Do You Need Planning Permission for Airbnb in Milton Keynes? 2025 Guide

The Short Answer

In most cases, you do not need planning permission to short-let your property in Milton Keynes — provided you stay within certain limits. But there are important conditions, and the regulatory landscape changed significantly in 2025. Here's exactly where things stand.

Planning Permission for Short-Let in England (2025)

In England, the planning rules for short-lets depend on the type of property and how frequently you let it:

Your main home (where you also live): Renting out rooms or the whole property while you're away generally doesn't require planning permission regardless of the number of nights — it's considered a continuation of residential use.

A second property or investment property: Under current English planning rules, short-letting a property you don't live in for fewer than 90 nights per year is generally considered permitted development — no planning application required. Exceeding 90 nights may require a Change of Use application to Milton Keynes Council.

Important note: This is a general guide, not legal advice. Planning rules can vary locally and change over time. Grid Stays guides every new client through the current requirements during onboarding, but we recommend checking directly with Milton Keynes City Council's planning department if you have any doubt.

The New Short-Term Let Register (2025)

The UK government introduced a mandatory national Short-Term Let Register in England in 2025. This means:

• All short-let hosts in England must register before listing their property
• Registration is with your local authority (Milton Keynes City Council)
• Platforms like Airbnb and Booking.com are required to display registration numbers
• Failure to register can result in fines

Grid Stays handles registration as part of our standard onboarding process. If you're self-managing, you'll need to register independently before going live.

Mortgage Considerations

This is one of the most commonly overlooked issues for new short-let landlords in MK. Most standard buy-to-let mortgages explicitly prohibit short-let use.

Before listing your property on Airbnb, check your mortgage terms and conditions carefully. If your mortgage doesn't permit short-let use, you must either:

• Notify your lender and request permission (some will grant it, many won't)
• Remortgage to a product that explicitly permits short-let or holiday let use
• Use a specialist short-let mortgage product

A growing number of lenders now offer specific short-let mortgage products, and mortgage brokers specialising in this area can find you competitive rates. Grid Stays can refer you to trusted brokers who specialise in short-let mortgages for MK landlords.

Short-Let Insurance Requirements

Standard buildings and contents insurance will not cover short-let activity. Most policies explicitly exclude commercial use, and letting your property to paying guests typically constitutes commercial use.

You need a specialist short-let or holiday let insurance policy that covers:

• Guest liability (if a guest injures themselves in your property)
• Guest damage (deliberate or accidental)
• Loss of income during unplanned void periods
• Contents and buildings on a commercial use basis

Safety Certificate Requirements

Before your first guest checks in, you must have:

• Gas Safety Certificate: Required annually if the property has gas appliances
• Electrical Installation Condition Report (EICR): Required every 5 years
• Working smoke alarms: On every floor of the property
• Carbon monoxide alarm: In rooms with solid fuel appliances
• Energy Performance Certificate (EPC): Required for marketing the property

Grid Stays audits all safety certificates during onboarding and can arrange any missing certificates via our Urban Gate maintenance team at cost price with no markup.

Short-Let Tax in 2025

Short-let income is taxable as rental income in the UK. The important change in 2025 is the abolition of the Furnished Holiday Letting (FHL) tax regime, which previously gave short-let landlords more favourable treatment on mortgage interest relief and capital allowances.

Since April 2025, short-let properties are taxed as standard rental income. However, there may still be advantages through the Property Income Allowance (£1,000/year) and, if you live in the property, the Rent-a-Room relief (up to £7,500/year tax-free).

We strongly recommend speaking to a property tax accountant before switching to short-let. Grid Stays can refer you to accountants specialising in property landlord tax in the MK area.
