Around month ten of a London tenancy, an email arrives: your landlord would love you to stay — at £20 a week more. First-time renters often treat the number as weather: unpleasant, unarguable. It's neither. Renewals are the one moment in the rental year when you hold real leverage. Here's how the decision actually works.
First, Know What Happens If You Do Nothing
On most 12-month ASTs, if neither side acts, the tenancy rolls into a periodic (month-to-month-style rolling) arrangement on the old terms. That's not a trap — it's often fine — but it swaps security both ways: you can leave with short notice, and the landlord can serve notice or raise rent through the formal process. If you want certainty for another year, a renewed fixed term is the tool; if your plans are fuzzy, periodic can be the smarter interim. (Contract mechanics here.)
Your Leverage, Itemised
A sitting tenant who pays on time is worth real money to a landlord: no void weeks, no relisting fees, no referencing costs, no repaint between tenants — typically £1,000–£2,500 of avoided cost. That's your negotiating position. A proposed increase is an opening number, not a verdict, and the counters that work are boringly factual:
1. Comparable listings. Three current ads for similar rooms in your postcode at or below your current rent — screenshots, not vibes. 2. Your record. Twelve months of on-time payment, zero complaints, documented. 3. The void maths. "A £15/week increase earns you £780 a year; one empty month costs you more than that" — said politely, in writing. 4. A trade. Accepting a small increase in exchange for a repair, a repaint, or a longer fixed term is a legitimate deal.
When Moving Beats Staying
Run the honest comparison: the all-in cost of staying (new rent + the bills you now know are real — especially winter energy) versus the all-in cost of a move (new deposit floated before the old one returns, time, a van, the admin week). Moving wins when the gap exceeds roughly £25–30/week, when the flat has unresolved problems a renewal would reward, or when your commute changed and the postcode no longer earns its rent. Moving loses when it's purely about a £10 increase — the friction eats the saving.
The Deposit Hand-Off Trap
If you do move: your old deposit returns after you leave, but the new one is due before you arrive — so you'll float both at once. Budget for it, photograph the old room at checkout exactly as you did at move-in, and chase the protected scheme, not the landlord, if the return drags. The deposit rules.
How Renewals Work at Nook
Managed housing simplifies this annual ritual: renewal terms arrive in writing well before the end date, the price is the price for everyone (no haggling asymmetry between confident and shy tenants), and bills stay inside the one weekly number — so the renewal comparison is one figure against the market's rent-plus-bills guesswork. And if you want to change rooms rather than providers at renewal, that's an internal move, not a double-deposit float. The rent-a-room guide covers the rest.
Renewal letter in hand? Counter it with comparables before the deadline — and if the numbers say move, see what an all-in room costs now.
