A site visit and a written report telling you exactly where your premises stand against your workplace-temperature duty — and what it would take to fix. The lowest-cost way to turn a vague worry into a costed plan.
Regulation 7 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires that the temperature in all indoor workplaces be “reasonable”. The Approved Code of Practice sets a minimum of 16°C (13°C for strenuous work). It sets no maximum.
That absence is what people get wrong. There is no upper number to breach — but the duty to keep temperature reasonable still applies, and it sits alongside the general duty under the Health and Safety at Work etc. Act 1974 and the requirement to assess risk under the Management of Health and Safety at Work Regulations 1999. The TUC continues to press for a legal maximum of 30°C (27°C for strenuous work), with employer obligations from 24°C.
This page is general information, not legal advice. For a formal view on your obligations, take advice from your H&S adviser or a solicitor.
No obligation to buy anything. Plenty of surveys end with “shading and a ventilation change will do it” — and we will say so.
An engineer walks the site and records temperatures against occupancy, then identifies what is driving them: solar gain and glazing, orientation, insulation, equipment loads, occupancy density, ventilation and existing plant.
A short, plain-English document: measured conditions, the problem areas ranked, your position against the current duty, and costed options to fix each one.
Do it all now, phase it across budget years, or file the report as evidence that you assessed it. Either way you are acting on your timeline, not reacting to someone else’s.
Recorded temperatures by area and time, set against occupancy and use — so the picture is evidence rather than anecdote.
Which spaces are exposed, why, and how far outside a reasonable range they run in typical summer conditions.
A plain statement of where the premises sit against the current Regulation 7 duty and the thresholds under discussion.
Remedial options with indicative costs — from no-cost control changes and shading through to full mechanical cooling.
A sensible order of works so spend can be spread across budget years while risk comes down first where it is highest.
A dated document showing the duty-holder assessed the issue and acted — which is what matters if it is ever questioned.
If you already work with Renergy, the compliance survey is on us. For new commercial sites it is £200–£400 depending on size and location — credited against any remedial works you go on to place with us.
Not currently. Regulation 7 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires a “reasonable” temperature and sets a minimum, not a maximum. Campaigns — the TUC’s in particular — press for a legal maximum of 30°C, and 27°C for strenuous work, with employer obligations from 24°C. The duty to act reasonably already applies regardless.
£200–£400 per site for new commercial customers, depending on size and travel. It is free for Renergy’s existing customers, and credited against remedial works placed with us.
Most single sites take two to three hours on site. The written report follows within five working days.
No. The report is yours either way. Some sites need a full cooling system; plenty need shading, controls or a ventilation change, and we will tell you when that is the case.
Yes — estate-wide surveys are common. We report site by site and then give you a portfolio view so you can prioritise across the estate rather than site by site.
It is a competent contractor’s assessment of thermal conditions and options, dated and evidenced. It supports your risk assessment; it does not replace legal advice, and we will say so plainly in the document.
Tell us about the premises and we will arrange a visit, measure it properly, and put the position in writing.
