Property & Construction
42 plain-English property & constructionterms explained — part of the Yolist UK trade & business glossary.
- Approved Inspector
An Approved Inspector is a private-sector alternative to Local Authority Building Control for Building Regulations sign-off in England and Wales. Approved Inspectors are registered with the Construction Industry Council Approved Inspectors Register (CICAIR) and must carry mandatory PI insurance. They issue an Initial Notice at project start and a Final Certificate on completion. Following the Building Safety Act 2022 they have been reclassified as Registered Building Control Approvers.
- Article 4 Direction
An Article 4 Direction is a formal notice made by a local planning authority (LPA) to withdraw specified Permitted Development Rights from a defined area, requiring property owners to make a full planning application for works that would otherwise not need one. They are commonly used in Conservation Areas to protect character — for example requiring permission to replace windows or render a facade — and by councils seeking to control the proliferation of Houses in Multiple Occupation by requiring planning permission for conversions. An Article 4 Direction must be confirmed by the Secretary of State or the LPA following a defined consultation period. Owners affected cannot carry out the withdrawn PDR works without a planning application.
- Building Regulations
Building Regulations are statutory minimum standards for design and construction of buildings in England and Wales, covering structure, fire safety, ventilation, accessibility and energy efficiency. Approval is separate from Planning Permission and is administered by Local Authority Building Control or an Approved Inspector. Notifiable works such as electrical installations or window replacements can be self-certified by a member of a Competent Person Scheme like NICEIC or FENSA.
- Building Regulations Part P (Electrical Safety)
Part P of the Building Regulations requires that electrical work in dwellings in England and Wales is carried out safely and either self-certified by a competent person registered with an approved scheme or notified to and inspected by Local Authority Building Control. Notifiable work includes installation of a new circuit, replacement of a consumer unit (fuse board), and electrical work in bathrooms, kitchens or outdoors. Registered competent persons — such as NICEIC, NAPIT or ELECSA members — must issue a Part P compliance certificate after notifiable work. Failure to certify notifiable work can complicate property sales and insurance claims.
- Building Standards Scotland
Building Standards Scotland is the framework that regulates the design and construction of buildings in Scotland, operating separately from England and Wales Building Regulations. Approval is granted via a Building Warrant issued by the local authority Building Standards department before work starts. A Completion Certificate is then issued at the end. The Technical Handbooks are split into Domestic and Non-Domestic editions.
- Cavity Wall Insulation Grant
Cavity wall insulation fills the gap between a property's two outer walls to cut heat loss. UK government schemes — currently the Energy Company Obligation (ECO4) and the Great British Insulation Scheme — offer grants or fully funded installation to eligible households, typically those on certain benefits or in lower-rated EPC homes. Installation should be carried out by a CIGA-guaranteed or TrustMark-registered installer, and a 25-year CIGA guarantee is standard.
- CDM Regulations 2015
The Construction (Design and Management) Regulations 2015 set out the health and safety duties for everyone involved in a construction project. For notifiable projects — those lasting more than 30 working days with more than 20 workers simultaneously, or exceeding 500 person-days — a Principal Designer and Principal Contractor must be formally appointed and a Construction Phase Plan and Health and Safety File produced. The client must notify the HSE using an F10 notification before notifiable work begins. All clients, designers and contractors have duties regardless of project size. CDM aims to ensure health and safety is considered at every stage from design through to eventual demolition.
- Common Parts (Leasehold)
In a leasehold building, the common parts are the shared areas that no single leaseholder owns outright — entrance halls, staircases, lifts, corridors, roofs, gardens and external walls. The freeholder or a management company is usually responsible for maintaining them, with costs recovered from leaseholders through the service charge. Disputes over common-parts upkeep and charges can be referred to the First-tier Tribunal (Property Chamber).
- Conveyancing
Conveyancing is the legal process of transferring property ownership from seller to buyer. It is handled by a solicitor or licensed conveyancer who carries out local-authority and environmental searches, reviews contracts and the title, manages exchange of contracts and completion, and registers the new owner with HM Land Registry. The process also handles Stamp Duty payment. Typical residential conveyancing takes 8 to 12 weeks, and the buyer becomes legally committed only at exchange of contracts.
- Council Tax Bands
Council Tax bands (A to H in England and Scotland, A to I in Wales) determine how much Council Tax a household pays, based on the property's estimated value on a fixed valuation date — 1 April 1991 in England. The Valuation Office Agency sets the band, and the local council sets the rate for each band annually. Households can challenge their band if they believe it is wrong, though a successful challenge can also raise neighbours' bands. Band determines a charge, not the property's current market value.
