Lagging is cheap until you need three hundred metres of it, and the regs leave no room to skip it. Live prices on foam tube, self-seal lagging, foil-wrapped sections and pipe wrap are compared here across UK suppliers, largest discount first. Wall thickness is what Part L cares about, so check the spec alongside the price, and bulk boxes of standard bores are where the per-metre cost really drops.
