Public Heat Pump & Underfloor Heating Component Price Monitor 2026

Public prices only. These are the foundation numbers we use when building the planning bands in our calculators. Updated quarterly.

Why this page exists

Our calculators are deliberately set as realistic full-installed planning figures for Devon and Cornwall. They start from the public equipment and materials prices below and then add the professional layer (design, labour, electrics, commissioning, access and the practical realities of older South West properties). This page shows the public prices we track so you can see the foundation for yourself.

Air source heat pump kits (public, inc VAT)

Last checked: August 2026 · Sources include The Underfloor Heating Store and manufacturer published lists

Capacity	Complete kit example	What is included
6 kW	£6,617	Grant Aerona3 + pre-plumbed cylinder + install pack
10 kW	£8,196	Grant Aerona3 + pre-plumbed cylinder + install pack
13 kW	£9,060	Grant Aerona3 + pre-plumbed cylinder + install pack
17 kW	£10,157	Grant Aerona3 + pre-plumbed cylinder + install pack

Unit-only prices start lower (Grant bodies roughly £2,700–£5,700). These kits do not include design, labour, electrics, MCS or radiator work. Our full installed bands start from these public kit prices and add the professional layer. See the kit vs installed Reality Check for the full explanation.

Radiator upgrades for heat pumps (public installed ranges)

Last checked: August 2026

Scope	Typical public range	Our planning uplift
Single radiator	£200–£550	—
Partial (3–6 radiators)	£800–£2,400	Many: +£750–£1,250
Full / extensive	£1,500–£5,500+	Full: +£1,500–£2,500

Our Few / Many / Full uplifts sit inside these public ranges as conservative planning figures. See the radiator Reality Check for the mapping.

Underfloor heating systems (public installed £/m²)

Last checked: August 2026

System path	Typical installed £/m²	Typical build-up
Screed (new-build / open floor)	£50–£90	Insulation + 50–65 mm screed
Low-profile overlay (XPS / gypsum)	£80–£150	15–30 mm boards
Suspended / joist	£70–£130	Minimal rise between joists

Material-only board prices are lower. Full installed figures include pipe, manifold, labour and finishing. Our calculator maps these paths and applies realistic planning bands for Devon & Cornwall floor-height realities. See the UFH systems Reality Check.

Controls layer (public component prices)

Last checked: August 2026

Component	Typical public price
Wiring centre (4–8 zone)	£40–£160
Smart thermostat (per zone)	£60–£220 supply
Thermal actuator	£25–£45 each
Secondary return pump	£100–£350 installed
Full multi-zone package	£300–£800+

These form the professional controls layer already allowed for inside our full installed bands. See the controls Reality Check.

Scaffold / access for solar (public ranges)

Last checked: August 2026

Property type	Typical scaffold cost
Mid-terrace / simple access	£350–£500
Semi-detached	£450–£650
Detached / larger	£550–£800
London / complex access	£650–£950+

New-build or concurrent works can share the main construction scaffold and reduce or eliminate this cost. Our solar and combined calculators already apply lower bands when new-build or existing scaffold is indicated. See the scaffold Reality Check.

How these numbers are used

Every planning band in our calculators starts from the public prices on this page and then adds the professional layer required for a proper MCS install in Devon and Cornwall. That is why the figures are set where they are.