- Damp Proof Course (DPC)
A damp proof course (DPC) is a horizontal barrier built into a wall near ground level to stop rising damp — moisture drawn up from the ground through masonry. Modern buildings use a plastic or bituminous membrane; older properties may have slate, or none at all, and can be retrofitted with an injected chemical DPC. Failed or bridged DPCs are a common cause of damp and are routinely flagged in home surveys.
- EICR
An Electrical Installation Condition Report (EICR) is a formal assessment of the safety of a property's fixed electrical installation, carried out by a qualified electrician. It identifies defects, deterioration and non-compliance with BS 7671 wiring regulations, classifying issues from C1 (danger present) to C3 (improvement recommended). Since 2020, private landlords in England must obtain an EICR at least every five years and provide it to tenants. It differs from an EPC, which rates energy efficiency rather than electrical safety.
- EICR (Electrical Installation Condition Report)
An Electrical Installation Condition Report (EICR) is a formal periodic inspection of a property's fixed electrical wiring, accessories and consumer unit, carried out by a qualified electrician against BS 7671 wiring regulations. Since 1 April 2021, landlords in England must obtain an EICR at least every five years for all rental properties and provide a copy to tenants and to the local authority on request. The report classifies observations as C1 (danger present — immediate action required), C2 (potentially dangerous), C3 (improvement recommended) or FI (further investigation needed). A result is classed as Unsatisfactory if it contains a C1, C2 or FI code.
- EPC (Energy Performance Certificate)
An Energy Performance Certificate rates a building's energy efficiency from A (best) to G (worst). EPCs are mandatory for properties when sold, let or constructed and remain valid for 10 years. Since April 2020, privately rented homes in England and Wales must achieve at least an E rating unless an exemption applies. EPCs are produced by accredited Domestic or Non-Domestic Energy Assessors.
- EPC bands
EPC bands are the seven A-G ratings on an Energy Performance Certificate, based on a SAP or RdSAP score from 1 to 100+. A is most efficient (92+) and G is least (1-20). Domestic privately rented properties in England and Wales must reach E or higher under MEES; proposed reforms would raise this to C for new tenancies. Lender Energy Efficiency Schemes increasingly reference EPC bands directly.
- EPC Rating (A-G Scale)
An Energy Performance Certificate (EPC) rating is an A-to-G assessment of a property's energy efficiency, produced by an accredited energy assessor. The rating is based on a SAP score: A is most efficient (92+) and G is least (1-20). EPCs are legally required when a property is built, sold or rented and are valid for 10 years, though a new assessment can be commissioned sooner if improvements have been made. The rating directly affects rental eligibility under MEES regulations, influences mortgage products and green finance eligibility, and gives buyers and tenants an indication of future energy costs.
- Estate Management
Estate management refers to the ongoing administration of communal property — leasehold blocks, freehold estates with shared roads or amenities, and mixed-tenure developments. Managing agents are typically ARMA or RICS regulated and are paid through service charges or estate rentcharges. Freehold "fleecehold" estate charges have prompted calls for statutory regulation.
- Freehold vs Leasehold
Freehold and leasehold are the two main forms of property ownership in England and Wales. A freeholder owns the building and the land it stands on outright, with no time limit. A leaseholder owns the right to occupy a property for a fixed term (often 99 to 999 years) but not the land, and pays ground rent and service charges to the freeholder. Most flats are leasehold while most houses are freehold. Leaseholders can sometimes extend the lease or buy the freehold collectively.
- Gas Safety Certificate (CP12)
A Gas Safety Certificate, often called a CP12, is an annual safety inspection record required by law for all rented residential properties in the UK. It must be carried out by a Gas Safe registered engineer, who checks all gas appliances, pipework and flues in the property. Landlords must provide a copy to existing tenants within 28 days of the check and to new tenants before they move in. The record must be retained for at least two years. Failure to obtain a valid gas safety certificate is a criminal offence and can also invalidate the ability to serve a valid Section 21 notice.
- Gazumping & Gazundering
Gazumping and gazundering are risks of the English and Welsh property system, where deals are not legally binding until exchange of contracts. Gazumping is when a seller accepts a higher offer from another buyer after already accepting one, leaving the original buyer to lose their offer and any costs incurred. Gazundering is the reverse: a buyer reduces their offer at the last minute, pressuring the seller who is committed to a chain. Neither is illegal, which is why fast conveyancing reduces exposure.
- Ground Rent
Ground rent is the annual sum a long leaseholder pays the freeholder under the terms of a lease. Since June 2022, new long residential leases in England and Wales must be at a peppercorn (zero monetary value) ground rent. Pre-existing leases can still levy escalating ground rents, though these have come under regulatory scrutiny. Non-payment can trigger lease forfeiture.
