Boilers, Heating& Air Conditioningin Welling

Most enquiries we get from Welling fall into a handful of categories: boiler replacements in 1930s semis; open-vented to combi conversions; smart thermostats such as hive; single-split ac for main bedrooms. Whichever applies to you, the starting point is the same. We look at the actual house, not a floor plan or a photo, and recommend what will work in those rooms.

Air conditioning in Welling

For Welling (DA16) homes we install three types of domestic system. A single-split pairs one indoor unit with one outdoor unit and suits a single bedroom, office or loft room. A multi-split runs several indoor units from one outdoor unit, so you get separate control in each room without a row of units on the outside wall. A ducted system hides the indoor unit in a loft or ceiling void and delivers air through discreet grilles, which suits renovations and homes where visible units aren't wanted.

We install Mitsubishi Heavy Industries, Mitsubishi Electric, Daikin, Fujitsu and Haier. GHS is F-Gas registered as a company and our engineers are personally F-Gas qualified, so refrigerant work is carried out and commissioned correctly. Installation starts from £1,500 with zero VAT until 31 March 2027, servicing from £150 + VAT, and AC repairs are £180 + VAT for the first hour, then £75 + VAT per additional half-hour.

Air-source heat pumps in Welling

A heat pump only performs well when it's designed around the house. That's why every heat pump enquiry from Welling starts with a survey for £250 + VAT, including heat-loss calculations and an assessment of radiators, hot water demand and where the outdoor unit and cylinder can go. We're approved installers for Baxi and Vaillant and hold heat pump installation and design certifications. Servicing starts from £220 + VAT and diagnostics are £180 + VAT for the first hour.

GHS is not directly MCS certified. We can arrange installations through an MCS umbrella scheme where applicable, so eligible customers can access the Boiler Upgrade Scheme grant.
