Hull's housing is unusually terrace-heavy, but the city is not one construction type. Victorian streets, inter-war suburbs, post-war estates and newer development around Kingswood can all fall within a short run of HU postcodes. The calculation has to follow the individual building, especially where rear additions have changed the original envelope.
Census 2021 recorded 84.5% of Hull households in a house or bungalow. Terraces alone represented 46.7%, compared with 29.4% in semi-detached homes and 8.4% in detached homes.
A party wall changes the exposed area, but it does not settle the rest of the fabric. Solid walls, altered rear returns and changes to windows, floors or roofs still need their own evidence.
Hull City Council's 2023-2027 stock strategy records 4,934 homes from before 1945, 7,455 from 1945-1964 and 8,504 from 1965-1980 within its own portfolio. It also notes both solid or narrow-cavity pre-war homes and a high proportion of non-traditional low-rise construction.
Those figures describe council-managed stock rather than every home in Hull, but they show why a postcode and age band are not enough to choose a wall assumption.
Ella Street retains long runs of two-storey Victorian terraces. Garden Village has an early twentieth-century estate layout surrounded by denser older streets, while Newington, St Andrew's, the Holderness Road corridor and Kingswood each have a different mix of regeneration, established housing and later development.

This HU11 house had seven surveyed rooms, eight windows, nine emitters and four floor-plan captures. The original property was recorded as solid brick, while the rear had three areas that could not be folded into a single construction assumption.
The kitchen occupied a two-storey 1967-1975 cavity-wall addition. A single-storey utility used solid brick beneath a sloping roof, and the bedroom above the jennel required its suspended floor to remain visible in the record. The accessible loft was recorded with 300 mm insulation.
The useful part of this record is the difference between the original solid-brick house and the three altered areas behind it. Each rear wall, roof or exposed floor condition remains attached to the room it affects.
The two-storey kitchen addition, single-storey utility and bedroom over the jennel each have a different wall, roof or floor condition. Keeping them separate prevents the original pre-1900 fabric from being applied across the whole rear of the house.
A city appointment and a wider HU-postcode visit can sit on very different routes. Hull's radial roads, dock traffic and the Humber crossings matter to the diary, so Cottingham, Hedon and a south-bank job are not treated as interchangeable slots.
Hull City Council identifies the A63 as the most congested part of the local network, with dock traffic from the east passing through the city centre. Journey time is checked before the appointment is confirmed rather than added as a generic allowance after booking.
Cottingham, Hessle, Anlaby and Willerby form a western cluster. Beverley sits north via the A1079 or A164, while Hedon, Preston, Bilton and the Holderness villages run east from the city. South-bank appointments use the A15 and Humber Bridge and are planned as their own route.
When checked on 16 July 2026, a directory using MCS data listed 30 certified air-source heat-pump installers within 30 miles of Hull, with 25 shown as Boiler Upgrade Scheme registered. These are radius figures, not 30 firms based inside the city boundary.

The report records each heated room, its dimensions, exposed elements, windows, doors, ventilation, construction assumptions and existing emitters. Rear additions and unusual exposed floors remain separate where they change the calculation inputs.
Yes, when the plans show the property as it stands today. Hull terraces and interwar semis often have rear extensions, converted roof rooms or altered openings, so a visit is usually better when those changes are missing from the drawings.
Coverage includes Hull, Cottingham, Hessle, Anlaby, Willerby, Beverley, Hedon, Preston, Bilton and surrounding HU postcodes. Vertex also supports installer projects throughout the UK.

The quote reflects the heated floor area, the records already available and whether measurements must be collected on site. Travel is confirmed from the full HU postcode before the appointment is accepted.
A standalone room-by-room report using a complete drawing and fabric pack, or a measured visit where those inputs are missing.
A single appointment for room data alongside proposed equipment positions, access, electrical details and installer evidence.
The booking reply states the agreed scope, travel position and expected report timing. For work beyond East Yorkshire, the UK heat loss service sets out the same measured and drawing-led options.
