What the Combined Re-Roof + Solar Bundle delivers
For pre-2000 farm buildings with asbestos cement cladding, combined re-roof + PV is the standard solution. HSE-licensed asbestos removal followed by profiled steel re-cladding followed by PV install on the new roof — delivered as a single coordinated project.
Standard Combined Re-Roof + Solar Bundle scope
Standard combined re-roof + PV scope: HSE-licensed asbestos cement removal (£30-50/sqm); profiled steel re-cladding (£45-80/sqm); structural reinforcement where required; 100-500 kW PV on the new roof. Total project typically 6-9 months including all asbestos paperwork, planning consultation, DNO G99 connection.
Economics in 2026 prices
For a typical 2,000 sqm re-roof + 250 kW PV: re-roof £75,000-£130,000 + asbestos removal £60,000-£100,000 + PV £200,000 = total £335,000-£430,000. The PV portion (~£200,000) qualifies for 100% AIA. The re-roof and asbestos portions typically don't (building fabric, not plant and machinery). Net year-one tax saving on PV element: ~£50,000. Combined annual saving: £40,000+ from PV. Simple payback (PV only): 4 years; combined business case (including re-roof): 8-10 years — but unlocks buildings otherwise unusable for PV.
Why we deliver as a single project
The Combined Re-Roof + Solar Bundle works because all components are designed, procured, and installed as one coordinated project. Single G99 grid connection application. Single monitoring portal. Single set of warranties. Single contractual relationship. Compared to running multiple separate projects, the bundled approach saves £20,000-£60,000 in mobilisation overhead alone.

Common questions
What's the total capex for a typical Combined Re-Roof + Solar Bundle?
Varies by farm scale. Most installs range £80,000-£500,000+. We deliver fixed-price proposals within 7 working days of receiving meter data.
Can the Combined Re-Roof + Solar Bundle be financed?
Yes — asset finance over 5-10 years for the entire bundle is typically EBITDA-positive from month one for installs with strong daytime baseload. PPA available for systems above 250 kW. Capital purchase with 100% AIA for incorporated farms.
How long does the bundle take from contract to commissioning?
Most bundles complete in 6-9 months from contract signature. The longest item is typically DNO G99 grid connection (6-14 months on most rural feeders, running in parallel). Physical install on-site is typically 4-8 weeks.
Is the bundle eligible for AIA tax relief?
Plant and machinery components (panels, inverters, batteries, EV chargers, heat pump units) are 100% AIA eligible up to the £1m annual cap. Building fabric (re-roofing, structural reinforcement) typically isn't but may have other tax treatment. We provide itemised invoices supporting clean accountant claim.
