phill.p Posted February 27, 2012 Report Share Posted February 27, 2012 As per the title. The wife has a guy coming around tomorrow to give a quote to fit a new gas boiler. Open vented Intergas type. Does any one know what the expected cost might be. Just so she has an idea. The boiler has already been bought, so just the price of fitting. Im working away and she is a bit worried about getting ripped off. Phill Quote Link to comment Share on other sites More sharing options...
harrycatcat1 Posted February 27, 2012 Report Share Posted February 27, 2012 I havent a clue how much mate but I would want more than one quote, just so I could see if they were all similar. Good luck with it anyway. Quote Link to comment Share on other sites More sharing options...
buckaroo23 Posted February 27, 2012 Report Share Posted February 27, 2012 I had a quote for a new boiler new thermostat and a wireless thermostat £2100 this was for a gas boiler Quote Link to comment Share on other sites More sharing options...
bear-uk Posted February 27, 2012 Report Share Posted February 27, 2012 Depends on how much time to fit. Just had a combi fitted and took 2 days. Would have been around £700 for labor and fittings. Quote Link to comment Share on other sites More sharing options...
Asa Bear Posted February 27, 2012 Report Share Posted February 27, 2012 Depends on many things. Such as is gas supply sufficient and are thermostatic valves fitted throughout. As has been previously stated get at least three quotes from gas safe registered companies preferably from recommendations. Quote Link to comment Share on other sites More sharing options...
dazsl Posted February 28, 2012 Report Share Posted February 28, 2012 average price to supply and fit a boiler in same place as old boiler £1300 so take the price of your boiler off that Quote Link to comment Share on other sites More sharing options...
Tim Kelly Posted February 28, 2012 Report Share Posted February 28, 2012 You'll almost certainly need to have the DHW cylinder changed, thermostatic rad valves fitted, and strictly speaking a separate heating zone designed in for the first floor. That is all to comply with Part Lb of the building regs. Definitely make sure they fit a "magnaclean" type filter to the heating system. The gas supply may well have to be upgraded too, and the system must be power flushed. You won't see much change out of £2500 in my opinion for the job to be done properly.

I can understand the power flush, the possible upgrade to the gas and the magna clean (not essential though) but why the hell a new cylinder he is only changing the boiler like for like, as for the seperate heating zone, rubbish.whats wrong with the system as it is he is only wanting a boiler replacement Quote Link to comment Share on other sites More sharing options...
Cosd Posted February 28, 2012 Report Share Posted February 28, 2012 (edited) I just had this done for my parents, theirs was simply taking the old combi down off the wall, and replacing with the new boiler, and adding thermostatic valves on all the radiators round the house. Labour only (but included flushing liguids) £550 and done in a day by one man. Edited February 28, 2012 by Cosd Quote Link to comment Share on other sites More sharing options...
Pedro Posted February 28, 2012 Report Share Posted February 28, 2012 We've been quoted £3200 for a new gas combi, but that's completely changing where the boiler is, fitting a new flue, thermostats etc etc. The old one's developed a chuffin leak, but has been going for around 20yrs so its not done too badly P.

Sandbank Posted February 28, 2012 Report Share Posted February 28, 2012 Paid £2700 for a brand new installation (no previous rads, pipes, boiler etc.) for a 3 bedroom semi I have bought to rent out. Labour costs were quoted as £520. For a replacement system should be less unless you have a 12 bedroom mansion. Quote Link to comment Share on other sites More sharing options...
super sharp shooter Posted February 28, 2012 Report Share Posted February 28, 2012 I hade a quote from British gas for a combi boiler replacement. £3200 Quote Link to comment Share on other sites More sharing options...
phill.p Posted February 28, 2012 Author Report Share Posted February 28, 2012 Thanks for the input guys. It is just a like for like change. I intend fitting a Magnaclean and it could do with flushing, which I know should be done before the new one goes in. But I was planning on doing those jobs myself, along with a bigger cylinder that came courtesy of the mother inlaw when she had a combi fitted.

ferguson_tom Posted February 28, 2012 Report Share Posted February 28, 2012 even after British gases amazing £400 off deal? Which still makes them a lot more expensive than any other installer. I was quoted 2k for a boiler replacement, which i thought was a bit steep to be honest for the amount of work involved. I know they got to make a living but it was only a days work and i was flushing the system. I did have one bloke who said he would come turn off and disconnect the gas, let me install the boiler i would buy and do all the plumbing and he would come back connect the gas and commission the system for about £250. We ended up just paying for the old one to be fixed. Quote Link to comment Share on other sites More sharing options...
harpoonlouis Posted February 28, 2012 Report Share Posted February 28, 2012 Just wrote a cheque to pay for a Main Baxi HE boiler that went into a rented out property, £680 for the boiler, £240 labour to fit it. Quote Link to comment Share on other sites More sharing options...

