Commercial Energy
Efficiency Packages UK
Solar PV, LED lighting, heat pumps, battery storage, EV charging and smart controls — bundled into a single grant-funded project for UK commercial buildings. One survey, one contract, one application. Net cost typically 40–55% of gross capex after the Annual Investment Allowance and 0% VAT.
How grants apply to energy efficiency
Free energy audit
We review your energy bills, EPC rating, and building services to identify which measures deliver the fastest payback and largest grant coverage. Output: prioritised measure list with costings.
Bundle for maximum incentives
0% VAT applies to solar, heat pump and insulation together. The Annual Investment Allowance covers all plant and machinery in one Year 1 CT claim. OZEV WCS covers EV chargers. One invoice, maximum incentives.
Single contractor delivery
Our MCS-certified delivery partners install all measures under one contract — solar, BESS, heat pump, LED, EV charging. One mobilisation, one commissioning, one warranty package.
Why bundle measures into one project
Bundling qualifies for maximum grant stacking — 0% VAT, the Annual Investment Allowance, OZEV WCS — while reducing mobilisation cost through a single contractor visit.
Foundation measure. 0% VAT, the Annual Investment Allowance, SEG export income. Co-location with BESS and heat pump compounds savings.
Fast standalone payback (3–5 yr). AIA-eligible. Reduces heat load from lighting, improving HVAC efficiency downstream.
Annual Investment Allowance, Salix Finance (public sector), 0% VAT with solar co-location. Solar-powered heat at near-zero marginal cost.
0% VAT co-located with solar. The Annual Investment Allowance. BESS captures midday solar surplus for evening demand peaks and time-of-use arbitrage.
OZEV WCS (£14,000/site), EVIG (75% fleet depot), the Annual Investment Allowance on remainder. Solar shifts charging to daylight hours automatically.
BMS optimisation, occupancy-based control, demand response. The Annual Investment Allowance. No structural changes — software and sensor upgrades.

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.
- what a commercial heat pump actually costs in 2026
Main-rate plant, so Full Expensing does apply here.
- what commercial battery storage costs per kWh
Main-rate plant. Stacks with solar for self-consumption.
- the real cost of a commercial solar install
Capex bands per kWp before any relief.
- industrial rooftop solar economics
Large roofs, high daytime load — the strongest case.
- claiming the Annual Investment Allowance on solar
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.
