast, but with easy access it is possible to service a newer model Worcester to manufacturer's spec in that time if you're slick and know the boiler inside out, and - importantly - the boiler is already up to operating temperature.

    It's not always necessary to strip the boiler down..

    It depends what some regard as a service.
    There are, on certain models things that must be carried out and things that should be carried out.
    A calibrated flue gas analyser with the right guy operating it. will say in a few seconds weather a full strip down is required. Or other issues. As will a gas rate.
    But in my Veiw a service is not just a check, it's doing the right work on an appliance, so that with best intentions, it should operate safely, efficiently and reliably for the next 12 months. Too many, just stick the probe in the flue and say it's fine.

    I would expect it to take at least 45 min including gas tightness testing etc. It does depend a lot on what they call a service.

    You can't tell if they've done it, just like you cant tell if your car has been fully serviced unless you know what you're looking for.

    Did you employ Gas Safe Registered Engineers?
  16. A1P

    A1P GSR

    In boiler servicing ,as in car servicing,there is an element of trust.You often cannot see anything obvious for your 'hard earned.'As regards 20 mins and 2 men,possibly a bit light on time,Worcester's can take longer than some.As for 2 men ,possibly engineer plus apprentice.In the end try to use a tradesman you trust on a regular basis.When I fit a boiler I do it in the hope the customer will use me to service it according to MI instructions on a regular basis.Good for both parties.

    That's what I was getting at and not being a gas engineer, I can't tell much. There should be a form/report (perhaps there is), stating what has been done and values noted down. I believe an electrical safety check has such a certificate/report.
  18. kasser

    kasser Member

    Yes, engineer is gas safe registered. I don't think I got a receipt for the payment.
  19. kasser

    kasser Member

    By the way, being gas safe registered doesn't mean he will do the job properly?
    As long as he leaves the boiler in a safe condition, Gas Safe won't be on his back. So servicing could mean sticking a probe in there and that's it, even for a Gas Safe engineer...?

    I always print off a FGA ticket but to be honest with you, it means nothing to most customers so I keep them myself on file for twelve month just in case I need to reference it for anything.
    ( I have never had to though).
    I also fill in the service sheet at the rear of the installation manual with comments and CO2/CO Ratio and a few of the other readings. Again, that is more use to any future engineers or myself than the customer.

    You're quite correct. Just because he/she is registered doesn't mean they are thorough.
    What can you do?

    Use a recommended engineer, If you want a full strip down service on your boiler, ( even though you may not need it), you can always ask but it will cost more in time and materials.

    20 mins will be a check

    We allow 45-60 mins

    Tightness test gas system
    Visual check of gas line and meter
    Boiler flue check
    Check system pressure and top up
    Cover off and clean inside (Hoover etc)
    Check expansion pressure
    Clean trap
    Check probes
    Fga boiler max and min rate
    Gas rate appliance
    Cover back on
    Fill out paper work and email to client

    I've cropped out the address but you get the idea


    Good luck doing that any faster

    £50. How much is is supposed to cost approximately?
  26. jtsplumbing

    jtsplumbing Plumber GSR

    £50. is about average depending where you are, Time wise I average around about 1hr, depending what is required, always run system as well to make sure everything is working, vent rads top up if required, Did you use a national Co or independent engineer ?
  27. gas2016

    gas2016 GSR

    The problem is a lot of the bigger companies as well as independent guys are doing a safety check rather than a service and the ordinary joe blogg is non the wiser normally. 20 mins for a service is some going even if there's no strip down
  28. jtsplumbing

    jtsplumbing Plumber GSR

    The main problem with type of job (Service) is the cost ! customer always puts the cost first, that is the reason a full service as outlined in the manufactures instructions rarely gets done as it would more than double the cost if carried out to the letter, and I think that most people would not be happy paying over £100 every year for a service, landlords being the least likely to have it done, doing a basic check to see if everything is working and safe is better than nothing at all.

    It would help if there was more transparency as well. Passing a safety check as servicing is downright fraud.

    Do you do it as per manufactures instructions ? to be honest I don't know meny people that do BG included , If fact the time they allow their engineers to do a "Service" is Proberly less than the average independent guy takes, all boils down to time & cost
  32. kasser

    kasser Member

    Better yet, don't bother with the servicing.
    Well, it may not be better.

    Maybe there are some people who wouldn't mind paying more if it's clear what they get in return? Seeing the engineer working for a full hour, boiler stripped down to parts, full report with readings in the end, certificates...

    How come electricians manage to do it?

  34. jtsplumbing

    jtsplumbing Plumber GSR

    It would take a lot longer than 1hr to fully strip check all parts and reassemble a boiler + the added cost of replacing all the seals & gaskets.

    Electricians only plug in a test machine and take readings they do-not strip down every plug/socket

    Condensing Worcester boilers require Air/Gas ratios to be checked. in service mode. Both at High/Low levels. The fan pressure has to be checked to make sure the heat exchanger is clean. If the readings aren't found to be within the manufacturers required tolerances, then the heat exchanger will have to be cleaned. This would mean the seal connecting to the primary heat exchanger will have to be replaced. etc. Non condensing boilers are easier to service.

    anywhere between 30m and 2 hours, depends what needs doing it could be £10 for the work and £40 to know what needs doing!
    with a combi, you dont touch what dosnt need attention it just needs to be checked that its good.
    i shine a high powered torch into the condense traps and it s like an x-ray. if its clear then i save 10mins fiddling it on and off...

    Not just that but they write down measurement readings and what they found and give that to you the client.
  41. kasser

    well, that's why I said it may not be a good idea.
    I don't bother with the dentist myself...

    But to stick to the analogy, MOT would be the gas safety check and car servicing would be the boiler servicing, so stick with the MOT so all is safe and think skip the servicing if all you're going to get is the MOT again.
