Preparing for Local Authority Solar Tenders and Heat Pump Tenders – Warm Homes Plan 2026

Solar tenders are on increasingly common especially as the UK Government’s newly launched Warm Homes Plan represents a historic shift in national infrastructure. Backed by a monumental £15 billion public investment, it is the most ambitious home upgrade programme in British history, with incredibly clear objectives: upgrade 5 million homes by 2030, triple the number of rooftops with solar panels, and deliver 450,000 heat pump installations per year.

It deploys capital primarily through two major streams: 

The Warm Homes: Social Housing Fund: Building upon the legacy of the SHDF, this £1.3 billion fund allows social housing providers to execute large-scale, street-by-street retrofit programmes.

The Warm Homes: Local Grant: With an initial allocation of £500 million, the Local Grant empowers councils to deliver fully funded energy performance upgrades to low-income, privately owned, and privately rented households. The focus is specifically on properties with an Energy Performance Certificate (EPC) rating of D or below. 

For renewable energy providers, this is an unprecedented commercial opportunity especially when it comes to solar tenders. The government is rapidly moving away from fragmented, legacy funding models and instead channelling billions directly through local authorities and housing associations. However, with such lucrative frameworks entering the market, contracting authorities are demanding strict compliance, robust supply chains, and extensive social value.

Why Was the Legislation Introduced?

The plan was introduced to tackle three pressing national crises simultaneously: high energy bills, fuel poverty, and climate change.

Despite improvements over the last decade, millions of UK homes remain poorly insulated and heavily reliant on expensive fossil fuels. The Warm Homes Plan aims to lift at least one million families out of fuel poverty by upgrading their homes to a minimum EPC rating of C. Furthermore, the initiative is a cornerstone of the UK’s legal commitment to achieving net-zero carbon emissions, heavily incentivising the transition away from gas boilers toward air source heat pumps and domestic solar PV generation.

Impact on the Industry and Relevant Organisations

This sweeping legislation fundamentally changes the landscape for several key stakeholders:

Renewable Energy Solution Providers: For solar tenders, battery storage, and heat pump installers, the plan guarantees a massive, sustained pipeline of work. However, the barrier to entry has been raised; providers can no longer rely purely on price to win contracts. They must now operate at an industrial scale while maintaining strict regulatory compliance.

Local Authorities and Housing Associations: Councils and social landlords have transitioned from bidding for short-term funding pots to managing vast, multi-year retrofit budgets. They are now tasked with identifying eligible households, managing complex procurement frameworks, and ensuring works are delivered compliantly.

When evaluating social housing tenders, contracting authorities are placing significant weight on tenant welfare. Technical skill is only half the battle. Bidders must write compelling methodologies detailing how they will communicate with vulnerable tenants, minimise disruption during invasive installations, and prevent post-installation issues like damp and mould.

How it Influences Social Housing and Solar Tenders

The Warm Homes Plan completely dictates the structure of modern public sector energy tenders. Contracting authorities are now procuring through the lens of this legislation, which influences tenders in three primary ways:

1. Mandatory Compliance (PAS 2035 & MCS): Evaluators will instantly reject non-compliant bids. Tenders now explicitly demand that all works align with the PAS 2035 ‘Whole-House Retrofit’ standard. Furthermore, maintaining valid Microgeneration Certification Scheme (MCS) accreditation is a strict legal requirement for drawing down this public funding.
2. Tenant Liaison and Safeguarding: In social housing tenders, technical skill is only half the battle. Bidders must write compelling methodologies detailing how they will communicate with vulnerable tenants, minimise disruption during invasive heat pump installations, and prevent post-installation issues like damp and mould.
3. Social Value: Because the plan aims to create 180,000 green jobs, tenders heavily weigh Social Value. Winning bids must prove a commitment to hiring local workers, offering apprenticeships, utilising UK-made manufacturing supply chains, and actively combating regional fuel poverty. Further commitments, such as paying the Real Living Wage, sponsorship of local community projects, and voluntary work are also well valued.

How Renewable Energy Providers Can Prepare for Solar Tenders

Winning these lucrative contracts begins long before the tender is officially released. To ensure your organisation is ‘bid-ready,’ you must proactively prepare the following elements:

• Secure Crucial Certifications: Ensure your NICEIC, NAPIT, and MCS accreditations are entirely up to date. You must also hold PAS 2030 certification as an installer and ensure your business is registered with TrustMark, the government-endorsed quality scheme. It is highly beneficial to establish early partnerships with qualified PAS 2035 Retrofit Assessors and Coordinators, as their oversight is mandatory for these funded projects.
• Compile a Robust Documentation Library: Prepare a comprehensive bank of internal documentation, including up-to-date Health and Safety policies, Risk Assessments and Method Statements (RAMS), and stringent Modern Slavery, Safeguarding, and GDPR policies.
• Gather Social Value Evidence: Begin collating hard data on your previous social value initiatives. Gather case studies detailing the number of apprentices you have trained, statistics on your local supply chain spend, and verifiable metrics on how your installations have previously reduced resident energy bills.
• Solidify Supply Chain Agreements: With the government’s push for UK-manufactured technology, you must secure robust, written agreements with your suppliers. Having documented proof that you can reliably source heat pumps, solar panels, and battery storage from UK manufacturers/suppliers without delays will set your bid apart from competitors.
• Prioritise Accessibility and Resident Liaison: Social housing providers demand strict adherence to accessibility standards. Prepare methodologies showing how you accommodate diverse communication needs. This includes providing handover packs in easy-read formats or translated materials, and training your engineers to respect the specific sensory, learning, or physical requirements of individual tenants during installations.
