Frequently asked questions
+What's the biggest cost lever in Swansea?
Route choice — merchant to surplus alone typically saves 30–50% on UFH.
+Do I need a UFH designer?
For a whole-house wet system, yes. For a single room retrofit, a manufacturer's DIY pack is fine.
+Is the cheapest route always right?
No — heritage jobs, warranty-critical spec and public projects each shift the calculus.
