Current credentials, backed by project-specific evidence
NW Heating Services has confirmed the six credentials and installer relationships shown below as current, and has authorised their logos for this website. Ask us to show the registration evidence relevant to your proposed work.
Qualified routes for heating and renewables
Current status and logo use were confirmed by the business owner on 12 August 2026. Registration details relevant to a proposed project are available on request.
Evidence a homeowner should expect
- Current MCS certification for the relevant technology when using BUS
- Consumer-code membership and clear contract protections where required
- 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.
Check current evidence for the exact work
Certification, consumer protection, manufacturer competence and trade qualifications apply to different parts of a project. Ask which business carries the contract, who owns the heat-loss design, which registrations cover the proposed technology and whether subcontracted electrical, refrigeration or ground work is included. A logo alone is not enough: current identifiers, scope and expiry should be available before commitment.
A sound project keeps responsibility visible through survey, design, installation, commissioning and aftercare. If several specialists are involved, the proposal should explain who coordinates their work and who the homeowner contacts when a design question, programme change or fault needs resolving.
Ask for a complete written scope
Check the property assumptions, heat demand, proposed water temperatures, emitter and cylinder changes, controls, outdoor or ground works, electrical requirements, permissions, warranty conditions, commissioning records and maintenance route. Confirm which items are included, provisional or excluded and how changes will be agreed.
Funding should be shown separately from engineering suitability. Where the Boiler Upgrade Scheme is relevant, the installer-led process and applicable Ofgem category should be confirmed before the grant is relied upon. Retain the design and handover documents so future adjustments begin with evidence.
