Aberdeen Heat & Power is a not-for-profit organisation established by Aberdeen City Council to tackle fuel poverty through affordable district heat - appointed us as lead technical consultant to decarbonise and expand the existing Hazlehead heat network. The scheme combines air source heat pumps with an innovative waste heat offtake from a nearby crematorium, supplying heat to sheltered housing, residential properties, local businesses, and the new Hazlehead Academy campus. We secured Scottish Heat Network Fund grant support and the project is currently under construction.
Appointed initially for feasibility in 2024, we developed an innovative low carbon technical solution, built the business case, secured SHNF grant funding, and delivered full RIBA Stage 4 design across four procurement lots. We are now engaged as Client Engineer, Contract Manager, and Principal Designer throughout construction and delivery, managing grant submissions and overseeing commissioning and handover.
Scope
We were appointed by Aberdeen Heat & Power as lead technical consultant to undertake a feasibility assessment for the decarbonisation and expansion of the Hazlehead heat network, developing an innovative solution combining crematorium waste heat offtake and ASHPs to RIBA Stage 2. We developed a detailed business case and completed a successful Scottish Heat Network Fund grant application to part-fund the new low carbon energy centre and network expansion.
Following the successful SHNF award in 2025, we developed full RIBA Stage 4 design packages across four separate procurement lots - covering the containerised energy centre, heat pump supply, heat network pipework, and main contractor M&E works - including hydraulic modelling, P&IDs, electrical design, equipment specifications, Employer's Requirements, and tender documentation for each.
We provided procurement support and tender evaluation across all lots before transitioning into our current role as Client Engineer, Contract Manager, and Principal Designer under CDM 2015, overseeing construction, managing monthly SHNF grant submissions, and progressing the scheme through to commissioning and handover.

Solution
A technically innovative solution that combines waste heat recovery from an adjacent crematorium with air source heat pumps and a containerised backup energy centre - maximising use of available local heat sources to minimise carbon emissions and operating costs. The scheme was procured across four separate lots to optimise contractor specialisms and value, with the entire design, funding, procurement, and construction programme managed within the stringent timescale requirements of the SHNF grant funding conditions.
“Aberdeen has many waste heat sources available across the city and the Hazlehead project is just the beginning of the ambitions that AHP have to capture waste heat to deliver affordable low carbon heat through its existing network to homes and businesses across the city”.
