Transaction levels are set to be “significantly” below those of last year, and next year’s sales volumes will be lower still.

The forecast comes from Countrywide, which this morning issued a gloomy trading update covering the third quarter of this year. Shares plunged in initial trading this morning to below 165p, down from 193p, but recovered to just above 180p by 9am.

The UK’s largest agent said that its EBITDA (profits after costs and depreciation) for this year will be “around the lower end of market expectations”.

It said that at the end of September the pipeline across its “retail” business was down 16%, and in its London business down 26% compared with a year earlier – pointing to a bleak fourth quarter in terms of revenue for the business.

Countrywide said the fall in transactions – likely to end at 6% down this year – was due to a combination of the EU referendum and changes in Stamp Duty.

Its revenue fell in the third quarter to £188.5m, down from £197.1m for the same period last year.

However, revenue for the first nine months of the year totalled £558.7m, up from £535.7m for the same period last year.

The trading update makes only a fleeting and oblique reference to branch closures, saying that it aims to have “fewer, better brands”.

However, Countrywide said this morning that it is “delighted” with its online pilot and that branches in the trial had recorded consistent out-performance when measured against a control group.

CEO Alison Platt said: “We have made good progress this year despite tough market conditions since the EU referendum, particularly pleasing is our growth in market share in both sales and lettings based on available market data up to July.

“In addition, these results in our lettings, mortgage and professional service businesses underline the importance of the breadth of the group and the focus we have placed on keeping the customers we win and continuing to serve them.

“In light of the Chancellor’s announcement yesterday regarding letting agents’ fees, we look forward to working with the Government through this consultation process.

“The results of our digital sales pilot and the roll out of Fixflow in Lettings signal strong steps towards building our multi-channel network across the UK.

“Our work to ensure we have fewer, better brands and branches continues at pace.”

Separately, Belvoir released a statement to the stock market this morning, saying that gross profit will be impacted by yesterday’s ban on letting agent fees.

It says the impact is anticipated to be under 8%.

It said: “At this stage, Belvoir cannot fully predict the likely financial impact on the results for the year ended December 2017 and beyond.  Based on the Group’s experience following a similar decision in Scotland in 2012, however, the Board anticipates that mitigating action should be possible over time and indeed it should be noted that no franchisees were lost in Scotland as a consequence.

“The Board believes that less than 10% of the income derived by franchisees is from fees to tenants and, due to the broader revenue streams to the Group, the impact on total Group gross profit is anticipated to be less than 8%.  The impact may well be far greater for many of the large number of independent letting agents. 

“The Board will review and assess the likely impact of these proposed measures and will provide further updates in due course.”

However, Purplebricks – also reporting to the stock market – said it does not expect the ban to have any “meaningful” impact on its business.

It told the City: “Tenant fees charged by Purplebricks are modest and highly competitive, when benchmarked against peers. Up-front fees for tenants are currently £175 (inc VAT) outside London and £209 (inc VAT) in London.

“Purplebricks does not charge renewal fees. Purplebricks anticipates that it can adapt the model swiftly and at minimal cost, and when combined with its low fixed overhead model and pricing structure, should prove even more attractive for landlords seeking excellent service and better value.”
