Size a home battery to your daily solar surplus, not your total consumption. This guide explains why, walks through a worked example, and covers when to size up for an EV, a heat pump, or time-of-use tariff arbitrage.

SCOP is the number that tells you how efficient a heat pump really is over a full heating season — not just on a perfect day. Here is how to read it, why flow temperature matters more than the headline figure, and how it connects to the £7,500 Boiler Upgrade Scheme grant.

Choosing the best air source heat pump for your UK home in 2026 means weighing SCOP efficiency ratings, noise levels, low-temperature performance, and total installed cost after the £7,500 Boiler Upgrade Scheme grant. This guide ranks the top models — Vaillant aroTHERM+, Daikin Altherma 3, Mitsubishi Ecodan, Samsung EHS, and Octopus Cosy — so you can make a confident, evidence-based choice.

Worried that your home isn't suitable for a full heat pump? A hybrid heat pump pairs a heat pump with your existing boiler to cut gas use gradually — without ripping out radiators, replacing pipes, or insulating first. Here's what's available in the UK in 2026, what it costs, and whether it makes sense for your home.

R290 (propane) is replacing R32 as the dominant heat pump refrigerant, driven by EU F-Gas regulations tightening from 2027. Samsung, Vaillant and Mitsubishi Heavy Industries have all launched R290 heat pumps in the UK or Europe — here is what that means for anyone buying a heat pump in 2026 and why future-proofing matters.

Air-to-air heat pumps became newly eligible for the Boiler Upgrade Scheme in 2025, receiving a £2,500 grant in England and Wales. This guide explains how the grant works, what air-to-air systems can and cannot do, who qualifies, and how an MCS-certified installer redeems the voucher on your behalf.

The rules around heat pump planning permission changed in May 2025: the one-metre boundary setback was scrapped, making it easier to install air source heat pumps under permitted development rights. This guide covers what changed, what still applies, and the edge cases — listed buildings, conservation areas, noise limits — where a planning application may still be needed.

Replacing a gas boiler with an air source heat pump is one of the biggest home decisions a UK homeowner faces in 2026. This guide compares installation costs, running bills at current tariff rates, maintenance, lifespan, carbon footprint, and the real policy position on the boiler ban — so you can make a confident, evidence-based choice.

How much does an air source heat pump actually cost to run in the UK? This guide walks through the maths — heat demand ÷ SCOP × electricity rate — with worked examples at April 2026 Ofgem price cap rates, a head-to-head against a gas boiler, the cases where heat pumps cost more or less, and practical tips on tariffs and insulation that can shift your bill by hundreds of pounds a year.

A heat pump does not burn fuel to create warmth — it moves heat from outside air or the ground into your home using a refrigerant cycle. This guide explains exactly how that works, what COP and SCOP mean, the difference between air source and ground source systems, and why a heat pump can deliver three units of heat for every unit of electricity it consumes.

Ground source heat pumps cost £15,000–£35,000 installed in the UK but qualify for a £7,500 BUS grant. SCOP 3.5–4.5 efficiency, 20-year lifespan, and stable winter performance — but you need a garden. This guide covers costs, horizontal loops vs boreholes, how GSHP compares to air source, and when a ground source system is the better long-term investment.

Heat pumps and underfloor heating are a natural pairing in UK homes. UFH operates at 35–45°C flow temperatures — exactly the range where heat pumps are most efficient. This guide explains the efficiency gains, wet vs electric UFH, retrofit options, and why new builds combining both will meet the 2025 Future Homes Standard.
