Yes, a bereaved tenant can sometimes take in a lodger to help cover the rent — but only after four things have been settled, and moving someone into the spare room before you have checked them can cost you the home you are trying to keep. The four are: what your tenancy actually allows, whether the landlord will consent, what a lodger does to your benefits, and the tax on what the lodger pays you. Get those right and a lodger can be the difference between staying and moving. Get them wrong and you can breach the tenancy, lose benefit you were relying on, or hand a stranger the run of a home you are still grieving in.

It is a common thought after a partner has died, and a reasonable one. The rent was built for two incomes and there is now one, the spare room is sitting empty, and a lodger looks like an obvious way to bridge the gap without leaving. None of that is wrong. It simply needs checking in a particular order, because the first of the four can stop the whole idea dead before the others matter at all.

At a glance

  • Whether you can take in a lodger depends first on your tenancy: most private agreements forbid it or require the landlord's written consent, while many social tenants can, once they tell the landlord.
  • Taking a lodger without the permission your tenancy requires can breach it and give the landlord a ground for possession.
  • Under Universal Credit a lodger's payments are usually ignored as income, but the lodger does not count as needing a bedroom, so a social tenant can still face a spare-room deduction.
  • The Rent a Room scheme lets you receive a set amount each year tax free from a lodger in your own home; above it you have to tell HMRC.
  • A lodger ends your single-person council tax discount and puts a stranger into a grieving home — weigh the money against both.

The short answer: check four things before anyone moves in

A lodger is someone who lives in your home and shares living space with you — they rent a room, not the property, and you keep the run of the place. That is different from a subtenant, who takes exclusive possession of part of the home and has far more protection, and the distinction matters because tenancies treat the two very differently. Almost everything in this guide is about a lodger in the ordinary sense: a person in the spare room who shares your kitchen and bathroom.

The four checks are not equally weighted. The first — does your tenancy allow it — is a gate: if the answer is no and stays no, the rest is academic. The second, third and fourth shape whether a lodger is actually worth it once benefits and tax are taken into account. Work through them in order, because it is dispiriting to research the tax position of an arrangement your tenancy was never going to permit. The whole question sits inside the wider set of decisions a bereaved renter faces, which we set out in our guide to renting and tenancy after a death.

First: does your tenancy even allow a lodger?

This turns almost entirely on whether you rent privately or from a social landlord.

If you are a private tenant on an assured shorthold tenancy, the default is unhelpful. A great many private agreements either prohibit taking in a lodger outright or allow it only with the landlord's written consent, and unlike some other requests there is no general legal rule forcing a private landlord to say yes. Read your agreement for a clause on lodgers, sub-letting, or "parting with possession" before you do anything else.

If you are a social tenant — renting from a council or a housing association — the position is usually more generous. Secure council tenants in England and Wales generally have the right to take in a lodger, and typically need only to tell the landlord rather than ask permission, although you should still notify them. Housing association tenants often can too, but this is more likely to be subject to the tenancy agreement and to consent, so check yours. The reason to notify even where you have the right is that a lodger can affect your housing benefit and your council tax, and the landlord and council need to know.

The warning that applies to everyone: doing this without the permission your tenancy requires is not a technicality. Taking in a lodger in breach of the agreement can be a breach of tenancy in its own right, and it can give a landlord a ground to seek possession. The downside of asking first is a possible no. The downside of not asking can be losing the home.

Second: getting the landlord's permission

Where consent is needed, ask for it in writing, and ask well. A short, specific request — who the lodger would be, that they would share your living space rather than take a separate part of the home, that you would remain the tenant responsible for the property — is far more likely to succeed than a vague one. Keep the reply, whatever it is, because a written record of consent protects you later and a written refusal with reasons is something you can question.

A private landlord may attach conditions: a reference for the lodger, a limit on how long, sometimes a small increase in rent to reflect fuller use of the property. Those are usually worth accepting if the arrangement still leaves you better off. What you should not do is treat a landlord's silence as a yes. If you have written asking for consent and heard nothing, chase it until you have a clear answer, because "they never replied" is a weak position if it later goes wrong.

One thing consent does not do is turn your lodger into your problem to house. A lodger who shares your home is, in law, an excluded occupier, which means you can generally end the arrangement by giving reasonable notice without going to court. That makes a lodger far easier to move on than a tenant if it is not working — a genuine advantage when you are inviting a stranger into your home at a raw time, and a point worth holding on to as reassurance.

Third: what a lodger does to your benefits

This is where good intentions can quietly backfire, so it is worth being precise. The rules differ between Universal Credit and the older Housing Benefit, and they differ again between private and social tenants.

Under Universal Credit, money you receive from a lodger is generally not treated as income at all — it does not reduce your award. That is genuinely helpful: the rent the lodger pays you is yours to put towards the rent you owe, without a pound-for-pound clawback. But there is a sting for social tenants. For the purposes of the size criteria — the "bedroom tax" — a lodger does not count as needing a bedroom. So if you are a working-age social tenant with a spare room, taking in a lodger will not remove a spare-room deduction, even though the room is now occupied. We explain the mechanics, and the year's protection you may have after a bereavement, in how the bedroom tax works after a death.

