Do I Need a Quantity Surveyor as a Subcontractor?

Do You Actually Need a Quantity Surveyor?

If you are running a specialist subcontracting business in the UK – whether in MEICA, groundworks, M&E, steelwork, cladding, piling, civils or any other trade – there is a good chance you are leaving money on the table because you do not have proper quantity surveying support. The question is not really whether you need a QS, but whether you can afford not to have one.

Most subcontractors under about £5 million turnover do not employ a full-time quantity surveyor. The contracts manager, site manager or business owner handles the commercial side alongside everything else. Payment applications get submitted late or are undervalued. NEC compensation events go unnotified because nobody spots them or has time to deal with the paperwork. Variations are not properly recorded. Final accounts get settled for less than the work was worth because nobody has the time or expertise to negotiate properly.

What Does a Quantity Surveyor Actually Do for a Subcontractor?

A QS for a subcontracting business handles the financial and contractual side of your projects. The core tasks include preparing and submitting payment applications that comply with your subcontract and maximise your entitlement, identifying and notifying NEC compensation events within the eight-week deadline, recording and valuing variations, managing contractual correspondence with the main contractor, preparing cost-value reconciliations so you know whether each project is making or losing money, and preparing and negotiating final accounts.

A good QS will also review your subcontracts before you sign them (identifying onerous terms and negotiating amendments), help with tender preparation, manage retention release and recovery, and escalate disputes to adjudication when negotiation fails.

Signs You Need QS Support

You almost certainly need quantity surveying support if any of the following apply to your business: your payment applications are regularly disputed or undervalued, you are not notifying NEC compensation events, you are not sure whether your projects are making or losing money, your final accounts are always settled for less than you expected, you are owed retention that has not been released, you have disputes with main contractors that are not being resolved, or you are growing and taking on larger or more complex packages.

Outsourced QS vs Full-Time Hire

A full-time quantity surveyor costs roughly £45,000 to £65,000 per year in salary alone, plus employer's NI, pension, office costs and management time. For many SME subcontractors, that is a significant overhead that cannot be justified unless you have a consistent workload of £3-5 million per year or more.

An outsourced QS gives you the same expertise on a flexible basis – typically one or two days per week, or on a project-by-project basis. At a day rate of £350 to £800 depending on experience, you might spend £1,500 to £3,000 per month for regular support. That is a fraction of the full-time cost, and you can scale up or down as your workload changes.

The financial return on QS support is almost always positive. A good QS will recover more in additional compensation events, properly valued variations and improved payment application management than they cost in fees. It is not unusual for a QS to recover tens of thousands of pounds in the first few months of an engagement simply by addressing the commercial issues that were being missed.

How to Choose the Right QS for Your Business

Look for a QS who has practical experience working with subcontractors (not just main contractors or clients), who understands the specific contract forms you work under (NEC and JCT are the most common for UK subcontractors), and who has experience in your trade sector. A RICS qualification is a good indicator of competence and professionalism. Ask for references from other subcontractors they have worked with.
