Last updated: 13 August 2026

Construction rarely happens at a desk. Your teams work from temporary sites that change as projects move, so connectivity and device management have to work away from a fixed office.

A single project can pull together a main contractor, subcontractors and consultants, all sharing drawings and project data across different organisations. And the sector moves large, scheduled payments between those parties, which makes invoice fraud and payment redirection a real risk. An IT provider working with construction firms needs to handle all of that, not only office desktops.

This page lists providers who work with construction firms. Providers holding the Assurix Trusted MSP badge are shown first, and any working toward it appear as On the Journey. Below is what to look for and what to ask before you choose.

What to look for in a provider

A provider who understands construction thinks beyond the head office to the sites, the supply chain and the money moving between them.

Works away from a fixed office
Your people are on sites that come and go. Ask how a provider handles connectivity and device setup at temporary locations, because a lot of construction IT problems happen where there's no permanent office to fall back on.
Mobile and site devices
Phones, tablets and laptops move between sites and get used in rough conditions. A capable provider can manage and secure devices remotely, so a lost or stolen one on site doesn't put project data at risk.
Shared project data
Drawings and project files get shared between main contractors, subcontractors and consultants. Look for a provider who can set up controlled ways to share data with people outside your own organisation.
Guards against payment fraud
The sector handles large scheduled payments, which makes invoice fraud and payment redirection a recognised risk. Ask how a provider helps protect against fraudulent emails and changed bank details.
Ready for pre-qualification
Main contractors increasingly pass security requirements down to their subcontractors. A provider who keeps good records makes pre-qualification questionnaires much easier to complete.

Questions worth asking

These questions get at the parts of construction IT that a general provider often misses.

  1. How do you set up IT and connectivity on a new temporary site? Most construction work happens away from a fixed office, so this is where problems tend to appear.
  2. How do you secure phones and tablets that move between sites? Site devices get lost or damaged, and remote management keeps project data safe when they do.
  3. Can you set up safe ways to share drawings and files with subcontractors and consultants? Project data crosses organisations constantly, and uncontrolled sharing is a common weak point.
  4. What protection do you offer against invoice fraud and payment redirection? The sector moves large scheduled payments, which makes it a target for this kind of fraud.
  5. Can you help us complete security pre-qualification questionnaires? Main contractors increasingly require these before awarding work, so it affects which jobs you can win.
  6. How do you handle data shared inside a joint venture or framework? These arrangements share information with organisations that aren't your employees, so the rules need to be clear.

The risk picture in construction

Construction puts unusual demands on IT. Firms work across temporary sites, so connectivity and device management have to happen away from a fixed office. The workplace changes with every project, and the technology has to follow.

Projects are collaborative by nature. A single job can involve a main contractor, subcontractors and consultants, all sharing drawings and project data across separate organisations. Joint ventures and project frameworks push that further, with information shared between parties who aren't employees of any one firm. That makes controlled data sharing a genuine concern.

Money is a risk of its own. The sector handles large, scheduled payments between parties, which makes payment redirection and invoice fraud a recognised risk. A fraudulent email changing bank details at the wrong moment can be very costly. There's a commercial layer too. Main contractors increasingly pass security requirements down to their subcontractors, so the ability to show how your systems are protected now affects which contracts you can bid for.

What the Assurix Trustmark means here

Assurix is an independent trustmark for UK IT providers, working on a simple principle: proof, not promises. When a provider carries the Trusted MSP badge, it has passed all 64 controls, mapped to the NCSC Cyber Assessment Framework, with continuous monitoring behind it rather than a single annual check. For a construction firm juggling sites, subcontractors and large payments, that steady evidence is worth weighing alongside the questions you put to a provider directly.

Frequently asked questions

How is IT support for construction different from a normal office?

The biggest difference is location. Construction firms work across temporary sites that appear and disappear with each project, so connectivity and device management have to work away from a fixed office. Beyond location, project teams share drawings and data with subcontractors and consultants from other organisations, and the sector moves large payments that attract fraud. A provider used to a single fixed office won't necessarily handle all of that, so sector experience counts for a lot.

Why is construction a target for invoice fraud?

The sector handles large, scheduled payments between main contractors, subcontractors and suppliers. Those payments are often expected, so a fraudulent email asking to change bank details can slip through more easily than in a business where a big payment would stand out. Payment redirection and invoice fraud are a recognised risk as a result. A good IT provider helps by putting checks around email and by making staff aware of how these scams work, so a changed bank detail gets verified before any money moves.

What are pre-qualification questionnaires and why do they mention security?

Pre-qualification questionnaires are the checks a main contractor runs before awarding work to a subcontractor. Increasingly they include questions about how you protect your data and systems, because main contractors are passing their own security requirements down the chain. If you can't answer clearly, you can be ruled out before the real bidding starts. A provider who keeps good records of how your IT is protected makes these forms far quicker to complete and improves your chances of getting through them.

How do you keep project data safe when it's shared with other companies?

Construction projects share drawings and files across main contractors, subcontractors and consultants, and joint ventures spread data further still, to organisations that aren't your employees. The aim is controlled sharing: the right people see what they need, and access can be removed when someone leaves the project. A provider can set up shared spaces with proper permissions rather than files being emailed around freely. Ask any prospective provider how they'd manage sharing across a project team that spans several firms.

What does the Assurix 'On the Journey' status mean?

On the Journey means a provider has started working towards the Assurix Trusted MSP badge but hasn't passed yet. It's time-limited to six months and it isn't a pass, so it shouldn't be read as one. It shows the provider has chosen to begin the process. Providers with no status are simply not yet Assurix-verified, which isn't a mark against them: plenty are strong firms that haven't been through it.
