Occupied properties Phased zones Listed-friendly methods Heat-pump ready Bathroom-priority sequencing A whole-home retrofit installation replaces or supplements your existing wet heating system with low-temperature underfloor heating across every floor we work on, ground floor, first floor, loft conversions, and outbuildings. We design the system around your real living patterns, your floor build-ups, and the way each room is used, then install it in zones so the household keeps functioning while we work. It is the right answer for homeowners who want consistent radiant warmth, freed-up wall space, and a system that will run efficiently on a future heat pump, without selling the house, moving out, or accepting the build-up and disruption of a full new-build approach. We have installed whole-home retrofits in everything from new-build Bramhall semis to Grade II listed farmhouses in Prestbury. You should be thinking about a whole-home retrofit when you are redecorating, swapping flooring, refitting a kitchen, planning a heat-pump install, or simply tired of paying to heat rooms that never feel warm. The technology to retrofit cleanly into existing floors is a generation ahead of where it was even five years ago, but only if the installer knows how to specify it. The Cost of Getting It Wrong ## The biggest risk in a whole-home retrofit is the installer, not the technology. We are routinely called in to fix retrofit UFH projects installed by general plumbers, kitchen fitters, and builders running a sideline. The pipework rarely fails. The design, sequencing, and commissioning almost always do, and the cost of unpicking that work usually exceeds the cost of doing it right the first time. ### Cold rooms after install Heat-loss skipped, pipe pitch wrong, flow temperatures unset, the system runs but the room never reaches setpoint. Owners pay to heat a house that never feels heated. ### Damaged finishes Engineered boards laid before screed cure cycle, tiles laid without de-coupling, LVT laid over inadequate floor flatness. Months later the floor finish lifts and the heating gets the blame. ### Lost grants & lost warranties Heat-pump retrofits installed by non-MCS firms lose the £7,500 BUS grant and the manufacturer warranty in the same week. Pipework warranties are voided if commissioning isn't documented. ### How whole-home retrofits go off the rails. - 01 Quoting from a floor plan alone, with no room visit, no heat-loss model, and no measurement of existing build-ups. - 02 Treating the whole house as one zone instead of designing per room, bedrooms, bathrooms, and open-plan kitchens have wildly different demands. - 03 Skipping interim pressure tests between floors, so a cracked fitting on day three is only found after the screed is poured on day six. - 04 Selling 'smart' controls the homeowner cannot operate and the installer can't service, orphaned ecosystems with no support path. - 05 Disappearing after the invoice clears, leaving no commissioning paperwork, no warranty registration, and no service path. Our Process ## A meticulous, no-mess method. Every project is handled by the same engineers, from first survey through final commissioning, and we're the team you'll call for service for the lifetime of the system. 01 ### Survey & lifestyle interview We visit, measure, photograph existing build-ups, and ask how each room is actually used, not what the floor plan implies. 02 ### Heat-loss model & design CIBSE-compliant per-room heat-loss, pipe-layout drawings, manifold positions, control architecture, and a single fixed-price quote. 03 ### Phased install programme We sequence zones so the kitchen and at least one bathroom stay live throughout, and bedrooms are restored each evening. 04 ### Pipework, manifolds, controls Milled or overlay UFH installed to the design, manifolds plumbed in stainless, controls wired and addressed to the room labels you use. 05 ### Commission, balance, walkthrough Slow cure cycle, every loop balanced and flow-recorded, full handover walkthrough plus an O&M pack and warranty registration.

We have completed whole-home retrofits with toddlers and dogs still in residence. ### Room-by-room comfort Every room reaches setpoint at its own pace. No more freezing en-suite, no more boiling living room. ### Reclaimed wall space Radiators come off. Furniture goes where you want it, not where the plumber decided 25 years ago. ### Heat-pump ready from day one Designed at low flow temperature so it runs efficiently on an ASHP, now or whenever you choose to switch. ### Long-tail running cost savings Larger emitter area means lower flow temperatures, longer cycles, lower bills, typically 18–35% less than the radiator system replaced. ### One contract, one warranty, one team We design, install, commission, and service. There is no second contractor to blame when something needs attention. Technical Detail ## What 'whole-home retrofit' actually involves under the floor. A retrofit programme is rarely a single technique. We blend milling, overlay, and joist-void installation across the same house, choosing the right method floor-by-floor and room-by-room. Here is what that actually looks like. ### Ground-floor solid slab (milled) Concrete or screed subfloor is milled to depth, pipe is bedded and encapsulated, finish goes back over the top. Build-up rise: zero. Perfect for kitchens, living spaces, and entrance halls where door thresholds matter. ### First-floor timber joist We lift floorboards by section, route or insulate joist voids, install spreader plates with 12 mm or 16 mm pipe, and reinstate the boards. No new floor build-up, no ceiling damage below. ### First-floor overlay Where lifting boards isn't viable, we use 18–22 mm grooved high-density overlay panels with aluminium spreader plates. Adds minimal build-up; perfect for landings and bedrooms. ### Bathroom & wet-room specials Underfloor heating below tanked wet rooms uses low-modulus encapsulation, decoupling membranes, and dedicated thermostats rated to IP-zone requirements. ### Controls & zoning architecture Wired or wireless thermostats per zone, central wiring centre, OpenTherm or 0–10 V interface to the heat source. Compatible with Hive, Tado, Nest, Heatmiser, and Loxone. We avoid proprietary lock-in. ### Heat source pairing Combi boiler, system boiler, ASHP, or hybrid, we size the loop, manifold, blending valve, and weather compensation so the heat source runs in its efficient band, not flat-out.

Will the heating be louder, quieter, or the same?+ Significantly quieter. No thermosiphon clicks, no boiler short-cycling, no radiator expansion noise. Most clients tell us the only way they know the heating is on is the house feeling comfortable. Will it raise the floor level?+ Milled installs: zero rise. Joist-void: zero rise. Overlay panels: 18–22 mm, usually absorbed in a flooring change anyway. We always show the proposed build-up at survey. What happens if something fails ten years from now?+ Same team, same number.
