Heat Pump Readiness Assessment
Before you install a heat pump, find out whether your home can actually run one efficiently. A measured heat-loss survey, fabric and airtightness assessment and emitter review — so a low-temperature heat pump performs as promised, instead of running hot, expensive and disappointing.
What we assess
- Whole-house heat loss (room-by-room) using a measured fabric survey, not a desktop estimate
- Wall, roof and floor insulation levels and the realistic upgrades available
- Airtightness and uncontrolled air leakage that drives up the heat demand
- Thermal bridges and cold surfaces that undermine low-temperature heating
- Existing emitters (radiators / underfloor) and whether they can deliver heat at a low flow temperature
- Ventilation and moisture behaviour as the fabric is tightened
What you receive
- A measured heat-loss figure and an honest readiness verdict — ready now, ready after specific works, or not yet viable
- A prioritised, fabric-first improvement plan to reach the heat demand a heat pump needs
- Guidance on the flow temperature your home could realistically run at
- Emitter and distribution recommendations to support a low-temperature system
- An independent report you can hand to your heat-pump installer or MCS designer
Why fabric first, heat pump second
- Heat pumps are most efficient at low flow temperatures — which only works in a low-heat-loss home
- Reducing heat loss before sizing the heat pump means a smaller, cheaper, quieter unit
- Existing radiators often only work at high flow temperatures unless the fabric is improved
- Airtightness and insulation improvements cut running cost whatever heating you choose
- We are independent of installers — our verdict is about your building, not a sale
Heat Pump Readiness Assessment — common questions
What is a heat pump readiness assessment?+
It is a measured survey that establishes whether your home can run a heat pump efficiently. We carry out a room-by-room heat-loss assessment, review insulation, airtightness and thermal bridging, and check whether your existing radiators or underfloor heating can deliver heat at the low flow temperatures a heat pump needs. You receive an honest readiness verdict and a fabric-first plan to get there.Why do I need a heat-loss survey before installing a heat pump?+
A heat pump is only efficient at low flow temperatures, and that only works in a home with low heat loss. A measured heat-loss survey sizes the system correctly, identifies the fabric improvements that reduce running cost, and prevents the common outcome of an oversized, expensive heat pump running hot in an under-insulated home.Will I definitely need to insulate before a heat pump?+
Not always — some homes are already adequate. But many UK homes, especially solid-wall and pre-2000 stock, benefit from targeted fabric improvements first. Our assessment tells you exactly what (if anything) is needed to reach a sensible heat demand, rather than assuming.Are you independent of heat-pump installers?+
Yes. We do not sell or install heat pumps, so our readiness verdict is about your building, not a product sale. The independent report can be handed to your chosen MCS installer or heat-pump designer.
One company. One process. One point of responsibility.
We don’t simply identify problems. We investigate, diagnose, design solutions, carry out the work and verify the results. Book a Home Health Diagnostic Survey and we’ll tell you exactly which remedial works (if any) are actually needed.
Investigate → Diagnose → Design → Remediate → Verify
RetrofitIQ is not only a diagnostics company. We take projects from first investigation through to verified improvement — and you decide how far we go. Engage us for an investigation on its own, an investigation plus targeted remedial works, or a complete building-performance and retrofit project.
A measured diagnosis — thermal imaging, blower door testing, moisture and building-physics analysis — with a clear, costed report you can act on however you choose.
We investigate, then carry out targeted remedial works — airtightness, insulation, ventilation or thermal-bridge corrections — and verify the result.
A full fabric-first, Passive House-informed retrofit from diagnosis through design, installation and verification — one accountable team, one point of responsibility.
