What buyers expect in energy and decarbonisation tenders

Common UK requirements and references. The buyer's own documents always decide what is mandatory, so check the specification and selection questionnaire for each opportunity.

Standard or requirement Why it matters in the bid
MCS certification The Microgeneration Certification Scheme covers heat pumps and solar PV installers. Buyers and many funding schemes require it.
PAS 2035 and PAS 2030 The retrofit standards for domestic energy efficiency work, with TrustMark registration. Often required on housing retrofit contracts.
BS 7671 and electrical registration Wiring regulations for PV, battery and EV charging installations, with NICEIC or NAPIT registration commonly asked for.
F-gas certification Required for work on heat pumps and other equipment containing fluorinated refrigerants.
Grid connection (G98 and G99) Generation and storage must be notified to or approved by the distribution network operator, which can affect programme and cost.
Funding scheme conditions Public sector decarbonisation projects are often grant funded with fixed completion dates, reporting and evidence requirements.

Evidence to have ready

  • Installed projects of similar size with measured performance, such as heat pump efficiency or PV yield
  • Design capability, including heat loss calculations and system sizing
  • MCS, TrustMark, F-gas and electrical registrations
  • Experience of DNO applications and grid connection programmes
  • Approach to occupied buildings, phasing and heating outages
  • Carbon and energy savings methodology and post-installation monitoring

Quality questions you will often see

  • How will you design the system and evidence the expected savings?
  • How will you deliver within the funding deadline?
  • How will you manage grid connection and electrical capacity risks?
  • How will you keep buildings operating during installation?
  • How will you hand over, train staff and support performance afterwards?

Pricing risks to check

  • DNO connection costs and timescales outside your control
  • Electrical supply or distribution upgrades discovered after award
  • Roof structure, asbestos or access costs for PV
  • Grant funding deadlines with penalties or clawback for late completion
  • Equipment lead times and price movements

CPV codes we track

  • 09331000 Solar panels
  • 09332000 Solar installation
  • 71314200 Energy-management services
  • 45261215 Solar panel roof-covering work

Notices are also matched on title keywords, so buyers who choose a broad CPV code are still picked up.

Energy and decarbonisation tender questions

Straight answers for UK suppliers.

Where are decarbonisation tenders published?

Public sector heat pump, solar, LED and retrofit contracts are advertised on Find a Tender, with Scottish and Welsh notices also on Public Contracts Scotland and Sell2Wales. Many are let through frameworks, so check the frameworks page too.

Do I need MCS certification?

For heat pumps and solar PV it is commonly required by buyers and by grant funding conditions. Check the tender documents, and if you subcontract installation, make sure your installer holds it.

Why do decarbonisation projects have tight deadlines?

Many are funded by grants with fixed spend or completion dates, so buyers pass the deadline risk to contractors. Price and programme for it, and ask early about what happens if grid connection is delayed.
