Heating, Heat Pumps & Air Conditioning in Marlow
Family-run, MCS certified heating and renewables engineers helping Marlow homeowners upgrade to heat pumps, high-efficiency boilers and air conditioning. From riverside period homes to large detached properties, we design systems that suit your house — not a one-size-fits-all package.
Premium upgrades for Marlow homes
Marlow's mix of riverside period property and large detached family homes makes it one of the best places in the county for thoughtful heating upgrades — and we know the SL7 housing stock well.
The streets around Higginson Park, Marlow Bridge and the riverfront are full of handsome older homes — Georgian and Victorian terraces, listed cottages and substantial detached houses set back from the Thames. These are beautiful properties to live in, but they were rarely built with modern heating in mind. We spend the time to understand each one: solid walls, generous room volumes and original features all change how a system should be sized. That groundwork is what lets us recommend the right boiler installation or a properly designed renewable system, rather than guessing.
A growing number of Marlow homeowners — particularly in Marlow Bottom and around Little Marlow, where many properties sit off the mains gas grid — are switching to air source heat pumps. For these homes a heat pump often makes far more sense than oil or LPG, and as MCS certified installers we can claim the £7,500 Boiler Upgrade Scheme grant on qualifying jobs. Where a gas boiler is still the right call, we frequently pair a Worcester Bosch system boiler with an unvented cylinder to give the strong, mains-pressure hot water that larger Marlow houses with multiple bathrooms need, alongside a full central heating upgrade.
Summers near the river can be warm and humid, which is why air conditioning has become a popular addition here. We fit discreet systems that cool in summer and provide efficient heating in the shoulder seasons, planning indoor and outdoor unit placement carefully so it sits sympathetically with period and riverside homes. Marlow is one of the towns we cover most often across Buckinghamshire, and being based just up the road in High Wycombe means short travel times and quick callouts.

Marlow heating FAQs
Do you install heat pumps in Marlow?
Yes. We are MCS certified for air source heat pumps and an accredited Vaillant aroTHERM installer, so we design and fit heat pumps for Marlow homes from start to finish. Because we are MCS certified, qualifying installations can claim the £7,500 Boiler Upgrade Scheme (BUS) grant, which we handle as part of the job.
Do you cover Marlow Bottom and Little Marlow?
Yes. We cover the whole of the SL7 postcode, including Marlow town centre, Marlow Bottom and Little Marlow, as well as the surrounding villages. We are based just up the road in High Wycombe, so travel times stay short.
Can you install air conditioning in a riverside property?
Yes. Air conditioning is a popular upgrade for Marlow homes near the Thames, where summers can feel warm and humid. We install discreet wall-mounted and multi-split systems that cool in summer and provide efficient heating in milder weather, and we will plan placement to suit period and listed properties sympathetically.
Will a heat pump work in an older Marlow home?
Yes, with the correct design. Older and period Marlow homes can run very happily on an air source heat pump once the system is properly sized and the emitters and pipework are matched to lower flow temperatures. We carry out a full heat-loss survey first so the system is designed around your home rather than fitted to a rule of thumb.
