Questions from Thundridge
Is Thundridge within the area you cover?
Yes. Thundridge is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Is a heat pump in Thundridge permitted development?
The answer turns on the property and where the outdoor unit would sit. The Thundridge Wadesmill Conservation Area is close to the centre of Thundridge. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the planning department at East Hertfordshire council, normally the authority for Thundridge.
How much time does a heat pump install need?
The work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. The survey lets us set a firm programme, so call us on 07833 053749 or use the quote form to arrange one.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Thundridge and across Hertfordshire. Tell us who should receive the paperwork.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How we handle air source heat pumps in Thundridge
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers air-to-air heat pumps, radiator systems and underfloor heating, and common reasons people get in touch are checking eligibility for a heat pump grant and ageing boilers that will need replacing.
For a home around Thundridge that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Aftercare tips
Aftercare is straightforward, and it makes the next visit easier:
- Leave indoor units unobstructed
- Leave space around the outdoor unit
- Seal draughts where you can
We show you how to use the controls and explain how a heat pump works differently from a boiler. Steady running suits a heat pump better than switching on and off, and we’ll explain the settings for your home.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside so keep it unobstructed.
Homes in Thundridge and heat pumps
About 47% of homes in Thundridge and the neighbourhoods around it date from 1945 to 1972, according to VOA council tax data. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.
Live in one of the older houses around Parish Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status.

How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Pictures of the space and where the outdoor unit could go let us plan the work in Thundridge.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
How to prepare
- Keep pets and children away from the work area
- Make sure we can reach the consumer unit or fuse board
- Arrange for someone to be there to let us in
How to get a quote
Photos are the fastest route to a quote: 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. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
Pricing air source heat pumps in Thundridge
A fixed price needs a few facts first. We look at:
- One-off work versus a regular service cycle
- Whether it’s a simple split or a larger system
- How many units are involved
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before we start, with VAT shown clearly.
Before you get in touch
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- Your installation or service records
- The remote or wall controller showing any error
- Photos showing the indoor unit and the space around it
Quotes don’t take long. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
What we’re called out for in Thundridge
When a home is being extended or renovated, it’s a good moment to look at heat pumps. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Look out for these signs:
- Working out whether radiators need upsizing
- Working out where a cylinder could go
- Moving away from fossil-fuel heating
Historic houses such as Much Hadham Palace, about 4.8 miles east, are a reminder that listed homes need consent before a heat pump goes in.
Questions to ask before booking
- Which VAT rate the quote uses, and why
- Whether a new circuit is included and who certifies it
- Exactly what the price includes, from supply and fitting to commissioning
