How we chose
We started from every window cleaner Google Maps shows across Telford, from Wellington to Shifnal. Trade-body claims were sourced from the Federation of Window Cleaners, each firm's own site and the platforms checked, and anything found nowhere is shown as Can't be sourced [1]. Each business must first meet our basic checks: it is who it says it is, it is trading today and can be reached, and anything it must hold by law is in place. Eleven cleaners met all three and ten make the table. What customers say counts most toward the score, then qualifications, then whether the firm has traded two years or more and whether its cover is stated, then pricing clarity and website detail. All evidence is dated early September 2026.
How to hire
Match the cleaner to the job first. A regular round suits everyday glass, frames and sills every few weeks, and most Telford firms offer it by traditional squeegee or by water-fed pole using purified water that dries spot-free. Interiors are still done by hand, so say whether you want inside and out. When the brief runs wider, to mossy render, roofs, driveways, gutter clearing, fascias or solar panels, pick an exterior specialist instead, and for workplaces, schools or clinical sites pick a contract cleaner used to planned work.
Window cleaning needs no licence, so there is no mandatory register to check the way there is for gas or electrics. The voluntary body is the Federation of Window Cleaners, the trade association established in 1947, whose members carry liability insurance and work to a code of practice; ask for the membership and check it with the Federation directly before you book [1]. None of this round's ten claims membership, which is common for small rounds, and the table records that as Can't be sourced.
Ask how upper windows are reached. Ladders are not banned, but the safety executive says they should not be the automatic first choice, and much domestic work can be done from the ground with a pole [4]. For genuinely high work from platforms, the operator should hold a powered-access licence earned through training and a test at one of its training centres, so ask to see the card [8]. Whatever the method, ask to see the public-liability policy and check its dates cover your job, since most firms in this table state no insurance on their sites [5].
Get two or three written quotes on the same written brief, since a quote is a promise to do the work at an agreed price and having it in writing is what lets you prove it later [5]. Each quote should name every window, frame, sill and door, whether the clean is inside, outside or both, how often the round calls, what a first clean costs against the regular price, how access and parking are handled, whether VAT is added and how you pay. Treat an outlier far above or below the rest as a question rather than a bargain.
Make access easy on the day. Say where the outside tap is if poles need filling, where the van can park on your street, what moves out of the way in the garden and around the conservatory, and how pets and alarms are handled. Several firms in this table send a text the night before, so keep your phone on and reply if the date no longer suits. Agree how skipped or paused visits work before the round starts, so a holiday never becomes a missed-payment row.
Finish with paperwork, however small the job. Keep the invoice showing what was cleaned and when, the date of the next visit and any guarantee the firm offers on treatments such as soft-washed render. For a workplace or school, hold the contract, the named contacts, the insurance papers and any background checks the site needs on file. If the firm claims a scheme or association anywhere, check the membership on that body's own site rather than taking a logo at face value [6].
Pricing
As of autumn 2026, a regular exterior clean of a three-bed semi typically runs £15 to £40 a visit in modelled national guides, averaging around £25, with one-off cleans dearer than round prices [7]. Other 2026 guides put a three-bed regular round at £35 to £50 and starting prices for smaller homes from £30 [2] [3]. Telford usually sits below London and South East prices, which run well above the average [7].
Add-ons lift the bill but cost less booked together. Clearing the gutters of a standard house runs £40 to £120 depending on length and blockage, with downpipes sometimes extra [3] [7]. Fascias and soffits run £45 to £150, conservatory roofs anywhere from £30 for a wash-over to £250 for a deep algae clean, and solar panels £25 to £50 [3] [7]. A neglected first clean typically adds £10 to £30 on top of the round price [3].
Height and access move the price most: top-floor glass over a conservatory, limited rear access and town-centre parking all add time, as does heavy soiling and moss [2] [3]. Frequency pulls the other way, with regular customers often paying less than one-off prices [3]. Interiors add the inside half of the job, so an inside-and-out clean of the same house can run roughly double the exterior-only figure [7].
Published ranges exclude VAT unless stated, so ask whether it is added on top [2]. None of the ten firms in this table publishes example rates, offering free quotes or quote forms instead, so treat any single fixed figure for a large job with no breakdown as a question, not an answer. Get the scope, the first-clean price, the regular price and the VAT position in writing before work starts, and keep every quote and invoice together [5].
Red flags
Quotes a gutter, roof or render job without visiting or asking for photos of the work.
Cannot show a current public-liability policy when you ask, or its dates do not cover your job [5].
Reaches every awkward top window by ladder with no pole system and no discussion of safer access [4].
Gives one fixed figure for a large first clean with no breakdown of labour, materials and VAT.
Asks for full payment in cash before starting, with no written quote or terms [5].
Raises the agreed price on the day with no reason beyond its own costs going up [5].
Will not put the scope, the price and the next-visit date in writing before starting.
The bottom line
For most Telford homes, start with Taylors Window Cleaning Service: a plain regular round from one Dawley cleaner with the deepest review record in the table and a text before each visit. If you would rather price the job without a visit, Pure Clean Services takes photo quotes by form or message. Agree the scope and the regular price in writing before the first clean.
Match the firm to the job: Spitfire Softwash for render, roofs and driveways, Vortex Cleaning for high-level work and round-the-clock callout, and Cleanit Cleaning Services for contract cleaning across workplaces, schools and clinical sites. Then send the same written brief to two or three firms and compare itemised replies before you agree a round.
