ONE COORDINATED TEAMPlumbing · Heating · ElectricalFrom first fix to handover

A comfortable finish starts with the decisions made underneath it.

We work with Wunda Group to supply matched water-based systems at competitive project prices, with the installation planned around your home, your chosen flooring and the parts of the heating system you want to retain.

01 · Plan before the floor goes down

Plan the heating before the new floor goes down

A refurbishment creates an opportunity to change how your home feels. It also creates a deadline: once the kitchen, thresholds and final floor finishes are fixed, heating decisions become harder to revisit.

That is why we start with the renovation as a whole.

You may be updating several rooms in a Northfields home while leaving the upstairs radiators untouched. You might be replacing the ground-floor finishes near Pitshanger, or considering a warmer bathroom in an Ealing Broadway flat. Each project needs a different installation plan.

We establish which floors are being opened, what can remain, where the heating connections will run and how the work fits around other trades. If the renovation is phased, the design should consider the intended final arrangement before the first room is completed.

This helps avoid an attractive new floor concealing compromises that could have been resolved at the planning stage.

02 · The right system for the room

Wet or electric underfloor heating?

Water-based heating for connected living spaces

Wet underfloor heating circulates warm water through pipework beneath the floor. It is worth considering for larger areas, several adjoining rooms or a wider renovation where the heating can be designed alongside the floor construction.

The pipework is only one part of the installation. The manifold, heating connection, circulation arrangements and controls must all support the required room temperatures.

We assess the available heat source and the proposed floor assembly before recommending a water-based system. Keeping a suitable existing boiler can be entirely reasonable; changing the floor heating does not automatically mean replacing everything else.

Electric heating for carefully selected rooms

Electric mats or cables can be a practical option for a bathroom or another targeted area, particularly where extending the wet system would involve substantial work elsewhere.

The available electrical supply, usable floor area, insulation, floor sensor and finish all need consideration. A warm tiled floor and a system capable of heating the entire room are not necessarily the same specification.

Installation cost and running cost should also be considered separately. The better choice depends on the room, its use and the wider energy arrangements in your home.

03 · Four constructions. Four approaches.

Four installation methods, chosen around your floor

01 · Retained substrates

Low-profile overlay systems

Where the existing structural floor is suitable, grooved panels can accommodate water-based heating above it. This can provide a retrofit route without excavating the entire floor.

We check the substrate, preparation requirements and the complete assembly beneath the proposed covering. Low-profile panels can help with height constraints, but they do not remove the need to plan thresholds, doors and adjoining rooms.

02 · New floor construction

Underfloor heating within a new screed

When a floor is being built or substantially reconstructed, pipework can be incorporated into a specified screeded assembly over insulation.

The insulation, pipe layout, movement details, screed and final finish need to work together. Testing, curing and the initial heating programme also belong in the building schedule: laying the pipes is not the final stage.

03 · Suspended timber floors

Systems for suspended timber floors

Where access and construction allow, a joisted system can place the heating within the timber floor structure, using appropriately specified heat-transfer components.

Insulation beneath the heating, contact with the floor above and sensible pipe routes are essential design considerations. We assess the existing structure and services rather than treating joists as convenient places to cut a route.

04 · Selected rooms

Electric mats and heating cables

Electric systems are selected for the particular room and compatible floor assembly. Their layout must account for fixed fittings, manufacturer-required clearances, sensor positioning and the electrical connection.

Our guide to retrofitting underfloor heating in an existing home explains the construction choices in more detail.

04 · Every layer counts

Measure the finished floor — not just the heating panel

A few millimetres can matter at a doorway, beneath an appliance or where a new floor meets a staircase.

The relevant measurement is the full finished level. Depending on the system, this may include preparation, insulation or heating panels, levelling layers, adhesive, underlay and the final covering.

We consider those layers together before the installation is agreed. Changing the floor finish later can affect both the level and the heating performance, so it is worth sharing the exact product specification early.

Suitable tiles, stone, engineered wood, laminate, LVT and some carpet assemblies can work with UFH, subject to their individual requirements. Thermal resistance, fixing methods and temperature limits must be checked for the chosen products. Wunda’s floor-covering guidance sets out why compatibility is product-specific.

In a flat, any required sound-separation measures must also be compatible with the complete floor construction.

05 · Comfort starts with the heat requirement

Will the floor provide enough heat?

The right question is not simply how many square metres of pipework will fit. It is whether the available heated floor can meet the room’s heat requirement.

We consider room-by-room heat loss, usable heating area, insulation, glazing and the proposed finish when developing the installation scope. A kitchen island or fixed bathroom fittings can reduce the active floor area substantially.

Where UFH alone cannot provide the required output within the permitted operating limits, the design may need a supplementary radiator or towel rail, or improvements to the building fabric.

This assessment should happen before removing existing emitters. Turning the thermostat higher cannot compensate for an undersized heating surface.

06 · A whole-home heating decision

Keep what works. Connect the new heating properly.

Many renovations do not need a completely new heating system. Water-based UFH downstairs and retained radiators elsewhere can be a sensible arrangement.

However, the circuits may operate at different temperatures and respond at different speeds. Their pumps, valves and controls need to work with the heat source, including when only a small area is calling for heat.

We assess the proposed demand, existing connections and control strategy before specifying the interface. Mixing equipment or hydraulic separation is included where the design requires it, not treated as a universal shopping list.

If a boiler change forms part of the project, our boiler installation service in Ealing allows that decision to be coordinated with the UFH design. For more extensive changes, we also undertake central heating installation and plant-room work.

