Permission was granted
Read the decision notice, approved drawings and every condition. Check that the permission remains usable, that work matches the approval and that pre-commencement or continuing conditions have been addressed.
UK planning and mortgage guide
Can you get a mortgage without planning permission?
Potentially—but first establish whether permission was actually required, what the property may lawfully be used as, whether any conditions or enforcement risk remain, and whether the valuer, solicitor and lender can accept the property as security.

Quick answer
A missing planning document does not produce one automatic mortgage answer
A mortgage may still be possible where planning permission is absent, but only after the underlying position is understood. The work may not have needed an application; it may have been permitted development; the present use may be lawful; or there may be an unresolved breach that affects value, marketability, occupation or enforcement risk.
The lender does not decide the planning position in isolation. The valuer considers the property and assumptions, the solicitor investigates title and consents, and the lender applies its security and product criteria. A workable route for one property is not a precedent for another.
Planning permission and building regulations are different. A project may need one, both or neither, and other consent may still apply. Do not treat a planning approval as evidence that the construction itself was approved or completed correctly.
Identify the legal position
What does “no planning permission” actually mean?
The answer changes according to the work, use, location, date and UK nation. Ask the local planning authority or an appropriately qualified planning professional about the specific property rather than relying on a generic rule.
Permitted development
Some work or changes may be permitted without a full planning application, subject to limits, conditions and sometimes prior approval. Rights can be restricted, including by an Article 4 direction in England.
Lawful development evidence
In England, a lawful development certificate can provide formal confirmation that a proposed or existing development is lawful for planning purposes. It does not replace building regulations, listed-building consent or other regimes.
Permission was required but is missing
This may create a legal, valuation and marketability issue. The appropriate response could involve further evidence, professional advice, an application or another legal solution; none should be assumed before the facts are reviewed.
Consent exists but the work differs
A decision notice is not enough if the property was built or used differently. Compare the completed position with approved plans, conditions and certificates, then establish whether the difference is material.
Enforcement or council contact
An enforcement notice, active investigation, complaint or unresolved breach can materially change the lender and legal position. Give the broker, solicitor and lender complete information at the outset.
UK-wide guide, local rules. Planning systems and terminology differ across England, Scotland, Wales and Northern Ireland. The relevant local authority and nation-specific guidance should be checked for the property concerned.
Security must remain acceptable
How can planning status affect a mortgage decision?
Published residential conveyancing instructions in the UK Finance Lenders’ Handbook show why planning and building-regulations questions matter: necessary consents, current use, breaches, enforcement, restrictions, value and future marketability may all need investigation or reporting.
| Question | Why it matters | What may help the review |
|---|---|---|
| Is the present use lawful? | A property described or valued as a house, flat, HMO, shop or mixed-use building must be capable of the intended occupation and mortgage route. | Planning history, searches, decision notices, use evidence and appropriate professional confirmation. |
| Does the physical property match the records? | An extension, conversion, subdivision or new unit can change value, saleability and the valuer’s assumptions. | Approved drawings, measurements, completion documents, survey and an explanation of any difference. |
| Could enforcement affect the security? | Required alteration, restricted use or removal could reduce value or prevent the intended use. | Solicitor and planning advice, council records, certificates and a clearly agreed resolution route. |
| Are planning conditions material? | Occupancy, use, parking, access, affordable-housing, agricultural or other restrictions may affect who can use or buy the property. | The complete permission, section 106 or equivalent documents, evidence of discharge and lender review. |
| Is the project complete and habitable? | A standard mortgage may not fit a property needing material work, conversion or regularisation before normal occupation. | Scope of work, costs, permissions, programme, cash contribution and a credible exit to a later mortgage. |
Do not assume retrospective permission or indemnity insurance will solve the case. Permission can be refused, a certificate requires evidence, policy terms have limits and proposed contact with an authority can affect legal options. Let the solicitor, planning professional and lender guide the sequence.
Match the solution to the facts
Common planning-permission mortgage situations
The same phrase can describe very different risks. These examples are review routes, not promises that a lender will accept the property.
Extension, loft conversion or conservatory
Establish when the work was completed, whether an application was required, whether permitted-development limits were met and whether building-control or other evidence exists. A valuer may also consider construction quality and marketability.
House converted into flats or an HMO
Planning, building control, licensing, tenancy and title questions can overlap but are not interchangeable. Confirm the lawful number and type of units and identify the correct residential, buy-to-let, HMO or commercial route.
Listed building, conservation area or Article 4 area
Normal permitted-development assumptions may not apply, and listed-building consent can be separate from planning permission. Obtain property-specific advice before work, regularisation or a mortgage application.
Land with planning permission
Permission may improve clarity but does not turn land into a normal house-mortgage security. Review the land, access, services, conditions, implementation position, build costs, borrower cash and development exit together.
Land without planning permission
Funding may be considered against the land in its present state rather than an assumed development value. Do not pay a residential-development price on the expectation that permission, value or later finance is guaranteed.