Under Housing Benefit, where you are still on it rather than Universal Credit, income from a boarder or lodger is treated differently, with its own set of disregards, so the answer can change. Anyone still receiving Housing Benefit rather than Universal Credit should check their own claim before agreeing anything, rather than assuming the Universal Credit position applies.

One reassurance across the board: a lodger on a genuine commercial arrangement is not the same as an adult relative moving in. Bringing an adult son or daughter into the household can trigger a housing-cost contribution — a non-dependant deduction — whereas a lodger paying to rent a room does not work that way. If your wider award has changed since the death, it is worth reading how the Universal Credit housing element changes after a bereavement alongside this, because the two interact.

Fourth: the tax on what a lodger pays you

Money a lodger pays you is, in principle, taxable income — but a long-standing relief usually removes the problem for a single spare room. The Rent a Room scheme lets you earn up to a fixed amount each year, tax free, from letting furnished accommodation in your own home. That threshold is £7,500 a year. If you share the income with someone else — a joint owner or another resident landlord — the allowance is halved to £3,750 each.

Two points make this simpler than it looks for a bereaved tenant. First, the relief is not just for homeowners — a tenant who is allowed to take in a lodger can use it too, as long as the lodger is in your own home. Second, because your partner has died, the halving that applies when income is shared will often no longer bite, because you are now the sole resident landlord receiving it. If what your lodger pays over the year stays under the threshold, there is usually nothing to declare and no tax to pay on it. If it goes above, you have to tell HMRC and pay tax on the excess, and you can choose each year whether to use the flat allowance or be taxed on your actual profit.

The Rent a Room scheme covers a lodger sharing your home. It does not cover letting out a whole separate property, and it does not turn a subtenant with exclusive possession into a lodger. If in doubt about which side of that line an arrangement falls, that is the sort of thing HMRC's own guidance is written to answer.

Is a lodger actually the right answer?

Suppose the tenancy allows it, the landlord consents, the benefit position works and the tax is straightforward. It can still be worth pausing on whether a lodger is the right thing for you, rather than simply a thing that is possible.

There is the cost you do not see on a spreadsheet: a stranger in the home, weeks or months after a death, sharing the kitchen where two of you used to sit. Some people find it steadying to have another presence in the house. Others find it unbearable, and only discover which they are once someone has moved in. Because a lodger is easy to give notice to, the arrangement is at least reversible — but it is kinder to yourself to go in knowing it might not suit, rather than treating it as a decision you cannot undo.

There is also the question of whether a lodger is the only lever. Before you let the spare room, it is worth making sure you are claiming everything you are entitled to. An unmarried partner in particular is often owed more than they assume, and we set out what an unmarried partner can claim towards the rent after a death. And if you are under 35 and weighing whether staying put is even affordable, the cap you would face if you did claim towards a home of your own — the shared accommodation rate for renters under 35 — is part of the same sum.

Behind all of this is the reason the question arises at all: the rent was designed for two incomes and there is now one. Taking in a lodger is one way to replace part of a lost income after the event. The other, arranged before the event, is cover that pays out an income to the survivor precisely so that the spare room does not have to earn its keep and a stranger does not have to move in. Family income benefit is the form of life insurance built for exactly that — a regular payment to a household after a death rather than a single lump sum — though whether cover is offered and what it would pay always depend on underwriting and the policy terms. If you want to understand what that would look like for your household, you can get life insurance quotes through an FCA-authorised broker.

Scotland and Northern Ireland

The tax side of this is the same wherever you live in the United Kingdom, because the Rent a Room scheme is an HMRC relief that applies across the UK. The amount you can receive tax free from a lodger does not change between England, Scotland, Wales and Northern Ireland.

What changes is the tenancy question at the front of the list. Scotland and Northern Ireland have their own tenancy systems, with their own rules on whether and how a tenant may take in a lodger and on the consent a landlord can require. Scottish secure tenants and private residential tenants sit under Scottish housing law; tenancies in Northern Ireland are governed separately again. Council tax also works differently in Northern Ireland, where households pay domestic rates rather than council tax, so the single-occupant position on the bill is not identical. The safe course everywhere is the same: read your own agreement and check your own claim for your own tenancy type, rather than assuming a rule from one part of the UK carries across to another.

Frequently asked questions

Can I take in a lodger if I rent?

Only where the tenancy allows it, and most private agreements either forbid it or require the landlord's written consent. Social tenants often can, subject to telling the landlord. Doing it without permission can breach the tenancy and give a ground for possession, so ask in writing first.

How does a lodger affect my benefits?

For Universal Credit, payments from a lodger are not usually treated as income, but the lodger does not count as needing a bedroom, so a social tenant can still face a spare room deduction. Housing Benefit treats lodger income differently, so check your own claim before agreeing anything.

Do I pay tax on what a lodger pays me?

The Rent a Room scheme allows up to £7,500 a year tax free from letting furnished accommodation in your own home, halved where the income is shared. Above that you have to declare it to HMRC. The relief covers lodgers, not letting out a whole property.
