A supply last week stated that if everybody eligible to do so claimed income, the liabilities could be in the region of £30m. 

The Telegraph understands that the oversight – an mistake in fundamental tenancy law – dates 2012 and tenants have a six-12 months limitation period in which to make a assert versus either an agent or their landlord.

Purplebricks stated: “The firm not long ago turned knowledgeable of a procedure difficulty in how it has been speaking with tenants on behalf of its landlords in relation to deposit registrations. 

“Further enquiries into this issue are at this time staying executed and the communications procedure is now staying corrected.”

Purplebricks, which was started in 2012 and floated on Purpose in 2015, was seriously decline-producing right until April this 12 months, when it described its initially whole-12 months pre-tax profit of £3.6m, on sales of £90.9m.

It had £58m of cash on the equilibrium sheet in Oct, which usually means it must be in a position to soak up any statements “comfortably”, in accordance to analysts at Peel Hunt, who have place their score on the shares below critique.

The firm has had a hard time in the past few months as it offers with a variety of separate problems.

Purplebricks has confronted statements it unsuccessful to sign-up tenant deposits with a governing administration-authorized security plan, blaming an IT glitch for the mistake.

The firm is also disputing accusations from estate brokers who think they are entitled to vacation fork out and pensions contributions from Purplebricks, inspite of staying classed as self-utilized by the firm. Previous month it issued a profit warning immediately after business dropped.

Its share value has tumbled by 95pc more than the past 4 a long time and the stock is now value just a quarter of its float value of 100p.

Deloitte declined to comment.
