Tribunal Rent Decision – HUGE Valuation Discrepancy?

This is why all landlords should be increasing rent in line annually (even if modest), rather than leaving it to accumulate. The tribunals don’t care that you as a landlord had effectively discounted the rent in previous years by not increasing. Instead they’ll interpret your delayed higher increase as unfair and limit you to something like 1.05% of the existing, outdated, low rent – as they’ve done here.

On the face of it and you have. It said how long the tenant has been in situ and how long they have been paying £640. I carry out a rent review annually and tend to increase rentals between 5-10% depending on the local area. It sounds like you have not carried out a rent review for som time as it would be difficult to justify an increase of the magnitude you have attempted. Put yourself in the tenants shoes for one moment, How would you feel if your rent was going to increase by £260 per month

I have to start by saying i have zero knowledge of this, but i suspect it is political. You tried to increase rent from £640 to £900 and regardless of whether £900 is justified, there have been several cases (involving Labour MPs if i recall) who have made similar rent increases and it does not go well. I suspect there is “pressure” (perceived or real) to hold down increases.

That said, the fact your agent said £900 is irrelevant (and begs the question why had they not put the rent up more and sooner)… What is needed is evidence of similar properties in terms of size, condition, and area and the rents those properties are obtaining

Rental figures have increased considerably in the last year, and yes may have gone up since the tenant moved in. But a nearly 50% increase on current rent will always be deemed excessive/unfair.

You don’t say how long the tenant has been living there.

I was in a similar position 4 years ago. One feckless tenant cost me £20k before I could evict him, and I sold that flat. For the remaining flat, I increased the rent by 9% on each of the last 3 review dates. I finally hit the market rate and the tenant complained, so I suggested she go to the Tribunal. She left, which allowed me to increase the rent again to just above the market rate. I got a well referenced tenant within weeks, who is paying £500pm less than where she lived before.

While an increase of this magnitude can be justified as unfair when we are subject to the legislation in the RRB I expect that the use of tribunals will become commonplace.
I think they will be used as a mechanism for keeping rents low.
This is what happened pre 1988 rent act.
The tribunals will pay little attention to expenses incurred by landlords.

If you read a few examples of market rent determinations it should give you some guidance about the level of detail commonly provided by the parties.

It’s not a question of fairness to the individual tenant.

“In accordance with the terms of section 14 of the Act, the Tribunal is
required to determine the rent at which it considers the subject property might
reasonably be expected to let on the open market, by a willing landlord,
under an assured tenancy, on the same terms as the tenancy.”

Very helpful.

Case reference HAV/23UB/MNR/2025/0677

The landlord asked for a £300pm increase because the rent to that tenant had not been increased for 4 years. The Tribunal agreed the increase at £275pm.

Such posts beg the questions to the level of advice your agent is giving you. If my clients fee the need to seek a second opinion on a public forum i would be concerned.

If the agent believes that the MR is £900 then they should have provided you, and the tenant, the evidence. That way you would know if the Tribunal had acted correctly.

Your agent should then be telling you how to proceed. Is the case good? What are the implications? What are the costs? Unless you get this advice you are guessing.

Maybe the condition of the house isn’t as good as you (or your agent) think it is.
