Tenant Permission to Make Alterations in Wales

Tenants in Wales often want to improve or personalise their homes, but making alterations can raise questions about consent, legal obligations and future liabilities. This guide explains when you typically need landlord permission, what to include in a written request, and the practical steps if consent is refused or withdrawn. It covers basic differences between minor decorative work and structural changes, how building regulations or planning permission can affect a project, and how the First-tier Tribunal or local authorities may become involved. Advice is aimed at renters and tenants without legal training, using plain language and real-world examples so you can take informed steps and protect your deposit and tenancy rights in Wales.

When do tenants need permission?

Most tenancy agreements set out whether tenants may make changes. If your contract says you must get the landlord's written consent before making alterations, follow that clause. Structural work, changes to heating or plumbing, and works affecting fire safety almost always need permission and may also require building regulations or planning permission. See the Housing Act 1988 for the legal context and landlord/tenant duties Housing Act 1988^[1].

Common types of alterations

• Minor decoration (painting, removable wallpaper, hanging pictures).
• Maintenance-style changes (replacing a tap, fixing a shelf) that affect habitability or services.
• Installation of fixtures that require landlord consent (built-in wardrobes, new kitchen units).
• Changes affecting safety, ventilation or fire precautions (new heated appliances, blocked vents).

How to ask your landlord for consent

Put the request in writing and keep a record. Clearly describe the work, include timescales, who will carry out the work, and whether you will restore the property at the end of the tenancy. Where appropriate, attach photos, diagrams and a short schedule of works. If the work might need building control or planning permission, say so and offer to provide copies of any approvals.

• Write a clear request with dates and a description of the proposed work.
• Attach photos, measurements and quotes as evidence of what you will do.
• Propose reasonable times for the work and any inspections by the landlord.
• Ask for written consent and keep a signed or emailed copy.

When you may need official approvals

Some alterations go beyond the tenancy and require building regulations approval or planning permission. Check GOV.UK guidance on planning and building control before starting; applying for planning permission is usually done through your local planning authority on GOV.UK Apply for planning permission.

What if the landlord refuses or does not respond?

If the landlord refuses a reasonable request, or fails to respond within a reasonable time, you should:

• Save all correspondence and evidence of your request and any replies.
• Try a phone call to follow up, then confirm the outcome in writing.
• If you cannot resolve the dispute, you may be able to apply to the First-tier Tribunal (Property Chamber) to decide consent or compensation; see the tribunal guidance on GOV.UK First-tier Tribunal (Property Chamber)^[2].

Consequences of unauthorised alterations

Carrying out work without permission risks a landlord requiring reinstatement, deducting costs from your deposit, or seeking damages. In serious cases (unsafe electrics, structural changes) the landlord can take stronger action. Always document the state of the property before and after any change so you can show the condition and who did the work.

Official forms and practical examples

There is no single, universal "permission" form for tenants; consent is usually a written or signed agreement between tenant and landlord. Where a formal application is needed you might use:

• Tribunal application: use the guidance and any prescribed application process on the First-tier Tribunal (Property Chamber) page when asking the tribunal to resolve a consent dispute. Example: if your landlord refuses reasonable consent for a disability adaptation, you can apply to the tribunal for a decision.
• Planning permission application: when external or structural changes need local authority consent, apply via GOV.UK. Example: installing a new external door that alters the building facade.
• Building regulations submission: where the work affects structure, fire safety or services you must notify building control; local authority processes are used to submit plans and inspections. Example: rewiring or altering load-bearing walls.

FAQ

Do I always need permission for small jobs like hanging shelves?

Not always; many landlords allow minor, non-permanent changes, but check your tenancy agreement and always confirm in writing to avoid disputes.

Can a landlord refuse consent unreasonably?

Landlords should not act unreasonably, but what counts as reasonable depends on tenancy terms, safety and property condition; if you disagree you can seek independent resolution through a tribunal or mediation.

What if I need an adaptation for a disability?

You should explain the medical need and request consent in writing; if consent is refused you may have additional protections and can ask a tribunal to consider the case.

How-To

1. Check your tenancy agreement for alteration clauses and any required notice provisions.
2. Draft a written request that describes the work, includes photos and timelines, and proposes who will do the work.
3. Send the request, agree a reasonable timetable for the work and for any landlord inspections.
4. Obtain written consent (email or signed letter) before starting; keep a copy.
5. If consent is refused, gather evidence and consider applying to the First-tier Tribunal or seeking mediation.

Key Takeaways

• Always check your tenancy agreement and get written consent for alterations.
• Document proposals with photos, quotes and a schedule before starting work.
• If you cannot agree, the First-tier Tribunal can resolve disputes about consent and compensation.
