How to price 'New Build' Plumbing/Heating work

[dreadnoughtheating]

This may seem an odd query from from one who considers himself an 'old hand' in the trade, but here goes.(mostly I do heating/boiler upgrades Unvented upgrades, servicing & boiler repairs, tap washers to bathrooms - all in existing structures..), but as my user name suggests - I will do it all!

Punter wants three quotes for 'first fix' plumbing/heating in a 'self-build'. Apparently the frame/outer skin is almost complete.

"I don't do new build", I did NOT tell him! But, where do I start?, as an old timer I believe that 'coppers proper', but that is so last century, I know it'll be Speedfit/Hep2o that will be thrown in by the others invited in to quote (and of course with no site security, copper is gonna disappear PDQ anyway.....)

I am hoping that the building suppliers (Potton?)will have specced up the heating requirements (tho' I am GasSafe reg with the required C&G in Dom htg)

I guess I would then be doing the poly water main, need a specification for laying that, water meter et-al. It can be tricky guessing where pipes need to come up for rad-valves etc, esp when other trades take liberties when laying that blasted T&G, glued and nailed chipboard flooring that adds so much to the structural integrity of the buildng.

So c'mon guys, can you spill the beans (so to speak) as to how you would price it. (Dayworks & Cost + perhaps?)

All assistance acknowledged.

When doing electrical work, I work out everything on a unit price for jobs like this, easy! However with other types of work I tend to try and calculate how long the job will take me in days, allow a day rate for that, if I will need a mate with me, his day rate is added on, then the material cost is added on, and then so you dont trip up I add on a percentage depending on how tricky things looked. As for rad tails, I would suggest bringing them up the wall and out about 2" above skirting level, if it is a timber frame I would put a noggin in with a tightish hole so it cant be moved about alot by other people, if it is a wet build then clip the hell out of the pipe so it cant be moved. As for the t&g, put that if the flooring damages your work you will have to charge to rectify and problems and you will only start rectifying the work once a price has been agreed on.

Hope this gives you a starting point to work from

Went for a dekko tonite.

'Kinell, its a four bedroom two bathroom jobbie, rainwater harvesting, wants AirSource heatpumps for the ufh, buffer tank for a 300 litre UVHWSS

No mains Gas....... walk? or stuff in a silly high price and hope I don't get it....

Hmm, breakfast meeting required with another company I 'sub-off' methinks

Waiting for a set of plans to send off to, say, UPONOR for an UFH specification.

Thanks guys, but keep'em coming

i did 3 houses once but was on day rate for a gypsy never again the gypsy not the houses!Most new houses are speedfit easy when you have done one all rads are connected with 10mm from a manifold.just put a back box behind where the rads going and leave tails sticking out and cap and test.Go around a show house you will see what i mean.
as for the ground source etc no idea might be worth post in combustion chamber and do the job with one of them guys most are decent.

If you're not sure how long it's gonna take etc. go for the silly high price and if you do get it at least you'll be able to do a proper job and not be left out of pocket. If you don't get it, never mind because you didn't spend too long working out the details and costs beforehand.
