Quick summary

Tendering involves asking at least five contractors for quotes to find the best one, ideally comparing three offers. You should have detailed plans and building regulation approval first, which helps contractors give accurate prices. Expect quotes to vary based on materials and project scope, with a focus on value and reliability over the lowest price.

Putting your project out for tender is when a homeowner looks to secure the services of a contractor.

It’s an important part of any project, whether that’s renovation, conversion, or extending. Get it right, and you’ll have a contractor that’s ideal for your home, and will help make your plans a reality.

To make sure you stay in the right lane, here’s our best tendering advice…

When to go out for tender

You can go out for tender as soon as you’ve settled on a design for your project.

That being said, we recommend waiting until you’ve sorted out your building regulations. That’s because, in order to gain building regulations approval, you need to supply your local authority with detailed drawings of your upcoming project, covering…

  • Structure
  • Fire safety
  • Groundwork
  • Soundproofing
  • Ventilation
  • Drainage

To name just a few!

With all these details in hand, your prospective contractors will be able to provide not only more accurate quotes, but they’ll also be able to build with confidence, knowing the ins and out of your project’s requirements.
