Trusted heating & boiler engineers in London

Installing a heat pump (air source or ground source) that is notifiable under Building Regulations must either be self-certified by an installer registered with an appropriate competent person scheme, or separately notified to and signed off by local authority building control — the same 'competent person scheme or building control' choice that applies to other notifiable building work.

The government's Boiler Upgrade Scheme, open in England and Wales and administered by Ofgem, gives upfront grants toward installing a heat pump or a biomass boiler. As Ofgem lists them, they are £7,500 off the cost and installation of an air-to-water, ground source or water source heat pump; £5,000 off a biomass boiler; £2,500 off an air-to-air heat pump, for residential properties only; and £9,000 off an air-to-water or ground source heat pump in an eligible off-gas-grid property, available until 31 March 2027.

To claim the Boiler Upgrade Scheme grant, Ofgem's guidance for installers says 'your business must be certified to install the relevant technology under the Microgeneration Certification Scheme (MCS)' — this is a funding-eligibility requirement, not a general legal requirement to install a heat pump, but it is a practical constraint on which installer a homeowner can use if they want the grant. The installer must pass the full value of the grant on to the property owner as an upfront discount, shown on the quote and on the invoice. The £9,000 value is only for an air-to-water or ground source heat pump in a property off the gas grid (not fuelled by mains gas, a capped or clamped supply still counting as mains gas; with no record of a gas meter point; not attached to a heat network; and not a new build) whose heating being replaced is fuelled by oil or liquefied petroleum gas (LPG). The new heating system must not be a hybrid that combines a heat pump with fossil fuel heating.

Where a rental property is heated by gas, the landlord's gas safety duties described in the gas trade record apply in full (annual Gas Safe check, Landlord Gas Safety Record, 28-day provision to tenants). For non-gas heating systems (e.g. oil boilers, electric storage heaters, heat pumps), no separate statutory safety-check or certificate regime for the heating system itself, distinct from the general gas safety and electrical safety regimes, was found for landlords in the sources checked — electric systems fall under the landlord's general electrical safety duties. Two duties do reach non-gas heating: keeping heating installations of any fuel in repair, and, on a tenancy the alarm regulations cover, a carbon monoxide alarm in any room used as living accommodation that contains a fixed combustion appliance other than a gas cooker, oil and solid fuel included (the next entries).

In England, section 11 of the Landlord and Tenant Act 1985 implies into a lease of a home granted for a term of less than seven years (section 13 of the same Act) a covenant by the landlord 'to keep in repair and proper working order the installations in the dwelling-house for space heating and heating water', whatever the fuel. In a flat, it can also reach an installation elsewhere in the building that serves the flat, such as a communal boiler (section 11(1A)). A term in the tenancy putting these repairs on the tenant has no effect, except for repairs the tenant is liable for under their duty to use the home in a tenant-like manner, and for anything the tenant is entitled to remove (section 11(2) and (4)).

In England, regulation 4 of the Smoke and Carbon Monoxide Alarm (England) Regulations 2015 requires the landlord of a tenancy the regulations cover to ensure that 'a carbon monoxide alarm is equipped in any room of the premises which is used wholly or partly as living accommodation and contains a fixed combustion appliance other than a gas cooker' (a bathroom or lavatory counts as such a room), that each alarm is 'in proper working order on the day the tenancy begins if it is a new tenancy', and that an alarm a tenant reports, and which is found not to be in proper working order, is 'repaired or replaced'. Regulation 2 and the Schedule leave some homes and tenancies out, including an HMO that needs a licence under Part 2 of the Housing Act 2004 and a house that needs one under Part 3.

The government's guidance on these regulations, which describes itself as a general guide rather than an authoritative interpretation of the law, explains that a fixed combustion appliance 'means a fixed apparatus where fuel of any type is burned to generate heat. Typically, these appliances are powered by gas, oil, coal, wood, etc., for example, gas or oil boilers, or log-burning stoves.' It also says the regulations 'apply to all social and private rented tenancies, other than those explicitly excluded in the Schedule to the Regulations'.
