About Our Outside IR35 Quantity Surveyor Contract Roles
What does a quantity surveyor contractor do?
Quantity Surveyor contract work spans across construction, infrastructure, oil and gas, and engineering sectors to manage the commercial and financial aspects of construction projects and contracts, from initial cost planning and budget development through to final account settlement. The QS discipline encompasses cost planning, bill of quantities preparation, tender management, contract administration, variation management, valuation of work in progress, subcontractor management and payment, and the resolution of commercial disputes and claims. QS contractors are deployed by both clients and main contractors, with different commercial perspectives and responsibilities depending on which side of the contractual relationship they represent.
The technical skills expected of Quantity Surveyor contractors depend on the sector and the specific commercial role. Strong knowledge of the relevant contract forms in use, whether NEC, JCT, FIDIC, or bespoke forms for major infrastructure projects, is expected alongside the practical ability to administer those contracts accurately and to identify and protect commercial entitlements within the contract framework. Experience producing and pricing bills of quantities, managing the tender process including evaluation of tender submissions and negotiation, valuing compensation events and variations, and preparing applications for payment and final accounts is the core QS competency profile. MRICS or RICS qualification is well regarded and widely expected for senior QS and commercial management roles, particularly on major public sector programmes where the client-side QS function is subject to specific governance requirements. Proficiency with cost management software, including CostX, COINS, or the relevant client's cost reporting systems, is broadly assumed.
What is the market like for quantity surveyor contractors?
The Quantity Surveyor contract market is a large and reliably busy market, a particularly established contracting disciplines in the UK construction and infrastructure sector. Demand is underpinned by the sustained volume of residential, commercial, and infrastructure construction and the persistent shortage of qualified commercial staff relative to the pipeline of work. Major infrastructure programmes including HS2, Hinkley Point C, National Highways schemes, and large residential development programmes are significant and long-duration sources of QS contract demand. The commercial complexity and contract intensity of modern construction programmes, particularly under NEC, continues to drive demand for experienced QS contractors who can manage contractual entitlements rigorously. RICS-qualified QS contractors are consistently in strong demand and command rates that reflect the commercial responsibility and qualification requirements of the role.
What does Outside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.
Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.
On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What quantity surveyor roles are usually Outside IR35?
Quantity surveying has one of the highest outside IR35 rates of any contracting discipline, at around 65% of contracts with a stated status. Construction's established working model, engaging contractors for defined project phases to deliver cost plans, valuations, or final accounts, aligns naturally with outside IR35 criteria. The QS's professional autonomy over measurement methodology and commercial judgement further strengthens the position. Main contractors, tier one subcontractors, and developer clients generate the bulk of outside IR35 QS demand.
