Planning permission, building regulations, listed building consent: which one you actually need
Your builder says you need nothing. Your neighbour says you need permission. They are probably answering two different questions, and there are five of them.
Planning permission, building regulations and listed building consent are three separate systems, with different law behind them, different people deciding and different consequences for skipping them. One job can need all three, or none. Permitted development is a fourth thing again: a right you already hold rather than an application you make.
The short version
- Your builder and your neighbour can both be right. They are almost certainly answering different questions, because there are five regimes here and only one of them is planning permission.
- Permitted development is planning permission that has already been granted to you by a statutory instrument. There is nothing to apply for, and it says nothing at all about building regulations, listed buildings or party walls.
- Listed building consent is the one that bites hardest. There is no minimum size of job, the test is effect on character, and doing the work without consent is a criminal offence whether or not you knew the building was listed.
- Conservation area consent has not existed in England since 1 October 2013. If a page tells you to apply for it, that page has not been updated in over a decade.
- Planning permission is not a defence to a building regulations breach, and building control signing off the work is not a defence to a planning breach. They do not talk to each other.
Start here
Five separate systems, and only one of them is planning permission
The reason you have been told two different things is that the two people were answering two different questions. A builder saying “you don’t need anything” usually means you do not need planning permission, and they may well be right about that. A council officer or a neighbour saying “you’ll need permission” may be talking about the conservation area, the listing, or the fact that the work is notifiable to building control. Both statements can be true at once.
So the first useful move is to stop asking “do I need permission” and start asking which of five regimes applies. They are genuinely separate. Different Acts, different decision-makers, different tests, different timescales, and different things that happen to you if you ignore them.
| Regime | Legal basis | Who decides | What triggers it | If you skip it |
|---|---|---|---|---|
| Planning permission | Town and Country Planning Act 1990 | Your local planning authority | Development that is not permitted development | Enforcement notice, or a retrospective application. Not a crime in itself, with two exceptions below |
| Permitted development | The General Permitted Development Order 2015 (SI 2015/596) | Nobody. It is automatic | Work that stays inside the limits in Schedule 2 | Nothing to skip. You may apply for a lawful development certificate if you want proof on paper |
| Building regulations | Building Act 1984 and the Building Regulations 2010 | Local authority building control, or a registered building control approver | “Building work” as defined in regulation 3 | Enforcement, and no completion certificate, which is the thing a buyer’s solicitor asks for |
| Listed building consent | Planning (Listed Buildings and Conservation Areas) Act 1990, section 7 | Your local planning authority | Works affecting the character of a listed building as one of special interest | Criminal offence under section 9. Up to two years on indictment |
| Relevant demolition | Town and Country Planning Act 1990, section 196D | Your local planning authority, through planning permission | Demolition of a building in a conservation area in England | Criminal offence. Up to two years on indictment |
Read down the last column and the shape of the problem becomes clear. Three of these five are administrative and recoverable. Two are criminal. Almost every argument on a building site is about the first column when it should be about the last one.
The one everybody misunderstands
Permitted development is a right, not an application
Permitted development is not an exemption from planning permission. It is planning permission, granted to you in advance by an order made by the Secretary of State. The order is Schedule 2 of the General Permitted Development Order 2015, and Part 1 is the part that covers houses. If your work sits inside the limits written there, permission already exists and there is nothing to apply for.
That matters in two directions. Nobody can make you apply for something you already have. But nobody is checking, either, so if you have measured wrong the permission was never there and the first you hear of it may be an enforcement notice.
If you want proof on paper, the answer is a lawful development certificate. It is an application to the council asking them to confirm that what you propose is permitted development. It is not permission, because you already have that. It is evidence, and it is the thing a buyer’s solicitor will be happy to see in five years.
What permitted development does not cover
This is where most of the trouble starts. Permitted development speaks only to planning. It says nothing whatever about:
- building regulations, which are a separate regime with a separate trigger;
- listed building consent, which is a separate Act entirely;
- the Party Wall etc. Act 1996, if you are working on or near a shared wall;
- the highway authority, if scaffolding or a skip is going on the public road;
- the Environment Agency, if the work touches a watercourse or a flood zone.
