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

Since 27 October 2025 a registered provider of social housing in England must investigate a significant damp and mould hazard within 10 working days of becoming aware of it, give the tenant a written summary within 3 working days of the investigation ending, and complete the relevant safety work within 5 working days of it ending. An emergency hazard must be investigated and made safe within 24 hours.

• The duties come from the Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025, made under section 10A of the Landlord and Tenant Act 1985, and they are an implied term of the tenancy enforceable in the county court.
• A working day excludes Saturdays, Sundays, Christmas Day, Good Friday and bank holidays in England and Wales. The 24-hour emergency clock is wall-clock time and runs through all of them.
• From 30 November 2026, Phase 2 extends the same clocks to excess cold and heat, falls, electrical hazards, fire and explosions, structural collapse and domestic hygiene.
• An Awaab’s Law case in Estimark holds the date the landlord became aware and its source, computes every deadline in working days, and records the date a deadline passed. There is no compliance score.

NoteThe regime applies to social homes in England. Scotland’s equivalent starts on 6 October 2026 under its own regulations and reaches private landlords too, and neither instrument reaches Wales or Northern Ireland.

Since 1 October 2023 every building project in England has dutyholders under Part 2A of the Building Regulations 2010: a client, designers, contractors, and where more than one contractor is or will be working on the project, a principal designer and a principal contractor appointed by the client in writing before the construction phase begins.

• The names match CDM 2015 and the appointments do not. A firm appointed principal contractor under CDM has not been appointed under the Building Regulations by that act, and the client has to do both.
• Part 2A also sets competence requirements for designers, contractors and the two principals.
• Estimark’s CDM project record names the principal designer and principal contractor, holds the pre-construction information, the construction phase plan and the health and safety file, and an F10 record holds the particulars for a notifiable project.

NoteEstimark holds the CDM appointments. It has no separate record for the Building Regulations Part 2A appointment, so where both apply the second is a document you keep.

A higher-risk building is one in England that is at least 18 metres high or has at least 7 storeys and contains at least 2 residential units. Since 1 October 2023 its design and construction go through the Building Safety Regulator rather than local authority building control or a private approver, under the Building (Higher-Risk Buildings Procedures) (England) Regulations 2023.

• For the design and construction phase the description also takes in care homes and hospitals that meet the height or storey condition.
• The regulator’s building control approval is needed before the work starts, and its completion certificate before the building is occupied.
• The Building Control Pack bolt-on drafts the documents for an extension, a loft conversion, a change of use or a new build on the full plans, building notice or regularisation route, at £49 a month +VAT. It is for that work and no other.

NoteEstimark prepares nothing for the Building Safety Regulator and holds no golden thread. A contractor on a higher-risk building keeps that record elsewhere.

In England a landlord of a private rented home must have the installation inspected at intervals of no more than five years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, with a penalty of up to £30,000 for a breach. Scotland reaches five years through section 19A of the Housing (Scotland) Act 2006, in force since 1 December 2015, and Wales through the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022.

• The Property Compliance register renews EICR at 60 months per property and cites the England regulation for the interval. The interval is editable per property, so a Scottish or Welsh stock sets its own and records why.
• Landlord gas safety is the same in England, Scotland and Wales, at twelve months under regulation 36 of the Gas Safety (Installation and Use) Regulations 1998. Northern Ireland has its own 2004 regulations with the same regulation number.

CIS, with its 6th-to-5th tax months and the CIS300 due on the 19th, and the VAT domestic reverse charge under section 55A are HMRC’s and apply across the UK. CDM 2015 and RIDDOR 2013 apply across Great Britain, with Northern Ireland running its own CDM regulations of 2016 to the same notification thresholds.

• The payment notice deadlines Estimark computes follow the Scheme for Construction Contracts (England and Wales) Regulations 1998 defaults where the contract is silent: a payment notice within 5 days of the due date, a final date 17 days after it, and a pay less notice 7 days before the final date.
• The planning bolt-on reads the published English planning datasets and Environment Agency flood records, and does not cover the other three nations.
• Labour rates in the estimating benchmark are held by region, with London, the English regions, Wales, Scotland and Northern Ireland each carrying their own index.
