KJ Tait is a chartered building services engineering consultancy delivering mechanical, electrical and public health (MEP) design alongside specialist sustainability and energy services across the UK. Our work spans the full building lifecycle, from early-stage planning and design through to commissioning, in-use performance and long-term decarbonisation.
The areas below reflect where we focus our technical expertise. Each service links through to more detailed information on how we work, the standards we apply and the type of results we deliver.
Decarbonisation strategies for new and existing buildings, aligned with UK net zero targets and local planning policy requirements.
Whole life carbon assessments covering embodied and operational emissions, using recognised methodologies such as RICS WLC and OneClick LCA.
Ongoing sustainability support embedded within project teams, helping coordinate design decisions, track outcomes and maintain focus on energy and carbon targets.
Dynamic simulation modelling using IES VE to assess overheating risk, optimise passive design strategies and support regulatory compliance including TM52 and TM59.
Operational energy modelling using CIBSE TM54 to provide realistic energy use predictions and inform design-for-performance strategies.
Detailed energy audits of existing buildings to identify inefficiencies, prioritise improvement measures and support cost and carbon reduction strategies.
SAP calculations for residential developments, supporting building regulations compliance and planning submissions.
Daylight and sunlight analysis to inform planning applications, support BREEAM requirements and improve occupant comfort.
Energy Performance Certificates for offices, retail and mixed-use buildings, with clear advice on ratings and opportunities for improvement.
Targeted upgrade strategies to achieve EPC B, combining building fabric improvements with building services and control optimisation.
Energy strategies, overheating assessments and sustainability statements to support planning submissions across England, Scotland and Wales.
Operational energy ratings based on measured in-use performance, assessed by accredited NABERS UK assessors.
Design-stage verification that proposed buildings can achieve targeted operational energy outcomes once in use.
BREEAM advisory and assessment support from concept through to final certification across a range of building types.
Certification support for digital connectivity and smart building infrastructure in commercial developments.