Permitted development rights can also be taken away. A planning condition on an earlier approval can remove them, which is common on newer estates, and so can an article 4 direction made by the council. Rights are also restricted in conservation areas, national parks, areas of outstanding natural beauty and world heritage sites, which the order calls article 2(3) land.
Regime one
Planning permission: is this acceptable in this street
Planning is about the effect of your work on everybody else. Appearance, scale, overlooking, traffic, trees, the character of the area. It is not about whether the roof will hold up. That is a different regime with a different test, and confusing the two is the single commonest mistake homeowners make.
The trigger is development that is not permitted development. Development has a statutory meaning: building, engineering, mining or other operations, or a material change of use. Works that affect only the interior, or that do not materially affect the external appearance of a building, are not development at all. That is why a like-for-like re-roof usually needs no planning permission and a change from natural slate to a heavy interlocking concrete tile might. We have set the roof case out in full in whether you need planning permission to replace a roof.
If you skip planning permission, the consequence is usually administrative rather than criminal. The council can serve an enforcement notice requiring you to put it back, and you can apply retrospectively, which sometimes succeeds and sometimes does not. Ignoring an enforcement notice is itself an offence, but the original unauthorised work is not, unless it involves a listed building or demolition in a conservation area.
Who decides is worth checking rather than assuming. It is not always your district or unitary council. Inside a national park the park authority is the planning authority, and there are patches of England where the planning application, the building control notification and the scaffold licence for the same job go to three different organisations. Along the Dorset and Hampshire border that is the normal state of affairs, not an oddity.
Regime two
Building regulations: will it stand up, keep the water out and hold the heat
Building regulations are about performance and safety, and they apply whether or not anybody can see the work from the street. Structure, fire, damp, ventilation, insulation, drainage. A job can be entirely invisible from the pavement, need no planning permission at all, and still be notifiable building work.
The trigger is “building work” as defined in regulation 3 of the Building Regulations 2010. Stripping a pitched roof back to the rafters and rebuilding it is building work. Replacing the waterproof membrane on a flat roof is building work. Structural alterations are building work. Replacing a few slipped tiles is not.
Where it applies, regulation 12 of the Building Regulations 2010 gives you two routes: a building notice or an application for building control approval with full plans. There is a third route that most homeowners never hear about, which is that certain work, roof coverings among it, can run under a competent person scheme, where a contractor who is a member of one self-certifies the work, lodges it with the council and sends you the certificate afterwards. Which of the three applies changes what the job costs you in weeks, and we have compared them in building notice, full plans or a competent person scheme.
The consequence of skipping building control is quieter than an enforcement notice and lasts longer. The council can require the work to be opened up or put right, but the practical problem is the paperwork. When you sell, the buyer’s solicitor asks for the completion certificate. If there is not one, the sale stalls while you apply for regularisation, and regularisation on a roof means somebody has to be able to see what is under the covering.
One point of vocabulary, because it is a good test of how current your adviser is. Since 2024 the private-sector alternative to council building control is a registered building control approver, and the individual doing the inspecting must be a registered building inspector. The old term was “approved inspector”. Anybody still using it is working from pre-2024 material.
Regime three
Listed building consent: the one where getting it wrong is a crime
Listed building consent is strict. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 says that no person shall execute or cause to be executed any works for the demolition of a listed building, or for its alteration or extension in any manner which would affect its character as a building of special architectural or historic interest, unless those works are authorised.
Read that again and notice what is missing. There is no size threshold. No square metre figure, no percentage, no distinction between repair and alteration. The test is effect on character, and a small job can affect character more than a big one. Repointing one elevation in the wrong mortar is a common example, and we have written about that in listed building consent for repointing and rendering.
Before anybody starts. Carrying out works that affect the character of a listed building without consent is a criminal offence under section 9 of the same Act. On summary conviction the maximum is six months or a fine or both. On indictment it is up to two years or a fine or both, and in fixing the fine the court must have regard to any financial benefit that has accrued or is likely to accrue from the offence. Not knowing the building was listed is not a defence, and the grade makes no difference to the offence.
