Heat pumps run best in homes that hold heat and radiate it at low temperatures — which is why the honest first step in Wandsworth is a suitability assessment, not a sales visit. Some homes are ready today; some need insulation or radiator upgrades first; a few are better served by a modern boiler. We'll tell you which yours is.

Wandsworth heating notes: Wandsworth's hard water works steadily on cylinders and shower valves — in a borough full of loft-extended family terraces, scaled unvented systems are a recurring theme. Wandsworth is the natural home of the extended Victorian terrace — Balham, Earlsfield and 'between the commons' houses with loft bathrooms and unvented cylinders — plus the vast new riverside stock at Nine Elms and Battersea. Mains supply here is managed by Thames Water.

How a heat pump heats your home

The machine outside is half the story; the system design is the other half. Heat pumps deliver water at lower temperatures than gas boilers, which suits underfloor heating perfectly and requires radiators sized for the lower flow — sometimes existing ones suffice, often key rooms need upsizing. A hot water cylinder (heat-pump compatible) handles domestic hot water. Get the heat-loss survey, emitter sizing and cylinder right and a Wandsworth home runs beautifully on one; skip the design and no brand of hardware rescues it.

Costs, the grant, and honest arithmetic

Installed costs before support typically run £7,000–£14,000 depending on property size, emitter upgrades and cylinder work. The Boiler Upgrade Scheme grant — amount verified at quote time — comes off that for eligible homes in England and Wales, claimed by the MCS installer on your behalf with no paperwork burden on you. Running costs versus gas hinge on the system's efficiency and your electricity tariff; heat-pump-specific tariffs shift the comparison meaningfully, and our running-cost guide walks the real numbers.

Is your home suitable?

Three questions decide it. Can the fabric hold heat? — insulation standards matter more to a heat pump than to a boiler, and improving them first is sometimes the better first spend. Can the emitters run cool? — radiator sizing against a lower flow temperature is the crux of the design, checked room by room. Is there space? — an outdoor unit position and a cylinder location. Wandsworth homes pass or fail on specifics, not on age or style; plenty of period properties run happily on well-designed systems.

Installation, MCS and what you receive

What lands in your hands at the end: the MCS certificate, commissioning records showing design flow temperatures and settings, the grant handled and deducted, controls configured and explained (heat pumps reward set-and-leave running, not boiler-style on-off habits), and servicing guidance — an annual check keeps efficiency and warranty intact, and our network services what it installs. The handover conversation matters: homes new to heat pumps run them like boilers for the first month and wonder at the bills; run as designed, the economics arrive.

Coverage for air source heat pump installation runs right across Wandsworth — Battersea, Wandsworth Common and West Hill included — plus the surrounding Greater London area. Jobs route by proximity rather than by a call centre's guess at the map, which is why local engineers arrive with the right parts more often than not.

Frequently asked questions

How long does installation take?

Two to five days for most homes: outdoor unit, cylinder, any radiator upgrades, controls and commissioning. You'll have the honest schedule with your quote, including any day the heating or hot water is offline during changeover.

Do heat pumps work in cold UK winters?

Yes — modern units heat effectively well below freezing, and countries far colder than the UK run on them at scale. Efficiency dips on the coldest days, which the design accounts for; the system is sized to hold the house at temperature through a design-condition cold snap.

Do I need planning permission?

Usually not — most installations fall under permitted development, subject to rules about unit siting. Listed buildings and conservation areas have extra considerations. The survey flags anything relevant to your Wandsworth property before you commit.

How much does an air source heat pump cost in Wandsworth?

Typically £7,000–£14,000 installed before support, depending on property size, radiator upgrades and cylinder work. The Boiler Upgrade Scheme grant — amount confirmed at quote time — reduces that for eligible homes, claimed by the MCS installer on your behalf.
