Want to replace the old rotten windows & have been told I need PP to do this

Can anyone explain why?

I am actually intending to change the windows but even if I replaced like with like (just double glazed) I would still need PP - it seems daft

Is it because it is a commercial building? If so why?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23688#Comment_23688 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23688#Comment_23688 Sun, 15 Jun 2008 09:35:01 +0100 nigel
I would have thought this would have formed part of your application for change of use from chapel to nursery.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23691#Comment_23691 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23691#Comment_23691 Sun, 15 Jun 2008 10:22:47 +0100 Pete1951 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23695#Comment_23695 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23695#Comment_23695 Sun, 15 Jun 2008 11:41:56 +0100 Katymac
OK I can see doing it for insulation I understand that

Now I just need to organise a bat survey & a flood survey to ensure changing the windows don't cause the chapel to flood/become infested with bats]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23706#Comment_23706 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23706#Comment_23706 Sun, 15 Jun 2008 16:28:46 +0100 CWatters
You don't normally need planning permission to change/replace windows unless the building is listed or in a conservation area.

You only need Building Control approval if you plan to install the new ones yourself. You don't need Building Control Approval if you use a company that's part of a "competent person scheme" (eg FENSA, CERTASS). They should give you a certificate after the work is done. You might need approval if the windows are structural.

Change of Use falls under bregs, not planning and is therefore not relevant unless you are changing use class, which you say you are not. You are correct that if there is no change of use then there is no requirement to upgrade for thermal requirements under this either. [Part L2B]

Have you considered whether you will require an Energy Performance Certificate [EPC]? You will need one if you let after October. These will rate the building A-G in terms of its energy performance. These may be expensive.

Planning are insisting on permission - Great Yarmouth - will be investigating the site (tomorrow maybe)

Who pays for the EPC - me or the landlord?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23714#Comment_23714 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23714#Comment_23714 Sun, 15 Jun 2008 19:15:04 +0100 Mike George https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23720#Comment_23720 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23720#Comment_23720 Sun, 15 Jun 2008 20:41:08 +0100 CWatters
"Change of Use falls under bregs, not planning"

It's very definitly a planning issue if the use class is different but I think katy said both are use class D1.

http://www.planningportal.gov.uk/england/genpub/en/1115314894558.html

It might also be a building regs issue as well because the regs for a nursery are likely to be different to a chapel or worship.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23721#Comment_23721 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23721#Comment_23721 Sun, 15 Jun 2008 20:51:19 +0100 CWatters
"Who pays for the EPC - me or the landlord?"

What sort of contract do you have with the landlord/owner?

If this is a leasehold then normally you need the leaseholders permission for alterations. The lease will spell out who is responsible for maintenance. Typically it's the tennant, sometimes via a residents association or similar.

If you are just renting the building and paying a market rent the landlord would pay for all structural repairs (eg new windows). If you have some kind of deal whereby you get use of the property at a discount in return for "doing it up" then be very careful. What stops him kicking you out the day after you finish spending thousands of pounds doing up his building for him? It all sounds like a very strange arrangement you have. Particularly as you have to ask who pays. The answer should be in the contract you have with him.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23722#Comment_23722 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23722#Comment_23722 Sun, 15 Jun 2008 21:03:07 +0100 Katymac https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23724#Comment_23724 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23724#Comment_23724 Sun, 15 Jun 2008 21:05:41 +0100 Mike George Posted By: CWattersMike,

Yes, you are right, I do apologise. Completre brainmalfunction today [at least hopefully only today] I have building regs on the brain at the moment. In my defence, one of the triggers for Part L improvements is where there IS a Material Change of Use, and this may include upgrading windows. The change of use itself is of course a Planning issue.

EDIT So to clarify [in this instance] planning permission for change of use is not required, and neither is any Building regulation improvements [Part L] which would be triggered by such a change.

However, Part L is pretty much 'catch all' these days, and where more than 25% of thermal elements [walls/floors/roof] are touched, they will need to be upgraded.

Further improvements may also be recomended as part of the EPC paperwork]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23796#Comment_23796 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23796#Comment_23796 Mon, 16 Jun 2008 18:31:07 +0100 CWatters Posted By: KatymacContract is still being written

Sounds very risky. Do get that contract sorted with input from a good solicitor. I think I'd want to get some kind of shared ownership. Lets say the building is worth £X as it is. You are investing £Y in doing it up therefore you should own Y/X fraction of the property. Get your share in the property recorde with the land registry for example. Think about _all_ the eventualities such as what happens if the landlord dies. Would your contract die with him? Would his executors be able to kick you out?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23810#Comment_23810 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23810#Comment_23810 Mon, 16 Jun 2008 20:01:14 +0100 Katymac https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23816#Comment_23816 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23816#Comment_23816 Mon, 16 Jun 2008 21:18:14 +0100 rogerwhit
Planning permission if required will cover the appearance, eg so that whatever it's used for, it still looks something like a chapel ...]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23826#Comment_23826 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1919&Focus=23826#Comment_23826 Mon, 16 Jun 2008 22:21:11 +0100 biffvernon The main issue involved is thermal performance.
Generally U-value less than 2.
Also:
Safety glass next to doors and if bottom of window is less than 800 mm above floor. Emergency egress in some situations. Ventilation.]]>
