Some buyers have also complained about the quality of its homes, citing problems ranging from a lack of sealant in bathrooms to the heads of nails poking through walls, issues that have been highlighted in media reports.
The group said its pre-tax profit would fall around 25 percent to roughly 115 million pounds after one-off charges linked to restructuring, extra work it is undertaking to improve its homes and merger talks.
The number of homes it built in 2017 fell by 8 percent to 3,645 units as it focuses on improving quality.
Chief Executive Greg Fitzgerald, appointed only last April, told Reuters 2018 full-year profit should meet consensus expectations of around 155 million pounds.
"Our forward order position is strong, and with robust industry fundamentals, we expect the Group to deliver a significant improvement in profitability in 2018," he said.
Bovis shares traded 3 percent higher at 0820 GMT.
Barratt, Britain's biggest housebuilder, on Thursday reported a flat sales rate in the last six months of 2017, adding that prices rose and it expects to build even more homes this year.
Bovis has also initiated a number of changes to address shortcomings in quality.
"There's no one single golden bullet: One, we've improved most importantly, and have still got some work to do, the quality of our site managers," Fitzgerald said.
"We've also got five new production directors...we've got a number of new contract managers and that in itself brings in a number of new sub-contractors that we can bring in within our supply chain."
Bovis, whose previous chief executive quit last year prompting rivals Galliford Try and Redrow to make unsuccessful takeover bids, announced a plan in September to rein in growth plans, reduce its land bank and cut staff.
