Rent Increase Calculator UK
This rent increase calculator takes your current rent and a proposed rise and shows your new monthly rent plus exactly how much extra you’ll pay each month and year. Use the rent increase calculator below before you agree to a new figure — a few percent adds up fast.
How to respond to a proposed rent increase
Start by working out the real cost. Put your current rent and the proposed percentage into the rent increase calculator above so you know exactly how much more you’d pay each month and over a year — a “small” 6% rise on £1,200 is another £864 a year. Then check the increase against similar local listings; if comparable homes are letting for less, you have a reasonable basis to negotiate.
In England, a landlord on a periodic tenancy normally proposes a rise once a year using a Section 13 notice, and it must be fair and in line with the local market. If you think it’s above market rate you can challenge it at the First-tier Tribunal, which can set it lower. Reply in writing, keep a record, and use the figures from the rent increase calculator to make a calm, evidenced counter-offer — landlords often prefer a reliable tenant to a costly void.
Rent increase rules differ across the UK
The maths is the same everywhere — but your rights depend on where you live. England, Wales and Scotland each have their own rules on how a landlord must propose a rise, how much notice you get, and how you can challenge it.
England
For a periodic tenancy a landlord usually proposes a rise once a year with a Section 13 notice (at least one month's notice). There's no cap, but you can challenge an above-market figure at the First-tier Tribunal, which can set it lower.
GOV.UK ↗Wales
Under the Renting Homes (Wales) Act, landlords must give at least two months' written notice of a rent increase (an RHW notice) and can normally raise rent only once a year. There's no fixed cap; unfair rises can be challenged.
GOV.WALES ↗Scotland
On a Private Residential Tenancy rent can rise at most once every 12 months with three months' notice. You can refer the increase to Rent Service Scotland for adjudication. Scotland has also used temporary rent caps at times.
GOV.SCOT ↗Northern Ireland has separate rules again — check nidirect for private tenancy rights.
