Do I Need Planning Permission for a House Extension in Nuneaton?
One of the first questions homeowners ask when planning a house extension is: Do I need planning permission? The answer isn’t always straightforward, but understanding the rules can save you time, money, and complications down the line.
In Nuneaton and across Warwickshire, planning rules are set by local authorities, and some work falls under “permitted development” — meaning you can build without formal permission. However, there are important exceptions and conditions to know about. This guide will walk you through exactly when you do (and don’t) need planning permission for a house extension.
What Is Permitted Development?
Permitted development is a special category of building work that doesn’t require formal planning permission from your local council. It’s a streamlined route designed for common, low-impact projects — and extensions often fall into this category.
In England, permitted development for house extensions is governed by the Town and Country Planning (General Permitted Development) Order. This allows homeowners to build extensions up to certain sizes without submitting detailed planning applications, as long as specific conditions are met.
Key Benefits of Permitted Development
- Faster process: No lengthy planning application or waiting for council decision
- Lower costs: No professional planning application fees (though you still pay building regulations)
- Less bureaucracy: Fewer forms and fewer reasons for rejection
However, permitted development is not a free pass. You must still comply with building regulations, get proper structural designs, and meet all the conditions set out below.
When You DON’T Need Planning Permission
Most single-storey rear extensions in Nuneaton qualify for permitted development, providing they meet these conditions:
Single-Storey Extensions
Permitted development rules allow a single-storey extension if:
- It extends no more than 4 metres from the back of the original house (for detached homes, this can be 8 metres)
- It doesn’t cover more than 50% of the plot’s total ground area
- The roof height doesn’t exceed the height of the main house
- It’s at least 2 metres away from the boundary if within 2 metres of the original house
- It maintains at least 0.6 metres distance from any boundary when part of the structure is within 2 metres of the house
- It doesn’t protrude beyond the front building line of the house (except for terraced homes under strict conditions)
- The materials broadly match the existing building
- There’s no basement or below-ground works
Double-Storey Extensions (Limited Permitted Development)
Double-storey extensions have tighter permitted development rules:
- Single-storey permitted development limits apply to the ground floor
- The first-floor extension can only go as far back as the ground floor extension (no stepping back)
- The same eaves and ridge height rules apply
- Many two-storey extensions end up needing planning permission because they exceed these limits
When You DO Need Planning Permission
Several situations require formal planning permission. If your extension falls into any of these categories, you’ll need to submit an application to Nuneaton and Bedworth Borough Council:
Extensions That Always Need Permission
- Front extensions (except terraced homes under specific conditions)
- Side extensions that are clearly visible from the road
- Extensions on terraced or semi-detached homes (stricter rules apply)
- Extensions exceeding permitted development limits (over 4 or 8 metres, or covering more than 50% of the plot)
- Two-storey extensions with complex layouts or configurations
- Listed buildings (always need permission, regardless of size)
- Properties in conservation areas (stricter rules; often need permission)
- Roof extensions, loft conversions (loft conversions are particularly strict in some areas)
- Extensions with basements or below-ground elements
Extensions on Properties with Article 4 Directions
An “Article 4 Direction” is a local planning restriction that removes permitted development rights in specific areas of Nuneaton and Warwickshire. These are often put in place to protect:
- Conservation areas
- Areas of outstanding natural beauty
- Historic town centres
- Neighbourhoods where the council wants stricter control over changes
If your property is in an Article 4 area, you must obtain planning permission even for standard single-storey extensions.
You can check if your property is subject to an Article 4 Direction by:
- Searching the Nuneaton and Bedworth Borough Council planning portal online
- Contacting the council’s planning department directly
- Having a surveyor or planning consultant check for you (highly recommended)
Building Regulations: Always Required
Here’s a critical point that many homeowners miss: even if you don’t need planning permission, you always need building regulations approval.
Building regulations are separate from planning permission. They cover:
- Structural safety and integrity
- Insulation and energy efficiency
- Electrical safety and installations
- Drainage and water systems
- Fire safety and means of escape
- Access and accessibility
When your extension is complete, building control will inspect the work and issue a completion certificate. This is essential for:
- Insurance claims
- Future house sales
- Mortgage lender requirements
- Your peace of mind

How to Check Your Requirements
If you’re unsure whether your extension needs planning permission, follow these steps:
Step 1: Check Your Location
Is your property in a conservation area, on a listed building register, or subject to an Article 4 Direction? Visit the Nuneaton and Bedworth Borough Council website or call them directly on the planning enquiries number.
Step 2: Assess Your Extension Type
- What type of extension are you planning? (rear, side, front, single-storey, double-storey)
- How far will it extend from the house?
- How much of the garden will it cover?
Step 3: Get Professional Advice
This is where a builder with planning experience is invaluable. At Parker Grears, we offer a Quantity Surveyor (QS) consultation at £240 + VAT. During this consultation, we’ll:
- Determine if planning permission is needed
- Advise on timescales and next steps
- Identify any potential challenges
- Give you accurate cost estimates
This upfront investment often saves thousands in avoided mistakes or unnecessary applications.
The Timeline: Planning vs. Permitted Development
Understanding timescales helps with project planning:
Permitted Development Route
- Building regulations application: 1–2 weeks for approval
- Inspection and completion: Typically 4–8 weeks during construction
- Total project duration: Usually 8–12 weeks
Planning Permission Route
- Application submission: 1–2 weeks to prepare
- Council decision: 8 weeks (standard); can extend if they request further information
- Building regulations: Additional 1–2 weeks after planning approval
- Total project duration: Usually 16–24 weeks or longer
Common Misconceptions About Planning Permission
“My neighbour didn’t get permission, so I don’t need it either.”
Your neighbour’s situation may be different. Even if their property looks similar, factors like conservation area status or Article 4 Directions could apply differently.
“Planning permission and building regulations are the same thing.”
No — they’re completely separate. You can have permitted development (no planning needed) but still require building regulations approval.
“I can build first and apply for permission later.”
This is risky. Building without permission when it’s required can result in enforcement action, costly demolition, or legal disputes. Always get clarity first.
“Loft conversions are quick and easy because they’re permitted development.”
Loft conversions have very strict rules, and many require planning permission. Some Warwickshire areas restrict them entirely.
