Flexible design support that fits around your existing business.
- Last updated: September 2026
- Heat Loss Hub · For Installers
If you already operate as an MCS heat pump installer, you may not need someone to take over your whole process. You may simply need more design capacity.
Heat Loss Hub provides flexible technical design support for existing MCS installers, from occasional project help and difficult-job support through to regular outsourced design capacity.
You keep your own MCS certification, your customer relationship and your installation process. Heat Loss Hub fits into the part of the workflow where you need extra technical resource.

Already MCS Accredited? Keep Control of the Installation
This service is designed for heat pump installers who already operate under their own MCS certification and want additional design resource without changing the structure of their business.
You remain responsible for:
- Your customer relationship
- Property survey information
- Equipment procurement
- Installation
- Commissioning
- Certification
- Final project compliance
Heat Loss Hub provides the agreed technical design support behind the project. That may mean producing the full design, completing selected parts of it, checking work produced internally or simply providing extra capacity when your own team is busy.
KEY TAKEAWAY
You remain the installer. Heat Loss Hub becomes the design resource behind your business. No umbrella arrangement is required simply to access design support.
Where Can Heat Loss Hub Fit Into Your Workflow?
There is no single outsourcing model that suits every installation company. The design handover can be built around the way your business already works.
You Survey. We Design.
Your team completes the property survey and passes the required project information to Heat Loss Hub. We complete the agreed technical design before returning the project to your team for installation.
You Complete the Heat Loss. We Complete the System Design.
If your team already produces reliable room-by-room calculations, Heat Loss Hub can support the later stages of the design. This might include heat pump selection, flow temperature, emitter design, pipework, hydraulics, hot water and system schematics.
Your Designer Designs. We Review.
If you already employ or contract a designer, Heat Loss Hub can provide independent QA and technical second-opinion support.
You Normally Design Internally. We Provide Overflow.
Your existing process does not need to change. Send work to Heat Loss Hub only when:
- Project volume suddenly increases
- A job is unusually complicated
- Your designer is unavailable
- Recruitment is taking longer than expected
- Your internal backlog starts affecting installation dates
The objective is to add capacity without forcing your business into a completely different workflow.
Work Alongside Your Existing Designer
External design support does not have to replace your internal design team. For many established installers, the best arrangement is a combination of internal and external capacity.
Heat Loss Hub can support your designer with:
- Busy-period overflow
- Complex projects
- Independent design checks
- Second opinions
- Product comparison
- Hydraulic review
- Holiday cover
- Sickness cover
- Temporary staffing gaps
This allows your internal designer to remain focused on the projects where their knowledge of your company and customers adds the most value. Heat Loss Hub deals with the additional workload around them.
Add Design Capacity Without Adding a Full-Time Salary
Design demand does not always grow smoothly. One month your internal resource may be sufficient. The next month you may have twice as many surveys.
That can leave installation teams waiting for designs, quotes waiting for technical information and customers waiting for answers.
Outsourced design support gives you another option between doing everything internally and employing another full-time designer.
Heat Loss Hub can provide extra capacity when:
- Sales increase faster than expected
- Seasonal demand rises
- An installer expands into a new area
- A designer leaves
- Someone is off sick
- Staff are on holiday
- Recruitment is delayed
- A run of technically difficult projects arrives
Add design capacity when you need it, without carrying it when you do not.
Agree the Handover Once, Then Repeat It
Repeat design work should become easier over time. The first project is an opportunity to agree how the handover works. That can include:
- What information your surveyors collect
- Which measurements are required
- Which photographs are needed
- How radiator information is recorded
- How plant locations are documented
- File naming
- Drawing format
- Preferred software
- Design templates
- Communication route
- Revision process
- Final document format
Once those rules are agreed, future projects can follow the same structure. That reduces missing information, repeated questions, survey revisits, design delays, version confusion and inconsistent project files.
The first project establishes the process. Repeat projects should then become easier, not start from scratch every time.
Standardise Survey Information Across Your Team
As installation companies grow, survey consistency can become a bigger problem than calculation capacity. One surveyor may record everything the designer needs. Another may miss:
- Radiator type
- Pipe size
- Cylinder dimensions
- Loft insulation
- Window details
- Proposed heat pump location
- Electrical route
- Plant-space information
Design quality depends on the information arriving at the design stage. Heat Loss Hub can work with you to standardise what is collected before a project is submitted for design. This becomes particularly valuable if several people carry out surveys across the business.
A consistent survey process creates a more consistent design process.
Fit Around Your Existing Software and Project Systems
You may already have a working project-management and design process. The aim is not to replace it unnecessarily.
Heat Loss Hub can work within agreed workflows using platforms such as Spruce and Heat Engineer where appropriate, alongside your existing customer records, survey information, project folders, templates, technical documents and installation files.
The exact process can be agreed during the first projects. What matters is that the information moves cleanly between:
KEY TAKEAWAY
Survey → Design → Review → Installation → Final project file — without creating a second disconnected system that your team has to manage.
Revision and Change Control
Heat pump projects often change after the first design is issued. For example:
- A radiator is moved
- A different emitter is selected
- A pipe route changes
- The cylinder position changes
- The selected heat pump changes
- New site information becomes available
- A room layout is altered
- Existing pipework turns out to be different from the survey
The design needs to remain aligned with the installation. A clear revision process helps everyone know which design is current, what changed, why it changed and whether the change affects other parts of the system.
That may mean moving from Design Rev A to Design Rev B before installation continues.
KEY TAKEAWAY
The design should stay aligned with the job as the job changes. This reduces the risk of the final installation being built from outdated information.
Quality Assurance and Technical Review
You do not have to outsource the design itself to use Heat Loss Hub. We can also act as an independent technical reviewer. This can be useful where:
- Your internal designer wants a second opinion
- The project has unusual hydraulics
- The required flow temperature is high
- The proposed heat pump is close to its operating limit
- The property is difficult to model
- The emitter design is marginal
- Several manufacturers are being compared
- The installation team has raised concerns before work begins
Independent QA can help identify issues before they become site problems.

No Umbrella Scheme Required
If you already hold your own MCS certification, you do not need to hand control of your installation business to an umbrella arrangement simply to access additional design resource.
Heat Loss Hub is there to support your technical workflow. You retain your company, your customer, your MCS relationship, your installation and your processes. We provide the agreed design support behind it.
This can be particularly useful for installers who already have a working MCS process but need more technical capacity.
Start With One Project
You do not need to redesign your whole business before trying outsourced design support. Start with one project.
That allows us to establish how your survey information is supplied, what design work you want completed, what documents you need back, how revisions are handled, which software or templates are used, and how communication should work.
If the process works well, the same handover can then be used for future projects. If you only need occasional help, that is fine too.
START WITH ONE PROJECT
Send us one project and we’ll agree the design scope, information required and handover process before work begins.