Asa Bear Posted February 28, 2012 Report Share Posted February 28, 2012 (edited) To comply with building regs you only need to upgrade system controls. If the system is gravity HW it will have to be converted to fully pumped. You'll have to fit a cylinder stat but not necessarily replace the cylinder.

So what are you going to change the DHW cylinder for, another DHW cylinder by any chance ? Quote Link to comment Share on other sites More sharing options...
Tim Kelly Posted February 28, 2012 Report Share Posted February 28, 2012 Yes, a part L compliant one. Don't shoot the messenger. I didn't make the rules up! The guys who are swapping the boilers for £200 are clearly not doing the job properly. Buying cheap boilers then getting them installed by monkeys is going to be a recipe for a short boiler life and a load of grief getting it repaired. Modern condensing boilers need to be installed properly, with good powerflushing and a magnaclean filter to give them a chance of a long life. The heat exchangers are much finer than older boilers, so will easily get clogged up by the **** in the system from a poor installation.

-Mongrel- Posted February 28, 2012 Report Share Posted February 28, 2012 Because that's the law! For a boiler to be signed off legally the whole installation needs to comply with part Lb of the building regs. ******** mate. If it's a new installation then yes, you need to comply with much of what you are saying although the upstairs zone is only if you have more than 150 sq metres floor area. Existing systems must have TRV's on the bedroom rads, full controls (room/cylinder 'stat as required, timer if required and control valves if required) and a boiler interlock. That's it. Flushing is a manufacturers requirement not Building control but has to be done anyway as an installation requirement. The installer will need to flush/inhibit it before he can sign it off and if it's not signed off it can affect the warranty validity, personally I'd suggest you let the installer do it as part of the install.

Not all systems need to be powerflushed though which is why the manufacturers Benchmark only asks if the system was flushed, in a clean system then a standard chemical clean and flush is plenty.

daz2202 Posted February 28, 2012 Report Share Posted February 28, 2012 Totally agree, anyone changing a boiler for £200 is either very desperate for some quick cash or not really carrying out there dutys as a gas safe installer. Around here a combi for combi change with minimum pipe work changes, labour would be around £500 Open vent to combi with bit of a system update would be around £900 labour Gas safe registration and all the other **** that we have to pay for is very expensive so although it looks a lot but so is a heating engineers costs like as of end of this month everyone must have done another exam to prove we can use an analyser for the flue gases that we have been using for years .£300 for exam 1 day off work & £270 to calibrate a perfectly fine analyser.

Tim Kelly Posted February 28, 2012 Report Share Posted February 28, 2012 I've got to re-do my gas course, starting this Thursday. £1100 plus five days of not earning, even then I still need to re-do my unvented, as they decided it was no longer a lifetime qualification and something else I can't remember, so that will be another few hundred quid. Didn't realise the 150m3 part of the regs, but even so, my tiny 2 up one down house looks like it's about 100m3, so it wouldn't have to be much of a house to make 150m3. There aren't many boiler systems which are clean enough to install a new boiler without power flushing. I can think of maybe two in the last few years when I've thought I could get away without! TRVs have to be on all rads except those in a room controlled by a stat, or bathrooms. Virtually all cylinders will need to be replaced as the part l standard is only about 5 years old, so unless someone's had a new cylinder fitted very recently, it will need changing.

Sorry mate, no they don't. 'Best practice' requires that, but to achieve compliance it's only the bedroom rads. As for the cylinders, once again, it's not a current requirement so there is no need to change any cylinder, if it's an old unlagged cylinder you'd recommend it but it's not a requirement. The 150m2 rule is a decent size property fella. I've not seen it required in much under a 4 bedroom house if I'm honest. Quote Link to comment Share on other sites More sharing options...
Tim Kelly Posted February 28, 2012 Report Share Posted February 28, 2012 I bow to your superior knowledge. I will continue to tell my customers they need to comply with the recommendations rather than the letter of the law then. Quote Link to comment Share on other sites More sharing options...
