One Week Out: UK Rental Market Update (23 April 2026)

The Renters' Rights Act takes effect on 1 May, buy-to-let mortgage costs are surging, and the ONS confirms rental growth is cooling to its slowest pace in four years.

If your compliance team hasn't mapped out the Information Sheet distribution for every tenancy in your portfolio, this is the week to get it done. The 1 May commencement date for the Renters' Rights Act is now seven days away, and the operational changes coming are not incremental. Meanwhile, the latest ONS data shows annual rent growth cooling to 3.4%, the slowest since 2022, a signal that pricing accuracy now matters more than it did six months ago. Across the LightWork AI platform, around four in five new lettings enquiries are being auto-qualified with an average response time of under 20 seconds, a tempo that reflects how competitive the lettings market has become as supply begins to loosen.

The Top Headlines

1. Information Sheet must reach every tenant by 31 May or face fines of up to £7,000

From 1 May 2026, all assured tenancies in England convert to periodic arrangements under the Renters' Rights Act. Landlords and their managing agents must provide the government-published Information Sheet to every tenant with a written tenancy agreement by 31 May 2026. The sheet must be provided as an unaltered PDF, either digitally or in print. Failure to comply carries a financial penalty of up to £7,000 per tenancy. For agents managing portfolios of 200+ units, that is a bulk distribution exercise that needs to start this week if it hasn't already. Check whether your CRM or property management software supports batch document sends before you default to manual emails. If you're a landlord managing without an agent, the obligation sits with you directly. Source

New information sheet for landlords under the RRA

The Renters’ Rights Act 2025 requires landlords to serve a new government information sheet on every existing tenant by 31 May 2026. Fines for non-compliance reach £7,000 per breach. This guide covers what’s required, who it applies to, and how to stay compliant.

2. ONS confirms rent growth slowing to 3.4%, lowest annual rise since 2022

Average UK monthly private rents rose 3.4% year-on-year to £1,377 in the 12 months to March 2026, down from 3.6% the month before. The regional picture is uneven: the North East leads at 6.5% annual growth, while London has slowed to just 1.7%. Average rent in England now sits at £1,434, with London at £2,280 and the North East at £772. Wales (4.8% to £830) is outpacing both England and Scotland (2.1% to £1,022). For agents pricing new lets, this data is a reminder that blanket annual increases are no longer defensible in every market. Regional benchmarking is now essential to avoid overpricing and extending void periods. Source

3. 220,000 PRS households expected to exit the sector by year-end

An estimated 220,000 private rented households will leave the market by the end of 2026, roughly 5% of England's rental stock. Single-property landlords are the most likely to sell, with exit decisions driven by the Renters' Rights Act, Making Tax Digital obligations, and pressure on yields. For agents, this creates a dual challenge: retaining the landlords you have while absorbing the stock that transfers between agencies as portfolios change hands. If your client list is weighted toward one-to-two property landlords, expect exit conversations to accelerate over the next quarter. Retention strategies and proactive compliance support are the differentiators that keep quality landlords on your books. Source

4. Buy-to-let mortgage rates post biggest monthly jump since the mini-Budget

The average two-year fixed buy-to-let mortgage rate rose from 4.66% to 5.44% between 1 March and 1 April, while five-year fixes climbed from 5.05% to 5.75%. That is the sharpest single-month increase since September 2022. The Bank of England held the base rate at 3.75% in March, but swap rate volatility driven by global uncertainty is pushing fixed-rate pricing higher. For landlords remortgaging this quarter, the numbers may not stack up the way they did three months ago. Agents fielding calls from nervous landlords should be ready with updated yield calculations that account for the new cost of finance. Source

5. Local Housing Allowance frozen again, widening the gap for benefit-claiming tenants

LHA rates for 2026-27 remain at 2024 levels despite average UK rents rising 10.5% since those rates were set. Only 2.7% of homes in Great Britain are now affordable for tenants relying on housing benefit. In Scotland, 87 of 90 LHA rates fall below the 30th percentile of local market rents. For agents managing portfolios that include benefit-claiming tenants, the practical implication is growing arrears risk and a shrinking pool of affordable stock to offer. If you're a landlord considering whether to accept LHA tenants, the gap between allowance and market rent is now the widest it has been in a decade. Source

Why this matters

Seven days out from the biggest structural change to English tenancy law in a generation, and the market is moving on multiple fronts simultaneously. Rent growth is cooling, landlord exits are accelerating, mortgage costs are climbing, and the benefit system is falling further behind market reality. The agents who will come through this period strongest are those with operational capacity to handle compliance at portfolio scale, respond to enquiries at speed, and give landlords real-time visibility on performance. From the data we see on the LightWork AI platform, close to half of all tenant and prospect conversations are happening outside office hours, which tells you something about when the market is actually moving versus when most teams are staffed to respond.
