Heat pump radiators in Woolwich: what to expect
Homes around Woolwich range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Radiator fitting in Woolwich is scheduled with your heat pump installation so the system is drained only once. Many older houses in Woolwich still have their original single-panel radiators, so the survey checks each one against the room it heats.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Homeowners who want the lowest practical flow temperature for efficiency
- Extensions and loft conversions with large areas of glazing
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
In Woolwich, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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 Woolwich 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 Woolwich and what they mean
Woolwich sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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.
How installation works in Woolwich
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Woolwich; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Woolwich: questions
What size heat pump does a Woolwich home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Woolwich home.
Can you service a heat pump in Woolwich that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Woolwich, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Woolwich 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 Woolwich home.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
