There’s a moment early in most renovations where the sledgehammer feels more appealing than the paperwork. You’ve got the vision, the mood board, maybe even the tradespeople booked in, so why not just get started? The trouble is, skipping the groundwork is exactly how straightforward projects turn into expensive, drawn-out ones.
It happens more often than you’d think. Research found that 12% of homeowners who completed a major renovation or extension either failed to get the right planning permission or didn’t realise they needed it in the first place, a mistake that can mean costly delays or being forced to undo completed work.
The good news is that most of these problems are avoidable with a bit of planning before the first wall comes down. Here’s what to check first.
Your Pre-Renovation Checklist
Work through these steps before any demolition starts, and you’ll save yourself time, money and a fair amount of stress along the way.
Check Whether the Wall Is Load-Bearing
Not every wall you want gone is just standing there for decoration. Some are holding up the floor or roof above, and removing one without support in place can cause serious structural damage, or worse. A quick way to get a clue is to check which direction the floor joists run in the room above, though this isn’t foolproof on its own. If there’s any doubt at all, don’t guess. A builder or engineer can usually tell within minutes on a site visit, so get it checked before you pick up a tool.
Bring In a Structural Engineer If It Is
If the wall turns out to be load-bearing, you’ll need a structural engineer to calculate what sort of support, usually a steel beam known as an RSJ, is needed to safely take its place. They’ll also make sure the new setup meets building regulations before any work is signed off. The Institution of Structural Engineers has a directory that makes it straightforward to find a qualified engineer near you, so it’s worth using before work starts rather than after something’s gone wrong.
Sort Your Building Regulations and Permissions
Plenty of internal renovation work doesn’t need planning permission, but building regulations are a different matter and apply far more often than people expect, especially where structure, drainage or electrics are involved. Skipping this step can mean being asked to undo completed work later, so check what applies to your project with your local council or via GOV.UK’s building regulations guidance before anything gets torn out.
Tell Your Neighbours and Check Your Insurance
A quick heads up to the people next door goes a long way when there’s drilling, banging or a skip on the drive for weeks on end, and it tends to keep things friendly if the work overruns. While you’re sorting the practicalities, it’s also worth calling your home insurer to confirm your policy still covers the property while building work is underway. Standard cover doesn’t always extend automatically once structural changes begin, so it’s better to check first than find out the hard way.
Arrange Your Skip and Sort Waste Before You Start
Renovations generate a lot more rubble, packaging and old materials than most people expect, and having nowhere to put it slows work down fast. Work out roughly how much waste your project will create and book a skip in good time, sized for the job rather than guessed at, since undersising usually means paying for a second one later. Proskips skip hire covers sites across the UK and can help you work out the right size before the first wall comes down. If the skip needs to sit on the road rather than your drive, check with your council first whether you need a permit for that too.
Set Aside a Contingency Budget
Even with the best planning, older properties especially have a habit of throwing up surprises once work is underway, from hidden wiring to unexpected damp. Setting aside 10 to 20% of your total budget as a contingency fund means these discoveries become an inconvenience rather than a crisis. Our guide to common renovation surprises goes into more detail on what tends to catch people out and how to budget for it properly.
Conclusion
None of these checks take long, but skipping them is how straightforward renovations turn into stressful, expensive ones. A wall that turns out to be load-bearing, a missing permit, or nowhere to put the rubble can each bring a project to a halt on their own. Work through this list before the first wall comes down, and you’ll start your renovation on solid ground, in every sense.