Tell us if a future heat pump is part of your plans. Designing for lower operating temperatures can inform the current choices, but future compatibility still depends on the building and the complete installation.

07 · Matched supply. Coordinated installation.

Complete Wunda packages, coordinated by PEP

PEP works with Wunda Group to supply complete, matched water-based underfloor heating packages at competitive project prices.

This means considering the selected floor system alongside its pipework, manifold, actuators, thermostats and associated controls. The specification should reflect the rooms being heated and the arrangement being installed, rather than starting with a generic kit and resolving the differences on site.

We coordinate supply with the installation programme and clarify the connections to existing heating, electrical work and surrounding floor construction.

Manufacturer warranties apply to the relevant products and their conditions. Those terms are separate from the agreed installation scope and should be clear when the system is selected.

08 · From the first plans to handover

From the first assessment to the final settings

1. Understand the rooms and the renovation

We review the intended layout, floor construction, finishes, heat source and access. Available plans and photographs help identify the main decisions before a detailed installation scope is agreed.

2. Agree the design and responsibilities

The floor build-up, heating requirements, manifold position, zones and connection arrangements are developed together. We establish what PEP will carry out and what your builder, screeder or flooring contractor needs to provide.

3. Install and check before covering

The installation follows the selected system’s requirements. Wet circuits are pressure-tested before concealment; electric systems require their specified checks at the relevant stages. Results and installation details form part of the agreed project records.

4. Coordinate curing and floor finishes

Where screeds, adhesives or levelling compounds are involved, their readiness for heating and floor laying must be confirmed. The programme follows the relevant product requirements, not a standard promise that every floor will be ready in the same number of days.

5. Commission and explain the controls

We commission the installed heating arrangement, check zone operation and set up the controls within the agreed scope. For wet systems, balancing and flow settings help distribute heat as intended. At handover, we explain the settings, operating approach and applicable documentation.

09 · Practical control. Useful comfort.

Controls that suit the way you use the house

A family kitchen used throughout the day has a different routine from a guest bedroom or an occasional-use bathroom.

We consider how rooms should be grouped, where sensors should be positioned and how the heating should respond to demand. More thermostats do not automatically create a better installation; the zones must suit the system as well as the occupants.

Smart controls can add useful scheduling and remote adjustment, but compatibility with the heat source and heating circuits comes first. A slow-response floor also needs an operating approach suited to its construction.

Our guide to smart heating controls explores zoning, integration and practical control choices.

10 · Compare the complete scope

What affects underfloor heating installation costs in Ealing?

The cost depends on what needs to happen around the heating as well as the area being heated.

An open floor ready for installation presents a different scope from a finished room requiring careful removal, repairs and reinstatement. A small project can still involve substantial preparation or a difficult connection route.

The main considerations include:

The heated area, number of rooms and zones.
The installation method and condition of the existing floor.
Insulation, acoustic requirements and finished levels.
Manifold location, pipe routes and heat-source connections.
Electrical supplies, controls and commissioning.
Access, protection and the sequence of work.
Screeding, floor finishes and making good.

Our proposal identifies the agreed UFH work and distinguishes associated items, exclusions and matters requiring further investigation. That gives you a more useful basis for comparison than a headline price for pipework or panels alone.

Where an existing heating circuit is being retained, its condition needs checking. Heating-system cleaning in Ealing may be appropriate if contamination is identified; a powerflush is not an automatic requirement for every new UFH installation.

11 · Plumbing, heating & electrical

One coordinated scope for the refurbishment

Floor heating often overlaps with a new kitchen, bathroom alterations or changes to the heating cupboard. Coordinating these decisions early helps keep connection routes accessible and reduces the risk of completed work being reopened.

PEP brings together plumbing, heating and electrical installation. Our plumbing services in Ealing cover associated pipework and installation needs, while our electrical services support the relevant supplies and controls.

We can work alongside your builder, architect and flooring contractor, with responsibilities agreed before installation. In leasehold or protected properties, any required permissions and restrictions should also be resolved before the work begins.

Before you plan the work

Your underfloor heating questions answered

Can you fit UFH without excavating the whole floor?

Often, an overlay or another retrofit system can avoid full excavation. Suitability depends on the existing substrate, available height, required output and finish. The preparation and insulation requirements still need assessment.

Can I keep my boiler and upstairs radiators?

Potentially, yes. We assess their condition, capacity and compatibility with the proposed arrangement. Suitable existing equipment can remain, with the UFH connections and controls designed to work alongside it.

How much will the floor level rise?

There is no single figure for every system. The full build-up includes preparation and intermediate layers as well as the heating and final covering. We establish the proposed level before agreeing the installation.

Can UFH go beneath a timber floor?

Appropriate systems can work with suspended timber constructions and suitable wood finishes. The joists, insulation, heat transfer and flooring specification must be assessed together; the material name alone does not establish compatibility.

Is electric UFH worthwhile for one bathroom?

It can provide useful comfort without extending water-based pipework into the room. We check the electrical requirements, usable area and intended heating duty, including whether a towel rail or other supplementary heating should remain.

Can we stay at home during installation?

Sometimes work can be phased, but this depends on the rooms, access and associated floor works. We discuss protection, temporary access and likely heating interruptions before agreeing the programme.

How long before a new screed can be heated?

The timing and first-heating sequence depend on the screed product and installation conditions. Floor-covering readiness is a separate consideration. Follow the agreed product-specific programme rather than a universal drying period.

Does poor performance mean the UFH needs replacing?

Not necessarily. Controls, actuators, circulation or settings can cause problems. Diagnosis comes first; our guide to underfloor heating that is not working explains the main possibilities.
