Fixed-price M&E design packages

For homeowners, builders, installers and architects who need one piece of building-services design done properly, without a full consultancy appointment. Each package covers one house or flat. Prices are a starting point: send us the drawings and we'll confirm a fixed price before any work starts.

Heat pump design pack: from £495

Room-by-room heat loss calculation, heat pump sizing, and an emitter schedule (radiators or underfloor) designed for low flow temperatures. You get a design summary your installer can work from and that supports MCS and building control. Ideal for new builds under the Future Homes Standard, retrofits and extensions.

EV and maximum demand assessment: from £195

A maximum demand calculation for adding an EV charger, a heat pump or both, with advice on whether your supply needs upgrading and the information the network operator asks for. Useful before you order a charger or apply for a bigger supply.

Ventilation design: from £395

Ventilation rates to Part F, a mechanical extract or MVHR layout with duct routes, and commissioning flow rates for each room. Designed to work with an airtight house, so you avoid condensation and noisy, undersized systems.

What's included in every package

A fixed price agreed before we start. Design by a building-services engineer, not a sales team. Clear calculations and drawings in PDF, with Revit or CAD files on request. One round of revisions included.
