Property Assessment & Heat Loss Survey

Every successful installation begins with understanding your property. Our assessment goes beyond a standard survey—we examine construction methods, insulation potential, existing heating infrastructure, and identify any conservation constraints.

You'll receive a detailed report covering heat loss calculations, recommended system specifications, expected running costs compared to your current system, and a breakdown of applicable grants.

For listed buildings, we include preliminary guidance on planning requirements and heritage considerations.

Air Source Heat Pump Installation

Air source systems extract heat from outside air, even in cold conditions down to -20°C. They're the most popular choice for retrofitting older properties because they require minimal ground works and can often be positioned discreetly.

Our installation package includes the heat pump unit, any necessary electrical upgrades, integration with your existing radiators or installation of new appropriately-sized emitters, hot water cylinder where required, and full system commissioning.

We work with leading manufacturers including Vaillant, Mitsubishi, Daikin, and Nibe to match the right system to your property's specific needs.

£8,450 starting from — typical range £8,450 to £14,500

Ground Source Heat Pump Installation

Ground source systems draw heat from the earth via buried pipes, offering higher efficiency than air source alternatives. They're particularly well-suited to properties with adequate outdoor space and where maximum efficiency is a priority.

We offer both horizontal loop installations (requiring significant garden area) and borehole systems (minimal surface disruption but deeper drilling). Our team handles all necessary groundwork, pipework installation, and system integration.

Ground source systems typically deliver a Coefficient of Performance (COP) of 4.0 or higher, meaning you get four units of heat for every unit of electricity consumed.

£14,950 starting from — varies based on loop type and property size

Hybrid Heating Systems

Some older properties—particularly those with solid walls and limited insulation potential—may benefit from a hybrid approach. We can design systems that combine a heat pump with a retained gas or oil boiler for peak demand periods.

This approach lets you benefit from renewable heating for the majority of the year while maintaining backup capacity for the coldest days. It's often a practical stepping stone for properties where a full heat pump installation isn't yet viable.

Hybrid systems also qualify for reduced grant support and can significantly cut carbon emissions while maintaining familiar heating patterns.

£6,750 starting from — depends on existing boiler compatibility

Listed Building Consultation

Installing renewable heating in a listed building requires careful navigation of planning requirements and heritage considerations. Our consultation service provides specialist guidance before you commit to a full installation.

We'll assess your property's listing status, review what similar properties have achieved, advise on positioning options that minimise visual impact, and prepare supporting documentation for planning applications.

Many listed building owners assume heat pumps are off-limits. In practice, with the right approach, approval rates are high—and we've achieved successful outcomes in properties dating back to the Tudor period.

Annual Maintenance Plans

Heat pumps require minimal maintenance compared to boilers, but annual servicing helps ensure optimal efficiency and catches minor issues before they become problems. Our maintenance plans provide peace of mind and protect your investment.

Each annual visit includes system health check, refrigerant pressure verification, filter cleaning or replacement, control system calibration, and performance efficiency reporting.

Maintenance plan customers also receive priority response times for any callouts and discounted rates on any repair work required outside standard servicing.

£185 per year — or £15.50 monthly direct debit

Government Grants Available

The Boiler Upgrade Scheme (BUS) offers significant financial support for heat pump installations.

Up to £7,500 Grant

Air source and ground source heat pump installations are eligible for grants of up to £7,500 through the BUS scheme.

Simple Eligibility

Most homeowners replacing a fossil fuel heating system qualify. The property must have an EPC and valid EPC recommendations.

We Handle Applications

Our team prepares and submits your BUS application as part of our service—no additional paperwork for you.

Instant Discount

The grant is applied directly to your invoice—you never have to pay the full amount upfront and claim back.
