What Does a Site Manager Do? Duties, Tickets and Pay in the UK
What a UK construction site manager does each day, the safety duties and site tickets employers expect, how people get into the job, and what it pays at each level.
By Tony Musso on
A site manager runs a construction site from the ground up, day to day. They decide which trades are on site and in what order, make sure everyone works safely, check the work matches the drawings, deal with subcontractors and suppliers, and tell the project manager and client how the job is going. If something goes wrong on site, from a missed concrete pour to a near miss with a digger, the site manager is the person who sorts it out.
This guide explains what a site manager does in the UK, what a normal day looks like, the tickets and qualifications employers ask for, and what the job pays at each level.
What a site manager is responsible for
The job breaks down into five areas.
- Safety. On most projects the principal contractor must plan and manage the construction phase under the Construction (Design and Management) Regulations 2015, known as CDM 2015. On site, the site manager makes that real: inductions, permits to work, checking risk assessments and method statements (RAMS), and stopping work that is not safe.
- Programme. Sequencing the trades so the groundworkers, bricklayers, roofers, electricians and plumbers follow each other without waiting around, and spotting early when the programme is slipping.
- Quality. Checking work against drawings and specifications before it gets covered up, and making sure snags are fixed.
- People. Briefing the workforce, managing subcontractors, chasing deliveries and keeping neighbours and the public on side.
- Reporting. Keeping the site diary and records, chairing or attending progress meetings, and reporting delays, changes and cost issues to the project manager.
A day in the life of a site manager
Most site managers arrive before the trades, often around 7am, to walk the site and check that scaffolding, fencing and welfare facilities are in order. The first job is usually a morning briefing: who is working where, what deliveries are due, and any hazards for the day.
The rest of the morning is spent on site, checking progress and quality, answering questions from foremen and resolving clashes, such as two trades needing the same area. After lunch there may be a progress meeting with the project manager, a client visit or a call with the design team about a detail that does not work on site. The day often ends in the site cabin, updating the diary, reviewing RAMS for next week's work, ordering materials and planning the next day's sequence.
On a small housing site you might be the only manager. On a large commercial job you may run one section of the build, with assistant site managers and site engineers reporting to you.

Qualifications and site tickets
There is no single required qualification, but employers look for a mix of training and site experience. The common routes in are:
- A construction management degree, such as a BSc in Construction Management, often followed by a graduate scheme with a main contractor.
- The Level 6 Construction Site Management degree apprenticeship, where you work for a contractor and study for a degree, with no tuition fees to pay.
- Up from a trade. Many site managers start as a bricklayer, carpenter or electrician, become a supervisor or foreman, then take an HNC or HND in construction and an NVQ in construction site management.
The tickets that matter most are:
- SMSTS (Site Management Safety Training Scheme), the CITB course most contractors expect site managers to hold. It needs a refresher before it expires after five years.
- SSSTS (Site Supervisor Safety Training Scheme), the shorter supervisor course and a common first step.
- A CSCS card that matches your role. Many contractors expect site managers to hold the Black manager card, which is tied to management-level qualifications such as an NVQ Level 6 in construction site management.
- First aid and, on some sites, temporary works or fire marshal training.
Experienced site managers can work towards chartered membership of the Chartered Institute of Building (MCIOB), which many employers look for at senior level.
Who employs site managers
Large main contractors employ the most site managers, but they also work for housebuilders, specialist contractors, fit-out firms, local authorities and infrastructure clients such as National Highways and Network Rail. Smaller builders often combine the site manager and project manager roles. Housebuilding sites tend to suit people who want to stay local, while big infrastructure projects can mean working away from home during the week.
How site managers progress
A typical path is assistant site manager, then site manager, senior site manager and either construction manager or project manager. Some move into contracts management or operations director roles; others become clerks of works or move to the client side. If you are drawn to the planning and budget side more than running the site, read our guide on how to become a project manager.
Is site management for you?
The job suits people who are organised, decisive and comfortable being the one everyone comes to with a problem. Expect early starts, time outside in all weathers and days when the programme, the client and the subcontractors all want something different. You also carry real legal responsibility for safety, so you need to be firm when a gang cuts corners.
Three ways to test it before you commit:
- Ask a local contractor whether you can shadow an assistant site manager for a few days, including a morning briefing.
- Take the two-day SSSTS course to see whether the safety and legal side interests you.
- Talk to a foreman who has moved into management about what changed in their week.
If you are not sure whether construction management suits your strengths, the Career Compass assessment compares your interests and priorities with careers like this one.
Mistakes that hold people back
- Relying on a safety ticket alone. SMSTS shows you understand the law, but employers want proof you have actually coordinated trades. Supervising a small package of work gives you that evidence.
- Holding the wrong CSCS card. Card types are tied to specific qualifications. Check the CSCS website to see which card your target jobs need, then plan your NVQ to reach it.
- Letting SMSTS or SSSTS lapse. An expired ticket can keep you off site. Note the expiry date and book the refresher early.
- Underestimating the paperwork. RAMS, permits, the site diary and quality records take up a big part of the week. Show employers you keep accurate records, not just that you can run a gang.
- Skipping the assistant role. Jumping straight from a trade or university into running a site often goes badly. A spell as an assistant site manager or site engineer teaches you programmes, sequencing and how to handle the client.
When you apply, put your tickets near the top of your CV and give each project's type, value and number of trades. Our CV builder helps you lay this out.
