Do I need landlord consent and building regulations approvals before applying?

The short answer — what lenders expect at application vs drawdown

In most cases, you do not need full landlord consent or Building Regulations approvals to start an enquiry or get an initial Decision in Principle. However, you should expect lenders or brokers to make any offer “subject to” receiving the correct consents before funds are released. If your project involves altering a leased or owned premises, you will usually need evidence of permissions prior to drawdown and before works begin.

This matters because approvals can take weeks, and funding decisions often hinge on them. Starting applications while consents are in progress is common, but not having them ready when asked can delay completion or force a re-assessment of risk. The smarter approach is to plan approvals early, so finance and build timelines stay aligned.

At Best Business Loans, we don’t lend directly, but we help you reach providers who are active in your sector and understand fit-outs, refurbishments and upgrades. Our role is to save you time, set realistic expectations, and connect you with lenders or brokers who can support your plan. That includes clarifying what consents you’ll likely need for your type of work.

What this means for your timeline

Week 0–2: Finalise scope of works, check your lease, speak with your landlord and Building Control.
Week 1–3: Submit your Quick Quote and obtain an initial eligibility view or Decision in Principle.
Week 2–8: Progress landlord consent (often via a Licence to Alter) and Building Regulations approval.
Week 4–10: Underwriting and due diligence, with consents provided for drawdown.

Timescales vary by landlord, local authority, and complexity of works. Build contingencies into your plan to avoid last-minute delays.

Landlord consent — when you need it and what it looks like

If you occupy on a lease, most alterations require written landlord consent, typically via a Licence to Alter. Your lease will set out what is permitted, what needs consent, and any reinstatement obligations at lease end. Structural works, changes to services, ventilation, signage, extraction, or alterations visible from outside nearly always need consent.

Even “non-structural” fit-outs can still require consent if they affect building fabric, fire protection, or mechanical and electrical systems. Lenders assess whether your planned works are lawful and whether the landlord can demand removal later, which could undermine the value or usefulness of funded assets. A clear, written consent reduces that risk.

You will normally be asked for a scope of works, drawings, method statements, and contractor details. The landlord may instruct a surveyor or managing agent, and you may be liable for their reasonable costs. Factor those costs and time into your budget and schedule.

Typical contents of a Licence to Alter

A description of the permitted works with referenced drawings and specifications.
Conditions about working hours, noise, and site access to protect other occupiers.
Requirements to comply with Building Regulations, fire safety and relevant codes.
Obligation to reinstate at lease end, unless otherwise agreed.
Evidence of insurances and contractor competence, and sometimes warranties.
Provisions for inspection and sign-off by the landlord or their surveyor.

Some landlords also require collateral warranties or a schedule of condition. These protect the landlord’s asset and clarify responsibilities if things go wrong.

If your landlord refuses or sets conditions

Many leases say consent cannot be unreasonably withheld for qualifying works, but what’s “reasonable” depends on the lease and building. If you face conditions, assess cost, time and practicality before committing to finance. You could amend the design to address landlord concerns or negotiate terms around reinstatement or signage.

A clear paper trail is vital if consent is delayed, because lenders may time-limit offers or change terms if the project stalls. If consent is refused and the project cannot proceed, you should pause any finance process to avoid unnecessary fees. Always take independent legal advice on your lease obligations before starting works.

Building Regulations, planning and other permissions explained

Building Regulations are about safety, accessibility, energy efficiency and standards of construction. Many interior refurbishments, new partitions, fire doors, ventilation, extraction, electrical works, or changes to means of escape require Building Control approval. You can apply via your local authority or an approved inspector.

Planning permission is different and relates to use, external appearance, signage, and development control. You might not need planning for internal works, but you could need it for change of use, new shopfronts, external plant, flues, or signage. Listed buildings and conservation areas involve extra controls and separate Listed Building Consent.

Separate approvals may be needed for licensing (e.g., alcohol, late-night refreshment), highways, or environmental health. Fire safety duties under the Regulatory Reform (Fire Safety) Order apply to most non-domestic premises and require a current fire risk assessment. Coordinate these checks early so lenders see a credible, compliant plan.

Which works usually need Building Regulations approval?

