Before you book: heat pump radiator upgrades in Catford
A heat pump suits most Catford homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
We plan radiator upgrades in Catford so floorboards are lifted only where pipework genuinely needs changing. Many older houses in Catford 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.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
Extensions and kitchen-diners around Catford with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
Homes in Catford 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 Catford and what they mean
On the shortest day Catford gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump radiator upgrades in Catford: questions
Where would the outdoor unit go on a Catford 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 Catford home.
Do I need new radiators for a heat pump in Catford?
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 Catford home gives a room-by-room list.
How long does installation take in Catford?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Catford home states the expected time.
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.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
