Project management questions for builders

A building project, whether it is a kitchen extension or a full renovation, can quickly become complicated. The way your project is managed day to day affects how well trades work together, how problems are handled, and how much hassle lands on your shoulders. Knowing who is actually in charge on site, and what to expect from project management, helps you avoid confusion, delays and costly mistakes.

Main contractor or managing trades: what does it mean for you?

The first decision is whether to hire a main contractor or to contract each trade directly yourself. The difference has a big impact on who is responsible for organising the work and sorting out issues as they arise.

• Main contractor: This company or sole trader takes charge of the full project, including hiring and managing subcontractors (such as electricians, plumbers, plasterers) under one contract with you. If a problem crops up between trades, the main contractor sorts it out. You deal with one point of contact, and they are responsible for coordinating the schedule, quality and site safety. If something goes wrong, your contract is with the main contractor, so you do not have to chase individual trades.
• Managing trades yourself: Here, you hire each trade directly and hold separate contracts with each one. You are responsible for organising timings, making sure one trade finishes before the next starts, and dealing with any disputes or overlaps. If the plasterer cannot finish because the electrician is late, you are the one who has to sort it out. This approach can save on the main contractor’s fee, but it means you take on the project management role yourself, with the time and risk that brings.

Either way, under the Consumer Rights Act 2015, each contractor or trade must do their job with reasonable care and skill, in a reasonable time, and for a reasonable price if nothing was agreed upfront. But how smoothly the project runs depends a lot on who is actually managing it day to day. You can compare builders on Annuvell Local to see who offers main contractor services and what facts are published about their business.

Key questions about site management

Whether you use a main contractor or manage each trade, ask clear questions about who will be in charge on site and how the job will be run. The answers help you spot gaps before work starts.

• Who is the site manager or main contact? Ask for the name and contact details of the person who will be there regularly and in charge. If the owner or lead builder will not be on site daily, who has the authority to make decisions? A clear answer shows the business has thought about management.
• How is the work programme planned? Ask to see a rough schedule or programme of works. It should show the order of trades (such as groundworks, bricklaying, first fix electrics), how long each stage is expected to take, and any key deadlines. A builder who can talk you through this has usually done similar jobs before.
• How are trades coordinated? If there are several subcontractors, who makes sure they do not overlap or delay each other? Ask how handovers between trades are managed. For example, when does the electrician come in, and who checks that everything is ready for them?
• When are building control inspections booked? Most notifiable building work must be inspected at set stages (such as foundations, drainage, structure, electrics). The builder should know when these are due and who books them. If you are managing trades, you will need to arrange these yourself.
• Who is responsible for sign-offs and certificates? For jobs like electrical rewiring, you will need certificates for your records or to sell the house later. Check who supplies these, and when.

How decisions and changes are recorded

Changes are almost inevitable on a building project—unplanned discoveries, material choices, or simple design tweaks. How these are handled says a lot about project management.

• How are changes agreed and recorded? Ask whether changes must be put in writing (such as by email or on a change order form) before any extra work starts. A clear process avoids disputes later about what was agreed or what it will cost.
• How often will you meet or check in? Regular meetings (even a ten-minute catch-up on site each week) help spot issues early. Ask how updates will be given—face to face, phone, or email—and how often you will be expected on site to make decisions.
• How are snagging items tracked? At the end of the job, there will almost always be a list of things to finish or fix (the snagging list). Ask when this will be done, who will check it, and how you can record anything you spot yourself.
• What does handover look like? When the builder says the job is finished, what happens next? Check whether you will get a walk-through, a set of certificates, or a final written sign-off. This is also the time to check guarantees and make sure you are happy before making final payments.

What project management costs you in time if you do it yourself

Taking on the project manager role yourself can seem tempting, especially if you already know some local trades or want to save on main contractor fees. But the job involves much more than making phone calls and paying invoices.

• Chasing trades: You will need to track when each trade is needed, confirm dates, and chase up delays. If one job overruns, the knock-on effect can mean rebooking others at short notice.
• Ordering materials and inspections: Arranging deliveries, checking what is needed for each stage, and making sure building control visits are booked at the right times all fall to you. Missing an inspection can mean having to redo work.
• Sorting out disputes: If the plumber and electrician disagree about who should do what, you are the one expected to resolve it. Any errors or gaps between trades may not be noticed until a later stage.
• Dealing with paperwork: You will need to keep records of quotes, invoices, certificates, and changes. Without a clear system, it is easy to lose track of who agreed what.
• Being available: Trades may need you on site with little notice for decisions or to unlock the property. You may find you need to take time off work or rearrange your own schedule around the build.

Unless you have previous experience or plenty of time, running a project yourself is a significant commitment. Many people choose a main contractor for this reason.

What to look for on a reference visit

Visiting a previous project—ideally while the job is still fresh in the client’s mind—can tell you a lot about a builder’s approach to management. Here are some signs of a well-managed job:

• Clean and organised site: Materials are stacked tidily, walkways are clear, and there is little waste left lying around. This suggests the trades are coordinated and safety is taken seriously.
• Clear evidence of schedules: Look for a copy of the programme of works on display, or ask the client if they were kept up to date on timings and milestones.
• Visible sign-off points: Ask the previous client how the builder handled building control visits and whether certificates were provided promptly. A well-managed job usually means all paperwork is in order.
• Snagging handled efficiently: Find out if snagging items (minor faults or finishes) were sorted out quickly and with minimal chasing. Delays or disputes at this stage can be a red flag.
• Client kept informed: The client should be able to describe regular updates, clear explanations of changes, and a single point of contact throughout.

Next steps

Write down what you want done and whether you want a single main contractor or to manage trades yourself. When you speak to builders, ask who will be responsible for the day-to-day running of the job, how they coordinate trades, and how changes are recorded. Request quotes from a few builders near you, and use the compare tool to see how their answers on project management stack up.
