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.

We regularly work with homeowners who are still in the early stages of considering a heat pump. Before any quotes or designs are produced, we can review your property, insulation levels, and existing heating system to give you a clear idea of what’s actually suitable.

We’ll also help you understand what size system you’re likely to need and the key questions to ask when speaking to installers — so you go into the process informed, confident, and far less likely to end up with a poorly designed system.
If you're just thinking about a heat pump - f you’re still in the early stages and don’t yet have a design or quote, we can still carry out a full review based on your property.
We’ll assess your home, insulation levels, and current heating setup to determine whether a heat pump is suitable, what size system you’re likely to need, and what flow temperatures are realistically achievable. You’ll also get clear guidance on what to expect from installers, what should (and shouldn’t) be included in a proper design, and the key questions to ask when you start getting quotes. This means you go into the process informed, confident, and far less likely to end up with an undersized or poorly designed system.
Installing a heat pump is a significant investment — typically £8,000 to £15,000 or more. The Boiler Upgrade Scheme provides a £7,500 grant that makes the project financially viable for many homeowners. But the grant is tied to the installation, not to the quality of the design behind it.
The uncomfortable truth is that a large proportion of heat pump installations in the UK are underperforming — not because heat pumps don't work, but because the design behind them was wrong. The most common problems include:
Heat pump sized incorrectly for the actual heat loss of the home
Flow temperatures specified too high, reducing efficiency and increasing running costs
Radiators not checked for suitability at heat pump flow temperatures
Pipework design that creates flow rate problems
Cylinder sizing that doesn't match hot water demand
Designs produced quickly by salespeople rather than reviewed by engineers
None of these problems are visible on the day of installation. They become apparent over weeks and months — by which point the installer has been paid and the guarantee period is ticking.
This review is your opportunity to catch those issues before they become expensive.

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.
