Underfloor heating

Underfloor heating installation

We install new wet and electric underfloor heating for homeowners, builders and the trade, from a single room to a whole house. Here is how we work and what to think about.

Three ways to fit a wet system

In screed, overlay and between joists

These are the three main installation methods for wet underfloor heating. We do not always recommend the same one, because the right method depends on the property, the floor construction and the project. Electric systems have their own page.

In screed

The pipework is installed before screed or concrete is laid over the system.

Suits
New builds, extensions and floors being dug out and rebuilt.
Floor height
Adds the depth of the insulation and the screed.
Heat source
A boiler or a heat pump.
About in screed systems

Overlay

A low profile panel system is installed over an existing suitable floor, with the final floor finish installed above it.

Suits
Renovations and existing floors where digging out is not practical.
Floor height
Adds a small amount.
Heat source
A boiler or a heat pump.
About overlay underfloor heating

Between joists

The underfloor heating system is installed between timber floor joists.

Suits
Properties with timber floors where the boards can come up.
Floor height
Very little is added.
Heat source
A boiler or a heat pump.
About between joists systems

Two ways to work with us

Supply and installation, or installation only

Supply and installation. We provide the complete system, including pipe or cable, insulation, manifold, controls and fixings, and we install it. One point of responsibility for the underfloor heating.

Installation only. The materials are supplied to site by you, your builder or a merchant, and we carry out the installation. This suits projects where a system has already been specified or bought.

Not sure which suits your project? Tell us where things are up to and we’ll advise.

How we work

From first conversation to handover

Every job starts with a conversation about the space, the heat source and the stage you’re at. Where it helps, particularly on retrofits and renovations, we’ll visit to look at the floor build up, the levels and the access.

We then set out the layout, with pipe spacing and circuit runs planned around the rooms, the floor construction and how the space will be used. We fit the pipework or overlay panels, connect the manifold and controls, and pressure test the system before the floor goes back over the top. Once the floor is down we set the system up and show you how to use it.

The exact detail, such as how the design is documented, the controls specified, and what happens at commissioning and handover, depends on the project. Talk to us about the requirements of yours.

Commercial work

Not just homes

Alongside domestic projects we take on commercial underfloor heating installations. If you’re fitting out or building a commercial space and need the underfloor heating handled properly, get in touch and we’ll let you know if we’re a good fit. We’ll add commercial project examples here as they become available to show.

What the work looks like

  • Wet underfloor heating across a large room, ready for screed

    • Wet system
    • In screed
    • Whole room

    A full width wet underfloor heating circuit laid across a large lower level room. Foil faced insulation lines the walls, the floor is built up over insulation and a membrane, and continuous pipe has been clipped in a tight even pattern with edge insulation around the perimeter, set out and ready for the screed.

  • Overlay underfloor heating in a glazed garden room

    • Wet system
    • Overlay system
    • Garden room

    A low profile overlay wet system running through a glazed garden room and into the adjoining space. Grooved insulation panels are laid over the existing floor and the pipe is pressed into the routed channels, so the finished floor level barely changes. A good approach where digging out for a deep screed is not practical.

  • Underfloor heating in a contemporary extension

    • Wet system
    • In screed
    • Extension

    A wet in screed underfloor heating installation in a modern extension with full height sliding glazing onto the garden. Continuous pipe is clipped over insulation in a close even pattern across the whole floor, with blue edge insulation around the perimeter, laid ready for the screed.

  • Underfloor heating in a ground floor extension

    • Wet system
    • In screed
    • Extension

    A wet underfloor heating circuit in a ground floor extension still under construction. Blockwork walls are up to damp proof course, the floor is built up over insulation and a membrane, and pipe is clipped in a wide even pattern with the layout marked out on site, set out ready for screed.

  • Underfloor heating at first fix on a building project

    • Wet system
    • In screed
    • New build

    A wet underfloor heating circuit run across several rooms at first fix stage. Timber stud partitions and blockwork are up, first fix plumbing is in, the floor is built up over insulation and membrane, and continuous pipe is laid in flowing loops from room to room, ready for screed.

  • Low profile overlay underfloor heating fitted in an existing home

    • Wet system
    • Overlay system
    • Renovation

    A low profile overlay wet system fitted through the hallway and rooms of an existing, already plastered house. Grooved foil faced panels sit on the existing floor and small bore pipe is pressed into the channels, carrying the circuit through doorways from room to room with very little change in floor height.

  • Wet underfloor heating installed between timber joists

    • Wet system
    • Between joists

    This wet underfloor heating system was installed between timber joists across several connected areas of an existing property. The photographs show the pipework fitted neatly within the timber floor structure before the final floor finish was installed.

Underfloor heating installation questions

What kinds of underfloor heating do you install?

We install wet, or water based, underfloor heating and electric underfloor heating. Wet systems can be fitted in three main ways: in screed, as an overlay system over an existing suitable floor, or between timber floor joists. Which method is right depends on the property, the floor construction and the project. We work on new builds, extensions and renovations for homeowners, builders and trade customers.

Do you supply the materials, or just fit them?

Either. We can supply and install the complete system, or carry out an installation only job where the materials are provided. Let us know which suits your project.

How much does underfloor heating installation cost?

It depends on the size of the area, the type of system, the floor build up and whether we are supplying the materials. We do not publish prices or estimates, because every project is quoted properly once we understand what is involved. Send us the details and we will come back to you.

Do you give a guarantee?

Talk to us about the cover on your project. It is best explained against the specific system and scope of work rather than in general terms.

How are the controls arranged?

Wet systems connect to a manifold that feeds each circuit, and the controls are set up so that rooms or zones can be managed to suit how you use them. Electric systems use a thermostat for each heated area. We set up the controls and show you how to use them.

Can you fit underfloor heating in an existing house without digging up the floors?

Often, yes. A low profile overlay system sits on top of the existing floor and only adds a small amount of height, so you can heat a room, or a whole floor, without excavating for a deep screed. Whether it is the right approach depends on your floors, door heights and what else is happening in the room. It is a good thing to look at on a site visit.

How long does an installation take?

That varies with the size and type of system and how the project is running around us. We will give you a realistic idea when we quote, and we work to fit in with your programme, particularly on building sites.

What happens once the pipework is down?

We connect the manifold and controls, and systems are pressure tested before the floor goes back over the top. We will set the system up and show you how to use it. For anything specific about what is included at handover on your project, ask us.
