Trade Certification

BAFE is the independent third-party certification register for fire safety service providers in the UK. Separate BAFE schemes cover fire risk assessment (SP205), fire detection and alarm systems (SP203-1), portable extinguishers (SP101), emergency lighting (SP203-4) and more. Many insurers, public-sector buyers and Responsible Persons under the Regulatory Reform (Fire Safety) Order specify BAFE-certified providers.

CERTASS is a UK Competent Person Scheme for window, door, conservatory and roofline installers in England and Wales. CERTASS-registered companies can self-certify compliance with Building Regulations for replacement glazing, issuing the customer an Installation Certificate. It is the principal alternative to FENSA in the fenestration sector.

CHAS (the Contractors Health and Safety Assessment Scheme) is one of the UK's leading health-and-safety pre-qualification schemes for contractors. Achieving CHAS accreditation shows a business meets recognised health-and-safety standards and is often a prerequisite for tendering on public-sector and large commercial contracts. It is a founding member of SSIP (Safety Schemes in Procurement), so a CHAS certificate is mutually recognised by other SSIP member schemes.

The CITB (Construction Industry Training Board) is the statutory skills body for the British construction industry. It collects a levy from larger construction employers and reinvests it as training grants. CITB also administers the Health, Safety and Environment (HS&E) test that workers must pass to obtain a CSCS card. Apprenticeships, qualifications and standards across many trades are underpinned by CITB funding and frameworks.

F-Gas certification is required for any UK technician or business working with stationary refrigeration, air-conditioning and heat-pump equipment containing fluorinated greenhouse gases. The Fluorinated Greenhouse Gases Regulations 2015 mandate that engineers hold a Category I-IV qualification and that companies are F-Gas certified by a body such as Refcom or Quidos. Records of each charge, leak check and recovery must be kept for five years.

FENSA (Fenestration Self-Assessment Scheme) is the largest Competent Person Scheme for replacement windows and doors in England and Wales. Installers registered with FENSA can self-certify compliance with Building Regulations, avoiding the need for separate local-authority sign-off. A FENSA certificate is issued to the homeowner and is requested by buyers during a property sale. Alternatives include CERTASS and Assure.

Before joining the Gas Safe Register, a gas engineer must hold a current ACS (Accredited Certification Scheme) qualification, which includes a core gas safety assessment (CCN1 for domestic) plus appliance-specific modules such as boilers (CENWAT) or cookers (CKR1). Certificates are renewed every five years through reassessment. The assessment proves practical competence and underpins legal registration; it is sometimes referred to alongside the Gas Industry Accident Reporting (RIDDOR) duties engineers must follow.

Gas Safe Register is the official UK list of engineers qualified to work legally and safely on gas appliances. It replaced CORGI in 2009 and is mandatory for any tradesperson installing, servicing or repairing gas boilers, fires or pipework. Each engineer carries a photo ID card with a unique licence number. Consumers can verify an engineer on the Gas Safe Register website before allowing work to begin.

HETAS is the UK Competent Person Scheme for solid-fuel and biomass heating — wood-burning stoves, multi-fuel appliances, flues and chimneys. HETAS-registered installers can self-certify Building Regulations compliance, avoiding a Local Authority Building Control application. The scheme also operates an appliance approval list used by Defra for smoke-control areas.

The Microgeneration Certification Scheme is the UK standard for low-carbon energy technology installations of up to 50kW electrical or 45kW thermal. MCS-certified installers can register heat pumps, solar PV, biomass boilers and small wind turbines. Registration is a prerequisite for the Smart Export Guarantee and the Boiler Upgrade Scheme. MCS is owned by a not-for-profit MCS Service Company.

NAPIT (National Association of Professional Inspectors and Testers) is a multi-trade Competent Person Scheme covering electrical, plumbing, heating, ventilation and renewables. Members can self-certify Part P electrical work and similar notifiable installations. NAPIT is a direct alternative to NICEIC for electricians and is recognised by Building Control across England, Wales and Scotland.

NICEIC is the UK's leading electrical certification body, assessing contractors against BS 7671 wiring regulations. Approved Contractors and Domestic Installers pass an annual technical assessment of a sample of completed work. A NICEIC registration is widely accepted as proof of competence for Part P notifiable works in dwellings. Other recognised electrical schemes include NAPIT, STROMA and ELECSA.

OFTEC (Oil Firing Technical Association) is the trade body and Competent Person Scheme for the oil heating industry across the UK and Ireland. OFTEC-registered technicians can self-certify installations of oil boilers, tanks and renewable-liquid-fuel appliances. The scheme is recognised under Building Regulations for notifiable oil-heating work. Around 11,000 technicians are currently registered.

PAS 2030 is the publicly available specification for installation of energy-efficiency measures in existing dwellings. Installers must be PAS 2030 certified to deliver work under government-funded schemes such as ECO and the Great British Insulation Scheme. The companion PAS 2035 standard covers whole-house retrofit assessment, design and coordination. Certification is issued by UKAS-accredited certification bodies.

PAT (Portable Appliance Testing) is the routine inspection of plug-in electrical equipment to verify it is safe to use. The Health and Safety Executive requires employers, landlords and event organisers to maintain electrical equipment in safe condition; PAT testing is the most common evidenced approach. Test intervals vary by appliance class and environment, from three months for site tools to four years for office IT. Testers should be competent — typically City & Guilds 2377 qualified.

Solid fuel installers fit and service wood-burning stoves, biomass boilers, open fires and chimneys. HETAS is the official body that registers competent solid-fuel and biomass installers in the UK, allowing them to self-certify work under Building Regulations (notably Part J on combustion appliances and flues). A HETAS certificate gives homeowners assurance the appliance was installed safely and that carbon-monoxide and flue requirements were met.

STROMA Certification operates UKAS-accredited schemes for energy assessors (Domestic and Non-Domestic EPC, SAP, SBEM) and Competent Person Schemes for electricians and microgeneration installers. STROMA-certified members can lodge EPCs and self-certify electrical work. The scheme is widely used by independent energy assessors operating outside Elmhurst or Quidos.

TrustMark is the UK government-endorsed quality scheme for tradespeople working in or around the home. Membership requires passing technical, customer-service and trading-standards checks via an approved Scheme Provider. TrustMark is the gateway certification required to deliver work under several government grants, including ECO and the Great British Insulation Scheme. The scheme covers more than 70 trades from roofing to renewable energy.

A TrustMark-approved trader is a business registered under the UK government-endorsed TrustMark scheme, which vets tradespeople working in and around the home for technical competence, customer service standards, trading practices and appropriate insurance. Registration is delivered through approved Scheme Providers such as FENSA, Gas Safe and the NHBC. TrustMark registration is a mandatory requirement for accessing certain government-funded home improvement schemes, including ECO4, the Great British Insulation Scheme and the Boiler Upgrade Scheme. Consumers can search for approved businesses at trustmark.org.uk and submit complaints through the TrustMark dispute process.

Water Regulations Approval verifies that plumbing fittings and appliances comply with the Water Supply (Water Fittings) Regulations 1999, designed to prevent waste, contamination and misuse. The WRAS Approved Material and Product schemes are the principal route to compliance in England, Wales, Scotland and Northern Ireland. Installers should be on the WaterSafe register, the umbrella body for approved plumbing contractor schemes.

WaterSafe is the free online directory of approved plumbers across the UK, run by water suppliers and approved contractor schemes. Inclusion requires membership of an Approved Contractor Scheme (e.g. APHC, CIPHE, WIAPS), which entails technical assessment and compliance with the Water Fittings Regulations. Consumers can search by postcode to find an approved plumber for notifiable plumbing work.
