Essential Advice: Learn from Common Mistakes

When you're thinking about changing your doors and windows, knowing about planning permission and building regulations upfront can save you a lot of hassle down the line. We'll share a real story to show you why, along with essential advice for your project.

A Costly Lesson: What Happens When You Don't Check

Imagine this situation: A flat owner decided to swap out their worn-out windows. They mistakenly thought that improving the property's look, especially since their flat wasn't in a conservation area, meant they wouldn't need planning permission. The double-glazing company completed the installation but clearly told the owner that checking planning and building rules was *their* sole responsibility.

The real trouble started three and a half years later when the owner put the flat on the market. During the conveyancing checks, the buyers' solicitors requested proof that all necessary approvals were in place for the window replacements.

Because it was a leasehold property, you actually needed the freeholder's permission to install new windows. The owner hadn't asked for it, thinking that the property's improved appearance and the passage of time would make it less of an issue. This assumption proved to be a major obstacle. The freeholder wouldn't give their approval unless the council granted retrospective planning permission, meaning the buyers' solicitors wouldn't proceed. Consequently, the owner had to apply for this after-the-fact permission, pushing back the sale by two months.

Looking back, the owner realised they should have secured consent from both the local council and the freeholder before replacing any windows.

Your Essential Checklist for Door and Window Updates

• Whenever you hire a company to do work on your property, always scrutinise the terms and conditions carefully.

• Should your installer not be part of FENSA or an equivalent certified scheme for competent persons, or if you choose to do the installation yourself, you'll have to obtain full building control approval from your local authority.

• Prior to committing to any contract for new glazing, always ask your installer if they are able to self-certify that the work meets Building Regulations.
