Typical prices by premises type

We found six genuinely Hertfordshire-sourced prices, from two providers, running from £199 to £849 or more. Neither provider stated whether VAT is included. Everything else below is wider UK pricing shown for context, not Hertfordshire-specific, so don't mistake it for a local quote.

Source: published prices from 2 Hertfordshire-based providers, collected 2026-10-18 — £199 to £849 or more (6 published prices). Neither provider stated whether these prices include VAT, so treat every figure here as indicative, not like-for-like. "£849+" is that provider's own starting price for larger or higher-risk premises — the actual cost for a specific premises could be more. This is a small sample, not a market rate; always get a direct quote and ask what it includes.

Wider UK price context

These figures are not from Hertfordshire providers, and none of them should be read as a local quote. We show them only so you can see how the published Hertfordshire prices above compare with pricing pages from elsewhere in the UK.

Source: 11 UK fire risk assessment pricing pages, collected 2026-10-18, none Hertfordshire-specific. A further 5 pages that didn't state a premises type quoted figures from £169 to £1,300 (also a mix of VAT bases). Each range above blends sources on different VAT bases — the "price source" column states each one's basis, so compare like with like rather than reading the range as a single figure.

What affects the price

Floor area and number of storeys, the type of premises, whether people sleep there, and building complexity — a listed building, for example — all move the price. For blocks of flats, which of the four assessment types you need also matters.

Hertfordshire has a wide spread of listed buildings by district, from 93 in Watford to over 3,000 in East Hertfordshire, which can add time and cost to an assessment where a building's fabric needs closer inspection. For flats, a baseline Type 1 assessment of the common parts costs less than a Type 3 or Type 4 assessment that also samples inside individual flats, because that extra work usually needs access arranged with leaseholders. A new assessment, rather than a routine review, can also cost more if the assessor has no previous report to work from.

Cost for landlords and HMOs

Costs for landlords vary with the number of lettings, the number of shared areas, and whether the property is licensed as an HMO. See our full guide for landlords and HMOs for what the assessment needs to cover and how licensing fits in.

Cost for blocks of flats and communal areas

Blocks of flats cost more to assess as the building gets larger, taller or more complex, and as the assessment type moves from common-parts-only towards sampling inside individual flats. Our guide for flats and communal areas explains the four assessment types in full.

What you should get for the price

Whatever you pay, expect a written record of the assessment, its significant findings, and an action plan for anything that needs fixing. That written record is now a legal requirement for every assessment, not just larger premises, whoever carries it out.

When comparing quotes, ask each assessor what their price actually includes: a site visit, a written report, a prioritised action plan, and a named point of contact if you have questions afterwards. It's also reasonable to ask about their training and experience, since the law now requires anyone appointed to help with an assessment to be competent.

Frequently asked questions

What's the average cost of a fire risk assessment?

There isn't a single UK average we can stand behind with the data we have. The published Hertfordshire prices we found range from £199 to £849 or more across six price points from two providers, which is too small a sample to call a true average. Wider UK pricing pages, not specific to Hertfordshire, span roughly £150 to £900 for most commercial and residential premises.

What's the cheapest a fire risk assessment is likely to cost?

The lowest published Hertfordshire figure we found was £199, for a very small, single-person premises. Smaller and simpler premises generally cost less, but a genuinely low quote is worth checking against what it actually covers.

Does the price include VAT?

It varies by provider and often isn't stated clearly. Of the published UK prices we reviewed, about half don't say either way, the rest split between VAT-inclusive and plus-VAT. None of the Hertfordshire-specific prices we found states its VAT basis. Always ask a provider to confirm whether their quote includes VAT.

Why do quotes for the same premises type vary so much?

Floor area, number of storeys, whether anyone sleeps on the premises, and the complexity of the building (a listed building, for example) all affect how long an assessment takes, which drives the price. The type of assessment needed for a block of flats also varies, from a baseline check of common parts to one that samples inside flats as well.
