"provisional" prices in a builders quote...

Sorry, this is a long one. I have loads rattling round in my head and am upset and frustrated by it all, so this will waffle!

We are towards the end of what should be a simple single storey extension to our 1920s semi. The old kitchen, which was in a lean to, was pulled down and we've extended across the back of the house.

We have a signed contract with our building firm with all sorts of clauses in it. It's their 'standard' contract. How much weight does this hold legally? Not that I'm getting into legal proceedings with them but I want to be informed when it comes to the discussion about money that will be happening soon. I'll explain.

When they initially came to give us a price, we were given an itemised quotation. There were a few things not listed that I queried and asked to be included and the price was amended. We have never changed the basis of what we asked for - the size of extension and internal work is exactly the same. So we instructed them, but I knew nothing about building work at all, I have two DC, one who was only 2 months old when the work started, I just wanted someone to competently manage the build with the tradespeople they had (on staff). Instead there have been delays, different 'site managers', lots of subcontractors and extra expenses. Honestly I'd have been better doing the whole thing myself!

Now we're almost at the end and the building company (who I'll moan about separately most likely!) are emailing saying "oh, the plastering is now going to be more than the provisional sum in your quote - we'll advise you how much in due course," and "your boiler fitting will be more than we quoted your for".

Can they do that?

I'm not daft, I've watched enough property telly to know that build projects almost always go over on cost and unexpected things happen! But I can't help the feeling that they're trying to shaft us with these changes to "provisional" sums.

We've already paid for extra skips, paid for some of the plumbing materials and due to their error, have not had the boiler where I wanted it (in the utility, it's now in the kitchen). I'm not against paying a fair price for the work we've had done but I feel like they deliberately under-quoted to get the job (not that they were the cheapest quote we had!). If the plastering was going to cost £1000 instead of the £750 in the job price, just say so, not change things.

Apologies for the rant. It's giving me sleepless nights (and with a bf little baby sleep is precious as it is!) and money worries. I don't know if we've been stupid, naive...urgh. I hate it. Whose idea was it to buy a 'project' anyway?!!!

Oh dear ! A quote is less flexible than an estimate - so are you sure they gave you a quote before ? If it says quote not estimate then they shouldn't be changing the pricing as they go along. Especially if the room of space hasn't changed .

Provisonal sums are used when it's hard to know exactly what works going to be done. For example when you don't know what's behind a wall/floor/ roof and not sure how much work its going to take.
Or if your not sure how much plastering is needed at the initial stages. They are quite common especially on refurbishment/renovation/extension jobs when you are working with the unknown quantities of an existing building.
Costs & day rates or job rates should be discussed and itemised so you can see what you are paying for when that provisional sum turns into a fixed cost.
I personally don't like builders own contracts and prefer to use industry standard ones such as JCT contracts although I've heard for simple jobs that the FMB one is quite good.
The reason I like industry standard ones are that they are written to cope with when things go wrong (which can make them a bit longer) and are fair to both the builder & the householder.
Contracts are only really there for when things go wrong so this makes sense.
It depends how it's written as to how useful it is.

If they are talking about provisional sums, they must have stated them as provisional at the beginning. If they were fixed quote sums and they are now referring to them as provisional then they are trying it on.
Go back and look at your paperwork carefully - as Houzz says check the wording, and check what it says about disagreements.
