im worried it's going to require new pipework as the system is old and i've heard that old pipes can't always take the pressure of a new system. i've budgeted £6k for new boiler, pipework, radiators and labour, which i've been told is reasonable for a 2 bed flat (comments??). if the old pipes have to be dug out of the concrete and new ones put in and then concreted over, is it going to end up being really extortionate?

i would get several more estimates. that sounds a bit over the top for a two bedroomed flat.
ring british gas. i'm sure they could do the job for that money and give you some real good advice..
yes british gas do install central heating.

You don't want to be digging out the concrete. That would be way over the top adn you'd only want to do that if the flat was un-inhabited and free of all contents. Even then i'd question the need for it.
Pipes will only break with a sealed unit pressure if they are already faulty and corroded or with poor joints. Most systems run at 2 bar MAX and general copper pipe work can stand 4 bar minimum
You need to look at having boxed in pipes.
£6K with surface mounted pipes is too much.
microbore is ok but more noisy than 15mm and not as neat if any of the runs are exposed

If the ductwork is embedded in concrete, pressure shouldnt be a problem, I would think. If the pipes are rusted out anywhere they are exposed, you might have those replaced.
You're most likely to need to have the ductwork right at the central unit replaced, but the installer should do that as part of the work. For example, if the new furnace doesnt quite line up with the existing ductwork.. they would be responsible for any adjustments needed to make their unit fit.
It never hurts to get more estimates ... I like to always get 3 to 5 estimates, and check references. I rarely choose the lowest bidder, preferring instead to go with someone with the best references.
Good Luck

Forget the old pipework. Bear in mind that new pipework can be Microbore Plastic (to within 2ft of boiler) Its almost like Lego to put together, your main concern will be hiding the pipework, but in many cases it can be hidden in skirtings or if around the ceiling, behind coving. The quotes should be for a Combi Boiler.

These days they can use small bore piping with modern boilers which are easier to install and they can sometimes run the pipes in other ways with less reworking. I would recommend that you get 3 quotes at least and ask each of them how they are going to install the system. Start with the most reputable (say British Gas, Corgi Registered) and see the others compare. You may be surprised to find out that it works out a little cheaper than your estimate. Some are even offering free gas for a year with new installations.

Replace pipework, surface mount it in trunking, 6k is way too much, even the most expensive (British Gas) will not be much above that, what you need is a company who are approved by a boiler manufacturer ie Worcester Bosch or Vaillant, they will do a good job, issue a manufacturers guarantee up to 5 years (Worcester) and will still be under 6k.

I think it would be unusual for a reputable firm to install new central heating without renewing the pipework.
As has been mentioned, microbore piping could be used as this can easily be hidden (eg behind skirting boards) without digging up the concrete floor.
Get at least 3 reputable companies to give you a quote then make your decision

perplexing to assert with out seeing the equipment - yet interior the final public of circumstances the place there are "banging" pipes, it particularly is because of the pipes no longer been secured sufficient to partitions. you need to purchase a %. of 15mm or 22mm plastic pipe clips for bobbins, rule of thumb, clip it each and every 1m on horizontal runs, a million.5 vertical. yet, interest would desire to be directed around the radiator, as a prior poster says, if the radiator has moved (asserting 1mm of flow is undesirable is a "little" harsh, pipes can often take slightly of flow, a pair of cm right here and there) it would desire to be that it particularly is been moved too a approaches from its unique place and particularly some the pipes are somewhat flexed or bowed, so while the warmth comes via, the pipes multiplied placing tension on all of it. subsequent time it starts banging (while it particularly is heated) take out the pipe clips around the radiator, i may be stunned if this did no longer treatment it. Then replace the clips on the pipes to contemplate there "warm" place

1) 6K sound too much unless you have a massive house, get more qoutes. 2) DO NOT bury bare copper pipes in concrete.
