Renting Out Your Home While Working Abroad: Tax and Mortgage Rules 2026/27
What UK homeowners moving abroad for work need to know about letting their home in 2026/27 — consent to let, non-resident landlord tax, and mortgage implications.
The three separate permissions you need
Moving abroad for work and letting out your UK home while you're away involves three distinct approvals that are easy to overlook amid the logistics of an international move: your mortgage lender's consent, HMRC's non-resident landlord registration, and appropriate landlord insurance. Missing any one of these creates real financial and legal risk.

Most people in this situation start with consent to let — temporary permission from their existing residential lender to rent out the property, usually granted for a defined period (commonly 12 months, sometimes renewable), often with a modest admin fee and a small interest rate increase. This suits genuinely temporary postings abroad, since you keep your existing residential mortgage rather than remortgaging onto a full buy-to-let product.
If your time abroad is likely to be longer-term or indefinite, switching to a dedicated buy-to-let mortgage may be more appropriate — buy-to-let products are underwritten around rental income rather than your personal income, and don't carry consent-to-let's typical time limits.
Registering as a non-resident landlord
If you become non-resident for UK tax purposes while letting a UK property, register under the Non-Resident Landlord Scheme (NRLS) using form NRL1. Once approved:
- Your letting agent (or tenant, if there's no agent) can pay you rent gross, without deducting tax
- You declare the rental income and pay any tax owed through your annual Self Assessment return
Without NRLS approval, your agent or tenant is legally required to deduct basic rate tax (20%) from the rent before paying you — you can reclaim any overpayment via Self Assessment, but this unnecessarily ties up your cash flow while you're abroad.
Worked example: rental income and tax while working abroad
Situation: A homeowner moves to Dubai for a two-year work posting and lets their UK home for £1,500/month (£18,000/year), while remaining non-resident for UK tax purposes.
NRLS registered: Rent paid gross by the letting agent.
Allowable expenses: Letting agent management fee (12%, £2,160), landlord insurance (£350), mortgage interest (deductible via the 20% tax credit under current rules, not as a direct expense), general maintenance (£600).
Taxable profit before mortgage interest credit: £18,000 − £2,160 − £350 − £600 = £14,890
Tax: As a non-resident, they still get the UK Personal Allowance if they're a British citizen or from certain qualifying countries (£12,570), so tax is due on £14,890 − £12,570 = £2,320 at 20% = £464, before applying the 20% mortgage interest tax credit which further reduces the bill if there's mortgage interest to claim.

- Contact your mortgage lender early to request consent to let, or discuss switching to a buy-to-let product if your move is longer-term.
- Submit NRLS form NRL1 to HMRC before or shortly after you become non-resident.
- Arrange landlord insurance — standard home insurance won't cover a tenanted property.
- Instruct a fully managed letting agent if you won't be able to handle maintenance and tenant issues remotely.
- Keep records of rental income and expenses for your annual Self Assessment return, even while abroad.
- Consider the Capital Gains Tax position if you might sell the property while it's let or after returning, since the letting period can affect the calculation.
The bottom line
Renting out your home while working abroad is entirely achievable and common, but it requires proactive paperwork on three fronts — mortgage, tax registration, and insurance — before your tenant moves in, not after. Getting NRLS approval in particular is a small piece of admin that meaningfully improves your cash flow for the whole time you're away.
Frequently asked questions
Can I just rent out my home when I move abroad without telling my mortgage lender?
No — this would breach your mortgage terms, since a standard residential mortgage doesn't permit letting the property. You need to get 'consent to let' from your lender, or switch to a buy-to-let mortgage, before letting the property while you're abroad.
What is consent to let and how does it differ from a full buy-to-let mortgage?
Consent to let is temporary permission from your existing residential mortgage lender to let the property, usually for a limited period (often 12 months, sometimes renewable), often at a slightly higher interest rate or with a small admin fee, without switching the whole mortgage to a buy-to-let product. It's designed for temporary situations like working abroad, rather than becoming a long-term landlord.
Do I need to register as a non-resident landlord with HMRC?
Yes, if you'll be non-resident in the UK for tax purposes and rent out a UK property, you should register under the Non-Resident Landlord Scheme (NRLS). Without approval, your letting agent or tenant is required to deduct basic rate tax from the rent before paying you, even if your actual tax liability would be lower after allowable expenses.
Do I still pay UK tax on rental income if I'm working and living abroad?
Yes — UK rental income remains taxable in the UK regardless of your residency status, since it's UK-source income. You'll still need to complete a Self Assessment tax return each year declaring the rental income and any allowable expenses, even while non-resident.
How does NRLS approval affect how my tenant or agent pays me?
If HMRC approves your NRLS application, your letting agent or tenant can pay you the rent gross (without tax deducted), and you account for tax through your annual Self Assessment return instead. Without approval, 20% basic rate tax is deducted at source, which you can later reclaim if your actual liability is lower, but this ties up cash flow unnecessarily.
Does working abroad change my Capital Gains Tax position if I sell the property later?
Potentially yes. If you've genuinely lived in the property as your main home before letting it, you may still get some Private Residence Relief for the period you lived there, but the letting period while abroad is generally taxable on any gain, and non-resident CGT rules require reporting and paying within 60 days of completion regardless of residency.
Will my home insurance still be valid once it's let and I'm abroad?
Standard homeowner's insurance typically doesn't cover a let property — you'll need landlord insurance, which covers buildings, and often liability and loss-of-rent risks specific to a rented property, rather than an owner-occupied one.
What happens if I come back to the UK before my posting abroad ends?
You'll need to give your tenant appropriate notice under the tenancy agreement to regain possession — this isn't automatic just because you return, and the notice period depends on the type of tenancy and where in the UK the property is located, so plan the end of any fixed-term tenancy around your expected return date where possible.
Should I use a letting agent while I'm abroad, or manage the property myself?
Most people working abroad use a fully managed letting agent service, given the practical difficulty of handling maintenance issues, tenant queries, and legal compliance (gas safety checks, deposit protection, right to rent checks) remotely from a different time zone. The management fee (commonly 10%-15% of rent) is a deductible expense against your rental income.
Does the £1,000 property allowance apply to non-resident landlords?
Yes, the £1,000 tax-free property allowance is available to UK and non-resident landlords alike, though for most people letting out their main home while working abroad, the rental income will exceed £1,000 and actual expenses (mortgage interest relief via the tax credit, management fees, insurance, etc.) will usually give a better tax outcome than the flat allowance.
