Why MCS Umbrella Scheme Standards Matter for Every Heat Pump Installer

Why Choosing the Right MCS Umbrella Scheme Matters More Than Ever

Last week, MCS published the findings of an investigation that shows what can go wrong when companies try to cut corners.

The investigation revealed that several MCS-certified installers were working with an installer that was not certified. Instead of overseeing the work themselves, these certified installers were approving systems they had no part in designing or installing. They then submitted Boiler Upgrade Scheme (BUS) vouchers on behalf of the non-certified installer in exchange for a fee.

In simple terms: the certified installers were helping a non-certified company cheat the system.

They signed off on jobs they didn’t do, submitted government funding claims for work done by someone else, and got paid for it. The non-certified installers may not have realised this was a problem, but the certified installers certainly did. Even if the non-certified installers were unaware, the practice still broke the rules, put customers at risk, and resulted in the certified installers being removed from the scheme.

This type of shortcut damages the reputation of heat pumps and creates real problems for both installers and homeowners. The investigation shows that MCS is taking strong action (a move we fully support) and it highlights why choosing a reliable, fully compliant umbrella scheme is more important than ever.

The problems caused by poor umbrella schemes

When an MCS-certified company signs off work they were not involved in, the risks are significant. Without correct heat loss calculations, system design, oversight or commissioning, there is no way to guarantee that the installation meets MCS standards. 

If something goes wrong, it’s the installer who is left responsible.

Common issues include incorrect sizing, missing documentation, poor system performance, failed audits and rejected BUS applications. In some cases, the homeowner is left with a system that does not operate properly or is unsafe. The installer may then have to return to fix the problems.

This latest MCS investigation shows the consequences of these practices. Companies that offer a quick sign-off service are not providing a true MCS Umbrella Scheme. They are providing paperwork without any of the checks that protect installers and customers.

Why Alto Energy never offers retrospective certification

Over the years, some installers have asked Alto Energy to retrospectively certify heat pump systems after installation. 

We have always refused.

Here’s an example of the type of email we receive, requesting retrospective MCS certification.

There is a simple reason. Retrospective certification goes against MCS rules. It removes the steps that ensure a system is designed correctly from the start. It puts the installer at risk because they end up responsible for a system that may not meet standards. Most importantly, it leaves the homeowner exposed to faults that could have been avoided and undermines public confidence in heat pumps.

By refusing this approach, we protect everyone involved. Our focus has always been on high quality design, full compliance and giving installers the right level of support.

What a compliant MCS umbrella scheme should look like

A proper MCS umbrella scheme should take responsibility for every stage of the process. At Alto Energy, this includes:

  • Full room by room heat loss calculations
  • Complete system design
  • Correct product selection
  • Technical support during installation
  • Commissioning and sign off
  • Creation of the MCS certificate
  • Support with Boiler Upgrade Scheme applications

Our processes ensure the installer has peace of mind. It also means that every job meets MCS compliance and is ready for any audit. Most importantly, it ensures that the homeowner receives a safe, efficient and well designed system.

How to spot a non-compliant umbrella provider

Here are some warning signs that an umbrella scheme might not be trustworthy. These include:

  • Offering to certify systems they have never designed or reviewed
  • Asking for limited information
  • Charging a flat fee simply to sign off a job
  • Promising a BUS voucher without gathering full evidence
  • Refusing to provide detailed calculations or system design documents

If an umbrella provider can’t explain exactly how they work, they probably aren’t following the proper standards. The MCS investigation shows that audits are happening and that shortcuts are being watched more closely.