New or altered partitions, ceilings, or doors on escape routes (Part B – fire safety).
Changes to accessibility, ramps, WCs, or layout affecting circulation (Part M – access).
New HVAC, extraction, or ventilation systems (Part F – ventilation).
Electrical works in commercial premises, tested and certified by a competent person.
Thermal upgrades, glazing changes, or lighting design affecting energy efficiency (Part L).
Any structural changes, mezzanines, or load-bearing alterations.

On completion, Building Control should issue a Completion Certificate. Lenders often require this, or staged sign-offs, before releasing final tranches or confirming project completion.

Special cases: Scotland, Wales and Northern Ireland

Regulatory frameworks differ across the UK. Scotland uses a Building Warrant system, and terminology varies in Wales and Northern Ireland. The principles are similar, but processes and documents differ, so take local professional advice.

If you trade across multiple sites in different nations, be prepared for different approval timelines. Lenders understand these differences but will still expect compliant documentation for each jurisdiction. Plan for that in your roll-out or refurbishment schedule.

How approvals affect funding — what providers will ask for

Most lenders can issue an initial eligibility view without final approvals, based on your business profile, credit strength, and project summary. However, formal acceptance and drawdown typically carry conditions precedent. These conditions often include landlord consent, Building Regulations approval, insurance, and evidence of contractor competence.

If funding is for furniture, fixtures and equipment, some items are “tenant’s fixtures” and removable, while others become part of the building. Lenders may treat built-in items differently because removal risk and landlord rights vary. Your asset schedule should clearly separate removable assets from integrated works with proper valuations.

Providers funding fit-outs may prefer staged drawdowns tied to milestones. Without evidence of approvals and sign-offs at each stage, release of funds can be paused. Clear documentation keeps the money flowing and the project on programme.

Documents checklist for a smoother approval

Lease, any deeds of variation, and the draft or executed Licence to Alter (if applicable).
Scope of works, drawings, specifications, and contractor quotes or JCT contracts.
Evidence of Building Control engagement and, later, completion or staged sign-offs.
Planning or Listed Building permissions, or confirmation they’re not required.
Insurance details: public liability, contractors’ all-risks, and contents where relevant.
Certificates: electrical, gas, fire alarm/emergency lighting commissioning, F-Gas, etc.
Fire risk assessment and, for food/hospitality, environmental health compliance.
Programme with milestones and cash flow, including contingencies.

If your project is a refurbishment, shopfit or clinic/lab upgrade, learn how funding can be structured in our fit-out finance overview. See our page on fit-out finance to understand typical terms and asset types that can be included.

Common pitfalls that delay funding

Starting works before securing landlord consent, triggering breaches of lease.
Assuming internal works don’t need Building Control, then failing inspections.
Unclear scopes, missing drawings, or late contractor appointments.
No contingency budget for landlord surveyor fees or additional compliance costs.
Mixing removable assets with integrated fabric without a clear asset schedule.
Underestimating lead times for planning, signage or listed consent.

Avoiding these issues increases your chance of a timely decision and on-time drawdown. It also reduces the risk of cost overruns that strain cash flow mid-project.

FAQs

Can I apply for finance before I have landlord consent?

Yes, you can apply and seek a Decision in Principle while consent is in progress. Most providers will require a signed Licence to Alter or equivalent before releasing funds for works. Applying early helps you align approvals with funding timelines.

Do I always need Building Regulations approval for internal works?

Not always, but many internal alterations do require approval, especially where fire safety, structure, services, ventilation or accessibility are affected. Always check with Building Control or an approved inspector before you start. Lenders may ask for evidence of compliance and completion certificates.

What if my landlord refuses consent?

If consent is refused, you may need to revise your design or pause the project. Starting without consent risks breach of lease and enforcement, which can void funding offers. Seek legal advice to understand your position and options.

How long do approvals take?

Landlord consent can take 2–8 weeks, and more for complex or multi-tenant buildings. Building Regulations approval can be quicker if you use an approved inspector, but timescales vary by scope. Always plan contingencies of several weeks to protect your programme.

Will a lender fund items that become part of the landlord’s building?

Some will, but terms can differ because of removal and ownership risks. Expect closer scrutiny on integrated items and landlord rights. A clear asset schedule separating removable FF&E from integrated works helps underwriting.

Can I release funds in stages?

Many providers offer staged drawdowns tied to milestones and sign-offs. This can suit larger fit-outs and reduce interest on undrawn funds. You will need robust documentation at each stage to trigger release.
