Quick summary

When choosing contractors, always get at least three references and review recent work to ensure quality. Expect to pay more with larger firms or fully established companies, which can cost more but offer better reliability and faster completion, often within a few months. Smaller trades or solo builders are cheaper but slower and riskier for finance and timing.

Contractors come in all shapes and sizes, each with their own individual specialities and experience. Choosing the right one for your project will ensure you not only get a quality build but that your budget remains in good hands during construction.

Types of contractors

When you start the tendering process, here is a list of key contractor terms you’re likely to encounter.

Approved contractor

This is the builder you have appointed to carry out work for your project. They’ll be selected during the tendering stage based on their level of experience, resources, and track record.

Construction manager

Your construction manager won’t be carrying out the work themselves, it’s their job to manage the trade contractors who are onsite.

Design and build contractor

These types of contractors not only provide the build, they also handle the architectural design too. Unlike architects, they won’t have any formal design qualifications and you won’t have the same level of protection on this front either.

Domestic subcontractor

Selected by your main builder, a subcontractor will be brought onsite to carry out a specific part of the construction works. Because you won’t be part of the hiring process, it’s worth discussing if your builder plans on using subcontractors during the tendering stage.

Nominated subcontractor

This is a subcontractor that you have selected and imposed on your main contractor to work with.

Named subcontractor

A homeowner might choose to put together a list of subcontractors for their main contractor to select from. Because they’re making the final selection, the responsibility of this subcontractor will fall to your main builder.

Supplier

A general term that’s used to describe any provider of services or goods during the construction process.

Trades contractor

A contractor who is in charge of a specific element of your project, such as the electrical installation. Unlike a subcontractor, this is a professional you have hired directly and manage.

Work package contractor

This specialist contractor handles specific aspects of the maintenance or replacement work a build might require.
