Plumbing costs

[Nik2015]

Hoping that someone can give me an idea on the cost of putting in a new boiler, total replumb, replace existing radiators and move from under the windows to a more suitable area.
Its a 4 bed detached house.
Anyone had this done recently please?

Our new boiler, new pipes in boiler room (but not rest of house), hot water tank and 1 new radiator cost 6k last month

Lots of variables that will effect the price..
Where in the country are you?
What kind of boiler? Combi, heat only etc.
how many baths/ mixer showers?
How old is the existing boiler and pipework?
How many radiators?
What size?

One of the online next day boiler companies will give you a rough idea of price for that side of it in your area. The radiators is a bit more difficult to pin down.

NW near Manchester
Old boiler and pipe work is 1970s, so will remove this and relocate the new one.
A combi, probably Worcester combi boiler.
1 bathroom and 1 downstairs loo.

Very useful to know this thanks.

We had a new Worcester Bosch combi boiler installed recently, with new pipework, as installed it in a different location to the old boiler. 2 new radiators. Old immersion tank drained and removed, old pipework removed. In the South East, cost us £6.5k

If you're near Bolton no more than £4k .

@pudseypie all new pipe work throughout the house?

@almondflake I think we have the south Manchester premium applied!

Radiators can vary wildly in price too. Are you looking at bog standard white ones, or statement column ones? I would be tempted (once you’ve worked out what size you need) to buy them yourself. There’s a saving to be had there.

At that age you are most likely looking for a new pipe to the boiler anyway, larger size required today. Then it depends where your meter is and how difficult to put in a new pipe. We were quoted over £5 just for a boiler.

You ought to consider an air source heat pump. More expensive but more efficient. Underfloor heating instead of radiators.

@Nik2015 Probably, a lot of engineers won't travel out of Bolton due to the traffic which can add up to 2 hours on their day ,they'll go north towards Blackpool/ Preston way but not south .

That’s all. We’ve had a quote which is under 6k for boiler, radiators etc but defo need to clarify what’s included.

OP
Just take 3 like-for-like quotes inc VAT/etc and the same boiler/rads and warranty

NB: Ask the jokers if its going to be copper pipe all the way through as we had a joker called itself plumber and used some plastic pipes - i was disgusted but it was too late. as they'd done it and said nothing was wrong

We're getting a new combi boiler installed and relocated. Water tank and pump removed. 3.8k and the old boiler has just died so it's going to be a cold 3 weeks!

OP I've just been quoted over £4K for boiler and new rads in a 1 bed flat in London. Highly recommended friend of a friend, trust his pricing. He says Covid has affected manufacture and supply of some Chinese components so there's a 10% price hike over last year...

I'd say £6K for what you need sounds like good value but it's important to be sure of quality and specs of what you are getting.

Look on the plumb Centre website to get prices for the boiler and radiators, you then need to add labour, pipe work and the extras for fitting, but getting the base prices will help you see the different radiator options and boiler prices

I’ll definitely check out the spec he’s proposing. We’ve only got one quote as he’s a trusted local firm and we’ve not bought the house yet.
Am dreading moving into a new house and then doing all the work.

In London will be around 15K as floor boards will have to go up to relocate radiators, pipes replaced. New radiators I presume.Basically the whole replumb. Boiler alone is 1.5K, around 4K to replace/relocate.

@BusyEvenForBee wow about that price!!!

I know, happened to have a plumber in the house and just asked. They charge a fortune just to install the boiler. Cost of material went up significantly since Covid.

But it is London, should be cheaper in you area.

I've just this week paid £1600 to replace 7 old radiators for basic new white ones, including moving one a couple of meters, and flushing the system. This is in the East Midlands, and took a full day of 2 men.

We’re about to start renovating a 3 bed semi in South Manchester and we’ve been quoted just under £5k.

That’s a new boiler, replacing central heating pipe work where needed, replacing our gas pipes (lead and poorly placed), converting our open system onto closed, fitting new radiators and disconnecting two gas fires and some weird dangerous gas heater (can’t remember the name). They will have some floorboards up but we’re having a rewire so the electrician will be taking them up anyway.

Our quote doesn’t include our new radiators which I’m going to source, our heating engineer will check they’re right before I order though. I’m fussy and it’s cheaper to spend my evenings shopping around than pay the heating engineer to do it!

Am I missing something about the plastic pipe? I had some work done about 5 years ago and they used plastic pipe. But it was cheaper (they didn't charge me for copper!). It had a very good guarantee on it ...off top of my head, 25 years. Surely less likely to corrode....🤷‍♀️. Have I made a mistake?

I was also told by a plumber that having radiators under windows is the correct place for them. Something to do with how they circulate the warm air. I actually had one moved to be under the window for this very reason. So don't be too quick to move the position!

OP, my boiler with labour was around £1.5k a couple of years ago. But this was done on mates rates.

Nothing wrong with plastic, I re piped our whole house in plastic pipe
Far cheaper, less noisy, quicker to fit, less fittings needed. What's not to like?