What listing actually covers
Three things surprise people, in this order.
- The interior is listed too. The listing protects the whole building, inside and out. A staircase, a fireplace, panelling, plaster mouldings and original joinery are all part of it, even where the official list entry does not mention them. This is the commonest surprise by a wide margin, because people assume the list entry is the specification. It is a description, not a schedule.
- The curtilage is listed too. Structures within the curtilage that formed part of the land on 1 July 1948 are treated as part of the listed building. A boundary wall, an outbuilding, a coach house, a privy. So a garden wall you thought was just a garden wall may need consent to alter or take down.
- The grade is irrelevant to the offence. Grade I, Grade II* and Grade II are all protected by the same section 7 and the same section 9. The grade affects how hard consent is to get and who has to be consulted. It does not soften the criminal law.
There is one narrow defence in section 9, for works that were urgently necessary in the interests of safety or health, or to preserve the building, where written notice was given to the authority as soon as reasonably practicable. It is much narrower than people hope. A slate coming loose in a gale is not usually enough on its own.
The correction
Conservation area consent has not existed in England since 2013
If a builder, a website or a well-meaning neighbour tells you to apply for conservation area consent, they are working from law that was repealed over a decade ago. Conservation area consent was abolished in England on 1 October 2013 by section 63 of, and Schedule 17 to, the Enterprise and Regulatory Reform Act 2013.
What replaced it is not a lighter regime. It is a heavier one. Demolishing an unlisted building in a conservation area is now called relevant demolition, and it needs ordinary planning permission. Doing it without that permission is a criminal offence under section 196D of the Town and Country Planning Act 1990, carrying up to two years on indictment. The section is written so that it catches the person who causes or permits the demolition as well as the person swinging the hammer, which means the homeowner as well as the contractor.
Wales kept conservation area consent for another eleven years. It went there on 4 November 2024, under the Historic Environment (Wales) Act 2023. So if you are reading advice written for Wales, or written before that date, it may be correct for Wales and wrong for England. Scotland and Northern Ireland run their own systems and both still have conservation area consent.
The practical point for a homeowner is this: in a conservation area, taking something down is a far more serious question than putting something up. Erecting a garden wall may be permitted development. Demolishing the one that is already there may be a crime. Being in a conservation area does not, on the other hand, remove your right to re-roof your house, which is a myth we have taken apart separately in what actually changes when you re-roof in a conservation area.
The traps
Two consequences almost nobody tells you about
You can have permitted development and still commit a criminal offence
This sounds impossible and it is not. Solar panels on the roof of a dwelling are permitted development under Schedule 2, Part 14, Class A of the General Permitted Development Order, subject to the limits set out there. If the dwelling is listed, that same installation still needs listed building consent under section 7, because fixing panels to a listed roof is an alteration capable of affecting its character.
The reason is structural rather than accidental. The General Permitted Development Order is made under the Town and Country Planning Act. Listed building consent lives in a different Act. Neither instrument disapplies the other, and neither one mentions the other in the class you will be reading. So a perfectly honest installer can tell you, correctly, that you need no planning permission, and you can go to prison for the job they then carry out. Somebody has to join the two up, and it will not happen automatically.
Planning permission is not a defence to a building regulations breach
Nor the other way round. A planning approval says the council is content with what the work looks like and how it sits in its surroundings. It says nothing about whether the structure is adequate, whether the insulation meets Part L or whether the drainage is legal. Equally, a completion certificate from building control is not evidence that the work had planning permission.
These are usually different teams inside the same council, working to different statutes on different timescales, and in some areas they are different organisations altogether. Nobody in either team is checking that you have dealt with the other. That job is yours, or your builder’s, and it should be written into the quote rather than assumed. A quote that says which regimes the contractor has considered, and which they have not, is worth more than one that is silent on the question.
