Regulations regarding Hot/Cold Pipe Insulation in Homes?

[Sputnik0003]

Can some one spell out the Building and Water Supply (and any other) Regulations regarding Hot & Cold Pipe Insulation in domestic properties.

In summary from my reading, all primary heating circuits and water pipes in unheated spaces must be adequately lagged to prevent them from frost.

So, does that mean that running (small bore) heating pipes behind the plasterboard or in the wall cavity require specific lagging?

Similarly, water pipes in outbuildings: I guess there is not a lot you can do to prevent freezing, but is a good preventative measure to fit a drain down valve and instructions to use it to prevent potential bursts (if the building is designed for ocassional use)?

Grateful for your insight.

Whats the point, the regs like all the others will just get ignored as always, Wickes good idea leaflet, "how to" blah blah blah, so then Mr DIY does half a job, then you buy the property with all it's glory of broken gas water electric regs, and ooooooooh, nobody cares.

If you have some pipes that need lagging just do it, regs wont mean diddly.....

So many cowboys around like you who think they know better.

To the OP, one would not normally consider behind plasterboard to be an unheated space because such an area is within the heat envelope of the building (i.e. on the hot side of any interior-exterior insulation).

Cavities on the other hand are a different story and you should seriously consider whether or not you want to run pipes in there. If you are just referring to doing it as a means to getting the pipes through a wall (given your mention of an outbuilding) then that's a different matter. In such circumstances you should consider the risk of freezing but it's outside of the cavity that would require most consideration.

Regardless of any cynicism about the perceived compiance with regs if nothing else they should be considered as something generally approaching best practice hence worthy of being followed.
