Building something new? Converting your loft? Knocking down a wall? Doing a large refurbishment? Before the dust starts flying, there’s something important you need to sort – and no, it’s not the cement.
It’s your paperwork.
If you’ve ever asked what are building permits, you’re not alone. A lot of homeowners and small developers jump straight into the work without realising there’s a legal process involved. That’s when the problems start.
Let’s look at what building permits are, why you might need one, and what happens if you don’t bother.
So, What Are Building Permits?
In the UK, a “building permit” is officially known as Building Regulations Approval. It’s not the same as planning permission – although sometimes you’ll need both.
A building permit confirms that the work you’re doing meets the national safety and construction standards. These rules cover:
- Structural stability
- Fire safety
- Energy efficiency
- Damp proofing
- Ventilation
- Plumbing
- Electrical safety
- Access for disabled people
Whether you’re putting in a new bathroom, extending your kitchen, or converting a garage into a bedroom, Building Control wants to make sure it’s done right – and done safely.
When Do You Need One?
You’ll need Building Regulations Approval for most types of structural work, including:
- Home extensions
- Loft conversions
- Garage conversions
- New windows or doors (especially if altering the structure)
- Removing internal walls
- Installing a bathroom where there wasn’t one before
- Major rewiring
- New boilers or heating systems
- Building a conservatory (if it doesn’t meet the exemption rules)
Even things like roof work or underpinning can need approval.
How Do You Get One?
There are two main routes:
- Full Plans Application
You submit detailed drawings and specs before work starts. The council or private inspector checks everything and either approves it or asks for changes.
- Building Notice
This is faster but more basic – suitable for smaller domestic jobs. No plans are submitted up front, but an inspector still checks the work as it progresses.
Both options involve site visits at various stages to make sure everything meets current standards.
You can apply through your local authority or use an approved private building inspector. Either way, it needs to be sorted before or as soon as work begins.
What Happens If You Skip It?
Some people think they’ll save time or money by “forgetting” the paperwork. But that’s a risk you really don’t want to take.
Here’s what could go wrong:
- You might have to rip the work out if it doesn’t meet the rules
- You could face fines if it’s reported
- Selling your home gets harder – buyers and solicitors ask for completion certificates
- Insurance claims could be rejected if something goes wrong
- Future work may be refused due to missing approvals
It’s not just red tape. These permits protect you and your home – now and in years to come.
What If You’re Using a Builder?
Some builders will say “Don’t worry, I’ll take care of it.” That’s fine – as long as they actually do.
However, remember that you’re legally responsible as the homeowner. If they forget to notify Building Control or cut corners, it’s on you. Always double-check that everything’s in place and get copies of all paperwork.
Does It Apply to DIY Work?
Yes – the same rules apply whether you’re hiring professionals or doing it yourself. Even if you’re just updating your bathroom with a new shower and moving the pipes, it might still need approval.
Check The Rules
So, what are building permits? They’re your official permission slip to carry out building work safely and legally. They’re not there to hold you back – they’re there to protect you, your family, and your investment.
Before starting any project, no matter how small it may seem, check the rules. One quick phone call to your local council can save you a mountain of stress later.
Because nothing ruins that shiny new extension quite like a letter from Building Control telling you to take it down.
