What type of system? Under screed?
Floor panels? Clipped down?

600 metre square is 360,000 square metres - so hopefully you meant 600 square metres!?! 🙂

Bit hard to give advice from your post.

How many manifolds?
Boiler: How many?
System controls?
Manifold mains back to boiler?

Rough estimate - 30 circuits & 80+ kW boiler.

It's not the laying of coils that's the issue, it's the design of the layout, running mains back to boiler, the controls, the electrics, the boiler installation, the boiler configuration / setup.

Jobs that size are generally not a 'turn key' job. You will be back stuffing around with with things after completion.

For all of you:
1 day for marking out.
3 days for laying coils.
2 days for mains.
1 day for manifold installation.
1 day for testing.

Plus days for boiler installation, control wiring, thermostat setup, flueing, commissioning & probably 16 hours on the job for aftercare / ancilliary's after completion of installation.

Vague - I know, but hope it helps

Speedfit will design and give you material list for underfloor.
You've already said 2 weeks for 2 plus one.

Work out your labour then add to it your materials plus %

Two gotcha's that may or may not be applicable in your circumstances:

1. Keep in mind that if, your bread and butter is domestic work, by taking on a large commercial project you may have to have to turn away new customers and disappoint old ones while you're tied up. They're going to find someone else and you'll need to find replacements.

2. Check the contract carefully for what happens, for example, if you get ill and can't complete the work on time. Some contracts are very risky if you don't have a big enough team to handle contingencies.
