Skipping the rules might seem quicker or cheaper when building work on your home.
However, failing to get approval for proper building regulations can lead to serious problems, from fines to being forced to undo the work.
This guide explains the cost of avoiding building regulation compliance, what to do if you’re already in trouble, and how to get approved correctly.
What Are Building Regulations?
Building regulations are legal standards that the UK government sets to ensure any building work is safe, efficient, and structurally sound.
They apply to most projects, including:
- Extensions
- Loft conversions
- Alterations to electrics, plumbing, or walls
Unlike planning permission, which is about appearance and use, building regulation compliance is about safety and performance.
Do I Need Building Regulations Approval?
Yes—in almost all cases.
You need to apply for approval of building regulations before starting major work. This applies whether you’re:
- Renovating a kitchen
- Converting a garage
- Adding a bathroom
- Building an extension
If you’re unsure, always check with your local authority’s building control.
What Happens If You Build Without Approval?
Doing building work without the proper approval has real consequences:
1. Legal Fines
You may face enforcement from the local authority or even a cour,t where an unlimited fine can be issued.
2. Tear-Down Orders
You may be required to put the work right or remove it at your own expense.
3. No Completion Certificate
Without a valid completion certificate, your home may:
- Fail surveys when selling
- Trigger buyer withdrawal
- Lower the value of your home
A lack of a building regulation completion certificate can stall a sale or lead to renegotiation.
Can You Sell a House Without Building Regulations?
Technically, yes—but it’s risky.
Buyers or lenders often request proof of building regulation compliance.
If you don’t have it, you may need:
- A regularisation certificate
- Indemnity insurance to cover potential risks
Many mortgage lenders won’t proceed without documentation of building regulations.
What Is a Regularisation Certificate?
This is retrospective approval for building work carried out without notice.
To get one, you must:
- Apply through your local building control department
- Allow a building inspector to assess the work
- Make necessary changes to meet standards
Note: Not all work qualifies for regularisation.
When Might You Need to Apply for Retrospective Approval?
You may need a regularisation certificate if:
- You recently bought a home with non-compliant building work
- You discover past alterations done without approval
This process helps buyers and sellers resolve hidden compliance issues before a sale.
What Is Indemnity Insurance?
Indemnity insurance is a legal workaround. It covers financial loss if the local authority later acts on work without building regulations.
This is often used when:
- Time is tight (e.g. house sale)
- It’s too costly to undo work
However, it’s a temporary fix. It does not guarantee the work is compliant or safe.
What Work Requires Approval?
Here are common projects that need building regulations approval:
- Structural alterations
- Window or door replacements
- Boiler or heating system updates
- Electrical rewiring
- Loft or garage conversions
- Wall removals
Even small projects may need to comply with the building regulations.
Who Checks Compliance?
A building control officer from your local authority or a registered building control approver ensures your work:
- Meets building standards
- Is carried out safely
- Follows the 2010 framework
They inspect the site during the work and issue the completion certificate.
How Do I Apply for Building Regulations Approval?
You can apply in two ways:
1. Full Plans Application
- Submit architectural drawings and details
- Wait for written approval before work starts
2. Building Notice
- Simpler and quicker
- Only suitable for small domestic projects
Speak to your local building control to find out the best approach.
Competent Person Scheme
Hiring tradespeople through the competent person scheme means they self-certify their work.
This is common for:
- Electricians
- Gas engineers
- Boiler installers
It’s still your responsibility to comply with building regs overall.
Why Building Regs Matter for Safety and Peace of Mind
Using building regulation approval gives you:
- Legal protection
- Buyer confidence
- Safety for your family
- Ensure your home is built to the highest standards
Avoid shortcuts. Work which does not comply can result in future costs, stress, and sales problems.
What If the Work Is Already Done?
Don’t panic.
You can:
- Apply for retrospective building approval
- Request a regularisation application
- Contact the local authority about work you didn’t carry out
- Get indemnity insurance if necessary
But remember: prevention is cheaper than repair.
Final Word: Always Comply With Building Regulations
From kitchen refits to home extensions, ensure your project follows the law.
The costs involved in skipping building regulation checks are not worth it.
Check with your council, hire the right professionals, and always get proper building regs approval.
