or should it be raised. if so how much.

I build a hearth flush with the floor and the BCO never batted an eyelid.

I think the size/materials is what matters, not how high it is.

I cannot remember there being any height stipulation, just clearance
distances and provision for combustion air if over 5kW(t).

You'd best check in Part J of the building regulations, they used to
be available as a download on the ODPM site but I think they're in
www.planningportal.gov.uk now.

Making provision for sweeping the flue of a pellet stove normally
dictates the position as space for this tends to be much larger than
the part J requirements.

I can see how height may be relevant, i.e. its easier to push a rug
onto the hearth if it is not raised, etc. The info is in some BS which
was quoted on a fireplace I saw (must be fitted in accordance with BS
xxx) - it can be viewed in the local library. Anyone know the relevant
BS ?

IIRC part J stipulates that there should be some sort of barrier
between the floor and hearth "such as a level change" to discourage
carpets/rugs being lain onto the hearth. I don't think it specifies a
height - and leaves it open to other forms of barrier.

Did they ever sort out the building regs regarding hearths? The text
(below) was taken from the brochure for my fire, I didn't put one in, which
the installer didn't worry about.

HEARTHS
You may have noticed that not all products are shown with floor hearths. A
hearth is a safety feature and is described in the Building
Regulations very clearly for traditional fire types. As with most
technological products, regulations take time to ´catch up¡ with
contemporary developments. There are differing views on whether a hearth is
necessary or not in the raised chamber fireplace situation.
The Building Regulations state that under some circumstances a hearth is
not required, while in the same circumstances the CORGI
regulations state that a hearth is required. So, it is for this reason that
some products are shown with hearths and others are not, giving
you an idea of what your set-up may be like. The ultimate arbiter of
whether a hearth is required in your particular circumstances is your
registered CORGI gas fitter, but for the avoidance of doubt we would
recommend that a hearth is fitted.
There are a number of different hearth options shown, some of which are
bespoke. Regulations exist regarding the minimum dimensions
for each fire, so please consult your retailer if you wish to purchase a
bespoke hearth.
