保守党影子财政大臣安德鲁·格里菲斯表示，如果他的政党重新执政，将通过削减法规，将英格兰和威尔士建造新住宅的成本降低5万英镑。
Conservative shadow chancellor Andrew Griffith has said his party, if it was returned to power, would take £50,000 off the cost of building a new home in England and Wales by cutting back on regulations.
格里菲斯所声称的5万英镑，反映了房屋建筑行业对新法规和新税收成本的估算。
The £50,000 figure claimed by Griffith reflects estimates by the housebuilding industry of the costs of new regulations and taxes.
然而，建筑和住房专家警告称，部分节省下来的资金最终可能导致政府在教育、道路和保障性住房方面的支出增加。
However, construction and housing experts warn that some of the savings could ultimately lead to higher government spending on schools, roads, and affordable housing.
一些分析人士还警告说，保守党计划废除环境法规，未来可能会推高家庭能源账单。保守党认为，多项法规正在增加新建私人住宅的建造和交付成本。这些法规包括：社区基础设施税——英格兰和威尔士某些新开发项目需缴纳的一项费用，地方议会可用这笔资金资助道路、学校和游乐区等本地基础设施；未来住宅标准——要求英格兰新建住宅达到更高的能源效率标准，并使用热泵等低碳供暖方式，而非燃气锅炉；第106条——该条款可能要求开发商在英格兰的新开发项目中提供一定比例的社会保障性或经济适用房。
And some analysts also warn the Conservative plans to scrap environmental regulations could potentially push up household energy bills in future. The Conservatives argue a number of regulations are adding to the cost of constructing and delivering new private homes. These include: The Community Infrastructure Levy - a charge on certain new developments in England and Wales which councils can use to fund local infrastructure such as roads, schools and play areas The Future Homes Standard which requires new-build homes in England to meet higher energy-efficiency standards and use low-carbon heating such as heat pumps rather than gas boilers Section 106 which can require developers to provide a proportion of social or affordable housing in England as part of a new development.
保守党表示，他们将废除或改革这些及其他法规，并称：“总而言之，我们将把新建住宅的交付成本，以及由此带来的购房成本，最多降低5万英镑。”BBC Verify已向保守党要求提供这一数字的详细分解。
The Tories say they will scrap or reform these and other regulations, saying: "All in all, we will cut the cost of delivering and therefore buying a new home by up to £50,000." BBC Verify has asked the Conservatives for a full breakdown of their figure.
英国房屋建筑商联合会（HBF）估计，自2020年以来，新法规、税收和通货膨胀已将英格兰和威尔士建造一套新住宅的成本增加了7.6万英镑。该联合会表示，这一金额约占一套平均新住宅价值的20%。在这一总额中，其估算如下：985英镑来自第106条规定，10,200英镑来自“未来住宅标准”，另有12,700英镑用于环境保护措施，例如“养分中性”和“生物多样性净增益”。
若不计材料成本和人工费上涨的37,000英镑，英国住房建筑联合会（HBF）估计，相关法规与税收已使新建住宅的成本增加了约42,000英镑。
The Home Builders Federation (HBF) has estimated that new regulations, taxes and inflation - since 2020 - have increased the cost of building an individual new home in England and Wales by £76,000. It says this represents around 20% of the value of an average new home. Of this total, it estimates: £985 comes from Section 106 £10,200 comes from the Future Homes Standard £12,700 in environmental protection measures such as "nutrient neutrality" and "biodiversity net gain" Excluding a £37,000 increase in the costs of material and labour, the HBF estimates that regulations and taxes have added around £42,000 to the cost of building a new home.
保守党的估算略高于HBF的数据。HBF的估算还包含了近8,000英镑，以反映建筑法规的变化。保守党尚未表示会通过废除所有这些法规来节省开支。
The Conservatives' estimate is slightly higher than the HBF's figure. The HBF also includes nearly £8,000 to reflect changes in building regulations. The Conservatives have not said they would find savings by scrapping all of those.
该党的计划还假设，他们强调的节省成本将转嫁给购房者，而不是提高房屋建筑商的利润。
The party's plan also assumes the savings they have highlighted would be passed on to buyers rather than raising house builders' profits.
贸易组织“建筑产品协会”（CPA）的诺布尔·弗朗西斯告诉BBC Verify，近年来通过法规与税收向建筑商征收的新成本——包括企业为应对监管体系所花费的时间——已成为住宅建筑速度的严重制约因素。
Noble Francis of trade body the Construction Products Association (CPA) told BBC Verify that new costs imposed on builders through regulations and taxes in recent years - including the time firms spend navigating the regulatory system - are a serious constraint on residential construction rates.
在实现本届议会期间在英格兰净增150万套住房的目标方面，工党政府已严重偏离轨道——这一目标要求每年新建约30万套住房。
The Labour government is well off track in terms of meeting its target of building 1.5 million net additional dwellings in England over the course of this parliament - which requires an annual building rate of around 300,000 homes per year.
根据官方估算，截至6月的这一年，实际仅新建了约20.3万套住房。
In the year to June only around 203,000 were built, according to official estimates.
不过，弗朗西斯也表示：“任何非执政党都很容易声称自己会消除繁文缛节、削减成本，但保守党和工党在过去五年中均曾执政，并且都增加了房屋建筑的成本。”例如，“未来住宅标准”最初是在2019年，时任保守党首相鲍里斯·约翰逊执政期间提出的。
However, Francis also said: "It's easy for any party not in government to just claim they will get rid of red tape and cut costs but both the Conservatives and Labour have been in power in the last five years and have added extra costs to house building." The Future Homes Standard, for instance, was first proposed in 2019 when Conservative Prime Minister Boris Johnson was in power.
其他分析人士指出，该计划带来的初期建筑成本节省，未来可能会导致政府支出增加。
Other analysts point out that the upfront construction cost savings from the plan could potentially lead to higher government spending in the future.
住房专家安娜·克拉克表示：“将房屋建造成本降低5万英镑，对于建造急需的新住房将大有裨益。
Housing expert Anna Clarke said: "Cutting the costs of house building by £50,000 would be really helpful in getting much-needed new homes built.
“但如果不能让开发商为新学校和基础设施买单，就需要通过其他方式来支付这些费用。”一些分析人士则认为，更新后的建筑环保标准——例如要求新建住宅使用热泵而非燃气锅炉——预计从长远来看，能通过降低家庭能源账单为住户节省开支。
"But if you don't get developers to pay for new schools and infrastructure you need to pay for them some other way." And some analysts argue that updated environmental building standards, such as requiring heat pumps rather than gas boilers in new homes, are forecast to save households money in the long-term by reducing their domestic energy bills.
清洁能源倡导组织“监管援助项目”的理查德·洛维斯博士告诉BBC Verify：“如果不仔细考虑能源账单的影响，家庭可能会在未来几十年里面临极高的账单。
Dr Richard Lowes of clean energy advocates the Regulatory Assistance Project told BBC Verify: "If the energy bill implications are not carefully considered, households may be lumbered with very high bills for decades.
“通常，将热泵与太阳能和电池结合使用，可以实现最低的运营成本。”
"The lowest running costs can typically be achieved with heat pumps paired with solar and batteries."
