For UK installers, MCS compliance isn't optional. It's the difference between accessing government incentives or not.

From the Boiler Upgrade Scheme (BUS V5) to MCS audit packs, ENA Connect G98 and G99 applications, and Building Regulations Part L and Part P sign-offs, Payaca builds compliance into your daily workflow rather than treating it as an afterthought. Configure documentation templates that pull project data automatically, look up EPC ratings by address, and keep every certificate, form, and sign-off organised against the right job.

When auditors arrive, or when you need to file your next BUS voucher, you're ready.

Frequently asked questions

How does Payaca help with MCS compliance?
Payaca lets you configure MCS-compliant documentation using custom fields and HTML templates. Generate customer declarations, commissioning certificates, and handover packs that pull data directly from your projects.
Does Payaca support the Boiler Upgrade Scheme (BUS V5)?
Yes. Payaca captures the photo evidence and commissioning data BUS V5 audits require, and stores it against the project alongside MCS certificates and customer declarations. When Ofgem requests evidence for a voucher claim, the documentation is already organised and accessible.
Can Payaca look up EPC ratings?
Yes. Enter a property address and Payaca fetches the Energy Performance Certificate instantly. Show customers their current rating and use the data in your proposals and compliance documentation.
Does Payaca handle DNO applications?
Yes. Payaca integrates with ENA Connect to submit G98 and G99 applications directly to DNOs. Track application status, generate commissioning forms, and manage the entire grid connection process from within Payaca. See our Grid Connections feature for full details.
Does Payaca capture Part L and Part P sign-off evidence?
Yes. Payaca's custom forms and document storage capture the readings, photos, and engineer sign-offs your Competent Persons Scheme certificate (Part P, Part L) requires. The Competent Person body still issues the certificate, but the supporting evidence lives against the project for Building Control access.
How does Payaca store compliance documents?
All certificates, warranties, manuals, survey packs, and compliance documents are stored against the relevant project. Files can be up to 250MB, in the formats installers work in day to day (PDF, CAD, images, spreadsheets and more). Your team can access them from any device, and everything is organised and audit-ready.
Will Payaca help me pass an MCS audit?
Payaca helps you maintain organised, complete records that MCS auditors expect. With documentation templates, form capture, and centralised file storage, your installation records are always audit-ready.
Can Payaca keep compliance tasks from slipping between jobs?
Yes. Pair task templates with automations and the compliance chain runs itself: when a job reaches the right stage, the DNO application, commissioning, and handover tasks are created assigned by default (to a named person or whoever owns the project) with deadlines already set. The steps that used to depend on someone remembering to fill in two fields now land on the right desk with a clock on them.
