Sept 4 (Reuters) - Britain's competition regulator on Friday
launched an investigation into four of the country's biggest
housebuilders, saying they may have broken a consumer protection
law in relation to leasehold homes.

The Competition and Markets Authority (CMA) said it was
opening enforcement cases against Barratt Developments,
Persimmon Homes, Taylor Wimpey and Countryside
Properties.

The watchdog uncovered evidence of potentially unfair terms
with regard to ground rents in leasehold contracts and potential
mis-selling, it said.

"It is unacceptable for housing developers to mislead or
take advantage of homebuyers," Andrea Coscelli, CMA's chief
executive, said in a statement.

Shares of Britain's biggest housebuilder Barratt fell 2.4%
and Persimmon lost 2% while Taylor Wimpey and Countryside were
down less than 1%.

The companies all said they were co-operating or engaging
with the watchdog, with Taylor Wimpey adding that it would
provide further information requested by the CMA in the coming
weeks.

Persimmon in an emailed statement said it decided to stop
selling leasehold houses where it owns the freehold in 2017.

"We believe these are known historic issues where companies
have already taken corrective action. At this stage we see
immaterial risk to earnings or requirement for provision," said
analysts at Credit Suisse.

The CMA said the possible outcomes of its investigation
could include court action or legal commitments from companies
to change their practices.

It will also investigate certain firms that bought freehold
properties from these developers and was sending letters to a
number of other developers, encouraging them to review their
practices.

Homebuilders in the UK have been battered in recent years by
the country's decision to leave the European Union, while
coronavirus restrictions added to those woes.

However, recovery was gathering pace with mortgage lender
Nationwide saying this week house prices had leapt to hit an
all-time high in August.

Britain gave homebuyers an incentive amid the crisis by
cutting a tax for house purchases in July.