- Help to Buy: Equity Loan
Help to Buy: Equity Loan was a government scheme that provided an interest-free equity loan of 20% of a new-build property's purchase price (40% in London) to first-time buyers with at least a 5% deposit, enabling them to obtain a 75% mortgage. The England scheme closed to new applications in October 2022 and final completions ended in March 2023. The loan is repayable on sale, full repayment or remortgage, or at the end of the 25-year term, at the prevailing percentage of the property's market value. Interest is charged from year six onwards, starting at 1.75% and rising annually.
- HMO Licence
A House in Multiple Occupation (HMO) licence is required by landlords renting to multiple unrelated tenants who share facilities. Mandatory licensing applies to larger HMOs (generally five or more occupants forming two or more households), while many councils operate additional licensing for smaller HMOs. Licences set standards for room sizes, amenities, fire safety and management. Renting an unlicensed HMO that needs a licence is a criminal offence and can lead to rent-repayment orders and fines.
- HomeBuyer Report vs Building Survey
When buying a property, two main survey levels are offered. A HomeBuyer Report (RICS Level 2) is a mid-level inspection suitable for conventional properties in reasonable condition, flagging visible problems and giving a market valuation. A Building Survey (RICS Level 3, formerly a full structural survey) is a detailed inspection appropriate for older, larger or altered properties, examining construction and advising on repairs. Choosing the right level depends on the property's age and condition, not just price.
- Land Transaction Tax (LTT)
Land Transaction Tax (LTT) is the Welsh equivalent of Stamp Duty Land Tax in England, levied on purchases of land and property in Wales. It is administered by the Welsh Revenue Authority rather than HMRC and has different rate bands and thresholds from SDLT. From July 2024 the nil-rate threshold for residential property is £225,000. First-time buyer relief applies up to £500,000. Additional property surcharges apply at 4% on top of standard rates. Buyers have 30 days from completion to submit an LTT return and pay any tax due to the Welsh Revenue Authority.
- Leasehold Reform
Leasehold reform refers to the package of legislation modernising long residential leases in England and Wales. The Leasehold Reform (Ground Rent) Act 2022 banned new ground rents above a peppercorn; the Leasehold and Freehold Reform Act 2024 extended lease-extension rights and abolished marriage value. Further consultation on commonhold and existing ground rents continues.
- Listed Building Consent
Listed building consent is a separate permission, additional to planning permission, required before altering, extending or demolishing a building listed for its special architectural or historic interest. Buildings are graded I, II* or II in England and Wales. Carrying out unauthorised works to a listed building is a criminal offence. Applications are decided by the local planning authority, often with input from Historic England.
- MEES (Minimum Energy Efficiency Standards)
The Minimum Energy Efficiency Standards (MEES) prohibit landlords in England and Wales from letting properties with an EPC rating below E, unless a registered exemption applies. Non-domestic properties have been in scope since 2018, domestic since 2020. Civil penalties of up to £150,000 per non-domestic breach are enforced by local authorities. Future tightening to band C is under consultation.
- MEES (Minimum Energy Efficiency Standards) Regulations
The Minimum Energy Efficiency Standards (MEES) Regulations prohibit landlords in England and Wales from letting domestic properties with an EPC rating below E without a registered exemption. The regulations have applied to new tenancies since April 2018 and all tenancies since April 2020. Government consultation proposes raising the minimum to a C rating for new tenancies by 2028 and all tenancies by 2030, subject to legislation. Landlords face civil penalties of up to £5,000 per dwelling per breach, enforced by local authorities. Exemptions — such as a third-party consent exemption or a high-cost exemption — must be registered on the PRS Exemptions Register.
- Part P Electrical Work
Part P of the Building Regulations governs the safety of electrical installations in dwellings in England and Wales. Certain "notifiable" work — such as new circuits or work in bathrooms — must either be carried out by an electrician registered with a Competent Person Scheme (e.g. NICEIC, NAPIT, STROMA) who self-certifies it, or be notified to and inspected by building control. Compliant work is recorded with an electrical installation certificate.
- Permitted Development Rights (PDR)
Permitted Development Rights (PDR) allow certain types of building work in England to be carried out without a full planning application, under rights granted by Parliament in the Town and Country Planning (General Permitted Development) Order 2015. Typical permitted works include single-storey rear extensions (up to 4m for detached houses), loft conversions within volume limits, outbuildings and some changes of use. PDR is restricted or removed in Conservation Areas, Areas of Outstanding Natural Beauty, National Parks and for listed buildings. Local authorities can also remove specific PDR through an Article 4 Direction. Some larger extensions require prior approval from the local planning authority.
