Get two or three quotes for the same scope, and check each one itemises labour, materials, and any extras like tiling or electrics separately rather than one lump sum.

As a benchmark, UK bathroom fitters currently charge £320-£480 a day, with total labour for a full refit typically £1,500-£3,000 depending on room size and how much plumbing/tiling/electrical work is involved (Checkatrade, 2026). If you're sourcing the suite yourself rather than having the fitter supply it, ask for a labour-only price — it's often cheaper.

Also check for a workmanship guarantee (usually 12 months), and be wary of vague pricing or pressure to decide on the spot.

I’d definitely ask for an itemised quote so you can see what you’re actually paying for, especially with labour, materials, tiling and electrics. A lump sum is fine too, as long as everything included is clearly explained.

It’s also worth asking about the guarantee and whether things like waste removal are covered. Have the quotes you received been quite different in price?

Chipping in from the plumbing side of these jobs. The labour-only vs supply question catches people out more than anything. If you source the suite yourself, check whether the fitter still covers call-backs for faulty goods, because plenty won't and you'll end up paying twice. Day rates down here in the South East run higher than the national figures mentioned above, but honestly the day rate matters less than the written scope. I'd want to see waste removal, making good, and who's doing the tiling and electrics all spelled out, plus pipework pressure tested before the walls get closed up. Lump sum is fine as long as the scope is nailed down. On guarantees, twelve months on workmanship is standard round here, separate from the manufacturer warranties on the suite itself. And I'd be wary of anyone asking for much more than a third up front.
