BTW the company want to use an F220 contract for minor building work. Presumably that is a good thing? Cheers

Hi, I'm about to give some work to a company to draughtproof/overhaul and double glaze the windows in our house. Can someone recommend what I should do in order to check the legitimacy of the company before any contract is agreed or signed off. Presumably getting the VAT number is an...

Hi, a recent post of mine talked about wanting to have my sash windows refurbed/overhauled/draughtproofed/double glazed etc. Just wondered if there was anyone out there who'd be interested in quoting for the work. We've had a couple of people come and take a look but I haven't really been...

Thanks baxiengineer. To date the quotes we've had indicate labour for this kind of installation at around £1,800 (inc VAT). Given your estimate, that seems a resonable price. Is it a 2-3 day job?

Most engineers are recommending between 30 and 37kw. I posted the 40cdi as an example. The original question still remains however, for a bog standard installation, what cost would be reasonable to install the hardware as described (assuming no extra work is required)? I appreciate it's...

This is all interesting stuff. It's certainly fair to say that the worcester boiler and megaflow tank do seem to cost a significant premium. I don't feel tied to anything but then again the warranties surely provide a certain piece of mind? How often does the Megaflow lose 'the bubble'? Is...

In terms of tank size only upwards of 210 litre has been recommended, the vast majority suggesting 250. It's a big house BTW, 2,400 sqft.

Thanks for all this advice, keep it coming. I believe it was over 3 bar measured at the furthest outside tap. The engineer remarked that the pressure was especially good. Yes 3 bathrooms but realistically it's very unlikely more than 2 will be in use simultaneously. I always think a...

Thanks for the reply. That's a bit of a minefield for the customer don't you think?! How do they make a decision about which boiler/tank combo to go for?

Ok but in terms of installation costs? Let's say that the boiler and tank plus other hardware is @ £3,000. Given the straightforward nature of the job, what would be a reasonable cost to install this system? £500? £1,000? £2,000? etc BTW of the 7 tradesmen I have spoken to regarding...

Hi, just wondering whether any of you out there could indicate whether I'm getting decent value or not. I have a 15-20 year old vented cylinder central heating system (I have a 5 bedroom, 3 bathroom terraced house). I'm looking to replace this system with an unvented system. I have excellent...

I'm pleased to report pressure of 3+ bar and water flow of 25+ litres per min

Thanks Tony. Ok I'll get a more accurate reading tonight. We live in a 5 bedroom house which fairly soon will have 3 bathrooms. However we're only currently a family of 3 and are very unlikely to be a family of more than 4 so 3 bathrooms might be a little misleading in terms of use.

Hi, not timed but I'd estimate at full speed I'd get a litre every 3-4 seconds. 15-20 l/min therefore. Mains pressure is powerful I would say. I'll time it tonight. Not sure about the lead pipe. The internal stop cock looks fairly old if that's any indication. Will take a look for the...

No-one with any view?

Just reading about thermal stores. They seem to potentially be the best system to install (no pressure build up risk). Are there any drawbacks or trade offs with the unvented mains pressure solutions?) Expensive perhaps? Thanks in advance.

Yes sounds like I need to shop around more. Can I ask, did you employ London based firm. That sounds extremely cheap to me. Can anyone recommend anyone in London (North ideally) Thanks

No, I meant that there are some minor repairs also required. I appreciate the general overhaul is not a repair. You mention labour of 20-25/hr which seems very reasonable but how long would it take to do a standard 2 sash window? Thanks for your help.

In essence, yes just for this. They will also carry out minor repairs, balance the window and ensure it's fully operational (as one would expect). I assume the labour required to do the work (including window removal, grooving the sashes etc) would stretch over a few hours also? Out of...

Thanks for the response. We've had 3 quotes, 2 roughly around this mark and 1 that was significantly higher (30%). The 2 roughly equal quotes were from a lone joiner locally and a smallish company based in Kent. Both seemed to know their stuff and were very affable. They were both...
