Fair Price For A Quality Job Here??

[cr0ft]

Just finished designing the CH system I spoke about before. The house is 520 square metres of floor space over 4 floors. Total heat loss is pretty much bang on 70KW from calculating it so 2x 35KW boilers. 32 radiators. Just around 500sq.m of the house will be heated so 5 heating zones and of course HW too, unvented cylinder.

Am hoping to run the two boilers on reverse return into a low loss header then run hot water flow and return plus suitably sized heating primary from low loss header. Zone valves as the heating rises to each floor. One large pump to deal with the head height of about 10m.

House is around 200 years old I believe. High ceilings on the 2 middle floors, 4 and 3.5m high respectively. All work needs to be done as sympathetically as possible to the building as it's grade 2 listed.

All I've ever priced is normal domestic houses! Happy with designing this and pricing the materials up but how long should I allow for this? The house is around 15x12m and new pipework will most likely need to be surface run in corners of rooms to rads, chasing into walls is not going to be an option here. Decorative mouldings in all rooms to do nice bends around too!!

Don't want to price myself out of the market but this is a big job and don't want to work for nothing either. Also need to run hot water pipework from the cylinder on the ground floor up two floors to the bathrooms around 15 metres run for each (next to each other).

If anyone could give me prices for labour for comparable systems they might have installed that would be great.

We done a old listed hotel in North Devon few years ago build control involved rolled into a right drag as they sucked up unforseen time

I would be looking 5k labour minimum.

These type of houses take twice as long as a normal house. So don't think just because there is 3 times the rads, so it will take three times longer.
Pipe runs are more difficult and longer. Pipe size is larger and more difficult to thread in.
I would say you would need to account for labour at your rates as below
Plant room 4 days
Strip out and making good 2 - 3 days
Heating 10 days
Allow another 10 % for unforeseen difficulties.

That's about 19 days.
Font sell yourself short. Your not a charity! It will be good for experience, but could be a nightmare if you lose a fortune.

Price high.
Leave with a smile on your face.

Just wondering what size gas meter have they got ?

 

[stevetheplumber]

normal meter will not feed those 2 boilers but there was a 70kw there before so would assume is a 16

i would be looking at 8k labour minimum they will struggle to find many one man bands willing to take it on so will be looking at bigger companies who will be well over that how much work you doing after the cylinder or is someone else doing bathrooms?

It's a U16 meter. The gas pipe run is JUST within the limits of what us domestic engineers are allowed to install as the meter is right next to where the boilers are going.

We have been asked to quote for a wetroom install and a bathroom too. I think they have had one man companies out already who have all left in a hurry.

TBH it's one of those jobs that I can see eating up more time than we expect and so I'm going to price it at £10K + VAT labour having reflected overnight. Materials on top with the usual markup of course. I don't think we will be competing against one man companies on this one and I think a lot of people will do a runner as it's a listed building. I'm either mad or I like a challenge.

Drive yourself mad with a challenge.

Break the job down into sections and price per section.

32 rads x how long each rad will take to install.
For pricing - I would allow an hour per rad,

...and so on.

Larger jobs can get away from you if you don't have the experience in quoting them.
So take the time and go through each section of the job and price accordingly.

Don't just take a stab at what you think will be a fair and competitive price for labour - you will lose out more often than not
