Hi all, I couldn't figure out how to introduce myself but we've renovated a 17th century terrace almost finished - ish. We've had double glazing put in & the agreement was we'd have no trickle vent in the living room window as we would have one in the other window in that room - at this point I had no idea there were exemptions for conservation areas & the company didn't tell me. On the contract all other windows mention the dreaded trickle vents but the living room window does not. Basically what I would like to know is should I expect a full window replacement or a blanking plate to remedy this? I'm concerned about the noise they allow in as we're on a busy high street. The windows are beautiful, look like the old originals but they've cost a fortune & I feel a bit miffed. What are your thoughts?

My question concerns window ventilation BC compliance rules for fitting windows to a living room in an existing property with a woodstove. It may be basic and obvious for the pros but as a householder I am unsure. Safety is fundamental but so is prospective BC signoff of the windows. The planning baseline for this living room space was an open fireplace, chimney + hearth airbrick and five windows with trickle vents (1996/7 approved plans), Egress door in room (not a requirement but it's there) Since then an inset wood stove has replaced the open fireplace under an installer self-certification. As part of this an optional external air supply tube was added to the end wall behind fireplace to provide direct external ventilation for stove combustion air. This is beyond stove install minimum compliance regulations which relies on room air to a greater extent without getting into that here. The stove install is believed compliant as of its install date - hearth, CO detector, stove space vents, liner etc. Works well - way better than the open fire - no longer extracts all the centrally heated air from the house to heat the county. Proposed window change and trickle vent issue now It is proposed to replace all the windows in the room. 3 of the 5 are candidates for fixed lights as they are never opened but they could lose their trickle vents in this implementation scenario as not all suppliers in play offer the combination. Over both changes (external air supply and trickle vents) - we are still likely to be "up" from the baseline in room ventilation but this may not be the only factor in determining BC compliance for the windows - as the direction of travel is "less than existing" viewed in isolation looking at the windows. There do not appear to be any relevant fire egress considerations as the room has doors to main building doors nearby and a direct egress door in the room itself There are two other opening windows in the room which are keeping their opening sashes and trickle vents regardless of scenario. Any thoughts on this combination is appreciated. Whether the proposed scenario is valid or help on the rule it likely fails on so I can look at the most cost/energy efficient solution. Specifying opening lights for tiny and light well windows - which have pretty much never been opened in 20 years or had their trickle vents touched is to be avoided if a compliant design without either is possible. Thank you Graham
