Sudbury: your questions answered
Can I have air conditioning in a flat in Sudbury?
Often, yes, but the lease and the freeholder usually have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do I need planning permission for a heat pump in Sudbury?
It depends on the property. A conservation area takes in the middle of Sudbury. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Sudbury, normally Brent council).
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Do I need new radiators for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
About our air source heat pumps in Sudbury
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. The work covers homes heated by oil, LPG or gas, air-to-water heat pumps and radiator systems, and people most often call us about ageing boilers that will need replacing and questions about where the outdoor unit can go.
Terraced houses in a London area like Sudbury can suit a heat pump well, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Sudbury.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Make sure someone can let us in at the agreed time
- Tell us about any building rules, permits or sign-in
- Tell us about access, such as roof hatches, high walls or locked plant areas
Ask for a quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
Related advice
After we have gone
Simple habits make a real difference. We recommend:
- Read the manufacturer’s warranty terms for your brand
- Avoid switching the heat pump on and off often
- Find out the grant position at the survey
Should you have questions after the install, ring 07833 053749 and we will look into it. Annual servicing helps keep the system working well.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
How we price air source heat pumps
Every job gets its own quote. This is what makes a difference:
- The pipe route between the units
- The electrical supply and whether a new circuit is needed
- What state the existing equipment is in
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
Before you get in touch
Simple jobs can often be priced from pictures and some basics. Send what you can of the following:
- The fuse board and where it is in the property
- Any error code or flashing light on the display
- The outdoor side of the property, including any roof or flat area

Air source heat pumps around Sudbury
About 53% of homes in Sudbury and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Historic houses such as Northolt Manor, about 2.2 miles west, are a reminder that listed homes need consent before a heat pump goes in. If your home is near Sudbury & Harrow Road station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

Why act early in Sudbury
