Heat pump funding in Birmingham
Multiple stacking incentives apply to commercial heat pump installations in Birmingham in 2026.
100% first-year tax relief
Heat pump systems qualify as plant and machinery for the Annual Investment Allowance — 100% of capex deducted from corporation tax in Year 1. A £150,000 heat pump installation delivers a £37,500 tax saving at 25% corporation tax. No cap, permanent, applies to all qualifying commercial heat pump types.
Interest-free loans for public sector
NHS trusts, schools, councils and universities in Birmingham can access Salix BAU interest-free loans for heat pumps. Repaid from energy savings over 5–12 years. Open-ended and accepting applications now. PSDS Phase 4 closed November 2024 but Salix BAU continues — no end date.
Zero VAT with renewable system
Heat pumps installed as part of a renewable energy system (e.g. alongside solar PV) qualify for 0% VAT on supply and installation. Standalone commercial heat pump VAT eligibility depends on installation context — we assess qualification case-by-case to maximise VAT recovery.
Solar-powered heating at near-zero cost
A solar + heat pump system in Birmingham uses daytime PV generation to power the heat pump compressor at near-zero marginal cost. Every 1 kWh of solar produces 3.5–5 kWh of useful heat (CoP 3.5–5.0). Particularly effective in Birmingham buildings with continuous heating demand — hospitals, leisure centres, food production.
Heat pump types for Birmingham commercial buildings
Most common commercial installation in Birmingham. Extracts heat from outdoor air — effective down to -15°C with modern units. Low installation disruption. No ground works required. Suited to offices, retail, warehouses and healthcare buildings.
Higher CoP than ASHP, particularly in winter. Requires ground loop installation — open land or borehole drilling. Suited to Birmingham sites with available land (rural fringe, business parks, hospitals). More capital-intensive but lower running costs.
Delivers flow temperatures up to 75°C — compatible with existing radiator systems without full fabric upgrades. Enables direct boiler replacement in Birmingham older commercial buildings without refurbishment. Increasingly cost-competitive as grid and boiler gas prices diverge.
250 kWp solar + 200 kW ASHP for a Birmingham office/industrial building
- • 250 kWp rooftop solar: ~£175,000

Funding by asset class
The allowance depends on the asset, and most pages on this topic get it the wrong way round. Solar PV is special-rate expenditure (HMRC Capital Allowances Manual CA22335), so the 100% year-one route is the Annual Investment Allowance — Full Expensing is a main-rate measure and does not reach it. Battery storage, EV charging and heat pumps are main-rate plant, so Full Expensing genuinely does apply to those.
- commercial heat pump costs and payback
Main-rate plant, so Full Expensing does apply here.
- financing commercial battery storage
Main-rate plant. Stacks with solar for self-consumption.
- commercial solar pricing by system size
Capex bands per kWp before any relief.
- solar for industrial units and warehouses
Large roofs, high daytime load — the strongest case.
- how AIA works on commercial solar capex
Solar is special-rate, so AIA is the 100% year-one route.
Find out which 2026 schemes your site actually qualifies for
- 1. A short written funding note naming every scheme your site qualifies for in 2026 — and the ones it does not.
- 2. Indicative system size and a capex band for your roof.
- 3. Year-one tax treatment per asset in £ — solar is special-rate expenditure, so the route is the Annual Investment Allowance; battery storage and heat pumps are main-rate plant, where Full Expensing does apply. Most pages get this the wrong way round.
- 4. Projected SEG export revenue at current rates.
- 5. Any red-flag eligibility or DNO issues we can see up front.
Covers solar PV, battery storage, EV charging and commercial heat pumps — separately or as one bundled project. If your project is a heat pump or a battery rather than a roof, say so in the message box and the note is written against that asset instead.
