Air source heat pump installation for Hornchurch homes
Every property in Hornchurch is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
In Hornchurch, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Installers working in Hornchurch plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
Terraced streets in Hornchurch often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Hornchurch quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Short winter days in Hornchurch and what they mean
Hornchurch sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Hornchurch: questions
How long does installation take in Hornchurch?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hornchurch home states the expected time.
Do I need new radiators for a heat pump in Hornchurch?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Hornchurch home gives a room-by-room list.
Where would the outdoor unit go on a Hornchurch house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Hornchurch home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
