A tenancy is an agreement about a home, but it is proved by paper. When a question surfaces a year in, memory rarely settles it. What settles it is the document written at the time, by someone who was standing in the room.
Private renting in England has been through a long stretch of change, with new provisions arriving in stages rather than in one go. Whatever the position on the day you read this, a handful of habits hold. Keep the documents. Date them. Describe what is visible rather than what you think caused it. Check the current rules at source instead of trusting a newsletter you saved last spring.
What follows is practice rather than law, and it is not legal advice. GOV.UK carries the government's current guidance on private renting, legislation.gov.uk carries the statutory text, and anything that turns on one property or one tenancy deserves a solicitor's eye.
Start with the terms
An agreed written statement of the terms, given at the start and signed or acknowledged, is the spine of the file. It should say who the parties are, what is let, what is included, how rent is paid, what the tenant is responsible for and what the landlord is responsible for. Where a term is unusual, spell it out in ordinary words rather than relying on a clause number.
A statement nobody can follow is not much use five years later. Write it so a stranger could pick it up and understand it.
The record of condition at the start
The inventory made at the beginning of a tenancy is the foundation for everything that follows. It should work room by room, in the same order every time, so that later comparisons line up without effort. For each room, describe surfaces, fixtures, fittings, appliances and the state of decoration and cleanliness. Note what is there, what is missing and what is already worn.
Take meter readings on the day. Photograph anything a description struggles to carry: a scuff on a skirting board, a chip on a worktop, a patch of discolouration on a ceiling. Date the photographs, and let the written record say what each one shows, because an image with no caption invites argument.
Then have it acknowledged. A tenant who has read the record, commented on it and signed it is in a very different position from one who never saw it.
Describe, do not diagnose
An inventory records condition. It does not establish cause, and the two get muddled more often than anything else in this work.
Damp and mould are the clearest example. Write down where the mark is, how far it spreads, what sits next to it and what the surface feels like. Record any readings taken, with the instrument used, the reading and the time. That is the observation. What produced the moisture is a separate question, and it is not answered by describing how a household lives. Cooking, washing, bathing and drying clothes put moisture into the air in every home, and a record that stops at that observation has not found a cause. The condition of the building, the ventilation and any defect are matters for the landlord to investigate.
The same discipline applies to wear. A worn carpet is a fact. Whether the wear is fair is a judgement somebody else will make, and it is not the job of the person holding the clipboard. Describe the wear, its position and its extent, then leave it there.
Pets and permissions
Where a tenant asks to keep an animal, put the request in writing and put the answer in writing too, with a date on both. Note any conditions attached: which animal, how many, what insurance if any is in place, and what the tenancy says about it.
At each visit, describe pet related condition as found. Marks to a door, wear to a garden edge, a chewed corner on a fitting, hair in a carpet. Visible facts, plainly set out, are what a later conversation needs.
When something changes during the tenancy
Tenancies are not static. Boilers are replaced after a failure. A carpet is renewed. A shower room is refitted, or a shelf is put up and later taken down. None of it appears in the record unless somebody writes it down, and the person most likely to have been there is whoever carried out the visit.
A visit during the tenancy is also the sensible moment to check that the original record still describes the property, and to note where it no longer does. Date the addition, say who made it, and keep it with the original rather than in a separate file.
The comparison at the end
The final inspection is a comparison, not a fresh start. Work through the same rooms in the same order, against the same descriptions, and say plainly where the property matches the original record and where it does not. Photograph from similar positions so the two sets of images can be read side by side.
A record of this kind does not decide what happens to a deposit and it does not settle who pays for what. It shows condition at two points in time, which is a different and more modest thing, and it is the thing a landlord, a tenant and anyone else involved actually needs.
Keep the paper trail
The condition record is only part of the file. Keep the tenancy agreement and any statement of terms, the deposit paperwork, correspondence about repairs, notices about rent with the date each was given, and the tenant's reply. Where a procedure applies to a rent increase or to what may be charged, the paperwork is the evidence that it was followed, so check the current guidance before you act rather than after.
Store it where it can be found. A document that exists only in somebody's inbox is not a record; it is a hope.
Where to check
GOV.UK is the place to begin for the current position on private renting in England. legislation.gov.uk holds the statutory text, and it is the only reliable source for a contentious point. Your local authority can explain its own enforcement role. For a particular property or a particular tenancy, take legal advice.
What has not changed is the value of a clear, dated record made by somebody who was there. Rules move. Recollection fades, and it was never even handed. The description written down at the time, room by room, in plain words and honest photographs, outlasts both.
