Hi all, boiler is not firing and can't be repaired. Am I being completely unreasonable in my expectations. Quotes are all around the £5k to £6k mark. I thought it would be nearer £3K. Current system is an old glowworm boiler with microbore piping located in the kitchen. Lowest quote follows:
To install a new combi boiler located in the loft with new pipework to the radiators it going to cost all in £5300.

If you want all new radiators it will cost any extra £800 this includes new radiator valves. ( I don't think there will much making good to do around them)

I can come in a start on Monday 20th of January aiming to be done by the end of the week on Saturday/ Sunday

This price includes the rip out and removal of the old system, getting a electrician to come and do the wiring. And a full commission and registration at the end of the job.

Please don't hesitate to ask me any question.

Do these sort of figures sound reasonable? It's a three bed semi.

No.!! £3k Maximum.
If it is installation and new boiler plus labour then about 5K. But the boiler alone is around 3K.
Only if you go with British Gas,Sharon,go to an independent Heating Engineer,that's all BG do,called Sub-Contracting.

Wow one yes and one no so far. This is from an independent contractor, an ex SSE employee. I was expecting about £3k into £4k with new radiators. This quote is almost £6.5k.
Sounds like there's a 'fear of being cold in winter' loading on the quote.

I'd get another few tradesmen in for a look around.
Which boiler and what output?....plastic or copper pipes? many years warranty? how many and rad type/size? what type of or conventional?Where are you?
Jeeeeez - what kind of boiler are you getting??
We got a "Main Combi Eco" about 5 years ago. The boiler itself was less than £1k and the plumber charged £250 to fit it. It was virtually a straight swap for the existing boiler, just a bit of tweaking needed with the existing pipework - nothing too major.

I can understand your quote being a lot more than mine, if you're having to have all new pipework, but your quote does seem a bit excessive to me. Is it really necessary to change all the pipework??
Would it work out cheaper if you have the boiler put in your kitchen instead of your loft? Why do you want it in your loft?

Thanks everyone.
I'm in Oxfordshire, three bed semi. More info from engineer here....""My quote it for the boiler relocation, new gas main to the boiler, removing the hot water tank and old boiler, running new heating pipe work in the floors to the radiators ( dropping down the wall to the bathroom and downstairs hall radiators), all new radiators I believe there is 10 ( 6 downstairs 4 upstairs) with new trv valves. And the installation ation of the new boiler""

Existing pipework is the old mini microbore so needs upgrading to 15mm copper. It could potentially go in the same location but not without a considerable damage to your kitchen surfaces tiles and cupboards. It's not in a practical place currently. Also the quote are from independent engineers, haven't tried Any firms yet as I assumed they'd be even higher
I would get at least another 2 quotes.
With all the work involved i.e the relocation of your boiler, it's understandable it will cost a lot more than a straight forward swap.Still, with a job like this it's always worth getting more quotes and checking that the installer has the necessary qualifications. At one time it used to be Corgi registered but it's a long time since I had mine done so this might have changed.
With great respect to other, horrified, posters above, I think many are missing the point.

Direct boiler replacement is one thing, but this is completely different.
Pipework and electrical replacement is horrendously disruptive, thus time-consuming and costly.

Add to this... the probability of fitting a new flue, removing old equipment and making good, dealing with furniture/carpets/skirting boards/floorboards or chipboard etc etc....

I must tell you, in all honesty, Ruggie, that only John Wayne would take all that on for 3K.

I see you have other quotes. Really, 5.3K would seem about right to me for a decent job.
Yep, 5/6k will be about right, plus its a bit like buying a caravan in the summer. ;0) defo go for the new rads.
Considering your reply and location...I recon £6k all in inc vat...for that you would have top spec 40kw boiler with stainless heat exchanger and a 12 yr warranty..quality rads with 15 yr warranty.. smart control and associated access boards etc as required for loft installs.
..if the rads are not too big you could have a smaller boiler with a few hundred pound saving.
The Builder , I understand the size and extent of the changes being made, but for that kind of expenditure personally I would always advise 3 quotes
find a local plumber, repair what you have in place, if it not leaking gas
at least, try a repair, was it condemed? if not your getting shafted.
Fender. I don't agree he is being shafted, do some sums on the required materials for a start. To kick off with, a decent boiler, with decent output, your not going to get much change out of £1000, the flue is extra, radiators £700/800, copper piping is expensive, plus a lot of copper fitting, price the radiator valves up x 10, thermostats, the list go's on with bits and dabs that both the electrician and boiler engineer will use to install such. You then have the labour, and with a job like this there's a lot. Floor boards have to be cut in various places, and taken up, old piping removed, joists cut out for new piping, ceilings drilled out, even positioning and hanging 10 radiators is a big job in its self, again the list of labour go's on. Your also employing two skilled people, and their not going to work for £50 per day, plus either one of them may have a labourer. :0)
