Defence construction needs Quantity Surveyors who can control cost on programmes where 47 of 49 major projects were delayed or over budget, by the MOD’s own account (Defence Investment Plan, June 2026). A cleared QS keeps commercial control inside the security boundary, so the clearance check matters as much as the cost plan.
Key Takeaways
- The Defence Investment Plan, published on 30 June 2026, backs £298bn of defence investment over four years.
- The Defence Nuclear Enterprise 2026 annual update puts £26bn into Project Royal Oak across naval bases and £7.1bn into HMNB Devonport.
- The UK Quantity Surveyor average base salary is £38,969 across 321 profiles (Payscale, October 2026).
- Senior and Managing QS roles in London and the South East pay £55,000 to £85,000 (Gold Group, March 2026).
- A clearance can transfer only if it’s under 10 years old for SC or 7 years for DV, with no more than 12 months since the holder left their last cleared role (GOV.UK).
Where Cleared Quantity Surveyors Work in Defence
Cleared Quantity Surveyors work on naval bases, nuclear-licensed defence sites and secure estate projects where drawings, schedules or site access sit behind a security boundary. The MOD’s own planning documents show that work is growing fast.
Why do defence Quantity Surveyors need security clearance?
Defence Quantity Surveyors need clearance because cost plans, drawings and programme data on secure sites can reveal sensitive information about the asset being built. The departmental authority responsible for each post sets the vetting level (GOV.UK). A QS who handles that material needs the clearance the post requires, whatever their job title.
On most programmes that means SC, and on some nuclear defence work it means DV. Our guide to the SC clearance process shows how long that vetting takes in practice. Comparing SC and DV clearance timelines helps decide whether a QS post genuinely needs DV.
Which defence programmes are driving QS demand?
Naval base and defence nuclear infrastructure is driving most QS demand. The Defence Nuclear Enterprise 2026 annual update records £26bn for Project Royal Oak across naval bases and £7.1bn for HMNB Devonport. The Defence Investment Plan adds £298bn of investment over four years, 27% higher in real terms by 2029/30 than in 2023/24.
Cost control is the pressure point. The same plan records that 47 of 49 major MOD projects were delayed or over budget, which is exactly the problem a strong QS is hired to fix.
Skills to Screen for in a Defence Quantity Surveyor
A defence QS needs the core commercial skills of any construction QS, plus the discipline to work inside government contract and security rules. Payscale lists commercial, contract management, valuation and procurement as the top QS skills (October 2026).
What makes a defence QS different from a commercial QS?
A defence QS works to government contract terms, tighter audit trails and security controls on information. Valuations, change control and final accounts follow the same principles, but every document may carry a protective marking. The QS must handle that material correctly and keep cost data inside the security boundary.
Experience on public sector frameworks transfers well. Candidates from rail, utilities and nuclear construction often bring the same audit discipline.
Do cleared Quantity Surveyors need RICS membership?
RICS membership isn’t a vetting requirement, but most senior defence QS briefs ask for it. Chartered status (MRICS) shows a QS has passed an independent assessment of professional competence. It matters most on final account disputes, where the client needs a commercial lead whose judgement will stand up to scrutiny.
We check RICS status alongside clearance, because both affect how quickly a candidate can take on sign-off.

Contract QS roles bring IR35 into the cost. The IR35 changes contractors are tracking feed straight into the day rate a client signs.
Inside IR35 work runs through umbrella companies, and the April 2026 rules on joint and several liability made umbrella compliance part of the client’s own risk.

Cleared Quantity Surveyor FAQs
What clearance does a defence Quantity Surveyor need?
The departmental authority responsible for the post sets it, so it depends on what the QS will handle. Most defence QS roles need SC, because cost plans and drawings can carry sensitive information. Some defence nuclear work needs DV. UKSV targets 25 net working days for SC and 95 for DV.
How much does a Quantity Surveyor earn in the UK?
The UK Quantity Surveyor average base salary is £38,969 across 321 profiles, with a range of £27,000 to £53,000 (Payscale, October 2026). Senior and Managing QS roles in London and the South East pay £55,000 to £85,000, often with a £5,000 to £8,000 car allowance (Gold Group, March 2026).
Can a QS transfer their clearance to a new defence employer?
Yes, if the clearance meets the GOV.UK transfer conditions. It must be under 10 years old for SC or 7 years for DV, no more than 12 months can pass between roles, and the holder can’t have lived overseas for more than 6 months during a break in service.
Why is QS demand rising on defence projects?
Defence infrastructure spending is rising fast. The Defence Nuclear Enterprise 2026 annual update records £26bn for Project Royal Oak across naval bases, and the Defence Investment Plan backs £298bn over four years. The same plan records 47 of 49 major projects delayed or over budget.
