Do I Need Planning Permission to Move an Internal Wall? A Guide for Homeowners in England

You want to open up a room, knock through a doorway, or move a partition, and you are wondering whether you need planning permission first. For most houses the answer on planning is simple. The questions that matter more are whether the wall is holding anything up, whether Building Control needs to be involved, and whether anyone else has a say.

This is general guidance for homes in England. The rules in Wales, Scotland, and Northern Ireland are different. It is not advice on your home: I have not seen your property, and every house is different.

Key Takeaways

• Work that only affects the inside of a house is not usually “development” in planning terms, so it does not usually need planning permission. The big exception is a listed building, which can need listed building consent for internal works. Splitting a house into flats is also different: that is a change of use.
• Building Regulations are a separate question. Removing or altering a load-bearing wall is building work that needs Building Control. So can a non-load-bearing wall, where it affects fire safety, such as the walls around a staircase in a house with a second floor or attic room.
• Do not assume a wall is non-load-bearing. In older stone houses around Huddersfield, internal walls often carry floors, and they can also help hold the outside walls in place.
• If the work affects the wall you share with a neighbour, for example a new beam resting on it or a chimney breast coming out of it, or needs new foundations close to their property, the Party Wall etc. Act 1996 may apply.
• If you live in a flat, your lease may need the landlord’s consent before any wall is touched.

Planning Permission and Building Regulations Are Different Things

The two get confused all the time, and it is easy to see why. Both are forms of approval, and both can hold a project up if they are missed. But they answer different questions.

Planning is about development: how buildings look from outside, how they are used, and how they affect the area around them. Works that affect only the inside of a building, or that do not materially change how it looks from outside, are generally not treated as development at all. That is why moving an internal wall does not usually need planning permission. It is not that the work is “permitted development”; in most cases it is not development in the first place.

The exception is a change of use. Using new or moved walls to split a house into flats, or to create a separate home within it, can need planning permission even though nothing changes outside.

The Building Regulations are about how building work is done: structure, fire safety, and the other technical standards. They are checked by Building Control, either at the council or through a registered building control approver. This is where wall work most often needs approval.

So if someone tells you that moving a wall needs planning permission, they have usually mixed the two up. What you need to think about is the Building Regulations, and the structure.

When Wall Work Needs Building Control

• Load-bearing walls. Removing or altering a wall that carries load is building work under the Building Regulations. Building Control will normally ask for structural calculations for the beam or other support that replaces it. They will usually also want the new beam protected against fire, for example boxed in with suitable plasterboard.
• Fire safety. In a house with a second floor or an attic room, as some older terraces around Huddersfield have, the walls and doors around the staircase often form a protected escape route. Taking one out or opening it up can affect how people get out in a fire, and needs Building Control even if the wall carries no load. The same applies to the wall between a house and an integral garage, and to walls that separate one home from another.
• Electrics and gas. All electrical work has to be done safely to the Building Regulations. Some of it, such as a new circuit, also has to be notified, which a registered electrician can usually do for you without a separate Building Control application. Moving a socket in a wall you are taking down is a question for your electrician. Any gas pipe in the wall should be moved by a Gas Safe registered engineer.
• Heat and energy. Rarely relevant for an internal wall, but it can be where the wall separates a heated room from an unheated space such as a garage. If you are taking a garage into the house, that is a bigger change with requirements of its own.

A simple non-load-bearing stud partition, with none of these involved, may not need Building Control at all. If you are unsure whether your work does, ask your council’s Building Control team before you start. It is far easier to ask first than to put things right afterwards.

Is the Wall Load-Bearing?

Do not assume. Removing a wall that turned out to be carrying load can cause anything from cracked ceilings to a partial collapse.

Some signs suggest a wall may not be load-bearing: a thin stud wall, a wall running the same way as the floor joists above, or a wall added in a later alteration. None of them settles it. A wall running the same way as the joists can still carry a point load from above, and a stud wall can be carrying more than it was built for.

Signs that a wall may be carrying load include another wall directly above it, a wall that carries on down into the cellar below, a chimney breast directly above it, and loft struts or a water tank resting on it. In more modern houses, a ground-floor blockwork wall often carries the upstairs floor, even where the roof is carried by the outside walls. Not every block wall does, so treat this as a reason to check, not an answer.

In older stone houses, which make up much of the housing around Huddersfield, internal walls often carry the floors and sometimes the roof. They can also help hold the outside walls in place, so taking one out can affect the stability of a wall that is not being touched. That is one reason stone houses need particular care.

Working out whether a wall is load-bearing means looking at what sits on it and around it: the direction of the floor and roof timbers, what is above it on each floor, and how the load gets down to the ground, which in a house with a cellar means following it down into the cellar. A photograph of the wall on its own is not enough.

Listed Buildings and Conservation Areas

If your house is listed, the rules are different. Listed building consent is needed for works that would affect its character as a building of special architectural or historic interest, and that can include internal walls, even non-structural ones. Listing normally covers the whole building, inside and out, whatever its grade, not only the features described in the list entry. Some quite ordinary-looking stone cottages and terraces around Huddersfield are listed, so check rather than assume: you can search the National Heritage List for England online, or ask the council.

Doing such work without consent is a criminal offence, and the council can require the work to be reversed. If your house is listed, speak to the council’s conservation officer before any internal work, however small.

Being in a conservation area mainly affects outside changes. Moving an internal wall does not usually need permission just because the house is in a conservation area. If the work changes anything outside, such as a new window or door, the conservation area rules may apply.

Party Walls and Neighbours

Moving a wall inside your own house does not usually involve your neighbour. It can when the end of a new beam has to rest on, or be cut into, the wall you share with them, when a chimney breast is removed from that wall, or when new foundations have to be dug close to their property. In flats, it can also apply to the walls and floors between flats. In those cases the Party Wall etc. Act 1996 may apply. It sets out when the adjoining owners must be given notice and how any disagreement is settled. It is separate from both planning and Building Regulations. If there is any chance it applies, get advice from a party wall surveyor before work starts.

Flats

If you own a flat, the walls may not be entirely yours to alter. Many leases need the landlord’s consent before structural or other alterations, some forbid structural alterations altogether, and some walls may belong to the building rather than to your flat. In a flat, the walls around the entrance hall often protect your way out in a fire, and opening them up can need Building Control approval and a different fire safety approach. Check your lease and ask the landlord or managing agent first.

A Sensible Order to Do Things

• Check whether the house is listed, and if it is, speak to the council before anything else. If you live in a flat, check your lease.
• Find out what the wall does. Have it looked at by a structural engineer, especially if there is any doubt about whether it is load-bearing, or if it is in an older stone house. Find out, too, what runs through it: water or gas pipes, cables, or an old flue.
• If it is load-bearing, get calculations and drawings for the beam, what it rests on, and how the load reaches the ground.
• In a home built or refurbished before 2000, have any materials that might contain asbestos checked before the wall is disturbed.
• Check whether the work affects a neighbour, for example a beam resting on the shared wall, and take party wall advice if so.
• Involve Building Control where the work needs it, before work starts.
• Agree the scope with your builder, including temporary propping if the wall is load-bearing, and make sure nothing changes on site without your engineer being asked.
• Let Building Control see the work before the beam and its ends are covered up.

Where the work does need Building Control, keep the completion certificate, or the final certificate if you used a registered building control approver. It is the record that Building Control signed the work off, and you are likely to be asked for it if you sell.
