Who it's for Homeowners replacing oil, LPG or older gas heating; homeowners with south- or west-facing roofs adding solar thermal to cut hot-water bills; self-builders specifying low-carbon from the outset; and landlords future-proofing rental yield against tightening MEES rules. When you need it At end of life of an existing system, during a major refurbishment, at new build first-fix, or whenever the next round of energy price changes makes the maths obvious. Why professional matters Renewables aren't a single product — they're a system. Specifying the wrong cylinder, undersizing emitters, missing grant deadlines or installing without MCS all kill performance and payback. Greencore's 30-year heating background makes the difference between a renewables system that works on paper and one that works in your home, in February, at 2 am. What it costs to delay ## The real consequences of putting it off Renewables done badly are worse than no renewables. Here's what we routinely come in and fix: ### Wrong-sized heat pump Oversized units short-cycle; undersized units never reach setpoint. Either way, the bill is 30–50% higher than the homeowner was promised. ### Missed grant windows The Boiler Upgrade Scheme has strict eligibility and submission rules. A missed step costs you £7,500. ### Solar thermal scaled wrong Panels too big, cylinder too small, no overheat protection — leads to stagnation, glycol degradation and panel failure. ### No fabric assessment Renewables on a draughty house are throwing money out of windows. We always assess fabric first and tell the truth. ### Lost warranty Non-MCS installs can't access most manufacturer warranty extensions and can't claim BUS funds. ### Common mistakes we fix #### Buying the panels first The system should be designed before the kit is bought. We see homeowners with garages full of orphaned panels they bought 'on offer'. #### Treating ASHP and solar as alternatives They're complementary. Solar thermal cuts the hot-water demand a heat pump has to satisfy — saving 30%+ in summer running costs. #### Skipping the cylinder A modern ASHP or solar thermal demands a properly specified unvented cylinder with a high-performance coil. Reusing the old one is the #1 cause of poor performance. Our Process ## A predictable, engineered process 1. STEP 01 ### Free renewables consultation We look at your home, your bills, your EPC and your goals. No commitment, no commission-driven sales — just a clear view of what's possible. 2. STEP 02 ### Fabric & heat-loss assessment Insulation, glazing, air-tightness, room-by-room heat loss. We won't install a system you don't have the fabric to support. 3. STEP 03 ### System design & grant submission Full MCS-compliant design pack: ASHP/solar/hybrid spec, emitter schedule, cylinder, controls, SCOP/SAP modelling, 4. STEP 04 ### Installation by our own team Greencore engineers do the install — outdoor unit, cylinder, pipework, emitter upgrades, controls — typically 3–7 days depending on scope. 5. STEP 05 ### Commission, monitor, support MCS commissioning certificate, smart-control handover, 12-month performance review and ongoing remote monitoring. Why it pays off ## Outcomes you can measure ### Honest renewables advice BUS grant scheme (£7,500 for heat pumps) is available — we'll point you to the application process, though we don't currently handle grants ourselves. ### Cut bills by 30–50% Well-designed heat pumps on off-peak tariffs typically halve oil-heating costs. Solar thermal can cover 60% of annual hot water demand. ### Lower carbon footprint Up to 75% lower CO₂ versus oil. As the grid greens further, the gap widens. ### MCS-grade (via partner) peace of mind Our certification protects your warranty, your grant, and your home's resale value. ### Quiet, automated, hands-off Modern systems run silently in the background with smart controls. You set it once, the system optimises. ### Future-proofed home Already aligned with future Boiler Upgrade Scheme rules and incoming low-carbon heating mandates. The Engineering Detail ## Under the bonnet Renewables is where heating engineering meets energy strategy. Here is the technical depth we bring: ### Air source heat pumps (ASHP) Monobloc R32 / R290 units, sized to MCS heat-loss surveys, with weather-compensated controls and matched indirect unvented cylinders. We install Mitsubishi Ecodan, Vaillant aroTHERM plus, Daikin Altherma and Samsung EHS. ### Ground source heat pumps (GSHP) For larger rural properties with land for slinkies or borehole capacity. SCOPs of 4.5+ when properly designed. Higher capital, lower running. We partner with accredited drilling contractors and handle the heating side end-to-end. ### Solar thermal (hot water) Flat plate or evacuated tube panels feeding a dual-coil cylinder. Best paired with families using a lot of hot water (4+ people, baths/showers daily). Sized to deliver 60% of annual hot water demand without overheating in summer. ### Hybrid systems ASHP for base load and the boiler for peak/defrost cycles. Ideal for older or harder-to-heat properties where a heat-pump-only design would require significant fabric upgrades. The hybrid runs on the cheaper of gas or electricity at any moment, automatically. ### Cylinders & buffer tanks Modern indirect unvented cylinders with 3.0–4.0 m² coils, expansion provision and Legionella cycle. Buffer tanks for very small homes or where multi-zone management requires hydraulic separation. ### Smart controls Weather compensation, load compensation, zone control, occupancy detection, tariff optimisation. Open APIs into Octopus Energy and Loop for tariff-aware operation. We build systems that get smarter, not dumber, over time. ### Grants & funding pathways BUS £7,500 for heat pumps (we handle); HUG2 means-tested funding for off-grid low-income homes (we'll advise); ECO4 referrals where appropriate; 0% VAT on most domestic renewables installs through 2027.
