Building Surveyor vs Quantity Surveyor: Work, Training and Pay

Building surveyor vs quantity surveyor

UK guide · last reviewed September 2026

Building surveying and quantity surveying are the two most common routes into chartered surveying, and many students and career changers weigh up both. In short: building surveyors deal with the physical building, its condition, defects and repairs, while quantity surveyors deal with the money, from cost plans and tenders to valuations and final accounts. Both are in short supply, and it's possible to switch later. This guide compares the work, training and pay.

What each does

Building surveyors inspect buildings and diagnose defects, write condition and pre-acquisition surveys, prepare specifications and run refurbishment projects as contract administrator or project manager, and advise on dilapidations, party walls, maintenance planning and more. Prospects describes the role as much less desk-bound than other surveying jobs. See what a building surveyor does.
Quantity surveyors manage the cost of construction projects: early budgets and cost plans, procurement advice, tender documents, measuring and pricing work, valuing progress and changes during the build, and agreeing the final account. Some handle claims and disputes.

Where each works

Building surveyors mostly work for property consultancies, housing associations, councils and other public bodies, and organisations that own a lot of property. Some work for insurers or contractors.

Quantity surveyors work on one of two sides. Consultant-side (or client-side) QSs work for consultancies, developers and public bodies, advising the client, and are mostly office-based. Contractor-side QSs work for building contractors and subcontractors, managing the contractor's costs and income. That work is more site-based, often with longer hours and more pressure.

QSs on r/quantitysurveying mostly agree on the trade-off: contractor side pays more, while consultant side has a better work-life balance and more hybrid working. The common advice is to start on the contractor side, where you learn how buildings actually get built and paid for, and move to consultancy later, as that move is easier than the reverse. Experienced contractor QSs often take a pay cut to move to a consultancy for less pressure.

Which suits you?

Building surveying suits you if you're interested in how buildings work and fail, like being out on site, enjoy solving problems, and don't mind variety. The role is broad and leads on to project management, development and building control.
Quantity surveying suits you if you're comfortable with numbers, contracts and negotiation, and are commercially minded. QSs say the maths is GCSE level (adding up, multiplying, percentages, areas and lengths), but you need to be accurate and good at measuring from drawings. It also travels well: QS roles are much more common abroad, for example in the Middle East, where building surveying is less recognised.

Both subreddits say much the same. On r/buildingsurveying, quantity surveying is seen as better paid but more stressful and desk-bound. On r/quantitysurveying, the most common complaints are spreadsheets, pressure and, for some, boredom, while people who enjoy it value the pay and dealing with people. Some QSs look at building surveying or project management to get out of the office. If you're still deciding, ask building surveyors about their work on r/buildingsurveying.

Training and qualifications

Degrees. Both need an RICS-accredited degree, or an accredited conversion master's if your degree is in another subject. Some universities share the early years: at Reading, building surveying, quantity surveying and construction management students take a common first two years and can switch at the end of the second year.
Apprenticeships. The Chartered Surveyor degree apprenticeship covers both, with separate pathways. There's also a contractor-focused Construction Quantity Surveyor apprenticeship. See the apprenticeships guide.
Chartership. Both qualify through the RICS APC, on different pathways: Building Surveying, or Quantity Surveying and Construction. See the APC guide. Chartership matters more for building surveyors, whose pay tends to be held back until they qualify. Plenty of contractor-side QSs reach senior, well-paid roles without it, and some join CIOB instead.

Can you switch later?

Yes, especially early on. The APC pathways overlap: contract practice, procurement, quantification and cost planning are optional competencies for building surveyors, and construction technology is core for both. But it's easier in one direction. Plenty of people with building surveying degrees work as QSs, and building surveyors move into QS through contract administration and project management work. The other way is harder: experienced QSs on r/quantitysurveying say they'd know little more than a layperson about inspecting a building, and would expect to start near the bottom. Early on, building surveying employers do accept an accredited QS degree for graduate roles. The later you switch, the more of your APC experience you may need to rebuild.

Pay compared

Every source we've found puts quantity surveyors' pay level with or above building surveyors', and the gap tends to widen with seniority. How big the gap is depends on the source:

ONS figures for 2025: full-time quantity surveyors earned a median of £52,537. The closest figure for building surveyors is for all chartered surveyors, which includes valuers and others: £46,184.
Quantity surveyors by level (Prospects, from a 2026 recruiter survey): about £28,000 as a graduate, £55,000 once qualified, £70,000 at associate level, £85,000 as an associate director and £118,000 as a director.
Building surveyors by level (Prospects): £25,000 to £30,000 at junior level (up to £39,000 in London), £47,000 to £70,000 once qualified, and £80,000 to £120,000 or more at senior and director level.
National Careers Service: building surveyors £28,000 to £65,000, quantity surveyors £26,000 to £70,000.
What QSs say they earn. Salaries mentioned on r/quantitysurveying in 2024 to 2026 centre on about £30,000 for graduates, £37,000 for assistant QSs, £50,000 for QSs, £70,000 for senior QSs and £95,000 for commercial managers. Contractor-side figures are higher at most levels. These are figures people chose to share, not a survey.

Starting pay is similar, and the gap opens up with seniority, especially on the contractor side, where pay is higher but so are the hours.

For comparison, UK building surveyors' base salaries in this index so far: £47,500 typical (middle half £32,500 to £62,500), from 25 salaries. For pay by career stage and region, see the salary guide.
