Verify the route, not just the badge
Heat-pump design, funding and installation involve specific standards and consumer protections. Ask for current evidence before signing—not a logo without a registration number.
Evidence a homeowner should expect
- Current MCS certification for the relevant technology when using BUS
- Consumer-code membership and clear contract protections
- A room-by-room heat-loss calculation and emitter schedule
- Manufacturer and trade competence relevant to the work
- Commissioning, warranty, maintenance and aftercare responsibilities
What our proposal should explain
- 01
The design heat load and assumptions
- 02
Emitter outputs and intended flow temperatures
- 03
Hot-water, controls, siting and electrical requirements
- 04
Grant pathway and current eligibility evidence
- 05
Installation, commissioning and aftercare scope
Ask us for the evidence relevant to your project
We welcome informed questions about design responsibility, standards and aftercare.

Questions worth asking before commitment
Ask the proposed designer to show the room-by-room heat loss, emitter outputs at the intended flow temperature, hot-water assumptions, outdoor-unit acoustic assessment and the control strategy. Ask which current registrations apply to the exact work and verify them through the relevant scheme or certification body rather than relying on a logo alone.
The written scope should distinguish survey, design, equipment, enabling works, electrical supply, radiator or underfloor changes, commissioning, warranty and ongoing care. It should also explain exclusions and who is responsible if site evidence changes the design. Clear evidence protects both homeowner and installer and makes quotations easier to compare on substance.
Evidence before acceptance
Registration, scheme eligibility and product-specific competence can change. Current evidence should be checked for the technology and scope at the point a quotation is accepted, with copies retained alongside the design and commissioning records.
