Rightmove more than found its happy this morning, announcing record results to the City with revenue up 16% to £93.1m in the first six months of this year. Its share prices zoomed up to a new record high on the news, although subsiding subsequently.

Underlying operating profits were £70.3m, up 18% on the first half of 2014.

Operating profit margin increased to 75.5%.

Rightmove also said market share among property portals is up and that agents are spending more with it.

The portal said that average revenue per agent advertiser is up 10% on the same period last year, to an average of £740 per month.

By marked contrast Foxtons reported revenues and profits down, amid “challenging conditions”. But the high-profile London agent said that things had turned around since the election.

In its clutch of record results, Rightmove reported that customer numbers have also grown, to an all-time high of 19,590. Agency numbers are up 2%.

It reported record traffic with visits up 17% to a record 110m per month, and page views up 13% to a record 1.5bn per month.

Rightmove said that on the back of the record traffic, agents and developers received a record 25m inquiries “with data showing that Rightmove is by far the largest source of buyer, seller, tenant and landlord opportunities for them”.

More than half – 60% – of time now spent on Rightmove is from mobile devices.

Rightmove said it remained the “only place to search and research virtually the whole property market in the UK” and that it generated “over 80% of sales for agents compared to our nearest competitor and therefore home sellers are four times more likely to find a buyer on Rightmove”.

Nick McKittrick, CEO, said: “Rightmove is becoming even more popular with the British home moving public. Our share of traffic amongst the top four property websites has increased significantly as people search and research the only place with over one million properties for sale and to rent in the UK.

“We continue to innovate and invest to make Rightmove more compelling to home movers and advertisers with tools such as our Valuation range app and recently launched School Checker.

“Our aim has always been to help our agents and developers succeed by delivering great value marketing and building strong relationships to support their ambitions. This approach continues to serve us well as we have grown our customer base to reach an all-time high showing that Rightmove is the overwhelming site of choice, not only for Britain’s home movers, but also its property professionals.”

Foxtons issued a very different picture to the City, saying group revenue of £71.m for the first half of this year was down 2.3% compared with the same period a year ago.

Revenue from sales was down 10.9%, although lettings revenue was up 5.4% and mortgage broking revenues were up 21.7%.

Profits before tax were £18.1m, down from £23.1m for the same period last year.

However, Foxtons expressed optimism for the rest of this year, saying that there has been an “encouraging” performance since the general election, with a positive outlook for the rest of this year: sales stock levels are up 12.1%, and there is a sales pipeline of almost £1bn, which is 12.5% ahead of this time last year.

Nic Budden, CEO, said: “Despite challenging market conditions, Foxtons has delivered a solid result against very tough comparables, demonstrating the strength of our business model and our balanced approach to sales and lettings.

“As we predicted earlier in the year, the sales market remained constrained during the months before the General Election. With the election uncertainty now passed we have seen an increase in activity across our branch network.

“This is encouraging and we enter the second half of the year with stock levels up 12% compared to last year, a £1bn sales pipeline and our recently opened branches continuing to mature in line with expectations.

“In addition we have seen a noticeable increase in buyer applicants. Our lettings business has maintained the positive momentum seen in the first quarter of 2015.

“Our expansion has continued as planned with five new branches opened since the beginning of the year with our future sites secured out to the end of 2016. The majority of these are focused in the fastest growing areas of Outer London.

“Based on current activity levels continuing, we expect to meet full year market expectations with a stronger property sales performance in the second half of the year from higher transaction volumes.”

In early trading this morning, Rightmove shares zoomed up £2 (6%) and touched a record high of £36 before retracing to just under £35. The City also liked Foxtons’ upbeat view of the second half of this year, with its shares rising 7%, up 15p to 238p.
