Mainteniq provides planned maintenance contracts, HIU servicing, heat pump servicing, 24/7 emergency air conditioning and heating repair and landlord compliance certificates across the Royal Borough of Greenwich for managing agents, RTM directors, Build-to-Rent operators and landlords, from Greenwich Peninsula and Woolwich to Kidbrooke and Eltham. Mainteniq is a London company with a Westminster office, and all gas work is done by Gas Safe registered engineers.

New-build blocks

Riverside and regeneration blocks of the last twenty years have communal heating, HIUs, fan coil air conditioning and MVHR. The work is mostly mechanical and the paperwork is the service record.

Older housing

Georgian and Victorian houses converted to flats in Blackheath, and estate housing such as the 1915 Progress Estate in Eltham. Boilers, electrics and landlord compliance dominate.

Licensing

Additional HMO licensing runs borough-wide from 1 January 2024 for three or more residents sharing facilities, alongside mandatory HMO licensing. Selective licensing covers lets to families, couples and single people in central Woolwich and Plumstead.

Heat networks in Greenwich: Peninsula and Royal Arsenal

On a heat network, responsibility for the HIU can sit with the network operator, the freeholder or the leaseholder, depending on the lease and the heat supply agreement.

01 · Greenwich Peninsula

Knight Dragon energy centre, set up 2016; network planned for 15,700 homes and 300,000 sq m of offices.

02 · Peninsula plant

Runs gas boilers and CHP now. Knight Dragon plans to add air source heat pumps.

03 · Royal Arsenal Riverside

SSE Energy Solutions appointed 2007 to design, build and operate; HIUs regulate heating in each home.

04 · SSE and HIUs

SSE's own case study says it maintains the HIUs under a 20-year contract.

If your block is on a network and the HIUs are your responsibility, or you want an independent service record, we can quote for the HIUs and the rest of the building's plant. We do not claim to operate or hold contracts on either network.

Greenwich Property Maintenance FAQ

Yes. Mainteniq services and repairs heat pumps across the Royal Borough of Greenwich, including Eltham. A visit covers filters and coils, refrigerant circuit leak checks, controls and flow temperature checks, and fault diagnosis, with refrigerant work carried out under our REFCOM F-Gas company certificate REF1024168. We do not sell or install heat pumps, so we can service equipment from any supplier.

It depends on the lease and the heat supply agreement. On some networks the operator maintains the HIUs, as SSE Energy Solutions states it does at Royal Arsenal Riverside in Woolwich under a 20-year contract, while in other blocks the freeholder or leaseholder is responsible. If the HIUs in your block are your responsibility, or you want an independent service record, we can quote for annual HIU servicing with a written, photographed report.

Mandatory HMO licensing applies across the borough. Royal Greenwich also runs an additional HMO licensing scheme borough-wide from 1 January 2024, covering smaller HMOs with three or more residents in separate households sharing a kitchen, bathroom or toilet, and a selective licensing scheme in central Woolwich and Plumstead. The council has consulted on a wider selective licensing scheme covering 18 wards, with no decision yet confirmed at the time of writing, so check the live position on the Royal Greenwich website before letting. We keep gas, electrical and PAT records current so licence applications are not delayed.

Landlords with gas appliances need an annual Gas Safety Certificate (CP12), carried out by a Gas Safe registered engineer. Private rented properties need an EICR at least every five years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. PAT testing is advisable where appliances are supplied, and communal air conditioning may need TM44 inspections and F-Gas leak checks. We co-ordinate these under one contract.

Yes. We run a 24/7 emergency line for air conditioning and heating faults with a same-day response target, and contract clients get priority. We cover the whole Royal Borough of Greenwich, including Greenwich Peninsula, Woolwich, Kidbrooke, Eltham, Blackheath, Charlton, Plumstead, Thamesmead and Abbey Wood.
