A single or two-room system with the condenser at ground level against a flank wall. One to two days. The photograph above is a heat pump and a Tesla Powerwall on the same elevation, which is increasingly what people here ask for.

Heat pump and battery on the same elevation, so the pump can be run off stored generation through the evening peak instead of off the most expensive electricity of the day.
What the housing in Hemel Hempstead means for the job
HP1 is Hemel's Old Town, Boxmoor, Warners End and Gadebridge, and it is really two kinds of property. The post-war new town housing is remarkably consistent: similar layouts, similar plot widths, side access and gardens, which means a job here is predictable in a way a London terrace never is. The older stock around the Old Town and Boxmoor is Victorian and earlier, tighter, and occasionally listed or in a conservation area. Across both, outdoor space is generous by London standards and a condenser position is rarely the constraint.
Worth knowing before you book. Post-war housing frequently still has its original consumer unit with no spare way, so a dedicated fuse board at £350 is a common addition here. We check it at the survey rather than discovering it on the day.

Air conditioning in Hemel Hempstead: common questions
Do you come out to Hertfordshire?
Yes. The photograph on this page is an HP1 installation. Hertfordshire is normal work for us, particularly on the larger jobs.
No travel surcharge. Survey slots outside London are batched, so give us a little more notice on the date.
Can you do cooling, solar and a battery together?
Yes, and the job in the photograph is a heat pump alongside a Tesla Powerwall. Designing them together is cheaper than doing them separately because the electrical work and the certification are shared.
Price all four services in about a minute.
What does it cost out here?
£2,400 to £3,200 for a single room, and HP1 sits at the lower half because access and parking are not a problem.
Servicing is from £95 plus VAT, whoever fitted the system.
