Underfloor Heating That Just Works
Underfloor heating gives you warmth where you actually feel it — under your feet — while freeing up wall space, removing radiators from view and quietly running at lower temperatures than a traditional system.
Based in Porthmadog, Lloyds Plumbing & Heating installs wet underfloor heating systems for homeowners, builders and renovators across the Llyn Peninsula and wider Gwynedd area.
Whether it's a single kitchen extension, a full ground floor, or a complete new build, every system is designed to suit the property and installed to a standard built to last.
Where underfloor heating works best
We install underfloor heating across a range of property types and project stages.
New build homes

Conservatories and garden rooms
Self-build projects

More Comfort, Lower Running Costs
Because underfloor heating spreads warmth evenly across a whole room from the floor up, it runs at much lower water temperatures than a radiator system — which means less work for your boiler and lower running costs over time.
It also pairs brilliantly with modern A-rated boilers and heat pumps, making it one of the most efficient ways to heat a home now and for years to come.
We handle everything from initial system design and pipework layout through to manifold installation, screed considerations and final commissioning — leaving you with a system that's ready to be tiled, screeded or covered when you are.
