Make Sure Your Heat Pump Design Is Right Before You Commit
Most heat pump problems don’t come from the unit — they come from the design. Whether you haven’t spoken to an installer yet or already have a heat loss and quotes in place, we give you a clear, independent view on what will actually work in your home. So you know you’re making the right decision before you commit.

If you're considering a heat pump, this review helps make sure the system is designed properly before you commit.
A heat pump installation is a significant investment, often costing £8,000–£15,000 or more. While the Boiler Upgrade Scheme can reduce the cost, it doesn't guarantee the design is right.
We independently review the proposed system to identify common issues before installation, including incorrect sizing, excessive flow temperatures, unsuitable radiators, poor pipework design, and hot water specification problems.
Whether you're comparing quotes, reviewing a completed design, or simply trying to understand what will work in your home, we'll help you make an informed decision before any work begins.
The goal is simple: avoid expensive mistakes and make sure the system is designed to perform properly from day one.

Heat loss calculation accuracy We review the heat loss calculation your installer has produced. We check the methodology, the inputs, and whether the result is plausible for a property of your size and construction. A heat loss that has been estimated rather than properly calculated is one of the most common causes of an oversized, inefficient system.

System sizing validation We check whether the heat pump model proposed is appropriately sized relative to the heat loss. Oversizing reduces efficiency and increases wear. Undersizing means the system can't meet demand in cold weather. Either is a problem.

Flow temperature specification The design flow temperature determines which radiators are adequate and sets the efficiency ceiling of the system. We check whether the proposed flow temperature is appropriate and whether the system has been designed to take advantage of weather compensation.

Radiator and emitter suitability We check whether your existing radiators or underfloor heating circuits are capable of delivering enough heat at the proposed flow temperature. Radiators designed for a boiler at 70°C often need upgrading to work at heat pump temperatures of 35–45°C — but many installers skip this check.

Cylinder sizing and hot water strategy Is the proposed cylinder size appropriate for your household's hot water demand? Is the immersion heater specification correct? Has the hot water strategy been properly considered alongside the space heating load?

Early-Stage Planning Advice If you’re just starting to consider a heat pump and don’t yet have a full design, we can guide you through the key decisions early on. This includes likely system sizing, flow temperature expectations, radiator suitability, and overall approach helping you avoid costly mistakes before speaking to installers.
Control strategy and zoning – We review how the system is intended to be controlled and whether multiple zones, buffers, low loss headers, or thermostats are likely to create performance issues.
