Trade & Subcontract Services

Specialist Subcontracting for Security & Infrastructure Projects

When your project needs a specialist. Whether you're overstretched, out of region or facing a system outside your core competency, Fyrfly steps in as your trusted delivery partner. Standards-compliant, deadline-driven, and completely invisible to your client.

Your Brand, Our Labour We operate entirely under your identity: no Fyrfly branding on-site, no direct contact with your client without your permission
Standards-Compliant Delivery BS EN standards, DfE and public sector compliance built into every installation. Your sign-off, our quality
Deadline-Driven We understand that your reputation rests on delivery. We mobilise quickly, communicate proactively and never miss a handover date without warning
Who We Work With

When You Need a Partner You Can Put Your Name Behind

Most subcontracting relationships fail not because of technical incompetence, but because of poor communication, misaligned standards, and a subcontractor who treats your project as just another job. That costs you client relationships.

Fyrfly operates as a genuine delivery partner, not a transactional labour hire. We understand that when we're on your client's site, we are representing you. Our work reflects on your reputation, and we treat it accordingly.

We work with a select range of partner types: organisations where our technical depth in electronic security, wireless infrastructure and public sector compliance adds genuine value to their delivery capability, without requiring them to hire, train or manage permanent specialists.

Security Installers & System Integrators Capacity overflow, out-of-region projects, or specialist systems outside your core discipline. We fill the gap without you turning work away.
Facilities Management Contractors FM companies managing schools, public estates and NHS sites often need a security specialist they can call on without maintaining a full in-house security team.
Main Contractors & Construction Companies New build schools, healthcare facilities and public sector construction projects frequently require specialist M&E security packages delivered to programme.
IT & Network Infrastructure Companies IT contractors expanding into physical security, or managing site-wide infrastructure projects that include CCTV, access control and wireless networking elements.
Compliance & Surveying Firms Organisations conducting Martyn's Law assessments, DfE security reviews or public sector estate audits that result in a requirement for physical installation works.
What We Deliver

Six Disciplines, One Trusted Partner

Every service we deliver as a subcontractor is identical to what we deliver to our own direct clients: the same standards, the same quality control, the same commissioning documentation. Your client gets a professional installation. You get a clean handover.

Where We Add Most Value

The Projects Other Subcontractors Struggle With

Our background in sensor systems, public sector compliance and technically complex deployments means we're comfortable in the scenarios that trip up generalist installers. These are the jobs where the right subcontractor makes the difference.

Martyn's Law Compliance Projects

Schools and public venues needing to close the gap between their current physical security provision and the requirements of the Terrorism (Protection of Premises) Act 2025. We understand the legislation, design to it, and produce the documentation that satisfies the Responsible Person's compliance obligation.

Multi-Building Campus Projects

School campuses, hospital estates, university sites and local authority building portfolios: multi-building projects where a single coherent security infrastructure needs to span physically separate structures. We design for the whole estate, not just each building in isolation.

Listed Buildings & Heritage Sites

Security installations in listed buildings, Victorian schools and heritage properties where cable routing is restricted and structural intervention must be minimised. Our wireless infrastructure expertise means we can achieve comprehensive CCTV and access control coverage without the cable routes that would compromise a listed structure.

New Build to Programme

Construction projects where M&E security packages need to be designed, installed and handed over within the main contractor's programme. We work to building project timelines, coordinate with other trades, and produce the O&M documentation the client's facilities team needs on practical completion.

System Upgrades & Legacy Migrations

Existing analogue CCTV or outdated access control systems that need upgrading to IP-based infrastructure, often while the building remains in full operation. We manage the transition, minimise disruption to the client's operations, and ensure the new system is fully commissioned before the old one is decommissioned.

Out-of-Region Coverage

You've won a contract in an area where you don't have engineers. Rather than turning the work down or taking a risk on an unknown local installer, use Fyrfly as your delivery partner. We cover projects across England and Wales, with documentation and sign-off processes that integrate cleanly into your own project management framework.

How We Work

Clean, Simple, Professional

We've designed our subcontracting process to be as frictionless as possible for the lead contractor. Four steps from first contact to completed handover, with full documentation at every stage.

01
Initial Briefing

You share the project scope, programme and any existing site documentation. We sign an NDA at this stage if required. No obligation, no cost.

02
Proposal & Pricing

We produce a fixed-price proposal covering labour, materials and documentation deliverables. Clear scope, clear price. No surprises on your client's invoice.

03
Delivery

We mobilise to site, work under your identity, and keep you updated throughout. Any variations are raised with you before they become costs.

04
Handover Pack

Commissioning records, as-built drawings, test certificates, O&M manuals and any compliance documentation: everything your client needs, ready for practical completion.

Your Client is Your Client
We have no commercial interest in your client relationship. We will not contact your client directly without your explicit permission, and we will not solicit further work from them independently. Our relationship is with you.
Fixed Price, No Surprises
We price subcontract work on a fixed-price basis wherever the scope allows. If variations arise on-site, we notify you immediately and agree a change order before proceeding. You will never receive an unexpected invoice after completion.
Standards Compliance Documentation
Every installation comes with a complete documentation pack: commissioning certificates, test records, as-built drawings, and any compliance documentation relevant to the system type and sector. We produce documentation to the standard your client's facilities team and insurer will require.
Public Liability & Professional Indemnity
We carry appropriate public liability and professional indemnity insurance for subcontract work in educational, healthcare and public sector environments. Documentation available on request before any project commences.
DBS Checked Engineers
All engineers working on school and educational premises hold current DBS Enhanced Disclosure certificates. Copies are available to the lead contractor before mobilisation.

Your client is your client. Always.

Why Fyrfly

Technical Depth Most Installers Don't Have

Fyrfly was built by engineers who spent fourteen years developing sensor platforms, IoT architecture and intelligent surveillance systems. That technical depth shows in the quality of what we install and the documentation we produce.

01
Patent-Level Technical Expertise

Our founders hold three granted patents in mmWave radar, acoustic AI and IoT architecture. When your project involves technically complex security challenges: AI analytics, wireless infrastructure, system integration. We've already solved harder problems than this.

02
Education & Public Sector Specialists

We understand DfE security guidance, KCSiE obligations, Martyn's Law requirements and public sector procurement frameworks. Your client's compliance officer will have fewer questions, and the handover will be smoother.

03
Documentation You Can Actually Use

We produce comprehensive commissioning packs, as-built drawings, operator training guides and compliance documentation as standard. Not as an afterthought. Your client's facilities team will have everything they need from day one.

04
Wireless Infrastructure Capability

Most security installers don't have genuine wireless networking expertise. We do, which means we can deliver CCTV and access control in listed buildings, across campus sites and in temporary or remote locations where cabling isn't viable.

05
Transparent, Professional Relationship

We don't chase your clients. We don't undercut you on renewals. We don't disappear after practical completion. We build long-term partner relationships and measure our success by how many times our partners come back.

06
Rapid Mobilisation

Security projects don't always run to an ideal programme. We maintain the capacity to mobilise quickly when a project moves forward unexpectedly, and we'll tell you honestly if we can't, rather than committing and letting you down.