Self-build, renovation or development
Where substantial work is planned, the immediate facility may be self-build, renovation, bridging or development finance. A later mortgage is a separate exit that must be supportable at completion.
Before exchange or commitment
What should you do if you are buying a property with a planning concern?
Resolve the planning, valuation, legal and funding assumptions together. A finance indication based on an incomplete description is not enough.
Describe the property accurately
Provide the current use, layout, units, work completed, proposed work, occupation and the purchase or auction deadline.
Collect the planning record
Obtain the decision notice, drawings, conditions, certificates, search results, council correspondence and dates of relevant work or use.
Use the right professionals
Ask the solicitor and, where needed, a planning consultant, surveyor, architect or building-control specialist to address their own part of the risk.
Confirm the finance route
Only proceed when the lender is assessing the correct property and use, the cash requirement is clear and any conditions can realistically be met.
Auction or fixed completion deadline? Do not rely on an assumed fast mortgage, future planning approval or a generic agreement in principle. Legal, valuation, planning and lender questions can continue after an initial credit or affordability check.
Build one evidence pack

Already own the property?
What if you discover the issue after purchase?
- Do not conceal the issue on a sale, remortgage or further-advance application.
- Gather the conveyancing file, planning history, plans, invoices, photographs and dates.
- Ask a solicitor and planning professional which facts must be verified before contacting the authority or arranging insurance.
- If your mortgage terms or proposed work may be affected, obtain appropriate lender and professional advice.
- Allow time: regularisation, evidence, valuation and legal review are not guaranteed to complete quickly.
What can Count Ready help with?
Count Ready can help identify the mortgage or property-finance questions, explain the evidence a potential lender is likely to need and compare appropriate routes once the planning and legal position is sufficiently clear.
We cannot grant planning permission, certify lawfulness, give a valuation or replace legal, planning, building-control or surveying advice. Where a specialist conclusion is needed, obtain it before treating the case as lender-ready.
A good outcome is not always “find a more flexible lender”. It may be to correct the description, obtain missing evidence, change the proposed work, resolve a condition, use short-term finance before a later mortgage, or avoid an unsuitable purchase.
Free initial review
Ask Count Ready to review the mortgage route
Tell us the property address, current and intended use, work completed or proposed, planning evidence, price or value, borrowing required, deposit or equity and deadline. Mention any council, legal, valuation or lender concern at the start.
Do not send passwords or original identity documents through an initial enquiry.
Broker fee transparency: The initial review is free. Count Ready usually charges a fee of £595 on mortgage offer, agreed before chargeable work begins. Count Ready may also receive commission from the lender.
Planning-permission mortgage FAQs
Answers to common borrower questions
Can you get a mortgage without planning permission?
Potentially. First establish whether permission was required and whether the present property and use are lawful. The valuer, solicitor and lender will then consider the evidence, value, marketability, enforcement risk and mortgage criteria. A missing document does not lead to one automatic answer.
Can you get a mortgage on land with planning permission?
Potentially, but land is not automatically suitable for a normal residential mortgage. The finance review may include the permission, conditions, implementation position, access, services, site value, build costs, borrower cash, experience and exit. Land finance, bridging, self-build or development finance may be more appropriate.
Can you get a mortgage on land without planning permission?
Potentially, with the land assessed in its current state and use rather than at an assumed future residential-development value. The borrower should not rely on future planning consent, value or refinance being granted. Commercial land finance may be the relevant route.
Is planning permission the same as building-regulations approval?
No. Planning controls the development and use of land, while building regulations set standards for design and construction. A project may need one, both or neither, and listed-building, licensing, environmental or other consent may also apply.
What is permitted development?
Permitted development rights grant planning permission for specified development without a full planning application, subject to the applicable limits and conditions. Rights vary by nation and property type, can require prior approval and may be restricted locally. Obtain property-specific confirmation where the position matters to a transaction.
What is a lawful development certificate?
In England, a local planning authority may grant a certificate confirming that an existing or proposed use or development is lawful for planning purposes when the relevant legal and evidence tests are met. It is not a substitute for building regulations, listed-building consent or other legal requirements.
Will retrospective planning permission guarantee a mortgage?
No. An application may be refused and a later approval does not guarantee the valuation, legal title, construction evidence, affordability or lender criteria. Agree the planning and mortgage sequence with the relevant professionals before relying on this route.
Will planning indemnity insurance solve a missing-permission problem?
Not automatically. A policy may have eligibility conditions, exclusions and limited cover, and it does not prove construction quality or make an unlawful use suitable for a lender. The solicitor and lender must decide whether insurance is available and acceptable for the facts.
Can I remortgage after an extension or conversion without planning records?
Potentially. Provide the date and description of the work, planning history, approved plans or lawful-development evidence, building-control records and any professional reports. The valuer, solicitor and lender will decide whether further evidence or action is required.
How long does a planning-permission mortgage take?
There is no reliable universal timescale. Searches, valuation, planning advice, certificates, building-control evidence, lender questions, legal review and third parties can all affect timing. Start before a contractual deadline and do not assume an agreement in principle resolves the property issue.