Your house
How to find out which of these applies to you
All of the above is the general law. Which parts of it apply to your house turns on facts about your particular building and your particular plot, so treat this as an explainer and confirm your own case with your local planning authority before anybody starts work. A pre-application enquiry or a duty planning officer call is free or cheap, it is quick, and it is the only answer that is actually about your house.
Before you make that call, gather four things. It makes the conversation much shorter.
- Is the building listed? Search the national list of listed buildings, or ask your council’s conservation team. Check the address either side of yours as well, because a terrace can be listed as a group and a curtilage structure can be listed without appearing in any entry of its own.
- Are you in a conservation area? Every local planning authority publishes a map of its conservation areas, and most publish a written appraisal for each one saying what the area’s character consists of. That appraisal is the document an officer will judge your roof against, and you can download it today.
- Is there an article 4 direction? This is the one almost nobody checks, and it is now easy. The government publishes a national dataset of article 4 direction areas searchable by address, covering thousands of directions from more than a hundred separate authorities. The page carries its own warning that the data may be incomplete, so treat a nil result as encouraging rather than conclusive and confirm it with the council.
- Are there conditions on an earlier planning permission? If your house is on an estate built in the last forty years, permitted development rights may have been removed by condition when the estate was approved. The council’s online planning register will have the original decision notice.
Those four checks take an evening and they settle most of the argument. What they will not settle is the building regulations question, because that turns on how much of the structure the work actually disturbs rather than on where the house sits. For that, ask the contractor to say in writing what the job involves down to the rafters, and then ask building control.
Next steps
What to do with all this before you accept a quote
In order, and none of it costs you anything.
- Run the four checks above on your own address. Listed, conservation area, article 4, planning conditions.
- Ask every contractor quoting the same question, in writing: which of the five regimes applies to this job, and who is responsible for dealing with each one. A good answer names them. A vague answer is information in itself.
- If the building is listed, or if any part of the work is demolition in a conservation area, stop and speak to the conservation officer before you accept any quote. Those are the two regimes where being wrong is criminal rather than expensive.
- If the work is notifiable to building control, agree before you start who is giving the notice and who ends up holding the completion certificate. It should be named in the quote.
- Keep every decision notice, certificate and email in one folder. The person who needs it most is the solicitor acting for whoever buys the house from you.
If it turns out you need none of the five, that is a real answer and a good one. Plenty of roofing, repointing and rendering work sits entirely outside all of this, and you should not let anybody sell you an application you do not need.
If you would like the job looked at before you decide, that is what we do. Thomas comes out, goes over the work himself, and puts in writing what he found, what it would take to put right and which permissions he thinks are in play. You can see the range of work on our roofing services and bricklaying and repointing pages, or ask for a site visit and we will come and look.
Questions
Questions we get asked about this
What is the difference between planning permission and building regulations?
Planning permission is about the effect of your work on everybody else: appearance, scale, overlooking, the character of the area. Building regulations are about performance and safety: structure, fire, damp, ventilation, insulation and drainage. They are separate systems with separate applications, and a job can need one, both or neither.
Do I still need to apply for conservation area consent?
Not in England. Conservation area consent was abolished on 1 October 2013 by section 63 of, and Schedule 17 to, the Enterprise and Regulatory Reform Act 2013. Demolition of a building in a conservation area now needs ordinary planning permission, and carrying it out without permission is a criminal offence under section 196D of the Town and Country Planning Act 1990. Wales kept conservation area consent until 4 November 2024.
Is permitted development the same as planning permission?
It is planning permission, granted to you in advance by the General Permitted Development Order rather than by an application. There is nothing to apply for. It only covers planning, though, so it says nothing about building regulations, listed building consent, party wall matters or the highway.
Does listed building consent only apply to big alterations?
No. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 sets no size threshold at all. The test is whether the works affect the character of the building as one of special architectural or historic interest, so a small job in the wrong material can need consent when a larger like-for-like repair does not.
What happens if I do the work without the permission I needed?
It depends which regime. Missing planning permission usually means an enforcement notice or a retrospective application. Missing building control usually means putting the work right and a stalled sale later. Missing listed building consent, or demolishing in a conservation area without permission, is a criminal offence carrying up to two years on indictment.
