Construction software for Wales, and the rules that are Wales’s

Since 1 December 2022 a landlord in Wales lets under an occupation contract rather than a tenancy, and the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022 set the conditions the dwelling has to meet: a smoke alarm on each storey, connected to the electrical supply and linked to every other one, a carbon monoxide alarm in each room with a gas, oil or solid fuel appliance, and an electrical installation condition report no more than five years old.

• The electrical report is given to the contract-holder within 7 days of the occupation date, and a report from an inspection during the contract within 7 days of it.
• The Schedule to the regulations lists 29 matters and circumstances a landlord has to have regard to in deciding whether a dwelling is fit, the hazards of the Housing Health and Safety Rating System among them.
• The Property Compliance register renews EICR at 60 months and smoke and CO alarms at 12 months per property, with every interval editable, so a Welsh stock records the Welsh authority for each.
• Landlord gas safety is the same twelve months under regulation 36 of the Gas Safety (Installation and Use) Regulations 1998, which extend to Wales.

NoteThe register’s stated authority for the EICR interval is the England regulation. A Welsh landlord edits the citation as well as the number.

No. The Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 extend to England and Wales as an instrument and apply to lessors of social homes in England. A Welsh social landlord is not on the 10, 3 and 5 working-day clocks.

• The Welsh fitness regulations are the standard a Welsh landlord answers to, and the Housing Health and Safety Rating System hazards are among the matters they list.
• Estimark’s Awaab’s Law cases are written to the English regulations. A Welsh landlord runs damp and mould repairs on the priority SLA it sets in the repairs register, not on a computed statutory clock.

A Welsh regime for the occupation of multi-occupied residential buildings, laid before the Senedd as a Bill on 7 July 2025. It sorts buildings into three categories: Category 1 at least 18 metres or at least 7 storeys, Category 2 at least 11 metres or at least 5 storeys but below Category 1, and Category 3 below 11 metres and fewer than 5 storeys.

• The English higher-risk building regime under the Building (Higher-Risk Buildings Procedures) (England) Regulations 2023 applies in England only.
• When the Welsh duties commence is set by Welsh Ministers, and a contractor on a Welsh block should read the current commencement position rather than assume the English dates.
• Estimark holds nothing for either regime. Its Building Control Pack is for an extension, a loft conversion, a change of use or a new build.

The Scheme for Construction Contracts (England and Wales) Regulations 1998 govern the fallback payment periods in Wales as in England, and the bank holiday list is the same, so the payment notice dates and the working-day arithmetic Estimark computes are right for Wales.

• CIS, the VAT reverse charge, CDM 2015 and RIDDOR 2013 apply in Wales as in England.
• The Building Regulations 2010 extend to England and Wales, and the Building Control Pack drafts for the full plans, building notice and regularisation routes.
• The planning bolt-on reads the published English planning datasets and does not cover Wales. The estimating benchmark carries a Wales labour rate index.
