's a bit of background there. I think I would caution against doing the yourself unless you feel quite sure, but if you do, the FAQ has some useful guides for testing the installation afterwards to prove there are no leaks.
Tap connectors are for taps, for water, not for gas and therefore not an approved fitting for gas and therefore illegal (and reportable under RIDDOR to the HSE who will promptly do .... nothing, probably)
It sounds like you need a proper BSP pipe connector to compression adaptor. These will typically seal on the threads, and you can use the gas version of PTFE to assist in getting a good seal.
Good, this is exactly why I have posted the question, instead of just jumping in here...
The meter has a flexable metal pipe between the outlet and the old iron piping, this has a captive nut on, just like the "tap connector" does, this is why I thought this was the correct fitting.
I have had a better look at the connections, and what Screwfix has to offer, and think I mught have identified the correct fitting nowl...

you confirm my thoughts here?

(Fernox Jointing Compound) the correct thing to apply to the thread to seal it
Just to put your mind at rest, I will be getting a Corgi mate of mine in to check what I propose doing before I actually do anything. I am just trying to learn, and get the bits and pieces ready...
Compression fittings like that are intended for water, and I'm pretty sure that they're not approved for gas.
You need a fitting where the 22mm pipe connection is a *solder* joint rather than compression. The other end (3/4" BSP female thread) is often referred to as "female iron" - even though it's made of brass.
So you need to look for a 22mm solder ring (or capillary) to 3/4 Female Iron elbow - something like BES product 9240. You can find it at
It is perfectly in order to use the compression female iron on gas (so long as it is readily accessible). Saves having to remove and cap gas meter whilst soldering too.
Are you talking about the connection to the outlet side of the gas meter? These are fittings to BS 64 (IIRC). Available from the better plumbers' merchants, also known as 10-light fittings.
Anyway the person who is doing the job will know what to use, what's more the existing meter will have an outlet fitting to 3/4" or 1" BSP whcih can then be converted to 22m with a suitable which is NOT a tap connector.
