Loft work is easy to sell badly. The loft is out of sight, most homeowners cannot judge what has been installed, and the results are difficult to check afterwards. That combination attracts a small number of operators who rely on pressure and vagueness rather than proper specification.
1. Pressure to decide today
Discounts that expire at the end of the visit, or a price that drops sharply after a phone call to a "manager", are sales techniques rather than pricing. A fair quote is still valid next week.
2. No written scope of work
A quote should state the material, the installed depth, the area covered, what is removed, and what is included. "Full loft insulation" on its own tells you nothing. Ask for depth in millimetres and area in m².
3. Confident claims about grants or savings
Nobody can promise a specific reduction in your energy bills, and grant eligibility depends on scheme criteria that change. Treat precise savings figures and guaranteed funding as sales copy.
4. Boarding fixed straight onto joists
If boards are laid directly onto the joists, the insulation beneath is compressed and loses much of its value. Raised boarding sits above the insulation layer. See raised loft boarding for how this should be done.
5. Ventilation never mentioned
Adding insulation changes how a loft behaves. If airflow at the eaves is not discussed at all, condensation risk has not been considered. Read do lap vents actually work?
6. Everything is an extra
Hatch draught-proofing, lap vents, tank and pipe insulation and waste removal are part of doing the job properly. When each one appears as a separate line item at the end, the headline price was not the real price.
7. No documentation afterwards
You should be left with a record of what was installed — materials, depths and the work carried out. That record matters later for surveys, sales and any future work.
Our rates are published on the pricing page, and the fixed price is confirmed before work is booked. If we do not think work is necessary, we will tell you.
