How to Start a Construction Project Management Company in the UK
Construction project management is one of the most in-demand skills in the industry – and one of the most accessible business models for experienced construction professionals who want to work smarter rather than harder. As a project manager, you’re not swinging a hammer. You’re coordinating the people who do, managing the programme, controlling costs, and keeping the client informed.
This guide is for construction professionals – site managers, quantity surveyors, contracts managers, or experienced tradespeople – who want to set up their own project management consultancy or contracting business.
What Does a Construction Project Management Company Do?
A construction PM company can operate in several ways:
Pure consultancy – you provide project management as a service. The client holds contracts with all the trades. You manage the programme, the budget, the quality and the communication. You don’t employ anyone directly and carry no contractor liability.
Principal contractor – you hold the main contract with the client, subcontract all trades, and take overall responsibility for delivery. Higher risk, higher margin, more complex.
Employer’s agent / contract administrator – you act on behalf of the client in administering JCT or NEC contracts. Requires strong contracts knowledge and typically professional indemnity insurance.
Most new construction PM businesses start as consultancies and move into principal contracting as they build a track record and financial strength.
Qualifications and Credentials That Matter
Unlike hands-on construction work, PM is a knowledge-based discipline. The credentials that carry the most weight:
MCIOB (Member of the Chartered Institute of Building) The most recognised professional qualification for construction project managers. Demonstrates competence, professionalism and commitment to CPD. Increasingly required or strongly preferred on significant commercial projects.
APM PMQ or PMP General project management qualifications. Less construction-specific than CIOB but widely recognised and useful for clients from outside the construction industry.
RICS (Royal Institution of Chartered Surveyors) If you have a QS background, MRICS membership signals strong cost management capability – highly valued by developers and commercial clients.
PRINCE2 or MSP Framework-based qualifications more common in public sector construction. Useful for clients with a strong methodology preference.
CDM Coordinator / Principal Designer competence Under CDM 2015, the Principal Designer role on notifiable projects requires demonstrated competence. This is a significant commercial opportunity for PM companies.
Setting Up the Business
Business structure: A limited company is almost always appropriate for a PM consultancy. Clients want the credibility, contracts require it, and personal liability on large projects is a real risk worth limiting.
Professional indemnity insurance: Essential. Your errors and omissions can have significant financial consequences on a construction project. Minimum £1m, typically £2-5m for commercial work. Check that your policy covers the specific services you offer.
Contracts: You need professionally drafted terms of engagement for your consultancy services. Don’t use generic templates – construction PM has specific risks and liabilities that need to be addressed. Get a solicitor to draft or review your standard contract.
Registration: Consider registering with Constructionline and relevant professional bodies early. Commercial clients use these to pre-qualify consultants.
Finding Your First Clients
The PM consultancy market is relationship-driven more than almost any other construction sector. Your first clients will almost certainly be developers, contractors or clients you already know.
Developer network: Property developers are the most natural clients. A developer managing multiple residential or commercial projects will value a trusted PM who can run projects on their behalf. Build relationships with local developers through industry events and introductions.
Main contractors: Large contractors sometimes outsource PM on specific projects. Your background as a contractor can be a genuine selling point here.
Local authorities and housing associations: Public sector bodies regularly appoint external project managers and employers agents. Require pre-qualification (Constructionline, CHAS etc.) but offer consistent volume.
Estate agents and property managers: Commercial property managers often need PM support for refurbishment and fit-out projects.
Fees and Day Rates
Construction PM fees are typically structured as:
- Percentage of project value: 3-8% for residential, 2-5% for commercial depending on scale and complexity
- Fixed fee: Negotiated per project based on estimated hours
- Day rate: £350-700/day for experienced PMs, higher for specialist roles
Be careful with percentage-based fees on projects where the scope may grow – make sure your fee adjusts proportionally.
Frequently Asked Questions
Do I need to be a builder to start a construction PM company? No – but you need credible construction experience. PM is a people and process discipline, but you need sufficient technical knowledge to manage programmes, understand drawings, assess progress and challenge professionals when needed. Most successful construction PMs have hands-on site experience.
What’s the difference between a project manager and a main contractor? A project manager acts on behalf of the client and coordinates others. A main contractor holds the building contract, employs or subcontracts the workforce, and is responsible for delivery. You can be both, but they’re legally and commercially distinct roles.
How much can a construction PM company earn? A sole practitioner running 3-4 projects simultaneously can earn £80,000-150,000 per year at market day rates. Scaling to a small team managing 10-15 projects across a region can generate £500,000-1m+ in fee income.
Do I need professional indemnity insurance? Yes. If your advice or management leads to a cost overrun, programme delay or defect, the client may hold you liable. PI insurance protects you from professional negligence claims. It’s non-negotiable for any PM operating commercially.
