If your friend's floor is floorboards (not concrete) and there is an air
brick on an external wall ventilating the under floor space then she
could
ask if a floor vent can be fitted instead of having a 4 inch diameter
hole
bored through the wall. As far as I am aware the regulations still permit
this.
Nobodies asked so I will, what is this to do with cavity wall insulation?.
Does this replace an existing vent or do they make a new hole?

Sorry, I didn't read this post before I asked.

When we had cw insulation it was never brought up. We don't have open fires
(i.e. solid fulel) but we have gas fires in two rooms and they need air just
the same.

We weren't asked about fires at all.

I have had three estimates for cavity wall and loft insulation recently.
One gave no information, the second was very informative the third a
little info. The informative one checked the fire, said as it was below
X KW output (forgotten the figure) it was ok. He also said that as I had
2 vents, one for a toilet the other in the cloak room when the
installers came they would check that they were sleeved core vents, if
not they will charge £45 to replace them. Also to thoroughly check
where all cables and pipes pass through the walls that both inside and
out are sealed to prevent the insulation escaping. As his price was only
a couple of quid above the cheapest he will get the job.
