Heat pump radiators in Streatham: what to expect
In Streatham, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Radiator fitting in Streatham is scheduled with your heat pump installation so the system is drained only once. For period homes in Streatham and across Greater London, column radiators can keep the character of a room while giving enough heat at low temperatures.
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.
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Homeowners who want the lowest practical flow temperature for efficiency
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
Extensions and kitchen-diners around Streatham with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
Homes in Streatham can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Short winter days in Streatham and what they mean
Streatham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 37 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.

Heat pump radiator upgrades in Streatham: questions
How soon can you survey a home in Streatham?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Streatham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Streatham home states the expected time.
Do you cover Balham as well as Streatham?
Yes. We arrange surveys and installation in Balham, which is about a mile north-west of Streatham, and across Greater London.
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.
Do I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
