Difficult to say. They should be plumbed in using rigid pipework - so that
may or may not need altering. Making a big difference to the time
involved. If it were simply swapping like for like, it only takes a few

A better question perhaps is how much per hour would a qualified fitter
It just that my mother's elderly neighbour could really do with a more
modern hob with a flame failure device (why on earth aren't these compulsory
fittings on new hobs yet??) and I know from my mother's experience that
elderly women get ripped off something rotten on a regular basis. It would
be good to know what a "reasonable" hourly fee might be just to be able to
advise her if she's been taken for a ride or not.
I am not sure if that "should" was meant to be read as "must" but, as
has been discussed here before, the widely held view that hoses were a
no-no for hobs was based on bad drafting in an earlier version of
includes (per John Rumm)
"11.1.3 A gas hob shall be connected to the termination point by means
of rigid pipework or, unless stated otherwise in the manufacturer's
instructions, a flexible connector and self-sealing plug-in device
conforming to BS 669-1."
I know at least one person with a hob connected recently by a registered
fitter that way.
Of course that's not to say rigid isn't better in other (or most) circs.
And the flexible hose needs to conform - eg not come in contact
with a surface over 70 degrees C or be at risk of damage from drawers.
Except that the rule quoted above, quite clearly (to me at least), says
that either is permissible unless the manufacturer stipulates otherwise (ie
*only* rigid or *only* flexible).
Of course this may not have been the intention of the rule but that's what
Hobs don't need flexible connections but I'm sure in some instances it
would make installation easier.
Free standing must have a flexible hose, and must also have a stability
device. That can be a chain or an anti tip bracket. The purpose of the
chain / bracket is to prevent the thing tipping the content of the hob
on you if someone stands / falls on the open door etc. Its kind of
expected that someone pulling the device out will take enough care not
to stress the gas connection in the process.
Not why that rule exists! If a flexible connector is good enough for a
cooker why not for a hob? What is unique to a hob that precludes use of
a flexible connector which is perfectly adequate for a cooker? Indeed,
what makes it allowed or mandated to use a flexible connector for some
hobs but not others? (That is, if the manufacturer's instructions say so.)
