Clear energy advice for UK homes and businesses
A heat pump, EV charger, solar array and battery can all be specified correctly and still be constrained by the incoming electrical supply. This guide explains how to assess a 100-amp single-phase service, when a DNO upgrade or three-phase conversion is justified, and how to sequence the work before renewables are installed.
An EPC can lag behind a well-executed retrofit because it is an asset assessment, not a live performance reading. This guide explains how assessors record heat pumps, solar PV and batteries, where evidence gaps appear, and how homeowners can check the lodged certificate against what was installed.
Export payments depend on a company that may not be there in three years' time. This guide explains how Supplier of Last Resort transfers affect SEG tariffs, meter data and credit balances, what records to keep, and how to restore payments quickly after a supplier failure.
Solar glare is often a seasonal, angle-specific effect rather than a permanent nuisance. This guide explains how UK homeowners and installers can design, document and discuss rooftop PV so that reflected light is less likely to become a dispute.
Most homeowners treat insurance as paperwork to tidy up after a renewable retrofit. That ordering is backwards. This guide explains what buildings and contents insurers actually need to know about roof-mounted PV, wall-mounted batteries and heat pumps — and why the commissioning file is also a claims file.
Solar diversion can turn a sunny afternoon into a warmer cylinder, but it can also repeat work a heat pump would have done more efficiently. This guide looks at cylinder losses, control settings and evening hot-water demand, and sets out how to audit the system before spending money in 2026.
A G100 export limitation scheme can be written into a home battery's connection agreement long before the homeowner sees a monitoring app. This guide explains the difference between the DNO's consented capacity and the inverter's configured ceiling, how to spot the limit in real data, and what commissioning evidence to insist on in 2026.
Solar panels are routinely sold on 25-year performance warranties, but the inverter sitting between them and your consumer unit is a power-electronics device with a far shorter working life. This guide sets out how UK homeowners can anticipate a replacement, interrogate the warranty small print, and avoid paying a winter emergency premium for a failure that was entirely foreseeable.
A rooftop solar system is bought for decades, but its components, roof and paperwork all have different expiry dates. This guide explains how UK homeowners and businesses can plan decommissioning at the outset, covering recycling routes, inverter disposal, roof reinstatement and the contract terms worth checking in 2026.
Two domestic solar quotations can specify the same panels, inverter and battery while differing by thousands of pounds because of how each installer has priced roof access. This guide explains the access items that belong in a 2026 quotation, the site conditions that drive cost, and how to compare offers without rewarding an optimistic omission.
Heat pump noise complaints are rarely about the decibel figure printed on a datasheet. They are about what arrives at a neighbour's window at eleven o'clock at night. This guide explains what the MCS 020 assessment actually establishes, why the predicted figure and the perceived disturbance can diverge, and which siting and retrofit measures genuinely reduce what is heard rather than simply relocating it.
Solar panels, batteries and heat pumps all pay back over decades, but in privately rented homes the person who funds the hardware is rarely the person who sees the savings. This guide examines the metering, consent and minimum-standard rules that shape rented-sector retrofits, and sets out four contractual structures that let landlord and tenant share the benefit rather than one side absorbing the cost.
Most renewable purchases begin with a quote rather than evidence. A month of half-hourly smart-meter data can reveal baseload, heating, hot-water and electric-vehicle patterns before a homeowner commits to solar, a battery or a heat pump.
Plug-in solar is marketed as a tenant-friendly route to lower bills, but UK flats present legal, electrical and physical constraints that deserve scrutiny. This guide sets out what a balcony array can realistically generate in 2026, how to approach landlords and freeholders, and which safety and metering questions to settle before purchase.
Quotes tell you what an installer would like to sell; the paper trail tells you whether they can stand behind it. This guide sets out how to verify MCS certification, insurance-backed guarantees, subcontracting arrangements and handover documents before releasing final payment.
Solar on a listed building is rarely a simple product choice; it is a heritage argument supported by drawings, product data and a credible alternatives appraisal. This guide explains how listed building consent differs from planning permission, what conservation officers typically expect in 2026, and how visible roof panels compare with hidden or ground-mounted arrays.
DNO approval is often the quiet constraint on a home renewables project. This guide explains when G98 and G99 notifications apply to solar, batteries and heat pumps, how export limitation fits in, and where domestic installations commonly stall.
The grant is not a discount sticker. In 2026, UK homeowners need to compare heat pump quotes as funding and engineering documents, with eligible costs, emitter sizing and commissioning shown separately.
Vehicle-to-home is no longer purely theoretical in the UK, but compatible cars, chargers and DNO approvals remain scarce. Here is how it compares with a dedicated home battery in 2026.
A green electricity tariff can be defensible, misleading or simply expensive, and the difference often sits in documents most buyers never request. This procurement guide explains what REGOs, fuel-mix labels and supplier claims actually demonstrate, and how an SME can write sustainability statements that survive scrutiny without paying for gloss.
