What is the Rent a Room scheme and how does it work in the UK

If you own or rent a home with a spare room and want to generate additional income, the Rent a Room scheme is one of the most tax-efficient options available to UK residents. It allows you to earn up to seven thousand five hundred pounds per year from renting a furnished room in your home without paying any tax on that income.

How the scheme works

The Rent a Room scheme is automatic. You do not need to apply for it or register. If you earn seven thousand five hundred pounds or less from renting a room in your main home in a tax year, you simply do not pay tax on that income. You do not need to declare it on a Self Assessment return unless HMRC ask you to or you already file one for other reasons.

If you earn more than seven thousand five hundred pounds from renting a room, you need to declare the income on a tax return. At that point you have two options: pay tax on the excess above the threshold, or opt out of the scheme and pay tax on your profit after deducting allowable expenses in the usual way. Which approach is more tax-efficient depends on your actual income and costs.

Who can use it

The scheme applies to owner-occupiers and tenants alike, as long as you rent out a furnished room in the home you actually live in. You cannot use it for a property you rent out but do not live in yourself. If your home is jointly owned or rented, the seven thousand five hundred pound threshold is divided between the joint owners, giving each person a threshold of three thousand seven hundred and fifty pounds.

What to think about before renting a room

Before listing a room, check whether your mortgage or tenancy agreement allows it. Most mortgage lenders permit taking in a lodger, but it is worth confirming. If you are renting your home, you need your landlord's permission to sublet a room.

You should also consider whether your home insurance covers having a lodger. Some policies do not include this automatically and need to be updated. The cost of the additional cover is usually modest relative to the income generated.

Setting a sensible rent

Room rental prices vary enormously by location. Checking what rooms in your area are currently listed for on SpareRoom, Rightmove, or local Facebook groups gives you a realistic sense of the market rate. Setting rent at or slightly below market rate for a good quality room tends to attract reliable tenants faster and keep them longer, which reduces the cost and disruption of finding new ones.

Using a lodger agreement

A written lodger agreement sets out the terms — rent, notice periods, house rules, what is included — and protects both parties. Because you are a resident landlord, the legal protections for lodgers are different to those for full tenants, which makes informal arrangements more common. But a simple written agreement prevents misunderstandings about what was agreed.