- Planning Permission
Planning Permission is consent from a Local Planning Authority for development that materially changes a property or land use. Many small projects fall under Permitted Development Rights and need no application. Larger extensions, new builds and changes of use require a Full Planning application, with a statutory eight-week determination period. Refusals can be appealed to the Planning Inspectorate.
- RICS Home Survey Level 2/3
The RICS Home Survey Standard defines three levels of residential survey. Level 1 (Condition Report) is a basic visual inspection; Level 2 (HomeBuyer Report) covers most modern homes in reasonable condition; Level 3 (Building Survey) is the most detailed and suits older, larger or altered properties. All three must be carried out by a RICS-registered surveyor.
- RICS HomeBuyer Report (Level 2)
The RICS HomeBuyer Report (Survey Level 2) is a standardised RICS survey format suited to conventional residential properties in reasonable condition built after approximately 1900. It reports condition ratings of 1 (no repair needed), 2 (defects needing attention) or 3 (urgent or serious defects) for each element, highlights significant issues affecting value, and often includes a market valuation. It is less detailed than a Level 3 Building Survey, which is recommended for older, unusual or substantially altered properties. All RICS Level 2 reports follow the RICS Home Survey Standard introduced in 2021.
- Right to Buy
Right to Buy is a government scheme allowing eligible council tenants in England to buy their home at a discount based on how long they have been a public-sector tenant. Discounts are capped and subject to regional limits, and buyers who sell within a defined period must repay part of the discount. The scheme has been ended in Scotland and Wales. Comparable but more limited Right to Acquire arrangements apply to some housing-association tenants.
- Right to Rent
Right to Rent is the UK Home Office scheme requiring private landlords in England to check that all prospective adult tenants have a legal right to rent before granting a tenancy agreement. Landlords must verify original identity documents, use the Home Office online checking service for those with e-visas, or use a certified Identity Service Provider. Repeat checks must be carried out for those with time-limited leave to remain. Landlords who fail to carry out proper checks, or who continue renting after becoming aware of an illegal tenant, face civil penalties of up to £20,000 per occupier for a first breach and unlimited fines thereafter, plus potential criminal prosecution.
- Selective Licensing
Selective licensing is a scheme under which a council requires all private landlords in a designated area to obtain a licence for rented homes, regardless of whether they are HMOs. It is used to tackle low housing demand, anti-social behaviour or poor property conditions in specific neighbourhoods. Each designation lasts up to five years and sets management and property-condition standards. Landlords should check the local authority's map, as boundaries can change street by street.
- Service Charge
Service charge is the variable contribution leaseholders pay towards the cost of maintaining a block — buildings insurance, repairs, cleaning, gardening and management. The Landlord and Tenant Act 1985 requires service charges to be reasonable and lets leaseholders challenge them at the First-tier Tribunal. Consultation is mandatory for major works exceeding £250 per leaseholder.
- Service Charge (Leasehold)
A leasehold service charge is the variable annual sum leaseholders pay to the freeholder or managing agent to cover the cost of maintaining and insuring the building and its communal areas. Under the Landlord and Tenant Act 1985, service charges must be reasonable, and leaseholders may challenge unreasonable charges at the First-tier Tribunal (Property Chamber). Landlords must consult leaseholders before committing to major works costing more than £250 per leaseholder (the Section 20 consultation process). Managing agents and freeholders must provide an annual summary of costs with the service charge demand, along with a summary of leaseholders' rights.
- Share of Freehold
Share of freehold means the leaseholders of a building (typically flats) collectively own the freehold, usually through a company in which each flat owner holds a share. This gives owners control over service charges, maintenance and lease extensions without needing a separate freeholder's consent. It is generally seen as preferable to standard leasehold because residents manage the building themselves, though it brings shared responsibility for repairs and decisions.
- Shared Ownership
Shared ownership is an affordable home-ownership scheme where a buyer purchases a share of a property (typically between 10% and 75%) and pays subsidised rent to a housing association on the remaining share. Buyers can later increase their share through a process called staircasing, sometimes up to 100%. Properties are usually leasehold, and owners are responsible for service charges and often full repair costs even on the part they do not own. It lowers the deposit and mortgage needed to get on the ladder.
- Stamp Duty Land Tax
Stamp Duty Land Tax (SDLT) is a tax paid by buyers of property or land in England and Northern Ireland above a threshold (Scotland uses Land and Buildings Transaction Tax, Wales uses Land Transaction Tax). It is charged in tiered bands on the portion of the price falling within each band, with surcharges for additional properties and reliefs for first-time buyers. The buyer's conveyancer normally calculates and submits the SDLT return and payment to HMRC within 14 days of completion.
