A job we did in HP1
Hemel Hempstead HP1
Samsung heat pump with Tesla Powerwall
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.
We install, service and repair air conditioning across Hemel Hempstead HP1. A single room is £2,400 to £3,200 fitted and a whole house is £8,400 to £11,300, with a free survey and a written price that does not change.
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.
What the housing in Hemel Hempstead means for the job
New town housing with consistent layouts, older cottages around the Old Town and Boxmoor, and enough space that almost anything is possible outside.
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.

NW7
Mill Hill
Vaillant aroTHERM plus air source heat pump
Gas boiler to heat pump in three days, with the grant approved within 48 hours. The unit stands on anti-vibration feet on a concrete pad close to the house, which keeps the pipe run short.

Barnet
Cascade pair of air source heat pumps
Two machines in cascade on a flat roof, flow and return in insulated copper with isolating valves on each leg, so one can be shut down and worked on while the other keeps the building warm.

Heat pump

Cockfosters
Vaillant aroTHERM plus 7 kW air source heat pump
Replaced an old gas boiler in three days. Raised on feet over a gravel bed at the side of the garden, so the defrost water drains away rather than pooling round the base.

Air conditioning pipework in a new nursery, first fix
A nursery still being built: the refrigerant pipework and control cables run through the ceiling void above the corridor and down a riser between floors, tied in and sealed, before the ceilings and walls are closed.

North Finchley
Samsung Gen 7 12kW high temperature heat pump
On wall brackets on the side of the house, clear of the ground, which keeps the side passage usable and the coil away from leaves and splashback.

Solar and battery

Cricklewood
Solar panels on ballasted frames, flat roof
Low-tilt frames standing on the pebble finish of a new-build flat roof and held down by weight, so nothing is fixed through the waterproofing, with a clear strip left along the parapet to walk and work from.

Cricklewood
Fox ESS hybrid inverter and CQ7 battery
The battery stands outside on the roof terrace on its own paving base, which these IP65 rated LFP modules are built for, with the inverter and the isolator on the wall above it and the cables dropped in one enclosed run.

See if it paysAir 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.
