How much does central heating and plumbing cost on a new build?

CharlemagneJ

Trying to determine hoe much I need in a mortgage. Can anyone give me a rough idea how much plumbing and central heating costs in a new build? I would need the following;

 7 Radiators.
 1 Shower.
 1 Toilet.
 Natural gas heating system.
 Waste treatment or septic tank.

The build would be a bungalow in the midlands, just if that makes any difference.

It's hard to give a cost on this without details, requirements, spec etc. But I would imagine you would need approx 15k Euro. This would include 5-6k for solar and 300ltr cylinder for hot water, gas condensing boiler, labour and materials for all hot and cold feeds to all sinks, showers, kitchen, toilet etc. Radiators, attic storage etc.

Toilet could cost in the region of 150 - 450euro, Shower tray depending on size would cost between 120 - 300euro, shower doors about be about 175 - 400euro again depending on size, style and spec will increase these. The shower mixing unit and controls approx 250euro upwards.

Get brochures from different suppliers in your area and then see what you like and ask for costs.

Not sure on waste septic tank but possibly another 5k

So Delfagio, you would estimate that plumbing and central heating (basic spec) in a bungalow (~ €100,000 budget) would cost close to €20,000? Is that correct? That would be a huge portion of the budget!

It is part of the Part L compliance.
Judging by your other post about pricing a roof, it sounds like you haven't got construction details or costsings done yet. If you have €100k budget, how big do you think the house will be?

Council contributions
Power connections
Water/waste

Are these to come out of the 100k also?

Yep, thats correct. I've not talked to anyone as of yet. I am just trying to get information. There are quite a few €100,000 houses in my locality. I am looking into building a bungalow for €100,000 instead. I have a site already though. I would be able to get the foundation and block work done for around €12,000 to €15,000 to. So I am trying to get rough prices on on a roof and the plumbing/central heating. Its in the countryside so water will be sourced from our well.

how big do you want this house? 2 rooms and a kitchen and 1 bathroom?

House is 180m2 bungalow.

100k will fall a long way short. 100k will get you to plastered outside. Perhaps first fix plumb and electrical also (second fox is where the €€€€ will disappear).

Thanks for the advice. Just in relation to plumbing and natural gas central heating. Any input on how much that might cost on a new build?

So it would seem that buying a 2 story house for €120,000 (very possible here) is a way better option than building a bungalow on a 1 acre site that you already own? That seems crazy.

Nope much cheaper. Budget €110-115 for builders finsh excluding design and contributions.

Average cost of the Mechanical for a house these days is 15k excluding ware. €10-12k for Electrical.

Thanks to those replying.

Ok, have a look at this list that I have made and let me know if any costs seem way off or anything significant is missing.

Rectangle Bungalow (50ft by 30ft). Open Gable style roof.

o Plans and planning ~ €5,000.
o Foundations and blockwork ~ €20,000.
o Roof ~ €25,000
o Water ~ €3,000.
o Plumbing, waste and natural gas central heating ~ €18,000.
o Electrician ~ €4,000.
o Insulation and plastering ~ €10,000.
o Flooring and tiling ~ €8,000.
o Fixtures and Finish ~ €10,000.
o Miscellaneous costs ~ €9,000.

Without a preliminary DEAP report, those figures could relate to nothing.

You need a prelim DEAP report to assess how your going to build and how your going to comply with regs (particularly part L)

So are you saying there is no roughly generalisable way to estimate the costs involved in completing the basic aspects of a new build?

The spec of the house you build will most likely be light years ahead of buying a 100k property in the area

What about landscaping, boundary walls, VAT? Is your waste to a public sewer if its a tank and percolation area thats 6k min on its own. I am assuming you will be heavily involved in providing your own labour in those prices?

youre pretty specific with your opening post.

insulation and plastering in that calculation is probably another 100% on top in reality.....

To be fair these are miles off and I am a Chartered Surveyor. I don't know where they got some of these prices from.

Thanks for the list on the other thread BTW.

There is a wire fence around the site and that can stay there for a few years and as far as landscaping, short of putting a few tonnes of chippings in as a drive, there wont be any for a few years either. I had included the waste treatment in the €18,000 for plumbing and central heating, is that not enough? I am hoping to build slowly. I would labour for a good block layer and I have family who lay the foundation while I labour. I'll paint and lay floors myself. Litterally, anything I can do I will do. I just want four walls, a few rooms and a roof in the middle of a patch of grass with water, elec and heating. I'll wait a few years before I try and make her lovely looking.

Literally got all of them prices from other threads here. As I said in the other reply though, I would be laboring intensively and managing the build myself. No contractor. Just hire good tradesmen as each job comes up.

I get where you are coming from and if you are able to do alot by yourself you will save a packet, but you must remember you need to build to the current regulations and they require some oversight than a few lads helping you because there is alot of joined up thinking required. If you got the documents setup right at the start with alot of detailed information then you will be off to a good start.

Keep everything as an off the shelf size, nothing curved and you should reduce your outlay, but it will be one boring house.

Also, just remember whether you put the money in now, or down the line, the money still has to go into it so your fooling yourself by talking about doing things down the line.

Metric Tensor

Absolutely no point doing a breakdown of costs until the house is further designed OP. You're just wasting your time.

Budget an absolute minimum of E110** per square foot. So for 30 X 50 that's 165k. If you don't have that much money you will be wasting what you spend on the planning.

**That's assuming you get substantially reduced rates and your bank will be happy with you moving into an incomplete house.

Getting breakdowns of individual elements is not possible to any useful extent without at least a partially developed set of plans and a DEAP calculation to show how much insulation, solar panels, etc you require. You have none of that yet. Stick with a rough cost per square foot for now.

P.S. You will buy a house for much cheaper than you will build one because materials, labour, building regulations, etc are all going the same way.

OP you seam to be looking for one randomer on the Internet to say this is possible to build @€;100K to justify your taught process. Several here who have experience in the industry have told you that you don't have a hope, take their advise. Also I am not trying to be smart here, but you clearly have no experience in the building industry, what makes you think you will be able to do this project substantially cheaper than the professionals cost price? How much of a margin do you think builders of one off houses actually have?

delfagio

Yes id would say it's in the correct ballpark, that's including Solar with 300ltr cylinder, gas boiler, all internal Plumbing for labour and materials and waste septic tank.

How many bathrooms do you have??

I would image you are falling good bit short on some items here.....what size house are you building?


Blockwork and foundations - 20k seems very low. I'd say for your foundations and sub floor will cost closer to 25-30k alone, this would include labour and materials for topsoil strip, excavations for foundations, steel mesh, concrete, dead blockwork, hardcore backfill, compaction, blinding, radon barrier, steel mesh, concrete subfloor.
Blockwork for the house itself I would imagine to be possibly another 25k including all labour and materials.

Electrical - for labour and materials I'd image closer to 10,000, again depending on spec but allow for future proofing the house, I wouldn't just do basic as its easier to do additional cabling for CAT6, extra sockets, led spot lights, etc now than later when it's all covered over.

Insulation and Plastering - for labour and materials I would say closer to 15,000 - 20,000. Insulation will be a big cost for the house to bring it to Part L compliance. Underfloor insulation, attic insulation, wall Insulation, etc. Insulation costs are always going up these days.
Plastering alone for approx 2500sq foot bungalow would be 10,000 minimum. I'm assuming it is block built house with block walls internally, therefore to scud, scratch coat, skim etc will take a lot of materials and labour so I'd say 10 - 12k for this alone. Have you allowed plasterboard for ceilings?

Hope this helps a bit
