Before you accept a quotation, you should form a proper contract. Verbal agreements are difficult to enforce and aren’t recommended.
A simple contract could be signed acceptance of the quote, while a more detailed contract could detail conditions and clauses that are binding on both parties – including what happens when things go wrong (which we cover in more detail here).
It is normal for start and finish times to be detailed in the plumbing contract. You may want to stipulate what time they will arrive and leave, and that they should come every day until the job is complete.
If the work is inside your home, check whether you need to remove any furniture, carpets, or curtains. Check what safeguards the plumber will make to protect your home, and confirm that the plumber carries public liability insurance in the event of any damage. Every WaterSafe approved business is required to hold public liability cover of at least £2 million and employers’ liability insurance where appropriate.
Be sure to check what items are excluded from the contract, as well. Pipework boxing or re-decorating as a consequence of the work will often be excluded from the price.
Spell out payment arrangements clearly in the contract. Check whether a deposit is required and when final payment becomes due. It is always preferable to make payments in a phased way up to completion.
