Heat load surveys and system design in Hatfield
No two rooms in Hatfield gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
For self-builds and extensions in Hatfield, a standalone design pack can go straight to your builder. Hatfield sits around 11 miles from Watford, inside our Hertfordshire area. Postcode districts we cover here include AL10.
Prices in Hatfield
In the East of England, our guide range for heat load surveys and system design is £445–£1,395 for a standalone design pack, including VAT. That is above the UK middle, mainly because labour and access cost more in the East of England. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. As an example, the Design pack option (drawings and schedules for one home) would typically be £445–£895 here.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. On a survey in Hatfield the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
