(Sharecast News) - FTSE 250 housebuilder Bellway reported a rise in full-year profit and revenue on Tuesday as completions breached the 10,000 mark for the first time amid strong demand.In an update for the year to the end of July, the company said pre-tax profit rose 14.3% to £641.1m on revenue of £2.96bn, up 15.6% on the previous year. Bellway, which lifted its dividend by 17.2% to 143p a share, breached the 10,000 homes barrier for the first time as it completed the sale of 10,307 homes versus 9,644 the year before.The company said demand for new housing has been strong across all of its geographies, contributing to an all-time high sales rate of 200 reservations per week, up 7% on 2017. The performance was stronger in the second half of the year, following the usual seasonal trend with the onset of the spring selling season.Meanwhile, the pricing environment was generally positive, with sites located in affordable areas, where demand is strong, still able to achieve low, single digit price rises. Demand was less pronounced at the higher end of the market, however, where affordability was a greater constraint for some purchasers and where pricing gains were more difficult to achieve.Bellway said Help-to-Buy is still an important selling tool, accounting for 39% of completions in 2018 versus 35% last year."The ongoing availability of Help-to-Buy underpins the sector's ability to continue growing output. It provides affordable access to mortgage finance for many, particularly those hoping to make their first move on the housing ladder, with approximately 67% of Bellway customers using Help-to-Buy being first time buyers."Bellway said it had a strong order book of £1.47bn at 30 September compared to £1.36bn on 1 October 2017."Whilst there is a risk to consumer confidence posed by the forthcoming exit from the EU, assuming that market conditions remain robust, Bellway has a solid platform from which to further increase output in the year ahead," it said.Bellway also said on Tuesday that there remains upward pressure on build costs throughout the industry as housebuilders continue to increase output."A shortage of skilled labour remains the greatest constraint to growth, but there is also a shortage of key materials, such as structural timber, plastics, bricks and blocks, with these exacerbated due to capacity issues in the broader building materials sector. Looking ahead, in order to mitigate some of these cost pressures, offset some of the reducing benefit of house price inflation and therefore help to protect the margin in the years ahead, the group is introducing a number of positive cost control initiatives."These initiatives include the development of the 'The Artisan Collection', a new rationalised range of 24 standard group house types, which its divisions have been plotting since June 2018. The houses are designed to appeal to its customers' aspirations while helping to achieve cost savings through greater standardisation, thereby helping to protect the margin in the future.
